In cryptography and computer science, a hash tree or Merkle tree is a tree in which every "leaf" (node) is labelled with the cryptographic hash of a data block, and every node that is not a leaf (called a branch, inner node, or inode) is labelled with the cryptographic hash of the labels of its child nodes. A hash tree allows efficient and secure verification of the contents of a large data structure. A has…

WebJan 23, 2024 · The general technique for tree hashing (independently of the issue of partially revealing content) is to define the hash of nodes as the hash of the concatenation of the hash of their leaves, with a suffix (or prefix) that makes the input of the hash different for leaves and nodes.
