Namecoin and the future of self-sovereign digital identity.

Namecoin's motto is "Bitcoin frees money – Namecoin frees DNS, identities, and other technologies."
biolizard89 has done fantastic work on the DNS part, but let's focus on the identity use case here. Recent events have convinced me that digital identity on the internet is broken. Consider:
What was true in 1993 when cartoonist Peter Steiner wrote "On the internet, nobody knows you are a dog" is still true today. The only difference is that identity is increasingly being weaponized using AI/ML so "On the internet, nobody knows you are a bot" would perhaps be more apt.
I read the following comment from a user on slashdot yesterday:
For the time being, you can assume that this comment was written by a human being. You can click on my username, look back at my history of posts, and go, "OK, here's a bunch of posts, by a person, going back more than a decade, to the TIME BEFORE BOTS." That is, before the first year of 2020.
Since humans are likely to adopt the majority opinion, bad actors find real value in being able to control the narrative online by surrounding the reader with manufactured opinions by bots that due to advances in ML/AI are quickly becoming indistinguishable from real users. This amounts to a Sybil attack on the minds of digital content consumers and poses major threat to the integrity of our social fabric.
Apart from the recent twitter incident used for scamming, nation states have been known to create massive bot armies of fake and hijacked user accounts to try and shift the narratives regarding the Hong Kong independence protests as well as national elections. This will only increase.
Currently, our digital identity is fragmented into silo's largely controlled by government institutions and mega corporations (FAANG) based on a "Trust us" model. As recent events have proven, this is a bad model and in dire need of improvement/replacement. IMHO we need to move from "Trust us" to a "Trust but verify" model where the user is in full control of their digital identity.
Namecoin can and should play an important role in building this 'web of trust composed of self-sovereign identities" as it is neutral (no owner), permissionless and secure (merge-mined). Daniel already developed a proof of concept with NameID but what can we do to take this further?
Personally I'd like to see users create Namecoin identities and link them to their social identities (e.g. Google, Facebook, Twitter, Reddit, etc). Then whenever they create content, they sign it with their private keys. This would allow a reader to verify the content was created by the user. Content verification would have stopped the recent twitter hack, because even if the hackers would have access to internal admin tools they would not have the private keys that the users produce valid content with. "Not your keys, not your content"
Content verification is only one part. Ideally a user would like to verify the integrity of the content creator as well. E.g. has this user passed human verification in any of the linked platforms? Does a trusted linked entity vouch for the reputation or integrity of this user (e.g. a government entity, financial entity or non-governmental organization?). This would require those platforms to allow linking of Namecoin ID with their Platform ID and allow lookup and signing of metadata provided by these platforms. (e.g. UserID Y is linked to PlatformID X and completed human verification on date Z, signed Twitter).
I image users could install an extension similar to uBlock or Privacy Badger that contains human curated blacklists and heuristics that operate on Namecoin entities to perform these checks and flag or filter content and users that fail integrity checks. This would allow a users to automatically weed out potential bots and trolls but keep full control of this process themselves, avoiding potential censorship if this task would fall on the platform owners themselves (something governments are pushing for).
We could take this even further and integrate Namecoin ID's in software and hardware devices as well. This could create chains of trust to verify the entire chain of content creation and manipulation to the final content posted on a social platform. Where every entity signs the resulting content. (E.g. camera -> photoshop -> twitter post)
Apart from signing content/messages (PGP style). Namecoin could perhaps also be used for managing identity tokens in a users 'Identity wallet'. Looking into my physical wallet this could include things like credit cards, insurance cards, government issued IDs, membership cards, transportation cards, key cards, etc. This could be done similar to 'colored coins' on Bitcoin. But would have to support some type of smart contract functionality to be useful (e.g. expiring tokens, etc).
I'm not a developer nor a technical writer, but I do think we need to think long and hard about how we can solve digital identity in a way that empowers users to trust and verify the content and identities of the peers we interact with online while also respecting privacy and preventing censorship by external parties. Namecoin could be the better path to building this web of trust, but given the current pace of AI/ML and the willingness by bad actors to weaponize it at scale against users interests we might not have much time. (Apologies for the rant!)

04-03 12:33 - 'Paul Le Roux' (self.Bitcoin) by /u/financeoptimum removed from /r/Bitcoin within 191-201min

