Arpa Chain

About Arpa Chain

ARPA Network (ARPA) is a decentralized secure computation network designed to enhance privacy, security, and fairness across blockchain systems. Built on a threshold BLS signature scheme, ARPA provides infrastructure for verifiable random number generation, secure wallets, cross-chain bridges, and decentralized custody. Originally founded in 2018 as ARPA Chain, the project evolved from Multi-party Computation research into its current cryptographic framework. Randcast, its flagship application, delivers tamper-proof randomness suited for gaming, NFT minting, lotteries, and validator task distribution, making ARPA a foundational layer for blockchain applications requiring trustless and verifiable computational outputs.
