Band Protocol is a cross-chain oracle platform that aggregates and connects real-world data and APIs to smart contracts across multiple blockchain networks. Built on the Cosmos SDK with its own BandChain, the protocol enables decentralized data feeds for price information, sports results, weather data, and any other external information needed by dApps. Band Protocol uses a delegated proof-of-stake consensus with validators who serve as data sources, ensuring reliable and tamper-proof data delivery. The oracle supports multiple blockchains including Cosmos chains, EVM networks, and others, competing with Chainlink as a cross-chain data infrastructure provider.
