Validators on the BandChain blockchain place information requests via APIs or different net sources. Subsequently, the validators relay the info to entities and customers. The protocol may ship information to totally different blockchain networks on the premise of Inter-Blockchain Communication or IBC protocol of Cosmos.
The most vital spotlight of the Band Protocol blockchain oracle defined intimately would deal with flexibility for creating customized oracle scripts. Users may create customized oracle scripts for receiving information streams from a number of exterior sources in the true world. Band Protocol leverages the Delegated Proof of Stake or DPoS consensus mechanism. Therefore, validators need to stake the native token, i.e., BAND, for retrieving information and voting on the authenticity of the info.
3. Decentralized Information Asset
The subsequent addition to the record of high blockchain oracles would level at Decentralized Information Asset or DIA. It is an open-source oracle platform tailor-made particularly for the DeFi panorama. DIA makes use of crypto-economic incentives for offering, sharing, and utilizing clear worth information verified by a number of contributors. The customizable information feeds assist customers in creating particular feeds via the configuration of methodologies and sources based on their wants.
Users can entry the providers of DIA oracle with none prices. The verification of worth information for monetary and digital property via a group of stakeholders provides the peace of mind of information authenticity. On high of it, the scalability benefits of DIA be sure that it might probably preserve tempo with the dynamics of the DeFi panorama. DIA provides oracle providers for a number of blockchains, akin to Ethereum, Fantom, Solana, Avalanche, Polygon, and Arbitrum.
