Monorepository of contracts for the I am Human: proof of humanity protocol.

List of contracts:

• registry: implements the SBT Registry, documented in the NEP-393

Helper crates:

• sbt: set of traits, events and common functions for NEP-393 SBT Standard.
• cost: Common functions and constants to calculate gas and storage deposit for IAH registry calls.
• human_checker: Helper contract for integration tests. Notably, used for is_human_call.

Issuers:

• demo-issuer: basic SBT Issuer: contains a list of admins who are authorized to issue SBTs.
• community-sbt: Community Issuer of SBT tokens
• oracle: SBT Issuer which relays on an off-chain authority signing claims for issuing SBTs.

work in progress:

• soulbound-class: An algebraic class of tokens to efficiently query if a user have required subset of tokens.
• ubi: demo use case implementing universal basic income.

For details about creating and querying SBTs, and flow diagrams, see the NEP-393.

Actors:

• user: someone who wants to hold SBT
• issuer: a contract or an account which can issue SBTs and is whitelisted in a registry. Issuer is usually an entity which makes validation to mint a specific class of SBTs.
• registry: a contract which keeps balance of SBTs.

Whenever a new issuer is created, it needs a registry to mint tokens. Today, IAH registry is permissioned: the IAH Registry admin has to add a new issuer willing to mint tokens within IAH registry. In the future this may change and the process can be permission-less (any issuer will be able to mint tokens in the IAH registry).

Issuer calls registry.sbt_mint to mint new tokens. Each token must have specified class in it's metadata. See NEP-393 to learn more about SBT classes. The mint call panics, if a recipient already holds a token with a same class of a given issuer.

Anyone can query registry to check token supply or query tokens by issuer or by owner.

The IAH Registry supports the following extra queries, which are not part of the NEP-393 standard:

• is_human(account: AccountId) -> bool: returns true, if the given account is not human as specified by the registry criteria.

• SBT registry: Testnet registry is used to test the issuer behavior. For testing other integrations (eg polling, elections) use the testing-unstable version. Consult issuer contracts to validate which issuer is linked to which registry. We may consider adding migration to registry-1 to make it compatible with the latest version.
