Recompute it yourself

Each digest is a sha256 over the canonical JSON of its own entry, and each entry carries the digest of the one before it. Change one byte of a body and every seal after it stops matching.

digest = sha256(JSON.stringify(canonical({ seq, kind, body, slot, at, prev })))
canonical sorts object keys at every depth
entry[n].prev === entry[n-1].digest, and seq starts at 0

Every field, as JSON
