How to upload data to 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
At the beginning of self-learning blockchain related knowledge, we can adopt the "bottom-up" method, that is, through reading books, reading white papers , we can check the information , and then summarize and connect these knowledge , and integrate them into a relatively complete knowledge system so I went to the bookstore and bought a of the Analects of Confucius. I read it from the beginning to the end and found that there were too many details and insights in it, which could not be transmitted through any interpretation. Actually, I spent a lot of time and read a lot of interpretation before. I really want to abandon the essence and pursue the end. I have to work hard it's the same in every field. When you don't understand it, you will have a kind of inexplicable fear of it, thinking that it is high and unattainable. In order to step into these fields quickly, you will look for a lot of so-called "interpretation" and "news" around it 2. technical perspective Basic Stage: 1. Blockchain Development Guide - author Shentu Qingchun: the author's research on the bottom layer of rendant bitcoin is very in-depth, and the explanation is very easy to understand 2. Blockchain technology guide - author Zou Jun: as the first domestic book to explain blockchain from a technical perspective, it is worth reading. Since its publication in 2016, it has been consistently evaluated well 3. Principles, design and application of blockchain by Yang Baohua and Chen Chang: as the CTO of Zhigui, Chen Chang remembers that the previous ink chain was based on hyperledger fabric, so this book has a thorough explanation of hyperledger related open source procts 3. Blockchain world is divided into two parts. The first part comprehensively reviews the birth, growth and graal development of blockchain in 2008 through full and accurate information, introces in detail the originality of blockchain technology, the scientific mechanism and the artistic logic, and introces the application characteristics of blockchain through more than ten instry scenarios such as finance, anti-counterfeiting and medical treatment. In the second part, combined with the spirit of G20 summit and the 13th five year plan, the author explores the combination of blockchain and digital economy, as well as the author's views and suggestions on the development trend of the instry
ICO trading is roughly divided into two parts, one is OTC trading, the other is exchange trading. There are three ways to go to the exchange, the first is to vote on the currency, the second is to invest in the currency, and the third is to cooperate with the project party
for the exchange, the more platform coins consumed by voting, the better; For the project side, the lower the cost, the greater the impact of users, the better; But for ordinary social users, the easier it is, the better
What does the project party need to have
{rrrrrrr}
the cost of project docking with the exchange:
at present, the popular Matcha exchange generally has about 12-15 BTCs,
biki and gate exchange have about 10 BTCs,
ZG exchange has many choices when docking with 6-8 BTCs,
2-5 BTCs, such as Lein, ZBG, fcoin, WBF and so on
Fcoin, which is relatively cost-effective, is also a good choice. Later, the project parties can work together with the platform to do activities, whether it is airdrop, IEO or other can be discussedAccording to experts, blockchain can be understood as a distributed public ledger, which is connected by various blocks into a chain. In the traditional bookkeeping system, the bookkeeping right is controlled by the central server
on the "account book" of blockchain, every point in the chain can record information on it, forming a point-to-point accounting system. Therefore, blockchain technology is considered as a decentralized technology
For example, in a village of 100 people, Zhang San bought a cow from Li Si and paid him 10000 yuan. In the past, he had to rely on Zhao Liu, a middleman, to transfer his 10000 yuan to Li Siwith the blockchain system, Zhang San can directly record his 10000 yuan to Li Si's account book, and the transaction information will be transmitted to the whole village, that is, the whole blockchain system, so that other 98 people can see the information. The whole transaction process is recorded by the system, which has the advantage of traceability to prevent the loss of Zhao Liu's account book or Li Si's denial of account

in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain became the core component of electronic currency bitcoin: as a public account book for all transactions. By using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently
the blockchain invented for bitcoin makes it the first digital currency to solve the problem of repeated consumption. The design of bitcoin has become a source of inspiration for other applications
of course, you can withdraw cash from local banks when you receive acceptance in other places you can ask the bank customer service according to the customer service of the bank
