Common to blockchain and blackmail virus

1.

In fact, the recent wncry virus is not the first time that blackmail software has become powerful. Not long ago, Android system also appeared a blackmail software, mobile phone encryption after ransom. After the software was checked and killed, it soon made a comeback with an upgraded version. This new version of blackmail software infects files with a random key, and even attackers don't know how to unlock it. Even users pay ransom in vain

we can see that with the continuous development of IT technology, although there are many IT employees, the main employees are mainly concentrated in the fields of mobile platform, cloud and artificial intelligence, and the most popular programming language has graally evolved from C and C + + for underlying operation to managed Java or even go language for modeling. The field of information security is a technology that directly faces the bottom. Fewer and fewer people are engaged in the bottom programming, which means that the number of practitioners of information security is getting smaller and smaller. The direct consequence of this phenomenon is that the backward technology can attack the advanced technology in the network world, which is very similar to the invasion of advanced civilization by the backward barbarians in human society. The recent outbreak of wncry virus may come from North Korea, which also confirms this trend from the side. Some organizations and even countries are not qualified to engage in high-end technology, but the virus they write can spread all over the world. Blackmailer software has further expanded the scope of attack, such as online games, smart cars and wearable devices have a large number of leaks. Reviewing the history of such software can be roughly divided into the following stages

from the current situation, there is no sign of easing the bifurcations of bitcoin, but the emergence of bitcoin ETF and wncry virus has pushed the price of bitcoin to new highs. Personally, I think the short-term rate of bitcoin will probably exceed 20000 RMB. However, considering that there is not all the competition for bifurcations among varieties such as lightcoin, from the perspective of investment, if bitcoin falls again e to the competition for bifurcations, it is actually good for lightcoin. Therefore, if some readers hold a lot of bitcoin and do not want to sell it, You can consider hedging with long Leyte

from the perspective of information security, the bifurcation problem is likely to affect bitcoin's status as a ransom for blackmail virus. The author thinks that the virus accepting Wright coin and ether coin as ransom will be born soon

however, blockchain currencies are more or less troubled by processing speed, and the encryption algorithm is not easy to upgrade. In the long run, the risk is relatively high, and the signs of short-term price manipulation are relatively obvious. If the psychological enrance is not strong, just watch their running track

3. When it comes to the nature of blockchain, several key words are familiar. For example, decentralization, distrust, consensus mechanism, asymmetric encryption, distributed accounting, tamper proof, absolute transparency, openness and so on. At the same time, some teaching posts also list the structure of blockchain, such as data layer, network layer, consensus layer, incentive layer, contract layer and application layer
however, it's easy for people with an eye to see why there is no security layer? In fact, several key features of blockchain have already solved the security problem. First, the blockchain uses asymmetric encryption technology. In fact, encryption and decryption are different keys, namely public key and private key. In short, the public key is open to the public, while the private key is absolutely confidential
secondly, distributed bookkeeping is a way for blockchain to store data. It can also be understood as distributed storage, which is consistent with the concept of decentralization. In the form of ledger, there is no central ledger in the network, and the ledger is stored in each node. Each node is not only independent, but also can act as the central node. Therefore, the central node will not be attacked, leading to the loss of core books or data, and the whole network will not be paralyzed
moreover, tamper proof is the basic feature of blockchain. As long as the chain can not be modified, and can not be deleted. If it needs to be changed, based on the principle of transparency and openness, the whole network and all nodes need to be informed. Therefore, under the democratic mechanism, the possibility of tampering with data at will is very low. Therefore, blockchain technology is applied in various instries, such as finance, payment, traceability, games, etc., such as the network "universe", Tencent's "come together to catch the demon", and Zhongan Huanyu blockchain "Dr dragon hunt" are the safe and high-quality procts under the blockchain technology.

4. Version 3.0 embodies further decentralization and bottom-up thinking. If this meaning and function is concerned, it mainly embodies a four set idea of the whole person, or a person's whole idea, um, some ideas about the private science.

