A hash tree, or Merkle tree, is a data structure used to efficiently verify the integrity and consistency of data in distributed systems by hashing pairs of nodes until a single hash, the root hash, is obtained. This structure allows for secure and efficient verification of large datasets, making it a fundamental component in blockchain technology and distributed file systems.

A Merkle Tree is a data structure used in computer science and cryptography to efficiently verify the integrity and consistency of data. It organizes data into a hierarchical tree structure where each non-leaf node is a hash of its child nodes, enabling quick and secure verification of large datasets with minimal data transfer.

Distributed systems consist of multiple interconnected components that communicate and coordinate their actions by passing messages to achieve a common goal. They offer scalability, fault tolerance, and resource sharing, but also introduce challenges such as network latency, data consistency, and system complexity.
