Data Integrity: Merkle tree connects each layer's data nodes through a hash function, forming a hierarchical structure. Each node contains a  hash value, which is the result of hashing its corresponding data block. When a data block is changed, its hash value also changes, causing the hash values of the connected nodes and higher-level nodes to change as well. Therefore, the entire Merkle tree reflects this change, ensuring data integrity."}]}],"pr":"86952ad5cbe56247170879216b473268c27b5c022f7275e3d12355fbc1e52b7a"}
