In computer science, a TREE is a data structure representing a hierarchical structure consisting of interconnected nodes.

Each node can have one or more children but only one parent, with the root being the exception as it has no parents.
Here's an example: pic.twitter.com/Gr1E4sdiVr -
In a Merkle tree, data is organized into a hierarchy of nodes, each representing the hash of its child nodes.

This creates a tree-like structure where the root node represents the hash of all the data in the tree. pic.twitter.com/j9NScOeIlz -
The use of Merkle trees in blockchain technology provides several benefits,

including:
- faster verification of transactions
- improved security
- efficient storage of large amounts of data. -
Some examples of uses for Merkle Trees include NoSQL systems, Bitcoin and Ethereum networks, and hash-based cryptography.

Interesting fact:
Merkle trees are also used in version control systems, such as Git, where they are used to efficiently track changes in files and dirs -
For Blockchains:

Valid transactions are grouped in batches and stored in blocks in a blockchain.
These transactions are hashed and encoded into a Merkle tree structure to ensure secure and efficient encoding of the blockchain data. -
Merkle trees are an effective cryptographic commitment scheme that works as follows:
— Francesco (@FrancescoCiull4) April 8, 2023
- The root of the tree represents a commitment.
- The leaf nodes can be revealed and verified to be included in the original commitment. -
From NoSQL systems to blockchain networks and beyond, Merkle trees have proven to be a versatile and secure way to encode data hierarchically.

Whether you're into crypto or distributed systems, Merkle trees are worth exploring. -
That's it for our discussion on Merkle Trees.
