OCEAN said some miners who expected to mine on Bitcoin's legacy chain, including users who selected non-BIP-110 Stratum templates, were unintentionally routed to the BIP-110 chain for about 18 hours and that it plans to compensate affected miners with about 0.3 BTC based on expected legacy-chain returns. On Aug. 9, the pool restored its default stratum endpoint to the legacy chain while still allowing miners to choose BIP-110. Amid the dispute, Luke Dashjr said he is taking a sabbatical or leave from his OCEAN roles as chair and chief technology officer to focus on Bitcoin and related open-source development; OCEAN communications lead Bitcoin Mechanic also said he is temporarily stepping away. The BIP-110 minority chain stalled after producing only two blocks following a split at block height 961632, and Bitcoin Knots developers are now preparing a hard fork to reset proof-of-work, change the block header and add replay protection in an effort to keep that chain usable.
