Bitcoin in a Taproot World
summary
Taproot makes multisig look like single-signature onchain by enabling Schnorr/FROST threshold sigs, cutting fees and hiding that a 2-of-3 or 3-of-5 policy exists. Work is now delivering RFCs, a Blockstream draft BIP for FROST key generation, and MuSig2/ZKP library support so production use moves from musig m-of-m to real threshold schemes and roast for adversarial settings. Examples: BitGo-style key-path day-to-day with script-path contingencies, AnchorWatch insurance custody experiments, Fedimint exploring federation models; toolchain gaps are closing and key rotation without an on-chain transaction becomes practical.
