ARPA is a blockchain-based layer 2 solution for privacy-preserving computation, enabled by Multi-Party Computation (“MPC”). Founded in April 2018, the goal of ARPA is to separate data utility from ownership and enable data renting. 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.

Developers can build privacy-preserving dApps on blockchains compatible with ARPA. Some immediate use cases include credit anti-fraud, secure data wallet, precision marketing, joint AI model training, and key management systems. For example, banks using the ARPA network can share their credit blacklist with each other for risk management purposes without exposing their customer data or privacy.

ARPA partners with organizations and tech companies like IEEE Standard Association, ISO, JD.com, Sinochem Group, CAICT, Elrond, and Chainlink.
