According to TechFlow, on July 9, Cointelegraph reported that Worldcoin, a cryptocurrency and digital identity project co-founded by OpenAI CEO Sam Altman, announced the launch of the World Chain developer preview. This version provides global developers with the opportunity to build the chain before the launch of the World Chain mainnet. Remco Bloemen, head of the Worldcoin Foundation protocol, said that through the World Chain developer preview, developers can deploy infrastructure on the "gated mainnet" because World Chain skips the testnet.

Developers have been testing World Chain on OP Stack, an open source development framework maintained by the Optimism Collective. World Chain is expected to be fully launched in 2024 and integrated with Worldcoin's identity protocol World ID, designed to enable real human transactions. The project is committed to providing an ecosystem where people can use a universal World ID as a global digital passport.
