Redux Framework Technology

2) Design & Thoughts on Crosschain Logic with Ethereum

• One of the difficulties in cross-chain design is how to confirm the identity of the miners in Ethereum, and the syncronization of the identity of the sub-chain miners. The preliminary design idea is that the identity of the sub-chain miner needs to be updated in the case of the main chain confirmation, that is, the modification of the identity of the sub-chain miner needs to be synchronized with the main chain;
• When a users makes a withdraw request from the sub-chain, the mainchain must be able to verify the authenticity and validity of the request. In order to reduce the amount of data between the main chain and the sub-chain, the data to be verified is organized in the “Merkle” tree structure, and only the root of Merkle needs to be submitted to the main chain.
