In depth
DECO—a privacy-preserving oracle technology developed at Cornell University and later acquired by Chainlink—allows data transmitted over the Internet to be confidentially attested to by oracles without the data being revealed to the public or to the oracle nodes themselves.[2]
From a high level, DECO involves a three-way interaction between various entities—a Web Server, a Prover, and a Verifier. The Prover (user or app running DECO Prover) queries the information from the Web Server (data provider), while the Verifier (Chainlink oracle running DECO Verifier) witnesses the interaction. By doing so, the Verifier can attest to the provenance of the communication between the Prover and the Web Server, knowing the endpoint that the prover interacted with along with an encrypted transcript of the interaction.
