Picture of digital currency bitcoin
1. The concept range is different. bitcoin is a kind of digital currency, and the concept of digital currency covers bitcoin
However, some digital currencies have independent issuers The biggest difference between bitcoin and other virtual currencies is that the total quantity of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 milliondigital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Bitcoin is a digital currency
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold
today's digital currencies, such as bitcoin, lettercoin and ppcoin, are electronic currencies created, issued and circulated by means of check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency
illegal digital currency
in recent years, "virtual currency" represented by bitcoin, Ethernet currency and Leyte currency has been traded centrally on some Internet platforms. With the help of financial technology, the price of these "currencies" has graally spread to investment, financing and other financial fields, which has aroused wide attention from all walks of life
not long ago, the people's Bank of China and other seven ministries and commissions jointly issued the announcement on preventing the financing risk of token issuance, which clearly regulated the relevant behaviors. Experts pointed out that "virtual currency" is not legal tender (legal currency) issued by monetary authorities, but a specific virtual commodity in essence
therefore, it is undoubtedly a great legal and economic risk to think that "virtual currency" has or will have the nature of legal tender and to carry out speculation, network fund-raising, lending and financing
the natural nature of bitcoin is decentralized, but the Central Bank of digital currency must abide by the centralized management model. Compared with bitcoin, the central bank's digital currency has a higher "currency" value, and the price of bitcoin fluctuates greatly. the central bank's digital currency ensures the payment function in daily life, and has remained relatively stable since 2014. Since the beginning of the year, the central bank has been actively engaged in the research and development of digital currency, including the active application of relevant patents
starting from the issue of digital currency, the central bank uses a two-level operating system, which first converts digital currency into banks or other operating institutions, and then to the public. Mu Changchun said the al transmission system is suitable for China's national conditions. We can not only use the existing resources to mobilize the enthusiasm of commercial banks, but also improve the acceptance of digital currency without any problem
opponents of bitcoin accuse mining of wasting a lot of resources to make meaningless coin toss, while supporters take gold mining as an example. For the bitcoin system, the biggest significance of this kind of resource consumption mining is: to distribute 21 million initial bitcoins fairly, just like to consume resources to dig gold, the only way to distribute initial bitcoins fairly is to consume resources to dig bitcoins
bitcoin has thousands of plagiarists, competitors and improvers because of its open source code. Generally, those who simply and imitate bitcoin are called Shanzhai coins, and those who add certain new features to bitcoin are called competitive coins. Some coins add other functional moles such as smart contract to bitcoin, and call themselves "second generation coins". These thousands of coins try all the initial coin distribution modes you can imagine, such as the average distribution of the initial coin to each Icelandic, the distribution of the initial coin to the nextcoin of 73 crowd funding participants, and the slow distribution of the majority of the initial coin by the developer
but the fairness of all these ways of distributing initial coins is far weaker than the mode of burning money to obtain initial bitcoin, and fairness is the core problem of a monetary system. Therefore, although bitcoin mining consumes a lot of resources, it is a reasonable economic behavior just like consuming resources to mine gold.
Many people think that bitcoin is the first digital cryptocurrency in the world, but it is not
In 1982, cryptographer and computer scientist David Chaum proposed a creative scheme blind signature: on a piece of paper, I choose a serial number that only you know, and then I sign it. Because I don't know the serial number, I can't it to another person. This idea forms the first real e-money scheme, which makes anonymous transaction possible
at present, China is experimenting with digital currency, which is legal currency with national credit as guarantee, just like paper money. In the environment of legal digital currency, it will be possible for the economic system to decide the money supply spontaneously and endogenously, issue and recover money automatically through preset and reliable program algorithm rules and on the premise of ensuring the stability of currency value. The role of the central bank may not only be the decision maker of money circulation, but also the designer of the rules of money circulation algorithm
in fact, digital currency is just a form of electronic payment to replace traditional paper money, and the specific application scenario is mobile wallet payment. Digital money is not a virtual currency that can be generated by underground mining and easy to form investment bubbles. Investment in bitcoin and other virtual currencies and electronic money is a Ponzi scheme in a strict sense. The ordinary people need to be careful to avoid leeks. p>
bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system
mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary.
