What is the Environmental Impact of Bitcoin Mining

Do you think most miners are still profitable after the recent price drops? Data from TokenInsight shows that some efficient miners incur an electricity cost of $1,400 per bitcoin mined.

Would a Bitcoin miner cost me more per month in electricity than a space heater?

Since they're calling for r/btc to be banned...

Maybe it's time to discuss bitcoin's history again. Credit to u/singularity87 for the original post over 3 years ago.

People should get the full story of bitcoin because it is probably one of the strangest of all reddit subs.
bitcoin, the main sub for the bitcoin community is held and run by a person who goes by the pseudonym u/theymos. Theymos not only controls bitcoin, but also bitcoin.org and bitcointalk.com. These are top three communication channels for the bitcoin community, all controlled by just one person.
For most of bitcoin's history this did not create a problem (at least not an obvious one anyway) until around mid 2015. This happened to be around the time a new player appeared on the scene, a for-profit company called Blockstream. Blockstream was made up of/hired many (but not all) of the main bitcoin developers. (To be clear, Blockstream was founded before mid 2015 but did not become publicly active until then). A lot of people, including myself, tried to point out there we're some very serious potential conflicts of interest that could arise when one single company controls most of the main developers for the biggest decentralised and distributed cryptocurrency. There were a lot of unknowns but people seemed to give them the benefit of the doubt because they were apparently about to release some new software called "sidechains" that could offer some benefits to the network.
Not long after Blockstream came on the scene the issue of bitcoin's scalability once again came to forefront of the community. This issue came within the community a number of times since bitcoins inception. Bitcoin, as dictated in the code, cannot handle any more than around 3 transactions per second at the moment. To put that in perspective Paypal handles around 15 transactions per second on average and VISA handles something like 2000 transactions per second. The discussion in the community has been around how best to allow bitcoin to scale to allow a higher number of transactions in a given amount of time. I suggest that if anyone is interested in learning more about this problem from a technical angle, they go to btc and do a search. It's a complex issue but for many who have followed bitcoin for many years, the possible solutions seem relatively obvious. Essentially, currently the limit is put in place in just a few lines of code. This was not originally present when bitcoin was first released. It was in fact put in place afterwards as a measure to stop a bloating attack on the network. Because all bitcoin transactions have to be stored forever on the bitcoin network, someone could theoretically simply transmit a large number of transactions which would have to be stored by the entire network forever. When bitcoin was released, transactions were actually for free as the only people running the network were enthusiasts. In fact a single bitcoin did not even have any specific value so it would be impossible set a fee value. This meant that a malicious person could make the size of the bitcoin ledger grow very rapidly without much/any cost which would stop people from wanting to join the network due to the resource requirements needed to store it, which at the time would have been for very little gain.
Towards the end of the summer last year, this bitcoin scaling debate surfaced again as it was becoming clear that the transaction limit for bitcoin was semi regularly being reached and that it would not be long until it would be regularly hit and the network would become congested. This was a very serious issue for a currency. Bitcoin had made progress over the years to the point of retailers starting to offer it as a payment option. Bitcoin companies like, Microsoft, Paypal, Steam and many more had began to adopt it. If the transaction limit would be constantly maxed out, the network would become unreliable and slow for users. Users and businesses would not be able to make a reliable estimate when their transaction would be confirmed by the network.
Users, developers and businesses (which at the time was pretty much the only real bitcoin subreddit) started to discuss how we should solve the problem bitcoin. There was significant support from the users and businesses behind a simple solution put forward by the developer Gavin Andreesen. Gavin was the lead developer after Satoshi Nakamoto left bitcoin and he left it in his hands. Gavin initially proposed a very simple solution of increasing the limit which was to change the few lines of code to increase the maximum number of transactions that are allowed. For most of bitcoin's history the transaction limit had been set far far higher than the number of transactions that could potentially happen on the network. The concept of increasing the limit one time was based on the fact that history had proven that no issue had been cause by this in the past.
A certain group of bitcoin developers decided that increasing the limit by this amount was too much and that it was dangerous. They said that the increased use of resources that the network would use would create centralisation pressures which could destroy the network. The theory was that a miner of the network with more resources could publish many more transactions than a competing small miner could handle and therefore the network would tend towards few large miners rather than many small miners. The group of developers who supported this theory were all developers who worked for the company Blockstream. The argument from people in support of increasing the transaction capacity by this amount was that there are always inherent centralisation pressure with bitcoin mining. For example miners who can access the cheapest electricity will tend to succeed and that bigger miners will be able to find this cheaper electricity easier. Miners who have access to the most efficient computer chips will tend to succeed and that larger miners are more likely to be able to afford the development of them. The argument from Gavin and other who supported increasing the transaction capacity by this method are essentially there are economies of scale in mining and that these economies have far bigger centralisation pressures than increased resource cost for a larger number of transactions (up to the new limit proposed). For example, at the time the total size of the blockchain was around 50GB. Even for the cost of a 500GB SSD is only $150 and would last a number of years. This is in-comparison to the $100,000's in revenue per day a miner would be making.
Various developers put forth various other proposals, including Gavin Andresen who put forth a more conservative increase that would then continue to increase over time inline with technological improvements. Some of the employees of blockstream also put forth some proposals, but all were so conservative, it would take bitcoin many decades before it could reach a scale of VISA. Even though there was significant support from the community behind Gavin's simple proposal of increasing the limit it was becoming clear certain members of the bitcoin community who were part of Blockstream were starting to become increasingly vitriolic and divisive. Gavin then teamed up with one of the other main bitcoin developers Mike Hearn and released a coded (i.e. working) version of the bitcoin software that would only activate if it was supported by a significant majority of the network. What happened next was where things really started to get weird.
After this free and open source software was released, Theymos, the person who controls all the main communication channels for the bitcoin community implemented a new moderation policy that disallowed any discussion of this new software. Specifically, if people were to discuss this software, their comments would be deleted and ultimately they would be banned temporarily or permanently. This caused chaos within the community as there was very clear support for this software at the time and it seemed our best hope for finally solving the problem and moving on. Instead a censorship campaign was started. At first it 'all' they were doing was banning and removing discussions but after a while it turned into actively manipulating the discussion. For example, if a thread was created where there was positive sentiment for increasing the transaction capacity or being negative about the moderation policies or negative about the actions of certain bitcoin developers, the mods of bitcoin would selectively change the sorting order of threads to 'controversial' so that the most support opinions would be sorted to the bottom of the thread and the most vitriolic would be sorted to the top of the thread. This was initially very transparent as it was possible to see that the most downvoted comments were at the top and some of the most upvoted were at the bottom. So they then implemented hiding the voting scores next to the users name. This made impossible to work out the sentiment of the community and when combined with selectively setting the sorting order to controversial it was possible control what information users were seeing. Also, due to the very very large number of removed comments and users it was becoming obvious the scale of censorship going on. To hide this they implemented code in their CSS for the sub that completely hid comments that they had removed so that the censorship itself was hidden. Anyone in support of scaling bitcoin were removed from the main communication channels. Theymos even proudly announced that he didn't care if he had to remove 90% of the users. He also later acknowledged that he knew he had the ability to block support of this software using the control he had over the communication channels.
While this was all going on, Blockstream and it's employees started lobbying the community by paying for conferences about scaling bitcoin, but with the very very strange rule that no decisions could be made and no complete solutions could be proposed. These conferences were likely strategically (and successfully) created to stunt support for the scaling software Gavin and Mike had released by forcing the community to take a "lets wait and see what comes from the conferences" kind of approach. Since no final solutions were allowed at these conferences, they only served to hinder and splinter the communities efforts to find a solution. As the software Gavin and Mike released called BitcoinXT gained support it started to be attacked. Users of the software were attack by DDOS. Employees of Blockstream were recommending attacks against the software, such as faking support for it, to only then drop support at the last moment to put the network in disarray. Blockstream employees were also publicly talking about suing Gavin and Mike from various different angles simply for releasing this open source software that no one was forced to run. In the end Mike Hearn decided to leave due to the way many members of the bitcoin community had treated him. This was due to the massive disinformation campaign against him on bitcoin. One of the many tactics that are used against anyone who does not support Blockstream and the bitcoin developers who work for them is that you will be targeted in a smear campaign. This has happened to a number of individuals and companies who showed support for scaling bitcoin. Theymos has threatened companies that he will ban any discussion of them on the communication channels he controls (i.e. all the main ones) for simply running software that he disagrees with (i.e. any software that scales bitcoin).
As time passed, more and more proposals were offered, all against the backdrop of ever increasing censorship in the main bitcoin communication channels. It finally come down the smallest and most conservative solution. This solution was much smaller than even the employees of Blockstream had proposed months earlier. As usual there was enormous attacks from all sides and the most vocal opponents were the employees of Blockstream. These attacks still are ongoing today. As this software started to gain support, Blockstream organised more meetings, especially with the biggest bitcoin miners and made a pact with them. They promised that they would release code that would offer an on-chain scaling solution hardfork within about 4 months, but if the miners wanted this they would have to commit to running their software and only their software. The miners agreed and the ended up not running the most conservative proposal possible. This was in February last year. There is no hardfork proposal in sight from the people who agreed to this pact and bitcoin is still stuck with the exact same transaction limit it has had since the limit was put in place about 6 years ago. Gavin has also been publicly smeared by the developers at Blockstream and a plot was made against him to have him removed from the development team. Gavin has now been, for all intents an purposes, expelled from bitcoin development. This has meant that all control of bitcoin development is in the hands of the developers working at Blockstream.
There is a new proposal that offers a market based approach to scaling bitcoin. This essentially lets the market decide. Of course, as usual there has been attacks against it, and verbal attacks from the employees of Blockstream. This has the biggest chance of gaining wide support and solving the problem for good.
To give you an idea of Blockstream; It has hired most of the main and active bitcoin developers and is now synonymous with the "Core" bitcoin development team. They AFAIK no products at all. They have received around $75m in funding. Every single thing they do is supported by theymos. They have started implementing an entirely new economic system for bitcoin against the will of it's users and have blocked any and all attempts to scaling the network in line with the original vision.
Although this comment is ridiculously long, it really only covers the tip of the iceberg. You could write a book on the last two years of bitcoin. The things that have been going on have been mind blowing. One last thing that I think is worth talking about is the u/bashco's claim of vote manipulation.
The users that the video talks about have very very large numbers of downvotes mostly due to them having a very very high chance of being astroturfers. Around about the same time last year when Blockstream came active on the scene every single bitcoin troll disappeared, and I mean literally every single one. In the years before that there were a large number of active anti-bitcoin trolls. They even have an active sub buttcoin. Up until last year you could go down to the bottom of pretty much any thread in bitcoin and see many of the usual trolls who were heavily downvoted for saying something along the lines of "bitcoin is shit", "You guys and your tulips" etc. But suddenly last year they all disappeared. Instead a new type of bitcoin user appeared. Someone who said they were fully in support of bitcoin but they just so happened to support every single thing Blockstream and its employees said and did. They had the exact same tone as the trolls who had disappeared. Their way to talking to people was aggressive, they'd call people names, they had a relatively poor understanding of how bitcoin fundamentally worked. They were extremely argumentative. These users are the majority of the list of that video. When the 10's of thousands of users were censored and expelled from bitcoin they ended up congregating in btc. The strange thing was that the users listed in that video also moved over to btc and spend all day everyday posting troll-like comments and misinformation. Naturally they get heavily downvoted by the real users in btc. They spend their time constantly causing as much drama as possible. At every opportunity they scream about "censorship" in btc while they are happy about the censorship in bitcoin. These people are astroturfers. What someone somewhere worked out, is that all you have to do to take down a community is say that you are on their side. It is an astoundingly effective form of psychological attack.

