Band Protocol, launched in 2019, is a cross-chain data oracle platform that aggregates and connects real-world data and APIs to smart contracts. It enables blockchain applications such as DeFi, prediction markets, and games to be built on-chain without relying on the single point of failure of centralised oracles. Originally constructed on Ethereum, Band Protocol is blockchain-agnostic, with plans to support major blockchain environments. Band's dataset tokens incentivise data providers and ensure data integrity, aligning economic incentives with reliable data provision. As an open standard for data governance, Band envisions being the decentralised world's database for secure and trustless data access.
