Virtual currency tracking technology

1. virtual currency needs to be developed by a professional development team, not by itself. The development of virtual currency technology has become mature, there is no difficulty in technology, but the positioning of virtual currency is the biggest problem. In fact, bitcoin, Ruitai coin, Laite coin and doggy coin are not very different in technology. The difference is that they have different names, different algorithms, different numbers and different positioning.

Virtual currency fraud calls 110 directly

many departments, such as the China Banking and Insurance Regulatory Commission, the central office of information technology, the Ministry of public security and so on, issued risk tips, saying that some criminals, under the banner of "financial innovation" and "blockchain", absorbed funds by issuing the so-called "virtual currency", "virtual assets" and "digital assets", thus infringing the legitimate rights and interests of the public

this kind of activity is not really based on blockchain technology, but on the hype of blockchain concept, illegal fund-raising, pyramid selling and fraud. In essence, it is a Ponzi scheme of "repaying the old by borrowing the new", which is difficult to maintain the long-term operation of funds

the public should treat the blockchain rationally, not blindly believe the promises, establish a correct monetary concept and investment concept, and effectively improve the risk awareness. Report to the public security organ in time after being cheated

extended data:

the first is the obvious networking and cross-border of virtual currency. Relying on the Internet and chat tools for transactions, and using online payment tools to balance funds, the risks spread widely and spread quickly. Some lawless elements set up websites by renting overseas servers to carry out activities for domestic residents and control illegal activities remotely

some indivials claim that they have obtained the investment quota of overseas high-quality blockchain projects in the chat tool group and can invest on their behalf, which is most likely fraud. Most of these illegal funds flow overseas, which makes it very difficult to supervise and trace

followed by deception, temptation and concealment. They use hot concepts to hype, fabricate various "tall and tall" theories, and some also use celebrity "big V" platforms to publicize. They use airdrop "candy" as temptation to claim that "currency value only rises but not falls", "investment cycle is short, income is high, and risk is low", which has strong bewitching

in practice, criminals illegally make huge profits by manipulating the price trend of the so-called virtual currency, setting profit and withdrawal threshold. In addition, some criminals also issue tokens under the guise of ICO, IFO, IEO, etc., or hype virtual currency in the way of IMO under the banner of sharing economy, which has strong concealment and confusion

finally, there are many kinds of illegal risks in this kind of behavior. Through public publicity, the illegal elements attract the public to invest funds, lure investors and development personnel to join, and constantly expand the fund pool with the t of currency appreciation and development offline profits, which has the characteristics of illegal fund-raising, pyramid selling, fraud and other illegal acts

Background: the financial application of blockchain technology brings high investment value

2018 China international big data instry Expo opened in Guiyang City, Guizhou Province on the 26th. At the meeting, it was pointed out that China will vigorously develop the digital economy in the future, deeply implement the action plan for the development of big data and cloud computing, and deeply study blockchain technology and application. Especially in the field of finance, the landing application has become the focus of the scientific and financial circles

1. The value source of blockchain is that it can perfectly solve the pain points of the current financial instry:

in today's asset securitization, insurance, supply chain finance, commodity trading, asset custody and other financial scenarios, e to many participants, high cost of credit evaluation, low settlement efficiency of intermediary institutions and other reasons, Traditional financial service methods are difficult to effectively solve the long-standing core pain points in the instry, such as information asymmetry, complex and rendant processes, and high information verification cost

2. Why can blockchain solve the above pain points:

blockchain technology integrates many basic technologies, such as distributed accounting, tamper proof, built-in contract, etc., and constructs a trust building mechanism with lower cost. The financial application based on blockchain technology can realize the ability of all market participants to obtain all transaction information and asset ownership records in the market without discrimination, and effectively solve the problem of information asymmetry; Smart contract embedding reces the error rate of payment and settlement, simplifies the process and improves efficiency; At the same time, based on transparent information and brand-new trust mechanism, there is no need to spend manpower, material resources and financial resources to confirm information among participants, which will greatly rece the trust cost between institutions, and then rece the price of financial services and transaction costs

3. The application of blockchain technology in the financial field mainly includes the following aspects:

① digital currency

among which bitcoin is the most famous. On the basis of bitcoin, a large number of other types of decentralized digital currencies have been derived. Such as: the heyday of bits

Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment for both parties without the help of the banking system, which can greatly improve the speed and rece the cost

③ digital bills

④ bank credit management: the advantage of blockchain is that it can rely on program algorithm to automatically record credit related information and store it on every computer in the blockchain network, with transparent information, tamper proof and low cost

The major financial institutions and exchanges in Europe and the United States have explored the application research of building the next generation of financial asset trading platform based on blockchain technology

