About Rain
Rain is a decentralized prediction markets protocol on the Arbitrum One blockchain. It provides on-chain infrastructure for creating, trading, and resolving permissionless markets on real-world events, including elections, sports outcomes, and financial results. The protocol is built as infrastructure rather than a single application. Individuals, communities, organizations, and AI systems can create both public and invitation-only prediction markets through it. Rain settles on Arbitrum One and inherits its Ethereum-derived proof-of-stake security. Markets are resolved using a combination of AI oracles and decentralized human arbitration. The native token, RAIN, is an ERC-20 token used for governance through a decentralized autonomous organization and for paying fees within the prediction market system. The protocol applies a deflationary buy-and-burn mechanism: a portion of trading volume, commonly cited at 2.5 percent, is used to purchase and burn RAIN tokens. The maximum supply is fixed at approximately 1.14 to 1.15 trillion RAIN, with a circulating supply of over 700 billion. The burn mechanism reduces total supply over time.
