Luke Dashjr selects BLAKE2b as the new PoW algorithm for the BIP-110 chain

Luke Dashjr has selected BLAKE2b, using a random process, as the new proof-of-work algorithm for the BIP-110 chain, replacing the SHA-256d algorithm currently used by Bitcoin. According to ChainCatcher, BLAKE2b is better suited to mining with general-purpose CPUs and GPUs and is more CPU-friendly than SHA-256d, which would reduce the advantage held by existing Bitcoin ASIC miners. The report also referenced an earlier update saying Dashjr plans to formally activate the BIP-110 hard fork on Sept. 1, turning it into an independent blockchain and creating a new token distinct from Bitcoin. Separately, earlier reports said Dashjr had already lost his Bitcoin BIP editor permissions after they were revoked by the Bitcoin BIP editor team.

BIP-110 algorithm pick descends into dispute as Luke Dashjr proposes Testnet4 hash tie-breaker

The process of choosing a new proof-of-work algorithm for the BIP-110 fork has turned contentious after Luke Dashjr proposed using the last character of the first Testnet4 block hash found after 14:00 UTC to decide the winner. Peter Todd sharply criticized the idea, calling it 「an extremely crazy decision」 and arguing that Testnet4 blocks are cheap enough to mine that someone could repeatedly compute hashes to steer the outcome toward a preferred algorithm. The dispute deepened when multiple competing Testnet4 blocks appeared at the same height, raising fresh questions about whether the method could produce a fair result at all. In the BIP-110 Discord, Dashjr responded by saying, 「I’m even more confused.」 One participant said they had already ordered a Blake2b ASIC before the algorithm was finalized, then added, 「I guess I should cancel the order.」 Dashjr later acknowledged that Testnet4 was 「not a good way to do this」 and suggested that a valid Bitcoin block could be used instead. Giacomo Zucco said the episode shows that fairly 「restarting Bitcoin」 is now almost impossible. Bitcoin News reported the developments.

Luke Dashjr floats Sept. 1 as target date for BIP-110 proof-of-work hard fork

Bitcoin News said in a post on X that Bitcoin developer Luke Dashjr has proposed Sept. 1 as a potential target date for a hard fork tied to the BIP-110 proof-of-work change. He said the change should take place when BIP-110 “should have activated.” Dathon Ohm, the author of BIP-110, said the community is currently working on a proposal to modify Bitcoin’s proof-of-work algorithm. He also said the plan is to “make miners go away,” while accusing large mining pools of joining forces to oppose the BIP-110 initiative. Asked how the network would remain secure after existing miners exit, Ohm replied: “We will hire new miners.” The remarks, as cited by Bitcoin News, center on the proposed proof-of-work change, a possible Sept. 1 timeline, opposition from large mining pools, and questions around network security under the plan.
