Blockchain. A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes. [1][2][3][4] Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves).
t. e. A cryptographic hash function (CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with a fixed size of bits) that has special properties desirable for a cryptographic application: [1] the probability of a particular. n {\displaystyle n} -bit output result (hash value) for a random input string ("message") is.
Distributed hash table. A distributed hash table (DHT) is a distributed system that provides a lookup service similar to a hash table. Key–value pairs are stored in a DHT, and any participating node can efficiently retrieve the value associated with a given key. The main advantage of a DHT is that nodes can be added or removed with minimum ...
Algorand. Algorand is a proof-of-stake blockchain and cryptocurrency. [2] Algorand's native cryptocurrency is called ALGO. The SEC has filed several lawsuits [3][4][5][6] alleging ALGO is a security which is subject to regulation under U.S. securities laws, along with a few other crypto assets.
Website. microsoft.github.io /CCF /. Originally developed in 2019 by Microsoft [2] under the name Coco and later rebranded to Confidential Consortium Framework (CCF), it is an open-source framework for developing of a new category of performant applications that focuses on the optimization of secure multi-party computation and data availability.
Solidity is a programming language for implementing smart contracts [6][7] on various blockchain platforms, most notably, Ethereum. [8] Solidity is licensed under GNU General Public License v3.0. [9] Solidity was designed by Gavin Wood [10][non-primary source needed] and developed by Christian Reitwiessner, Alex Beregszaszi, and several former ...
Digital Signature Algorithm. The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem. In a public-key cryptosystem, two keys are generated: data can only be encrypted with ...
Secure multi-party computation (also known as secure computation, multi-party computation (MPC) or privacy-preserving computation) is a subfield of cryptography with the goal of creating methods for parties to jointly compute a function over their inputs while keeping those inputs private. [1] Unlike traditional cryptographic tasks, where ...
