overview

Why do blockchains
need oracles?

Blockchains are great at providing immutable storage and deterministic verifiable computations. However, they cannot access trusted real-world information available outside their networks. Band Protocol enhances smart contract functionalities by granting access to reliable data without any central authority or points of failure.

Bring more use-cases to
blockchains beyond DeFi

Band Protocol's flexible oracle design allows developers to use any data including real-world events, sports, weather, random numbers and more. Developers can create custom-made oracles using WebAssembly to connect smart contracts with traditional web APIs within minutes.

BandChain

Based on Cosmos' state-of-the-art SDK, BandChain allows efficient, flexible, and scalable data query secured through cryptographic proofs.

Band Token

BandChain utilizes the native BAND token to secure the decentralized oracle network through delegated Proof-of-Stake and settlement for transaction fees. Validators are required to stake BAND token to fulfil data requests in return for a portion of the query fees and earn block rewards.
