Contracts of the Sismo Badge Minting Protocol
最后发布版本: alpha-testnet-upgrade-hydra-s1-accountbound-and-pythia-1-simple-attesters-01-13-2023 ( 2023-01-13 23:29:39)
This repository contains the smart contracts of the Sismo Protocol.
There are three core contracts:
-
core/AttestationsRegistry.sol
: The registry stores all attestations. It is owned by the governance that authorizes/unauthorize issuers to record in it -
core/Attester.sol
The standard abstract contract must be inherited by attesters. Attesters are issuers of attestations. They verify user requests and build attestations that will be recorded in the registry -
core/Badges.sol
Reads the registry. Stateless Non Transferable Token view of attestations (ERC1155)
It also contains implementations of attester in attesters/
:
-
HydraS1SimpleAttester.sol
: ZK Attester using the Hydra S1 Proving Scheme and the notion of nullifiers. Users must provide a ZK Proof along with their request to generate attestations -
HydraS1AccountboundAttester.sol
: Accountbound version of the Simple Hydra S1 Simple Attester. (Users can update at will where the attestation is stored)

Create a new Attester
To develop a new attester, you must inherit the core/Attester.sol
abstract contract and implement the following functions:
-
_verifyRequest(request, proofData)
: You must implement the user request verification against the proof provided by the user -
buildAttestations(request, proofData)
: You must build the attestations that will be recorded from a verified user request
Other optional hook functions that can be implemented:
-
_beforeRecordAttestations(request, proofData)
-
_afterRecordAttestations(request, proofData)
The /attesters/hydra-s1/HydraS1SimpleAttester.sol
is a good example of an attester implementing those functions.
A guide is offered in our documentation.
