Decentralized Identity: Who Are You On-Chain?

Principles of DID

DID solutions let users own and manage their identity natively on-chain, with wallets or NFTs as their primary profile. Standards like ERC-725 and verifiable credential schemas support social reputation, KYC, and pseudonymous actions.

Applications & New Frontiers

DID enables permissionless access to dApps, global “one-click” identity onboarding, and the migration away from Web2 login models. Combined with soulbound tokens and reputation protocols, DID forms the basis for web3 social, lending, and governance systems—where trust is transparent, portable, and user-controlled.
