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.

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. 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

4. If we simplify the description of the operation process of the traditional notarial certificate, it should be like this: the parties apply for notarization - the notary office evaluates the application - confirms the authenticity and legality of the application items - makes, issues and delivers the notarial certificate. The running process of blockchain public certificate is similar. However, the operation mechanism behind the same operation process is not the same. The reason why the public certificate of blockchain is regarded as the Manifesto of the new environment of notarization is that it has made a subversive change to the traditional notarization certificate in the operation mechanism
01, the core operation mechanism of blockchain public certificate
the operation mechanism of blockchain public certificate is composed of two moles: "Notarization management" and "intelligent assistance". After the applicant submits the application, the blockchain notarization system relies on AI technology to audit the identity and information of the applicant. At the same time, the system will review the content of notarial evidence, and then issue a notarial certificate, at the same time on the chain filing. At the same time, the public certificate of blockchain has been formally formed, which immediately meets the online verification needs of users
the core of the operation mechanism of the notarial certificate of the blockchain lies in the application of the blockchain technology. No matter audio, video, photo or document, as long as it is stamped with a time stamp and then put on the chain, it can become an unchangeable and indestructible evidence document
the second important support in the operation mechanism of the notarial certificate of blockchain is the application of artificial intelligence. The application of this technology greatly saves the applicant's application and waiting time, and also greatly improves the speed and accuracy of the notarial office's document confirmation, eliminating the time delay of manual confirmation and possible operational errors<
02, analysis of the characteristics of the operation mechanism of the notarial certificate of blockchain
through the detailed disassembly of the operation mechanism diagram of the notarial certificate of blockchain, it is not difficult to find that compared with the operation mechanism of the traditional notarial certificate, the operation mechanism of the notarial certificate of blockchain has many noteworthy characteristics
the first is synchronization. In the process of generating the public certificate of blockchain, the actions of the applicant and the notary organization are almost synchronous, and the applicant's application and the notary organization's examination, certificate preparation and certificate issuance are almost synchronous. However, in traditional notarization, there is a time interval between the actions of all parties, which is prone to usurpation. Moreover, e to manual operation, a large amount of time cost will be generated, It further causes the delay of the process. The actions of all parties of blockchain notarization are synchronized online, and the action traces and data are generated instantaneously, thus recing the possibility of tampering and ensuring the authenticity and judicial effect of data files
the second is interactivity. In the process of generating the public certificate of blockchain, the actions of the applicant and the notarization institution are interactive - the applicant submits the application, the notarization institution's artificial intelligence audit, the certificate preparation, the certificate issuance, the data archiving, and the applicant's query are carried out alternately. Different from the traditional notarization, the applicant is more in a passive waiting state after submitting the application, which reces the participation of the applicant
dynamic again. In the process of generating the public certificate of blockchain, the evidence file is a dynamic generation process. The process of applying for the notarial certificate is the process of generating the notarial evidence, and this process itself is a part of the notarial certificate. The traditional notarization is that before the notarization, the evidence documents have been basically finalized. What the notary office does is just a process of confirmation and seal, and the dispute prevention function of notarization is weakened
it is precisely because the operation mechanism of the block chain notarial certificate is quite different from that of the traditional notarial certificate, which determines its absolute advantage over the traditional notarial certificate. On the one hand, it meets the people's requirements for efficiency in the digital age; On the other hand, it also strengthens the authenticity and legal validity of notarial documents. Its interactive feature adapts to the Internet era thinking of emphasizing interaction, which makes all parties involved in notarization enter a positive interactive state. Finally, the dynamic nature of the generation of the public certificate of the blockchain greatly gives play to the initiative of the notary organization, rather than passively confirming the existing evidence documents, which can give full play to the original preventive function of the notary.

5.
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
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, independencebased 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, safetyas 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. Anonymityunless 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
6. 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.

7. Little knowledge of blockchain: what are the characteristics of blockchain
nowadays, blockchain has become an area of public concern, and many enterprises have already studied the implementation of this technology. However, there are still a large number of people who are not familiar with the relevant concepts of blockchain technology. Recently, Viking Research Institute and think tank a jointly proced the blockchain instry dictionary. Bianews, as a media partner, has been authorized to popularize the knowledge of blockchain every day
today, bianews will bring you a little knowledge of blockchain. (2) the characteristics of blockchain
1. Anonymity / anonymousness because the data exchange between the nodes of the blockchain follows a fixed and predictable algorithm, the blockchain network does not need to be trusted and can exchange data based on address rather than personal identity
2. Autonomous / autonomous blockchain adopts consensus based mechanism, which enables all nodes in the whole system to exchange data, record data and update data freely and safely in a de trusted environment, without any human intervention
3. The open / openness blockchain system is open, and any node can have the total account book of the whole network. Except that the private information of the parties directly related to the data is encrypted by asymmetric encryption technology, the data of the blockchain is open to all nodes, so the information of the whole system is highly transparent
4. The digital nature of programmable / programmable distributed ledger means that blockchain transactions can be associated with computing logic and are programmable in nature. Therefore, users can set algorithms and rules to automatically trigger transactions between nodes
5. The traceability / Traceability blockchain stores all the historical data after the genesis block through the block data structure, and any data on the blockchain can be traced back to its origin through the chain structure
6. Tamper proof / after the information of tamper proof blockchain is added to the blockchain through consensus, it is jointly recorded by all nodes, and the mutual correlation is ensured through cryptography, so the difficulty and cost of tampering is very high
7. The collective maintenance / collectively maintain blockchain system is jointly maintained by all the nodes with maintenance function. All nodes can query blockchain data and develop related applications through open interfaces
8. No license / permissionless no license means that all nodes can request to add any transaction to the blockchain, but only if all users think it is legal.

8. Femtosecond detection found that blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system. Its characteristics include:
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
thanks to the decentralization of blockchain, bitcoin also has the characteristics of decentralization [6]
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
