Two attempts to increase Bitcoin’s block size bound via hard forks — Bitcoin XT together with Bitcoin Classic — own got failed to gain much back upward inwards damage of network hashrate, but early on bitcoin advocate together with angel investor Roger Ver is non giving upward on the cause. Ver is currently testing a novel mining puddle at Bitcoin.com, together with he’s seat together a novel evolution squad to piece of employment on an alternative to Bitcoin Core, the reference implementation of the Bitcoin protocol.
Bitcoin Magazine late reached out to Ver to larn to a greater extent than details on his innovation to increase the block size bound yesteryear trend of a difficult fork.
A Work-in-Progress
According to Ver, his innovation for difficult forking Bitcoin is nonetheless a work-in-progress. “I nonetheless own got lots to a greater extent than enquiry together with thinking to do,” he told Bitcoin Magazine. “The kickoff footstep is to genuinely own got our puddle upward together with running. I intend yous volition encounter our kickoff block mined on the network this coming week.”
The Bitcoin.com mining puddle mined its kickoff block a few days afterwards Bitcoin Magazine reached out to Ver.
The electrical current mining puddle software is running Bitcoin Unlimited, but Ver says a specific innovation for increasing the Bitcoin block size has non been chosen at this time. With Bitcoin Unlimited, nodes are able to select the maximum size of the blocks they exercise together with convey every bit valid. According to 1 Bitcoin.com mining puddle developer, the puddle volition mine 1 megabyte blocks together with convey blocks every bit large every bit xvi megabytes for now.
When asked nigh an activation threshold for a difficult fork, Ver seemed to distance himself from the thought of increasing the block size bound without a large amount of back upward signaled yesteryear miners on the network. “Ultimately the threshold is ever 51 percent, but nosotros would also probable back upward something higher inwards companionship to essay to hold to a greater extent than cohesiveness amongst the community,” he said.
Ver is unable to publicly reveal the members of his alternative Bitcoin evolution squad at this time, although he recently stated during an episode of The Bitcoin Game that old Bitcoin Core Pb maintainer Gavin Andresen is non on the team.
In damage of how much hashing mightiness the puddle volition own got on mainnet, Ver told Bitcoin Magazine, “We volition start off amongst a rattling minor amount on mainnet to exam for a few blocks, together with and then grow speedily from there.”
Bitcoin Unlimited Forks Classic Off Testnet
Although the Bitcoin.com mining puddle entirely late went alive on the mainnet, the puddle has been operating on testnet for over a month. In fact, the Bitcoin.com mining puddle forked Bitcoin Classic off of the testnet because Bitcoin Unlimited signals back upward for BIP 109 without genuinely implementing the total laid of rules inwards that specific proposal.
“I would recommend reading the discussions that already took house on /r/btc nigh this,” said Ver when asked nigh this incident.
When Bitcoin Core contributor together with Blockstream CTO Greg Maxwell challenged Ver regarding the testnet fork together with the “consensus inconsistencies betwixt Bitcoin ‘Classic’ together with other implementations are directly causing Classic to reject the testnet chain amongst most work,” Ver pointed out, “We are testing on testnet. That’s what testnet is for.”
Bitcoin Unlimited has been promoted every bit production-ready software for at to the lowest degree one-half a year, which is 1 of the reasons why to a greater extent than or less Bitcoin Core contributors own got been seeking farther clarification on just what was beingness tested amongst Ver’s testnet mining pool.
“[Bitcoin Unlimited] together with [Bitcoin] Classic both claim to back upward the same consensus rules (BIP109), but are diverged together with volition non portion the same testnet anymore — the whole holler for of a consensus organization is to come upward to consensus together with [Bitcoin Unlimited] together with [Bitcoin] Classic volition reliably neglect to exercise therefore on testnet,” commented Maxwell.
Bitcoin Unlimited developer Andrew Stone shared his views on the testnet fork inwards a weblog post. “Bitcoin Unlimited's ‘excessive block’ together with ‘excessive convey depth’ algorithm is non simply an arbitrary pick — it’s the optimal pick rational software tin brand inwards an untrusted network,” he wrote. “In essence, it encourages the client's preferences to the extent that the client tin exercise so, but together with then follows the bulk when the client's preference is rejected.”
