Decentralized Identity DID 2.0 Standard Released: 1.2 Billion Users Can Self-Manage Digital Identities

W3C officially released the Decentralized Identity (DID) 2.0 standard on March 4. The new standard supports cross-platform identity recognition, allowing users to log into all supporting platforms with a single DID without creating separate accounts for each service.

Key improvements in DID 2.0 include: unified key management protocol, a privacy protection layer supporting zero-knowledge proofs, and compatibility with EU's eIDAS 2.0 regulation. The European Commission confirmed it will use DID 2.0 as one of the technical foundations for the EU Digital Identity Wallet.

India's Aadhaar system and Brazil's CPF system also announced support for DID 2.0 within the year. This means over 1.2 billion users worldwide will be able to access online services using self-managed digital identities.

W3C DID Working Group co-chair stated: 'DID 2.0's goal is to let users truly own their digital identity — just as you own your passport.'
