At present all Sovrin ledger writes are permissioned. If you read the SGF, Transaction Authors (TAs) will still need to work with a Transaction Endorser (TE) to write to the ledger. Sovrin Ledger Contractural Roles (click to enlarge). Tags: sovrin identity governance gdpr privacy i4a.

Sovrin is a permissioned ledger, meaning it achieves consensus using a known set of validators—in this case, trusted institutions around the world. This is in contrast to permissionless ledgers like Bitcoin's blockchain that rely on validators who are not identified. policies for amending the PTF.

Identity systems that rely on a ledger have an algorithmic architecture. I'm using "ledger" as a generic term for any algorithmically controlled distributed consensus-based datastore including public blockchains, private blockchains, distributed file systems, and others.

given that it relies on a permissioned ledger. Of course, the question is raised in an attempt to determine whether or not an identity system based on a permissioned ledger can make a legitimate claim that it's self-sovereign. Bitcoin and other decentralized ledgers are, in fact, logically centralized.

The metasystem provides a universal means of discovering issuer identifiers and credential definitions in the ledger layer, and a universal protocol, called DIDComm, for connecting and sharing credentials in the agent layer. The Sovrin Stack comprises four layers: The Ledger Layer. Layer One: The Sovrin Public Ledger.

Sovrin is based on a permissioned distributed ledger. Permissioned means that there are known validators that achieve consensus on the distributed ledger. Because the Alpha Network is for conducting tests, we anticipate that the genesis blocks on the ledger will be reset once the testing is complete.

There are two primary components of how Sovrin operates: the design of the protocols and the operation of the ledger. Sovrin is built on a public permissioned blockchain. This means that anyone can use the Sovrin ledger, but consensus is achieved by a known set of validator nodes. The Sovrin blockchain is a good example.
