Blockchain blocks hold batches of valid transactions, hashed and encoded into a Merkle tree.

what is the purpose of Merkle Tree ?

Merkle trees are used to encode blockchain data more efficiently and securely.

From the below we can define Merkle tree (also called hash tree) as a tree in which leaf nodes are labeled with the cryptographic hash of a data block · every non-leaf node is labeled with the cryptographic hash of the labels of its child

Merkle Tree usage in Cryptography ?

Merkle trees in cryptography.

Merkle trees are an efficient example of a cryptographic commitment scheme: The root is a commitment. Leaf nodes may be revealed and proven to be part of the original commitment

Merkle Tree Usecases :

NoSQL systems(Apache Cassandra, Dynamo) ·

Bitcoin and Ethereum peer-to-peer networks ·

IPFS (InterPlanetary File System) ·

hash-based cryptography ·

Apache Wave protocol ·

ZFS file systems ·

Dat protocol ·

Zeronet ·

Git

Conclusion: Merkle Trees are a fundamental building block for decentralization because they allow for the efficient and secure verification of large amounts of data in a decentralized system. Insightful thread. Thanks for Reading
