Critics Warn BIP-110 Soft Fork Could Undermine Self-Custody and Put User Funds at Risk
AI Market Summary
BIP-110, a proposed Bitcoin soft fork targeting arbitrary data inscriptions and certain Taproot opcodes (e.g., OP_IF), is drawing criticism for potentially breaking self-custody workflows. Opponents warn users could still receive BTC to addresses using banned scripts, but those funds may become permanently unspendable, while legacy P2PK outputs face freeze and theft risks. With weak miner/node support and a 2026 enforcement target, governance uncertainty rises.

Bitcoin Improvement Proposal BIP-110 is seeking to introduce a soft fork that would block the use of arbitrary on-chain data employed by protocols such as Ordinals and Runes, and would also disable Taproot script opcodes including OP_IF. The change would affect Miniscript-based wallets and legacy P2PK outputs.
Critics argue the activation creates a sharp user-safety hazard: users could still send BTC to addresses derived from scripts that would become invalid under the new rules, but those funds could become permanently unspendable. More than 17,000 BTC is currently held in P2PK addresses; while spending would remain permitted, opponents warn of potential temporary freezes and increased theft risk during the transition.
BIP-110 is slated for mandatory activation in August 2026 at block 961632. Support among miners and nodes is currently described as limited. Opponents say the proposal directly challenges one of Bitcoin's core value propositions: secure self-custody.