'''
Paul Le Roux is a fascinating character, whose story entails drugs, gold, arms dealing, North Koreans, Iranians, elite-level encryption, Somali pirates, women...and more women.
Let's get into it...
Part 1/5 - The Early Years
Paul Le Roux was born on Christmas Eve, 1972, in Bulawayo, the second-largest city in what was then called—by the white minority that governed it, at least— Rhodesia.
In 1980, Robert Mugabe became prime minister of what would now be called Zimbabwe, ending minority white rule in the country.
Four years later, when Le Roux was 12, the family relocated to South Africa.
Not long after the move, in exchange for washing his father’s car, Le Roux was given his first computer. After that, a relation of Le Roux states that he became "completely anti-social.”
When Le Roux was 15 or 16, in the late 1980s, the local police raided the family home and arrested Paul for selling pornography. After that, Le Roux turned even more inward.
Although he was an excellent student, he despised the idea of learning Afrikaans, which was compulsory in South African schools, describing it as "a dead language" that he "didn't want to learn."
At 16, he dropped out of high school and decided to follow his interest in computers, taking a local programming course.
Family lore has it that after he spent one class explaining some technical fact to the teacher, he got a letter saying he no longer needed to attend. He then completed a year’s worth of material in eight weeks!
Accounts of Le Roux do indicate that he was exceptionally gifted, and people who worked with him described him as a genius.
After returning from a family holiday to Disneyland in the US, 17-year-old Le Roux decided to leave South Africa, and departed for the UK eight months later to work as a programmer.
He then moved from the UK to the US, where he lived in Virginia Beach.
After six months in the US, he followed his then-girlfriend Michelle to Australia in 1995. The couple married and Le Roux acquired Australian citizenship.
Le Roux frequented message boards and enjoyed trolling Australians. A typical post read:
"All of Australia could disappear into the Pacific and the only difference it would make to the World is the Americans would have one less pussy country to protect."
His posts caused outrage on the board - someone even changed their handle to fuck @ you.paul
Le Roux would later declare that his correspondents had fallen for his ploy:
"Australians are east to provoke and your postings (including 2 death threats, numerous flames, and one guy who swears he has my address & phone number) have provided me with hours of amusement."
Of course, Le Roux did more than just troll Australian message boards in this period...
Le Roux had started building E4M - Encryption for the Masses - in 1997, releasing it at the end of 1998.
Part 2/5 - The Turning Point
E4M allowed users to encrypt entire hard drives, and to conceal the existence of encrypted files (such that prying eyes wouldn't even know they were there).
According to Le Roux, the software was written from scratch, with thousands of hours going into its development and testing.
As well as this, in the [Politics section of the E4M website]1 , Le Roux published a sort of Manifesto, describing how "governments are increasingly relying on electronic data gathering" and how "Strong Encryption is the mechanism with which to combat these intrusions, preserve your rights, and guarantee your freedoms into the information age and beyond."
In the spirit of the open-source software movement in the late 90s, Le Roux released E4M for free and made the code available for other people to improve.
Therefore, with no income from his two years of labor, he was struggling financially. His marriage fell apart violently and the couple got divorced in 1999.
Le Roux first relocated to Hong Kong, then to Rotterdam in the Netherlands. He married a Dutch citizen named Lilian, and they had a child shortly after.
In 2000, in order to monetize E4M, Le Roux launched [SW Professionals]2 in 2000.
Based in South Africa, the company offered offshore programming, including E4M customization.
One of Le Roux's clients was an Italian telecoms engineer called Wilfried Hafner, who had corresponded with Le Roux for several years about E4M.
Hafner had founded a company to create a commercial encryption product that would combine some of the elements of E4M with another piece of software, Scramdisk. The new company would be called SecurStar, and its product would be called DriveCrypt.
Hafner hired Le Roux to build DriveCrypt's underlying engine.
At the time, Le Roux was desperate for money - he drove a beat up car and worked out of a Rotterdam apartment small enough that, on the phone, Hafner could often hear a baby crying in the background.
Hafner on the other hand was living in the South of France, and Le Roux openly coveted the kind of success that he imagined led to such a home. He told Hafner: "I am ambitious, I want to have all this."
However, in the middle of the development work for DriveCrypt, Hafner discovered that Le Roux was still working on E4M and had incorporated some of his work for SecurStar into his personal project. As a result, Hafner terminated Le Roux's contract.
By October 2002, SW Professionals was now defunct and Le Roux was openly soliciting for work on the alt.security.scramdisk forum.
It was around this time that Le Roux received some news that "shattered his whole world."
In 2002, he travelled to Zimbabwe to retrieve a copy of his birth certificate.
On the trip, his aunt and uncle pulled him aside to tell him the truth, and it was then that Le Roux found out he was adopted.
Although many family members had known for years, Le Roux’s parents had elected to keep him in the dark about it.
It was the "unknown" part that hurt him the most.
Shortly after, Le Roux appeared on an another set of message boards - he seemed to be launching some kind of moneymaking scheme that required opening a company based in the U.S.
In 2004, a group of anonymous developers did exactly what Hafner had feared: they released a new and powerful, free file-encryption program, called TrueCrypt, built on the code for E4M.
TrueCrypt combined security and convenience, giving users the ability to strongly encrypt files or entire disk drives while continuing to work with those files as they would a regular file on their computer.
Hafner and his SecurStar colleagues suspected that Le Roux was part of the TrueCrypt collective but couldn't prove it.
As we'll explore in Part 5, TrueCrypt is an interesting part of this story...
Part 3/5 - Money and Power
After Le Roux's departure from the encryption world, at least under his own name, he entered the Internet-pharmacy business.
What Le Roux did next was combine two of America's favourite past times, popping pills and online shopping, and the results were sensational. He turned over around $300MM in 4 years.
In 2007, Le Roux moved his family to Manila, where he would base his operations. He also had call centres in Israel. This was a brilliant move by Le Roux, as the authorities were not looking at Tel Aviv and Jerusalem as hot-spots for a large-scale organised crime operation...
Le Roux was moving serious volume during this time - his operation was once one of FedEx's largest customers.
A relative of Le Roux pointed to 2008 or 2009 as the point at which Le Roux snapped.
"I think the money got to him. I personally saw $100 million in his office in Makati. Cash, bud. It was fucking ridiculous. It was in wicker baskets lined up on the side of the wall in his office."
Le Roux's appetite only grew, and not just in the literal sense (he was known as the "Fat Man" in the Philippines): he wanted to be a different kind of businessman, a lord of the real underworld, not just the virtual one.
An Israeli associate of Le Roux tells how "Le Roux wanted to make more money, fast. Le Roux wanted to diversify, to be bigger. The only way to do that was illegal. He was living inside a movie, you could almost say."
As well as this, Le Roux was notorious for his sexual exploits - he once wrote to his cousin, "15-20 a week, sometimes 3 per night."
A former call centre employee tells how Le Roux approached him with an assignment, which at first he thought was collecting women for Le Roux to open a bar. However, that was not the reason, as Le Roux explained:
"I'm going to impregnate them, and build an army of kids."
Le Roux asked him to make a spreadsheet to track the women: their names, dress size, age, medical checkups. The operation was given top priority by Le Roux, who even sent his emissary to China to try to find women there.
It is rumoured that Le Roux has at least 11 children to 7 different women!
Le Roux's businesses expanded into logging, precious metals mining, gold smuggling, land deals, cocaine shipping, and arms dealing. These activities were spread across dozens of shell companies registered all over the world.
Of course, he needed to launder the money. Le Roux used paid muscle in Hong Kong to swap cash for gold bars, and then proceeded to stash the gold in warehouses in Hong Kong (this totalled around $50MM).
Speaking of paid muscle, Le Roux had plenty: ex-soldiers and mercenaries made sure any problems were dealt with force if necessary.
Le Roux was closest to ex-British soldier Dave Smith, who would act as the leader of the mercenaries and allow Le Roux to insulate himself and not have to deal with people. In fact, Le Roux once told Smith "I live vicariously through you."
However, things took a turn for the worse, at least from Dave Smith's perspective, as Smith stole $5MM worth of Gold from Le Roux.
Le Roux was furious. He then summoned Smith to his place in the country, and asked him to dig a hole as they needed to stash some gold. However, when he arrived, he was greeted by a South African hit-man. After the hit-man had finished shooting Smith, Le Roux then grabbed the gun and fired into Smith's corpse.
Le Roux then set about building an arms base in Somalia.
To achieve this, Le Roux called upon an ex-soldier from Europe, code-named 'Jack' to work for him on the ground in Somalia.
At sea, Jack had to bribe Somali pirates.
It was actually this activity in Somalia that landed Le Roux on the radar of the DEA, as he popped up in a UN Report on security in Somalia.
The DEA were now on his tail. Of course, his encryption skills came in handy - Le Roux's thick layers of encryption meant that the DEA needed someone on the inside...
Part 4/5 - "Well played gentlemen, well played"
Le Roux was getting more and more paranoid about people in his organisation stealing from him. Without justification, he suspected that his self proclaimed 'Golden Boy' Jack was stealing from him - so he ordered a hit on Jack.
This was a huge mistake on Le Roux's part, as Jack then called a CIA hotline and went on the run. It was 18 months later that a DEA investigating Le Roux found Jack's message to the CIA. The DEA agent then called Jack. Scared for his life, Jack agreed to turn informant.
In the meantime, Le Roux then had a change of heart and apologised to Jack for ordering the hit on him. The DEA then asked Le Roux to go back to work for Le Roux - they now had someone on the inside.
To tempt Le Roux, the DEA devised a sting operation. They knew that Le Roux wanted novelty and excitement. So they fabricated the scenario that Jack had made contact with a high profile Colombian trafficker, and the Colombians wanted to bypass the Mexicans for their meth supply in the US.
Le Roux was hooked. However, the DEA needed to lure Le Roux out of Manila, as his network of corrupt officials would ensure he will never be arrested.
Jack needed to get Le Roux to Liberia (where the DEA had a trusted ally in Fombah Sirleaf, Head of Liberia's National Security Agency).
Jack achieved this by saying that they needed to meet a cartel representative to finalise the deal.
It worked, and Le Roux was arrested. Initially, Le Roux went into passive resistance - he was a big unit (hence the nickname "Fat Man") - and it took around 10 agents to get him on the plane to fly back to the US.
Well he settled on the plane, the first thing Le Roux said to the DEA agents was: "Well played gentlemen, well played."
He then said: "If you're looking at me, then clearly you're looking at bigger things..."
The DEA agents were intrigued: "No Paul, you're the prize - what could possibly be bigger than you?"
Le Roux responded: "Nation states gentlemen, nation states."
He then started to spew out extremely valuable information on North Korea and Iran.
Of course, this wasn't the only leverage Le Roux had...
The enforcers who were once on Le Roux's payroll needed to be held accountable for their numerous murders, and the DEA were desperate to get them behind bars. Le Roux was key in their eventual capture. But that's not all: a crucial piece to this story is Part 5...
Part 5/5 - TrueCrypt
As we discussed previously, Le Roux was rumoured to be a member of the TrueCrypt collective.
In November 2012, a man with the online handle Cincinnatus decided to throw a party in Hawaii. The idea arose out of an email exchange with Runa Sandvik, a developer and expert on the online software Tor, which allows its users to mask the physical location of their computers on the Internet.
After she gave a Tor tutorial on Reddit, Cincinnatus sent Sandvik an encrypted message. Cincinnatus told Sandvik that he lived in Hawaii. Sandvik mentioned that she would be there on vacation the following month and could give a talk on Tor.
Cincinnatus suggested they host a “cryptoparty,” a phenomenon that had arisen around that time among technology- and privacy-conscious activists. The date was set for December 11.
Unbeknownst to Sandvik, her fellow party planner was hatching a much more elaborate education scheme. Four days after he contacted Sandvik, Cincinnatus sent an email to the journalist Glenn Greenwald. “The security of people’s communications is very important to me,” he wrote. In a series of emails, he suggested that Greenwald set up an encrypted means by which sources could contact him.
Cincinnatus organized the cryptoparty at a hacker space called HiCapacity, located in the back of a furniture store in Honolulu.
When Sandvik arrived around 6 p.m., Cincinnatus introduced himself as Ed and told her that he worked at the computer-hardware company Dell.
Ed kicked off the evening by welcoming the attendees, then invited Sandvik to give her presentation on Tor. When she was finished, Ed pulled out his laptop, plugged it into the projector, and began his own instructional talk about TrueCrypt. In Ed’s presentation, Sandvik later wrote, he “pointed out that while the only known name associated with TrueCrypt is someone in the Czech Republic, TrueCrypt is one of the best open-source solutions available.”
Six months later, in June 2013, Greenwald and filmmaker Laura Poitras published the first of a series of articles that grew out of their contact with Cincinnatus.
In time they revealed that his full name was Edward Snowden, that he had worked in various capacities at the National Security Agency, and that he had downloaded and handed over a trove of documents from the NSA in an effort to blow the whistle on what he believed were egregious privacy encroachments by the U.S. government.
Among them was a document revealing that TrueCrypt was one of a small number of encryption programs that had withstood the NSA’s efforts to crack it.
What Snowden and the rest of the world wouldn’t know for another two years was that Paul Le Roux, the man whose code formed the foundation of True Crypt, was at that very moment in the custody of the U.S. government. Le Roux was in a bind, facing the full force of a U.S. federal prosecution for any number of his extraordinary array of crimes. The only way out was to spill his secrets...

