Optimism (blockchain)
Ethereum is a decentralized blockchain with smart contract functionality. Ether (abbreviation: ETH) is the native cryptocurrency of the platform. Among cryptocurrencies, ether is second only to bitcoin in market capitalization. It is open-source software. Ethereum was conceived in 2013 by programmer Vitalik Buterin. Other founders include Gavin Wood, Charles Hoskinson, Anthony Di Iorio, and Joseph Lubin. In 2014, development work began and was crowdfunded, and the network went live on 30 July 2015. Ethereum allows anyone to deploy decentralized applications onto it, with which users can interact. Decentralized finance (DeFi) applications provide financial instruments that do not directly rely on financial intermediaries like brokerages, exchanges, or banks. This facilitates borrowing against cryptocurrency holdings or lending them out for interest. Ethereum also allows users to create and exchange non-fungible tokens (NFTs), which are tokens that can be tied to unique digital ...

Vitalik Buterin
Vitaly Dmitrievich Buterin (; born 31 January 1994), better known as Vitalik Buterin (), is a Canadian computer programmer and co-founder of Ethereum. Buterin became involved with cryptocurrency early in its inception, co-founding ''Bitcoin Magazine'' in 2011. In 2015, Buterin deployed the Ethereum blockchain with Gavin Wood, Charles Hoskinson, Anthony Di Iorio, and Joseph Lubin (entrepreneur), Joseph Lubin. Early life and education Buterin was born in Kolomna, Russia, to a Russian family. His father, Dmitry, was a computer scientist. He and his parents lived in the area until the age of six, when his parents Immigration to Canada, emigrated to Canada in search of better employment opportunities. While in grade three of elementary school in Canada, Buterin was placed into a class for gifted children and was drawn to mathematics, programming, and economics. Buterin then attended The Abelard School, a private high school in Toronto. Buterin learned about Bitcoin from his father ...

Smart Contract
A smart contract is a computer program or a Transaction Protocol Data Unit, transaction protocol that is intended to automatically execute, control or document events and actions according to the terms of a contract or an agreement. The objectives of smart contracts are the reduction of need for trusted intermediators, arbitration costs, and fraud losses, as well as the reduction of malicious and accidental exceptions. Smart contracts are commonly associated with cryptocurrency , cryptocurrencies, and the smart contracts introduced by Ethereum are generally considered a fundamental building block for decentralized finance (DeFi) and non-fungible token (NFT) applications. The original Ethereum white paper by Vitalik Buterin in 2014 describes the Bitcoin protocol as a weak version of the smart contract concept as originally defined by Nick Szabo, and proposed a stronger version based on the Solidity language, which is Turing complete. Since then, various cryptocurrencies have suppo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decentralized Finance
Decentralized finance (often stylized as DeFi) provides financial instruments and services through smart contracts on a programmable, permissionless blockchain. This approach reduces the need for intermediaries such as brokerages, exchanges, or banks. DeFi platforms enable users to lend or borrow funds, speculate on asset price movements using derivatives, trade cryptocurrencies, insure against risks, and earn interest in savings-like accounts. The DeFi ecosystem is built on a layered architecture and highly composable building blocks. While some applications offer high interest rates, they carry high risks. Coding errors and hacks are a common challenge in DeFi. DeFi protocols exhibit varying degrees of decentralization, with truly decentralized protocols potentially acting as neutral infrastructure, while false decentralization leaves protocols open to manipulation and fraud or to being regulated as financial intermediaries.

Decentralized Application
A decentralised application (DApp, dApp, Dapp, or dapp) is an Application software, application that can operate autonomously, typically through the use of smart contracts, that run on a decentralized computing, blockchain or other distributed ledger system. Like traditional applications, DApps provide some function or utility to its users. However, unlike traditional applications, DApps operate without human intervention and are not owned by any one entity, rather DApps distribute Cryptocurrency#Crypto token, tokens that represent ownership. These tokens are distributed according to a programmed algorithm to the users of the system, diluting ownership and control of the DApp. Without any one entity controlling the system, the application is therefore Decentralization, decentralised. Decentralised applications have been popularised by Distributed ledger, distributed ledger technologies (DLT), such as the Ethereum or Cardano (blockchain platform), Cardano blockchain, on which DApps ...

Crowdfunding
Crowdfunding is the practice of funding a project or venture by raising money from a large number of people, typically via the internet. Crowdfunding is a form of crowdsourcing and Alternative Finance, alternative finance, to fund projects "without standard financial intermediaries". Mollick, E. (2014). ''The dynamics of crowdfunding: An exploratory study.'' Journal of Business Venturing. Vol. 29, pp. 1–16. In 2015, over was raised worldwide by crowdfunding. Although similar concepts can also be executed through mail-order subscriptions, benefit events, and other methods, the term crowdfunding refers to internet-mediated registries. This modern crowdfunding model is generally based on three types of actors – the project initiator who proposes the idea or project to be funded, individuals or groups who support the idea, and a moderating organization (the "platform") that brings the parties together to launch the idea. The term crowdfunding was coined in 2006 by entrepreneur an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Open-source software (OSS) is Software, computer software that is released under a Open-source license, license in which the copyright holder grants users the rights to use, study, change, and Software distribution, distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative, public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to online collaboration, participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2024 estimate of the value of open-source software to firms is $8.8 trillion, as firms would need to spend 3.5 times the amount they currently do without the use of open source software. Open-source code can be used for studying and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Market Capitalization
Market capitalization, sometimes referred to as market cap, is the total value of a publicly traded company's outstanding common shares owned by stockholders. Market capitalization is equal to the market price per common share multiplied by the number of common shares outstanding. Description Market capitalization is sometimes used to rank the size of companies. It measures only the equity component of a company's capital structure, and does not reflect management's decision as to how much debt (or leverage) is used to finance the firm. A more comprehensive measure of a firm's size is enterprise value (EV), which gives effect to outstanding debt, preferred stock, and other factors. For insurance firms, a value called the embedded value (EV) has been used. It is also used in ranking the relative size of stock exchanges, being a measure of the sum of the market capitalizations of all companies listed on each stock exchange. The total capitalization of stock markets or eco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
