Hi, Im trying to reimplement generating a policy id from a policy script file in python. In the ledger specs it says that blake2b_224 is used for the hashing of multi-signature scripts, which I’m trying to replicate. I am using hashlib.blake2b like this: import hashlib m=hashlib.blake2b(digest_siz…

The short answer is that you need to prepend a single zero byte (“00”) to the CBOR serialization of the script before you apply blake2b_244 to it. I tried this out on your example and got the hash that cardano-cli transaction policyid computes. The longer answer is that here and here is the code th…
