Worldcoin brings World ID to Solana through Wormhole Grant 🚀

Worldcoin, Wormhole, and Solana Integration: Bringing Decentralized Identity to Solana

Wormhole contributors have received a grant from the Worldcoin Foundation to integrate World ID, a leading decentralized identity protocol, with Solana. This collaboration aims to enable Solana-based protocols to verify users’ World IDs originally authenticated on Ethereum, showcasing Wormhole’s multichain infrastructure’s versatility.

Overview of Worldcoin, Wormhole, and Solana

Worldcoin is a decentralized identity protocol designed to provide universal access to the digital economy. It utilizes zero-knowledge proofs to verify identities without compromising user privacy, with the core being the World ID that ensures secure identity verification using biometric data.

Wormhole is an interoperability protocol facilitating data and asset transfers across various blockchain networks. Launched in 2021, it supports over 30 blockchains and processes around $30 million in daily transactions, empowering developers to build applications operating across multiple blockchains.

Solana is renowned for its high performance, scalability, and low transaction costs, capable of handling up to 65,000 transactions per second (TPS) due to its innovative Proof of History (PoH) consensus mechanism, making it ideal for high-throughput decentralized applications.

Technical Integration Details

Objective: Enable Solana protocols to verify users’ World IDs authenticated on Ethereum.
Main Tasks:
- Reading, authenticating, and propagating the World ID state root from Ethereum to Solana.
- Allowing Solana protocols to authenticate users’ World IDs against the canonical state root stored on Ethereum.
Implementation:
- A new smart contract on Solana, the SolanaWorldIDProgram, will handle World ID state roots and inclusion proofs validation.
- Wormhole Queries and the Ethereum to Solana Wormhole State Bridge Service will facilitate authentication and data propagation.

Significance of Worldcoin x Wormhole Integration

Enhanced Security and Decentralization: Improves security and decentralization of identity verification across blockchain networks, preventing fraud and ensuring fairness.
Cross-Chain Interoperability: Demonstrates the power of cross-chain interoperability, allowing Solana applications to interact with Ethereum’s identity verification systems.
Financial Inclusion: By making identity verification more accessible and secure, it promotes financial inclusion by enabling more people to participate in the digital economy.

Final Thoughts

The integration of Worldcoin’s World ID with Solana, facilitated by Wormhole, is a significant advancement for Web3. It enhances security, decentralization, and cross-chain interoperability, fostering a more inclusive digital economy. The SolanaWorldIDProgram and Ethereum to Solana Wormhole State Bridge Service offer scalable solutions for cross-chain identity verification.

Hot Take: Embracing Decentralized Identity on Solana

By integrating World ID with Solana, the collaboration between Worldcoin, Wormhole, and Solana paves the way for secure, decentralized identity verification on the high-performance Solana blockchain, promoting cross-chain interoperability and financial inclusion in the digital economy.
