What is a Merkle Tree?
The Merkle tree is a data structure that is used in the blockchain to verify the integrity of data. It is a tree structure, where each node contains the hash value of its child node. The root node of the tree contains the hash - the value of all data in the block. How does the Merkle tree work on the blockchain? Imagine that we have a block with data about several transactions. We can create a tree where each transaction will be represented as a leaf, and their hashes will be nodes at higher