The Political State and Future of Bitcoin

This post may not be so popular lol. But I'll tell you what you should hear.
One of the big pushbacks I have gotten on reddit is over the banking secrecy act. I have been repeatedly told that I am making shit up or being conspiratorial. This is very very foolish of this community. The statements and releases were in a document released by the FATF. I read it. It's right there. It's in the document. They've come right out and said exactly what they intend to do, and have told exchange CEO' "that's not our problem you WILL find a way to implement this".

I also follow the SEC and CFTC policy and press release strongly, and it is equally hostile and captured. It doesn't matter if a few people in the agencies are well intended. They don't call the shots. They are shadow regulatory industries controlled by people we will never see. The rich obviously. Dupont, Cargill, etc.

The bitcoin community has been deeply in denial about numerous issues pointed out. It has become a religion, incapable of receiving critique.
-Blind trust in Block stream
-Blind trust in Chinese miners and wallstreet institutional mining
-Blind trust in centralized exchanges
-Blind trust in the venture capital token M.O
-Blind trust in the idea of 'STO" security tokens sanctioned and graced by banks/regulators
-Blind trust in derivatives controlled by regulated bodies that can impose fractional reserve
-Blind trust in the meme of an ETF

If this community was far more educated in history and political economy and the US foreign policy, you would never trust these regulated wallstreet instruments, you would never trust a rubber stamp. I mean think about it, how many people in this community are hoping for Wallstreet and regulators to pump their bags. Because that has become the meme. They believe that the government approval and integration into the financial economy is going to pump their bags. How's that working out?
We have less commerce acceptance, less adoption, less users with a thousand dollars in their wallet, than a year ago.
The belief that bitcoin can exist in a vaacuum and bubble, that it can exist without decentralized infrastructure at the mercy of centralized infrastructure in a hostile environment and become mass adopted by nations of people is delusional. It hasn't worked in a decade. Bitcoin is a hobby horse for geeks, speculators, and a revenue stream for centralized wallstreet and financial institutions globally. It is a proxy of bitmain, of these other institutions, and is becoming more and more centralized. The gini coeeficient of bitcoin dwarfs fiat.

And the problem *is not bitcoin* the problem is the community believing in these memes and not learning from economic history in antiquity and not building the infrastructure outside the states control and forcing the state into diplomacy. Bitcoiners are failed anarchist, they don't know how to politically represent themselves, they aren't wobblies, they aren't like classic leftist who forced these concepts onto the gilded aged imperialist western republics, that forced them to not send kids to work in coalmines for 12 hours a day. We aren't politically commanding.

The banking secrecy act is a extinction level event for crypto. Will bitcoin survive? Of course? But it's going to set us back a decade. It's going to send us back to the stone age. And we are at a *profound* risk of the main chain breaking off and becoming the pseudo banking state corporate nexus geofenced kyced bitcoin with backdoored nodes and backdoored hardware wallets. The statist wont break bitcoin in half, we will. We will out of desperation after they sully it so severely that we have no choice but to hard fork it into a original version that can protect itself against the BSA. You say we won't but we will, when they cripple the global south's access to it, and they cripple the price, you will have your braveheart mercy moment, and the og cypherpunk will kick the bucket and pull the trigger. What has to be done will be done.

Centralized exchanges are completely incompatible with cypherpunk and anarchism and the white paper. We've tolerated CEX for a decade. Not only are governments a threat, but we will be continually crippled by Quadriga CX failures, Cryptopia, and Mount Gox failures. Because of toxic maximalism and toxic attitude towards building the fucking infrastructure to avoid this. The mainstream developers won't do it because they can't make any money. This will be a sacrificial act to build this system, just like Satoshi.

The current DEX system is like the 1960's darpa intranet. That is it. That's why it sucks. It's not the internet of DEX, it's not. And making the internet of DEX is really, really, really fucking hard bleeding edge computer science. If we want global adoption we need an internet, not an intranet. Having the liquidity of DEX divided into intranet is why we continue to rel on CEX. You want to get rid of the CEX, turn the fucking intranet into an internet, into an interchain. Stop relying on companies and ICO's and 1000 tokens for 1000 things, build the actual backbone. Support the developers. Pay your fucking developers. Stop calling everything a scam and everything vaporware. The internet isn't a fucking vaporware scam, so neither is the interchain. Maximalism is ludditism.

Crypto is for the global south, it's for emancipatory politics and independence, for the 99.99%, not the .01%. If you believe otherwise, and want you're "Citadel", Fuck You. Seriously. Read some political economy. Read Ellinor Ostrom, Bestiat, Spooner, Proudhon, etc. Crypto is suppoose to be a public good and a form of open source economy, not a recreation of tyranny, hierarchy, economic centralization, and worse yet just another banker shitcoin debt scam interest rate scam, which is what they are treating it and regulating and profiting off of it as.

Transcript of discussion between an ASIC designer and several proof-of-work designers from #monero-pow channel on Freenode this morning

