Transaction Malleability and Coinkite (official post)

Transaction Malleability and Coinkite (official post) submitted by rnvk to Bitcoin [link] [comments]

Why is Peter Todd wrecking Zeroconf security? Because he is being paid by Big Bitcoin Business.

At the Amsterdam Bitcoin Conference I spent time following Peter and his little circle of friends and business partners. I'm new to Bitcoin so it took me until now to put two and two together and understand what was really going on, but hear me out. Peter spent a lot of time talking to Lawrence Nahum who is the guy behind GreenAddress. On the first or second day they went out to dinner after the days talks were done and went out to a nice little open-air restaurant with a bunch of people from Mastercoin. I sat at a table behind them and could hear their discussions, which including GreenAdddress's transaction confirmation guarantees, and also, an agreement for Peter to do consulting work for GreenAddress. What really stood out to me was the offer to help "shape the Bitcoin ecosystem" in ways beneficial to them. Later in the conference I also overheard a similar deal between Peter and someone, I didn't catch their name, in Coinbase branded apparel. And of course as everyone knows CoinKite hired Peter to be their "Chief Naysayer" during that conference too.
What's in common with all these companies? They're all in the dangerous business of holding other peoples' Bitcoins and GreenAddress and Coinbase both offer for-profit and centralized solutions to guarantee unconfirmed transactions. I'm sure CoinKite will be doing that soon too.
It's obvious why Peter is spending all that time and energy spreading FUD about how insecure unconfirmed transactions are. GreenAddress has been spreading their own FUD. Peter has even been trying to bribe miners to switch to his so called "replace-by-fee", which is really just an attack on secure zeroconf transactions, saying some un-named "site" paid him too. Who might that be? GreenAddress, Coinbase, CoinKite? It's not hard to figure out.
Peter sure seems quite happy to attack and hold back Bitcoin whenever it suits him for the sake of his Big Bitcoin Business contracts. It's not just unconfirmed transactions either. He's been shilling for AppCoins which dump garbage into the blockchain for the sake of pump-and-dump schemes like Mastercoin and Counterparty. (quite the about face from his supposed anti-blockchain bloat positions before) Or look at his weirdly passionate opposition to a simple feature, getutxos, that's needed for Mike Hearn's decentralized fundraising platform Lighthouse. Where's that passion coming from? The heart? Or his salary from Mastercoin, Counterparty and Colored Coins? I'm sure Mastercoin wants the next Maidsafe to happen on their platform, run by and for the benefit of Mastercoin, not Hearn's truly decentralized alternative.
I agree with Peter that GHash.IO is a possible threat to Bitcoin, but what solution does he have? Getting rid of pools. His buddies at the totally discredited Hacking Distributed (remember selfish mining? yeah those guys) run with this FUD, trying to scare the Bitcoin community into making changes to get rid of pools. Sounds like a good idea right? But then I looked further into it and found out he had just been hanging out at CloudHashing. What does banning pools do to the little guy mining decentralized? It puts them out of business because they'll never find a block that's what. Just perfect for CloudHashing's "send us money and we'll run the miners" business model and also GHash.IO's.
Peter likes to talk the big talk about decentralization, but all I am seeing here is paid shilling for the benefit of Big Bitcoin Business.

Bitcoin dev meeting in layman's terms (2015-10-8)

