Should (or will?) Bitcoin mining swing away from the industrial-scale miners towards the individual/DIY miner culture we had at the beginning? Or is this all going according to Satoshi's plan? And is the industrial-scale Bitcoin miner ecosystem good for decentralization, or endangering it?

Research as if it was the 21st century

Reading all the news about the coronavirus, and the research attempts in either antivirals, or vaccines, I realized something is afoot about the progress.
Why are we not seeing a full-scale, open, transparent collaboration among both commercial, and academic research labs - with no industrial secrecy? Where are the major AI networks getting fed with the data, both commercial ones (looking at you Alibaba, Google, IBM Watson, Yandex, etc), and academic ones (MIT, Berkley, etc)? What if industrial-scale Bitcoin miners could halt for a while, and reallocate their rigs for distributed computation?
Or am I naive to think that this should be a common interest?

BitGo: "While expected, still a bit unbelievable. First they were fighting on-chain scaling (thus addition of new privacy features), the next step would be adding AML to the protocol level. Well done, Bitcoin Core and “economical majority”! Shame on you, Bitcoin miners for allowing this."

Iranian Bitcoiners Risk Fines, Jail Time as Government Regulates Mining

Iranian Bitcoiners Risk Fines, Jail Time as Government Regulates Mining

News by Coindesk: Leigh Cuen
The Iranian government has been cracking down on cryptocurrency mining operations over the past three months, pending new legislation for formal mining licenses.
Since authorities have not officially approved a mining license process, several sources told CoinDesk that bitcoin miners are now operating in a climate of perpetual fear.
In rare cases, they can be jailed for continuing to operate. More often, they face exorbitant fines or have their equipment sealed off.
“If the government learns about my equipment, they’ll seal it and turn it off,” one small-scale bitcoin miner, operating just 15 machines in Tehran, told CoinDesk, adding:
“I’d be arrested. … After six months of waiting [for licensing regulations], they still want to make miners seem like criminals.”
Another professional bitcoin miner estimated the government has confiscated 80,000 mining devices over the past four months. It’s hard to say what the real numbers are, since they are not publicized. But this second bitcoiner alone lost access to thousands of machines, as he was operating an industrial farm connected directly to a power plant. He said 30 households lost their income when the government shut down his operation.
Plus, he says he personally knows more than 15 bitcoiners who were jailed.
“We have to wait for the Ministry of Energy, and the [new] regulations, to make a protocol with tariffs for our business,” he said.
An anonymous bitcoin developer in Tehran, who often works with miners, told CoinDesk many bitcoiners surrender the deeds to their homes to get out of jail, because the fines themselves can be worth more than their annual salaries. He said the fines range from $2,000–5,000 per machine, which is several times their retail value.
“There are also fines on the price for electricity,” he added, explaining that the electricity fines are often four times the annual cost of power for the machines. For example, if the mining farm paid $5,000 for a whole year of electricity, the fine for using a subsidized electricity source could be $20,000.
In Iran, the state-controlled electricity prices vary according to use-cases and the category for bitcoin mining has yet to be formally established.
As for the second miner who lost access to his industrial-sized operation, he told CoinDesk his company has an “open case” in court over a fine. He expected to be charged twice the market value for thousands of machines. But he’s unsure how he will be able to pay.

Smuggled equipment

These bitcoin miners face compliance hurdles from multiple agencies, related to both smuggled equipment and subsidized electricity fees.
The anonymous developer said most computer equipment and luxury goods are technically smuggled, from air conditioners to televisions sets. He said foreign grey market products are usually cheaper and higher quality than those sold through official retailers.
“If [the government] really wanted to fine all the people in the country using or selling smuggled merchandise, they’d have to fine everyone in this country,” he said, adding:
“Yet in just one area in the southern part of Tehran, a dozen [mining] farms were [recently] closed.”
As reported by a Tehran-based journalist for Bitcoin Magazine, the acute focus on finding bitcoin miners is wreaking havoc on the Iranian crypto community.
A survey of 600 Iranian bitcoiners, conducted over the past two weeks by the market research firm Gate Trade, found that 40 percent of respondents said the lack of regulatory clarity was their “biggest challenge related to bitcoin.”
Another miner operating near Tehran, also tapping into an industrial power plant, said up to at least 30 people associated with his farm haven’t had income for over a month. Plus, he said people with smaller, personal miners are afraid to move their equipment these days.
“If you were caught by the police having mining equipment in your car, your equipment would be seized and you would be charged with a penalty for handling or moving illegally imported machines,” the third miner said.
Indeed, local news outlet Fars News reported in July that several unnamed individuals were arrested in the southwestern city of Saveh for transporting smuggled mining equipment.

