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.

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

4. The content of blockchain is comprehensive.

5. 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.

6. 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 />

7. 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

8. Come on, I'll tell you. Your game installed a mod, the mod function is to increase the emergence of him, his full name I do not remember. He is a kind of hostile creature like zombies and skeletons, but he is very smart. It's all about increasing the playability of the game. It's not surprising. It really makes your hair stand on end. You can check "my world him". Don't be afraid, the general version has no him for a long time, this is just a plug-in. What you see is him

9. Blockchain has been applied in many fields, such as government affairs, Internet of things, pension and so on. For example, bat, a well-known big company, is also studying and applying blockchain technology

the current market situation and development of blockchain:

currently, blockchain applications in the market are mainly issuing "token", realizing "integral management" and pet games, with relatively single functions and few data of blockchain related apps, More are financial apps
