In this interpretation a smart contract is any kind of computer program which uses a blockchain. A smart contract also can be regarded as a secured stored procedure, as its execution and codified effects (like the transfer of tokens between parties) cannot be manipulated without modifying the blockchain itself. In this interpretation, the ...
Web3 (also known as Web 3.0) [1] [2] [3] was an idea for a new iteration of the World Wide Web which incorporates concepts such as decentralization, blockchain technologies, and token-based economics. [4]
A decentralised application (DApp, [1] dApp, [2] Dapp, or dapp [3]) 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. [4] Like traditional applications, DApps provide some function or utility to its users.
DeFi applications are typically accessed through a Web3-enabled browser extension or application, such as MetaMask, which allows users to directly interact with the Ethereum blockchain through a website. [78] Many of these DApps can connect and work together to create complex financial services. [79] Examples of DeFi platforms include MakerDAO ...
The Semantic Web, sometimes known as Web 3.0 (not to be confused with Web3), is an extension of the World Wide Web through standards [1] set by the World Wide Web Consortium (W3C). The goal of the Semantic Web is to make Internet data machine-readable .
The bitcoin design has inspired other applications [3] [2] and blockchains that are readable by the public and are widely used by cryptocurrencies. The blockchain may be considered a type of payment rail. [8] Private blockchains have been proposed for business use.
Polkadot is a decentralized, nominated proof-of-stake blockchain with smart contract functionality. The cryptocurrency native to the blockchain is the DOT.. It is designed to allow blockchains to exchange messages and perform transactions with each other without a trusted third-party.
The Ethereum blockchain popularized smart contracts, which are the basis of DeFi, in 2017. Other blockchains have since implemented smart contracts. As of 2021, MakerDAO was a prominent lending DeFi platform based on a stablecoin that was established in 2017. [7] [8] It allowed users to borrow DAI, a token pegged to the US dollar.
