What are the characteristics 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
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
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
There are four kinds of minerals in the devil's land:
-
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
-
Gold Mine: it can be used to repair equipment with loss degree of 0 ＜ required quality of more than 5 ＞
-
silver ore and copper ore: these two ores have no major use, but some special tasks can still be used
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.
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.
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.
