A sidechain refers to a branch chain that exists parallel to the main chain, and the two chains can transfer assets between each other through specific cross-chain solutions. The specific process includes locking the assets that need to be cross-chained onto one chain (called the parent chain), waiting for  the assets to be locked, and then unable to be transferred on the chain and open to the outside. Subsequently, the locked asset status is recorded on the parent chain, and then specific operations are implemented on the sidechain (such as voting decisions)."}]}],"pr":"99e3ddca75d6c01094a1ed22b835af95287ea00eb557aad8f06726e66dbe6dba"}
