The most fundamental characteristics of blockchain

1.

With the increasing demand in the market, our business has been in short supply, so our technicians will find more procts for us to use. blockchain is one of the most prominent and essential features of blockchain:

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

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

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 can be transferred anonymously

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system

2. The biggest feature of jinwowo network technology analysis blockchain is decentralization
at present, the traditional database is centralized recording and storage. Even for remote disaster recovery and cloud storage, it only changes the storage location from one place to multiple places, from local to cloud. If there is a problem with the central server, the disaster recovery database will stop updating data; The blockchain database is distributed record, distributed storage and distributed propagation. Each information is transmitted by a single node to all other nodes in the whole network. Each node is responsible for data recording and storage. No centralized or third-party organization is responsible for management. If one node has problems, other nodes will continue to update and store data, Through the way of decentralization, the stable operation of the system is maintained, and the information is complete and reliable.

3. Decentralized
e to the use of Distributed Accounting and storage, there is no centralized hardware or management organization, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system
openness
the system is open, in addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all, and anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
autonomy
blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work
information cannot be tampered with
once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high<
anonymity
since the exchange between nodes follows a fixed algorithm, their data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective by themselves), so the counterparties do not need to trust themselves by disclosing their identities, which is very helpful for credit accumulation

According to reports, blockchain has the advantages of decentralization, distrust and tamper proof

compared with the Internet, the blockchain network conceived by Cosmos not only realizes information interaction, but also realizes the transmission of asset value. Through the IBC cross chain protocol, the token can be transferred across the chain between the blockchains based on Cosmos' tendermint core. For the public chains based on POW consensus mechanism like Ethereum, pegged zone can be used to bridge

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

8. The combat effectiveness of lol hero League is composed of (1) three parts: ranking, winning rate and fighting times<
specifically for
first, qualifying plus
for all players participating in qualifying, the game will be initialized to 1200 points by default, which can be divided into three types: team 3v3, team 5v5, single 5v5
this score is called rank score (or ELO), and the score lower than 1200 points will not be displayed, which can be found in the game
the ELO plus component in combat effectiveness is converted on the basis of the official ELO score of the game. The detailed rules are as follows:
(1) if a player has never played in any qualifying match, 1100 points will be counted
(2) take the highest one from the three rank scores to calculate
(3) ELO additive component = ELO * (1 + (elo-1000) / 2000) ^ 1.4
briefly, if the ELO score is higher, the ELO additive component is also higher, showing an exponential growth. The ELO score of a player with 1300 points is 1580, while that of a player with 2000 points is 3528< Second, the winning rate plus the composition
the winning rate is the number of winning games / total games, which is represented by winratio below< The detailed rules are as follows:
(1) because more than 95% of the players often play match games, the winning rate is only the winning rate of match games; Unless this person doesn't play a match, it's only qualifying
(2) if the winning rate exceeds 70%, it will be only 70%; It is extremely rare to win more than 70% of matches in more than 100 matches
(3) if the winning rate is more than 50%, the formula of winning rate plus component is 750 + 100 * (winratio-50) ^ 0.7; If the winning rate is less than 50%, the formula of winning rate plus composition is 750 - (100 * (50 - $winratio) ^ 0.7). (4) based on the third step above, adjust the winning field:
- if the winning field is less than 20, the winning rate plus component is winratioscore * winning field / 20
- if the winning field is greater than 50, 100, 150, 300, 500, then multiply winratioscore by 1.1, 1.15, 1.2, 1.25, 1.3
(5) on the basis of the fourth step above, carry out ELO condition: multiply by 0.65 * (ELO / 1000) ^ 1.1, if 0.65 * (ELO / 1000) ^ 1.1 & lt; 1, the original score remains unchanged
the highest score of this item is about 3000; If a person's winning rate is less than 35%, he may only get 0 point
Third, the more winning games, the more points. The score of this game will increase steadily, mainly reflecting whether a player is old enough
accounting calculates the winning field plus component of the following two modes, and takes the highest one
(1) match match winning game plus components: each win, plus 2 points, up to 3000 points
(2) the winning field plus component of qualifying: calculate the ELO Net Score (the highest of the three types), with a maximum of 4000 points
the formula for the difference points is (elo-1000) * 1.5 + the difference points * 15.
