Merkle tree usage has been found in the computer science industry. It is a type of database used to store and encode some sort of information. In the crypto industry, a Merkle tree helps in protecting and encrypting the blockchain data of any cryptocurrency more effectively. “Binary Hash Tree” is yet another term given to this. In blockchain technology, we can consider it as one of the fundamental aspects. It is made up of hashes of different blocks with data. The data that is there inside a block, for that, works as a summary that works in a mathematical data structure. Where large data are lying for verification, it helps it to be done quickly. Along with this it also helps in verifying the data consistency as well as the content. BTC and ETH both utilize the Merkle tree for their blockchain.
The patent to its invention is given to Ralph Merkle who invented the idea in 1979. It is a type of data structure where there are nodes, the one is the leaf node and the other non-leaf node. The leaf node is classified as the hash of the data block and the latter as the hash of the child nodes. The lowest node of the tree is the leaf node.

How A Merkle Tree Carries Out Its Work?
A Merkle tree is a kind of record keeping tree that records all the transactions inside a block. This is executed with the use of a fingerprint. It helps a user to decide whether a specific type of data can be added to a block. This tree is created by some hashing groups that are continuously calculating till there is only one single hash remaining. The hash is then named as either root hash or as the Merkle root. The approach followed for the Merkle tree is bottom-up.
Each leaf node carries some sort of transactional data and the other nodes which are non-leaf are hash prescribing the previous hashes. Since this tree is binary, the leaf nodes are also required in even numbers. But if it is odd then to make it even the last hash is copied.
Its Benefits In A Blockchain?
- It provides benefits in giving your data integrity as well as authenticity by validating it.
- As compared to other databases, the disk space occupied by a Merkle tree is much less.
- For verification purposes, the data in a Merkle tree can be broken into smaller parts so that verification is carried out with ease.
- The verification of the data is much quicker when done with the help of a Merkle tree.
Why Is It Important For A Blockchain?
Without the help of the Merkle tree, every single node would have to keep the transactional data in form of duplicates with them, which would be so inconvenient too.
For data transfer, any authentication request would require the transfer of the data in large amounts through the network. The data so transferred first will need validation that will have to be validated by the nodes themselves.
To ensure the non-existence of modification to compare ledger, the device that will be used for validation will require a lot of computational power.
Closing thought
The information in the blog is about the Merkle tree, which is widely used in the blockchain sector. The definition of a Merkle tree is given, including its mode of operation. Furthermore, the article discusses why it is crucial in the blockchain sector and some of its fundamental features. It is a sort of extra security provided to a blockchain network.