Once again my attempt to summarize and explain the weekly bitcoin developer meeting in layman's terms. Link to last weeks summarization
Disclaimer
Please bare in mind I'm not a developer and I'd have problems coding "hello world!", so some things might be incorrect or plain wrong. Like any other write-up it likely contains personal biases, although I try to stay as neutral as I can. There are no decisions being made in these meetings, so if I say "everyone agrees" this means everyone present in the meeting, that's not consensus, but since a fair amount of devs are present it's a good representation. The dev IRC and mailinglist are for bitcoin development purposes. If you have not contributed actual code to a bitcoin-implementation, this is probably not the place you want to reach out to. There are many places to discuss things that the developers read, including this sub-reddit.
link to this week logs link to meeting minutes
Main topics discussed this week where:
Mempool limiting: chain limits Low-S change CLTV & CSV review Creation of bitcoin discuss mailing list
off-topic but important notice
This issue has made most JS bitcoin software vulnerable to generating incorrect public keys. "This is an ecosystem threat with the potential to cause millions of dollars in losses that needs higher visibility; though it's not a bitcoin core / bitcoin network issue. Common, critical, JS code is broken that may cause the generation of incorrect pubkeys (among other issues). Anyone who cares for a JS implementation should read that PR."
Mempool limiting: chain limits
(c/p from last week) Chain in this context means connected transactions. When you send a transaction that depends on another transaction that has yet to be confirmed we talk about a chain of transactions. Miners ideally take the whole chain into account instead of just every single transaction (although that's not widely implemented afaik). So while a single transaction might not have a sufficient fee, a depending transaction could have a high enough fee to make it worthwhile to mine both. This is commonly known as child-pays-for-parent. Since you can make these chains very big it's possible to clog up the mempool this way. The first unconfirmed transaction is called the ancestor and the transactions depending on it the descendants. The total amount of transactions is reffered to as "packages".
As said in "Chain limits" last week Morcos did write a proposal about lowering the default limits for transaction-chains. 2 use cases came up which are currently in use or happened before: As example: someone buys bitcoin from a website and can spend those bitcoin in the marketplace of the same website without waiting for confirmation in order to improve the bitcoin user-experience. This leaves a sequential transaction chain. They don't need to chain more than 5 transactions deep for this, and it falls within the proposed limits. What's not within the proposed limits is the chain of +/- 100 transactions a company had during the spam-attacks. These where simply increased activities by end-users while not enough UTXO's where available (3 to be precise)(UTXO: unspent transaction output, an output that can be used as input for a new transaction). Notably this is with the best practices of using confirmed transactions first. Ways this can be solved from the company's end is to have more UTXO's available before hand, bundling transactions (which requires delaying customer's request) or using replace-by-fee to add payees (which saves blockchain space, is cheaper in fees and gets transactions through quicker, but is not widely deployed by miners atm). Bare in mind these proposals are for default values for the memorypool, not in any way hard limits.
Sense of urgency. Quoting sipa: "my mempool is 2.5G... we better get some solution!" Current attack analysis assumes child-pays-for-parent mining, it should probably be done again without. Higher limits on number of transactions increase attack-vectors. Proposed number of transactions gets some push-back, total size limit not. Mixing default values (for example having a 50% of a 10/10 limit and 50% of a 100/100 limit) wastes bandwidth while there are too many factors that limit utility of long chains as well. 25 transaction limit ought to be enough for everyone (for now).
Review & test Limit mempool by throwing away the cheapest txn and setting min relay fee to it Provide support for Lower default limits for tx chains aka convince people 25 should be enough.
Low-S change
This is in regards to the recent malleability attack. Which is caused by a value 'S' in the ECDSA signature which can be 2 values, a high and low value and still be valid. Resulting in different transaction id's. more info A solution for this is to require nodes to have the "low-s" encoding for signatures. Downside is that it will block most transactions made by sufficiently out of date software (+/- pre-march 2014) This does not replace the need for BIP62, it only eliminates the cheap DOS attack.
95% of transactions already confirm to this, and more fixes have been applied since. BlueMatt has a node which several people are running that auto-malleates to low-s transactions. Questions whether we release it ASAP or wait for the next release and get it to a couple of miners in the meantime (possibly with auto-lowS-malleating)
Contact miners about "Test LowS in standardness, removes nuisance malleability vector" Release scheduled for the end of the month, together with likely check-lock-time-verify and possibly check-sequence-verfiy.
CLTV & CSV backport review
CLTV: checkLockTimeVerify CSV: checkSequenceVerify Both new time-related OP-codes. Been discussed heavily last week.
Concerns whether CSV will be ready enough for release later this month. There's no clarity on how things look when all 3 time related pull-requests are merged. There's a number of people still reviewing the pull-requests. Uncertainty and confusion about whether the semantics are final or not (in regards to using bits from nSequence). nSequence are 4 bytes intended for sequencing time-locked transactions, but this never got used. Now these bytes are being repurposed for a mixture of things. Currently the plan is: " bits 0..15 are the relative locktime, bit 30 determines units (0: height, 1: time w/ 512s granularity), and bit 31 toggles BIP 68 (0: on, 1: off). bits 16..29 are masked off and can take any value."
Clarification from maaku regarding nSequence for BIP68. (after the meeting he explained he was waiting for opinions, but not enough people seemed to know the issue at hand) Continue review of pull requests 6312, 6564 and 6566
Creation of bitcoin discuss mailing list
The bitcoin-dev mailing list is intented for technical discussions only. There's things that don't belong there but need to be discussed anyway. Now this is done in bitcoin-dev, but the volume of this is getting too big. There's recently also an influx of really inappropriate posts, level kindergarden.
No clarity about who are the moderators. Next week there'll be a bitcoin-discuss list created. Decisions are needed as to who'll become the moderators for that and bitcoin-dev. Decisions are needed as to what will be the list and moderation policies.
The bitcoin-discuss list will be created as well as a simple website listing all the lists and corresponding policies. A meeting is scheduled on monday to discuss the moderation and policies of said lists.