4. The development prospect of blockchain. The future development of blockchain technology will have the most vitality with alliance chain as the entry point, and will have a significant effect and far-reaching impact on the transformation of traditional financial instry pain points

in response to the good investment prospects of blockchain, domestic enterprises such as Alibaba, Jingdong and Netcom have entered the market. The application of financial scenarios based on blockchain technology not only brings us security and convenience, but also provides us with broader investment space. The rise and price surge of digital currency represented by bitcoin (bitcoin was about RMB 20 cents when it was first listed in 2009, and its current price is about US $7300!) It's the best proof that people with a keen sense of smell have made a lot of money from it

Abstract: This is an encrypted digital currency based on the bitcoin developed by Nakamoto Tsung, which improves and adds many new functions, such as the double-layer reward system network, also known as the main node network. It also includes anonymous payment to improve the interchangeability (bitage) and real-time payment function docking to realize real-time transaction confirmation without relying on the authority of the center (P2P mall)

In 2009, Nakamoto put forward the concept of bitcoin. Since then, bitcoin has spread rapidly in mainstream applications and commercial uses, becoming the first digital currency to attract a large number of users, which is a milestone in the history of digital currency. However, from the perspective of completing the transaction, we can find an important problem, that is, it takes too long for bitcoin block to confirm the transaction. Traditional payment companies have found a solution to enable the buyer and the seller to realize zero confirmation of bitcoin transaction, but this solution usually requires a trusted third party to complete the transaction outside the agreement

bitcoin provides pseudonym transaction, realizes the one-to-one transaction relationship between sender and receiver, and can always record the transactions occurred in the whole network. Bitcoin only provides low-level privacy protection, which is well known in academia. Despite this deficiency, many people still believe in the transfer history recorded by blockchain

based on Nakamoto's achievements, bitshengshi is an encrypted digital currency with the purpose of protecting privacy. We have made a series of improvements on the basis of the concept of bitcoin, resulting in a decentralized cryptocurrency with good anonymity. It supports tamper proof real-time transactions, and has a point-to-point sub network that can provide service reward system for bitsheng network

2. Master node network

the whole node is the server running on the P2P network, so that small nodes can use them to accept the dynamic changes from the whole network. These all nodes need significant traffic and other resources that consume a lot of cost. Therefore, it will be observed that the number of these nodes on the bitcoin network presents a steady downward trend over a period of time, so that the block broadcast time needs an additional 40 seconds. In order to solve this problem, many solutions have been put forward, such as the introction of Microsoft Research's new incentive plan and bitnodes incentive plan

4. Litecoin

litecoin (LTC), released on October 7, 2011, is the most valuable counterfeit coin at present, accounting for about 2% of BTC's market value. The current unit price is US $2.31, with a total currency value of US $38 million

this is also a distributed (decentralized) digital currency. Unlike the sha256 mining algorithm used by bitcoin, LTC adopts scrypt algorithm. Scrypt algorithm uses sha256 as its subroutine, and scrypt itself needs a lot of memory. Each hash is used as the seed of the input, and then it needs a lot of memory to store another pseudo-random sequence to generate the pseudo-random points of the sequence and output the hash value. In the mining of BTC (bitcoin), it is not enough to rely on simple graphics card mining (it takes about ten to dozens of days to dig a BTC with general configuration graphics card). The emergence of various expensive mining machines has raised the threshold for ordinary people to get BTC through mining, while LTC has certain advantages in using PC graphics card mining This passage comes from Zhihu.)

compared with BTC, litecain has made a little improvement in technology. If BTC is gold now, LTC is silver for the time being

the biggest advantage of litecoin is that it can confirm the authenticity faster. The virtual currency is designed and maintained by Charles Lee. Bitcoin transactions need to be verified, and the average verification time is more than 10 minutes. Most transaction websites need 1 hour to verify. The average transaction confirmation time of liteoin is 2.5 minutes. Developers claim that shortening the verification time increases the practicability of virtual currency. The bitcoin mining efficiency of customized machine and AMD GPU is the highest, making it almost unprofitable for miners using CPU mining. Litecain's mining excludes GPUs and custom processors, so it doesn't rely too much on a small number of professional miners

ppcoin

ppcoin (PPC) was released on August 19, 2012, which has improved the original technology of BTC. Use proof of make and add the concept of coin age

ppcoin is a bifurcated project of bitcoin, which aims to achieve energy efficiency and maintain the best performance of the original bitcoin as far as possible. The unit price of ppcoin is US $0.22 and the total currency value is US $4 million

ppcoin does not have a fixed upper limit of money supply, but it does not mean that ppcoin has obvious inflation compared with bitcoin. Bitcoin can be compared to gold. The annual inflation rate of gold is about 1-3%. Although gold has no known upper limit of money supply, we still know that it is a reliable scarce commodity

