Litentry is a Substrate - based decentralized cross-chain identity aggregation protocol.

Litentry will provide refined on-chain identity credit services for DeFi, on-chain governance and other applications inside and outside the Polkadot ecosystem. Together, Litentry will build a trusted decentralized identity aggregator in the blockchain network, become an important infrastructure in the Web 3.0 network, and be ready for large-scale application implementation.

The realization of decentralized identity system will replace the account system of Web2.0 and become an important part of Web3.0. By integrating the information of different online identities on the chain, including DeFi and data generated by on-chain governance, an on-chain identity credit system can be created, helping to solve the problems such as low efficiency of airdrop, lack of credit lending and PoS power concentration in most blockchains. At the same time, users do not need to log in accounts repeatedly when browsing and using different applications, but use the same identity to log in to different platforms.

Litentry is a decentralized identity aggregator featuring Substrate built blockchains and distributed decentralized identity (DID) authentication networks. The DID authentication network can provide a decentralized, verifiable identity aggregation service for any DID application on the blockchain, enabling dApps to retrieve DID data belonging to the same identity controller in real time from multiple service endpoints in a trusted manner. Litentry's identity aggregator takes on the redundant processing, code, and other challenges involved in understanding the unknowable DID mechanism, and acts as the underlying driver protocol for decentralized credit computing and identity generation in Web 3.0 networks.

Litentry is a cross-chain identity aggregator in the Polkadot ecosystem, consisting of an identity-based network and associated tool applications, such as mobile clients. Litentry's main features are "Identity Linking" -- Linking identities across different blockchains -- and Credit Computation, which means users can pull historical data or transaction data from different blockchains, An aggregate reputation is then calculated using the Litentry blockchain. On Litentry, any user or application can participate in the modification of all algorithms in the process of credit calculation on the blockchain. Users can modify computing methods and identity data sources by voting. At the same time, Offchain Worker can also get a real-time credit value, which can be applied to authorization scenarios. Or management on the chain. The key design principles in Litentry are transparency, no trust, and voluntary participation. Transparency means that all data and functions are exposed in the blockchain, such as the Service Endpoint from which the data source is collected, which is completely different from the credibility calculated by the banking system. In addition, Litentry is permissionless, and anyone can participate in the network as an authentication node. At the same time, Litentry participates autonomously. Just like Kusuma and Polkadot networks, users can modify Litentry algorithms through DAO. Basically, it's like an identity predictor. Litentry fully follows the W3C's DID (decentralized Identity) specification. First, Litentry does not store users' identity data, which is stored in decentralized storage networks. Litentry connects them together. The second is the decentralization of identity data authorization, identity relations and data distribution through the Litentry authentication node in the chain of workers.

LIT Token is a native Token of Litentry network, and its use value comes from Litentry credit calculation. Whether users or applications need this real-time credit data, they will have to pay a certain LIT fee as a Gas fee to integrate identity data and generate credit.

Identity Staking of Litentry networks. For example, if a user is a long-term liquidity providers, he can in Litentry choose the label "long-term liquidity providers", and send a request to block chain to prove you are qualified for this label, after validation of network node receives the request from chain work under the machine to the corresponding block chain to obtain these data and verification, If the result is correct, the information is uploaded to the "Identity Pool" of the Litentry blockchain, where it waits for a match. The process of waiting for a match is that the buyer of a match chance will send his demand to the blockchain. The blockchain will randomly select some identities in the identity pool through the random number mechanism, and then select the winner of the match and return it to the buyer of the match chance. Litentry App will allow users to use their integrated DID identity to interact with blockchain, participate in DeFi, governance, etc. Its main functions are identity integration, governance incentives, wallet associations, and finance-related services. For example, the Litentry App will integrate Polkadot Registrar functionality, cross-chain information exchange functionality, native Litentry Runtime support, on-chain governance support, and boca Light client support.

The Litentry network incentivizes users to link their identities to the Litentry network. In return, users who search and match users through the Litentry network pay for the service.

Litentry focuses on providing decentralized, generic identity aggregation services for DID users and DID applications, addressing the technical challenges posed by the unknown DID mechanism in Web 3. Litentry products provide users with an identity data management platform and provide blockchain applications with identity owner credit data in real time.

Litentry is a cross-chain identity aggregator in the Polkadot ecosystem. Its main function is "identity connection" and credit calculation. Users can extract their historical data or transaction data from different blockchains and calculate a comprehensive reputation through Litentry blockchain to generate a comprehensive identity. The goal is to create a decentralized identity framework for the future Web3.0 network, which will play a role in on-chain governance, mortgage lending, credit transactions and other scenarios. The team has developed hardware wallet and DAO products, and has been supported by WEB3 Foundation since 2019. In October 2020, the team completed the private financing of 1.46 million DOLLARS, which was obtained by opening new coin mining in Binan on January 29, 2021. February 4, 2021 binance officially listed Litentry (LIT).
