The source of bitcoin

1. Rutgers University, a public research university in New Jersey, is concting a new study to show that bitcoin trading is not entirely privacy centric as people think
in fact, bitcoin can't help much in terms of anonymity. If you just want to pursue anonymity, it's better to use cash, which is the most anonymous means of currency trading, and its source can't be traced at all
bitcoin is a protocol, and transactions are broadcast to the distributed public ledger (blockchain). Everyone in the world can view the ledger in real time, track the transaction from the source to the destination, and do not need to register for authorization. It can be said that this has broken anyone's illusion of using bitcoin to seek privacy or anonymity
zero currency is the most anonymous digital currency in the world. However, all transaction information will be recorded on the blockchain, and the information on the blockchain is open and transparent. The digital currency issued by Puyin group is based on blockchain technology.

2. The ant S9 proced by bitmainland is the most mainstream mining machine on the market, which is famous for its low power consumption and high output. Ant mining machine S9 adopts TSMC's 16 nanometer FinFET process. TSMC comes from the agent factory of iPhone chip, and ant also applies the full custom design scheme on S9. So, this makes S9 have super computing power upgrade, let mining efficiency is higher. S9 adopts the latest generation chip bm1387 (189 chips in total), and the computing power of a single chip reaches 74gh / S. in terms of power consumption, S9 maintains at 0.08w/gh/s. (the power consumption is 0.08w/gh/s at 0.4V core voltage, and the power consumption per T computing power wall is only 100W, which is only 2.4 kwh per day. Rated calculation force: 13.5th/s ± 5%

Xuebao miner A1, miner chip is the core of miner. It is said that bitmine is the source of the whole bitcoin miner instry. Bitmine has its own powerful chip technology as early as the end of 2013. Of course, it also benefits from the joint cooperation and efforts of bitmine and other companies, and Xuebao miner is their own proct. A1 is the world's first customized mining machine, equipped with ASIC chip (bf16btc), the number of chips is as high as 576pcs, the computing power of a single chip is 84.1gh/s, and the overall computing power is as high as 49th / s ± 5%

Z4 adopts Intel al core [email protected] Cup, mining power is 265mh / S (ETH), equipped with independent graphics card 570x8, has 9 fans, and the radiator adopts Intel original radiator, power supply: station flag 2000W power supply, voltage: 12.4-12.6v.

It's not surprising that bitcoin has dropped by more than 10%, because bitcoin just rose by more than 20% not long ago, so a 10% drop can only be regarded as a correction, not a drop. But what's the fundamental reason for bitcoin's decline? Now I'd like to talk about my personal views and ideas on the issue of bitcoin for your reference and discussion only

summary of problems

the reason for bitcoin's collapse is that it rose too fast, so it led to a significant correction. It's not surprising. After all, no commodity can continue to rise, and bitcoin is the same. If you think bitcoin can still rise, I won't express my opinion, but you have to think of today's collapse, Because it is very likely that one day, you will also encounter the same slump of 10% or more as today, so investment should be cautious, especially for this kind of virtual investment procts. If you are not careful, you may lose your fortune. The above is my personal views and ideas, for your reference and discussion only

4. This still depends on the resources. Professional mining machines are very profitable, and ordinary mining machines may be suspended. Look at the flow of ore mining, we know that the super miner's income is more cattle.

5. Market method, cost method and income method are three kinds of mining right evaluation methods, including replacement cost method, discounted cash flow method, equivalent investment sharing method, geological factor evaluation method, joint risk exploration agreement method, etc
mining right refers to the right that the mining right holder is given to carry out a series of activities such as exploration, development and mining of mineral resources, including exploration right and mining right
exploration right refers to the right to explore mineral resources within the scope and time limit specified in the exploration license obtained according to law. The legal document of exploration right is exploration license, and its economic significance lies in: (1) transfer the exploration right according to law to obtain income
(2) obtain geological data of mineral resources through exploration work, recover exploration investment and obtain income through transferring geological exploration report
(3) as the exploration right holder has the priority to obtain the mining right, after the exploration right holder has the priority to obtain the mining right and becomes the mining right holder, he can further invest capital and technology to carry out mining, so as to obtain greater investment income
mining right refers to the right of the mining right holder to exploit mineral resources within the scope and time limit specified in the mining right license obtained in accordance with the law. The legal document of mining right is the license of mining right. Its economic significance lies in that it can mine mineral resources within the specified scope and period and obtain excess return on investment. It is a kind of franchise within a certain scope and period
market method, cost method and income method are three kinds of mining right evaluation methods, including replacement cost method, discounted cash flow method, equivalent investment sharing method, geological factor evaluation method, joint risk exploration agreement method, etc
mining right is an asset and an economic resource. The so-called assets are defined in accounting as the economic resources owned or controlled by an enterprise, which can be measured in currency and provide future economic benefits for the enterprise. According to the form of existence, assets are divided into tangible assets and intangible assets. Tangible assets refer to those assets with physical form, including fixed assets, current assets, long-term investment, other assets, etc; Intangible assets refer to those assets which are controlled by specific subjects and do not have independent entities, but play a long-term role in proction and operation and have profitability, including patent right, trademark right, non patented technology, land use right, goodwill, etc
the appraisal of mining right refers to the appraisal of the value of exploration right and mining right assets legally transferred in the mining right market by professional institutions and personnel in accordance with national laws and regulations and asset appraisal criteria, according to specific purposes, following appraisal principles and relevant proceres, selecting appropriate value types and using scientific methods, It is the scientific evaluation and estimation of mining right assets in the form of currency in the economic activities of the mining right market. Its essence is to judge the intrinsic or potential value of the mining right (expressed as the use value of exchange value, that is, the market value). It is an estimate of the market value of the mining right based on the mineral geological information and market information, and on the basis of multi factor analysis of the present and future market
according to the definition of mining right evaluation, mining right evaluation includes eight main elements: subject, object, basis, purpose, principle, procere, value type and method< br />

6. The emergence of digital money will affect Alipay and WeChat, but there is no competition between the three. And the choice of which way to pay is the choice of everyone. It will be very different. So there is no need to specifically change or decide what to do with the digital currency.

Through the deep use of cryptography algorithm, specially designed data structure and multi-party consensus algorithm, blockchain uses machine algorithm to solve the consistency, reliable storage and anti tampering problems of multi-party transaction records, which has a natural strong correlation with electronic data storage

first of all, the electronic contract signing records are stored in the shared account book jointly maintained by multiple parties, which can not be tampered with, denied, and of course will not be lost

secondly, electronic contract text and electronic contract elements are encrypted, including electronic contract participants. Only participants can decrypt and view the data to protect the privacy of the parties

thirdly, the machine strictly implements the pre-defined rules (smart contract), and no longer only relies on a single agreement with a third party. KYC service based on blockchain automatically checks and verifies the validity and identity of certificates, and ensures the authenticity of participants' identities on the basis of privacy

at present, the electronic contract signed on the advanced electronic contract platform has realized the distributed storage of digital fingerprints of electronic documents through the blockchain technology, which further strengthens the legal effect of the platform electronic contract

8. I thought the same way five years ago, but the real situation is that bitcoin can't be found at all now. If you want to be a miner, you need not think about the hardware requirements of the computer first, and you don't need to think about the household ones [it was possible to find them in the early days (10 years ago)]. Now all of them have special mining machines. Even if you use a special mining machine, you may not be able to dig it, especially bitcoin, which is the first virtual coin (because it was more and more difficult to dig because there were fewer and fewer coins five years ago), so the landlord should let go of this idea.
