  2. Merkle tree - Wikipedia

    en.wikipedia.org/wiki/Merkle_tree

    Suggestions have been made to use hash trees in trusted computing systems. [11] The initial Bitcoin implementation of Merkle trees by Satoshi Nakamoto applies the compression step of the hash function to an excessive degree, which is mitigated by using Fast Merkle Trees. [12]

  3. Merkle signature scheme - Wikipedia

    en.wikipedia.org/wiki/Merkle_signature_scheme

    In hash-based cryptography, the Merkle signature scheme is a digital signature scheme based on Merkle trees (also called hash trees) and one-time signatures such as the Lamport signature scheme. It was developed by Ralph Merkle in the late 1970s [1] and is an alternative to traditional digital signatures such as the Digital Signature Algorithm ...

    He co-invented the Merkle–Hellman knapsack cryptosystem, invented cryptographic hashing (now called the Merkle–Damgård construction based on a pair of articles published 10 years later that established the security of the scheme), and invented Merkle trees. The Merkle–Damgård construction is at the heart of many hashing algorithms. [4 ...

  6. Commitment scheme - Wikipedia

    en.wikipedia.org/wiki/Commitment_scheme

    A common example of a practical partial reveal scheme is a Merkle tree, in which a binary hash tree is created of the elements of . This scheme creates commitments that are O ( 1 ) {\displaystyle O(1)} in size, and proofs that are O ( log 2 ⁡ n ) {\displaystyle O(\log _{2}{n})} in size and verification time.
