Luke Dashjr has left OCEAN Mining after resigning as chairman, chief technology officer, and director, ending both his leadership and ownership roles at the company. Mummolin Inc., OCEAN's parent company, repurchased all of his equity under a separation described by both sides as mutually agreed. Dashjr is a long-time Bitcoin Core developer, and his departure removes one of the most technically established figures from the leadership of a prominent mining pool.

The split follows a turbulent period surrounding BIP-110, which sought temporary consensus restrictions on certain non-financial data embedded in Bitcoin transactions. Neither side explicitly linked the departure to that proposal, but both cited differing visions for Bitcoin mining in the wake of recent protocol developments. The broader debate over non-financial data on Bitcoin—such as inscriptions popularized by Ordinals since early 2023—has divided parts of the community between those who view it as spam straying from Bitcoin's monetary purpose and those who consider it legitimate transaction activity.

Luke Dashjr's Exit Follows OCEAN's BIP-110 Mining Fallout

Those differences came into sharper focus during the BIP-110 debate. The proposal sought one-year restrictions on methods used to place images, text, and other non-financial data into Bitcoin transactions. It failed, however, to attract broad miner support, with signaling peaking at roughly 2.6% of network hashrate—far below the 55% threshold sought by supporters.

The disagreement became more visible when enforcing nodes began rejecting non-signaling blocks at height 961,632. The minority branch produced only two blocks before effectively stalling, while Bitcoin's dominant chain continued producing blocks normally, underscoring the proposal's limited mining support.

OCEAN supported BIP-110 by default, yet its Decentralized Alternative Templates for Universal Mining protocol, known as DATUM, gave individual miners control over their block templates. The system allowed miners to make transaction-selection decisions independently of the pool's default policy. That structure became significant when Simple Mining produced block 961,634 without signaling support for BIP-110, demonstrating that miners connected to the pool could reject its preferred policy while remaining within its shared payout structure.

The episode highlighted a central governance tension surrounding mining pools: operators can establish default policies, while technologies such as DATUM can return significant block-construction authority to individual miners. The outcome also served as a real-world test of how quickly minority chain splits resolve when they lack hashrate, with the dominant chain reorganizing the shorter branch out of consensus.

Dashjr later announced a sabbatical from his chairman and CTO responsibilities. Around the same period, he was removed as a Bitcoin Improvement Proposal repository editor amid disagreements over BIP-110 and editorial governance.

OCEAN Keeps Mining at 25.33 EH/s as Dashjr Moves to CONVOY

Despite the leadership change, OCEAN said its transparent, non-custodial mining model will continue operating. The company has not announced replacements for Dashjr's executive or board positions, leaving open the question of who will steer its technical direction.

The Bitcoin pool launched in November 2023 after Mummolin raised $6.2 million in seed funding led by Jack Dorsey, with Accomplice and Barefoot Bitcoin Fund also among the investors. From the outset, OCEAN was positioned as a successor to the Eligius mining pool, with direct payouts designed to reduce operator control over miners' block rewards. That infrastructure remains active following the equity buyback and management change.

According to Mempool.space data, OCEAN accounted for approximately 2.88% of Bitcoin blocks over the trailing week. Its hashrate for the week beginning Aug. 24 was estimated at about 25.33 exahashes per second.

While OCEAN continues operating, Dashjr is moving ahead with CONVOY, a separate venture focused on decentralizing Bitcoin mining. Details about its infrastructure, fees, participating miners, and launch schedule have not yet been disclosed. How CONVOY's approach differs from DATUM, and whether OCEAN names new leadership with a different stance on transaction-filtering policies, are among the open questions following the separation.

The separation ends Dashjr's ownership and leadership roles without disrupting OCEAN's existing mining operations, and it represents the most significant organizational change following the BIP-110 dispute, which failed to attract substantial miner support.
