https://docs.arweave.org/developers/server/http-api#transaction-signing Transaction signatures are generated by computing a merkle root of the SHA-384 hashes of transaction fields: format, owner, target, data_root, data_size, quantity, reward, last_tx, tags, then signing the hash. Signatures are RSA-PSS with SHA-256 as the hashing function.
