Script and opcodes

Braun Brelin 29 Apr 2015, 17:12 UTC permalink original

Hi all,

I'm trying to find a good python script that will take the hash of the locking and unlocking tx scripts and output the actual op codes.

Any ideas where to look?

Thanks,

I have a library, pycoind (https://github.com/ricmoo/pycoind <https://github.com/ricmoo/pycoind>) you might find useful.

Quoted text (2 lines)

>>> import pycoind

>>> str(pycoind.script.Tokenizer('76a9143f320f852a51643d3ffbaa1f49bfe521dd97764a88ac'.decode('hex')))

'OP_DUP OP_HASH160 3f320f852a51643d3ffbaa1f49bfe521dd97764a OP_EQUALVERIFY OP_CHECKSIG'
