Adam Back Warns BIP-110 Could Endanger Bitcoin Funds and Split the Chain

On March 17, 2026, Blockstream CEO Adam Back reiterated his opposition to Bitcoin Improvement Proposal BIP-110, which introduces a 12-month soft fork to remove on-chain data from protocols like Ordinals and Runes. He warns the changes could freeze certain transaction outputs, undermine Bitcoin's neutrality and store-of-value reputation, and even trigger a chain split if activated with only 50% hash rate support. With backing from roughly 2.4% to 4.5% of nodes, mostly using Bitcoin Knots, and no major mining pools on board, Back argues BIP-110 is effectively dead on arrival but highlights growing willingness to consider what he views as reckless measures against perceived spam.
