Recently, Vulcan team of 360 company found a series of high-risk security vulnerabilities in EOS, a blockchain platform. It is verified that some of the vulnerabilities can remotely execute arbitrary code on EOS nodes, that is, they can directly control and take over all nodes running on EOS through remote attacks

In the early morning of May 29, 360 reported this kind of vulnerability to EOS official for the first time, and assisted it to repair the security risks. The person in charge of the EOS network said that the EOS network will not be officially launched until these problems are fixed

EOS super node attack: the virtual currency transaction is completely controlled

in the attack, the attacker will construct and publish a smart contract containing malicious code, and the EOS super node will execute the malicious contract and trigger the security vulnerability. The attacker then uses the super node to pack the malicious contract into a new block, resulting in the remote control of all nodes in the network (alternative super node, exchange recharge withdrawal node, digital currency wallet server node, etc.)

because the system of the node has been completely controlled, the attacker can "do whatever he wants", such as stealing the key of the EOS super node and controlling the virtual currency transaction of the EOS network; Obtain other financial and privacy data in the participating node system of EOS network, such as digital currency in the exchange, user key stored in the wallet, key user information and privacy data, etc

What's more, an attacker can turn a node in the EOS network into a member of a botnet, launch a network attack, or become a free "miner" to extract other digital currency

3. The content of blockchain is comprehensive.

4. Classification and application of blockchain:
1. According to different scenarios, design systems and attribution, blockchain is generally divided into three categories: public chain (public service), private chain (focusing on the application of an enterprise or instry) and alliance chain (generally belonging to an instry or a supply chain)
2. It is basically divided into three kinds of applications:
blockchain applications of well-known enterprises: (Netease blockchain cat (game), thunderbolt chain customer, storm's cool broadcast cloud (BFC points), Renren's social rrcoin, Meitu's e-commerce + blockchain, 360's router, cheetah and other well-known enterprises)
start up companies based on blockchain (Ethernet wallet, Babbitt, fire coin)<
social public applications (the bank has set up a research and development laboratory)
current market situation and development of blockchain:
currently, blockchain applications in the market still focus on issuing "token", realizing "point management"
, pet games, etc., with relatively single functions, and the data of blockchain related apps is even less, and more of them are financial apps.

5. It takes 57 days for rx470 and 100 days for 1070. I hope you can get rid of this idea. Now the appreciation of the virtual coin country is choking, so we need to be cautious< br />

6. The maximum computing power is 68th / s. Shenma M20S
because the mining machine has a service life, in order to ensure that the computing power does not decline, it only provides a 2-year lease term

7. Blockchain 360 blockchain is a fast-moving technology, which fundamentally changes finance, supply chain, medicine, insurance, law and commerce. Join the host, Bryant Nielson, and he just

8. Look at the balance sheet, look at the profit, etc. first go to the company to look at its report. Look at the profit from its sales revenue.
for example, what is the proportion of profit. From the size of gross profit, we can know how a company's buyer is.
if the proportion of gross profit and sales is large, it means that its purchase is cheap,
or focus on short-term profits. From the ratio of working capital and current liabilities, we can see the company's ability to repay others
if it's too low, it can explain the company's management efficiency is not high. If it's too high, it also shows that the company is not good at investment.
in other aspects, you can look at the company's managers to understand their background, evaluate their ability, and whether they are suitable for the company. Or from the past performance, you can look at the company's loans. If there are too many, there will be risks, or lack of confidence. Dividing the net profit by the sales volume, we can know the consumption management of the company in other aspects, such as water and electricity, office supplies, etc. if the result is relatively high, it means that the company is economical and orderly. If it is relatively low, it means that the efficiency of the company is not high, It shows that the direction of the company is right
