BIP 340 — Schnorr Signatures for secp256k1

Pieter Wuille ↔ Jonas Nick, Tim Ruffing

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 342 — Validation of Taproot Scripts

Pieter Wuille ↔ Jonas Nick, Anthony Towns

Specifies tapscript — the taproot script-path validation rules: Schnorr signature checks via OP_CHECKSIG/OP_CHECKSIGADD, OP_SUCCESS upgrade opcodes, and a per-input sigops budget.

BIP 341 — Taproot: SegWit Version 1 Spending Rules

Pieter Wuille ↔ Jonas Nick, Anthony Towns

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.
