You can find in this section all the technical documentation of the Sismo Hub repository, the repository used for integrations on Sismo.
The Sismo Hub is powered by an off-chain infrastructure which:
Manages Badges metadata
Manages Groups: The infrastructure periodically generates off-chain Groups that aim to be reusable and sent on-chain for attesters like the HydraS1SimpleAttester. A Group of accounts bundles accounts that share some reputational or historical characteristics. Anyone can propose a new group to Sismo.
Creates Badges from a Group: The infrastructure will send the groups on-chain to the right attester so your generated group becomes the eligible group for a specific badge.
