Overview
DIA ZK is a zero-knowledge assurance layer built on top of DIA’s oracle stack. Alongside a data feed, it lets consumers verify that the data came from the expected source, moved through the expected delivery path, and satisfies a required condition, without revealing more of the underlying value than necessary. Instead of trusting a final number, consumers can verify the statement behind it. DIA ZK does not replace its oracle stack but it strengthens it by adding cryptographic proofs of authenticity, integrity, and privacy around the feeds DIA already delivers.Features
Source Authenticity
Proof that a data point came from the expected source and wasn’t tampered with, verified with zkTLS.
Selective Disclosure
Prove a value meets a condition, e.g.,
Reserve > $100M , without revealing the value itself.How it works
DIA sources data directly from its origin and processes it with transparent methodologies. DIA ZK adds a proof layer on top of that pipeline:- zkTLS proves that a piece of data was genuinely returned by a source over HTTPS, without exposing all of the underlying response.
- Threshold proofs verify that a value meets a condition while keeping the value private: the threshold is a public input, the actual value stays a private input.
- Proofs can be verified on-chain or off-chain, so both smart contracts and off-chain systems can check them.
Use cases
Stablecoins
Prove reserve sufficiency, validate collateral values, and verify issuer or custodian data while limiting unnecessary disclosure.
Vaults & Lending
Use authenticated values and private threshold proofs to verify collateral safety, liquidation readiness, and risk parameters.
Tokenized RWAs
Verify off-chain market data, NAV inputs, proof-of-backing, and asset administrator data.
Bitcoin DeFi
Prove backing of wrapped Bitcoin products, using source authenticity and reserve threshold proofs.