Multi apartment clustered cryptocurrency mining rig

So you’ve probably just heard all your classes are online. And now you’re trying to sublet your apartment but no one’s gonna take it. So now you’re gonna be paying at least $1000/month for an empty apartment. I have a proposal that can reduce that cost and possibly turn a profit.
Firstly, we have a very high risk credit market on our hands. The Federal Reserve has been pumping money into the economy and at some point the US dollar will have to inflate while growth stagnates (aka stagflation). During stagflationary periods in the past the price of non-fiat currencies like gold or silver has skyrocketed. Recently cryptocurrencies have emerged with the same general economic properties of such commodities. Therefore we may see an increase in their values as the Fed keeps pumping more money into the economy.
As of now in order to generate enough money per month to pay off rent in South Campus Commons, each apartment would need a Bitcoin rig capable of generating ~2200 TH/s (since you don’t pay for electricity). For the Varsity and View this might have to be higher considering the cost of electricity. This is definitely possible with new ASIC chips that are solely built for the purpose of running Bitcoin hashing algorithms. For other cryptocurrencies (Ethereum, Litecoin, Dogecoin), these rates may be different. But like any good portfolio manager, diversifying our investments will ensure we have a profitable outcome.
If enough students come together to construct a Bitcoin mining rig in their apartments we could essentially create a multi apartment clustered miner to be able to generate Bitcoin. On top of that, because campus server resources will be diminished due to online classes, we can in turn utilize that computing power to help mine such cryptocurrencies. As a result we won’t have to find people to sublet our apartments to and won’t have to worry about the financial undertakings associated with it.
TL;DR: Corona collectively fucked everyone in the ass and we should build a massive Bitcoin rig to pay off our rent.

How Bitcoin Halving Will Affect BTC Price

Bitcoin Halving 2020

In every 210K mined blocks a planned (programmed) event takes place. This event is called halving. It is a regular reduction of miners’ fee (reward) for a produced block. Bitcoin creator put these halvings in software to keep inflation in check. Most commonly one block is being mined in 9 minutes and 20 seconds. According to this, halving occurs every four years. The Bitcoin network had two halvings: first in 2012 and then in 2016. If we look back and remember how much coins miners could earn in the early history of Bitcoin, it was 50 BTC for one block. Later on, after the first halving, the fee was equal to 25 BTC and the same happened four years after, then the reward was cut down to 12.5 BTC. The next (third) halving may be expected in May 2020. The payoff then will be reduced to 6.25 BTC. This will actually continue till there’s no award left (this will approximately happen in 2140).
So why is there a need for halving? If coins are produced very fast or the amount of emitted BTC is not limited, there will be so many Bitcoins in circulation that they will have limited value. Vitalik Buterin once said in his interview with Bitcoin Magazine: «The main reason why this is done is to keep inflation under control.»

What will happen with BTC price after Bitcoin halving?

Like any other cryptocurrency price prediction, the Bitcoin price prediction is always hard to make, so we can just guess looking at a combination of factors. Opinions are divided as follows: some think that the BTC price will go up and others think nothing will generally change and the price will stay the same. There are also skeptics that see the halving as bad luck. They believe that if even 10 percent of miners quit, it might scare away the investors and make them move out their assets. As a result, the Bitcoin price will go down. After the first Bitcoin halving the BTC price grew almost two hundredfold, the second time it grew sevenfold. Both times BTC had increased volatility. But no one can guarantee the same events nowadays. As far as we can see from the previous halvings, they had the same dynamics: the Bitcoin price grew up. This gives some people hope that it will repeat after the next BTC halving in May 2020.
What are people’s opinions and predictions regarding the next Bitcoin halving? Let’s have a look.

The CEO of Pantera Capital Dan Morehead predicts the rise of BTC after the coming halving:
“It’s right on the trend line, and I think it’s a good shot that by the end of the year, we hit that, and then if you just extrapolate that line out for another year, it’s $122,000 per Bitcoin and in one more year $356,000.”

Tom Lee from Fundstrat Global Advisors posted a part of the report regarding crypto outlook 2020. Here what is said regarding the BTC price in that report:
“For 2020, we see several positive convergences that enhance the use case and also the economic model for crypto and Bitcoin – thus, we believe Bitcoin and crypto total return should exceed that of 2019. In other words, we see strong probability that Bitcoin gains >100% in 2020.”

Bobby Lee (co-founder and CEO of BTC China) also expressed his opinion via twit saying:
“After next #BlockRewardHalving in Spring of 2020, new #Bitcoin output will drop again, to just 900 BTC/day. I predict #HashPower will continue to grow, with ever higher amounts of investment in mining (electricity costs). If that amount reaches $54m/day, we‘ll have $BTC at $60k.”

Jason A. Williams had an “unpopular opinion”:
“Unpopular Opinion – Bitcoin halving in May 2020 won’t do anything to the price. It will be a non-event.”

John McAfee is insanely positive as usual when speaking about the Bitcoin price prediction:
“When I predicted Bitcoin at $500,000 by the end of 2020, it used a model that predicted $5,000 at the end of 2017. BTC has accelerated much faster than my model assumptions. I now predict Bitcoin at $1 million by the end of 2020. I will still eat my d\ck if wrong.”*

Paolo Ardoino (Bitfinex & Tether Chief Technology Officer) said the following in his interview to U.Today:
“The halving is expected to occur next year, and I think it’s reasonable to expect an increase in the price of Bitcoin. I won’t do any price predictions myself and this is not financial or other advice from me or from Bitfinex or Tether, but I don’t see any reason for Bitcoin not hitting $100,000 within the next few years. That would already be an amazing goal for such technology.”

Tone Vays (Financial analyst) is less ambitious. That’s what he thinks:
“Technically, everything is in play until end of 2020, after that sub $5,000 is not likely. Worst Case Scenario: prices drop to $5k into the halving, then after halving 70% of miners shut down due to negative revenue, #Bitcoin spirals down in price but then rises from the dead!”

Petros Anagnostou, the founder of Crypto Solutions declares:
“My prediction: Bitcoin will reach $12,000 before the end of this year. And will reach a price of $50,000 – $100,000 by the end of 2020.”

To summarize, the forthcoming BTC halving 2020 will be a kind of guarantee that there will be no inflation, and investments will be profitable. At the same time, it is being one of the key factors responsible for the growth of the Bitcoin price. When it comes to miners, they usually feel stressed about it as to keep their income at the same level they will need to invest in new technical equipment. As for those who don’t mine but just buy Bitcoin to keep BTC as a cryptocurrency investment, the BTC halving will barely have any effect on them.
No one can predict what exactly will happen after the upcoming BTC halving. It is always up to you either be on the optimistic side or be one of the doubters.

