BIP 340 — Schnorr Signatures for secp256k1

Schnorr signatures replacing ECDSA for Taproot. Provably secure, non-malleable, with efficient multi-signature aggregation — complex scripts become on-chain indistinguishable from simple payments.

BIP 341 — Taproot: SegWit Version 1 Spending Rules

Taproot — Bitcoin's most significant protocol upgrade since SegWit. Combines Schnorr (BIP 340) with MAST so complex spending conditions look like simple payments on-chain.
