vlayer Workshop
summary
Vlayer demonstrates four concrete ZK features for Solidity devs: Time Travel and Teleport let provers read historical and cross‑chain state (Ethereum, Base, Optimism, Sepolia) and return public inputs for on‑chain verification; Web Proofs notarize TLS sessions via a browser extension to ZK‑prove Revolut balances or a Twitter handle; Email Proofs parse DKIM headers into proofs. Uses Solidity provers/verifiers, Foundry tooling, templates, a CLI, live Twitter and Revolut demos, and a notary trust model with docs.
