Blockchain server penetration

1. It can be, but it is usually g by special mining machine, and the mining efficiency of CPU is far less than that of GPU

2. To be exact, blockchain and traditional server cannot be compared together, because blockchain is a technical model, while server is a kind of hardware resource
but if we have to compare them, we can first see the differences or connections between the two characteristics
the traditional server is centralized
take a look at the figure below, it is a typical centralized network, the most central is the server, the others are clients, the server is responsible for providing services to all clients, and the client obtains services from the server, such as downloading files.

On June 8, 360 exposed the high-risk vulnerability of EOS, which caused a lot of hot discussion among networks. In the early morning of June 2, Beijing time, EOS officially acknowledged to the 360 security team and offered a reward of US $30000, strongly calling on the security community to work together to ensure the continuous improvement of EOS software security

360 exposed EOS vulnerability, if exploited, can control every node and every server in the EOS network, not only take over the virtual currency, various transactions and applications in the network, but also take over all participating servers in the node. It can be said that if someone makes a malicious smart contract, all the digital currencies in it can be taken away directly

the attack of EOS vulnerability can spread among multiple nodes and super nodes at the speed of seconds. The continuous propagation from the control node to the generation of new blocks is a continuous and chain explosion action. It is likely to take over all nodes and complete the operation in 20 seconds

imagine that when the attacker has obtained the supreme authority in the entire EOS network, it is equivalent to mieba putting together all six cosmic protoliths, and can change rapidly in the universe and do whatever he likes

4. bitcoin.cz's first large mine, slush's own Chinese course! The content is very detailed. It's a very good choice for those who don't understand foreign languages or bitcoin~

5. Hello, to be exact, blockchain is a technology model, while server is a kind of hardware resource. There will be a combination of the two. For example, the combination of storage type server and blockchain improves information security
with the development of the Internet, data are stored in the storage server, the security of data can not help everyone's worry. Blockchain technology, using cryptography to ensure the security of data transmission and access, in the process of data extraction, can realize the centralized use of unstructured data required by various research, so as to make the storage server data secure
the 10th party provides IT hardware solutions for enterprises such as server leasing and sales, and has a wide range of cooperation instries, including Internet, blockchain, scientific research institutions, rendering design, intelligent manufacturing, etc.

6. It is said that they made the fresh sweet scented osmanthus by themselves. They have been taught patent research for more than ten years and published papers. It is estimated that other families do not have them...

then it seems that the proct does have the flavor of sweet scented osmanthus, but it is lighter, the color is still transparent, there is no yellow or orange in imagination, and there is no petal, high technology, Don't you understand?

7. (1) Some places can, but belong to a few, not as good as jewelry stores, some restaurants. But most shopping malls or chain stores can use UnionPay. But it's better to exchange some Hong Kong dollars before you go to Hong Kong, because small things still need to be paid in cash, and considering that if LZ ~ you two want to use octopus, you need to use cash 150 to buy cards

(2) everything is available at Sai Yeung Choi Street and Nathan Road in Mong Kok (two parallel roads). The former is the most concentrated place of digital procts in Hong Kong, with several Fengze, Broadway, Zhongyuan and Suning lasers. For cosmetics and skin care procts, there are several branches of Sasa, Zhuoyue, angel and colormix, as well as H2O and FANCL. Daily necessities to Nathan Road, Watsons and Wanning. There are also Huikang or Baijia supermarkets near xiyangcai street< (3) there are many budget hotels in Yau Tsim Mong (Yau Ma Tei, Tsim Sha Tsui and Mong Kok). Small as the sparrow is, it has all the internal organs. We can't expect a big room, but the facilities and sanitation are good. The average price is about HK $300-350. You can search the red tea house and haowangjiao Hotel on the Internet<

(I) Guangdong East railway station takes harmony (75 yuan or 95 yuan) to Luohu railway station, next to Luohu port
(II) after entering Hong Kong, take the east rail to Mong Kok East Station. It's about 40 minutes' drive. The one-way fare is 33 yuan, while the octopus fare is 31.3 yuan. When you get to Mong Kok East Station, go west at exit b and walk for 15 minutes to Sai Yeung Choi Street.

8. This scoring trading platform has servers, wallets,
blockchain,
and the price is not expensive. Hundreds or thousands of yuan are OK

9. If it is the proof of workload, it can be modified, but it needs to invest a lot of money. For example, if you want to change the block data of bitcoin (such as transferring all bitcoin to your wallet, etc.), it needs to account for 51% of the total network computing power. But with so many miners digging, it is basically impossible to account for 51% of the total network computing power.

10. The result of these two attacks is that the other party's system is out of service or crashed e to information overload. But DoS attack is a single server attack, while DDoS attack is distributed multiple servers attack, the success of the attack is higher. The application of blockchain technology should be more and more, so it is necessary to understand the knowledge of blockchain. It is recommended that you go to the official website of Xuanling technology. This website has many popular science and application posts of blockchain technology, which should be of great help to blockchain learning.
