Bitcoin developer revives 2017 proof-of-work code as BIP-110 fallback

Chris Guida said the code was rebased onto the latest Bitcoin Knots as a last-resort option if miners are seen as blocking activation of the BIP-110 soft fork.

Fact Check
Chris Guida's own X post (@cguida6) directly confirms he rebased Luke Dashjr's 2017 proof-of-work change hardfork onto a recent Bitcoin Knots release as a contingency because miners are not signaling BIP-110. This primary statement is corroborated by two independent news outlets (CryptoBriefing and CryptoNews) that report the same core facts: 2017 origin, rebase onto Bitcoin Knots, last-resort framing, and the trigger of miners blocking BIP-110 activation. All sources are mutually consistent.

Summary

Bitcoin developer Chris Guida said he has reworked code from a 2017 proof-of-work change and adapted it to the latest version of Bitcoin Knots as a contingency if miners do not back BIP-110. The proposal is being treated as a last-resort option if major mining pools are judged not to support the soft fork, which would reduce the amount of data that can be stored in Bitcoin transactions and curb non-monetary uses such as Ordinals. Luke Dashjr said he hopes the measure is never used, adding in Korean, "만약의 사태에 대비해 미리 준비해 두는 것이 좋다." Supporters including Mechanic argued that preparing the code in advance could help deter miners from trying to steer Bitcoin's rules and reinforce the role of node operators.

Terms & Concepts
  • proof-of-work: A mechanism that secures a blockchain by requiring miners to expend computing power to produce valid blocks.
  • soft fork: A network upgrade that tightens rules while remaining compatible with older nodes.
  • Bitcoin Knots: A Bitcoin node software implementation maintained as an alternative to Bitcoin Core.