Epic Cash AMA Recap with CryptoDiffer Community

CryptoDiffer team Hello, everyone! We are glad to meet here: Max Freeman (@maxfreeman4), Project Lead at Epic Cash Yoga Dude (@Yogadude), PR&Marketing at Epic Cash Xenolink (@Xenolink), Advisor at Epic Cash
Max Freeman Project Lead at Epic Cash Thanks Max, we are excited to be here!
Yoga Dude PR&Marketing at Epic Cash Hello Everyone! Thank you for having us here!
Xenolink Advisor at Epic Cash Thank you to the CryptoDiffer team and CryptoDiffer community for hosting us!
CryptoDiffer team Let`s start from the first introduction question: Q1: Can you introduce yourself to the community? What is your background and how did you join Epic Cash?
Yoga Dude PR&Marketing at Epic Cash
Hello! My background is Marketing and Business Development, I’ve been in crypto since 2011 started with Bitcoin, then Monero in 2014, Ethereum in 2015 and at some point Doge for fun and profit. I joined Epic Cash team in September 2019 handling PR and Marketing.
I saw in Epic Cash what was missing in my previous cryptos — things that were missing in Bitcoin and Monero especially.
Xenolink Advisor at Epic Cash
Hello Cryptodiffer Community, I am not an original co-founder nor am I a developer for the Epic Cash project. I am however a community member that is involved in helping scale this project to higher levels. One of the many beauties of Epic Cash is that every single member in the community has the opportunity to be part of EPIC’s team, it can be from development all the way to content producing. Epic Cash is a community driven project. The true Core Team of Epic Cash is our community. I believe a community that is the Core Team is truly powerful. EPIC Cash has one of the freshest and strongest communities I have seen in quite a while. Which is one of the reasons why I became involved in this project. Epic displayed some of the most self community produced content I have seen in a project. I’m actually a doctor of medicine but in terms of my experience in crypto, I have been involved in the industry since 2012 beginning with mining Litecoin. Since then I have been doing deep dive analysis on different projects, investing, and building a network in crypto that I will utilize to help connect and scale Epic in every way I can. To give some credit to those people in my network that have been a part of helping give Epic exposure, I would like to give a special thanks to u/Tetsugan and u/Saurabhblr. Tetsugan has been doing a lot of work for the Japanese community to penetrate the Japanese market, and Japan has already developed a growing interest in Epic. Daku Sarabh the owner and creator of Crypto Daku Robinhooders, I would like to thank him and his community for giving us one of our first large AMA’s, which he has supported our project early and given us a free AMA. Many more to thank but can’t be disclosed. Also thank you to all the Epic Community leaders, developers, and Content producers!
Max Freeman Project Lead at Epic Cash
I’m Max Freeman, which stands for “Maximum Freedom for Mankind”. I started working on the ideas that would become Epic in 2018. I fell in love with Bitcoin in 2017 but realized that it needs privacy at the base layer, fungibility, better scalability in order to go to the next level.
CryptoDiffer team
Really interesting backgrounds I must admit, pleasure to see the team that clearly has one vision of the project by being completely decentralized:)
Q2: Can you briefly describe what is Epic Cash in 3–5 sentences? What technology stands behind Epic Cash and why it’s better than the existing one?
Max Freeman Project Lead at Epic Cash
I’d like to highlight the differences between Epic and the two highest-valued privacy coin projects, Monero and Zcash. XMR has always-on privacy like Epic does, but at a cost: Its blockchain is over 20x more data intensive than Epic, which limits its possibilities for scalability. Epic’s blockchain is small and light enough to run a full node on cell phones, something that is in our product road map. ZEC by comparison can’t run on low end devices because of its zero knowledge based approach, and only 1% of transactions are fully private. Epic is simply newer, more advanced technology than prior networks thanks to Mimblewimble
We will also add more algorithms to widen the range of hardware that can participate in mining. For example, cell phones and tablets based around ARM chips. Millions of people can mine Epic that can’t mine Bitcoin, and that will help grow the network rapidly.
There are some great short videos on our YouTube channel https://www.youtube.com/channel/UCQBFfksJlM97rgrplLRwNUg/videos
that explain why we believe we have created something truly special here.
Our core architecture derives from Grin, so we are fortunate to benefit on an ongoing basis from their considerable development efforts. We are focused on making our currency truly usable and widely available, beyond a store of value and becoming a true medium of exchange.
Yoga Dude PR&Marketing at Epic Cash
Well we all have our views, but in a nutshell, we offer things that were missing in the previous cryptos. We have sound fiscal emission schedule matching Bitcoin, but we are vastly more private and faster. Our blockchain is lighter than Bitcoin or Monero and our tech is more scalable. Also, we are unique in that we are mineable with CPUs and GPUs as well as ASICs, giving the broadest population the ability to mine Epic Cash. Plus, you can’t forget FUNGIBILITY 🙂 we are big on that — since you can’t have true privacy without fungibility.
Also, please understand, we have HUGE respect to all the cryptos that came before us, we learned a lot from them, and thanks to their mistakes we evolved.
Xenolink Advisor at Epic Cash
To add on, what also makes Epic Cash unique is the ability to decentralize the mining using a tri-algo model of Random X (CPU), Progpow (GPU), and Cuckoo (ASIC) for an ability to do hybrid mining. I believe this is an issue we can see today in Bitcoin having centralized mining and the average user has a costly barrier of entry.
To follow up on this one in my opinion one of the things we adopted that we have seen success for , in example Bitcoin and Monero, is a strong community driven coin. I believe having a community driven coin will provide a more organic atmosphere especially when starting with No ICO, or Premine with a fair distribution model for everyone.
CryptoDiffer team
Q3: What are the major milestones Epic Cash has achieved so far? Maybe you can share with us some exciting plans for future weeks/months?
Yoga Dude PR&Marketing at Epic Cash
Since we went live in September of 2019, we attracted a very large community of users, miners, investors and contributors from across the world. Epic Cash is a very international project with white papers translated into over 30 languages. We are very much a community driven project; this is very evident from our content and the amount of translations in our white papers and in our social media content.
We are constantly working on improving our usability, security and privacy, as well as getting our message and philosophy out into the world to achieve mass adoption. We have a lot of exciting plans for our project, the plan is to make Epic Cash into something that is More than Money.
You can tell I am the Marketing guy since my message is less about the actual tech and more about the usability and use cases for Epic Cash, I think our Team and Community have a great mix of technical, practical, social and fiscal experiences. Since we opened our YouTube channels content for community submissions, we have seen our content translated into Spanish, French, German, Polish, Chinese, Japanese, Arabic, Russian, and other languages
Max Freeman Project Lead at Epic Cash
Our future development roadmap will be published soon and includes 4 tracks:
Usability
Mining
Core Protocol
Ecosystem Development
Core Protocol
Epic Server 2.9.0 — this release improves the difficulty adjustment and is aimed at making block emission closer to the target 60 seconds, particularly reducing the incidence of extremely short and long blocks — Status: In Development (Testing) Anticipated Release: June 2020
Epic Server 3.0.0 — this completes the rebase to Grin 3.0.0 and serves as the prerequisite to some important functional building blocks for the future of the ecosystem. Specifically, sending via Tor (which eliminates the need to open ports), proof of payment (useful for certain dex applications e.g. Bisq), and our native mobile app. Status: In Development (Testing) Anticipated Release: Fall 2020
Non-Interactive Transactions — this will enhance usability by enabling “fire and forget” send-to-address functionality that users are accustomed to from most cryptocurrencies. Status: Drawing Board Anticipated Release: n/a
Scaling Options — when blocks start becoming full, how will we increase capacity? Two obvious options are increasing the block size, as well as a Lightning Network-style Layer 2 structure. Status: Drawing Board Anticipated Release: n/a
Confidential Assets — Similar to Raven, Tari, and Beam, the ability to create independently tradable assets that ride on the Epic Blockchain. Status: Drawing Board Anticipated Release: n/a
Usability
GUI Wallet 2.0 — Restore from seed words and various usability enhancements — Status: Needs Assessment Anticipated Release: Fall 2020
Mobile App — Native mobile experience for iOS and Android. Status: In Development (Testing) Anticipated Release: Winter 2020
Telegram Integration — Anonymous payments over the Telegram network, bot functionality for groups. Status: Drawing Board Anticipated Release: n/a
Mining
RandomX on ARM — Our 4th PoW algorithm, this will enable tablets, cell phones, and low power devices such as Raspberry Pi to participate in mining. Status: Needs Assessment Anticipated Release: n/a
The economics of mining Epic are extremely compelling for countries that have free or extremely cheap electricity, since anyone with an ordinary PC can mine. Individual people around the world can simply run the miner and earn meaningful money (imagine Venezuela for example), something that has not been possible since the very early days of Bitcoin.
Ecosystem Development
Atomic Swaps — Connecting Epic to other blockchains in a trustless way, starting with ETH so that Epic can trade on DeFi infrastructure such as Uniswap, Kyber, etc. Status: Drawing Board Anticipated Release: n/a

From the Community aspect, we have been further developing our community international reach. We have been seeing an increase in interest from South America, China, Russia, Japan, Italy, and the Philippines. We are working on targeting more countries. We truly aim to be a decentralized project that is open to everyone worldwide.

You have 3 mining algorithms, the question is: how do they not compete with each other? Is there any benefit of mining on the GPU and CPU if someone is mining on the ASIC?
Max Freeman Project Lead at Epic Cash
The block selection is deterministic, so that every 100 blocks, 60% are for RandomX (CPU), 38% for ProgPow (GPU), and 2% for Cuckoo (ASIC) — the policy is flexible so that we can have as many algorithms with any percentages we want. The goal is to make the most decentralized and resilient network possible, and with that in mind we are excited to work on enabling tablets and cell phones to mine, since that opens it up to millions of people that otherwise can’t take part.

To Run a project smoothly, Funding is very important, From where does the Funding/revenue come from?
Xenolink Advisor at Epic Cash
Yes, early on this was realized and in order to scale a project funds are indeed needed. Epic Cash did not start with any funding and no ICO and was organically genesis mined with no pre-mine. Epic cash is also a nonprofit community driven project similar to Monero. There is no profit-driven entity in the picture. To overcome the revenue issue Epic Cash setup a development fund tax that decreases 1% every year until 2028 when Epic Cash reaches singularity with Bitcoin emissions. Currently it is at 7.77%. This will help support the scaling of the project.

Hi! In your experience working also with MONERO can you please clarify which are those identified problems that EPIC CASH aims to develop and resolve? What’s the main advantage that EPIC CASH has over MONERO? Thank you!
Yoga Dude PR&Marketing at Epic Cash
First, I must admit that I am still a huge fan and HODLer of Monero. That said:
✅ our blockchain is MUCH lighter than Monero’s
✅ our transaction processing speed is much faster
✅ our address-less blockchain is more private
✅ Epic Cash can be mined with CPU (RandomX) GPU (ProgPow) and Cuckoo, whereas Monero migrated to RandomX and currently only mineable with CPU

  1. the feature ‘Cut Through’ deletes old data, how is it decided which data will be deletes, and what are the consequences of it for the platform and therefore the users?
  2. On your website I see links to download Epic wallet and mining software for Linux,Windows and MacOs, I am a user of android, is there a version for me, or does it have a release date?
Max Freeman Project Lead at Epic Cash
  1. This is one of the most exciting features of Mimblewimble, which is its extraordinary ability to compress blockchain data. In Bitcoin, the entire history of a coin must be replayed every time it is spent, and comprehensive details are permanently stored in the blockchain. Epic discards spent transaction inputs and consolidates outputs, storing neither addresses or amounts, only a tiny kernel to allow sender and receiver to prove their transaction.
  2. The Vitex mobile app is great for today, and we have a native mobile app for iOS and Android in the works as well.

$EPIC Have total Supply of 21,000,000 EPIC , is there any burning plan? Or Buyback program to maintain $EPIC price in the future?
Who is Epic Biggest competitors?
And what’s makes epic better than competitors?
Xenolink Advisor at Epic Cash
We respect the older generation coins like Bitcoin. But we have learned that the supply economics of Bitcoin is very sound. Until today we can witness how the Bitcoin is being adopted institutionally and by retail. We match the 21 million BTC supply economics because it is an inelastic fixed model which makes the long-term economics very sound. To have an elastic model of burning tokens or printing tokens will not have a solid economic future. Take for example the USD which is an inflating supply. In terms of competitors we look at everyone in crypto with respect and also learn from everyone. If we had to compare to other Mimblewimble tech coins, Grin is an inelastic forever inflating supply which in the long term is not sound economics. Beam however is an inelastic model but is formed as a corporation. The fair distribution is not there because of the permanent revenue model setup for them. Epic Cash a non-profit development tax fund model for scaling purposes that will disappear by 2028’s singularity.

What your plans in place for global expansion, are you focusing on only market at this time? Or focus on building and developing or getting customers and users, or partnerships?
Yoga Dude PR&Marketing at Epic Cash
Since we are a community project, we have many developers, in addition to the core team.
Our plans for Global expansion are simple — we have advocates in different regions addressing their audiences in their native languages. We are growing organically, by explaining our ideology and usability. The idea is to grow beyond needing a fiat bridge for crypto use, but to rather replace fiat with our borderless, private and fungible crypto so people can use it to get goods and services without using banks.
We are not limiting ourselves to one particular demographic — Epic Cash is a valid solution for the gamers, investors, techie and non techie people, and the unbanked.

