1. 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

2. 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

3.
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

4. 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.

5. Blockchain technology has three obvious characteristics: openness, security and uniqueness
openness mainly refers to that the stored information in the blockchain is completely open to all participants. This is mainly determined by the point-to-point network storage mode of the blockchain. In the blockchain network, each node can store a of the blockchain, and the uniqueness of the blockchain can ensure that the is exactly the same between different nodes
security mainly refers to that the information stored in the blockchain block is saved after being processed by digital encryption technology, and only the private key holder can decrypt the information to obtain the real information. Other members can only see and verify the integrity and uniqueness of information, but cannot see the real information
uniqueness is mainly e to the fact that the information on the blockchain cannot be tampered with once it is on the chain, so it is unique. Of course, the uniqueness here also includes the uniqueness in space, that is, all nodes have only one version of information, and also includes the uniqueness in time, that is, the historical data cannot be changed. This uniqueness also means that the blockchain maintains the characteristics of a unique main chain in the process of operation, and once other chains appear, it is a bifurcation. The emergence of bifurcation will lead to the plication of blockchain in two different spatial dimensions. Of course, to solve this problem, we need to set reasonable consensus rules to avoid. When the concept of blockchain was hot, many related top domain names were registered and used as blockchain platforms.

6. 1-blockchain can drive the birth of a new business model
the characteristics of blockchain technology enable it to achieve some business models that are difficult to achieve in the centralized mode
2 - blockchain technology has a flexible architecture
according to different application scenarios and user needs, blockchain technology can be divided into public chain, private chain and alliance chain, which can be selected according to the actual use of institutions
the openness of 3-chain technology encourages innovation and collaboration
through the opening and cooperation of source code, blockchain technology can promote the cooperation among different developers, researchers and institutions, and learn from each other, so as to achieve a more efficient and secure solution
jinwowo will use blockchain technology to fully record big data sources and improve storage.

7. Blockchain has the characteristics of decentralization, non tampering, irreversibility and anonymity
Decentralization: because there is no central ruler in the whole network. The system relies on the fair constraints of multiple participants on the network, so the rights and obligations of every node are equal, and every node will store all the data on the blockchain. Even if the node is damaged or attacked, it will not pose any threat to the account book
tamper proof: ensure that information or contracts cannot be forged. If the account book is in someone's hands, the possibility of fraud is very high, but everyone has an account book. Unless more than 51% of the people in the whole game change an account, any tampering will be invalid, which is also the advantage of collective maintenance and supervision
irreversible: the information on the blockchain must be irreversible and cannot be destroyed at will. The system is open source, and the whole system must be open and transparent. Therefore, after a transaction is broadcasted across the network, it will be successfully recorded with more than six confirmations, and it is irreversible and irreversible. Note: imtoken is the confirmation of 12 blocks
anonymity: the identity information of each block node does not need to be announced or verified, and the information can be transferred anonymously. For a simple example, you initiate a transaction to a wallet address on the blockchain, but you can't know the exact person behind the address, or your private key has been stolen by a hacker, and you can't know who the hacker is from a wallet address.
