Overview
Data Groups and how to create them.
The Factory is an interface to easily create Data Groups on the Sismo Hub infrastructure.
The Sismo Hub computes Merkle trees of groups, stores them in its database and publishes the Merkle tree roots onchain.
Onchain roots are the source of truth for back ends and smart contracts to verify whether a ZK proof is valid.
Data Sources are the accounts that users aggregate in their Data Vault. Currently supported Data Sources:
- Ethereum wallets/EVM accounts
- GitHub accounts
- Twitter accounts
- Telegram accounts
From imported Data Sources, Vault owners can generate ZK proofs of:
- Ownership of a specific Data Source (i.e, authentication)
- Inclusion of an owned Data Source in a Data Group (and a claim about its value in the group)
Data Groups are sets of Data Sources in which each Data Source has an associated value.