[08:07:01] lukminer contains precompiled cn/r math sequences for some blocks: https://lukminer.org/2019/03/09/oh-kay-v4r-here-we-come/
[08:07:11] try that with RandomX :P
[08:09:00] tevador: are you ready for some RandomX feedback? it looks like the CNv4 is slowly stabilizing, hashrate comes down...
[08:09:07] how does it even make sense to precompile it?
[08:09:14] mine 1% faster for 2 minutes?
[08:09:35] naturally we think the entire asic-resistance strategy is doomed to fail :) but that's a high-level thing, who knows. people may think it's great.
[08:09:49] about RandomX: looks like the cache size was chosen to make it GPU-hard
[08:09:56] looking forward to more docs
[08:11:38] after initial skimming, I would think it's possible to make a 10x asic for RandomX. But at least for us, we will only make an ASIC if there is not a total ASIC hostility there in the first place. That's better for the secret miners then.
[08:13:12] What I propose is this: we are working on an Ethash ASIC right now, and once we have that working, we would invite tevador or whoever wants to come to HK/Shenzhen and we walk you guys through how we would make a RandomX ASIC. You can then process this input in any way you like. Something like that.
[08:13:49] unless asics (or other accelerators) re-emerge on XMR faster than expected, it looks like there is a little bit of time before RandomX rollout
[08:14:22] 10x in what measure? $/hash or watt/hash?
[08:14:46] watt/hash
[08:15:19] so you can make 10 times more efficient double precisio FPU?
[08:16:02] like I said let's try to be productive. You are having me here, let's work together!
[08:16:15] continue with RandomX, publish more docs. that's always helpful.
[08:16:37] I'm trying to understand how it's possible at all. Why AMD/Intel are so inefficient at running FP calculations?
[08:18:05] midipoet ([email protected]/web/irccloud.com/x-vszshqqxwybvtsjm) has joined #monero-pow
[08:18:17] hardware development works the other way round. We start with 1) math then 2) optimization priority 3) hw/sw boundary 4) IP selection 5) physical implementation
[08:22:32] This still doesn't explain at which point you get 10x
[08:23:07] Weren't you the ones claiming "We can accelerate ProgPoW by a factor of 3x to 8x." ? I find it hard to believe too.
[08:30:20] sure
[08:30:26] so my idea: first we finish our current chip
[08:30:35] from simulation to silicon :)
[08:30:40] we love this stuff... we do it anyway
[08:30:59] now we have a communication channel, and we don't call each other names immediately anymore: big progress!
[08:31:06] you know, we russians have a saying "it was smooth on paper, but they forgot about ravines"
[08:31:12] So I need a bit more details
[08:31:16] ha ha. good!
[08:31:31] that's why I want to avoid to just make claims
[08:31:34] let's work
[08:31:40] RandomX comes in Sep/Oct, right?
[08:31:45] Maybe
[08:32:20] We need to audit it first
[08:32:31] ok
[08:32:59] we don't make chips to prove sw devs that their assumptions about hardware are wrong. especially not if these guys then promptly hardfork and move to the next wrong assumption :)
[08:33:10] from the outside, this only means that hw & sw are devaluing each other
[08:33:24] neither of us should do this
[08:33:47] we are making chips that can hopefully accelerate more crypto ops in the future
[08:33:52] signing, verifying, proving, etc.
[08:34:02] PoW is just a feature like others
[08:34:18] sech1: is it easy for you to come to Hong Kong? (visa-wise)
[08:34:20] or difficult?
[08:34:33] or are you there sometimes?
[08:34:41] It's kind of far away
[08:35:13] we are looking forward to more RandomX docs. that's the first step.
[08:35:31] I want to avoid that we have some meme "Linzhi says they can accelerate XYZ by factor x" .... "ha ha ha"
[08:35:37] right? we don't want that :)
[08:35:39] doc is almost finished
[08:35:40] What docs do you need? It's described pretty good
[08:35:41] so I better say nothing now
[08:35:50] we focus on our Ethash chip
[08:36:05] then based on that, we are happy to walk interested people through the design and what else it can do
[08:36:22] that's a better approach from my view than making claims that are laughed away (rightfully so, because no silicon...)
[08:36:37] ethash ASIC is basically a glorified memory controller
[08:36:39] sech1: tevador said something more is coming (he just did it again)
[08:37:03] yes, some parts of RandomX are not described well
[08:37:10] like dataset access logic
[08:37:37] RandomX looks like progpow for CPU
[08:37:54] yes
[08:38:03] it is designed to reflect CPU
[08:38:34] so any ASIC for it = CPU in essence
[08:39:04] of course there are still some things in regular CPU that can be thrown away for RandomX
[08:40:20] uncore parts are not used, but those will use very little power
[08:40:37] except for memory controller
[08:41:09] I'm just surprised sometimes, ok? let me ask: have you designed or taped out an asic before? isn't it risky to make assumptions about things that are largely unknown?
[08:41:23] I would worry
[08:41:31] that I get something wrong...
[08:41:44] but I also worry like crazy that CNv4 will blow up, where you guys seem to be relaxed
[08:42:06] I didn't want to bring up anything RandomX because CNv4 is such a nailbiter... :)
[08:42:15] how do you guys know you don't have asics in a week or two?
[08:42:38] we don't have experience with ASIC design, but RandomX is simply designed to exactly fit CPU capabilities, which is the best you can do anyways
[08:43:09] similar as ProgPoW did with GPUs
[08:43:14] some people say they want to do asic-resistance only until the vast majority of coins has been issued
[08:43:21] that's at least reasonable
[08:43:43] yeah but progpow totally will not work as advertised :)
[08:44:08] yeah, I've seen that comment about progpow a few times already
[08:44:11] which is no surprise if you know it's just a random sales story to sell a few more GPUs
[08:44:13] RandomX is not permanent, we are expecting to switch to ASIC friendly in a few years if possible
[08:44:18] yes
[08:44:21] that makes sense
[08:44:40] linzhi-sonia: how so? will it break or will it be asic-able with decent performance gains?
[08:44:41] are you happy with CNv4 so far?
[08:45:10] ah, long story. progpow is a masterpiece of deception, let's not get into it here.
[08:45:21] if you know chip marketing it makes more sense
[08:45:24] linzhi-sonia: So far? lol! a bit early to tell, don't you think?
[08:45:35] the diff is coming down
[08:45:41] first few hours looked scary
[08:45:43] I remain skeptical: I only see ASICs being reasonable if they are already as ubiquitous as smartphones
[08:45:46] yes, so far so good
[08:46:01] we kbew the diff would not come down ubtil affter block 75
[08:46:10] yes
[08:46:22] but first few hours it looks like only 5% hashrate left
[08:46:27] looked
[08:46:29] now it's better
[08:46:51] the next worry is: when will "unexplainable" hashrate come back?
[08:47:00] you hope 2-3 months? more?
[08:47:05] so give it another couple of days. will probably overshoot to the downside, and then rise a bit as miners get updated and return
[08:47:22] 3 months minimum turnaround, yes
[08:47:28] nah
[08:47:36] don't underestimate asicmakers :)
[08:47:54] you guys don't get #1 priority on chip fabs
[08:47:56] 3 months = 90 days. do you know what is happening in those 90 days exactly? I'm pretty sure you don't. same thing as before.
[08:48:13] we don't do any secret chips btw
[08:48:21] 3 months assumes they had a complete design ready to go, and added the last minute change in 1 day
[08:48:24] do you know who is behind the hashrate that is now bricked?
[08:48:27] innosilicon?
[08:48:34] hyc: no no, and no. :)
[08:48:44] hyc: have you designed or taped out a chip before?
[08:48:51] yes, many years ago
[08:49:10] then you should know that 90 days is not a fixed number
[08:49:35] sure, but like I said, other makers have greater demand
[08:49:35] especially not if you can prepare, if you just have to modify something, or you have more programmability in the chip than some people assume
[08:50:07] we are chipmakers, we would never dare to do what you guys are doing with CNv4 :) but maybe that just means you are cooler!
[08:50:07] and yes, programmability makes some aspect of turnaround easier
[08:50:10] all fine
[08:50:10] I hope it works!
[08:50:28] do you know who is behind the hashrate that is now bricked?
[08:50:29] inno?
[08:50:41] we suspect so, but have no evidence
[08:50:44] maybe we can try to find them, but we cannot spend too much time on this
[08:50:53] it's probably not so much of a secret
[08:51:01] why should it be, right?
[08:51:10] devs want this cat-and-mouse game? devs get it...
[08:51:35] there was one leak saying it's innosilicon
[08:51:36] so you think 3 months, ok
[08:51:43] inno is cool
[08:51:46] good team
[08:51:49] IP design house
[08:51:54] in Wuhan
[08:52:06] they send their people to conferences with fake biz cards :)
[08:52:19] pretending to be other companies?
[08:52:26] sure
[08:52:28] ha ha
[08:52:39] so when we see them, we look at whatever card they carry and laugh :)
[08:52:52] they are perfectly suited for secret mining games
[08:52:59] they made at most $6 million in 2 months of mining, so I wonder if it was worth it
[08:53:10] yeah. no way to know
[08:53:15] but it's good that you calculate!
[08:53:24] this is all about cost/benefit
[08:53:25] then you also understand - imagine the value of XMR goes up 5x, 10x
[08:53:34] that whole "asic resistance" thing will come down like a house of cards
[08:53:41] I would imagine they sell immediately
[08:53:53] the investor may fully understand the risk
[08:53:57] the buyer
[08:54:13] it's not healthy, but that's another discussion
[08:54:23] so mid-June
[08:54:27] let's see
[08:54:49] I would be susprised if CNv4 ASICs show up at all
[08:54:56] surprised*
[08:54:56] why?
[08:55:05] is only an economic question
[08:55:12] yeah should be interesting. FPGAs will be near their limits as well
[08:55:16] unless XMR goes up a lot
[08:55:19] no, not *only*. it's also a technology question
[08:55:44] you believe CNv4 is "asic resistant"? which feature?
[08:55:53] it's not
[08:55:59] cnv4 = Rabdomx ?
[08:56:03] no
[08:56:07] cnv4=cryptinight/r
[08:56:11] ah
[08:56:18] CNv4 is the one we have now, I think
[08:56:21] since yesterday
[08:56:30] it's plenty enough resistant for current XMR price
[08:56:45] that may be, yes!
[08:56:55] I look at daily payouts. XMR = ca. 100k USD / day
[08:57:03] it can hold until October, but it's not asic resistant
[08:57:23] well, last 24h only 22,442 USD :)
[08:57:32] I think 80 h/s per watt ASICs are possible for CNv4
[08:57:38] linzhi-sonia where do you produce your chips? TSMC?
[08:57:44] I'm cruious how you would expect to build a randomX ASIC that outperforms ARM cores for efficiency, or Intel cores for raw speed
[08:57:48] curious
[08:58:01] yes, tsmc
[08:58:21] Our team did the world's first bitcoin asic, Avalon
[08:58:25] and upcoming 2nd gen Ryzens (64-core EPYC) will be a blast at RandomX
[08:58:28] designed and manufactured
[08:58:53] still being marketed?
[08:59:03] linzhi-sonia: do you understand what xmr wants to achieve, community-wise?
[08:59:14] Avalon? as part of Canaan Creative, yes I think so.
[08:59:25] there's not much interesting oing on in SHA256
[08:59:29] Inge-: I would think so, but please speak
[08:59:32] hyc: yes
[09:00:28] linzhi-sonia: i am curious to hear your thoughts. I am fairly new to this space myself...
[09:00:51] oh
[09:00:56] we are grandpas, and grandmas
