HashKey DID: Decentralized Identifier
HashKey DID is a multi-chain decentralized identity data aggregator, based on smart contracts, NFTs, and privacy computing decentralized protocols, to provide digital identity services for Web3 users.
As we all know, Web 1.0, Web 2.0, and Web 3.0 are the three iterations of the internet.
In the physical world, we have our own ID cards. A large amount of data and social relations are derived based on ID cards. For example, the bank issues a credit card to the customer based on the customer's ID card, determines the credit card limit, and so on. This identity system is controlled by the centralized government.
In Web2, we also have our own identities, such as Google and Facebook accounts. All our online activities can be linked through these accounts basically. The identity system is controlled by the centralized application, which can disable the account at any time without the user's consent, and there is a risk of data leak.
The blockchain-based DID is the Web3 decentralized identity system, which can record the user's on-chain behavior data. Based on these data with the algorithm, the user's on-chain credit level or score can be calculated. Since the on-chain data cannot be tampered with, the user's on-chain data is trustworthy.
In summary, DID is not only the core element of Web3, but also the infrastructure of Web3, and the foundation of various DApps, governance and incentives in the Web3 era.
HashKey DID Technical Architecture:
Decentralized Wallet + Smart Contract + Decentralized Storage + Privacy Computation = HashKey DID
HashKey DID currently supports imToken, MetaMask, Kaikas, Coinbase, Crypto.com, ATON, and other crypto wallets as the front-end entry;
HashKey DID has deployed smart contracts on many networks such as Ethereum, Klaytn and PlatON, and will further expand to Polygon, Polkadot, Aptos, zkSync and other networks;
HashKey DID adopts decentralized storage methods such as IPFS and Arweave. Combined with PlatON privacy computing technology, it is a completely decentralized multi-chain digital identity system.
HashKey DID Product Structure:
HashKey DID is the infrastructure of Web3, aiming to provide easy-to-use Web3 solutions and tools for Web3 users, developers and projects. The core elements of HashKey DID are: non-transferable NFT + multi-signature smart contract.
.key DID supports users to register, verify, authorize, and sign on Web3, and has begun to provide KYC verification services to users in some countries and regions to help users perform real-name authentication. HashKey DID does not store any users’ private information.
Credential is essentially an open, flexible and user-friendly medal NFT. The credential function will help Web3 projects better understand user needs, serve existing users more efficiently, and attract potential users.
Islands, based on HashKey DID Credential, is established to serve DAO organizations.
Space is the personal dashboard of Web3 users and the starting point for users to socialize with Web3. Users can show their Web3 achievements here, including collected NFTs, OST and SBT, social relations, and other on-chain assets and behaviors.
Credit Score is a digital credit rating system created by HashKey DID, which generates credit reports for users based on the user's identity data through the credit model.
As a Web3 infrastructure, HashKey DID is building HashKey DID DAO, gathering people with the common goal to improve Web3 DID together.