Power battles

Given this context, the growth of Iran’s bitcoin mining sector is screeching to a halt, with some bitcoiners taking small operations deeper into the proverbial underground and others halting completely.
Just like the second miner, the third mining farm operator’s machines are now sealed under government control, as he too has a pending court case.
Both this third miner and the developer said there is no evidence to suggest the government is mining bitcoin with confiscated equipment, and they hope it will remain that way.
To be fair, the third miner also said many people steal electricity for bitcoin mining, though he said his operation had a contract with a power plant. He personally doesn’t know anyone who went to jail over the summer. Most of his associates either lost access to their equipment or had to stop working.
“All we want, as people living in Iran, is for our government to understand the importance of this opportunity,” the third miner said, speaking to the hope that Iran will become a hub for bitcoin mining operations.
The second miner agreed. Imagining a worst-case scenario, he added:
“Otherwise, we’d have to sell [our equipment] like garbage.”

Satoshi quotes prove that the original bitcoin scaling plan was very clear from day one. And guess what ? it was not to have a centrally planned quota below market demand by the use of massive censorship and demonizing miners

An anonymous individual named Theymos controls the 2 main places where discussion happens: bitcointalkforums and bitcoin subreddit, and is known for censoring all discussion favoring certain improvement proposals mainly in the scaling debate. The mere fact that only 1 person can control and censor online social interactivity should be a big warning sign for any liberty minded individual.
I have no proof that this individual is linked to a certain company other than the fact that they both started to act in this space at about the same time, Blockstream was funded in 2014 and Theymos started censorship about rising the blocksize in 2015. Also note that the behavior of this individual serves the motives of the said company that explicitly explained that they plan on collecting fees on their own side-solution that the other (original) scaling solution would not allow them to collect.
The direction they are pushing is also allowing another company named Bitfury to de-anonymize transactions incredibly more easily. Bitfury and Blockstream have both supported the same path for bitcoin (segwit), and both profit from it or plan to do it.
The original scaling plan was however very clear, as per cited in the original whitepaper or satoshi himself:
The [current] cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions
= bitcoin is invented as digital cash for small casual transactions against the high-fees of the current system.
The proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. [...] They vote with their CPU power, expressing their acceptance of valid blocks by working on extending them and rejecting invalid blocks by refusing to work on them. Any needed rules and incentives can be enforced with this consensus mechanism
= proof of work is the only way to vote in the system = miners are to be trusted to choose the path of the network
We define an electronic coin as a chain of digital signatures.
= segwit destroys the very definition of bitcoin
With computer systems typically selling with 2GB of RAM as of 2008, and Moore's Law predicting current growth of 1.2GB per year, storage should not be a problem even if the block headers must be kept in memory
= Moore's Law ensures that we never reach a scaling limit
source for all of the above quotes:
It can be phased in, like: if (blocknumber > 115000) maxblocksize = largerlimit It can start being in versions way ahead, so by the time it reaches that block number and goes into effect, the older versions that don’t have it are already obsolete.
= satoshi wrote some code on how to prepare a hardfork to a bigger blocksize YEARS ago
“At first, most users would run network nodes, but as the network grows beyond a certain point, it would be left more and more to specialists with server farms of specialized hardware.” [...] Bitcoin generation should end up where it’s cheapest.
= satoshi envisioned asics, mining farms, and "specialized hardware" like asicboost, and that mining will end up in farms where it is cheap to mine
Bitcoin can already scale much larger than [Visa] with existing hardware for a fraction of the cost. It never really hits a scale ceiling.
satoshi in 2009, can it be any more clear ?

Good news Canada welcomes China cryptocurrency miners, let's go!

Quebec was fishing for tech giants but caught bitcoin miners.
At least that’s how David Vincent, business development director at electric utility Hydro Quebec, describes the results of a campaign launched in 2016 to lure the likes of Facebook, Amazon and Microsoft to build their data centers in the Canadian province.
The sales pitch was simple: the province offers plentiful, cheap and renewable electricity, along with cold weather and a politically stable environment.
And while Hydro Quebec has gotten plenty of bites from traditional data center operators, the company also quickly discovered those same traits are equally attractive for cryptocurrency mining operations.
Nonexistent just six months ago, interest in Quebec from commercial-scale bitcoin miners has skyrocketed, Vincent said, amid the surge in cryptocurrency prices and political uncertainty in other jurisdictions.
For Hydro Quebec, 35 cryptocurrency mining organizations are asking the company for information regarding connecting to the power grid there. Those companies now account 70 percent of the total wattage capacity in Hydro Quebec's development pipeline.
In an interview with CoinDesk, Vincent said:
“I have so much demand right now there’s no need for marketing. Pretty much every day I have a new one.”
And sentiments from others suggest what Hydro Quebec is seeing now is just the tip of the iceberg.
"Based on what I've seen in equipment purchase, real estate and power deals, things are exploding in Quebec," said Austin Hill, the former CEO of Blockstream, who is now investing in and backing some of the mining projects looking to Quebec.
Cheap and abundant
Cryptocurrency mining – the energy-intensive process by which new transactions are added to a blockchain – generally requires specialized hardware (either ASICs or GPUs) to solve complex mathematical puzzles. Because of the vast amount of computing power that's used, mining rigs generate a significant amount of heat, which is why mining operations look for colder environments to set up shop.
But it's not only the cold weather that's a draw for Quebec. The government's aggressive effort, during the post World War II era, to build dams in its northern regions has proven enticing enough to pull mining operators away from existing bases that already have weather on their side.
Because of that work, Quebec has become one of the largest hydroelectric power producers in the world. Hydro Electric, with 37,000 megawatts of installed electricity capacity, routinely produces at surplus levels and is thus able to offer some of the lowest rates in North America to its commercial customers.
For data centers, Hydro Quebec charges as low 2.48 cents (in USD) per kilowatt hour, and 3.94 cents per kilowatt-hour for bitcoin miners (the slight increase for the latter due to mining operations' smaller job creation and economic development footprint), Vincent said. These rates are anywhere from 50 percent to three times lower than in comparable parts of North America, according to data compiled by Hydro Quebec.
Historical consistency in pricing over time, and the assurance that the rates are not simply teasers that will jump overnight, are a key part of the value proposition for cryptocurrency mining operations, Vincent said. He added:
"We always succeed at staying below inflation. It’s been like that since 1963 and it’s not going to change."
And while some have argued that cryptocurrency mining is environmentally degrading, there's a growing trend by these mining operations toward finding competitive advantage via greater energy efficiency and resource optimization.
"In some hotter environments, the current ASIC equipment ends up having a very short shelf life of around six to nine months because it gets so hot, and the cost of cooling it isn’t worth the cost of the equipment," Hill, who heads the Montreal-based Brudder Ventures, said, adding:
"It’s just easier to run it super hot, throw it away and buy a new one. It’s hugely wasteful."
And moving to cooler climates, like Quebec, could help.
Political stability
Another driver behind Quebec’s accidental emergence as a cryptocurrency mining hub is that miners are increasingly looking for stable political environments where they can deploy their capital investments and plan their business efforts four to five years in advance with a higher degree of confidence.
While several of Hydro Quebec's interested parties are based in North America, a significant number of mining organizations hail from countries, notably China, where the landscape for cryptocurrency mining, and cryptocurrencies in general, has become cloudier.
In China, for instance, rumors have been surfacing that the government plans on withdrawing preferential benefits such as cheap electricity and tax deductions to bitcoin mining operations. Plus, the People's Bank of China has been one of the more aggressive regulators in the world when it comes to cryptocurrency, most recently issuing a ban on initial coin offerings and moving to shut down bitcoin exchanges.
Notably, Vincent said mining interest in Quebec began to tick upward significantly last fall after these moves by China.
He told CoinDesk:
"They don’t say it like that, but the fact that the rush of the demand came at pretty much the same time they were having problems in their previous jurisdiction, we could think there was a correlation."
These concerns, along with a steady flow of reports about mining equipment seizures, kidnappings and game-playing by corrupt public officials in places like Venezuela, could make setting up shop in places where these risks are minimal more important than ever for mining operators.
A good problem
While Hydro Quebec is still, admittedly, trying to fully grasp this new class of customers, it’s been more than willing to roll out the welcome mat for them because of the enormity of the requests, not to mention the 24/7 nature of their operations.
To show mining operation's scale, Vincent compared them to Hydro Quebec's other customers.
Its smallest commercial customers, such as the Montreal Canadiens’ hockey arena, require five megawatts of electricity and a typical data center requires 30 to 60 megawatts. By contrast, "the top-three to top-five miners in world, most of them are talking to us, and the demand that they have right now is around 200 to 300 megawatts," he said. "It’s huge."
But with an industry as volatile as cryptocurrency, nothing is fully set in stone, and as a risk-averse, publicly owned utility, Hydro Quebec is minimizing its exposure by requiring miners to foot the upfront cost of the power connection and arrange a line of credit from a third party large enough to offset any losses in the event of something dire.
"The question for us is: is this a trend that will continue to stay at least as strong as it is right now?" Vincent said.
But for now, the biggest problem facing Hydro Quebec is finding enough buildings and locations that are suitable to be used as mining farms, as well as hiring more people who can help meet all of the requests from these types of potential clients, as quickly as they are coming in.
"[The miners] have this impression that they’re losing money every day, so they’re asking for big buildings with big interconnections and they want it tomorrow," Vincent said, concluding:
"We have the capacity, but we’re not used to having so much big demand like this. It’s a good problem to have."

