Luke Dashjr has left OCEAN Mining, resigning as chairman, chief technology officer, and director. Mummolin Inc., OCEAN's parent company, repurchased all of his equity in what both sides described as a mutually agreed separation announced on August 30, 2026.
The departure followed a contentious period surrounding BIP-110, a proposal that sought temporary restrictions on embedding non-financial data into Bitcoin transactions. The proposal failed to gain broad miner support, with signaling peaking at approximately 2.6% of network hashrate, far below the 55% threshold supporters sought.
During the dispute, enforcing nodes began rejecting blocks that did not signal support for BIP-110. A minority fork produced only two blocks before stalling, while Bitcoin's dominant chain continued normally, demonstrating the proposal's limited adoption among miners. OCEAN had supported BIP-110 by default but operated its Decentralized Alternative Templates for Universal Mining protocol, which gave individual miners control over their block templates. This structure allowed miners to make independent transaction-selection decisions, and one miner connected to OCEAN produced a block without signaling BIP-110 support.
Dashjr subsequently took a sabbatical from his chairman and CTO responsibilities and was removed as a Bitcoin Improvement Proposal repository editor amid disagreements over BIP-110 and editorial governance.
OCEAN said its transparent, non-custodial mining model will continue operating despite the leadership change. The pool accounted for approximately 2.88% of Bitcoin blocks over the trailing week, with hashrate estimated at about 25.33 exahashes per second. The company has not announced replacements for Dashjr's positions.
Dashjr is moving to CONVOY, a separate venture focused on decentralizing Bitcoin mining, though details about its infrastructure, fees, and launch schedule have not been disclosed.