EPIC confidential coin! Did you have any problems with the regulators? And there will be no problems with listing on centralized exchanges?
Xenolink Advisor at Epic Cash
In terms of structure, we are carefully set up to minimize these concerns. Without a company or investors in the picture, and having raised no funds, there is little scope to attack in terms of securities laws. Bitcoin and Ethereum are widely acknowledged as acceptable, and we follow in their well-established footprints in that respect. Centralized exchanges already trade other privacy coins, so we don’t see this as much of an issue either. In general, decentralized p2p exchange options are more interesting than today’s centralized platforms. They are more censorship resistant, secure, and privacy-protecting. As the technology gets better, they should continue to gain market share and that’s why we’re proud to be partnered with Vitex, whose exchange and mobile app work very well.

What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment?
Max Freeman Project Lead at Epic Cash
Because our blockchain is so light (only 1.16gb currently, and grows very slowly) it is naturally well suited to become a decentralized mobile money standard because people can run a full node on their phone, guaranteeing the security of their funds. Scalability in Bitcoin requires complicated and compromised workarounds such as Lightning Network and light clients, and these problems are solved in Epic.
With our forthcoming Mobile Mining app, hundreds of millions of cell phones and tablets will be able to easily join the network. People can quickly and cheaply send money to one another, fulfilling the long-envisioned promise of P2P electronic cash.
As an investor, it’s important to ask a few key questions. Bitcoin Standard tokenomics of disinflation and a fixed supply are well proven over a decade now. We follow this model exactly, with a permanently synchronized supply from 2028, and 4 emission halvings from now until then, with our first one in about two weeks. Beyond that, we can apply some simple logical tests. What is more valuable, money that can only be used in some cases (censorable Bitcoin based on a lack of fungibility) or money that can be used universally? (fungible Epic based on always-on privacy by default). Epic is also poised to be a more decentralized and therefore resilient network because of wider participation in mining. Epic is designed to be Bitcoin++ Privacy, Fungibility, Scalability

Q1. What are advantages for choosing three mining algorithms RandomX+, ProgPow and CuckAToo31+ ?
Q2. Beam and Grin use MimbleWimble protocol, so what are difference for Epic? All of you will be friends for partners or competitors?
Max Freeman Project Lead at Epic Cash
RandomX and ProgPow are designed to use the entirety of a CPU / GPU’s unique processing capabilities in a way that other types of hardware don’t work as well. You can run RandomX on a GPU but it doesn’t work nearly as well as a much cheaper CPU, for example. Cuckoo is a “memory hard” algorithm that widens the range of companies that can produce the hardware.
Grin and Beam are great projects and we’ve learned a lot from them. We inherited our first codebase from Grin’s excellent Rust design, which is a better language for community participation than C++ that Beam currently uses.
Functionally, Mimblewimble is similar across the 3 coins, with standard Confidential Transactions, CoinJoin, Dandelion++, Schnorr Signatures and other advanced features. Grin is primarily ASIC-targeted, Beam is GPU-targeted, and Epic is multi-hardware.
The biggest differences though are in tokenomics and project structure. Grin has permanent inflation of 60 coins per block with no halvings, which means steady erosion of value over time due to new supply pressure. It also lacks a steady funding model, making future development in jeopardy, particularly as the per coin price falls. Beam has a for-profit model with heavy early inflation and a high developer tax. Epic builds on the strengths of these earlier mimblewimble projects and addresses the parts that could be improved.
Cryptodiffer Community Some privacy coin has scalability issues! How Epic cash will solve scalability issues? Why you choose randomX consensus algorithem?
Xenolink Advisor at Epic Cash
Fungibility means that you can’t distinguish one unit of currency from another, in example Gold. Fungibility has recently become a hot issue as people have been noticing Bitcoins being locked up by exchanges which may of had a nefarious history which are called Tainted Coins. In example coins that have been involved in a hack, darknet market transactions, or even processing coin through a mixer. Today we can already see freshly mined Bitcoins being sold at a premium price to avoid the fungibility problem Bitcoin carries today. Bitcoin can be tracked by chainalysis and is not a fungible cryptocurrency. One of the features that Epic has is privacy with added fungibility, because of Mimblewimble technology, Epic has no addresses recorded and therefore nothing can be tracked by chainalysis. Below I provide a link of an example of what the lack of fungibility is resulting in today with Bitcoin. One of the reasons why we chose the Random X algo. is because of the easy barrier of entry and also to further decentralize the mining. Random X algo can be mined on old computers or laptops. We also have 2 other algos Progpow (GPU), and Cuckoo (ASIC) to create a wider decentralization of mining methods for Epic.

I’m a newbie in crypto and blockchain so how will Epic Cash team target and educate people who don’t know about blockchain and crypto?
What is the uniqueness of Epic Cash that cannot be found in other project that´s been released so far ?
Yoga Dude Pr&Marketing at Epic Cash
Actually, while we have our white paper translated into over 30 languages, we are more focused on explaining our uses and advantages rather than cold specs. Our tech is solid, but we not get hung up on pure tech talk which most casual users do not need to or care to understand. As long as our fundamentals and tech are secure and user friendly our primary goal is to educate about use cases and market potential.
The uniqueness of Epic Cash is its amalgamation of “whats good” in other cryptos. We use Mimblewimble for privacy and anonymity. Our blockchain is much lighter than our competitors. We are the only Mimblewimble crypto to use a unique cocktail of mining algorithms allowing to be mined by casual miners with gaming rigs and laptops, while remaining friendly to GPU and CPU farmers.
The “uniqueness” is learning from the mistakes of those who came before us, we evolved and learned, which is why our privacy is better, we are faster, we are fungible, we offer diverse mining and so on. We are the best blend — thats powerful and unique

Can you share EPIC’s vision for decentralized finance (DEFI)? What features do EPIC have to support DEFI?
Yoga Dude PR&Marketing at Epic Cash
We view Epic as ideally suited to be the decentralized digital reserve asset of the new Private Internet of Money that’s emerging. At a technology level, atomic swaps can be created to build liquidity bridges so that wrapped Epic tokens (like WBTC, WETH) can trade on other networks as ERC20, BEP2, NEP5, VIP180, Algorand and so on. There is more Bitcoin value locked on Ethereum than in Lightning Network, so we will similarly integrate Epic so that it can trade on networks such as Uniswap, Kyber, and so on.
Longer term, if there is market demand for it, thanks to Scriptless Script functionality our blockchain has, we can build “Confidential Assets” (which Raven, Tari, and Beam are all also working on) that enable people to create tokenized assets in a private way.

If you could choose one celebrity to promote Epic-cash, who that would be?
Max Freeman Project Lead at Epic Cash
I am a firm believer that the strength of the project lies in allowing community members to become their own celebrities, if their content is good enough the community will propel them to celebrity status. Organic celebrities with small but loyal following are vastly more beneficial than big name professional shills with inflated but non caring audiences.
I remember the early days of Apple when an enthusiastic dude named Guy Kawasaki became Apple Evangelist, he was literally going around stores that sold Apple and visited user groups and Evangelized his belief in Apple. This guy became a Legend and helped Apple become what it is today.

How does $EPIC solve scalability of transactions? Current blockchains face issues with scalability a lot, how does $EPIC creates a solution to it?
Xenolink Advisor at Epic Cash
Epic Cash is utilizing Mimblewimble technology. Besides the privacy & fungibility aspect of the tech. There is the scalability features of it. It is implemented into Epic by transaction cut-through. Which means it allows nodes to remove all intermediate transactions, thus significantly reducing the blockchain size without affecting its validation. Mimblewimble also does not use addresses like a BTC address, and amount of transactions are also not recorded. One problem Monero and Bitcoin are facing now is scalability. It is evident today that data is getting more expensive and that will be a problem in the long run for those coins. Epic is 90% lighter and more scalable compared to Monero and Bitcoin.

what are the ways that Epic Cash generates profits/revenue to maintain your project and what is its revenue model ? How can it make benefit win-win to both invester and your project ?
Max Freeman Project Lead at Epic Cash
There is a block subsidy of 7.77% that declines 1.11% per year until 0, where it stays after that. As a nonprofit community effort, this extremely modest amount goes much further than in other projects, which often take 20, 30, even 50+ % of the coin supply. We believe that this ongoing funding model best aligns the long term incentives for all participants and balances the compromises between the ends of the centralized/decentralized spectrum of choices that any project must make.

Max already talked about our technical plans and goals in his roadmap. Allow me to talk more about the non technical 😁
We are aiming for broader reach in the non technical more mainstream community — this is a big challenge but we believe it is doable. By offering simpler ways to mine Epic Cash (with smart phones for example), and by doing more education we will achieve the holy grail of crypto — moving past the fiat bridges and getting Epic Cash to be accepted as means of payment for goods and services. We will accomplish this by working with regional advocacy groups, community interaction, off-line promotional activities and diverse social media targeting.

It seems to me that EpicCash will have its first Halving, right? Why a halving so soon?
Is a mobile version feasible?
Max Freeman Project Lead at Epic Cash
Our supply emission catches up to that of Bitcoin’s first 19 years after 8 years in Epic, so that requires more frequent halvings. Today’s block emission is 16, next up are 8, 4, 2, and then finally 0.15625. After that, the supply of Epic and that of BTC stay synchronized until maxing out at 21m coins in 2140.
Today we have a mobile wallet through the Vitex app, a native mobile wallet coming, and are working on mobile mining.
Cryptodiffer Community
What markets will you add after that?
Yoga Dude PR&Marketing at Epic Cash
Well, we are aiming to have ALL markets
Epic Cash in its final iteration will be usable by everyone everywhere regardless of their technical expertise. We are not limiting ourselves to the technocrats, one of our main goals is to help the billions of unbanked. We want everyone to be able to mine, buy, and most of all USE Epic Cash — gamers, farmers, soccer moms, students, retirees, everyone really — even bankers (well once we defeat the banking industry)
We will continue building on the multilingual diversity of our global community adding support and advocacy groups in more countries in more languages.

Almost, all cryptocurrencies are decentralized & no-one knows who owns that cryptocurrencies ! then also, why Privacy is needed? hats the advantages of Private coins?
Max Freeman Project Lead at Epic Cash
With a public transparent blockchain such as Bitcoin, you are permanently posting a detailed history of your money movements open for anyone to see (not just legitimate authorities, either!) — It would be considered crazy to post your credit card or bank statements to Twitter, but that’s what is happening every time you send a transaction that is not private. This excellent video from community contributor Spencer Lambert https://www.youtube.com/watch?v=0blbfmvCq\_4 explains better than I can.
Privacy is not just for criminals, it’s for everyone. Do you want your landlord to increase the rent when he sees that you get a raise? Your insurance company to raise your healthcare costs because they see you buying too much ice cream? If you’re a business, do you want your employees to see how much money their coworkers make? Do you want your competitors to trace your supplier and customer relationships? Of course not. By privacy being default for everyone, cryptocurrency can be used in a much wider range of situations without unacceptable compromises.

What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment?
Xenolink Advisor at Epic Cash
Epic Cash can be used as a Private and Fungible store of value, medium of exchange, and unit of account. As Epic Cash grows and becomes adopted it can be compared to how Bitcoin and Monero is used and adopted as well. As Epic is adopted by the masses, it can be accepted as a medium of exchange for store owners and as fungible payments without the worry of having money that is tainted. Epic Cash as a store of value may be a good long term aspect of investment to consider. Epic Cash carries an inelastic fixed supply economic model of 21 million coins. There will be 5 halvings which this month of June will be our first halving of epic. From a block reward of 16 Epic reduced to 8. If we look at BTC’s price action and history of their halvings it has been proven and show that there has been an increase in value due to the scarcity and from halvings a reduction of # of BTC’s mined per block. An inelastic supply model like Bitcoin provides proof of the circulating supply compared to the total supply by the history of it’s Price action which is evident in long term charts since the birth of Bitcoin. EPIC Plans to have 5 halvings before the year 2028 to match the emissions of Bitcoin which we call the singularity event. Below is a chart displaying our halvings model approaching singularity. Once bitcoin and cryptocurrency becomes adopted mainstream, the fungibility problem will be more noticed by the general public. Privacy coins and the features of fungibility/scalability will most likely be sought over. Right now a majority of people believe that all cryptocurrency is fungible. However, that is not true. We can already see Chainalysis confirming that they can trace and track and even for other well-known privacy coins today such as Z-Cash.

Do EPICs in 2020 focus more on research and coding, or on sales and implementation?
Yoga Dude PR&Marketing at Epic Cash
We will definitely continue to work on research and coding, with emphasis on improved accessibility (especially via smartphones) usability, security and privacy.
In terms of financial infrastructure will continuing to add exchanges both KYC and non KYC.
Big part of our plans is in ongoing Marketing and PR outreach. The idea is to make Epic Cash a viral sensation of sorts. If we can get Epic Cash adopters to spread the word and tell their family, coworkers and friends about Epic Cash — there will be no stopping us and to help that happen we have a growing army of content creators, and supporters.

I was watching some videos explaining how to send and receive transactions in EpicCash, which consists of ports and sending links, my question is why this is so, which, for now, looks complex?
Let’s talk about the economic model, can EpicCash comply with the concept of value reserve?
Max Freeman Project Lead at Epic Cash
In V3, which is coming later this summer, Epic can be sent over Tor, which eliminates this issue of port opening, even though using tools like ngrok.io, it’s not necessarily as painful as directly configuring the router ports. Early Lightning Network had this issue as well and it’s something we have a plan to address via research into non-interactive transactions. “Fire and Forget” payments to an address, as people are used to in Bitcoin, is coming to Epic and we’re excited to develop functionality that other advanced mimblewimble coins don’t yet have. We are committed to constant improvement in usability and utility, to make our money system the ease of use leader.
We are involved in the project (anyone can join the Freeman Family) because we believe that simply by choosing to use a form of money that better aligns with our ideals, that we can make a positive change in the world. Some of my thoughts about how I got involved are here: https://medium.com/epic-cash/the-freeman-family-e3b9c3b3f166

Huge thanks to our friends Maks and Vladyslav, we welcome everyone to come say hi at one of our friendly communities. It is extremely early in this journey, our market cap is only 0.5m right now, whereas the 3 other mimblewimble coins are at $20m, $30m and $100m respectively.

AT2: Asynchronous Trustworthy Transfers

AT2, a fairly new unknown tech to create a decentralized asset transfer system without blockchain.
This week there was an article @ www.computing.co.uk. See below.
link: https://www.computing.co.uk/feature/4017118/at2-answer-cryptocurrency-energy-performance
AT2 paper: https://arxiv.org/pdf/1812.10844.pdf

Could AT2 be the answer to cryptocurrency's energy and performance problems?
Blockchains are slow, wasteful and ill-suited for digital currencies, say researchers who believe they've found a better way
Blockchains solve a hard problem: how to ensure consensus across a distributed, decentralised network, where messages arrive out of order if at all, where individual nodes may fail, and where a certain proportion may be actively malicious.
The original blockchain, bitcoin, was designed to support a novel digital currency, and the issue its consensus algorithm solved was preventing double-spend. It also successfully introduced game theory for security: adversaries would have to spend more money on an attack than they could expect to gain financially. All this and the original protocol was just a few hundred lines of code.
But this achievement came at a high cost in terms of energy use and performance.
With bitcoin, a new leader is required to verify each block of transactions, that leader being the first device to complete a computationally heavy challenge (Proof of Work, PoW). As a result, the blockchain's throughput is painfully slow at around seven transactions per second (Visa claims it can do 56,000) and the whole process is massively wasteful of energy. These drawbacks have been surmounted, to some degree, in newer blockchain designs using overlay networks, sharding and different types of "proofs of" and by non-blockchain directed acyclic graphs (DAGs), but each requires tradeoffs in terms of centralisation, complexity or security.
A group of researchers led by computer scientist Professor Rachid Guerraoui of Swiss University Ecole Polytechnique Fédérale de Lausanne (EPFL) decided to look afresh at the problem. Is this gargantuan security apparatus, in which every node in a network of thousands or millions must come to a consensus about the ordering of events, really necessary everytime someone makes a purchase? Could a leaderless mechanism be applied to the problem instead? If so, could it be guaranteed to be reliably consistent, even when a certain number of nodes are malicious or faulty (Byzantine)?
The headline answer, published in an initial paper last year, is that network-wide consensus is overkill for simple asset transfers. If cryptocurrencies could be rebooted, all the fossil fuels burned by miners of bitcoin and its clones could be left in the ground and Visa-level transaction speeds could be achieved without any loss of security or reliance on centralised control. As compact as Satoshi's original bitcoin protocol itself, the few hundred lines of code that make up their Asynchronous Trusted Transfers (AT2) algorithm could solve some of the tricky problems that have plagued decentralised token-based networks from the off.
AT2 can be used to validate transactions within two different decentralised networking scenarios: (1) permissioned or small unpermissioned networks, and (2) global scale unpermissioned networks. In the first case, the algorithm uses quorum for validating actions, whereby a certain proportion of the network's nodes must agree an action is correct before it can take place. The second scenario, networks made up of very large number of machines (nodes), uses probabilistic sampling. Instead of asking all nodes it checks a number of randomly selected nodes for their viewpoint. This is much more efficient and scalable than the deterministic quorum but carries a tiny (ca. 10-15) possibility of failure.
Doing away with network-wide consensus means AT2 sidesteps the bane of decentralised networks, the FLP Impossibility - the theory that in a fully asynchronous system, a deterministic consensus algorithm cannot be safe, live and fault-tolerant.
Computing caught up with Matteo Monti, who worked on the statistical aspects of AT2, and by email with Guerraoui to find out more. We also spoke to David Irvine of networking firm MaidSafe, which has adopted AT2 to simplify its consensus process.

Incentivising improvements
We asked Monti (pictured) to summarise the innovation that AT2 brings to the table.
"What we noticed is that there's a specific subclass of problems that can be solved on a decentralised, distributed network without requiring consensus," he said. "The main use for consensus at the moment, cryptocurrency transactions, is part of that class. We can solve this using a weaker abstraction and in doing so you gain the ability to work in a completely asynchronous environment."
Bitcoin doesn't even solve consensus well. It solves eventual consensus which an even weaker abstraction, he added, whereas AT2 can guarantee strong eventual consistency. Another issue it tackles is PoW's incentivization model which means that improvements in technology do not translate into a better performing network.
"With bitcoin, the bottleneck is always electricity. If everyone doubles their computational speed it's not going to change the efficiency of the network. Everyone's competing not to compute but to waste energy."
In place of PoW, AT2 uses ‘Proof of Bandwidth', i.e. evidence of recent interaction, to verify that a node is real. Since it doesn't rely on consensus, the performance of AT2 should allow messaging speeds across the network that approach the theoretical maximum, and improvements in hardware will translate into better overall performance.

Security measures
Blockchains like bitcoin are extremely resilient against Sybil attacks; bitcoin is still running after all, in the face of unwavering opposition from powerful nation states and bankers. Sybil attacks are a major vulnerability in permissionless decentralised networks where anyone can join anonymously, but there are others too.
Monti said the most challenging aspect of designing the AT2 algorithm was distilling all the potential types of dangerous Byzantine behaviour into a manageable set so they could be treated using probability theory. As a result of studying many possible failure scenarios, including Sybil, the algorithm is able to quickly react to deviations from the norm.
Other security features flow from the fact that each network node needs to know only a limited amount about its counterparts for the system to function. For example, the randomness used in sampling operations is generated locally on the calling device rather than on the network, making this vector hard to utilise by an attacker looking to influence events.
Signals are passed across the network via a messaging system called Byzantine Reliable Broadcasting (BRB) a gossip-based method by which nodes can quickly and reliably come to an agreement about a message even if some are Byzantine.
As a result of these features, AT2 does not rely on economic game theory for security, said Monti.
"I'd go as far as saying that the moment you need to implement an economic disadvantage to attacking the system, it means that you failed to make it impossible to attack the system. We don't care about your interests in attacking the system. What we want to achieve is a proof that no matter what you do, the system will not be compromised."

‘Crypto-Twitter'
AT2 starts with the simple idea that rather than requiring the whole network to maintain a time-ordered record of my transactions (as with a blockchain or DAG), the only person who needs to keep that tally is me.
If I decide to spend some money, I merely announce that fact to the network over BRB and this request will be held in a memory snapshot escrow. Depending on the network type, a representative sample or a quorum of other nodes then check my balance and inspect my ordered transaction history to ensure that the funds haven't already been spent (each transaction has a unique sequential ID) and provided all is correct the transaction is guaranteed to go through, even if up to a third of those validators are malicious. If I try to cheat, the transaction will be blocked.
Monti likens a wallet on an AT2 network to a social media timeline.
"What we've proved, essentially, is that you can have a cryptocurrency on Twitter," he explained.
"A payment works in two steps. First, there's a withdrawal from my account via a tweet, then the second step is a deposit, or a retweet. I tweet a message saying I want to pay Bob. Bob then retweets this message on his own timeline, and in the act of retweeting he's depositing money in his account.
"So everyone has their own independent timeline and while the messages - my tweets - are strictly ordered, that's only in my own timeline; I don't care about ordering relative to other timelines. If I try to pay someone else, it will be obvious by the sequence of tweets in my account, and my account only, whether I can perform that payment.
"In contrast, consensus effectively squeezes all of the messages into a unique timeline on which everybody agrees. But this is overkill, you don't need it. We can prove that it still works even if the ordering is partial and not total, and this enables us to switch from consensus to reliable broadcast."
But of course, nothing comes for free. AT2 can verify exchanges of tokenised assets, but aside from arrangements between a small number of opted-in parties, it does not have the ability to support smart contracts of the type that are viable on ethereum and other blockchains, because this does require network-wide consensus. Guerraoui said his team is working on "refinements and extensions" to support such functionality in the future.

