Blue Shield bitcoin
It's not reliable, but it's not a hoax
fire coin is a bitcoin trading platform. On September 15, 2017, fire coin announced that registration and RMB recharge services will be suspended from now on, and all users will be informed to stop trading before September 30. At the same time, all transactions of digital assets against RMB will be graally stopped before October 31
although each platform stated in the public statement that the online projects had been strictly reviewed, in fact, many projects with extremely poor reputation also landed on the trading platforms including coin security and fire coin. Only for the purpose of making money, lack of supervision, take it all. This kind of exchange has been popular for a while. Should regulators take action
as we all know, bitcoin can realize point-to-point value transmission. In addition to bitcoin blockchain, there are many other blockchains, such as Ethereum blockchain. Therefore, we should distinguish the concepts of bitcoin, bitcoin blockchain, blockchain and blockchain technology
blockchain, which is first accompanied by the emergence of digital currency, has recently been widely discussed in the instry for its subversive impact on the existing financial field, and is known as a new round of change after the Internet technology revolution. As a distributed general ledger, this technology will first break out a huge force of change in the financial field: clearing, settlement, remittance, payment, value transmission, innovation and inclusive of the whole financial network, including all income groups, connecting regions and people separated by physical borders, and reshaping the whole economy and society
because blockchain is an open, transparent, traceable and tamper proof distributed general ledger system, blockchain technology can effectively rece the error rate of payment, clearing and settlement steps, and monitor the inflow and outflow of funds in each step, which is an effective means to promote the establishment of an honest society. Therefore, if the regulatory authorities can effectively use this technology, it will help to control the asset status and possible risks of the financial instry
China's blockchain enterprises continue to emerge
since 2015, China's attention and Research on blockchain technology has graally expanded

Prior to that, the people's Bank of China also held a seminar on digital currency. In addition to the central bank, Zhejiang Province, Beijing and other relevant government departments also expressed their support for blockchain application research last year
from the perspective of enterprises, Wanxiang Group has established a blockchain laboratory, and many blockchain innovation and entrepreneurship enterprises continue to emerge< In addition, a number of instry alliances are being established. In December 2015, blockchain research alliance and blockchain Application Research Center were established; In February 2016, Zhongguancun blockchain instry alliance was established; In April, China ledger officially announced its establishment in Beijing<

blockchain is like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry.

According to the report, this round of virus can be compared with the aggressiveness of the blackmail virus sweeping the world in May
Juniper Networks published a blog to analyze the attack. It thinks that the harm of this attack may be more serious than blackmail attack, because the attack makes the computer unable to respond and restartthe researchers also said that this attack may have borrowed malicious code from previous blackmail attacks (such as Petya and goldeneye attacks)
since the attack last month, the government, security companies and instry groups have suggested that enterprises and consumers upgrade their systems and install new Microsoft patches for computers to defuse the threat
The U.S. Homeland Security Agency said it closely monitored the attacks and cooperated with other countries. Homeland Security advises victims not to pay ransom, because even if they do, they may not be able to resume the visitshadowbrokers disclosed the tools of eternalblue and other hackers on the Internet.

According to CCTV, a new round of super computer virus is spreading rapidly in many European countries, including Russia, Britain, Ukraine, etc. Airports, banks and large enterprises were reported to be infected with the virus. According to the report, this round of virus can be compared with the aggressiveness of the blackmail virus sweeping the world in May
the impact may be more serious
blackmail software invades the windows computer, encrypts the hard disk, rewrites the file, and then requires the victim to pay $300 in bitcoin to re-enter the computer. According to the information released by blockchain.info, more than 30 victims have made payments and remitted money to bitcoin accounts related to the attack

we learned from a security manufacturer that they are studying the code of the virus to check whether it belongs to worm
Since May 12, the global network has been attacked by a mysterious blackmail virus, which has infected more than 300000 computers in at least 150 countries and regions, triggering a global Internet disaster. Once the victim's computer is attacked, it will be locked by hackers and prompted to pay the equivalent of $300 (about 2069 yuan) of bitcoin to unlock
a large number of organizations around the world have been attacked by it. In some hospitals that have been attacked, operations have been cancelled, which could lead to innocent deaths. The computer system of Indonesia's largest cancer hospital has been invaded by "blackmail virus". It is unable to access the medical records of patients on the Internet, so it has to be handled manually. As a result, the treatment time has been greatly extended, and the waiting room is full of patients. The hospital later said that 70% to 80% of the computers returned to normal. On the railway side, the German railway company said that e to the virus attack, the train frequency display and ticket vending machine could not operate, and the company sent more personnel to busy stations to provide information to passengers. In addition, after Renault's computer system was recruited, several of its factories stopped proction to prevent the expansion of the scope of the attack. The virus wave has also spread to the energy sector. The payment system of some gas stations of PetroChina was once recruited. People can't swipe cards or use the Internet to pay for oil, but can only pay in cash
Another beneficiary of
is, of course, bitcoin. The ransom that the blackmail virus requires users to pay is bitcoin. Bitcoin has the characteristics of decentralization. It does not belong to any country, organization or indivial. It is anonymous and can be converted into multinational currencies. Because bitcoin has these characteristics, its value does not depend on a country or organization, but more on speculation. If bitcoin was only known by a small number of people before that, the eternal blue virus made hundreds of thousands of people know about bitcoin and made a very beautiful advertisement for bitcoin
in addition, the blackmail software named "want to cry" also makes the network security sector of A-share market "laugh". On May 15, network security concept stocks broke out collectively. By the end of the day, 10 stocks such as Lann, tuoershi, renzixing and qimingxingchen were trading at the limit, with the plate leading the two markets with a 3.13% increase. Huachuang Securities pointed out that after the previous "panda burning incense" virus and prism door incident, the network security sector index rose by more than 70%
the analysis also points out that the "network security law" will be implemented soon from June 1. On the one hand, the legislation in the field of information security and network security shows the urgent need for the state to protect the legitimate rights and interests of citizens in cyberspace and maintain the tranquility of cyberspace. On the other hand, it also shows that the state will actively crack down on crimes in the aspect of network security Internal network security audit and network security infrastructure to strengthen management. From the perspective of IT investment, the blackmail virus outbreak is expected to directly promote all levels to pay more attention to information security, especially in key instries such as ecation instry, government departments and large central enterprise groups. The investment in information security, network security and later operation and maintenance is expected to continue to increase
