Michael Saylor has identified BIP-110 as one of the most significant remaining risks facing Bitcoin, as debate intensifies around the proposal’s controversial activation threshold.

BIP-110 proposes a 55% hash power signaling requirement for activation—lower than the thresholds used in previous upgrades—raising concerns among some developers and market participants about potential governance vulnerabilities.

Michael Saylor flags BIP-110 as a key Bitcoin risk as debate grows over its 55% hash power activation threshold, with Ocean mining the first signaling block in 2026.

According to NS3.AI, the mining pool Ocean mined the first block signaling support for BIP-110 in March 2026. Since then, the signaling process has continued steadily, signaling growing engagement from miners as the network approaches a possible activation decision later this year.

Saylor’s remarks underscore broader concerns about how protocol changes are approved within Bitcoin’s decentralized ecosystem. Critics argue that a lower activation threshold could allow a slim majority of miners to push through contentious upgrades, while supporters say it enables faster innovation and avoids prolonged gridlock.

As signaling progresses, the BIP-110 debate is shaping up to be a critical test of Bitcoin’s governance model—one that could influence how future upgrades are proposed, debated, and ultimately adopted.
