A Merkle tree is a data structure used in cryptography and computer science that provides efficient and secure verification of large-scale data.
Assume that there is a list of data with n elements, a Merkle tree constructed on this list consists of log n layers. The leaf nodes consist of the hashes of data and upper nodes (inner nodes) consist the hash of the concatenation of their children's hashes.
Root node of a Merkle tree allows verification of the data.
The path of a leaf node includes the hash values of the inner nodes that generate the hash of the root of the tree with the hash of that leaf node.
This is an implementation of a Merkle tree written in python.
- mtree.py is a python file that contains the class node and class tree including the Merkle tree functions.
- At the end of the file there is a test script.
- This module can be imported in SageMath scripts as well.