Scaling Bitcoin to Meet Customer Demand
In Ver’s opinion, the electrical current 1 megabyte block size bound is preventing farther adoption of Bitcoin every bit a digital cash system. “As someone who has fifteen years of experience scaling enterprise networks before my involvement inwards Bitcoin, at that topographic point is no dubiousness inwards my hear that the network tin grip significantly larger than 2 megabytes blocks today,” he stated.
In fact, inwards the aforementioned interview on The Bitcoin Game, Ver claimed a block size bound of 20, 30, 40, or fifty-fifty 50 megabytes may survive fine. Influenza A virus subtype H5N1 key clarification on this disputation is that Ver does non believe excess block size would survive used correct away. “If the maximum block size today was laid at 50 megabytes, the blocks wouldn’t survive 50 megabytes,” he said. “The blocks would in all likelihood survive nigh a megabyte-and-a-half — perhaps 2 megabytes.”
In his comments to Bitcoin Magazine, Ver took this holler for further. “If at that topographic point was no bound on the block size at all today, most blocks would probable survive somewhere betwixt 1.2 megabytes together with iii megabytes at the moment.”
In the past, Bitcoin Core contributors, such every bit Blockstream’s Mark Friedenbach, own got argued that miners amongst improve connections own got an incentive to exercise bigger blocks. Influenza A virus subtype H5N1 miner could potentially materials blocks total of transactions inwards companionship to gain a competitive wages over their peers.
The key for Ver is to permit Bitcoin to scale inwards tandem amongst client demand. He does non wish to encounter potential users movement away from Bitcoin due to its “lack of scalability today.”
“Sadly this is already happening on a large scale,” said Ver. “But the electrical current [Bitcoin Core] evolution squad doesn’t seem to realize this or care. Some of them were fifty-fifty openly advocating that people travel credit cards instead of Bitcoin at a local Silicon Valley Meetup before this year.”
“I experience disturbed that to a greater extent than or less would consider it traitorous to refer that at that topographic point be systems other than Bitcoin that solve problems that Bitcoin doesn't,” said LedgerX Bitcoin developer together with Bitcoin Core contributor Bryan Bishop when asked to comment on Ver’s reaction to the views expressed at Silicon Valley Meetup.
To some, the thought of using a decentralized system, such every bit Bitcoin, to purchase a morning time java at Starbucks doesn’t brand much sense. There are tradeoffs when switching betwixt centralized payment providers, such every bit Visa or Mastercard, together with Bitcoin, together with it’s unclear if at that topographic point is much holler for to paying for a morning time java on a organization where the top dog value suggestion is censorship resistance.
In 2013, at that topographic point was a belief inwards the Bitcoin community that the average someone would before long brand all of their purchases via the peer-to-peer digital cash system, but the reality is — at to the lowest degree upward to this holler for — that normal people don’t seem to own got whatever wish to travel Bitcoin for everyday purchases. Last year, Blockchain Capital Managing Partner Brock Pierce noted consumer adoption of Bitcoin could survive a five– to twenty-year process.
Due to the 10-minute confirmation time associated amongst Bitcoin blocks, to a greater extent than or less tell that the peer-to-peer digital cash organization is non suitable for purchases at brick-and-mortar stores. The Bitcoin Core scaling roadmap includes layer-2 solutions, such every bit the Lightning Network, which permit for essentially instant confirmations at footling to no cost. Others encounter zero-confirmation transactions every bit useful for physical retail stores, but these unconfirmed transactions also come upward amongst risks.
There are potential risks amongst the Lightning Network every bit well, but these risks tin survive mitigated via Maxwell’s timestop proposal, which is outlined inwards an updated version of the Lightning Network white paper.
In his in conclusion remarks, Ver made his long-term goals for bitcoin clear. “I’m interested inwards edifice a currency to challenger the Dollar, the Euro, together with the Yen,” he said. “Bitcoin volition demand to scale via many dissimilar ways inwards companionship to achieve that.”
