ARPA Network's random number generator (RNG) Randcast has been launched on the L2 chain Base created by Coinbase. The team stated: "After recently integrating with Optimism, Randcast is expanding its coverage by adding new features. To ensure reliable randomness, Randcast uses multiple nodes in the ARPA network to generate randomness through BLS threshold signature tasks, which means that no single node has the ability to manipulate the final randomness result."
