get_proof_for_blob

Retrieves a compound proof for a particular data blob given its on-chain address.

post

• Returns null if the blob does not exist.

• Returns an error if there was a database or RPC failure.

The proof shows that the indexer has returned a data blob whose content hasn’t been tampered with because it hashes into a blober account, which hashes into the bankhash at submission.