PSA: The top 51% of hash LOVES SCALING. It is incentivized to innovate, to handle more & more TXs. TO CUT OFF inefficient/slow miners bc it DOUBLES their profit! At the same time, this creates incentive for the slow ones to join the 51% quickly and upgrade. BITCOIN IS RUTHLESS COMPETITION.

"The scaling argument was ridiculous at first, and now it's sinister. Core wants to take transactions away from miners to give to their banking buddies - crippling Bitcoin to only be able to do settlements. They are destroying Satoshi's vision. SegwitCoin is Bankcoin, not Bitcoin" ~ u/ZeroFucksG1v3n
SegWit introduces a large amount of complexity, technical debt that will make it harder for others to contribute, locking in the "Core" devs. This is something that I see a lot in older coders who are afraid of becoming irrelevant and try to "lock in" their relevancy by becoming maintainers of a critical but obscure infrastructure.
Plus SegWit really is not a soft-fork, but a hard-fork, since you can't run an older node anymore and still even participate in validating transactions, all old nodes become obsolete.
You won't have any choice over whether you want to accept "anyonecanspend" tx without signatures included unless you literally run a full node on the old repo tag, and even then your node won't actually be participating in the network anymore except as a relay, not a validator.
It's a major technical change, introducing a large new attack surface, and I don't think it's prudent to force it through this way in a $10B $15B economy.
It reeks of centralized control, and I especially don't trust would-be economists and religious zealots like GMaxwell and Luke Jr. to have that control. Nobody should, it's supposed to be peer-to-peer Satoshi consensus.
I also think that if a sidechain implementation does come out, it should be from a team that doesn't have the conflicting interest of also being the maintainers of the "Core", especially if that group is holding the blocksize down for the business interests of a large banking collaborative who pays their salary.
To me, this represents undue control and influence of the banking community on Bitcoin, and their interests are to make Bitcoin into a settlement layer only, not a payment layer or a store of value for civilians.
The bankers largely agree with the modern "helicopter money" theories of Bernanke, loosely based on Keynesian economic theory, as opposed to the Satoshi viewpoint of Austrian/Viennese economic theory.
The bankers are aligned with the governments, they want people using fiat, they are literally opposed to any safe store of value as it negates their ability to "stimulate" people into spending by devaluing the currency, which is their excuse to keep printing money and essentially enslaving everyone else via that mechanism. The bankers and governments want people using fiat, and the "Core" have even told people to use VISA instead of Bitcoin!
Finally, scaling itself. The whole scaling argument was ridiculous at first, and now it's turned sinister. Moore's law predicts a doubling of memory capacity on a given size of chip every 18 months, and Neilsen's law predicts a doubling of the fastest speeds achievable in a communication network every 12 months. Using these laws, we can extrapolate that bitcoin would be just fine with an immediate increase to 8MB max blocksize, and a 30% geometric growth curve forever, and have a decreasing storage capacity signature and network propagation delay over time, forever. Therefore, the whole debate is meaningless, it's completely political.
The bankers bought out Core, and now they are blocking scaling so they can try to force everyone to use Lightning Network instead of Bitcoin.
Core is literally trying to take all the transactions away from the miners and give it to their banking buddies, while crippling Bitcoin to only be able to do banking settlements. They are destroying Satoshi's vision. SegwitCoin is Bankcoin, not Bitcoin.
