DID Network

Inspiration

There is a lot of valuable user data accumulated on the blockchain. We hope to build an open DID network by making full use of the on-chain data value and providing open functions such as authentication to serve more Web 3.0 application scenarios.

What it does

DID Network is a decentralized DID Network. We want to provide authentication services through a unified DID name service and build a network of connections between users.

How we built it

The DID profile page allows users to quickly know the on-chain behavior statistics of wallet addresses, such as profit and loss, NFT assets, and to follow the ones they are interested in, with support for multi-chain aggregated views.

Then, project owners can use our auth service to access the public information for airdrop, credit lending, and other scenarios.

Challenges we ran into

Storing data on-chain can be costly, and we want to handle ownership of data back to the users without affecting the users’ experience, so we designed the off-chain-computing and on-chain validating model based on zk-SNARK. This is a big technical challenge.

Accomplishments that we're proud of

We finish the three modules, architecture design and technical solution tradeoff, PoC of DID Network Profile, Poc of on-chain data analysis and visualization. We also have got the NEAR Protocol and moledao grant.

What we learned

It is difficult to fully exploit the value of the on-chain data with an isolated identity. We should try to build connections between projects and users, and between users and users, in order to exploit more value.
