Web Proofs on Ethereum with vlayer
summary
vlayer notarizes HTTP responses using TLS Notary and a web prover server that runs an MPC with a notary, then exchanges the large web proof for a compressed ZK proof that an EVM contract verifies. Example fetches GitHub GraphQL, proves merged PR count for a repo, outputs repository, handle, contributions, extraction hash and notary fingerprint, and the contract checks query hash and image ID against risk zero proofs. Works in dev mode (real ZK needs GPU), needs good internet, and struggles with payloads > ~30 KB.
