Abstract
An example operation may include one or more of generating, by an executing client, a blockchain transaction comprising an anonymous rating, a proof, a nullifier, and a root node value, receiving, by a smart contract, the blockchain transaction, the anonymous rating related to an authorizing client, verifying the proof with the root node value and the nullifier, verifying that the root node value is a current or a previous merkle tree root node value, adding the anonymous rating to a shared ledger, marking the nullifier as used, and storing the marked nullifier to the shared ledger.
