Blockchain for e-money
thank you
to know the difference between them, we need to know the definition of them first
digital currency: short for digiccy, which is the abbreviation of "digital
currency", is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
blockchain: blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is essentially a decentralized database, also known as the trust machine
from the above definition, we can know that blockchain is a technology, and digital currency is a kind of virtual currency
digital currency is not equal to blockchain
many people will understand blockchain as blockchain. Here I want to correct that digital currency is not equal to blockchain. Digital currency is only an application of blockchain, and some digital currencies may not be applied to blockchain technology.
The differences between e-money and virtual money are as follows:
1. Electronic money refers to using a certain amount of cash or deposit to exchange from the issuer and obtain data representing the same amount, or through the quick payment service launched by the bank and the third party to transfer the balance in the bank through some electronic ways, so that transactions can be carried out. Strictly speaking, it is a kind of currency that consumers use the bank's Internet banking service to store value and make quick payment to the issuers of electronic currency, and make consumers trade electronically through media (two-dimensional code or hardware equipment)
Virtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum" The detailed explanation of electronic currency is as follows:1. Concept: it is an encrypted serial number representing cash, which can be used to represent the currency value of various amounts in reality. With the transformation from paper-based economy to digital economy, e-cash will become the mainstream
2. Features: anonymity, transaction cost saving, transmission cost saving, low holding risk, flexible and convenient payment, anti-counterfeiting and anti repetition, non traceability
There are two kinds of e-cash: one is based on the Internet and keeps the binary data representing the value of money in the hard disk of the computer terminal; One is the electronic wallet that keeps the monetary value in the IC card and can be circulated without the bank payment system4. Definition: consumers pay traditional money to the issuers of electronic money, and the issuers store the equal value of traditional money in the electronic devices held by consumers in electronic form
the difference between digital currency, electronic currency and virtual currency
in fact, digital currency is a kind of indexed RMB, a legal encrypted digital currency and an alternative currency in the form of electronic currency. Digital currency can be divided into two types: non cryptocurrency (e-gold, XRP) and cryptocurrency (bitcoin)
it can not be completely equivalent to the virtual currency in the virtual world, because it is often used for real goods and services transactions, not limited to online games and other virtual spaces. It is different from Alipay and WeChat, and Alipay, WeChat payment and mobile phone banks are all electronic money, not digital money. The popular digital currencies in 2016 include bitcoin, lightcoin, bitstock, etc. At present, there are thousands of digital currencies issued all over the world
virtual currency refers to the non real currency, especially the currency in the network virtual economy. The issuer is not the central bank, and it can only circulate in a specific virtual environment. In the case of the connection between virtual and reality, virtual currency has its real value. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point, roll counting of Shanda company, u-coin meter ticket launched by Sina (used for igome game), chivalrous Yuanbao (used for chivalrous road game), and grain silver (used for bixue Qingtian game). Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency. For example, bitcoin is illegal digital currency
since the beginning of the year, the relevant person in charge of the people's Bank of China has said that the future of mobile payment is bright, and the central bank is actively studying the relevant research results and practical experience at home and abroad to strive for the early issuance of digital currency. At the digital currency seminar of the people's Bank of China held on January 20, the relevant person in charge of the people's Bank of China disclosed that the central bank has set up a special research team since 2014 to conct in-depth research on the digital currency issuance and business operation framework, key technologies, circulation environment, etc., and strive to launch the digital currency issued by the central bank as soon as possible. At present, the research has achieved phased results
what benefits will digital currency bring to our lives
for this problem, the relevant person in charge of the central bank said that if the digital currency is successfully issued, it will bring many conveniences: it can effectively rece the high cost of the issuance and circulation of traditional paper money, and improve the convenience and transparency of economic transaction activities; It can rece money laundering, tax evasion and other illegal and criminal acts, enhance the central bank's control over money supply and money circulation, better support economic and social development, and help the comprehensive realization of Inclusive Finance; It helps to build a new financial infrastructure, further improve the payment system, improve the efficiency of payment and clearing, and promote the upgrading of economic quality and efficiency. More digital currencies can focus on bitMom
of course, the coin here is what we often call token, which originally means token (temporary) in computer identity authentication. With the popularity of blockchain and digital currency, people have a variety of translations for token, including token, integral, certificate, logo, indicator, etc
the understanding of token in the market can be divided into two categories
in the first category, 99% of the people think token means token, because 99.9% of the projects do the same thing. Set up a foundation, build a website, write a white paper, and then go to ICO. Because most of the projects are still in the conceptual stage, token itself has no other meaning except trading, so people call it token, which performs the function of currency to some extent
in the second category, professionals and institutions are more willing to translate token into proof of equity, or token. For example, a person's identity certificate, academic certificate, equity, bonds, points, bills, etc., are authentic and tamperable because of the proof of rights and interests. Every proof of interest becomes more secure and reliable through the protection of cryptography
therefore, blockchain is not only a technology, but also a new mode of proction and organization, even a new thinking
so, the question now is, does the blockchain project have to issue currency
answer: you may not issue currency. Not all blockchain projects need to be issued with currency, and it is not necessarily blockchain projects that issue currency
for example, the alliance chain does not need to issue coins. For example, Tencent's q-coin, in principle, is also a kind of currency, but it is not a blockchain project
therefore, the two are not related, but if they are public chains, they need to issue coins. Why
let's take bitcoin as an example. Bitcoin system as a public chain must rely on the existence of bitcoin. Public chain obtains the stability and non tamperability of its system through the nodes distributed all over the world, and these properties are the basis for the existence of public chain
imagine that if the bitcoin system is unstable or can be easily tampered with, bitcoin will be worthless. These nodes are not set up by one or several companies, otherwise they are equivalent to private chain or alliance chain. These nodes must be built dynamically by many participants. And the existence of these nodes must need some kind of incentive, otherwise why do the builders of these nodes want to participate in your system. And this kind of incentive must be integrated with the blockchain system, and it must be money
then why is it currency, not legal currency, such as RMB, as an incentive
if RMB is used as incentive, because RMB should be stored in the RMB account, and the account itself is centralized, so it's easy to be controlled. Just think about why domestic bitcoin exchanges are so afraid of the central bank, and they are afraid of being weaned. In addition, RMB can't react with smart contracts within the blockchain
the electronic currency issued by the central bank can not be used as the original currency and incentive of a blockchain system. Why
if the central bank or a rich person wants to destroy a project, they just need to take out enough e-money to do enough nodes and attack 51%. Therefore, it is impossible to use the e-money issued by the central bank as the original currency and incentive blockchain system. However, blockchain projects with independent native currency and incentives have no such worries
If a person or organization wants to get enough nodes to carry out 51% attacks, it must first get more than 50% enough coins, and the amount of coins in the market is certain, so before it gets enough coins, the soaring price will make it hard for him to bear
therefore, a public chain project must have money. A public chain project without money is like a castrated person
in addition, only through the token and reasonable stimulation of output, can the proction relationship be changed and the value of blockchain be brought into play. Therefore, the project must have token, which can promote the development of the project faster. Token solves the problem of incentive and consensus, and incentive solves the problem of autonomy. The positive autonomous economic ecosystem and the underlying technology of blockchain are a perfect combination.
