Introduction to zkTLS

The article argues that zkTLS, which lets users generate zero-knowledge proofs over TLS sessions, could let Ethereum applications verify most data accessible on the internet, beyond what oracles like Chainlink and Pyth provide. It describes three approaches to generating these proofs: MP-TLS using Multi-Party Computation with a notary, a TLS Proxy first implemented by the Reclaim Protocol team, and Trusted Execution Environments used by the Clique team. The text notes that the protocol is not fully secured by zero-knowledge proofs, and it says the MP-TLS implementation by the Privacy Scaling Exploration team supports data sizes up to around 61 KB.
