An identity trust fabric (ITF) is a storage for cryptographic proofs of decentralized identities and verifiable credentials. An ITF enables decentralized trust between credential issuers, credential holders and service providers without relying on a centralized authority. An ITF can be built on a distributed ledger. A decentralized public key infrastructure (DPKI) is a component of an identity trust fabric.
