DID and SBT 详解「去中心化身份」赛道现状、生态项目与未来发展

Amber Group released four layers of DID ecosystem.

Four types of DID projects:

Off-chain identity

Verify and bind the real-world off-chain identity with the address.



BrightID is a social identity network that allows you to prove that you’re only using one account. It’s the holy grail of digital identity.

One human one ID, use Face recognition and Zoom to verify you are a human.

On-chain identity

Aggregate on-chain and off-chain information into one on-chain identity.



UniPass is a multi-chain unified crypto identity and your universal passport to the crypto world and metaverse.

Link information into one ID, including social media, wallets, etc.