[09:01:36] yet I have no problem understanding why ASICS are currently reviled.
[09:01:48] xmr's main differentiators to, let's say btc, are anonymity and fungibility
[09:01:58] I find the client terribly slow btw
[09:02:21] and I think the asic-forking since last may is wrong, doesn't create value and doesn't help with the project objectives
[09:02:25] which "the client" ?
[09:02:52] Monero GUI client maybe
[09:03:12] MacOS, yes
[09:03:28] What exactly is slow?
[09:03:30] linzhi-sonia: I run my own node, and use the CLI and Monerujo. Have not had issues.
[09:03:49] staying in sync
[09:03:49] linzhi-sonia: decentralization is also a key principle
[09:03:56] one that Bitcoin has failed to maintain
[09:04:39] hmm
[09:05:00] looks fairly decentralized to me. decentralization is the result of 3 goals imo: resilient, trustless, permissionless
[09:05:28] don't ask a hardware maker about physical decentralization. that's too ideological. we focus on logical decentralization.
[09:06:11] physical decentralization is important. with bulk of bitnoin mining centered on Chinese hydroelectric dams
[09:06:19] have you thought about including block data in the PoW?
[09:06:41] yes, of course.
[09:07:39] is that already in an algo?
[09:08:10] hyc: about "centered on chinese hydro" - what is your source? the best paper I know is this: https://coinshares.co.uk/wp-content/uploads/2018/11/Mining-Whitepaper-Final.pdf
[09:09:01] linzhi-sonia: do you mine on your ASICs before you sell them?
[09:09:13] besides testing of course
[09:09:45] that paper puts Chinese btc miners at 60% max
[09:10:05] tevador: I think everybody learned that that is not healthy long-term!
[09:10:16] because it gives the chipmaker a cost advantage over its own customers
[09:10:33] and cost advantage leads to centralization (physical and logical)
[09:10:51] you guys should know who finances progpow and why :)
[09:11:05] but let's not get into this, ha ha. want to keep the channel civilized. right OhGodAGirl ? :)
[09:11:34] tevador: so the answer is no! 100% and definitely no
[09:11:54] that "self-mining" disease was one of the problems we have now with asics, and their bad reputation (rightfully so)
[09:13:08] I plan to write a nice short 2-page paper or so on our chip design process. maybe it's interesting to some people here.
[09:13:15] basically the 5 steps I mentioned before, from math to physical
[09:13:32] linzhi-sonia: the paper you linked puts 48% of bitcoin mining in Sichuan. the total in China is much more than 60%
[09:13:38] need to run it by a few people to fix bugs, will post it here when published
[09:14:06] hyc: ok! I am just sharing the "best" document I know today. it definitely may be wrong and there may be a better one now.
[09:14:18] hyc: if you see some reports, please share
[09:14:51] hey I am really curious about this: where is a PoW algo that puts block data into the PoW?
[09:15:02] the previous paper I read is from here http://hackingdistributed.com/2018/01/15/decentralization-bitcoin-ethereum/
[09:15:38] hyc: you said that already exists? (block data in PoW)
[09:15:45] it would make verification harder
[09:15:49] linzhi-sonia: https://the-eye.eu/public/Books/campdivision.com/PDF/Computers%20General/Privacy/bitcoin/meh/hashimoto.pdf
[09:15:51] but for chips it would be interesting
[09:15:52] we discussed the possibility about a year ago https://www.reddit.com/Monero/comments/8bshrx/what_we_need_to_know_about_proof_of_work_pow/
[09:16:05] oh good links! thanks! need to read...
[09:16:06] I think that paper by dryja was original
[09:17:53] since we have a nice flow - second question I'm very curious about: has anyone thought about in-protocol rewards for other functions?
[09:18:55] we've discussed micropayments for wallets to use remote nodes
[09:18:55] you know there is a lot of work in other coins about STARK provers, zero-knowledge, etc. many of those things very compute intense, or need to be outsourced to a service (zether). For chipmakers, in-protocol rewards create an economic incentive to accelerate those things.
[09:19:50] whenever there is an in-protocol reward, you may get the power of ASICs doing something you actually want to happen
[09:19:52] it would be nice if there was some economic reward for running a fullnode, but no one has come up with much more than that afaik
[09:19:54] instead of fighting them off
[09:20:29] you need to use asics, not fight them. that's an obvious thing to say for an asicmaker...
[09:20:41] in-protocol rewards can be very powerful
[09:20:50] like I said before - unless the ASICs are so useful they're embedded in every smartphone, I dont see them being a positive for decentralization
[09:21:17] if they're a separate product, the average consumer is not going to buy them
[09:21:20] now I was talking about speedup of verifying, signing, proving, etc.
[09:21:23] they won't even know what they are
[09:22:07] if anybody wants to talk about or design in-protocol rewards, please come talk to us
[09:22:08] the average consumer also doesn't use general purpose hardware to secure blockchains either
[09:22:14] not just for PoW, in fact *NOT* for PoW
[09:22:32] it requires sw/hw co-design
[09:23:10] we are in long-term discussions/collaboration over this with Ethereum, Bitcoin Cash. just talk right now.
[09:23:16] this was recently published though suggesting more uptake though I guess https://btcmanager.com/college-students-are-the-second-biggest-miners-of-cryptocurrency/
[09:23:29] I find it pretty hard to believe their numbers
[09:24:03] well
[09:24:09] sorry, original article: https://www.pcmag.com/news/366952/college-kids-are-using-campus-electricity-to-mine-crypto
[09:24:11] just talk, no? rumors
[09:24:18] college students are already more educated than the average consumer
[09:24:29] we are not seeing many such customers anymore
[09:24:30] it's data from cisco monitoring network traffic
[09:24:33] and they're always looking for free money
[09:24:48] of course anyone with "free" electricity is inclined to do it
[09:24:57] but look at the rates, cannot make much money
[09:26:06] Ethereum is a bloated collection of bugs wrapped in a UI. I suppose they need all the help they can get
[09:26:29] Bitcoin Cash ... just another get rich quick scheme
[09:26:38] hmm :)
[09:26:51] I'll give it back to you, ok? ha ha. arrogance comes before the fall...
[09:27:17] maye we should have a little fun with CNv4 mining :)
[09:27:25] ;)
[09:27:38] come on. anyone who has watched their track record... $75M lost in ETH at DAO hack
[09:27:50] every smart contract that comes along is just waiting for another hack
[09:27:58] I just wanted to throw out the "in-protocol reward" thing, maybe someone sees the idea and wants to cowork. maybe not. maybe it's a stupid idea.
[09:29:18] linzhi-sonia: any thoughts on CN-GPU?
[09:29:55] CN-GPU has one positive aspect - it wastes chip area to implement all 18 hash algorithms
[09:30:19] you will always hear roughly the same feedback from me:
[09:30:52] "This algorithm very different, it heavy use floating point operations to hurt FPGAs and general purpose CPUs"
[09:30:56] the problem is, if it's profitable for people to buy ASIC miners and mine, it's always more profitable for the manufacturer to not sell and mine themselves
[09:31:02] "hurt"
[09:31:07] what is the point of this?
[09:31:15] it totally doesn't work
[09:31:24] you are hurting noone, just demonstrating lack of ability to think
[09:31:41] what is better: algo designed for chip, or chip designed for algo?
[09:31:43] fireice does it on daily basis, CN-GPU is a joke
[09:31:53] tevador: that's not really true, especially in a market with such large price fluctuations as cryptocurrency
[09:32:12] it's far less risky to sell miners than mine with them and pray that price doesn't crash for next six months
[09:32:14] I think it's great that crypto has a nice group of asicmakers now, hw & sw will cowork well
[09:32:36] jwinterm yes, that's why they premine them and sell after
[09:32:41] PoW is about being thermodynamically and cryptographically provable
[09:32:45] premining with them is taking on that risk
[09:32:49] not "fork when we think there are asics"
[09:32:51] business is about risk minimization
[09:32:54] that's just fear-driven
[09:33:05] Inge-: that's roughly the feedback
[09:33:24] I'm not saying it hasn't happened, but I think it's not so simple as saying "it always happens"
[09:34:00] jwinterm: it has certainly happened on BTC. and also on XMR.
[09:34:19] ironically, please think about it: these kinds of algos indeed prove the limits of the chips they were designed for. but they don't prove that you cannot implement the same algo differently! cannot!
[09:34:26] Risk minimization is not starting a business at all.
[09:34:34] proof-of-gpu-limit. proof-of-cpu-limit.
[09:34:37] imagine you have a money printing machine, would you sell it?
[09:34:39] proves nothing for an ASIC :)
[09:35:05] linzhi-sonia: thanks. I dont think anyone believes you can't make a more efficient cn-gpu asic than a gpu - but that it would not be orders of magnitude faster...
[09:35:24] ok
[09:35:44] like I say. these algos are, that's really ironic, designed to prove the limitatios of a particular chip in mind of the designer
[09:35:50] exactly the wrong way round :)
[09:36:16] like the cache size in RandomX :)
[09:36:18] beautiful
[09:36:29] someone looked at GPU designs
[09:37:31] linzhi-sonia can you elaborate? Cache size in RandomX was selected to fit CPU cache
[09:37:52] yes
[09:38:03] too large for GPU
[09:38:11] as I said, we are designing the algorithm to exactly fit CPU capabilities, I do not claim an ASIC cannot be more efficient
[09:38:16] ok!
[09:38:29] when will you do the audit?
[09:38:35] will the results be published in a document or so?
[09:38:37] I claim that single-chip ASIC is not viable, though
[09:39:06] you guys are brave, noone disputes that. 3 anti-asic hardforks now!
[09:39:18] 4th one coming
[09:39:31] 3 forks were done not only for this
[09:39:38] they had scheduled updates in the first place
[09:48:10] Monero is the #1 anti-asic fighter
[09:48:25] Monero is #1 for a lot of reasons ;)
[09:48:40] It's the coin with the most hycs.
[09:48:55] mooooo
[09:59:06] sneaky integer overflow, bug squished
[10:38:00] p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has joined #monero-pow
[11:10:53] The convo here is wild
[11:12:29] it's like geo-politics at the intersection of software and hardware manufacturing for thermoeconomic value.
[11:13:05] ..and on a Sunday.
[11:15:43] midipoet: hw and sw should work together and stop silly games to devalue each other. to outsiders this is totally not attractive.
[11:16:07] I appreciate the positive energy here to try to listen, learn, understand.
[11:16:10] that's a start
[11:16:48] <-- p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has quit (Quit: Leaving)
[11:16:54] we won't do silly mining against xmr "community" wishes, but not because we couldn'd do it, but because it's the wrong direction in the long run, for both sides
[11:18:57] linzhi-sonia: I agree to some extent. Though, in reality, there will always be divergence between social worlds. Not every body has the same vision of the future. Reaching societal consensus on reality tomorrow is not always easy
[11:20:25] absolutely. especially at a time when there is so much profit to be made from divisiveness.
[11:20:37] someone will want to make that profit, for sure
[11:24:32] Yes. Money distorts.
[11:24:47] Or wealth...one of the two
[11:26:35] Too much physical money will distort rays of light passing close to it indeed.

