NEDID

NEDID is a decentralized identity platform developed as part of the NEDAO project in the Canton of Neuchâtel, Switzerland. The system implements Self-Sovereign Identity through smart contracts based on the ERC-1056 interface and Verifiable Claims principles. The technical infrastructure includes support for off-chain attributes stored on IPFS, allowing users to manage identity information like usernames, profile photos, and social media links, while utilizing DID-JWT for authentication.

The platform is being developed with support from the Canton of Neuchâtel and operates on the Ethereum network, specifically using the Goerli testnet to avoid transaction costs while demonstrating functionality. Key technical features include:

• Integration with the Snapshot platform for off-chain voting
• Mobile wallet application for portable identity management
• Support for zero-knowledge proofs for privacy-preserving verification
• Open source development through GitLab

While initially launched in 2023, NEDID continues to evolve as part of the broader NEDAO initiative, which aims to provide citizens, SMEs, and institutions with practical experience in decentralized technologies. The project demonstrates a practical implementation of decentralized identity infrastructure at a regional government level, though it remains in active development with ongoing beta testing and feature additions.
