Luke Dashjr exits Ocean mining pool after dispute over Bitcoin upgrade proposal

Veteran Bitcoin developer Luke Dashjr has separated from OCEAN Mining, resigning as chairman, CTO, and director, while parent company Mummolin Inc. repurchased his equity. The mutual split follows a governance dispute over the failed BIP-110 proposal, which sought to restrict non-financial data on the blockchain but only achieved 2.6% hashrate support. While OCEAN continues its non-custodial operations at 25.33 EH/s, Dashjr plans to launch a new mining venture called CONVOY.

Luke Dashjr OCEAN exit

• ▪Luke Dashjr separated from OCEAN Mining by mutual agreement, resigning as chairman, chief technology officer, and director, while parent company Mummolin Inc. repurchased all of his equity.
• ▪The separation of Luke Dashjr from OCEAN Mining was announced in a joint statement on August 29, 2026, with both parties citing differing visions for Bitcoin mining following recent protocol developments.

BIP-110 miner signaling failure

• ▪The Bitcoin Improvement Proposal 110, which sought temporary consensus restrictions on non-financial data embedded in Bitcoin transactions, failed to attract broad miner support, peaking at roughly 2.6% of network hashrate.
• ▪Luke Dashjr took a sabbatical from his chairman and chief technology officer responsibilities at OCEAN Mining and was removed as a Bitcoin Improvement Proposal repository editor amid disagreements over BIP-110.
• ▪The minority branch of the BIP-110 fork produced only two blocks before stalling after enforcing nodes began rejecting non-signaling blocks at height 961,632.

OCEAN hashrate operational continuity

• ▪OCEAN Mining continues to operate its transparent, non-custodial mining pool, which accounted for approximately 2.88% of Bitcoin blocks over the trailing week with an estimated hashrate of 25.33 exahashes per second.
• ▪OCEAN Mining has not announced replacements for Luke Dashjr's executive or board positions following his departure.
• ▪Mummolin Inc. launched OCEAN Mining in November 2023 after raising $6.2 million in seed funding led by Jack Dorsey, alongside Accomplice and Barefoot Bitcoin Fund.

CONVOY mining venture launch

• ▪Luke Dashjr plans to launch a new Bitcoin mining venture called CONVOY following his departure from OCEAN Mining.
• ▪As of August 30, 2026, CONVOY had not disclosed details regarding its operating pool, participating miners, infrastructure, fees, launch schedule, or block-template policy.

Bitcoin mining pool governance

• ▪The BIP-110 dispute highlighted a central governance tension where mining pool operators establish default policies while individual miners can bypass them using decentralized protocols.
• ▪The broader Bitcoin mining market remains highly concentrated, with Foundry USA, AntPool, and F2Pool producing well over half of recent blocks.

DATUM protocol miner autonomy

• ▪OCEAN Mining added dedicated BIP-110 and no-signal endpoints in July 2026, then returned its default endpoint to the non-BIP-110 chain on August 9, 2026, while keeping both options active.
• ▪A miner named Simple Mining demonstrated DATUM's autonomy by producing block 961,634 without signaling support for BIP-110, despite OCEAN Mining supporting the proposal by default.
• ▪OCEAN Mining's Decentralized Alternative Templates for Universal Mining protocol, known as DATUM, allows individual miners to make transaction-selection decisions independently from the pool's default policy.
