Three Things Make Sovrin Work

Decentralized Identifiers

DIDs provide pairwise identity for every relationship to prevent correlation.

DID Descriptor Objects link DIDs to public keys and end points

Verifiable Claims

Allow third parties to provide identity owners with credentials they can use just like they do offline.

Distributed Ledger

Global and public:

• nobody owns it

• everybody can use it

• anybody can improve it