List of relevant parties we need to convince before we make the jump for bigger maxblocksize (repost from /r/bitcoin)

I think this might lead to a more constructive discussion here, considering how this place is much smaller, etc.
Now that the blocksize debate is back in the spotlight again, we all need to be reminded:
A hardfork is difficult to do under any circumstances.
That said, I don't believe that we'll need "100%" as some... ahem respectable folks in the community claim; Bitcoin is nothing without its economy and ecosystem, and what's essential to a fork is that it has the overwhelming majority of economic activity. Assuming the miners are not malicious, they will follow - and they will be onboard sooner and make the process less destructive if they see the overwhelming majority sooner.
Therefore, I propose we compile a checklist of major parties that we need to convince, in order to gain momentum on this. This list will become very useful once gavinandresen, mike_hearn and jgarzik finish their version of 0.11 / 0.11A XT for review.
I'll start with a list. The list is only a starter from my limited knowledge, so feel free to suggest changes:
Exchanges and Payment Processors
Major services/merchants that use a node
Note: Merchants that use payment processors will switch if payment processors are on board.
Major mining pools
Unfortunately Eligius can never be convinced. What a shame. =\
Wallets
Greenaddress is unlikely to be convinced.
Information website
While not essential to the ecosystem, will probably help a lot in getting the words out and hence building momentum.
Feel free to suggest additions/changes to the checklist. Let's get a roadmap so that we know what to aim for.

FAQ For Newcomers

August 9th, 2014: With the amount of projects that have been in constant development, this FAQ is somewhat out of date. While information about fundamentals of the coin remains the same and can be found here, there is much that has changed since then. In the meanwhile, please see the projects list here for a taste of the enormous development efforts of the BlackCoin community, and feel free to follow the subreddit to keep on track with new updates:
http://www.reddit.com/blackcoin/comments/27lz3h/blackcoin_projects_overview/
I created this as an initial draft of a FAQ for newcomers, feel free to recommend additions, corrections, removals, or changes.

How to obtain BlackCoin? [E]
Why BlackCoin instead of competing Proof of Stake coins? [F]

TL/DR Version: [H]

What is BlackCoin? [A]

BlackCoin is a cryptocurrency based on many of the ideas contained within the original Bitcoin protocol, but with a few very important changes. Being only a couple of months old, it is a relatively new currency, but has been experiencing rapid growth. It is already in the top 10 cryptocurrencies by market cap.

What separates BlackCoin from other cryptocurrencies? [B]

There are a few main advantages to BlackCoin that separate it from most other cryptocurrencies. To ensure a fair distribution of coins, BlackCoin was initially distributed through a Proof of Work phase, the same method that Bitcoin uses to generate coins and secure the network.
That period is now over, and BlackCoin has transitioned entirely to PoS, or Proof of Stake. This allows lightning fast confirmation times, which can average as fast as 10 seconds each. In comparison, bitcoin averages 10 minutes per confirmation and litecoin clocks in at 2.5 minutes. These faster confirmation times can provide an extraordinary advantage for merchant adoption, as well as greatly improving the user experience.

Why Proof of Stake? [C]

Proof of Work was a fantastic innovation that formed the backbone of the original Bitcoin protocol. The idea is that by solving a computationally intensive math problem, one can prove the effort they've done to secure the protocol. This is how a blockchain is generated, and the effort that is required to perform this computations contribute to a coin's scarcity and value.
However, proof of work eventually becomes an extraordinarily expensive system. To secure the bitcoin network at the current market value costs about $1.8 million dollars, every single day. Most of this money is leaving the system to pay for energy costs and specialized computer equipment, much of which is done by huge computer farms. Even worse, when the value of a bitcoin increases, so does this cost. The hypothetical "$10,000 bitcoin" would cost $13 billion per year to maintain. While some of this may be mitigated by a reward "halving" or two in 3-7 years time, decreasing this reward too substantially creates a potential security risk.
Proof of Stake solves this issue in a very elegant way. Rather than using computer power as a scarce resource to generate security, Proof of Stake uses the scarcity of the coin itself. A user may choose to "stake" his coins to generate the next block in the chain, and his chance of doing so is basically proportional to the weight of his own coins.
With Proof of Work, a user can attack a network if he holds 51% of the current computer power, but to do so with Proof of Stake, that user would need a large shares of the overall coins. Acquiring this number of coins would be very difficult and expensive, and such an individual would have little incentive to attack the network as this would hurt the value of his own coins. As such, a Proof of Stake system is secured through basic economic facts rather than mass computing power.
While this is still a very contentious issue, the superior environmental and economic efficients of Proof of Stake lead many here to believe that it could be the future of cryptocurrency.

What other reasons are there to pick up some BlackCoin? [D]

There are many interesting coins out there, but BlackCoin strives to be superior in all areas. The combination of Proof of Stake and fast transaction times allow BlackCoin to excel both as a long-term store of value and for day-to-day transactions, a rare combination. But the coin also has a strong community and a rapidly developing infrastructure.
The coin's original developer has continued to work on the coin and make sure new applications are secure, even going so far as to point out a potential vulnerability in a competing coin. There is a dedicated community manager and many others who have been helping BlackCoin to grow and thrive.
Further, there are many new and exciting projects going on with BlackCoin, and it can even be difficult to keep track of it all. The most famous of these projects is the Blackcoin mining pool (http://blackcoinpool.com/), which allows miners to group together to mine other Proof of Work coins and use the profits to purchase BlackCoin, allowing this value to be absorbed into the BlackCoin economy. But don't be confused - the coin wasn't built around the idea of the mining pool, it's just one of the many great community developments that have sprung up to support it.
There have been other major developments recently as well. BlackCoin was recently accepted to be part of CoinKite's point of sale system, a huge step which will make it easy for both physical and online merchants to accept BlackCoin. The Black Coin Card (www.blackcoincard.com) is another effort which will make it very simple for anyone to get started using BlackCoin. Even a press release was sent out today to spread the word about BlackCoin: http://www.prweb.com/releases/2014/04/prweb11772516.htm. The community brings more and more ideas each day to support and promote BlackCoin.

How to obtain BlackCoin? [E]

Just like any cryptocurrency at the moment, it can take a little effort to get started, but once you have some cryptocurrency to your name, it isn't too hard.
The best way at the moment to acquire BlackCoin would be to buy Bitcoin and send those to an exchange to convert to BlackCoin. BitStamp.net is one of the largest exchanges between USD and Bitcoin, while CoinBase is also an option for U.S. customers. Once you have bitcoin in your possession, you can convert them to BlackCoin pretty quickly. Just send them to an exchange like MintPal and you can buy them at the present market rate.
Unfortunately, it can be a bit slow to get Bitcoin with the above method, but it's probably the best. If you want greater speed, you could try localbitcoins.com or finding someone directly to trade with (perhaps another reddit user). However, you may pay a significant premium over the market rate this way (15%+) and have to be careful of scams.
For the miners out there, you can't mine BlackCoin directly, but you can join the BlackCoin pool which mines the most profitable coins and uses them to purchase BlackCoin. Another user made a video explaining how to get started here: http://www.reddit.com/blackcoin/comments/23dy88/a_video_on_how_to_get_set_up_for_new_members/ (But make sure you are pointed at the updated address, stratum+tcp://useast.blackcoinpool.com:3333 for scrypt as I write this, stratum+tcp://useast.blackcoinpool.com:4444 for SHA).

Why BlackCoin instead of competing Proof of Stake coins? [F]

