Double-Blind Proof of Existence for Decentralized Identities
Published 2023-01-01“…As a practical solution, we introduce the notion of Double Blind Proofs of Existence (DBPoE), which shows that an opened DID is committed in one of the constant-sized multi-generator Pedersen commitments (33 Bytes at 128-bit security), and nothing else. Hence, our DBPoE double-blinds identity holders and identity verifiers to mitigate private information leakage. …”
