A sidechain refers to a branch chain that exists parallel to the main chain, and asset transfers between the two chains can be achieved through specific cross-chain solutions. The process is as follows: first, lock the assets that need to cross-chain onto one chain (called the parent chain), wait for the assets to be locked, and then unable to be  transferred or opened on the chain. After that, record the locked asset status on the parent chain; at this point, specific operations can be implemented on the sidechain (such as voting decisions, transactions, etc.)."}]}],"pr":"3cfd402c39c4767c95bb81811a12828d05d13cf5f0f97af7e27060919ca2a2f6"}
