Bitcoin Tapscript Disassembler
This project uses the opcodes from the btcd project,
and implements according to BIP 342 and BIP 341 a tapscript disassembler for witness entries of a pay to taproot Bitcoin transaction
input, similar to what can be found in the mempool.space project.
It's stipped down to the bone and pretty much only parses the most common version of tapscript as of now that has the leaf version being 0xc0 (and can ensure it is according to BIP specs).

Functions ¶
func DisassembleAsmTaprootScript ¶
DisassembleAsmTaprootScript tries to disassemble the taproot script from its ASM format into human readable script with OP codes names.
func GetWitnessesTaprootScriptAsm ¶
GetWitnessesTaprootScriptAsm return the part of the witness entries that contains the script and errors out if input the witnesses are from does not contains tapscript with the right version.
func RemoveWitnessAnnex ¶
RemoveWitnessAnnex removes the eventual annex from the slice of witnesses and return a new one.
func WitnessContainsCompatibleTapscript ¶
WitnessContainsTapscript, given the array of txinwitness from the bitcoin transaction input, will tell if it has a tapscript in the right version.
func WitnessLeafVersionIs0xc0 ¶
WitnessLeafVersionIs0xc0 tells if the witness (after annex is removed before passing it) has its leaf version being 0xc0.
