On July 21, Worldcoin, an identity-centric crypto project co-founded by OpenAI CEO Sam Altman, announced the public release of World ID SDK. Worldcoin said that World ID SDK makes network, mobile and on-chain integration fast and simple, including web widgets (JS), developer portals, development simulators, examples, guides, etc. Given World ID's permissionless architecture, developers around the world can integrate with it for free. World ID is also designed to support existing open identity standards, already supporting OAuth 2.0 and OIDC (Open ID Connect), and will be able to support verifiable credentials (VC), decentralized identifiers (DID), and login with Ethereum (SIWE) in the future.
