Blockchain is the hot spot at present. Taking advantage of this heat, blockchain companies and block platforms are pouring out from all directions. Blockchain talents instantly become the biggest recruitment outlet, with an average salary of 25000 yuan. The demand for talents is still in short supply
on the recruitment website, Shanghai, Beijing and Hangzhou have a large demand for talents, and the conditions and annual salary given by the companies that recruit talents related to "blockchain" are about 500000 to 800000 yuan, and even millions of annual salary. However, the current recruitment demand is still biased towards technical talents, such as blockchain system engineer, blockchain technical director and blockchain architect
enterprises recruit blockchain talents one after another, but the demand for talents is still insufficient. According to the talent trend report of 2018 peak season, in the first two months of 2018, the recruitment demand for blockchain related talents has reached 9.7 times of the same period in 2017. Meanwhile, the number of companies publishing blockchain related positions has increased by 4.6 times and the talent supply has increased by 235% year on year, but the stock is far lower than the actual demand
The explosive blockchain gives people unlimited fantasy. When many people think about the benefits of blockchain, one of its problems has aroused people's concern, that is, security. Some time ago, 360 discovered a high-risk vulnerability in the blockchain, which can control all the nodes on the EOS. We all know that 51% of the nodes in the blockchain can tamper with the data, let alone 100%. Let's see what's going on
On May 29, 360 Vulcan team announced that it had discovered a series of high-risk security vulnerabilities of EOS 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. For more details, please clickRecently, 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

It was reported on May 29 that 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
the hidden dangers of blockchain network security need to be paid attention to
EOS is a new blockchain platform known as "blockchain 3.0". At present, its token market value is as high as 69 billion yuan, ranking fifth in the global market value
in the blockchain network and digital currency system, nodes, wallets, mines, exchanges and smart contracts all have many attack surfaces. 360 security team has found and exposed several serious security vulnerabilities for digital currency nodes, wallets, mines and smart contracts
this time, the 360 security team found a series of new security vulnerabilities in the smart contract virtual machine of EOS platform, which is a series of unprecedented security risks. No security researchers have found such problems before. This type of security problem not only affects EOS, but also may affect other types of blockchain platforms and virtual currency applications
360 expressed the hope that through the discovery and disclosure of this vulnerability, the blockchain instry and security peers will pay more attention to the security of such issues, and jointly enhance the security of the blockchain network

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
