Introducing Litentry

2 min readSep 14, 2020


Litentry network features identity layer on Polkadot ecosystem.

Litentry enables user to aggregate identities from other chains, features an identity matching and identity staking mechanism, as a whole it consists of decentralized identity and user activity data aggregation infrastructure.

With an aggregated cross-chain identity, blockchain projects could offer dedicated graded services/functions according to the identity’s quantified data. For example, if a new project knows that an account is a Polkadot validator, and it spends hundreds of DOTs on another Parachain for half a year, then the project could directly gift this specific user some token to start to play with, or send him/her an attractive offer of the new DeFi product, or accredit him to be a validated voter.

Identity Matching is a blind matching-making with random anonymous identities picked from on-chain identities pool, and candidate identity data is processed by the substrate off-chain worker. The network sends the matchwinner’s DID as a matching opportunity back to the matching buyer. The buyer does not have access to other identities in the identities pool but only the matchwinner’s DID, thus match buyer pays the LIT token(Native Token on Litentry Network) in exchange for a matching opportunity.

Identity Staking is the process that an identity owner sends the snapshot of their identity document and DID to the identities pool of blockchain, and authorize the read permissions to the validator node, thus getting staking and matching rewards in the following blocks. The identity document is encrypted and saved in a decentralized database like IPFS or on-chain key-value store, and DID is stored on chain.

With identity staking and identity matching, we construct the basic economic model of the identity-based network without selling user data. Not only identity stakers and matching buyers benefit from the matching market, but the DApps connected to Litentry also get match fees as identity contributors. In this way, Litentry encourages more attendee into the future of Web3.

For more information on Identity Staking and Identity Matching, please read our lite paper.

Litentry has a technology-driven team in Germany, the Founder and an early contributor are from Parity, it has a strong engineering team with Ethereum project background.

With the grant from Web3 Foundation in 2019, the Litentry team has built the following products for a user-centric ecosystem.

  1. Litentry Network: runtime built with Substrate
  2. Litentry Authenticator: a mobile identity management hub
  3. Litentry DApp Playground: a collection of DApp samples
  4. Litentry Data Center: an identity-based IPFS explorer
  5. Litentry Graphql Caching Server: speedup IPFS connection
  6. Litentry SDK: tools for frontend developers
