Mining Halts on Bitcoin's Minority BIP-110 Fork Chain as Network Difficulty Drives the Splinter Project Into Deadlock

According to Arzdigital, published Sunday, 18 Mordad 1405 (August 9, 2026), the Roughnecks mining pool, the only pool to have mined blocks on bitcoin's contested minority BIP-110 fork chain, formally halted its activity on that network. The decision came after the pool mined just two blocks on the new chain, and the hashrate of Ocean, the fork's other backer pool, collapsed 96.5 percent, from 36 exahash to 1.25 exahash per second.

The core problem was that the new chain inherited the main Bitcoin network's 127.48 trillion difficulty level, calibrated for the entire global network's hashing power; as more miners exited, the time needed to mine the next block and reach a difficulty adjustment stretched to hundreds of days. Matteo Pellegrini, CEO of Club Orange and a backer of the plan, wrote on his X account that the retreat does not mean outright failure, but Luke Dashjr, a well known bitcoin developer, warned users running the incompatible software that they remain vulnerable to double-spend attacks. Arzdigital reported the fork has scant miner support and is effectively inactive at this point.
