Gitcoin Passport launches Onchain Stamps to combat witch attacks

ChainCatcher news, Gitcoin Passport announces the launch of Onchain Stamps. Gitcoin Passport holders can now transfer their Passport on-chain, seamlessly integrating with the Ethereum ecosystem.

Onchain Stamps are built on the Ethereum Attestation Service (EAS) and will initially be available on the OP mainnet, with plans to extend Gitcoin Passport to other EVM-compatible chains. Through interoperable attestations, projects can choose relevant attestations to resist Sybil attacks and authorization.
