Roughnecks, the mining group responsible for the only two blocks on Bitcoin's BIP-110 minority chain, has stopped mining under its name. The group also urged other miners to stand down, leaving the breakaway network stuck at two blocks beyond its split from Bitcoin.
The decision to stop
Roughnecks announced its decision to stop mining the breakaway chain and called on other miners to follow suit. The group didn't offer a detailed explanation, but the move is unambiguous: the mining operation that gave the minority chain its only blocks is walking away.
Without Roughnecks, the chain has no active miner. That's a critical problem, because a proof-of-work network needs miners to produce new blocks and confirm transactions. With none, the chain can't move forward.
A frozen network
The breakaway network remains at two blocks beyond its split point. That means it's been stuck there since Roughnecks stopped. Transactions that were waiting to be confirmed are now stranded, and the chain is effectively frozen in place.
It's a stark outcome for a split that never really got off the ground. Two blocks is all it managed, and now it's unlikely to get a third.
What this means for the split
The BIP-110 minority chain was a divergence from Bitcoin, but it never had broad support. Roughnecks was the only group mining it, and their exit is a clear signal that the split isn't viable. Even the group that started it isn't willing to keep it alive.
Roughnecks urged other miners to stand down, which suggests they want the chain to die quietly. Whether anyone else picks it up remains an open question, but with no blocks being mined and no clear incentive, the breakaway network looks finished.
