Merkle trees, also known as binary hash trees, are data structures used in blockchain technology to ensure the integrity of data and enable efficient verification. Each leaf node represents a transaction, and every parent node is the hash of its child nodes. This structure allows for quick identification of any changes in transactions and the ability to verify the entire branch's validity using only the root hash (Merkle root). Merkle trees are crucial for maintaining security and preventing tampering in blockchain networks.
