i hope web security this semester. profesor explain oauth 2.0. the protocol that lets you log into an app using your google accont. i have use it a hundred time with out understanding it. the leture made me realise most of the internet identy layer run on two or three open standards that almost no body reads.

that lecture stayed in my head. then i read the technical specification section in Sign Protocol's documentation.

Sign Protocol implements OIDC4VCI for credential issuance. OpenID for Verifiable Credential Issuance. the same OpenID that powers Google login, extended to issue verifiable credentials to wallets. a government ID authority that already runs an OpenID identity system can issue. Sign Protocol attestations to citizens using the same infrastructure they already have. no full system replacement. extend what exists with a standards-compliant credential issuance layer on top.

$SIGN is at $0.033 today. market cap $53.3M. 1.6B circulating out of 10B max. 78% below ATH. April 1, 2026.sign spot link

building on OpenID means Sign Protocol plugs into existing government identity infrastructure instead of asking governments to replace it. that is the right adoption strategy.

do you think governments adopting Sign Protocol would issue credentials through existing OpenID systems or build a new issuance layer from scratch? tell me in comments.😊
