Due to the structural characteristics of the Merkle tree, when the data in the leaf nodes changes, its hash value will also change, thereby affecting the hash values  of the intermediate nodes and the root node. By comparing the root hash values before and after modification, we can determine whether the data has been tampered with."}]}],"pr":"7d56424d66948f326f806317a76ef83d280ff976eb7280644b03b8bbf453817e"}
