Adam Back warns BIP-110 could freeze BTC funds and risk a chain split
On March 17, 2026, Blockstream CEO Adam Back criticized Bitcoin Improvement Proposal BIP-110, saying it could undermine Bitcoin’s stability and neutrality. He argued the plan’s 12-month soft fork and 50% hash-rate activation threshold could freeze some existing outputs and increase the chance of a chain split. Back also said current node support is limited to roughly 2.4% to 4.5%, with major mining pools showing little interest.
