IDHub will help identity authentication demanders complete the entire process from identity attribute issuance, verification verification and authentication incentives. While realizing the closed loop of IDHUB circulation, it will fully enhance the intrinsic value of the IDHub ecosystem and ensure that all parties in the identity authentication process have the power to drive the system to operate independently.

Project Vision

IDHub is a decentralized digital identity application platform based on open principles and is based on blockchain technology, with good technical compatibility and functional expansion. As an entrance to the digital society, IDHub uses blockchain technology to reasonably verify the validity, authenticity and uniqueness of personal identities, and strives to reclaim identity control rights back to individuals by third-party information service agencies, shape a complete and trustworthy independent identity for users, build a user-led digital identity management and application platform, as well as a secure, autonomous and trustworthy identity management mechanism, and ultimately realize the vision of linking everything with digital identity (social services, digital assets, digital life, etc.).

Project Highlights

Replace the traditional account system, separate accounts and applications, users independently manage digital assets, and conveniently cash out digital assets or replace service providers.

Build a trusted ecological system for the digital economy. Revitalize the existing data of authoritative institutions, endorse personal data assets, and achieve the prosperity of the digital economy.

Provide data fuel for artificial intelligence and create the foundation for digital immortality. Place the data in the user's personal data center to create a digital version of the corresponding body for each person.

Project Technology

Identities based on smart contracts can be verified from individuals or institutions, and can also control digital currency or tokenized assets.

The Merkle tree is a tree where each leaf node is marked with a data block, and each non-leaf node is marked with an encrypted hash algorithm marked by its child nodes. It achieves minimum disclosure of information by providing appropriate hashing, thereby only revealing the required data. This can help the identity system maintain privacy and mitigate the potential side effects of information disclosure.

OpenPDS allows users to store personal data, while all applications or services other than users can only obtain limited or required portions of data. OpenPDS provides a win-win solution for user privacy and user experience, and can play the role of Oracle in digital identity application scenarios. Oracle is a trusted node that automatically obtains data on the blockchain.

Kademlia is a point-to-point distributed hash table that records the results (XOR) of different hash values. Since it is a new metric topology based on XOR operation, Kademlia has reliable stability and performance, and has advantages and features such as delay minimization routing, delay-free fault recovery, and symmetric one-way topology.

The validity of the identity attribute is guaranteed by authentication implemented by JSON Web Token (JWT). JWT is an open standard (RFC 7519) that defines a compact and independent way to safely deliver information in the form of JSON objects between parties. This information can be verified and credited by digital signatures, and the signature is used to verify the issuer of the JWT, ensuring that the message remains intact during transmission.

Identity graph is a representation of behavior between identities. In the graph, nodes are identity, and boundaries are behavior. Behaviors include adding, acknowledging, commenting and trading as friends. On blockchain, we turn these behaviors into transactions. The declaration and proof of identity in the IDHub system are stored in the Merkle tree, and the interaction with other identities is stored in the form of an identity graph.
