BIP-110 is approaching its first consequential activation boundary. The proposal enters mandatory signaling at block 961,632, currently projected around August 9, 2026. It locks in no later than block 963,648, roughly in late August, and activates its new transaction rules at block 965,664, currently projected for early September. BIP-110 uses a 55% signaling threshold and would enforce its restrictions for 52,416 blocks, approximately one year.
Bitcoin resolves consensus changes through coordination among miners, users, and nodes (note that anyone can be any combination of these three things). Miners choose which valid chain to extend. Users decide which chain’s coins, deposits, and payments they recognize. Nodes independently choose which rules they enforce. Durable consensus emerges whenever these groups converge on the same chain.
BIP-110 restricts large data pushes, oversized output scripts, undefined witness versions, Taproot annexes, deep Taproot control blocks, OP_SUCCESS opcodes, and certain Tapscript conditionals. It grandfathers UTXOs created before activation, while standard monetary uses remain compatible with its rules.
Most corporations don’t have to do anything
For most corporations, BIP-110 requires no action. Today, the typical corporate Bitcoin utility is as a store of value, as a long-duration treasury reserve asset. This use case is basically unaffected by the transaction features targeted by BIP-110.
