As of the 0.21 rebase we have Taproot in Elements. There is some folowup work we need to make this usable

  • update sighash algorithm (see doc: add document describing Taproot sighashes #933 for design doc)
  • add new opcodes to Tapscript (design doc forthcoming)
  • update CHECKSIGFROMSTACK to support variable-length messages
  • SIGHASH_NOINPUT?
  • add Taproot to dynafed headers
  • scope out pre-dynafed Taproot in blockheaders; can we softfork it and how much work would this be?
  • add Taproot descriptors (related: descriptors tracking issue Descriptors tracking issue #944)
  • add Taproot fields to PSET (needs own design doc / coordination with Bitcoin)
  • add Simplicity as a Tapleaf (related: simplicity tracking issue Simplicity tracking issue #945)
