We’re thrilled to announce our technical partnership with ARPA.

ARPA is a blockchain-based layer 2 solution for privacy-preserving computation, enabled by cryptographic Multi-Party Computation (“MPC”) which is secure, compatible and scalable.

What is MPC?

Multi-party computation (MPC or SMPC) is a cryptographic protocol that distributes a computation process across multiple parties, where no single party can view the data of others. In other words, MPC allows the joint analysis of data without sharing them.

The synergy of DID and MPC

ARPA’s MPC protocol creates ways for multiple entities to collaboratively analyze data and extract data synergies while keeping each party’s data input private and secure. …

We are proud to announce our partnership with Polkadot Wasm smart contract solution provider Patract.

Under this partnership, Litentry will develop Litentry’s ink! smart contract based on Patract’s Redspot tool, allowing DApp developers to easily integrate cross-chain identities and data on Litentry, identity calculations in different scenarios according to their own algorithm logic, and customize their own user reputation and grading system.

In addition, Litentry expands the contract running sandbox environment Europa provided by Patract, increases the accessibility of Litentry Pallet data, and can directly simulate the interaction with Litentry nodes.

Bondly Finance now integrates with Litentry’s upcoming Crypto Identity & Social Network product called “My Crypto Profile” that allows users to link and verify their Ethereum accounts with Twitter accounts in an automatic and transparent way. This is powered by Litentry Registrar which is an open-sourced software that focuses on automatic verifications, leveraging well-designed cryptographical challenges to further reduce human interventions.

A parachain slot is a scarce resource on Polkadot and only a limited number will be available. For a parachain to be added to Polkadot it must inhabit one of the available parachain slots. Litentry has been developing its parachain for Polkadot and preparing for the parachain slot auction.

With the upgrade of Polkadot’s parachain testnet Rococo, Litentry is now actively conducting auction and crowdloan tests on its test-parachain Litentry Rostock. We can see an overview of the test parachain bids and crowdloan campaigns in the Polkadot.js web application.