Which type of curren(t) do you want to see(cy)? A analysis of the intention behind bitcoin(s). [Part I]

Bitcoin was released to the world in 2009 by someone (or a group) who authored a technical whitepaper, released the source code to the protocol and commented on a few p2p forums and mailing lists under the pseudonym Satoshi Nakamoto for a few months prior and a few years afterwards before leaving the project. The project was left in the hands of Gavin Andresson who was another cryptographer that satoshi communicated regularly with on the forums and had been one of the first people involved in the project. Some time after satoshi left, one of his accounts was allegedly hacked and bitcointalk (the primary forum) itself was hacked so a meme kind of emerged that satoshi wouldn't be able to post again from his accounts or that posting from them would be dubious. In 2016 an Australian by the name of Craig S Wright was exposed by Wired and Gizmodo as potentially being the inventor of bitcoin. Craig then signed privately for Gavin Andreson, Jon Matonis but then when he was supposed to cryptographically sign to a journalist the method performed did not hold up to public scrutiny because he could have copy pasted a fragment from an earlier known signed message from satoshi and not generated it himself with the private keys. This cast a lot of doubt from many on the man's claims and he published an article saying he wasn't brave enough to sign.
Since then the term cryptocurrency has blown out massively to include anything with a distributed ledger technology, a token, a security, and has really just devolved into a cesspit of buzzwords and disinformation. Once satoshi disappeared in 2011 and left the repo in the hands of Gavin and the open source community, it left a power vacuum in the space for how to interpret the protocol, whitepaper and handle the development. Gavin Andresson brought some other developers on board from the forums and mailing lists, Shortly after Gavin gave some other developers commit access, bitcointalk was hacked and these new developers somehow deleted gavin from the github repo due to apparent concern that his account was compromised from the hack and afterwards once he validated his identity in certain accounts he was never given access again. Gavin stopped being involved with the project after that.
In the time following satoshi's departure a meme had evolved that satoshi had left because Gavin had met with the CIA to discuss bitcoin. This meme combined with the interpretation of what satoshi meant when he included the quote "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" in the genesis block, the subsequent rise and fall of silk road and darknet markets, and the general lore of the space, his cypherpunk mailing list associations had led the scene to paint/project upon him as some kind of government hating tax dodging l33t h4xor demigod.
Although in the title of the whitepaper it was described as p2p cash, bitcoin as most know it is now is marketed as a store of value. Although it was defined as the longest Proof of Work chain of digital signatures, bitcoin as most know it in actual fact has segregated witnesses (signatures) in the protocol. Although satoshi attests to how bitcoin is designed to scale to giant block sizes hosted and mined in data centers that never really hits a scaling ceiling, it is being sold as that even at 1MB size, the damage has already been done and the blocksize should be 300kB because every user needs to be able to run a full node for bitcoin to validate their own transactions with the lowest hardware and bandwidth requirements possible. A high vertice count with everyone running a (non-mining) full node is said to protect the network against malicious actions by the big bad government while graph theory states that it is the degree of inter connectivity of the vertcies (edge number) that confers security of the network against sybil attacks as it brings the number of hops down.
This decoupling from the original vision has led to development and scaling of bitcoin stalling for many years which led to the proliferation of many alt coins rising up to claim they possess superior attributes to bitcoin or can work in conjunction with bitcoin in a gold and silver type relationship, or serve a different use case to bitcoin. The debate between the groups that represented the opposing roadmaps reached a climax with bitcoin itself forking into two now separate blockchains with the minority chain being declared the imposter by social media claiming hashpower and the market had chosen despite their chain changing on the protocol level to implement segregated witnesses and reject the block size increase. These two now separate chains both forked again to birth bitcoin gold and diamond on the segwit chain and bitcoin cash and bitcoin sv on the non segwit chain. At the non segwit chain fork, bitcoin cash implemented checkpointing at the protocol level whereas bitcoin sv maintained the original nakamoto consensus and sought to scale greater than the 32MB blocksize limit BCH maintained with 64MB blocks.
Following these forking events both BTC (segwit) and BCH (checkpoints) also implemented Schnorr signatures which was marketed as economising the size of a typical bitcoin transaction though in actual fact it can be used to obfuscate signatures and allow for the mixing of coins to mask the chain of digital signatures and essentially "anonymously" launder money. The BSV chain (now Stewarded by Dr Craig Wright) was then declared the loser of that hash war by people heralding the power of the market and the miners to democratize money. The problem with such a claim though is just like current polical democracy, this apparent democratisation of money was just as susceptible to the influence of those who control the cryptocurrency media and just like in politics, there is a cabal like group that exerts a disproportionate influence over the narrative and appears to serve the interests of those in on the racket rather than those it is allegedly informing.
The main forums for discussion of cryptocurrency originally were bitcoin.org, bitcointalk.org and /Bitcoin with all three of them for some time sharing the same moderator theymos. Coindesk and the bitcoinmagazine (started by ethereum devs) were some early sources, talking heads like andreas antonopolos (andreasma), peter todd (petertodd) and greg maxwell (nullc) being propped up as sources of knowledge on what is the best course of action for scaling and endorsing solutions like small blocks, second layer solutions and segwit as a necessarry bitcoin improvement protocol (BIP) while people like Roger Ver (memory dealers) and Dr Craig Wright (craig_s_wright) endorsing a block size increase. Because the core developers had chosen to scale with small blocks and lots of nodes on the network were signalling in support of Segwit any discussion of a big block alternative was considered discussion of an alt coin and deleted and eventually users banned from /bitcoin. Out of that incident /btc emerged as an apparently censorship free forum for the discussion of all scaling plans for bitcoin but was ultimately a partisan sub populated with dejected big blockers. After the BCH fork, discussion for bitcoin sv exists on a few subs /bsv (modded by BCHers), /bitcoinsv (moderated by the lead technician at nChain (Craig Wright's company) and /bitcoincashsv where many users have been banned from both /bitcoin and /btc.
Now this so far is just kind of a synposis of the history of bitcoin covering all three of the main contenders for the legitimate claimant of the name but the part 2 will look more at what kind of drastically different societies would be built upon the different versions of the protocol and what may seem like their subtle differences and which one is likely to succeed.

Understanding Fundamental Effects on Price

Another really huge issue with the btc community in general, and this reddit especially, is the lack of nuance on price. And again, an unwillingness to accept critique.
There are several scenario that can play out with price, but in some of those scenario, we may even see a huge price pump, while *still failing at adoption*. And I think that's an important distinction to make. Just because wallstreet pumps the price for reasons that only concern the rich and institutions, does not equate to adoption. It does not equate to us making vital changes for the betterment of the network and adoption. It just doesn't.

Wallstreet is perfectly content with hyper regulated bitcoin that is totally irrelevant for the common man and unadopted and unused, they are perfectly fine treating bitcoin as a glorified sovereign bond and international form of settlement. That is how the institutions and rich see it. They see it much like they see bonds and gold, and are willing to treat it as such. This is even a positive in some regard because it brings monetary transparency into the banking and wealth sector.

But it does not address cypherpunk, emancipatory politics, or global poverty, or individual sovereignty. And it is acheived largely through extreme centralization and hyper invasive surveillance. Be clear, they can pump the price to 250,000 while still controlling everything through Patriot Act, AMLD5, NDAA, and FACTA and the banking secrecy Act. All of which Bitcoin is entirely ideologically incompatible with. But that's just fine, because the rich already comply with those laws (mostly). They already price in the regulatory and compliance costs of an institution, of an offshore tax haven.

