Merkle Proof

Cryptography

A Merkle Proof, fundamentally, establishes data integrity within a larger dataset without revealing the entire dataset itself; this is achieved through a hierarchical hashing structure, where each non-leaf node is the hash of its child nodes. In cryptocurrency applications, it verifies the inclusion of a specific transaction within a block, crucial for light clients that do not store the full blockchain. The process minimizes data transmission requirements, enhancing scalability and efficiency in verifying blockchain state, particularly relevant for layer-2 solutions and sidechains.
