In blockchain  technology, Merkle Tree is employed to ensure that data cannot be tampered with. The leaf nodes contain the hash values of the data blocks, while the non-leaf nodes contain the hash of their descendant nodes' hash values. When verifying whether a certain piece of data exists in the Merkle Tree, it can be quickly confirmed by efficiently searching for its hash value."}]}],"pr":"f2803230016d188d7c6452b0657d18f4450d43feaefcd6abe72397e80b271527"}
