extended data
at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investment company
digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability
1. Whether the source code is open
2. Whether you can trade freely on the trading platform
3. Whether the information of the founding operation team is open and transparent
4. Whether the quantity is constant
bitcoin, Ruitai coin, Laite coin, doggy coin, thousand gold card and other mainstream digital cryptocurrencies all have these conditions.
the digital currency launched by the central bank is a national sovereign currency, which is based on the digitalization of RMB. This is a piece of data generated by a complex algorithm, which contains blockchain and encryption technology, making it unique. The payment of Alipay and WeChat is not digital money, but only based on the payment realized by electronic accounts. Compared with the current pattern of "payment transfer collection" with the help of third-party payment, what digital currency needs to achieve is "decentralization", that is, to cancel the transfer link and directly hand over the money from the payer's account to the payee, so as to rece the payment cost in currency circulation
types of digital currency
according to different issuing or consensus mechanisms, it can be divided into four categories:
1, proof of work (POW)
proof of work. The system rewards are obtained through the mining of computing power to complete the issuance and distribution of currency. More work, more gain. Such as bitcoin, lightcoin (LTC)
the advantage is that the mining cost can form a monetary price support to a certain extent, and the disadvantage is that energy consumption and environmental protection are criticized< 2. Proof of stake (POS). Allocate the newly generated currency or interest according to the amount and time of cryptocurrency you hold. Such as dash and Neo
compared with pow, POS is more energy-saving, but it increases the security risk
3. The evolution scheme of delegated proof of stake (dpos)
POS. Similar to the voting mechanism of the board of directors, through the election of representatives to vote and make decisions, n accounting nodes are elected to create, verify, sign and supervise each other. Such as the grapefruit coin (EOS)
the advantage is high efficiency, but the problem is that it presents a semi centralized state
4. POW + POS hybrid mechanism
POW is mainly used to issue currency, and POS is used to maintain the system. For example, PPC
according to the project type, it can also be divided into four categories:
1. Currency category
digital currency issued for the purpose of transfer, payment and value storage. For example, bitcoin, bitcoin cash (BCH), Monroe (XmR), and grin
2. Public chain currency, that is, the digital currency issued by public chain projects, is generally the "fuel" for the application projects to run on the public chain. Such as eth, grapefruit coin, TRX and ont
3. Application token, that is, digital currency issued by decentralized application projects, is equivalent to equity or points. For example, OMG (payment application), GXC (data application), 1st (game application)
4. Platform currency, that is, the digital currency issued by the digital currency exchange, is equivalent to equity, points or fuel. For example, BNB, HT and okb.
in the past, we used precious metals as currency. Because precious metal proction is not high, the speed of new money increase is limited, and the economy is growing, the market needs more money to let the goods flow as much as possible. There is value when there is demand. In this sense, the value of precious metals in making other things is secondary. The economy needs money to circulate goods, and this demand is the main one. However, if the proction of precious metals is limited, and the precious metal currencies in circulation will withdraw from the market for various reasons, then even the newly made precious metal currencies have the same or even higher value
why does bitcoin keep its value? BTC (short for bitcoin) exists in a huge P2P network. Bitcoin group has recognized an algorithm. Under current conditions, only about 6 new BTCs will be generated per hour. At present, there are 50 new BTCs in each group. That is to say, in this world, only about 300 BTCs are generated per hour. This output will also be limited by the difficulty automatically adjusted by the network. You can't speed up money proction by modifying everyone's client algorithm and parameters (client is open source). Counterfeit currency will be discarded by the network (unless you can control most of the network nodes)
what is the value of BTC itself
the value of BTC is the trading channel itself. A new set of BTCs provides a mathematical guarantee to transfer old BTCs from one account to another. The price behind this security guarantee is a lot of computing power. It takes a lot of energy to proce such a safe passage, so the whole BTC user group will reward the mint (currently 50 BTC), which will become 25 BTC after December 2012, and it will be halved every four years
to put it simply, my understanding is that all BTCs in the world are generated by the energy of running computers. Their total value (up to now, there are about 12W groups of BTCs proced, 50 in each group, and the market price is about US $7.3), should be less than the total market value of consumed energy. However, I think most of the energy used to proce BTC is wasted resources< br />4
