Introduction
Ever wondered how a giant online ledger can grow with new transactions constantly.
Can guarantee everyone that the information is accurate and hasn't been tampered with? Merkle Tree is a secret weapon of blockchains, as this ingenious data structure works as a magical fingerprint that ensures the integrity of information in a way that’s both efficient and secure.
In this blog, you will learn what is merkle tree and root, how it works, and how they keep the blockchain honest!
Understanding The Concept of Merkle Tree
Blockchain is a peer-to-peer network consisting of blocks linked together. A hash tree, or Merkle tree helps blockchain to encode data efficiently and securely. It enables quick verification and data movement. When a transaction happens on the blockchain it create a hash, which is stored in a tree-like structure, linked to its parent.
The parent is a merkle root which is the last transaction hash. It connects all transaction hashes in a block, creating an upside-down binary tree. The hashing starts at the lowest level nodes and continues at higher levels until reaching the single top root hash, the Merkle root.
This root hash contains all information about every transaction hash on the block, offering a single-point hash value that enables validating everything present on that block. The Merkle tree and Merkle root mechanism significantly reduce the levels of hashing required, enabling faster verification and transactions.
How Merkle Tree Works?
Cryptographic hash functions are efficient and irreversible one-way functions used in cryptography. They are commonly used in Message Direct (MD), Secure Hash Function (SHF), and RIPE Message Direct (RIPEMD) families.
Now, take an example, if you use the SHA256 hash algorithm, you will get the following output

In Merkle trees all transactions comes in a block and generate a digital fingerprint of operations, are built from the bottom using Transaction IDs. Each non-leaf node is a hash of its previous hash, while every leaf node is a hash of transactional data.
A simple example of a Merkle Tree in Blockchain is a scenario where four transactions are hashed, resulting in two hashes: Hash ABCD. The Merkle Root is formed by combining these two hashes, forming a unique hash tree.
Merkle Hash Tree Architecture Functions
Merkle hash tree functions are cryptographic algorithms that convert random data into fixed-size outputs. They are known for their irreversibility and are used in cryptography. The Merkle Tree function creates a digital fingerprint of operations by adding all transactions in a block. When only one hash of the Merkle Root (or Root Hash) is left after repeatedly hashing pairs of nodes, the Merkle Tree is created. This technique ensures the security, integrity, and integrity of data blocks transferred through a peer-to-peer network.
The Merkle Root guarantees the security, integrity of data blocks transferred through a peer-to-peer network. Although more complex than a simple Merkle Tree, the illustration explains how these algorithms operate and their success.
Merkle Tree in Blockchain: Benefits
Let's now examine the advantages of Merkle Tree in blockchain technology:
It helps wth verifying data accuracy and provides data's integrity. The ability of Merkle Tree to compress a lot of data into a single Merkle root is one of its main advantages in the blockchain.
Blockchain merkle trees simplify the process of data verification by allowing nodes within a network to confirm individual transactions without having to download and validate the complete blockchain.
One important advantage of Merkle trees in blockchain is the security of traceability and transparency. The data format is efficient, ensuring data accuracy takes only a few seconds.
It promotes accountability and trust by improving the network's overall data visibility.
Merkle trees minimize the amount of data transferred between nodes, which is a critical factor in lowering bandwidth requirements.
Use Cases & Examples of Merkle Tree
Merkle trees are used in various blockchain applications like;
- Amazon DynamoDB
- Apache Cassandra for data replication
- Git for managing global projects
- Interplanetary File System (IPFS) for storing and sharing files across a distributed network.
These distributed databases control discrepancies, while IPFS leverages Merkle trees for efficiency and security in data management. Merkle hash trees are a cryptographic process that transforms arbitrary data into a fixed-size output, with a unique characteristic of irreversibility. They are one-way cryptographic methods designed to operate in a singular direction, with notable hash families like SHA-2 and SHA-3. This approach marks a significant shift from conventional centralized file storage.
Why Merkle Tree is Important for Blockchain?
Merkle trees are a part of bitcoin. They help separate the data from its evidence by hashing accounting records. Without them, nodes would have to keep transaction copies, which would be unimaginable. To confirm a previous transaction, nodes would need to connect to the network and compare each entry line by line, which could compromise the network's security. Additionally, every verification request for Bitcoin requires sending large packets over the network, which would require significant processing power to compare the ledgers. Merkle trees can demonstrate that a transaction can be legitimate with minimal information sent across the network and show that both ledger types use the same nominal computing power and network bandwidth.
That is why, Merkle Trees are essential for blockchain technology. In simple words, to separate the proof of data from the data itself you will need one. Without them, every node on the network would have to maintain a complete copy of every Bitcoin transaction, requiring significant data transfer. This would require a significant amount of computing power to compare ledgers, making it difficult to validate transactions. Merkle Trees, on the other hand, have records in accounting, separating the proof of data from the data itself. This allows for transactions to be valid with only a small amount of information across the network. Additionally, it allows for the comparison of ledger variations in terms of nominal computer power and network bandwidth.
