Worldcoin has announced that it has expanded its World ID to the Solana network through Wormhole. The main goal of this integration is to enable protocols on Solana to verify user World IDs that have already been authenticated on Ethereum. According to Wormhole, a new smart contract called SolanaWorldIDProgram will be developed on Solana, which will be responsible for verifying and storing the World ID state root and verifying inclusion proofs. SolanaWorldIDProgram and the Wormhole State Bridge Service from Ethereum to Solana provide a powerful and scalable cross-chain identity verification solution.
