A hash tree, also known as a Merkle tree, is a tree structure where each leaf node is labeled with the cryptographic hash of a data block, and each non-leaf node is labeled with the cryptographic hash of its child nodes. This allows for efficient and secure verification of large data structures. The concept was named after Ralph Merkle, who patented it in 1979.
