Bitcoin's BIP-110 soft fork has failed to gain the support it needed to activate, after Michael Saylor, Adam Back and Samson Mow spoke out against it. The proposal would have temporarily barred non-payment data such as images and text from the network for about a year.
BIP-110 has failed after it could not clear the signalling threshold miners needed to approve it. According to Farside UK: "BIP-110 has now failed to reach a 55% threshold" and can never reach it, the account wrote on X. Earlier in the week, the same account had warned that BIP-110 needed over 73% miner signalling for the rest of the period or it would never reach the 55% mark and would simply spin off into a new coin.
Saylor and other developers pushed back
The proposal was pitched as anti-spam, but it drew opposition from several prominent Bitcoin advocates, including Michael Saylor, Adam Back and JAN3 CEO Samson Mow. Some developers cautioned about a potential activation bug that could lead to a chain split, while others pointed out that images could still be recorded on the blockchain despite the proposed restrictions. Those objections raised doubts about whether the changes would achieve their stated goal.
What the proposal would have changed
BIP-110 was submitted to developers in late 2025 and authored by Dathon Ohm. It proposed seven temporary changes to consensus rules, lasting roughly one year, including limits on witness elements, restrictions on spending some undefined outputs, new limits on control block size, restrictions on spending certain outputs, and a ban on executable OP_IF and OP_NOTIF instructions in Tapscript. The stated goal was to mitigate blockchain spam and free up network resources for financial transactions.
Coins stored before the new rules took effect were to remain spendable under the proposal. Some pre-signed transactions prepared long in advance, however, could have become unusable if submitted during the restricted period — an issue developers said would need to be addressed.
