Liberating Off-Chain Data and Preserving User Privacy
summary
DECO is a privacy-preserving oracle layer that uses zero-knowledge proofs to prove facts like “bank balance > threshold” and to attest data came from an authentic source without revealing credentials or full transaction history. It outputs a computed credit score that is only the score on-chain, not raw records, and works with existing bank and DMV systems so it is legacy compatible. Use cases demonstrated: credit scoring, age/ID credentials, private data marketplaces, healthcare and climate data sharing.
