Uniswap
Uniswap is a decentralized cryptocurrency exchange that uses a set of smart contracts (liquidity pools) to execute trades on its exchange. It's an open source project and falls into the category of a DeFi product (Decentralized finance) because it uses smart contracts to facilitate trades. The protocol facilitates automated transactions between cryptocurrency tokens on the Ethereum blockchain through the use of smart contracts. , Uniswap was estimated to be the largest decentralized exchange and the fourth-largest cryptocurrency exchange overall by daily trading volume. History Uniswap was created on November 2, 2018 by Hayden Adams, a former mechanical engineer at Siemens. The Uniswap company received investments from venture capital firms, including Andreessen Horowitz, Paradigm Venture Capital, Union Square Ventures LLC and ParaFi. Uniswap’s average daily trading volume was US$220 million in October 2020. Traders and investors have utilized Uniswap because of its usage in ...

Decentralized Exchange
Decentralized finance (often stylized as DeFi) offers financial instruments without relying on intermediaries such as brokerages, exchanges, or banks by using smart contracts on a blockchain. DeFi platforms allow people to lend or borrow funds from others, speculate on price movements on assets using derivatives, trade cryptocurrencies, insure against risks, and earn interest in savings-like accounts. DeFi uses a layered architecture and highly composable building blocks. Some applications promote high interest rates but are subject to high risk. History Decentralized exchanges (abbreviated DEXs) are alternative payment ecosystems with new protocols for financial transactions that emerged within the framework of decentralized finance, which is part of blockchain technology and FinTech. CEXs, DEXs and DEX aggregators are all built on the multi-layered DeFi architecture or components, where each layer serves a well-defined purpose. (See Figure: ''Multi-layered Architecture of t ...

Decentralized Network Protocol
Decentralized computing is the allocation of resources, both hardware and software, to each individual workstation, or office location. In contrast, centralized computing exists when the majority of functions are carried out, or obtained from a remote centralized location. Decentralized computing is a trend in modern-day business environments. This is the opposite of centralized computing, which was prevalent during the early days of computers. A decentralized computer system has many benefits over a conventional centralized network. Desktop computers have advanced so rapidly, that their potential performance far exceeds the requirements of most business applications. This results in most desktop computers remaining idle (in relation to their full potential). A decentralized system can use the potential of these systems to maximize efficiency. However, it is debatable whether these networks increase overall effectiveness. All computers have to be updated individually with new s ...

Constant Function Market Maker
A constant-function market maker (CFMM) is a market maker with the property that that the amount of any asset held in its inventory is completely described by a well-defined function of the amounts of the other assets in its inventory. As a result, both wealth and liquidity are known and fixed given relative prices. This has made these rules popular in prediction markets (fixed cost of information) and decentralized finance (known price exposure). History An early description of a CFMM was published by economist Robin Hanson in ''"Logarithmic Market Scoring Rules for Modular Combinatorial Information Aggregation"'' (2002). Early literature referred to the broader class of "automated market makers", including that of the Hollywood Stock Exchange founded in 1999; the term "constant-function market maker" was introduced in ''"Improved Price Oracles: Constant Function Market Makers"'' (Angeris & Chitra 2020). Rumored to first be seen in production on a Minecraft server in 2012, CFMMs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethereum
Ethereum is a decentralized, open-source blockchain with smart contract functionality. Ether (Abbreviation: ETH; sign: Ξ) is the native cryptocurrency of the platform. Among cryptocurrencies, ether is second only to bitcoin in market capitalization. Ethereum was conceived in 2013 by programmer Vitalik Buterin. Additional founders of Ethereum included 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 permanent and immutable decentralized applications onto it, with which users can interact. Decentralized finance (DeFi) applications provide a broad array of financial services without the need for typical financial intermediaries like brokerages, exchanges, or banks, such as allowing cryptocurrency users to borrow against their holdings or lend them out for interest. Ethereum also allows users to create and exchange NFTs, which are un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solidity
Solidity is an object-oriented programming language for implementing smart contracts on various blockchain platforms, most notably, Ethereum. It was developed by Christian Reitwiessner, Alex Beregszaszi, and several former Ethereum core contributors. Programs in Solidity run on Ethereum#Virtual machine, Ethereum Virtual Machine. History Solidity was proposed in August 2014 by Gavin Wood; the language was later developed by the Ethereum project's Solidity team, led by Christian Reitwiessner. Solidity is the primary language on Ethereum as well as on other private blockchains, such as the enterprise-oriented Hyperledger Fabric blockchain. SWIFT deployed a proof of concept using Solidity running on Hyperledger Fabric. Description Solidity is a statically typed programming language designed for developing smart contracts that run on the Ethereum#Virtual machine, Ethereum Virtual Machine (EVM). Solidity uses ECMAScript-like syntax which makes it familiar for existing web develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptocurrency Companies
A cryptocurrency, crypto-currency, or crypto is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it. It is a decentralized system for verifying that the parties to a transaction have the money they claim to have, eliminating the need for traditional intermediaries, such as banks, when funds are being transferred between two entities. Individual coin ownership records are stored in a digital ledger, which is a computerized database using strong cryptography to secure transaction records, control the creation of additional coins, and verify the transfer of coin ownership. Despite their name, cryptocurrencies are not considered to be currencies in the traditional sense, and while varying treatments have been applied to them, including classification as commodities, securities, and currencies, cryptocurrencies are generally viewed as a distinct ...

Fork (software Development)
In software engineering, a project fork happens when developers take a copy of source code from one software package and start independent development on it, creating a distinct and separate piece of software. The term often implies not merely a development branch, but also a split in the developer community; as such, it is a form of schism. Grounds for forking are varying user preferences and stagnated or discontinued development of the original software. Free and open-source software is that which, by definition, may be forked from the original development team without prior permission, and without violating copyright law. However, licensed forks of proprietary software (''e.g.'' Unix) also happen. Etymology The word "fork" has been used to mean "to divide in branches, go separate ways" as early as the 14th century. In the software environment, the word evokes the fork system call, which causes a running process to split itself into two (almost) identical copies that (ty ...

Market Maker
A market maker or liquidity provider is a company or an individual that quotes both a buy and a sell price in a tradable asset held in inventory, hoping to make a profit on the ''bid–ask spread'', or ''turn.'' The benefit to the firm is that it makes money from doing so; the benefit to the market is that this helps limit price variation ( volatility) by setting a limited trading price range for the assets being traded. In U.S. markets, the U.S. Securities and Exchange Commission defines a "market maker" as a firm that stands ready to buy and sell stock on a regular and continuous basis at a publicly quoted price. A Designated Primary Market Maker (DPM) is a specialized market maker approved by an exchange to guarantee that they will take a position in a particular assigned security, option, or option index. In currency exchange Most foreign exchange trading firms are market makers, as are many banks. The foreign exchange market maker both buys foreign currency from clients and ...

Liquidity Pool
In finance, a dark pool (also black pool) is a private forum (alternative trading system or ATS) for trading securities, derivatives, and other financial instruments."The New Financial Industry" (March 30, 2014). 65 ''Alabama Law Review'' 567 (2014); Temple University Legal Studies Research Paper No. 2014-11; via SSRN. Liquidity on these markets is called dark pool liquidity. The bulk of dark pool trades represent large trades by s that are offered away from pub ...
