"A Merkle tree is a numerical data structure composed of blocks of data within a blockchain. Its function is to provide a summary of the transactions within the blockchain by creating a digital fingerprint of each transaction. The benefit of using a Merkle tree is that it provides sufficient verification of the content without having to display every single transaction within the blockchain. The Merkle tree, also known as a hash tree, is heavily used by Bitcoin and Ethereum."
