Bitcoin mining pool OCEAN revealed that a configuration issue caused some miners to unknowingly mine on the stalled BIP-110 chain for roughly 18 hours. The pool said it will distribute approximately 0.3 bitcoin in direct rebate payments to match the rewards miners would have earned on the main chain.

OCEAN confirmed that for roughly 18 hours, miners using its Stratum templates who believed their hashrate was directed to the non-BIP-110 chain were actually contributing to the BIP-110 side of the split.
To ensure no miner is disadvantaged, OCEAN said it will issue direct bitcoin rebate payments based on rewards miners would have earned on the non-BIP-110 chain during that period.
“Approximately 0.3 BTC will be distributed, with payments completed within the next 72 hours. We’ll publish the transaction details once the payments are sent,” OCEAN said in an update.
The pool added that its default endpoint has been restored to the non-BIP-110 chain, though both mining options remain available, allowing operators to explicitly choose where to direct their hashpower.
While many pools adopted a wait-and-see approach, OCEAN took a bold step by adding two new Stratum endpoints bip110.mine.ocean.xyz port 3110 and http://no-signal.mine.ocean.xyz port 3000 on July 8. At the time, OCEAN framed additions as an option to signal for miners who are unable to use DATUM or who need a failover.