Early adopters
AT2 is still pretty ‘cutting edge'. Three papers have been accepted for peer review the latest published in February, but it provides the sort of efficiencies and simplifications that could bring real progress. Guerraoui said AT2 has "received interest from many groups including companies ‘selling' blockchain approaches, as well as companies and organisations using such approaches".
One organisation that has already picked up on the potential of AT2 is Scotland's MaidSafe, creator of the SAFE Network. MaidSafe is already using AT2 to replace its Parsec consensus algorithm, which testing showed was indeed overkill for many network operations. CEO David Irvine said he and his colleagues came across AT2 while working on another way of propagating changes to data without consensus, conflict-free data replicated types (CRDTs), promptly forked the code and started to apply it.
SAFE, currently in Alpha, is a sharded network, meaning it's subdivided into small semi-autonomous sections. On a network level, the way it works is that trusted 'elder' nodes vote on a requested action then pass instructions to other sections to carry it out.
AT2 allows the initial task of accumulating the votes for an action, which had been done by the elders using a consensus algorithm, to be moved off the network and onto the requesting client which is much more lightweight and efficient. Once a quorum of votes has been gathered, the client simply resubmits the request and the elders will ensure it's carried out. The system is much simpler and should be more secure too. "It's 200 lines of logic compared to 15,000 for a start," Irvine said.
AT2 is not just used to validate token transfers. By the same mechanism, it can also be used to authorise requests to store or change data. Together with CRDTs, which guarantee that such changes cannot fail, this makes for a very tight and efficient ship, said Irvine.
"AT2 is for us a missing link. The difficulty of several nodes agreeing is simplified by the initiator taking on the effort of accumulating quorum votes. It seems so simple but in fact, it's an amazing innovation. It certainly falls into the category of 'why didn't I think of that?'."

Ethereum 2.0: Why, How And Then?

Ethereum 2.0: Why, How And Then?
Why update Ethereum? One problem of the Ethereum network that the update should solve is scalability. At the moment, its blockchain can perform to 15 transactions per second, which is over two times more than that of bitcoin. However, this speed is still not enough for a large number of users. For example, the Visa payment system can perform up to 24 thousand transactions per second.
Adding an Optimistic Rollup technology will help to solve the scalability problem. According to Vitalik Buterin, the creator of Ethereum, its implementation will occur after the network’s update and will increase its throughput to 1000 transactions per second.
by StealthEX
Another solution to this problem is a change in the algorithm. Currently, Ethereum runs on the same protocol as Bitcoin, Proof-of-Work, confirmation of transactions in the cryptocurrency network occurs using the computing power of processors.
Using the Proof-of-Work algorithm limits the growth of the Ethereum network bandwidth. To withstand a large load, more miners are needed, but the growth of their number slows down since it becomes more difficult to mine cryptocurrency and, consequently, less profitable.
This is the reason the Ethereum development team is planning to switch to the Proof-of-Stake algorithm. Unlike the PoW, it does not require the use of computing power to confirm blocks. Instead of miners, transactions will be confirmed by validators. To become a validator, the user should have 32 ETH and install a special client. From a technical point of view, this is easier than buying mining devices and maintaining their functionality, as well as looking for access to cheap electricity. Thus, the system will no longer need expensive hardware.
The main solution to the scalability problem will be to implement sharding. Current Ethereum network is a unified database. After the update, the blockchain will be divided into autonomous, interacting blocks — shards, each of which will process particular transactions and smart contracts, which, however, will be recognized by the entire Ethereum blockchain. Nodes that form the shard process information separately, this allows maintaining the principle of decentralization. This is important since the risk of centralization is another big problem of the old algorithm.
Since the complexity of mining has increased over time, and now this process requires having expensive equipment and access to cheap electricity, small participants can not afford to stay in the game. In such conditions, big pools of miners that can provide higher productivity have a decisive advantage. For example, in April, more than 50% of the computing power of the Ethereum network was provided by only two mining pools. This creates a significant risk of centralization and “51% attacks”.
Validators will confirm transactions and get rewards in the form of passive income. According to the project’s roadmap, this amount will vary from 1.81% to 18.1%. The profitability of the stacking will depend on the number of validators. The more of them, the smaller the amount they get. However, there will be some costs. In the same Ethereum 2.0 roadmap, developers mentioned that the cost of validating transactions, based on rough calculations, will be about $180 per year. One of the developers of the project, Justin Drake, predicts that on average the validator will receive an income of 5% per year.

What is the estimated Ethereum 2.0 release date?

The launch of Ethereum 2.0 will take place gradually, in six stages, the “zero” of which is expected this summer. However, it is worth noting that due to finding vulnerabilities, the dates have already been shifted several times–initially, the transition to the new version was planned in 2019.
One of the developers of the project, Afri Schoedon, said that the launch could be postponed to 2021. According to him, under favourable circumstances, the main network can be presented in November of this year, but there are certain difficulties in this.
Schoedon explained that before launching ETH 2.0, all of its clients must be brought to the same specifications. After that, the developer’s team needs to open a unified deposit contract so that users can transfer their assets from the old chain to the new one. Between these stages, developers also need additional time, so they could test all aspects of the new system.
As it usually happens, there’s going to be two parallel blockchains as a result of the hard fork. The first one, ETH1, will continue to work using an old protocol, while the update will be implemented on ETH2. Users will be able to transfer their coins from the old blockchain to the new one, but not vice versa. The appearance of sharding will allow developers to move to phase 1.5 — during this phase, ETH1 will merge with ETH2, becoming one of the 64 “shards” of the updated blockchain. In the second phase, smart contracts become available on ETH2, which can be considered the full start of its economic activity.

And what are expectations?

Updating the Ethereum network will increase its technical capabilities, namely, it will speed up and reduce the cost of transactions, as well as make the blockchain less vulnerable for centralization process.
Currently, the absolute majority of decentralized finance projects are developed using the Ethereum platform. The Ethereum 2.0 release will probably attract even more partners who will use the blockchain for their projects.
Ryan Watkins, Messari Analysis company’s researcher, highly values the importance of updating.
“ETH 2.0 is a much stronger catalyst than the Bitcoin halving simply because it’s an uncertain and fundamental change.” — Ryan Watkins wrote on his Twitter account
And the part about uncertainty is hard to disagree with. Of course, there are some concerns about the bright Ethereum future. The coming hard fork carries with it potential negative consequences. For example, after switching to the PoS algorithm, the US Securities and Exchange Commission (SEC) may well admit Ethereum as a security, which will lead to legal complications similar to those faced by Pavel Durov when trying to launch his TON blockchain platform.
For now, ETH is the most popular coin for mining at home, and most of these miners will probably just leave the network.
There is also a risk that the price of Ethereum may fall. To receive passive income for storing ETH, the user will not only need to have 32 coins but also block them through a special transaction. They will not be able to withdraw these blocked funds immediately. As stated in the project roadmap, the cryptocurrency withdrawal process will take at least 18 hours. This could take even more time if many users request the return of tokens at the same time. Thus, if ETH falls in price, it will be impossible to sell it immediately, and there is a risk of losing some capital and all the income received from stacking.
Nevertheless, investors are mostly optimistic — the volume of Ethereum options on the Deribit exchange has grown to a historical high, which indicates confidence in the future of Ethereum project. The ETH price is also growing, having overcome the consequences of the March collapse of cryptocurrencies.
Most experts agree that Ethereum price will grow after the update. On the one hand, the altcoin will become more expensive, as it will become a more attractive investment. On the other hand, the offer will decrease, as users will start transferring coins from the first version of the network to the second, to block them for passive income.

Concerns for "wasting electricity" on POW system may be over-blown. Every 4 years the coinbase halves. As time passes, every $1 used for electricity more closely approaches 100 economic transactions. On Bitcoin Cash at least. That is a BARGAIN!

As time passes more of the miner profits come from transactions instead of coinbase. So when coinbase is almost nothing, then $1 that miner spends for electricity is derived from 100 economic transactions (assuming a cheap tx blockchain like Bitcoin Cash).
Imagine the power that 100 transactions is bringing to the economy at the cost of $1 of electricity....boggles the mind! This might be the greatest deal in human history.
Assuming $0.01 fee per tx. Go Bitcoin Cash!

Why The Actual Cost Of Mining Bitcoin Can Leave It Vulnerable To A Deep Correction

In early 2020, researchers predicted the cost to mine Bitcoin will be at around $12,000 to $15,000 after the block reward halving in May. But, it is now much cheaper to mine BTC than the initial estimates. The low breakeven price to mine Bitcoin may leave it vulnerable to a correction.
Bitcoin has become more affordable to mine in recent weeks due to two main factors: difficulty adjustments and cheaper electricity in Sichuan, China due to the rainy season.
A low breakeven price of Bitcoin can raise the probability of a price pullback because miners have more incentive to sell BTC, which may increase selling pressure in the short-term.
On May 11, the third block reward halving in the history of Bitcoin occurred. A halving is activated every four years and it decreases the amount of BTC miners can generate by half.
A halving is necessary for Bitcoin because the dominant cryptocurrency has a fixed supply of 21 million BTC. As it reaches towards its maximum supply, the rate of producing BTC decreases to provide balance.
But, when a halving happens, miners experience a near-50% cut in their revenues overnight. As such, it typically leads over-leveraged miners to capitulate or stop operating due to high costs.
When fewer miners are mining BTC, the Bitcoin network automatically adjusts the difficulty to mine BTC.
Since Bitcoin miners use computing power to mine, big mining centers can usually mine more BTC after the difficulty adjusts.
The Bitcoin blockchain network saw two difficulty adjustments in the past three months, allowing major miners to see higher revenues in the short-term.
Here’s where the extra surplus of BTC becomes a problem.
According to several Chinese miners based in Sichuan, China, electricity in the region costs around $0.04 per kilowatt-hour.
Due to the rainy season and the abundance of hydropower plants in the area, mining industry executives state that large mining centers in China can often negotiate lower electricity prices.
With $0.04/kwh, miners based in China said that the breakeven cost to mine Bitcoin hovers in the $5,000 to $6,000 range.
Even individual miners running commercial mining equipment like the Antminer S9 is operating at a breakeven cost of $8,206.
“To be completely accurate: Given current difficulty, 0.04$/kWh and S9 running custom firmware bringing it down to 71W per TH efficiency. The cost to mine 1 BTC is 8206.64$. Meaning its still profitable,” one miner said.
Considering the cost to mine Bitcoin for both big mining centers and individual miners can range in between $5,000 and $8,500, miners have more incentive to sell to cover operational costs rather than to hold onto the BTC they mine.
According to data from ByteTree, Bitcoin miners did not sell much Bitcoin in the past week. Around 6,825 BTC were mined and 6,298 BTC were sold, leaving 527 BTC in net inventory.
In previous weeks, especially throughout March, on-chain data shows that miners sold more Bitcoin than their revenues.
Yet, the price of Bitcoin struggled to see a short-term rally despite the noticeable decline in selling pressure from miners since the start of June.
The relatively cheap cost to mine Bitcoin and the failure of BTC to break out of a multi-year resistance level at $10,500 with fewer sellers in the market raise the likelihood of another correction.

