How to act on blockchain
We need to establish data layer, network layer, consensus layer, incentive layer, contract layer and application layer
1. The data layer encapsulates the underlying data blocks and related basic data and algorithms such as data encryption and time stamp
2. The network layer includes distributed networking mechanism, data transmission mechanism and data verification mechanism
The consensus layer mainly encapsulates all kinds of consensus algorithms of network nodes The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuing mechanism and distribution mechanism of economic incentives5. The contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain
6. The application layer encapsulates various application scenarios and cases of blockchain
, general secretary of the CPC Central Committee, stressed in the eighteenth collective learning of the Central Political Bureau, "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". <

the forward-looking judgment of the CPC Central Committee has brought the "blockchain" into the public view and become the common focus of financial capital, real economy and public opinion
from network power to big data, from media integration to blockchain, the Politburo of the CPC Central Committee has collectively studied and aimed at the forefront of technological change, showing the direction, foresight and foresight of the CPC Central Committee, leading the pace of China's instrial change and economic transformation. This collective study of the Political Bureau of the Central Committee of the CPC, with special emphasis on "blockchain", has opened up an imaginary space for the development and application of blockchain
from the perspective of science and technology, blockchain involves many scientific and technological issues such as mathematics, cryptography, Internet and computer programming. From the perspective of application, in short, blockchain is a distributed shared ledger and database, which is decentralized, tamper proof, traceable, collective maintenance, open and transparent
these features ensure the "honesty" and "transparency" of the blockchain, and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the fact that blockchain can solve the problem of information asymmetry, and realize the cooperative trust and concerted action among multiple agents
blockchain is composed of a series of data blocks generated by cryptographic methods. Each block contains the hash value of the previous block, which is connected to the current block from the original block to form a blockchain.
Musk's main purpose is to promote bitcoin better. He has promoted bitcoin to the outside world many times before it is well known that musk likes bitcoin. He not only uses his own money to buy bitcoin, but also uses bitcoin as the reserve capital currency of his company. This time, musk changed his nickname to currency master, obviously in order to better promote bitcoin. Musk also said earlier that it would consider receiving bitcoin to trade Tesla in the future. It is also driven by musk that the price of bitcoin has been rising since last year, reaching record highs repeatedly
For blockchain messages, bitcoin is to blockchain what e-mail is to the Internet. As we all know, e-mail for the first time in the history of human information dissemination and exchange realizes the function of timely, free and verifiable sending data to anyone else in the world. Both the sender and the receiver can save copies of the data sent in e-mail. However, the e-mail data copies retained by both parties also become an inherent defect of online value transfer, because both parties have their own value. Therefore, it is necessary to ensure that the value is not double paid by the existence of third-party institutions, such as banks, stock exchanges, clearing centers or notaries. As an internet protocol, bitcoin can transfer value to each other instantly and safely without the existence of intermediary organizations such as credit granting third party, which reces transaction cost and improves transaction efficiency. Xiaobian now arranges the schematic diagram of blockchain technology and related technical principles for you
literally, blockchain is a distributed account book system composed of a series of data blocks generated by cryptographic methods. Each data block contains a large amount of transaction information, which is used to verify the validity of its information and generate the next block. These blocks are arranged in the order of generation, and each block is a node
the remarkable feature of blockchain is that there is no third-party supervision as a central server, and the transaction information in the block cannot be changed. The information contained in the block can be financial transactions or any other digital transactions, including documents. The success of the Internet business model, which has dominated the business world of human society for a long time, depends on the third-party financial institutions as credit granting institutions to process and mediate electronic transactions. The role of the third-party credit granting institutions is to verify, protect and save transaction records
However, there are still a large number of fraulent online transactions, which need to be mediated by a third party, resulting in higher transaction costs. Bitcoin, based on blockchain technology, uses encryption to prove, rather than credit a third party, so that all parties willing to trade can achieve online transactions through the Internetevery transaction can be protected by digital signature and sent to the "public key" of the receiver who uses the sender's "private key" for digital signature. The owner of bitcoin, namely cryptocurrency, needs to prove the ownership of its "private key" in order to consume and trade online. The receiving party uses the sender's "public key" to verify the digital signature on the transaction, that is, the ownership of the other party's "private key"
each transaction is broadcast to each node in the bitcoin network and recorded in the public ledger after verification. Moreover, before each transaction is recorded in the public ledger, it needs to verify its validity. Therefore, the verification node needs to ensure two things before recording each transaction: that is,
(1) consumers have the signature authentication of their encrypted electronic currency
(2) there are enough encrypted e-money in consumer accounts
Figure 1 shows the transaction process and principle based on blockchain technology
I hope this answer will help youAbout 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
