BIP-110 proposes modifying Bitcoin’s consensus mechanism by allowing miners to vote on valid blocks instead of strictly following the longest-chain rule, alongside limiting non-monetary data such as Ordinals and BRC-20 inscriptions. Supporters argue the proposal would reduce blockchain bloat, lower transaction fees, and reinforce Bitcoin’s primary role as a monetary network.

However, critics including Adam Back warn that such changes could introduce precedent for censorship and weaken Bitcoin’s neutrality. The proposal’s suggested 55% activation threshold—lower than the traditional 95%—has intensified debate, while industry figures like David Bailey have engaged publicly with both sides as the discussion continues ahead of potential activation decisions later in 2026.