Antminer T19 May Not Affect Bitcoin Hash Rate but Keeps Bitmain Ahead

The Antminer T19 by Bitmain may not have a big impact on the Bitcoin network, and it comes out amid the firm’s internal and post-halving uncertainty.
Earlier this week, Chinese mining-hardware juggernaut Bitmain unveiled its new product, an application-specific integrated circuit called Antminer T19. The Bitcoin (BTC) mining unit is the latest to join the new generation of ASICs — state-of-the-art devices designed to mitigate increased mining difficulty by maximizing the terahashes-per-second output.
The Antminer T19 announcement comes amid the post-halving uncertainty and follows the company’s recent problems with its S17 units. So, can this new machine help Bitmain to reinforce its somewhat hobbled position in the mining sector?
T19: The cheaper S19
According to the official announcement, the Antminer T19 features a mining speed of 84 TH/s and a power efficiency of 37.5 joules per TH. The chips used in the new device are the same as those equipped in the Antminer S19 and S19 Pro, though it uses the new APW12 version of the power supply system that allows the device to start up faster.
Bitmain usually markets its Antminer T devices as the most cost-effective ones, while the S-series models are presented as the top of the line in terms of productivity for their respective generation, Johnson Xu — the head of research and analytics at Tokensight — explained to Cointelegraph. According to data from F2Pool, one of the largest Bitcoin mining pools, Antminer T19s can generate $3.97 of profit each day, while Antminer S19s and Antminer S19 Pros can earn $4.86 and $6.24, respectively, based on an average electricity cost of $0.05 per kilowatt-hour.
Antminer T19s, which consume 3,150 watts, are being sold for $1,749 per unit. Antminer S19 machines, on the other hand, cost $1,785 and consume 3,250 watts. Antminer S19 Pro devices, the most efficient of three, are considerably more expensive and go for $2,407. The reason Bitmain is producing another model for the 19 series is due to what is known as "binning" chips, Marc Fresa — the founder of mining firmware company Asic.to — explained to Cointelegraph:
“When chips are designed they are meant to achieve specific performance levels. Chips that fail to hit their target numbers, such as not achieving the power standards or their thermal output, are often ‘Binned.’ Instead of throwing these chips in the garbage bin, these chips are resold into another unit with a lower performance level. In the case of Bitmain S19 chips that don’t make the cutoff are then sold in the T19 for cheaper since they do not perform as well as the counterpart.” The rollout of a new model “has nothing to do with the fact that machines are not selling well,” Fresa went on to argue, citing the post-halving uncertainty: “The biggest reason machines probably are not selling as well as manufacturers would like is because we are on a bit of a tipping point; The halving just happened, the price can go anyway and the difficulty is continuing to drop.” Product diversification is a common strategy for mining hardware producers, given that customers tend to aim for different specifications, Kristy-Leigh Minehan, a consultant and the former chief technology officer of Genesis Mining, told Cointelegraph:
“ASICs don’t really allow for one model as consumers expect a certain performance level from a machine, and unfortunately silicon is not a perfect process — many times you’ll get a batch that performs better or worse than projected due to the nature of the materials. Thus, you end up with 5–10 different model numbers.” It is not yet clear how efficient the 19-series devices are because they have not shipped at scale, as Leo Zhang, the founder of Anicca Research, summed up in a conversation with Cointelegraph. The first batch of S19 units reportedly shipped out around May 12, while the T19 shipments will start between June 21 and June 30. It is also worth noting that, at this time, Bitmain only sells up to two T19 miners per user “to prevent hoarding.”
Hardware problems and competitors
The latest generation of Bitmain ASICs follows the release of the S17 units, which have received mostly mixed-to-negative reviews in the community. In early May, Arseniy Grusha, the co-founder of crypto consulting and mining firm Wattum, created a Telegram group for consumers unsatisfied with the S17 units they purchased from Bitmain. As Grusha explained to Cointelegraph at the time, out of the 420 Antminer S17+ devices his company bought, roughly 30%, or around 130 machines, turned out to be bad units.
Similarly, Samson Mow, the chief strategy officer of blockchain infrastructure firm Blockstream, tweeted earlier in April that Bitmain customers have a 20%–30% failure rate with Antminer S17 and T17 units. “The Antminer 17 series is generally considered not great,” added Zhang. He additionally noted that Chinese hardware company and competitor Micro BT has been stepping on Bitmain’s toes lately with the release of its highly productive M30 series, which prompted Bitmain to step up its efforts:
“Whatsminer gained significant market share in the past two years. According to their COO, in 2019 MicroBT sold ~35% of the network hashrate. Needless to say Bitmain is under a lot of pressure both from competitors and internal politics. They have been working on the 19 series for a while. The specs and price look very attractive.” Minehan confirmed that MicroBT has been gaining traction on the market, but refrained from saying that Bitmain is losing market share as a result: “I think MicroBT is offering option and bringing in new participants, and giving farms a choice. Most farms will have both Bitmain and MicroBT side by side, rather than exclusively host one manufacturer.”
“I would say that MicroBT has taken up the existing market share that Canaan has left,” she added, referring to another China-based mining player that recently reported a net loss of $5.6 million in the first quarter of 2020 and cut the price of its mining hardware by up to 50%.
Indeed, some large-scale operations seem to be diversifying their equipment with MicroBT units. Earlier this week, United States mining firm Marathon Patent Group announced that it had installed 700 Whatsminer M30S+ ASICs produced by MicroBT. However, it is also reportedly waiting for a delivery of 1,160 Antminer S19 Pro units produced by Bitmain, meaning that it also remains loyal to the current market leader.
Will the hash rate be affected?
Bitcoin’s hash rate plummeted 30% soon after the halving occurred as much of the older generation equipment became unprofitable due to the increased mining difficulty. That spurred miners to reshuffle, upgrading their current rigs and selling older machines to places where electricity is cheaper — meaning that some of them had to temporarily unplug.
The situation has stabilized since, with the hash rate fluctuating around 100 TH/s for the past few days. Some experts attribute that to the start of the wet season in Sichuan, a southwest Chinese province where miners take advantage of low hydroelectricity prices between May and October.
The arrival of the new generation of ASICs is expected to drive the hash rate even higher, at least once upgraded units become widely available. So, will the newly revealed T19 model make any impact on the state of the network?
Experts agree that it won’t affect the hash rate to a major degree, as it’s a lower output model compared with the S19 series and MicroBT’s M30 series. Minehan said she doesn’t expect the T19 model “to have a huge impact that’s an immediate cause of concern,” as “most likely this is a run of <3500 units of a particular bin quality.” Similarly, Mark D’Aria, the CEO of crypto consulting firm Bitpro, told Cointelegraph:
“There isn’t a strong reason to expect the new model to significantly affect the hashrate. It might be a slightly more compelling option to a miner with extraordinarily inexpensive electricity, but otherwise they likely would have just purchased an S19 instead.” Bitmain continues to hold leadership despite internal struggle
At the end of the day, manufacturers are always in an arms race, and mining machines are simply commodity products, Zhang argued in a conversation with Cointelegraph:
“Besides price, performance, and failure rate, there are not many factors that can help a manufacturer differentiate from the others. The relentless competition led to where we are today.” According to Zhang, as the iteration rate naturally slows down in the future, there will be more facilities using “creative thermal design such as immersion cooling,” hoping to maximize the mining efficiency beyond just using most powerful machines.
As for now, Bitmain remains the leader of the mining race, despite having to deal with the largely defunct 17 series and an intensifying power struggle between its two co-founders, Jihan Wu and Micree Zhan, which recently resulted in reports of a street brawl.
“Due to its recent internal issues, Bitmain is facing challenges to keep its strong position in the future thus they started to look at other things to expand its industry influences,” Xu told Cointelegraph. He added that Bitmain “will still dominate the industry position in the near future due to its network effect,” although its current problems might allow competitors such as MicroBT to catch up.
Earlier this week, the power struggle inside Bitmain intensified even further as Micree Zhan, an ousted executive of the mining titan, reportedly led a group of private guards to overtake the company’s office in Beijing.
Meanwhile, Bitmain continues to expand its operations. Last week, the mining company revealed it was extending its “Ant Training Academy” certification program to North America, with the first courses set to launch in the fall. As such, Bitmain seems to be doubling down on the U.S.-based mining sector, which has been growing recently. The Beijing-based company already operates what it classifies as “the world’s largest” mining facility in Rockdale, Texas, which has a planned capacity of 50 megawatts that can later be expanded to 300 megawatts.

Great! After a decade it probably synced and now you are wondering how to get coins? Bad news: You don't get coins by running your wallet, even running it as a full node. Check what a full node is here.
Maybe you thought so, because you saw a very old screenshot of a wallet, like this (Version 1.2). This version had a "Dig" tab where you can enter your mining configuration. The current version doesn't have this anymore, probably because it doesn't make sense anymore.

You downloaded a GPU/CPU miner

Nice! You did it, even your antivirus system probably went postal and you started covering all your webcams... But here is the bad news again: Since people are using ASIC miners, you just can't compete with your CPU hardware anymore. Even with your more advanced GPU you will have a hard time. The hashrate is too high for a desktop PC to compete with them. The blocks should be mined every 1 minute (or so) and that's causing the difficulty to go up - and we are out... So definitly check what is your hashrate while you are mining, you would need about 1.5 MH/s to make 1 Doge in 24 hours!

