Smart contract swindles virtual currency

1.

Some time ago, a picture of Chinese aunts appearing on the scene of the blockchain conference became popular on the Internet. For a while, it caused a heated discussion. Netizens said one after another: "aunts have been targeted by the blockchain." In fact, since a few years ago, when the concept of blockchain came out, there have been some illegal elements carrying out pyramid selling activities in the name of blockchain, which has become one of the latest varieties of pyramid selling. In fact, with the development of blockchain, all kinds of virtual currencies emerge as the times require. Most of them are scams. In the name of "virtual currency" and "blockchain", swindlers carry out scams. This is mainly to make use of the psychology that investors do not understand virtual currency and blockchain, but want to catch up with the upsurge of virtual currency investment. This kind of scam seems complicated, but it is also very simple. However, once it is cheated, it is difficult to recover the investment

in a word, blockchain technology is not a fraud, but is used by swindlers to cheat investors by using information asymmetry

5. It is said that there are a total of 150000 participants in the country. I don't know how many of them have earned. Most of them have lost money. Many of them are old people! I'm from Xi'an city. The City Express reported a few days ago. I heard that several four-star directors were arrested. Because they used the mode of pyramid selling, it's more complicated. The public security organ has no way to file a case. Now they are released again. Looking at the swindlers all day with the money cheats to eat, drink and play natural and unrestrained, we are angry and anxious, Leng is to take them no way! No one cares about the country! Think about the future to cheat well, cheat is the ability! I sincerely hope that the relevant departments will step in as soon as possible. Otherwise, the longer the delay, the less hope of getting the money back!

6. The following three points are briefly analyzed:
(1) blockchain
since 2013, virtual currency has graally attracted people's attention, and even set off a wave of upsurge of virtual currency. However, many people do not know that the real value is the background technology of virtual currency - blockchain. Virtual currency is only one of the most original applications of blockchain technology, and its rise has brought about a lot of problems, There is also an inevitable reason, that is, blockchain technology endows them with the core characteristics of fairness, impartiality and openness. The practical application of virtual currency is very few, and there is no real value support. Even some virtual currencies recognized by many countries are occasionally traded, not to mention applied. Most of them are just doing price speculation, leading to the price of virtual currency fluctuating, Extremely unstable, because of its price instability, it can not become a real currency. It is precisely because blockchain has the technology gene of fairness, impartiality and openness that almost all banks and financial institutions around the world are studying and using blockchain technology, including UBS, Citigroup, the Federal Reserve, the Bank of England, the Central Bank of China and so on. Why is blockchain so popular? Because it fundamentally enhances the banking instry, supply chain, property management and other trading networks, It is considered to be the core technology with the most potential to trigger the fifth round of disruptive revolution after steam engine, power information and Internet technology 2) (2) smart contract
these advanced applications of blockchain are called "smart contract". Smart contract is the core application that can really bring revolutionary progress. You will find that smart contract is becoming the mainstream of the market, and we will soon enter the era of smart contract
(3) quantum technology
in such a developed world of Internet, how to ensure your information privacy, how to ensure the security of your online banking password, chat records, virtual currency and everything that needs a password, all these are e to the public key and private key encryption algorithm widely used in the current Internet. If this algorithm is decrypted by the current computer, It's almost impossible to complete the task, and it often takes tens of thousands of years or even longer to decrypt. However, within 5-10 years, quantum computers will appear. When quantum computers are used to decrypt, these passwords will only take a few seconds to be decrypted. Our bank funds, social information, and virtual currency will not be safe. Therefore, we can't use quantum computers to decrypt, At present, the research against quantum decryption has become a global hot spot, including the pqcrypto and safecrypto research program supported by the European Union, the crest crypto math research program of Japan, and so on. Major enterprises have also expressed their views, such as Intel's quantum chip, Google's quantum encryption, and quantum communication technologies actively encouraged by governments, So quantum technology is the best future technology. It is not only a spear, but also a shield. It can subvert our current security system and bring us super efficient computing solutions.

It means that compared with the traditional centralized exchange, the tokenlon brand of imtoken is no longer a centralized platform. The currency exchange of users is based on smart contracts, such as flash exchange based on kyber protocol and point-to-point currency exchange based on the protocol of 0x

a P2P form of digital code, its creative idea comes from bitcoin. Like bitcoin, atomic coin does not rely on a specific currency institution. It is generated by a large number of calculations based on a specific algorithm. Atomic coin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions

a protocol is a technical implementation, on which a contractual commitment is realized or recorded. Which agreement to choose depends on many factors, the most important of which is the nature of the assets being traded ring the performance of the contract

extended data:

Keynes divided money demand into three motivations: transactional motivation; transaction motivation; transaction motivation; Preventive demand motivation; Speculative demand motivation. Therefore, there are two kinds of money demand: consumption money demand and speculative money demand. The form of demand function is: MD / P = L1 (y) + L2 (I)

the formula describes that L1 is the consumption money demand (including transactional and preventive motivation) is the positive relationship between the real income, L2 is the speculative money demand and the interest rate is the reverse relationship

after the circulation and use of network currency, the currency turnover period will be greatly shortened because the conversion cost of different currencies is almost zero. On the one hand, the proportion of money people hold for trading and prevention motives will decrease

8. This is absolutely pyramid selling. It's very popular in Xianyang, Xi'an. It deceives a lot of people. My mother was cheated. I know a few upper class swindlers. They are always called Yang Yonggang and Li Lintao

9. In the narrow sense of blockchain technology, blockchain is a kind of chained data structure that combines data blocks in chronological order in a sequential way,
and is a distributed account book that can not be tampered with and forged by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing method, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
NMC coin, also known as domain name coin, is a distributed domain name system based on bitcoin technology, which has the characteristics of security and non censorship< However, e to the relative lack of supervision, digital currency is easy to be pulled up or sold, so it may become rich overnight or lose all principal overnight. This is the general nature of digital currency, not just NMC currency
the connection is that CNM is developed based on blockchain technology.
