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).
The blockchain-based database is a combination of traditional database and distributed database where data is transacted and recorded via Database Interface[1] (also known as Compute Interface) [2] supported by multiple-layers of blockchains. [3] The database itself is shared in the form of an encrypted /immutable ledger which makes the ...
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 ...
Decentralized application. A decentralised application (DApp,[1] dApp, [2] Dapp, or dapp) is an application that can operate autonomously, typically through the use of smart contracts, that run on a decentralized computing, blockchain or other distributed ledger system. [3] Like traditional applications, DApps provide some function or utility ...
solidproject.org. Solid (So cial Li nked D ata) [1] is a web decentralization project led by Sir Tim Berners-Lee, the inventor of the World Wide Web, originally developed collaboratively at the Massachusetts Institute of Technology (MIT). The project "aims to radically change the way Web applications work today, resulting in true data ownership ...
Proof of work. Proof of work (PoW) is a form of cryptographic proof in which one party (the prover) proves to others (the verifiers) that a certain amount of a specific computational effort has been expended. [1] Verifiers can subsequently confirm this expenditure with minimal effort on their part.
A distributed ledger (also called a shared ledger or distributed ledger technology or DLT) is a system whereby replicated, shared, and synchronized digital data is geographically spread (distributed) across many sites, countries, or institutions. [1] In contrast to a centralized database, a distributed ledger does not require a central ...
Web3 (also known as Web 3.0[1][2][3]) is an idea for a new iteration of the World Wide Web which incorporates concepts such as decentralization, blockchain technologies, and token-based economics. [4] Some technologists and journalists have contrasted it with Web 2.0, wherein they say data and content are centralized in a small group of ...