Mining Doge

Let us start with a quote:
"Dogecoin Core 1.8 introduces AuxPoW from block 371,337. AuxPoW is a technology which enables miners to submit work done while mining other coins, as work on the Dogecoin block chain."
- langerhans
What does this mean? You could waste your hashrate only on the Dogecoin chain, probably find never a block, but when, you only receive about 10.000 Dogecoins, currently worth about $25. Or you could apply your hashrate to LTC and Doge (and probably even more) at the same time. Your change of solving the block (finding the nonce) is your hashrate divided by the hashrat in sum - and this is about the same for Doge and LTC. This means you will always want to submit your work to all chains available!

Mining solo versus pool

So let's face it - mining solo won't get you anywhere, so let's mine on a pool! If you have a really bad Hashrate, please consider that: Often you need about $1 or $2 worth of crypto to receive a payout (without fees). This means, you have to get there. With 100 MH/s on prohashing, it takes about 6 days, running 24/7 to get to that threshold. Now you can do the math... 1 MH/s = 1000 KH/s, if you are below 1 MH/s, you probably won't have fun.

Buying an ASIC

You found an old BTC USB-miner with 24 GH/s (1 GH/s = 1000 MH/s) for $80 bucks - next stop lambo!? Sorry, bad news again, this hashrate is for SHA-256! If you want to mine LTC/Doge you will need a miner using scrypt with quite lower numbers on the hashrate per second, so don't fall for that. Often when you have a big miner (= also loud), you get more Hashrate per $ spent on the miner, but most will still run on a operational loss, because the electricity is too expensive and the miners will be outdated soon again. Leading me to my next point...

Making profit

You won't make money running your miner. Just do the math: What if you would have bougth a miner 1 year ago? Substract costs for electricity and then compare to: What if you just have bought coins. In most cases you would have a greater profit by just buying coins, maybe even with a "stable" coin like Doges.

Cloud Mining

Okay, this was a lot of text and you are still on the hook? Maybe you are desperated enough to invest in some cloud mining contract... But this isn't a good idea either, because most of such contracts are scams based on a ponzi scheme. You often can spot them easy, because they guarantee way to high profits, or they fake payouts that never happened, etc.
Just a thought: If someone in a subway says to you: Give me $1 and lets meet in one year, right here and I give you $54,211,841, you wouldn't trust him and if some mining contract says they will give you 5% a day it is basically the same.
Also rember the merged mining part. Nobody would offer you to mine Doges, they would offer you to buy a hashrate for scrypt that will apply on multiple chains.

Alternative coins

Maybe try to mine a coin where you don't have ASICs yet, like Monero and exchange them to Doge. If somebody already tried this - feel free to add your thoughts!

Folding at Home (Doge)

Some people say folding at home (FAH - https://www.dogecoinfah.com/) still the best. I just installed the tool and it says I would make 69.852 points a day, running on medium power what equates to 8 Doges. It is easy, it was fun, but it isn't much.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

For a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
https://preview.redd.it/t1j6anf8f3151.png?width=1601&format=png&auto=webp&s=33bd141d8f2136a6f32739c8cdc7aae2e04cbc47

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.

The One Thing EVERYONE Must Know About the Dev Funding Plan: IT'S COMPLETELY FREE.

sigh I get so tired of having to stop working to put out a post explaining issues. If anyone else wants to join in I could use help. (actually I've seen Jonald F. do this before too, so thanks JF!)
Things are bad when even developers don't understand what's going on. So I'll try to clearly explain an important point on the Dev Funding Plan (DFP from now on) for the community: it's completely free. Yet we still get panicked posts saying Please Save Us from the TAX!!! Somebody Help!
You may be for or against the DFP, but either way please at least understand what you're forming an opinion on.
Let's start from the beginning. We know Bitcoin works on blocks and block coin rewards. The block reward, which started at 50 coins per block, and cuts in half approximately every 4 years, serves two purposes: it's a fair way to bring coins into circulation, but more importantly it provides security for the network.
For simplicity, please think of "security" as being measured in power bars. When the network first started, with just Satoshi and Hal Finney, there was 1 power bar. This power bar was made up of the electricity their combined computer hardware used to find blocks. They were the first miners. Bitcoin uses a difficulty level to adjust how hard or easy it is to find blocks. This level is important for a key reason: we want the inflation rate of coins (how fast they come into circulation) to stay about the same, regardless how many miners (computing power) suddenly comes online. If the difficulty is set at super easy, but suddenly a super computer comes online that computer can gobble up thousands of coins in minutes if not seconds, creating massive rapid inflation. So the first thing to understand is that due to the Difficulty Level Adjustment the rate of coins coming into circulation will always stay about the same, regardless how many miners join or leave the network.
Getting back to power bars. So the point of Bitcoin is there is no center, no fixed authority. The problem is we still need a decision made about which chain is valid. This is where proof-of-work comes in. Satoshi's fairly brilliant solution to a consensus decision, with no leader, was to simply look for the longest chain (technically the chain with most hashing work). The reasoning was: as there are far more ordinary people than there are governments and dictators a Bitcoin supported by the all the world's people should always be able to muster more hashrate than even rich governments.
So Bitcoin began and people saw the brilliance: even with a weak power bar level of 1 (a couple computers), Bitcoin was safe from 51% attacks and attacking govs competing for control of the chain because a super low hashrate meant Bitcoin wasn't popular and govs wouldn't bother paying attention. By the time Bitcoin was big enough for govs to worry about attacking it should also have so many participants the power bar level would be far higher, providing strong defense.
Let's say the ideal power bar level is 50,000. At this level no government on earth has enough resources to beat the grassroots network. We hear people brag about how much security BTC has. However, the marketcap for all of BTC is about $160B. Countries like the U.S. and China have GDP measured in many trillions; a trillion is 1,000 billion. Does 160B really seem untouchable? For numeric comparison the main U.S. federal food assistance program cost the government $70B in 2016, representing about 2% of the budget. So the entirety of the BTC market cap is about twice the size of one welfare program, representing 2% of the overall budget. Where should we place the current security power bars if we want guaranteed safety from a determined U.S. gov? If 50,000 is guaranteed safe we're far from it. I'd say BTC is more like 5,000. That's still pretty decent.
Of course, BCH split from BTC... and didn't carry over all the miners and accompanying security. That's not an immediate concern because if BTC isn't on government's radar yet BCH sure isn't. However, that doesn't mean BCH doesn't need security from hostile forces. It's still a valuable network and needs defenses. Where would we put power bars for BCH? If BTC is 5,000 and BCH only has 3% of that hashrate then BCH has just 150. That's it.
How the Developer Funding Plan Works
Back to the DFP. What this says is as a community we agree to break off a piece of the block reward and instead of giving 100% to miners we give a small percent to developers. If each block is 10 coins and the price is $300 then winning a block means winning $3,000. Of course that's not all profit because miners have electricity and other expenses to pay before calculating profit. So if we reduce the portion of the miner reward by 10% so they get just 9 coins per block yet the price stays the same what happens? It means miners receive $2,700 for the same effort. We've just made it more expensive to mine BCH from the point of view of miners. What would any miner then rationally do? Seek profitability elsewhere if available. Suddenly BTC SHA256 hashing looks slightly more attractive so they'll go there. Hashrate leaves BCH and goes to BTC, but the key important point is BOTH chains have a difficulty adjustment algorithm which adjusts to account for rising or lowering miners overall, which keeps the coin inflation rate steady. This means BTC total hashrate rises (more miners compete for BTC) and its Difficulty Level rises accordingly, so the same rate of BTC pumps out; on BCH total hashrate falls (less miners compete for BCH) and its Difficulty falls, so the same rate of BCH pumps out. Inflation remains about the same on both coins so the price of both coins doesn't change any, beyond what it normally does based on news/events etc.
So what difference is there? The difference is total network security. Hashrate totals have changed. BTC gains more miner securing hashrate while BCH loses it. So BTC goes from 5,000 to say 5,100 power bars. BCH goes from about 150 to 140.
Does any of that matter in the grand scheme of things? Not in the slightest. Part of the reason is due to our emergency circumstances with BCH we had to rework our security model. Our primary defense is an idea I came up with, which BitcoinABC implemented, saying it's not sheer hashpower that dictates what chain we follow. We won't replace a chain we're working on if a new one suddenly appears if it means changing more than 10 blocks deep of history. This prevents all the threatening hashrate hanging over our heads from mining a secret chain and creating havoc unleashing it causing 10+ confimed txs to be undone, while exchanges, gambling sites etc. have long since paid out real world money.
Switching $6M worth of block rewards from mining to devs just means we lose a bit of hashrate security, while we gain those funds for development. Nothing more. Nobody holding BCH pays in the form of inflation or any other way. It costs literally NOTHING BECAUSE The block reward is ALREADY ALLOCATED. It will EITHER go 100% to mining security if we do nothing, or go to both miners and devs if the plan is put into effect. Hopefully this helps.
:)
TL;DR: we switch security which we don't really need, for developer funding which we do.

Week 61  Mining Payouts 5/14/20 Does Bitcoin Have Intrinsic Value Based On The Cost Of Mining - D-Central Week 60  Mining Payouts 5/7/20 Just how much energy is Bitcoin using? Week 65  Mining Payouts 6/15/20

Price – How much does the bitcoin miner cost? Cheap mining hardware will mine less bitcoins, which is why efficiency and electricity usage are important. The fastest and more efficient mining hardware is going to cost more. Don’t try to buy a miner based on only price or only hash rate. The best ASIC miner is the most efficient bitcoin miner. On January 22, 2019, the Bitcoin Energy Index was estimating that 100% of miner revenues ($2.3B) were actually spent on electricity costs. This can happen after a significant drop in mining revenues where mining becomes generally unprofitable. The Elite Fixtures report looked at the costs to mine a single bitcoin US:BTCUSD in 115 different countries based on average electricity rates according to local government data, utility company Bitcoin Mining cost is different for every single miner that usually depends on location, electricity cost, bitcoin mining hardware device type used as well as maintenance cost of hardware. It is not possible to find the Bitcoin mining cost variation between locations as there is no single source that will do, a lot of mining operations are not The map above shows a very rough estimate of the current electricity costs of mining one Bitcoin by country around the world.. Based on our research, Kuwait is the cheapest country in the world to mine Bitcoins while the Solomon Islands would be the most expensive. Overall, Bitcoin’s total electricity consumption is huge. In November last year we reported that Bitcoin Mining Now Consuming
