Assuming after Dokodoa network provides data feed oracle services to the Ethereum and BSC, theoretically, smart contract on Ethereum is able to trigger cross-chain state changes, flowing through Dokodoa client nodes, calling into smart contract on BSC. Thus, Dokodoa network is acting as a connector or bridge between the supported isomorphic or heterogeneous chains. A simple application scenario. For example, looking at the liquidity farming pools on Ethereum, the assets on Ethereum can only be used to farm the liquidity pools on Ethereum, and the same is true for BSC. With Dokodoa, the assets on BSC can be used to farm the liquidity pools on Ethereum, or the assets on Ethereum can farm the liquidity pools on BSC. It thus improves the liquidity of the three chains as well as increase the share of TVL for cross-chain liquidity farming. By deploying Dokodoa oracles and cross-chain bridge smart contracts on Ethereum, BSC, and Polygon, it defines the collaboration functions on those chains, so that the Dokodoa smart contract functions on Ethereum can call the smart contract functions on Polygon or BSC from the Dokodoa cross-chain bridge oracles, and make atomic updates to the status changes of cross-chain orders and account balance. The following shows the application and potential of Dokodoa cross-chain bridge in cross-chain interoperability.
