Strategy founder Michael Saylor published a lengthy essay Saturday rejecting BIP 110, a proposed Bitcoin softfork that would temporarily restrict several types of transactions carrying non-payment data.
Key Takeaways
Michael Saylor published 100 arguments against BIP 110 on July 18, 2026.BIP 110 uses a 55% miner threshold, far below the standard 95% in BIP 9.Saylor warns the softfork could cut miner fee revenue as block subsidies keep halving.Existing unspent transaction outputs created before activation would be grandfathered under the current rules. Saylor stressed that protection does not fully remove risk, since some pre-signed transaction workflows could still span the activation window and face new constraints, potentially forcing some users to migrate funds ahead of time.
Threshold and Activation ConcernsSaylor focused heavily on how BIP 110 would activate. The proposal uses a 55% miner-signaling threshold, well below the 95% threshold set in the standard BIP 9 process. It also removes the conventional timeout and FAILED state that lets a stalled proposal quietly expire, and adds a mandatory-signaling period ahead of guaranteed lock-in.
