CredChain: Take Control of Your Own Digital Identity 

UNSW Sydney Newsroom (Australia), Neil Martin, March 12, 2021

The CredChain Self-Sovereign Identity platform architecture developed by researchers at Australia's University of New South Wales (UNSW) School of Computer Science and Engineering uses blockchain to create, share, and verify cryptocurrency credentials securely. UNSW's Helen Paik and Salil Kanhere said CredChain could offer Key Sharding, the process of splitting complicated passwords into meaningless shards stored in different locations that can only be validated when recombined. Kanhere said, "If or when the key is lost, the owner can present enough pieces of the keys to the system to prove his identity and recover the original." Paik said CredChain offers decentralized identity authority via the blockchain, and “also ensures that when a credential is shared, the user can redact parts of the credential to minimize the private data being shared, while maintaining the validity of the credential."