That's just it. IT's fine for them to do this to btc, because the laws are designed for them. They create the barriers only they can afford to play in, while hurting it for everyone else.

The average common man in the world, and any developing country should be able to easily acquire btc without kyc. Period. It shouldn't be a surveillance state. I recently listened to Peter McCormack interview a darkmarket guy and I completely agree. We need to engineer away from on ramps, we need to engineer away from payment gates that involve fiat, and we need to all use coinjoiners and mixing technology. It needs to be the standard. There are so many reasons to use coinjoining for non illegality. Privacy is a fundamental need.

And internet 4.0 for finance is contingent on a lot of technology. These aren't really coins either. It is backbone technology to better facilitate bitcoin. But we have to have layer two solutions. It doesn't matter whether it's RSK or plasma, or both, we just need the secondary layer to pay for distributed processing, server function, matching, liquidity, file storage, atomic swaps, network gas, etc. DeFi network value cannot be conflated with the supply and demand of btc itself, we don't need permissioned side chains, we need permissionless open source side chains and interoperatibilty platforms that will protect the privacy of bitcoin and facilitate it on decentralized exchanges. On exchanges that cannot be taken down. To do that we need staggering amounts of technology innovation and thoroughput, that will require people to host nodes, mine and stake these ancillary services to protect the backbone of bitcoin commerce.

Anyone who is into toxic maximalism. Let it be known that you are willfully promoting corporate bitcoin supported by massive centralized players who will treat it as a bond or settlement statist instrument. You're promoting the support of bitcoin on an entirely captured regulatory framework and an entirely captured unsafe unsecure regular internet controlled by the clearnet and amazon and google and heavily surveiled. .Org just privatize for fuck sakes. And any DNS can be compromised, any .com site can be siezed. This normal backbone is entirely inappropriate for bitcoin. Centralized exchanges and payment apps like cash app are entirely inappropriate for bitcoin.

You should be able to visit a IFPS site, connect a hardware wallet to any DEX or DAPP and immediately trade with the same speed and liquidity of binance and bitmex. The user interface should be simple and approachable to the layman. We need a liquidity interbank controlled by SPV server and dark node. Payment incentives for people to host liquidity to the network on plasma, radon, cosmos, uniswap, eventually all the DEX will simply be connected by interchain liquidity.

Crypto has to be extremely unfettered. The regulators and wallstreet have strangled it and will continue to do so. Some people have forgotten that this is a battle for financial sovereignty and protection against wealth confiscation. Only when they realize that they can't control us, will they be forced to sit down at the legislative table and negotiate with common people. You have to bring your government to heel.

r/Bitcoin recap - February 2019

A Beginners Guide to Bitcoin, Blockchain & Cryptocurrency

As cryptocurrency, and blockchain technology become more abundant throughout our society, it’s important to understand the inner workings of this technology, especially if you plan to use cryptocurrency as an investment vehicle. If you’re new to the crypto-sphere, learning about Bitcoin makes it much easier to understand other cryptocurrencies as many other altcoins' technologies are borrowed directly from Bitcoin.
Bitcoin is one of those things that you look into only to discover you have more questions than answers, and right as you’re starting to wrap your head around the technology; you discover the fact that Bitcoin has six other variants (forks), the amount of politics at hand, or that there are over a thousand different cryptocurrencies just as complex if not even more complex than Bitcoin.
We are currently in the infancy of blockchain technology and the effects of this technology will be as profound as the internet. This isn’t something that’s just going to fade away into history as you may have been led to believe. I believe this is something that will become an integral part of our society, eventually embedded within our technology. If you’re a crypto-newbie, be glad that you're relatively early to the industry. I hope this post will put you on the fast-track to understanding Bitcoin, blockchain, and how a large percentage of cryptocurrencies work.

Community Terminology

Altcoin: Short for alternative coin. There are over 1,000 different cryptocurrencies. You’re probably most familiar with Bitcoin. Anything that isn’t Bitcoin is generally referred to as an altcoin.
HODL: Misspelling of hold. Dank meme accidentally started by this dude. Hodlers are much more interested in long term gains rather than playing the risky game of trying to time the market.
TO THE MOON: When a cryptocurrency’s price rapidly increases. A major price spike of over 1,000% can look like it’s blasting off to the moon. Just be sure you’re wearing your seatbelt when it comes crashing down.
FUD: Fear. Uncertainty. Doubt.
FOMO: Fear of missing out.
Bull Run: Financial term used to describe a rising market.
Bear Run: Financial term used to describe a falling market.

What Is Bitcoin?

Bitcoin (BTC) is a decentralized digital currency that uses cryptography to secure and ensure validity of transactions within the network. Hence the term crypto-currency. Decentralization is a key aspect of Bitcoin. There is no CEO of Bitcoin or central authoritative government in control of the currency. The currency is ran and operated by the people, for the people. One of the main development teams behind Bitcoin is blockstream.
Bitcoin is a product of blockchain technology. Blockchain is what allows for the security and decentralization of Bitcoin. To understand Bitcoin and other cryptocurrencies, you must understand to some degree, blockchain. This can get extremely technical the further down the rabbit hole you go, and because this is technically a beginners guide, I’m going to try and simplify to the best of my ability and provide resources for further technical reading.

A Brief History

Bitcoin was created by Satoshi Nakamoto. The identity of Nakamoto is unknown. The idea of Bitcoin was first introduced in 2008 when Nakamoto released the Bitcoin white paper - Bitcoin: A Peer-to-Peer Electronic Cash System. Later, in January 2009, Nakamoto announced the Bitcoin software and the Bitcoin network officially began.
I should also mention that the smallest unit of a Bitcoin is called a Satoshi. 1 BTC = 100,000,000 Satoshis. When purchasing Bitcoin, you don’t actually need to purchase an entire coin. Bitcoin is divisible, so you can purchase any amount greater than 1 Satoshi (0.00000001 BTC).

What Is Blockchain?

Blockchain is a distributed ledger, a distributed collection of accounts. What is being accounted for depends on the use-case of the blockchain itself. In the case of Bitcoin, what is being accounted for is financial transactions.
The first block in a blockchain is referred to as the genesis block. A block is an aggregate of data. Blocks are also discovered through a process known as mining (more on this later). Each block is cryptographically signed by the previous block in the chain and visualizing this would look something akin to a chain of blocks, hence the term, blockchain.
For more information regarding blockchain I’ve provided more resouces below:

What is Bitcoin Mining

Bitcoin mining is one solution to the double spend problem. Bitcoin mining is how transactions are placed into blocks and added onto the blockchain. This is done to ensure proof of work, where computational power is staked in order to solve what is essentially a puzzle. If you solve the puzzle correctly, you are rewarded Bitcoin in the form of transaction fees, and the predetermined block reward. The Bitcoin given during a block reward is also the only way new Bitcoin can be introduced into the economy. With a halving event occurring roughly every 4 years, it is estimated that the last Bitcoin block will be mined in the year 2,140. (See What is Block Reward below for more info).
Mining is one of those aspects of Bitcoin that can get extremely technical and more complicated the further down the rabbit hole you go. An entire website could be created (and many have) dedicated solely to information regarding Bitcoin mining. The small paragraph above is meant to briefly expose you to the function of mining and the role it plays within the ecosystem. It doesn’t even scratch the surface regarding the topic.

How do you Purchase Bitcoin?

The most popular way to purchase Bitcoin through is through an online exchange where you trade fiat (your national currency) for Bitcoin.
Popular exchanges include:
  • Coinbase
  • Kraken
  • Cex
  • Gemini
There’s tons of different exchanges. Just make sure you find one that supports your national currency.

Volatility

Bitcoin and cryptocurrencies are EXTREMELY volatile. Swings of 30% or more within a few days is not unheard of. Understand that there is always inherent risks with any investment. Cryptocurrencies especially. Only invest what you’re willing to lose.

Transaction & Network Fees

Transacting on the Bitcoin network is not free. Every purchase or transfer of Bitcoin will cost X amount of BTC depending on how congested the network is. These fees are given to miners as apart of the block reward.
Late 2017 when Bitcoin got up to $20,000USD, the average network fee was ~$50. Currently, at the time of writing this, the average network fee is $1.46. This data is available in real-time on BitInfoCharts.

Security

In this new era of money, there is no central bank or government you can go to in need of assistance. This means the responsibility of your money falls 100% into your hands. That being said, the security regarding your cryptocurrency should be impeccable. The anonymity provided by cryptocurrencies alone makes you a valuable target to hackers and scammers. Below I’ve detailed out best practices regarding securing your cryptocurrency.

Two-Factor Authentication (2FA)

Two-factor authentication is a second way of authenticating your identity upon signing in to an account. Most cryptocurrency related software/websites will offer or require some form of 2FA. Upon creation of any crypto-related account find the Security section and enable 2FA.

