Rain (RAIN) is a decentralized, AI-powered weather prediction and climate data platform built on the Solana blockchain, enabling users to earn rewards by contributing weather data and staking tokens. Unlike traditional weather services that rely on centralized data sources, Rain leverages a global network of IoT devices, satellites, and community contributions to create hyperlocal, real-time weather forecasts. In 2025, as climate volatility increases and demand for decentralized physical infrastructure networks (DePIN) grows, Rain positions itself as a critical tool for agriculture, logistics, and disaster preparedness.
