Schnorr and Taproot Update

An effort to put a solid taproot proposal was done by developer Anthony Towns, the proposal was about segwit v1 with several adjustments to the current segwit version which included :

  • replacing the ECDSA Checksig/CheckMultiSign ops with new Schnorr ops
  • introducing a 33-byte v1 witness addresses that encode a secp256k1 ECC Point P that is spendable either by a direct schnorr signature of a script with the witness data and a taproot/merkle path to the script.
  • Versions for taproot scripts
  • Adding OP_MASK to support script masking via sighash
  • Making invalid opcodes upgradeable to have more flexibility than OP_NOP
