SSI-specific blockchain projects
In this section, we describe ASBCs that are developed specifically for facilitating an SSI ecosystem.
Hyperledger Indy, Aries, Ursa, and AnonCreds
The Hyperledger identity stack consists of Indy, Aries, Ursa, and AnonCreds, which are flexible and can interoperate with other layers in the SSI stack:
- Hyperledger Indy was the Hyperledger foundation’s first blockchain framework that targeted identity use cases. It is a public permissioned blockchain specifically built for decentralized identity use cases. It can build and publish DIDs, VCs, and other similar elements of the blockchain.
- Hyperledger Ursa grew out of Hyperledger Indy as a separate project, which consists of cryptography components of Hyperledger Indy. Now it’s a separate project, used by not only Indy but also other projects that need cryptography components. Ursa contains the cryptographic components to be used by Indy, Aries, and any other project...
