True Network utilises it's trustless nodes infra to permission-less compute reputation & attest creds cross-chain based on ETH storage proofs. True Network is interoperably and provide a verification layer to all ETH L2s using Beefy. They are also researching on hash-based systems for privacy preserving on-chain attestations along with encryption techniques to eliminate the need of the user to store the credentials by themselves in a wallet. Their work addresses pioneering development with the potential to improve EVM compatible chains.

Needs a third review due to the project age. It barely makes the 3 month viability mark.
