Worldcoin has announced the extension of its World ID to the Solana network through Wormhole. The main goal of this integration is to enable the protocol on Solana to verify the World ID of users who have already completed authentication on Ethereum. According to Wormhole, a new smart contract will be developed on Solana, called SolanaWorldIDProgram, which is responsible for verifying and storing the World ID state root and verifying proof of inclusion (Inclusion Proofs). SolanaWorldIDProgram and the Wormhole State Bridge Service from Ethereum to Solana provide a robust and scalable cross-chain authentication solution.