ppcoin has two types of casting: work certificate and equity certificate. The coinage rate of working proof is affected by Moore's law, which depends on the doubling of our working proof ability. What we all know is that Moore's law will eventually come to an end. By then, the ppcoin of inflation may be close to the gold level. The annual maximum inflation rate of certificate of equity is 1%. At the same time, ppcoin's transaction costs were destroyed to fight inflation. So on the whole, the coin design of ppcoin is still a very low inflation design in the future, which can be comparable with bitcoin<

ppcoin's reward is similar to lottery, which will determine the winning probability according to the number of ppcoin held by miners. Sunny king, one of the founders, said that their design is based on a new concept of long-term energy efficiency

terracoin

terracoin (TRC) was released on October 26, 2012, with a total currency of 42 million. The speed of each block is 2 minutes, slightly faster than LTC. There is not much special in technology, similar to the proction of BTC halved every four years

however, the operation team seems to have a strong business background and may be better than other bitcoins in circulation. The development of virtual currency is getting more and more attention. Now some teams with business background will accelerate the development of virtual currency

namecoin

namecoin is a distributed domain name system based on bitcoin technology. Its principle is the same as bitcoin. The first release date of this open source software is April 18, 2011

namecoin is generated from an original block which is different from bitcoin's main trading block. It uses a new blockchain, which is independent of bitcoin's blockchain. Because it is based on bitcoin, the security, distribution, robustness, encryption and migration of domain names are guaranteed mathematically. You can dig bitcoin and namecoin at the same time

this project was discussed and proposed by bitdns, which is mainly dissatisfied with the defects of DNS. The only top-level domain name of namecoin is. Bit. It costs namecoin to register a. Bit domain name.

5. In short, blockchain is an anti cheating system in digital currency. Just like the anti cheating system in the game, the functions are almost the same
nowadays, many swindlers use the concept of district fast chain to hype, and then pull investment to cheat money. I really don't know what's the use of these people investing in an anti cheating system, which doesn't generate value.

6.

You can see the flow of the transaction, but you can't be sure who the account corresponds to in the real world

a bitcoin account is an address, and an address corresponds to an account. However, there is no need for identity proof to open a bitcoin account. Everyone can open a bitcoin account, and the number of bitcoin accounts can be opened is more than that of sand in the whole world. A person can correspond to multiple accounts, so I don't know which person this address corresponds to, that is, anonymity

7. Bitcoin, Ruitai coin, Laite coin and doggy coin are real digital cryptocurrencies with irreversibility. They are a decentralized distributed network, and it is difficult to trace stolen ones. However, foreign scholars have shown that they can be traced, but they are still in the theoretical stage at present. The last time Ethernet coin was stolen, it was a hard fork solution.

The essence of money is the general equivalent. In the process of the continuous development and evolution of human history, it has gone through the stage of physical money, the stage of substitute money, and then entered the stage of credit money. In primitive society, people exchanged livestock, salt, shells and other hard to get goods as general equivalents

in the long history, the emergence of metal currency makes the economic life achieve unprecedented prosperity. However, e to the inconvenience of carrying metal money, paper money became the mainstream form of money. With the rapid development of modern information technology, e-money has come into our life

if the evolution process from physical money to value symbol paper money is the first qualitative leap in the history of money development, then the evolution process from paper money to electronic money is the second qualitative leap in the history of money development

from the perspective of money form, physical money itself is a commodity in addition to performing monetary functions; Paper money is a symbolic tool of value for commodity exchange and a credit currency; Electronic currency is the proct of highly developed Internet economy and continuous progress of bank payment and settlement technology. It not only has the function of traditional currency, but also can continuously improve digital currency

At the same time, the virtual money market based on electronic information is also booming. By the end of 2014, the number of Internet users in China had reached 632 million, including 517 million registered users in the online game market and 114.48 billion yuan of sales revenue, an actual increase of 37.7% over the previous year

a huge virtual space based on the Internet has been formally formed. As a kind of virtual currency with intrinsic value, convenient online trading behavior, low transaction cost, and service providers' issuance, it emerges as the times require

first of all, from the functional analysis. Virtual currency is a kind of transaction medium in the Internet virtual space, which has the function of value scale, but the value scale of virtual currency is different from that of legal currency

using virtual currency to purchase virtual procts and services can only be within the scope specified and allowed by the issuer of virtual currency (Internet operator), and the size of this scope depends on the number of virtual procts and services. If the virtual procts and services provided by the website are large enough, the scope of virtual currency will be large

the currency value of virtual currency depends on the pricing of virtual currency by issuers. When no currency can communicate between virtual cyberspace and reality, the pricing of procts and services is still based on real RMB. That is to say, when issuers of virtual currency price their own virtual currency, they should first convert the price of virtual currency based on RMB
