1. Jinwowo analysis believes that blockchain mainly solves the trust and security problems of transactions. Once the information is confirmed and added to the blockchain, it will be permanently stored. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of data on a single node cannot be realized. Therefore, the data stability and reliability of blockchain are very high
e to the use of Distributed Accounting and storage, there is no centralized hardware or management organization, the rights and obligations of each node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system.

2. 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. Therefore, the data stability and reliability of the blockchain are extremely high.
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

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.
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

5. 1 - disintermediated trust, which has been repeatedly emphasized, is not decentralization but disintermediation
2-stability, reliability and persistence. Because it is a distributed network architecture, no central node can be attacked or attacked, it has stronger stability, reliability and persistence in the overall technical layout
3-strong security, consensus mechanism does not need the entry of a third party, but through one technology to achieve the completion of the whole transaction
4 - the transparency and non tamperability of the transaction
the above four points are the characteristics of blockchain technology application analyzed by Chongqing jinwowo group.

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. Blockchain is an effective way to enhance the authenticity and reliability of financial information.
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
