Blockchain key

1.

blockchain is an important concept of bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it can not be tampered with and forged by cryptography

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code

extended data:

the evolution mode of blockchain is as follows:

& 9642; Blockchain 1.0 - digital currency

▪ Blockchain 2.0 - digital assets and smart contracts

▪ Blockchain 3.0 - Implementation of distributed applications in various instries

blockchain features:

1. Disintermediation. Due to the use of Distributed Accounting and storage, there is no centralized hardware or management organization in the system, 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

2. 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. Anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. 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

The information can not 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. Therefore, the data stability and reliability of the blockchain are extremely high

5. Anonymity. Because the exchange between nodes follows a fixed algorithm, the data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective). Therefore, the counterparties do not need to make the other party trust themselves by disclosing their identities, which is very helpful for the accumulation of credit

2. Nodes are the places where the blocks are connected, and the blocks need to be chained to be useful
core analysis:
1. Transparency, 2. Openness, 3. Information can not be tampered with, 4. Decentralization,
5. Detailed analysis
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

About dragonex dragon token

1, basic introction

Dragon token (DT) is a token issued by dragonex based on Ethereum erc20 standard, and each dragon token stored on the platform has the right of project dividend

every day, the transaction commission income of dragonex project will be distributed to all dragon coin holders according to the holding proportion of dragon coin

2. mining method

longcoin can not be obtained through ICO or pre excavation

all dragon coins can only be generated in the form of "mining", and the only way of mining is to trade on the platform“ Miners (i.e. platform users) contribute to the platform through trading behavior, and the platform issues dragon coins to miners as rewards

the total number of dragon coins issued was 37339500, and promised never to be issued

3. Release rules of dragon coin

Dragon coin is a token based on Ethereum smart contract. Since the launch of Genesis, the smart contract will be released for a total of 3650 times, with an interval of 24 hours and a cycle of 365 times

in the first cycle, 51200 dragon coins will be released each time; The yield of each cycle will be 50% lower than that of the previous cycle

4. Longcoin distribution mechanism

the platform will make statistics on the mining situation of "miners" every day, and the statistical cycle is 0:00:00-23:59:59 on that day; Each time the smart contract releases the Dragon coin, the platform will allocate the new dragon coin to the corresponding "miner" account on the next day according to the statistical data

"miners" dig out dragon coins through trading behavior, but the excavated dragon coins are not 100% owned by miners, among which:

① "miners" get 30% dragon coin reward and

② market brokers get 20% dragon coin reward Market broker: if miner a uses the invitation link of user B when registering, then B is the market broker of user a)

③ dragonex project party gets 10% block dragon coin Award (frozen for one year: for project marketing)

(4) dragonex project party gets 40% block longcoin Award (permanently frozen: used for platform technology research and development, talent introction, project operation, buy back longcoin and destroy)

note: Singapore standard time (UTC / GMT + 08:00)

5. Longcoin dividend mechanism:

① 100% of the daily platform revenue will be distributed to longcoin holders according to the proportion of longcoin holdings

② the platform will take a snapshot of the balance of dragon coin holders at 23:59:59 every day. Since the Dragon coin g up on the same day will arrive the next day, the user can share the Dragon coin on the same day = snapshot data + dragon coin g up on the same day. Dividends will be paid the next day, in the form of usdt to each holder's account

③ dividend formula:

project party's income to be paid dividends = transaction fees + other income of the project

dividend income of currency holding users =

income to be paid dividends * [number of indivial dragon coins held / (number of issued dragon coins - number of destroyed dragon coins)]

6. Online time of dragon coins

Dragon coins began to "mine" and calculate dividends from November 2, 2017

e to the fact that Longyuan is still in the development stage, it can not be released to miners and market brokers. However, the project side will record the data of everyone, and after the development of longcoin is completed, the longcoin and dividends e to everyone will be distributed to the account

longcoin is expected to be developed before November 25, 2017, and will be traded online on dragonex platform. The specific online transaction time will be subject to the official announcement later
