ARPA Network is a decentralized computation layer focused on privacy-preserving technologies, most notably secure multi-party computation (MPC) and threshold BLS signatures. Originally launched in 2018, ARPA has evolved into an infrastructure provider that enables confidential, verifiable operations on-chain without exposing raw data. Its design allows multiple parties to jointly compute data without revealing their individual inputs—opening doors for trustless collaboration across blockchains.
ARPA is pioneering Verifiable AI by integrating zero-knowledge machine learning (ZKML) to ensure AI models are both private and provably accurate. This approach enables the generation of cryptographic proofs that AI computations were executed correctly without revealing sensitive data. ARPA's initiatives aim to bring transparency and trust to AI applications across various industries.
At the heart of ARPA’s current utility is Randcast, a verifiable random number generator (RNG) that delivers tamper-proof randomness for smart contracts and decentralized applications. Built on ARPA’s threshold cryptography, Randcast serves gaming, NFTs, lotteries, and governance tools that demand fairness and unpredictability. Unlike traditional oracles, Randcast prioritizes decentralization, auditability, and multi-chain compatibility.
