Coinbase has introduced a new service, "Coinbase Verifications," which enables over 100 million users to authenticate their account and country credentials on the blockchain. This service, built on Coinbase's Layer 2 network called Base, employs the Ethereum Attestation Service. It achieved notable early adoption, with over 9,300 verifications on its first day. This initiative represents a significant advancement in decentralized identity (DID) standards. DID standards are crucial for web3 development, providing protection against Sybil attacks and enabling functionalities like unsecured loans and improved governance models. Despite its wide user base, this service is currently limited to the countries where Coinbase operates. The emergence of decentralized identity verification services from major entities like Coinbase indicates a growing trend in blockchain technology applications beyond traditional finance, potentially leading to a network of interoperable KYC providers in various sectors.
