The “Genesis” hard bifurcation of bitcoin Sv (i.e. BSV) should return to the original appearance of bitcoin protocol, but there seems to be a small problem in the middle.

BSV is the real bitcoin, and BTC is not bitcoin

At about 10 a.m. Beijing time on Tuesday, the BSV network was upgraded and the blockchain was “repaired back to the bitcoin protocol of Nakamoto vision” by adding the genesis rules. Jimmy Nguyen, chairman of the bitcoin Association and BSV supporter, said on twitter that “this historic moment” occurred on a block with a height of 620539.

In order to return to the original agreement of Nakamoto in 2009, genesis hard bifurcation removed the default block size limit. It is reported that this can liberate the transaction capacity limit and enhance the scalability on the chain.

The BSV team said on Tuesday that removing the above restrictions will help developers build “large-scale applications” on BSV and enable more business models. They changed the bitcoin script language and newly supported functions similar to smart contracts, so as to enhance the competitiveness of the project in the face of blockchains such as Ethereum.

Genesis was designed as the last major update on the BSV blockchain. According to a chain message sent by the BSV development team after the bifurcation, the upgrade is “locked and cannot be withdrawn”. They said: the invariance of basic protocols can save development resources, and companies no longer need to adjust technology frequently.

“Unintentional” division

About an hour after the update of Genesis, the research team of bitmex, the world’s largest cryptocurrency derivatives exchange, tweeted that “a considerable number of nodes have not completed the update and are still on the chain before the hard bifurcation”.

Initially, there was no chain split in BSV. But a few hours later, bitmex’s research team found that the original chain “increased by one block” before upgrading( Coindesk Chinese version note: chain splitting refers to the occurrence of multiple versions of a chain, which may be caused by the unexpected incompatibility between two different versions of all node software, or by miners competing for blocks. Generally, after hard bifurcation, there will be no block growth on the original chain.)

A spokesman for the BSV team confirmed to coindesk that the bifurcation was caused by a miner, but said “everything is in good condition” and the bitcoin association is actively contacting the miner.

Ruan said that this was not a “lasting chain bifurcation”, but an unintentional mistake of a miner “not upgrading the software to Genesis”. The current bitcoin mining association has no connection to this block.

“As Nakamoto described in the white paper, the blocks accidentally excavated on this error chain will not be extended. Nodes only recognize the longest chain, and only block after the longest chain. ” Ruan explained.

BSV has been controversial since it split from BCH in September 2018. Its main advocate, Craig Wright, has claimed to be the inventor of bitcoin – Nakamoto since 2016, but many people in the industry don’t think so.

BSV supporters believe that BSV is the real bitcoin.

A message on the chain after BSV bifurcation wrote: “bitcoin has finally changed back to bitcoin, and miners can write everything on this chain.”

The issue of whether BSV is bitcoin is still controversial. After twitter announced the addition of bitcoin Emoji expression on the platform last Friday, Calvin Ayre, a billionaire and BSV supporter, tweeted and shelled twitter founder Jack Dorsey, saying he was “in the wrong line”.

Al wrote: “BTC is not bitcoin. The lawsuit I learned about will be revealed this year. Your deviation from the truth will not bring any good end to twitter. “
