How to build the bridge between two different consensus blockchain platform?

use case:

1.we need to ensure visibility of the transaction in both platforms to assure its integrity

  1. When a smart contract is established on one platform, that contract can be referred to, transacted and transferred to the other platform easily and securely

  2. The bridge should be able to leverage the one platform and other platforms depending upon the transaction type and the TPS requirement. If it requires a faster TPS, then one consensus framework or else normal mining framework of another consensus

  • there are multiple ways of securing a cross-chain transaction, but I'm not sure what you are talking about for point 2, do you mean that you want cross-chain contract calls? so a contract on chain A can call a contract on chain B and get the return result? Or by "transferred to" do you mean you want the contract on chain A itself being able to be transferred to chain B?

  • @hellpeach yes, want the contract on chain A itself being able to be transferred to chain B
