A Merkle Tree contributes to blockchain security by providing an efficient way to verify the integrity of data stored in blocks within the blockchain. Each block in a blockchain contains a cryptographic hash of its data, and these hashes are used to build a Merkle Tree structure. By hashing pairs of data and then hashing the results until a single root hash is obtained, a Merkle Tree allows for quick verification of the entire dataset. This means that any tampering with the data stored in any block can be easily detected by checking the hashes in the Merkle Tree. As a result, a Merkle Tree helps ensure the immutability and integrity of the blockchain, enhancing its security.