SMS Authentication

The most basic form of 2FA which you are probably most familiar with. This form of authentication sends a text message to your smartphone with a special code that will allow access to your account upon entry. Note that this is not the safest form of 2FA as you may still be vulnerable to what is known as a SIM swap attack. SIM swapping is a social engineering method in which an attacker will call up your phone carrier, impersonating you, in attempt to re-activate your SIM card on his/her device. Once the attacker has access to your SIM card he/she now has access to your text messages which can then be used to access your online accounts. You can prevent this by using an authenticator such as Google Authenticator.

Authenticator

The use of an authenticator is the safest form of 2FA. An authenticator is installed on a seperate device and enabling it requires you input an ever changing six digit code in order to access your account. I recommend using Google Authenticator.
If a website has the option to enable an authenticator, it will give you a QR code and secret key. Use Google Authenticator to scan the QR code. The secret key consists of a random string of numbers and letters. Write this down on a seperate sheet of paper and do not store it on a digital device.
Once Google Authenticator has been enabled, every time you sign into your account, you will have to input a six-digit code that looks similar to this. If you happen to lose or damage the device you have Google Authenticator installed on, you will be locked out of your account UNLESS you have access to the secret key (which you should have written down).

Hardware Wallets

A wallet is what you store Bitcoin and cryptocurrency on. I’ll provide resources on the different type of wallets later but I want to emphasize the use of a hardware wallet (aka cold storage).
Hardware wallets are the safest way of storing cryptocurrency because it allows for your crypto to be kept offline in a physical device. After purchasing crypto via an exchange, I recommend transferring it to cold storage. The most popular hardware wallets include the Ledger Nano S, and Trezor.
Hardware wallets come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key as well as any other sensitive information in a safety deposit box.
I know this all may seem a bit manic, but it is important you take the necessary security precautions in order to ensure the safety & longevity of your cryptocurrency.

Technical Aspects of Bitcoin

TL;DR
  • Address: What you send Bitcoin to.
  • Wallet: Where you store your Bitcoin
  • Max Supply: 21 million
  • Block Time: ~10 minutes
  • Block Size: 1-2 MB
  • Block Reward: BTC reward received from mining.

What is a Bitcoin Address?

A Bitcoin address is what you send Bitcoin to. If you want to receive Bitcoin you’d give someone your Bitcoin address. Think of a Bitcoin address as an email address for money.

What is a Bitcoin Wallet?

As the title implies, a Bitcoin wallet is anything that can store Bitcoin. There are many different types of wallets including paper wallets, software wallets and hardware wallets. It is generally advised NOT to keep cryptocurrency on an exchange, as exchanges are prone to hacks (see Mt. Gox hack).
My preferred method of storing cryptocurrency is using a hardware wallet such as the Ledger Nano S or Trezor. These allow you to keep your crypto offline in physical form and as a result, much more safe from hacks. Paper wallets also allow for this but have less functionality in my opinion.
After I make crypto purchases, I transfer it to my Ledger Nano S and keep that in a safe at home. Hardware wallets also come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key in a safety deposit box.

What is Bitcoins Max Supply?

The max supply of Bitcoin is 21 million. The only way new Bitcoins can be introduced into the economy are through block rewards which are given after successfully mining a block (more on this later).

What is Bitcoins Block Time?

The average time in which blocks are created is called block time. For Bitcoin, the block time is ~10 minutes, meaning, 10 minutes is the minimum amount of time it will take for a Bitcoin transaction to be processed. Note that transactions on the Bitcoin network can take much longer depending on how congested the network is. Having to wait a few hours or even a few days in some instances for a transaction to clear is not unheard of.
Other cryptocurrencies will have different block times. For example, Ethereum has a block time of ~15 seconds.
For more information on how block time works, Prabath Siriwardena has a good block post on this subject which can be found here.

What is Bitcoins Block Size?

There is a limit to how large blocks can be. In the early days of Bitcoin, the block size was 36MB, but in 2010 this was reduced to 1 MB in order to prevent distributed denial of service attacks (DDoS), spam, and other malicious use on the blockchain. Nowadays, blocks are routinely in excess of 1MB, with the largest to date being somewhere around 2.1 MB.
There is much debate amongst the community on whether or not to increase Bitcoin’s block size limit to account for ever-increasing network demand. A larger block size would allow for more transactions to be processed. The con argument to this is that decentralization would be at risk as mining would become more centralized. As a result of this debate, on August 1, 2017, Bitcoin underwent a hard-fork and Bitcoin Cash was created which has a block size limit of 8 MB. Note that these are two completely different blockchains and sending Bitcoin to a Bitcoin Cash wallet (or vice versa) will result in a failed transaction.
Update: As of May 15th, 2018 Bitcoin Cash underwent another hard fork and the block size has increased to 32 MB.
On the topic of Bitcoin vs Bitcoin Cash and which cryptocurrency is better, I’ll let you do your own research and make that decision for yourself. It is good to know that this is a debated topic within the community and example of the politics that manifest within the space. Now if you see community members arguing about this topic, you’ll at least have a bit of background to the issue.

What is Block Reward?

Block reward is the BTC you receive after discovering a block. Blocks are discovered through a process called mining. The only way new BTC can be added to the economy is through block rewards and the block reward is halved every 210,000 blocks (approximately every 4 years). Halving events are done to limit the supply of Bitcoin. At the inception of Bitcoin, the block reward was 50BTC. At the time of writing this, the block reward is 12.5BTC. Halving events will continue to occur until the amount of new Bitcoin introduced into the economy becomes less than 1 Satoshi. This is expected to happen around the year 2,140. All 21 million Bitcoins will have been mined. Once all Bitcoins have been mined, the block reward will only consist of transaction fees.

Technical Aspects Continued

Understanding Nodes

Straight from the Bitcoin.it wiki
Any computer that connects to the Bitcoin network is called a node. Nodes that fully verify all of the rules of Bitcoin are called full nodes.
In other words, full nodes are what verify the Bitcoin blockchain and they play a crucial role in maintaining the decentralized network. Full nodes store the entirety of the blockchain and validate transactions. Anyone can participate in the Bitcoin network and run a full node. Bitcoin.org has information on how to set up a full node. Running a full node also gives you wallet capabilities and the ability to query the blockchain.
For more information on Bitcoin nodes, see Andreas Antonopoulos’s Q&A on the role of nodes.

What is a Fork?

A fork is a divergence in a blockchain. Since Bitcoin is a peer-to-peer network, there’s an overall set of rules (protocol) in which participants within the network must abide by. These rules are put in place to form network consensus. Forks occur when implementations must be made to the blockchain or if there is disagreement amongst the network on how consensus should be achieved.

Soft Fork vs Hard Fork

The difference between soft and hard forks lies in compatibility. Soft forks are backwards compatible, hard forks are not. Think of soft forks as software upgrades to the blockchain, whereas hard forks are a software upgrade that warrant a completely new blockchain.
During a soft fork, miners and nodes upgrade their software to support new consensus rules. Nodes that do not upgrade will still accept the new blockchain.
Examples of Bitcoin soft forks include:
A hard fork can be thought of as the creation of a new blockchain that X percentage of the community decides to migrate too. During a hard fork, miners and nodes upgrade their software to support new consensus rules, Nodes that do not upgrade are invalid and cannot accept the new blockchain.
Examples of Bitcoin hard forks include:
  • Bitcoin Cash
  • Bitcoin Gold
Note that these are completely different blockchains and independent from the Bitcoin blockchain. If you try to send Bitcoin to one of these blockchains, the transaction will fail.

A Case For Bitcoin in a World of Centralization

Our current financial system is centralized, which means the ledger(s) that operate within this centralized system are subjugated to control, manipulation, fraud, and many other negative aspects that come with this system. There are also pros that come with a centralized system, such as the ability to swiftly make decisions. However, at some point, the cons outweigh the pros, and change is needed. What makes Bitcoin so special as opposed to our current financial system is that Bitcoin allows for the decentralized transfer of money. Not one person owns the Bitcoin network, everybody does. Not one person controls Bitcoin, everybody does. A decentralized system in theory removes much of the baggage that comes with a centralized system. Not to say the Bitcoin network doesn’t have its problems (wink wink it does), and there’s much debate amongst the community as to how to go about solving these issues. But even tiny steps are significant steps in the world of blockchain, and I believe Bitcoin will ultimately help to democratize our financial system, whether or not you believe it is here to stay for good.

Final Conclusions

Well that was a lot of words… Anyways I hope this guide was beneficial, especially to you crypto newbies out there. You may have come into this realm not expecting there to be an abundance of information to learn about. I know I didn’t. Bitcoin is only the tip of the iceberg, but now that you have a fundamental understanding of Bitcoin, learning about other cryptocurrencies such as Litecoin, and Ethereum will come more naturally.
Feel free to ask questions below! I’m sure either the community or myself would be happy to answer your questions.
Thanks for reading!
