Merkle Proof
Also known as: Merkle Tree Inclusion Proof, Cryptographic Proof Path, Tree Hash Proof
A cryptographic proof that verifies the inclusion of a data element within a Merkle tree without revealing the entire dataset.
A Merkle proof is a cryptographic technique used to prove that a particular data element (e.g., a transaction) is part of a Merkle tree, without needing to reveal the entire data structure. It consists of the hash path from the leaf node to the Merkle root, allowing for efficient and secure data verification. Merkle proofs are widely used in blockchains for transaction inclusion, light client verification, and rollup proof systems. They ensure data integrity while optimizing storage and bandwidth, especially in systems like Bitcoin, Ethereum rollups, and zk-SNARKs.
