Description
fastsszwas upgraded in #324 and it changed the roots forConsensusData,SignedMessageandSSVMessage, which would be a fork.This
fastsszupgrade included a crucial hashing fix, replacingPutByteswithAppendin order to prevent double-merkleization inHashTreeRootmethods, thereby changing roots for[]bytefields exceeding 32 bytes.It's noted that Beacon spec tests appear unaffected by this change, as they don't contain fields exceeding the threshold for the double-merkleization bug. However, we don't know that Beacon messages are absolutely not impacted.
The changes that were done to preserve backwards-compatibility:
types.Contributionwas copied over fromv0.3.4spec.DataVersionis now being decremented in encodings and incremented in decodings, because all of the values were incremented by 1 in go-eth2-client.
