Luke Dashjr

Dashjr has contributed to Bitcoin Core, an open source software implementation for Bitcoin nodes, since the early 2010s. In 2013, a bug in version 0.8 of the software caused the Bitcoin blockchain to split into two incompatible chains. For several hours, some computers accepted blocks that others rejected, creating two separate transaction histories. Developers, including Dashjr, coordinated to quickly create a consensus upgrade that restored Bitcoin to a single chain. In 2023, Dashjr co-founded Ocean, a Bitcoin mining pool with the stated goal of decentralizing Bitcoin mining by giving miners the ability to select or construct their own block templates, reducing reliance on centralized pool operators. The company received seed funding from Jack Dorsey. It was formally launched at the Future of Bitcoin Mining Conference in El Salvador. In 2024, the pool established its global headquarters in El Salvador as part of its international expansion, citing the country's pro-Bitcoin regulatory environment. Following the decision, Dashjr stated, "El Salvador is on the leading edge of bitcoin and bitcoin mining adoption.
