Understanding DID-Linked Resources

Understanding the context and construction of DID-Linked Resources (DLRs) on cheqd.

Overview

Our objective in building DID-Linked Resources on cheqd is to improve the way resources are stored, referenced and retrieved for our partners and the broader SSI community, in line with the existing W3C DID Core standard.

Support for AnonCreds using DID-Linked Resources

One of the functions of DID-Linked Resources is enabling support for AnonCreds on cheqd, where previously these were tied into the Hyperledger Indy ecosystem. Take a look at our AnonCreds documentation here:
