What are the risks of 360 blockchain

1.

Although driven by the influx of capital and talents, the blockchain instry ushered in rapid development, but as an emerging instry, the frequent warning of its security vulnerabilities caused people to worry about the risk of blockchain

Yu Kequn, director of the national information technology security research center, pointed out that the emergence of blockchain has brought people a lot of expectations for privacy exposure, data leakage, information tampering, network fraud and other issues. However, there are still many challenges in the security of blockchain

Li Bin, assistant director of China Information Security Evaluation Center, analyzed that the current blockchain is divided into three types: public chain, private chain and alliance chain. No matter which type, it faces security challenges in algorithm, protocol, use, time limit and system. What is particularly critical is that the current blockchain is still facing 51% attack problem, that is, nodes can successfully tamper and forge blockchain data by mastering more than 51% of the network examples

it is worth noting that in addition to external malicious attack risk, blockchain also faces the threat of its endogenous risk. Yu Kequn reminded that how to build a complete security application system around the equipment, data, application, encryption, authentication and authority of the application system of the whole blockchain is an important problem that all parties must face

Wu Jia also analyzed that as an emerging instry, employees in the blockchain instry are lack of safety awareness, which leads to the low safety factor of the software and hardware related to the blockchain and a large number of security loopholes. In addition, there are many ecological links in the whole blockchain. In contrast, the strength of the relevant security employees is scattered and it is difficult to form a joint force to solve the problem. A systematic solution is needed to meet the above challenges

2. There must be risks, and they are high risks, because high returns are always bound with high risks. You are a little rookie who doesn't know anything. Can you make money like other people's old birds? If you are just interested in the coin circle, I suggest you don't be reluctant to spend a small amount of money to add a pay circle of the coin circle. For example, the group of Li Xiaolai, the big money in the coin circle, once cost as much as 5 million yuan. There are also some old cats and baoerye groups, but they are too far away from us ordinary people. But if you have a lot of money, it's a good deal. If it's only tens of thousands, it's suggested to add some groups with high cost performance, such as the payment group of fire chain blockchain, Zhongshen blockchain club, which are reliable, and there is a free trial period.

3. Forget the private key, the mnemonic note lost... This is the most basic. When it comes to the essence of investment, it is the investment risk caused by the fluctuation of currency price. GRE global risk trading all specialized insurance can be bought to avoid the risk of digital money market.

4. How much risk you can take and how much you will get in return. Just like in troubled times, people who rise up may fall to the ground or become the next emperor. The question is, do you dare@ Block chain God Tucao: make complaints about investment risks correctly.

5. Yes, blockchain is a high-risk project.

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

7. Most lovers go to Zhuang by car first. What do you think Fengshen has at present? Many students communicate with each other to create a space project. There are all kinds of absolute landscape risks. Therefore, the doubles project has been closed to the county. There are all kinds of creation competitions. The youth project is a landscape project. There are all kinds of illusions of College Students' competitions. It has been sent to the East landscape risk.

8. Pishon platform is OK. It is the world's first superconcting mechanism. It's decentralized, smart contract, chain execution, full open data, fair, just, open and transparent. It's the world's first mechanism based on wave field development.

9. In fact, this kind of platform has certain risks. The Pishon platform is actually OK. Smart contract, chain execution, data transparency, decentralized wallet participation, is a real decentralized platform without much risk.
