A currency is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a system of money in common use within a specific environment over time, especially for people in a nation state. Under this definition, the British Pound sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for payments to government agencies.
Commodity money is money whose value comes from a commodity of which it is made. Commodity money consists of objects having value or use in themselves as well as their value in buying goods. This is in contrast to representative money, which has no intrinsic value but represents something of value such as gold or silver, in which it can be exchanged, and fiat money, which derives its value from having been established as money by government regulation.
In economics, a commodity is an economic good, usually a resource, that specifically has full or substantial fungibility: that is, the market treats instances of the good as equivalent or nearly so with no regard to who produced them.
A virtual economy is an emergent economy existing in a virtual world, usually exchanging virtual goods in the context of an online game, particularly in massively multiplayer online games (MMOs). People enter these virtual economies for recreation and entertainment rather than necessity, which means that virtual economies lack the aspects of a real economy that are not considered to be "fun". However, some people do interact with virtual economies for "real" economic benefit.
Legal tender is a form of money that courts of law are required to recognize as satisfactory payment for any monetary debt. Each jurisdiction determines what is legal tender, but essentially it is anything which when offered ("tendered") in payment of a debt extinguishes the debt. There is no obligation on the creditor to accept the tendered payment, but the act of tendering the payment in legal tender discharges the debt.
In economics, standard of deferred payment is a function of money. It is the function of being a widely accepted way to value a debt, thereby allowing goods and services to be acquired now and paid for in the future.
In economics, a medium of exchange is any item that is widely acceptable in exchange for goods and services. In modern economies, the most commonly used medium of exchange is currency. Most forms of money are categorised as mediums of exchange, including commodity money, representative money, cryptocurrency, and most commonly fiat money. Representative and fiat money most widely exist in digital form as well as physical tokens, for example coins and notes.
The Swiss franc is the currency and legal tender of Switzerland and Liechtenstein. It is also legal tender in the Italian exclave of Campione d'Italia which is surrounded by Swiss territory. The Swiss National Bank (SNB) issues banknotes and the federal mint Swissmint issues coins.
Exonumia are numismatic items other than coins and paper money. This includes "Good For" tokens, badges, counterstamped coins, elongated coins, encased coins, souvenir medallions, tags, wooden nickels and other similar items. It is an aspect of numismatics and many coin collectors are also exonumists.
The vatu is the currency of Vanuatu. Vanuatu is, by population, the fourth smallest country in the world, after Barbados,Tonga, and the Seychelles to have its own currency and monetary policy. The vatu has no subdivisions.
Token money, or token, is a form of money that has a lesser intrinsic value compared to its face value. Token money is anything that is accepted as money, not due to its intrinsic value but instead because of custom or legal enactment. Token money costs less to produce than its face value. A banknote, e.g. a five-pound note, is token money because despite its value being 5 pounds it only costs significantly less to produce. A gold coin is not considered token money. The Token money system has been adopted in many businesses around the world as an effective way to exchange value between companies and customers. Token money as a system is predominantly used in mobile games, but is also used in the realm of e-commerce. Token money is similar to fiat money which also has little intrinsic value, however they differ in that token money is a limited legal tender. The adoption of token money has improved transaction efficiency, as the practicalty of transacting with sums of gold poses a larger security risk. In a commodity economy, money is a measure of the value of goods and services (prices) within a sovereign country or the same economy, as well as a particular commodity to pay off debts. The token is also used as a medium of exchange, as a store of value, and as a unit of account. Digital currencies using decentralized blockchain technology are also a form of token money.
The history of money is the development over time of systems for the exchange, storage, and measurement of wealth. Money is a means of fulfilling these functions indirectly and in general rather than directly, as with barter.
In numismatics, token coins or trade tokens are coin-like objects used instead of coins. The field of token coins is part of exonumia and token coins are token money. Their denomination is shown or implied by size, color or shape. They are often made of cheaper metals like copper, pewter, aluminium, brass and tin, or non-metals like bakelite, leather and porcelain.
The Cook Islands dollar was the former currency of the Cook Islands, which now uses the New Zealand dollar, although some physical cash issued for the Cook Islands dollar remains in use. The dollar was subdivided into 100 cents, with some older 50-cent coins carrying the denomination as "50 tene".
A certificate of authenticity (COA) is a seal or small sticker on a proprietary computer program, t-shirt, jersey, or any other memorabilia or art work, especially in the world of computers and sports. It is commonly a seal on paper authenticating a specific art work which and is made to demonstrate that the item is authentic.
Virtual currency, or virtual money, is a digital currency that is largely unregulated, issued and usually controlled by its developers, and used and accepted electronically among the members of a specific virtual community. In 2014, the European Banking Authority defined virtual currency as "a digital representation of value that is neither issued by a central bank or a public authority, nor necessarily attached to a fiat currency but is accepted by natural or legal persons as a means of payment and can be transferred, stored or traded electronically." A digital currency issued by a central bank is referred to as a central bank digital currency.
Money is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular country or socio-economic context. The primary functions which distinguish money are: medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment.
Ethereum is a decentralized blockchain with smart contract functionality. Ether is the native cryptocurrency of the platform. Among cryptocurrencies, ether is second only to bitcoin in market capitalization. It is open-source software.
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. NFTs can be created by anybody and require few or no coding skills 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.
Colored Coins is an open-source protocol built on the Bitcoin 2.0 that allows users to represent and manipulate immutable digital resources on top of Bitcoin transactions. They are a class of methods for representing and maintaining real-world assets on the Bitcoin blockchain, which may be used to establish asset ownership. Colored coins are bitcoins with a mark on them that specifies what they may be used for. Colored coins are also considered the initial step toward NFTs built on top of the Bitcoin network.
