BIP-110 proposes a temporary soft fork to disable OP_SUCCESS opcodes in Tapscript, aiming to clean up 'junk data' on-chain. But critics warn this could hinder future Bitcoin soft fork upgrades by closing off upgrade paths that Taproot specifically kept open. What's really at stake here, and why is this proposal raising alarms?
Greg Sanders, Antoine Poinsot, and Steven Roose have published formal specifications for OP_TEMPLATEHASH and a bundle of rebindable signature opcodes that could reduce Lightning Network overhead, enable non-interactive Ark, and optimize DLCs.
Bitcoin Core merged PR #34219 on March 4, 2026, adding pubkey validation for MuSig2 pubnonce and partial signatures in PSBT deserialization. This improves security for multisig wallet users and hardware wallet integration.
Bitcoin's Taproot upgrade promised privacy and efficiency, but adoption has collapsed from 42% in 2024 to just 20% in 2025. Quantum fears and the Ordinals hangover are driving users back to older formats.
