ICON (blockchain Platform)
ICON is a decentralized, open-source blockchain with smart contract functionality. ICX is the native cryptocurrency of the platform. History ICON was founded in 2017 by Min Kim of the Switzerland-based ICON Foundation. According to the ICON white paper, the purpose for ICON was to introduce a new era of decentralization and hyper connect Korea. ICON's initial coin offering (ICO) in September 2017 raised 150,000 ETH (approximately US$43 million at the time). At the time of launch, ICON was supported by various public and private organizations, including the Seoul Metropolitan Government in South Korea, and the Line Corporation in Japan. Applications Decentralized finance Decentralized finance (DeFi) is a use case of ICON. It offers traditional financial instruments in a decentralized architecture, outside of companies' and governments' control, such as money market funds which let users earn interest. Decentralized finance applications can be accessed through a Web3-ena ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decentralization
Decentralization or decentralisation is the process by which the activities of an organization, particularly those related to planning and decision-making, are distributed or delegated away from a central, authoritative location or group and given to smaller factions within it. Concepts of decentralization have been applied to group dynamics and management science in private businesses and organizations, political science, law and public administration, technology, economics and money. History The word "''centralisation''" came into use in France in 1794 as the post-French Revolution, Revolution French Directory leadership created a new government structure. The word "''décentralisation''" came into usage in the 1820s. "Centralization" entered written English in the first third of the 1800s; mentions of decentralization also first appear during those years. In the mid-1800s Alexis de Tocqueville, Tocqueville would write that the French Revolution began with "a push towards ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web3
Web3 (also known as Web 3.0) is an idea for a new iteration of the World Wide Web which incorporates concepts such as decentralization, blockchain technologies, and token-based economics. This is distinct from Tim Berners-Lee's concept of the Semantic Web. Some technologists and journalists have contrasted it with Web 2.0, in which they say user-generated content is controlled by a small group of companies referred to as Big Tech. The term "web3" was coined in 2014 by Ethereum co-founder Gavin Wood, and the idea gained interest in 2021 from cryptocurrency enthusiasts, large technology companies, and venture capital firms. The concepts of web3 were first represented in 2013. Critics have expressed concerns over the centralization of wealth to a small group of investors and individuals, or a loss of privacy due to more expansive data collection. Billionaires like Elon Musk and Jack Dorsey have argued that web3 only serves as a buzzword or marketing term. Background Web ...

Alternative Currencies
A complementary currency is a currency or medium of exchange that is not necessarily a national currency, but that is thought of as supplementing or complementing national currencies. Complementary currencies are usually not legal tender and their use is based on agreement between the parties exchanging the currency. According to Jérôme Blanc of Laboratoire d'Économie de la Firme et des Institutions, complementary currencies aim to protect, stimulate or orientate the economy. They may also be used to advance particular social, environmental, or political goals. When speaking about complementary currencies, a number of overlapping and often interchangeable terms are in use: Local currency, local or Community currency, community currencies are complementary currencies used within a locality or other form of community (such as business-based or online communities); regional currencies are similar to local currencies, but are used within a larger geographical region; and sectoral ...

Cryptocurrencies
A cryptocurrency (colloquially crypto) is a digital currency designed to work through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it. Individual coin ownership records are stored in a digital ledger or blockchain, which is a computerized database that uses a consensus mechanism to secure E-commerce, transaction records, control the creation of additional coins, and verify the transfer of coin ownership. The two most common consensus mechanisms are proof of work and proof of stake. Despite the name, which has come to describe many of the fungibility, fungible blockchain tokens that have been created, cryptocurrencies are not considered to be Currency, currencies in the traditional sense, and varying legal treatments have been applied to them in various jurisdictions, including classification as Commodity, commodities, Security (finance), securities, and currencies. Cryptocurrencies are generally viewed as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blockchains
The blockchain is a distributed ledger with growing lists of records (''blocks'') that are securely linked together via cryptographic hashes. 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). Since each block contains information about the previous block, they effectively form a ''chain'' (compare linked list data structure), with each additional block linking to the ones before it. Consequently, blockchain transactions are resistant to alteration because, once recorded, the data in any given block cannot be changed retroactively without altering all subsequent blocks and obtaining network consensus to accept these changes. Blockchains are typically managed by a peer-to-peer (P2P) computer network for use as a public distributed ledger, where nodes collectively adhere to a consensus algorithm protocol to add and validate new transaction bloc ...

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.

Bitcoin
Bitcoin (abbreviation: BTC; Currency symbol, sign: ₿) is the first Decentralized application, decentralized cryptocurrency. Based on a free-market ideology, bitcoin was invented in 2008 when an unknown entity published a white paper under the pseudonym of Satoshi Nakamoto. Use of bitcoin as a currency began in 2009, with the release of its open-source software, open-source implementation. In 2021, Bitcoin in El Salvador, El Salvador adopted it as legal tender. It is mostly seen as an investment and has been described by some scholars as an economic bubble. As bitcoin is pseudonymous, Cryptocurrency and crime, its use by criminals has attracted the attention of regulators, leading to Legality of cryptocurrency by country or territory, its ban by several countries . Bitcoin works through the collaboration of computers, each of which acts as a Node (networking), node in the peer-to-peer bitcoin network. Each node maintains an independent copy of a public distributed ledger of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Virtual World
A virtual world (also called a virtual space or spaces) is a Computer simulation, computer-simulated environment which may be populated by many simultaneous users who can create a personal Avatar (computing), avatar and independently explore the virtual world, participate in its activities, and communicate with others. These avatars can be textual, graphical representations, or live video avatars with auditory and touch sensations. Virtual worlds are closely related to mirror worlds. In a virtual world, the User (computing), user accesses a computer-simulated world which presents Perception, perceptual stimuli to the user, who in turn can manipulate elements of the modeled world and thus experience a degree of Immersion (virtual reality)#Presence, presence. Such modeled worlds and their rules may draw from reality or fantasy worlds. Example rules are gravity, topography, animal locomotion, locomotion, real-time computer graphics, real-time actions, and communication. Communicati ...

Non-fungible Token
A non-fungible token (NFT) is a unique digital identifier that is recorded on a blockchain and is used to certify ownership and authenticity. It cannot be copied, substituted, or subdivided. The ownership of an NFT is recorded in the blockchain and can be transferred by the owner, allowing NFTs to be sold and traded. Initially pitched as a new class of investment asset, by September 2023, one report claimed that over 95% of NFT collections had zero monetary value. NFTs can be created by anybody and require little or no coding skill to create. NFTs typically contain references to digital files such as artworks, photos, videos, and audio. Because NFTs are uniquely identifiable, they differ from cryptocurrencies, which are fungible (hence the name non-fungible token). Proponents claim that NFTs provide a public certificate of authenticity or proof of ownership, but the legal rights conveyed by an NFT can be uncertain. The ownership of an NFT as defined by the blockchain has no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Financial Services
Financial services are service (economics), economic services tied to finance provided by financial institutions. Financial services encompass a broad range of tertiary sector of the economy, service sector activities, especially as concerns financial management and consumer finance. The finance industry in its most common sense concerns commercial banks that provide market liquidity, derivative (finance), risk instruments, and broker, brokerage for large public company, public companies and multinational corporations at a macroeconomics, macroeconomic scale that impacts domestic politics and foreign relations. The extragovernmental power and scale of the finance industry remains an ongoing controversy in many industrialized Western economies, as seen in the American Occupy Wall Street civil protest movement of 2011. Styles of financial institution include credit union, bank, savings and loan association, trust company, building society, brokerage firm, payment processor, many ty ...

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 ...
