Basic in DID

**Basics in DID** What is DID data?**

DID data is information that proves identity ownership in a decentralized system. This data can be directly linked to an identity, such as a driver's license or COVID-19 test result, or it can be associated with an identity following analysis, such as code contributions to a decentralized system or voting activities in a decentralized autonomous organization (DAO).

Indexing these various data types is critical, as it builds a cross-system index of DID data, a vital part of the Web3 network. This provides a robust database, accelerating the application of Web3, and helps establish a Web of Trust, as all data in a decentralized system is verifiable and tamper-proof.

The rise of decentralized applications has increased the demand for DID data. Key sectors include decentralized credit lending, DAOs, and decentralized personalized recommendation systems. However, a lack of ready-made decentralized identity data sources exists in the current network.

One potential solution is to establish a standardized common language for exchanging credentials between different identity systems, like the Presentation Exchange protocol. This helps reduce data friction between systems and enhances consistency, but adoption of such a protocol can be time-consuming.

The DID Aggregator

The DID Aggregator is a model we've developed to solve the issue of scattered digital identities. It's an open, decentralized system that can work with any DID standards. It allows anyone to share their identity-verification algorithms, and provides a one-stop service for indexing, authenticating, and aggregating DID data, ensuring reliability and data integrity.

Open Protocol

Our Aggregator is an open-source protocol where any user can upload DID verification algorithms and generate decentralized credentials through the network. These algorithms are recorded on a blockchain and, if approved by a DAO, are marked as trusted.

Decentralized

To remove any single point of failure in the DID verification system, we've built a Decentralized Validator Network. This network processes verification requests and returns trustworthy credentials, with the process being overseen by a randomly selected set of validators.

Easily-Verifiable

Verification of a credential can be quickly done by verifying the signatures of the validators in the credential document. All recognized validators are registered on a blockchain and governed by a Proof of Stake (PoS) protocol and a community-elected council.

Minimum data on-chain

Only minimal user data is stored on-chain, mainly encrypted DID-account relationships. Other DID data is returned to the service requester in real-time.

Privacy-Preserving

During the verification process, we apply confidential computing methods and ID obfuscation technology to ensure privacy, so validators won't know the true owner of the DID data or where the data is going.

Interoperability

The DID Aggregator is designed to integrate with various identity systems and adopt interoperable standards, making it easy to work with existing tools and software libraries.

Democracy

All functions in the aggregator can be altered by a decentralized autonomous organization (DAO). The community can vote on and implement protocol upgrades, maintaining an environment where users can trust that their credentials are verified.

Conclusion

The DID Aggregator provides an efficient, trustable solution for handling scattered digital identities in a decentralized manner, underpinning the evolution of Web3 networks.
