What happened

Bitcoin’s BIP-110 data-limiting soft fork attempt entered mandatory signaling with under 3% miner support. The attempt mined two blocks and then stopped, while the main Bitcoin chain moved ahead.

Its backers split onto a minority chain. The episode has also revived discussion of a possible hard-fork fallback, according to the supplied record.

Why it matters

The event put a block-space governance dispute into a live chain split, even though the minority chain appears weak. It shows that enforcing nodes can struggle to carry a change without miner backing.

The immediate receipt to watch is whether minority-chain hashrate persists or changes, alongside any further hard-fork fallback discussion. Those signals would indicate whether renewed split risk is developing.

What to watch

Watch minority-chain hashrate and any further discussion of a hard-fork fallback.
