How does Sovrin use Blockchain?

The Sovrin Network is the first public-permissioned blockchain designed as a global public utility exclusively to support self-sovereign identity and verifiable claims. Recent advancements in blockchain technology now allow every public key to have its own address, which is called a decentralized identifier (DID). A DID is stored on the public ledger along with a DID document containing the public key for the DID, any other public credentials the identity owner wishes to disclose publicly, and the network addresses for interaction.

Using the Sovrin Network, the identity owner controls the DID document by controlling the associated private key. The primary objects stored and updated on the Sovrin Network ledger are public DIDs, issuer credential definitions/schemas, and revocation updates.
