Overview. Merkle trees are typically implemented as binary trees, as shown in the following image. However, a Merkle tree can be created as an n n n-nary tree, with n n n children per node. ... Then each pair of nodes are recursively hashed until we reach the root node, which is a hash of all nodes below it.

Is blockchain a binary tree?

A Merkle tree is a data structure that is used in computer science applications. In bitcoin and other cryptocurrencies​, Merkle trees serve to encode blockchain data more efficiently and securely. They are also referred to as "binary hash trees."

What is a binary hash tree?

A Merkle tree is a non-linear, binary, hash tree-like data structure. Each leaf node of the tree stores the hash value of a data element, while a middle node stores the hash of the hashes of it's two corresponding child nodes.