Some way wonder why they should obtain BlackCoin when coins like NXT and Peercoin have been around longer. Of course, this is always up to an individual to decide, but I feel there are strong reasons to support BlackCoin instead.
I think PeerCoin was a great idea for a coin and was the original pioneer of the Proof of Stake/Proof of Work concept. It is still in a combination phase between the two, slowly transitioning to a pure proof of stake coin. But it is different in its goals from BlackCoin.
Peercoin was designed to be the sort of coin that you use as a store of value, but is also specifically designed not to be used for day to day transactions. It uses a slow transaction confirmation time of 10 minutes per block and a very high fixed fee rate for transactions at .01 PPC per kilobyte. It is intended to be more of a complementary coin to something like Bitcoin rather than a day to day currency.
NXT is another coin which is operating as completely Proof of Stake, but there are some important differences between the two coins. BlackCoin is currently about twice as fast as NXT in terms of average confirmation speed and was based on the original Bitcoin Protocol. In comparison, NXT was instead built on its own code base. This may allow some potential positive changes, but also means that NXT is more likely to introduce new bugs or exploits that were not a part of its tried-and-true predecessors.
But one of the biggest differences can be found in the initial coin distribution. BlackCoin was launched with a brief initial Proof of Work phase and no pre-mine. Although this phase is much shorter than the one implemented by Peercoin, it was announced a week in advance to give all miners and buyers an equal and fair opportunity to claim the coin. In contrast to this method, NXT was distributed based on Bitcoin payments to an account set up by the developer. The period for purchasing NXT was prematurely cut off 6 weeks early without any warning. See here for more information:
https://bitcointalk.org/index.php?topic=303898.msg3620944#msg3620944
Another important component of any cryptocurrency that truly cannot be understated is the community that supports, builds infrastructure for, and spreads awareness of the coin to increase both its utility and adoption rate. It is this very factor that I feel has played a major role in bringing Bitcoin to where it is today, with a multi-billion dollar market cap. While this is a largely subjective area, I feel that BlackCoin has one of the strongest communities, especially for a very young coin, with several new projects springing up every few days. Contrastingly, it appears that NXT has some schisms within the community as can be seen here, splitting into two different forums:
https://nextcoin.org/index.php/topic,4621.0.html
However, bear in mind that this is my own view on the situation as an outsider with limited involvement, and it is always best to do your own research if time permits.

Where can I talk to others about BlackCoin? [G]

There are a few places to talk about BlackCoin, news, and upcoming developments. First, where you are now, the reddit community has been growing very quickly:
http://www.reddit.com/blackcoin/ Make sure to check the sidebar for many more websites.
https://bitcointalk.org/index.php?topic=469640.0 This is the bitcointalk thread. This thread has historically had the most information of any forum, but it's quite a slog to read through. Worth checking up on if you don't want to miss anything though.
http://blackcointalk.com/ The "official" forums.

TL/DR Version: [H]

Blackcoin is a cryptocurrency. It's pretty new, but it's pretty great. It uses Proof of Stake, so it's efficient. It's also lightning fast. Bitcoin is slow and expensive to secure. Proof of Stake = the future. BlackCoin = the future. The community here is amazing. BlackCoinPool. BlackCoinCard. Press. Hype. CoinKite. New projects all the time. Don't get left in the dust. Blackcoin is the best in all areas. Speed, store of value, economics, efficiency, community, developers, got it all. Buy some.

List of relevant parties we need to convince before we make the jump for bigger maxblocksize

Now that the blocksize debate is back in the spotlight again, we all need to be reminded:
A hardfork is difficult to do under any circumstances.
That said, I don't believe that we'll need "100%" as some... ahem respectable folks in the community claim; Bitcoin is nothing without its economy and ecosystem, and what's essential to a fork is that it has the overwhelming majority of economic activity. Assuming the miners are not malicious, they will follow - and they will be onboard sooner and make the process less destructive if they see the overwhelming majority sooner.
Therefore, I propose we compile a checklist of major parties that we need to convince, in order to gain momentum on this. This list will become very useful once gavinandresen, mikehearn and jgarzik finish their version of 0.11 / 0.11A XT for review.
I'll start with a list. The list is only a starter from my limited knowledge, so feel free to suggest changes:
Exchanges and Payment Processors
Major services/merchants that use a node
Note: Merchants that use payment processors will switch if payment processors are on board.
Major mining pools
Unfortunately Eligius can never be convinced. What a shame. =\
Wallets
Greenaddress is unlikely to be convinced.
Information website
While not essential to the ecosystem, will probably help a lot in getting the words out and hence building momentum.
Feel free to suggest additions/changes to the checklist. Let's get a roadmap so that we know what to aim for.

