Asset transfer between the two chains can be realized through specific cross-chain solutions. The specific  process is as follows: first, the assets that need to be crossed to another chain are locked onto the main chain. After the assets are locked, they cannot be transferred on the main chain and are exposed to external threats. Then, specific operations can be carried out on the sidechain (such as voting decisions, transactions, etc.), and all operations on the sidechain are independent and do not affect the parent chain."}]}],"pr":"415996a48220293b70493b542da915001217adecfd8d6cfe1967e448e474f3d3"}
