The following features do not belong to blockchain

1. blockchain technology is the underlying technology derived from big data, like a database recording all relevant important data. According to the research of jinwowo group, the characteristics of blockchain technology are as follows:
1-decentralization
2-transparency
3 - openness
4-autonomy
5 - information cannot be tampered with
6 - anonymity.

2. It is understood that compared with the traditional centralized scheme, blockchain technology mainly has the following three characteristics:

the core idea of blockchain is decentralization

in the blockchain system, the rights and obligations of any node are equal, and all nodes have the ability to vote with computing power, Thus, the result recognized by more than half of the nodes is guaranteed. Even under serious hacker attacks, as long as the number of nodes controlled by hackers does not exceed half of the total number of nodes in the world, the system can still operate normally and the data will not be tampered with

block chain's biggest subversive nature is the establishment of credit

theoretically, block chain technology can make WeChat payment and Alipay no longer exist value. The economist makes an image metaphor for blockchain: in short, it is "a machine for creating trust". Blockchain enables people to cooperate with each other in the case of mutual distrust and no neutral central institution. The fight against counterfeit money and financial fraud will not be needed in the future

the collective maintenance of blockchain can rece the cost

under the centralized network system, the maintenance and operation of the system depend on the operation and maintenance of platforms such as data center, and the cost cannot be omitted. Anyone can participate in the nodes of the blockchain. Each node can verify the correctness of the results of other nodes' records while participating in the records, which improves the maintenance efficiency and reces the cost

in a word, blockchain touches money, trust and power, which are the fundamental basis for human survival.

3. Blockchain has the following characteristics:
decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain

openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

A: the basic characteristics of blockchain

I. decentralization
blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage

Second, openness

the foundation of blockchain technology is open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

Third, independence

based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

Four, safety

as long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily controlled and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes

5. Anonymity

unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information transmission can be anonymous

Pyramid selling is harmful to family, society, indivial mind and social stability

Deng Wanhong, deputy director of Shenyang Public Security Bureau, said on the 18th that Shenyang police have successfully cracked a major pyramid selling case involving 25 provinces, autonomous regions and cities through continuous efforts. Up to now, the police suspect 24 suspects in criminal detention, and seized 364 million yuan in cash. On September 15 this year, a clue to the implementation of illegal pyramid selling activities entered the sight of Shenyang police. According to the preliminary investigation of Shenyang Public Security Bureau, the gang involved a large number of people. In September and October this year alone, it developed nearly 100000 people, involving 25 provinces, autonomous regions and cities such as Liaoning, Beijing and Tianjin. According to the preliminary statistics, the amount involved in the case reached 600 million yuan. The gang is eligible for membership by paying a membership fee of 3900 yuan per person. At that time, it will get an annual income of no less than 150000 yuan. At the same time, each member of the development of a new member, you can get a bonus of several hundred yuan

In short, the existence of MLM organizations not only threatens families and indivials, but also affects social stability

There are four kinds of minerals in the devil's land:

1. iron ore: can be used for divorce; iron ore: can be used for divorce; iron ore: can be used for divorce 10 pieces of unlimited quality + 20W gold coins are required

2. Gold Mine: it can be used to repair equipment with loss degree of 0 ＜ required quality of more than 5 ＞

3. silver ore and copper ore: these two ores have no major use, but some special tasks can still be used

7. First of all, it can only be found in the activity time
digging things is random probability. If a point can't be g all the time, you can only try another point. There's no trick to take advantage of
