Superchain Highlights 🔴✨

Gitcoin Passport Introduces Onchain Stamps
Identity verification platform Gitcoin Passport introduced onchain stamps on OP Mainnet. An onchain stamp is a verifiable credential stored onchain. The solution uses  Ethereum Attestation Service (EAS) for its onchain data structure. EAS is an open-source tool for onchain and offchain attestations that is available for OP Stack chains. Credentials can be assigned by various identity providers. The system aggregates stamps and assigns weights based on their cost of forgery. Stamps were previously stored offchain and required developers to query the Gitcoin Passport API to read the Unique Humanity Scores.
