Luke Dashjr exits OCEAN as BLAKE2b fork revives amid BIP-110 dispute

  • Luke Dashjr left OCEAN after Mummolin repurchased his equity as the BIP-110 minority fork resumed under BLAKE2b rules.
  • The fork split at Bitcoin block 961,632, restarted at block 961,640 and mined more than 800 blocks under a roughly 300 kB limit.
  • BIP-110 signaling reached 2.53%; the fork’s asset remained absent from centralized exchanges and major price aggregators.

Luke Dashjr resigned as chairman, chief technology officer and director of Bitcoin mining pool OCEAN after operator Mummolin Inc. repurchased all of his equity under an Aug. 29 joint statement describing the separation as mutual and driven by differing visions for Bitcoin mining. The departure coincided with the revival of the BIP-110 minority fork he advanced: after splitting from Bitcoin at block 961,632, mining through block 961,639 and stalling for 23 days, the chain resumed when Silent Wave mined block 961,640 under new BLAKE2b consensus rules and subsequently produced more than 800 blocks. The fork replaced SHA-256d proof of work, added a 164-byte block header and imposed a temporary block-size limit of about 300 kilobytes, or 800,000 weight units, until September 2027. Difficulty fell from 125 trillion to 30 million, a 99.99% reduction, while hashrate reached about 177 EH/s versus roughly 908 EH/s on Bitcoin’s main chain. Reports differ on activation timing and launch details, including a flag-day hard fork around 3 a.m. Eastern Time on Aug. 30 and expected software publication on Sept. 1. The asset was not listed on any centralized exchange, and CoinGecko and CoinMarketCap displayed no ticker. BIP-110 signaling reached only 2.53% against a 55% threshold, while OCEAN continued operating its non-custodial pool and DATUM protocol on Bitcoin’s main chain and Dashjr promoted decentralized mining through CONVOY.