5. This year, virtual currency has entered a relatively bearish stage, and the fluctuation of virtual currency is weaker day by day. For medium and long-term traders, the profit margin of mainstream currency is graally smaller. Personal analysis shows that the fluctuation of bitcoin within the day is no more than $100, which will become a probability event. It also means that it is very difficult to make money by playing virtual currency position contracts in medium and long-term and daily level transactions. Due to the nonstandard nature of the virtual money market, there are still a large number of air currency and pyramid selling currency in the new currency, and some traders are difficult to distinguish them. The new currency is the trend of big risk and big profit
in the first half, the position contract trading mode and the new currency trading mode of the mainstream virtual currency have become the high-risk money making mode. I still think that the upsurge of virtual currency trading in the second half may quickly turn to the derivatives of virtual currency. Virtual currency short-term trading may also be an opportunity to make money in the second half. What is the short-term trading mode of virtual currency? The short-term trading mode of virtual currency is to predict the short-term market trend of a certain currency. For example: the price of bitcoin is at 6666.66. I predict that the market will fall in five minutes, and we will do a fixed amount of trading. When the market is below 6666.65 in five minutes, it will be profitable. The amount of profit is about 80% of the amount of a single investment
because the short-term trading of virtual currency requires less fluctuation in the large range of virtual currency, and the investment amount and transaction capital risk are controllable. So I think the short-term trading mode of virtual currency is a choice of making money in virtual currency trading.

On May 12, the ninth anniversary of the Wenchuan earthquake, bitcoin virus attacks are raging in China

as for how to prevent being attacked, a Microsoft spokesman said that users who run the free antivirus software of the system on Windows computers and enable windows updates can be protected from the virus attack. Windows 10 users can set - windows updates to enable windows updates to install the latest updates. At the same time, they can set - Windows Defender to open the security center

8. It's a lie. I tried it myself

9. The road is one foot high, the devil is one foot high, there are those who spread viruses, there are those who kill viruses, there are hackers, there are those who cure hackers. The blackmail virus that has disturbed us for some time has recently found a solution
what we are interested in is the monetary unit of blackmail, not US dollars, not RMB, but bitcoin
what is bitcoin
what is bitcoin? We have said in previous programs that bitcoin is actually the result of an online game programming invented by Nakamoto in 2009. Because it is a set of programming, the total amount of bitcoin is relatively fixed
how many? 21 million, a bitcoin is about $1803, according to the current valuation, about 40 billion
the underlying technology of bitcoin is blockchain, and blockchain technology is to ensure the authenticity and non tamperability of information by establishing a set of public accounts on the Internet, in which all users in the network jointly keep accounts and check accounts. Its way is to leave a mark. It's hard to change where you come from and where you go
in addition, it has multi centers and is difficult to be controlled by one center, which ensures its value-added and sustainability. This is also an important reason why the blockchain technology now attracts the attention of financial institutions
just because bitcoin has such advantages, this blackmail virus has taken a fancy to bitcoin
What are the problems facing bitcoin
the question is whether bitcoin is a currency or not, which is an issue of concern all over the world
on April 1, the Japanese cabinet signed a document recognizing the legality of bitcoin and other virtual currency payment means, and 260000 stores in Japan will accept bitcoin payment. In addition, the date when the US Securities and Exchange Commission re examined the bitcoin ETF on May 10 is also closely related: if the bitcoin ETF is approved by the US Securities and Exchange Commission for listing, bitcoin's global investment status will enter a new historical stage
before that, China did not recognize bitcoin. In 2013, it specially arranged to crack down on bitcoin, which resulted in the transaction of bitcoin being cut from $1000
therefore, judging from the blackmail virus incident, there is still a large gap and ambiguity in the regulation of bitcoin in China
if you don't recognize the currency attribute of bitcoin, it's difficult to identify this blackmail event as a blackmail event. Because since it's not money, it's not blackmail
in addition, if you approve the currency of bitcoin, our previous definition of bitcoin needs to be revised, which is a new problem brought about by the Internet age
we can't turn a blind eye to it or be an ostrich. We must study its market prospect and application prospect
in a word, laws and regulations should keep up with the development of current technology, appropriately supervise and take precautions, so as to solve the problems brought by bitcoin, including other various electronic currencies in the future.

10. No
through the virus; Blackmail bitcoin
because bitcoin is a virtual currency, there is no issuing institution. It's available all over the world
can't check.
