Sovrin has three networks for self-sovereign identity.
Each network is based on Hyperledger Indy and each is made up of between 4 and 25 nodes which are operated by Sovrin Stewards.
The Sovrin Foundation acts as a Governance Authority and operates the network as a whole, monitoring and improving performance in support of its ‘Identity for All’ mission.
There are three networks in use:
MainNet (since 2017)
Public production network for scaling live SSI applications & services
You can learn how to use Sovrin MainNet here: https://sovrin.org/issue-credentials/.
StagingNet (since 2018)
Public test network for prototyping pre-production SSI applications & services
You can learn how to start developing here: https://sovrin.org/developers/.
BuilderNet (since 2019)
Pre-production testbed for Indy Networks code