New press release

Hey Blackcoiners...I thought we could use another press release so I came up with this. If anyone has any suggestions on how we could improve it, feel free. Also, we need to figure out the best way to get it out there.
BlackCoin Projects Taking Crypto-Currency to the Masses
BlackCoin leads the POS revolution in crypto-currency with unprecedented projects designed to reach the mainstream user.
With roughly two months since it's inception, BlackCoin has taken the crypto-currency world by storm. One of the first crypto-currencies to use the “proof of stake” system, BlackCoin has inspired many imitators in a short time. Despite the competition, BlackCoin has established itself as the most reliable currency in this class with an active and talented development team.
One reason that BlackCoin has separated itself from the pack is the unrivaled level of support and transparency from the development team. Leaders from the community recently participated in an online broadcast known as the “BlackCast.” This rare “unmasking” of the development team has helped build confidence and make the currency seem more professional. Many topics were discussed including: real world adoption of the currency, recent technological innovations, and promotional efforts.
The BlackCoin Pool is yet another innovation that has often been imitated but never successfully duplicated. While most crypto-currencies have mining pools, which use computers to solve complex algorithms, this results in an inflationary situation where many new coins are continually being created. BlackCoin uses a “multi-pool” which instead mines other virtual currencies and uses the proceeds to purchase BlackCoins for participants. This creates a steady stream of buying pressure in the market, which protects investors.
Recently, Version 2.0 of the BlackCoin Pool was released with much success. With improved performance, a built-from scratch interface, and new features, the pool has been popular within the mining community. As more miners join on a daily basis, the price support for the currency continues to expand.
Perhaps the most exciting development in recent days is the announcement that BlackCoin hired one of the leading tech PR agencies in the industry to promote the coin. Within a few days, the funds for the 90-day PR campaign were raised by the community, illustrating the level of involvement and confidence that it offers. The goal is to take BlackCoin into the mainstream and introduce it to new users. While Bitcoin has done a great job of illustrating the benefits of digital currency to millions of early adopters, BlackCoin aims to take that to the next level. With faster confirmation times, BlackCoin is the ideal choice for retail businesses who wish to offer their customers another way to pay.
With retail adoption on the horizon, BlackCoin has also partnered with a leading point of sale company called Coinkite. Coinkite makes it possible for consumers to load debit cards with BlackCoin, Litecoin, and Bitcoin. Their funds can then be spent at a growing roster of merchants from around the world. While other currencies typically take several minutes to confirm, BlackCoin transactions are typically completed in a few seconds, making it the ideal partner for Coinkite.
With so many projects on the horizon, it's easy to see why investors who missed out on the massive returns of Bitcoin are lining up to get involved with BlackCoin. The most popular method of purchasing the currency is by first purchasing Bitcoin and using that to buy BlackCoin on exchanges like Mintpal.com and Cryptsy.com. BlackCoin has also recently been added to the popular service Vault of Satoshi, which allows investors to buy directly with USD and other currencies. With huge returns and large volume, BlackCoin is attracting a new type of investor to the crypto-currency world. It's only a matter of time until it's accepted around the world, and investors who get in early reap the benefits.

More information on the Renewable Energy consumption of Bitcoin and the environmentally friendly alternative BlackCoin TL:DR

The amount of electricity required to maintain Bitcoin’s security is legendary. Its miners are scouring the globe searching for areas with the least-expensive electricity rates.
Unfortunately, these areas are where the least expensive renewable-energy resources exist in the world.
Links are provided below to the references to back up the claims made here. This document will be updated as needed based on your comments below.
It has been estimated that the additional electricity required to maintain BlackCoin’s cooperative minting network is much less than three one-thousands ( 3 / 1000 ) of what is now used to run an equivalent sized competitive Bitcoin mining network. Bitcoin’s current electrical consumption equipment arms race is gobbling up irreplaceable, renewable-energy resources in areas where they provide the less expensive renewable energy options bar none.
A recent study cited in the Wall Street Journal shows that the hash rate required for Bitcoin’s security last fall was one one-sixtieth (1 / 60) of what it is now. This hash rate inflation has been fueled by the tremendous profitability of large scale corporate mining operations, which have produced the mining technology arms race.
The largest known corporate Bitcoin mining operation is reported to be housed in a warehouse in Central Washington State where it takes advantage of the US’s lowest electricity rates bar none. The Spokane Review recently reported that a handful of additional competitors are now about to pop up.
Washington State is the leader in hydroelectric generation with 29% of the total national capacity according to the US Energy Information Administration. It is 10th in wind energy production. Nevertheless, the whole state still has the lowest residential electric rates in the country.
The New York Times reported on a similar setup in Iceland, which may have the least expensive electricity of any country in the world. It is powered by hydro and geothermal resources.
These corporate mining operations compete against each other for the right to enter the next ledger page into the Bitcoin blockchain. The startups that produce the otherwise useless mining equipment are forced to make outrageous claims for their latest drawing board designs to get
