BIP-110’s Collapse: How Bitcoin’s Governance Gaps Let a Protocol Fork Die After Just Two Blocks

Bitcoin’s BIP-110 fork didn’t just fail. It collapsed before it could even gain traction, laying bare critical flaws in the network’s protocol governance model. The proposal entered mandatory signaling at block 961,632 with a paltry 2.53% miner support, far below the 55% threshold needed for activation. Nodes enforcing BIP-110 split off to form a minority chain, but it produced only two blocks in eight hours while the main chain advanced 48. This isn’t a minor setback. It’s a clear sign that the balance of power between developers and miners is broken.

The official data tells a straightforward story. Only 51 of the previous 2,016 blocks signaled support for BIP-110. Mining firm AntPool mined the first non-signaling block, which the main network accepted and BIP-110 nodes rejected. The minority chain inherited Bitcoin’s full mining difficulty but holds just 0.15% of the total hashpower, per Michael Saylor’s estimates. Its next difficulty adjustment is 350 days away, compared to 14 days for the main chain. Beneath these numbers lies a deeper conflict. BIP-110’s temporary block space restrictions targeted inscriptions and non-financial data, which supporters say raise node operator costs. But miners rely on these high-fee transactions for revenue, giving them a direct incentive to reject the proposal.

The rift between developers and miners isn’t new, but BIP-110’s failure amplifies its stakes. The minority chain faces insurmountable odds. Blocks arrive hours apart instead of every ten minutes. Transaction replay risk creates an attack vector, as signed transactions on the fork can be broadcast on the main chain. Critics like Saylor and Blockstream CEO Adam Back warned the proposal could fragment Bitcoin, and their concerns are playing out in real time. Developer Chris Guida has floated a proof-of-work change as a fallback, but no activation date has been set. This last-ditch effort won’t save the fork; it only highlights how disconnected the proposal’s backers are from the network’s operational reality.

Bitcoin’s near-miss with BIP-110 isn’t an isolated incident. It’s a warning that protocol-level division could become a recurring threat if governance doesn’t adapt. Decentralization shouldn’t mean gridlock, but right now, the network lacks a mechanism to reconcile developer ideals with miner incentives. Without meaningful reform, future proposals could split the chain again, eroding the trust that makes Bitcoin valuable.
