Is there any documentation on how algorand computes block hashes?
Usually on Algorand, everything is serialized using a canonical version of msgpack/messagepack (canonical means that zero values are omitted and keys are alphabetically sorted).
prefix || msgpack_of_data
where || represents concatenationspecs/crypto.md at master · algorandfoundation/specs · GitHub / go-algorand/hash.go at 2bc55c06f4dacf247b93a15f47530f57b4925d28 · algorand/go-algorand · GitHub
You can find details of Block serialization there:
