ARPA Network (ARPA) functions as a decentralized framework for secure computations, aimed at enhancing the fairness, security, and privacy of blockchain technologies. Its distinctive threshold BLS signature network forms the backbone for various applications, including a verifiable Random Number Generator (RNG), secure wallets, cross-chain bridges, and decentralized custody solutions across numerous blockchain platforms.
Originally branded as ARPA Chain, this privacy-focused Multi-party Computation (MPC) network was established in 2018. Over the years, the ARPA Mainnet has successfully executed more than 224,000 computation tasks, showcasing its capabilities. The team's extensive background in MPC and cryptographic methods has been instrumental in developing their innovative threshold BLS signature schemes (TSS-BLS), paving the way for the current ARPA Network.
One of the standout applications utilizing ARPA's infrastructure is Randcast, a verifiable Random Number Generator. Randcast provides a cryptographically secure source of randomness, offering enhanced security features and cost-effectiveness compared to traditional methods. Its tamper-resistant randomness is particularly beneficial for a variety of sectors, including the Metaverse, gaming, lotteries, NFT minting, whitelisting, key generation, and the distribution of tasks for blockchain validators.
