Dahua blockchain is a book published by Tsinghua University Press in September 2019, written by Zhang Yingping. This book is a blockchain book that comprehensively explains bitcoin, Ethereum, super ledger and EOS, a blockchain development guide from engineer basic skills, development language to smart contract development, and a blockchain engineer guide from technology, project to career development planning
"Dahua blockchain"
"Dahua blockchain" is a blockchain book that pays equal attention to theory and practice, easy to understand and professional. The blockchain technology guide (the first three chapters) mainly explains the concept of blockchain, blockchain applications, bitcoin, Ethereum, super ledger, EOS and other mainstream blockchain technologies. Through learning, each reader can fully understand the implementation principles of mainstream blockchain technologies and understand the future development trend of blockchain. The practical part of development (the last two chapters) starts from the basic skills of blockchain, simulates the development of real blockchain projects, and explains in detail the design, development and deployment of smart contract and DAPP. Through learning, every reader can master the development of blockchain
2. General information and community websites, such as Babbitt and golden finance, Q & A websites such as coin watch and coin, and we media such as alpaca blockchain and vernacular blockchain are also very good. You can also search chainview.
3. Blockchain can make money in the following ways:
first, R & D and proction
as the source of blockchain technology application, in the field of R & D and proction, there are three main forms:
1. Coin making: using blockchain technology to solve some traditional problems. This mode is the mainstream of blockchain instry entrepreneurship, which is commonly seen in some start-ups, Their solutions often provide some tokens to support their development, so I call it mint for short. For example, cloud storage tries to solve the problem of cloud storage by issuing token SC; Bitstocks provide a decentralized exchange and issue token BTS; Press one wanted to try to reconstruct the content ecology and issued a token PRS. This mode, with the booming of blockchain investment market this year, especially ICO, has also brought huge market value to start-ups. It is possible that a blockchain project has been valued at hundreds of millions of Yuan before its specific procts are listed. For example, the current market value of EOS is more than 400 million US dollars
2. mining: assist the mint team to proce tokens. If Mint is to develop a new type of token, mining is one of the specific means of proction. However, not all tokens support mining. Only coins with pow (proof of work) mechanism support mining. The most famous one is bitcoin. Mining efficiency is closely related to computing power. At present, it is basically large-scale mining, and it is difficult for ordinary people to participate. In addition, mining is not the only way to proce tokens, and investment risk is relatively high
3. Outsourcing: to provide technical solutions in the field of R & D, another mode is to provide blockchain solutions for teams without blockchain technology capabilities
around this emerging technology, there must be more and more similar projects. As for whether it is reliable, we should be more careful. Summary: on the whole, in the field of R & D and proction, it is more suitable for organizations to enter, and there is limited space for indivials to dig for gold, so here is a brief overview< Second, financial circulation
no matter what kind of token comes out, it will always circulate, so there is a lot of demand in the financial field. For an organization, there are two common practices:
1. If there is a demand for trading, there is a demand for trading website. Although the transaction fee is cheaper than the stock, when the transaction is frequent, the transaction fee is rich enough. After several years of development, there are many trading websites on the market. However, if we look at the long-term development of the blockchain instry, the current number is probably not enough. Most importantly, judging from Jimi's current experience, most trading websites are not satisfactory. It's either a temporary outage or a visit to Caton. The recharge efficiency is low. In the era of mobile Internet, there is no app... The more places users feel uncomfortable, the more opportunities they have. There are two forms of trading websites. One is for the trading of listed tokens, such as bitage, cloud coin, China bitcoin, etc; One is to raise ICO for new projects, such as crowdfunding, icoinfo, ico365, etc
2. For fund investment, if 2C is used for trading website, 2b is used for fund investment, with high threshold. There are mainly two forms: venture capital and investment in various blockchain start-ups. This kind of fund requires more capital threshold, of course, the return is the real equity. Participating in pre-ico means participating in token raising before ICO. The advantage is that you can buy tokens at a lower price. If the project is good, the return is amazing. Compared with venture capital, this kind of investment requires less capital
for indivials, the threshold is much lower. There are mainly three ways:
1. ICO
you can understand it as a new issue in the stock market, and you can hold tokens at a lower cost. When the market is good, token listing can get dozens of times of growth. Even if there is no good market, the cost is relatively low later, which is a relatively safe way of investment
2. Currency speculation
just like trading stocks in the Shanghai Stock Exchange, buying and selling tokens in major exchanges is the most common way of investment for most people, which is generally divided into spot speculation and futures speculation, which will not be repeated here
3. Move bricks
unlike stocks, a token can be used on multiple platforms, including domestic and foreign. Due to the different game situation of each exchange, it is difficult to keep the same price of the same currency in different exchanges, which in fact leaves room for spread arbitrage. Of course, with the increasing number of brick movers, the price gap will be quickly flattened. What's more, moving bricks also faces many risks, such as exchange rate, handling charge, market fluctuation and so on. Now it's more and more difficult. Summary: compared with R & D and proction, many retail investors have entered the financial sector
thirdly, as an emerging instry, peripheral support has many opportunities to make money besides R & D, proction and financial circulation
1. Tools
because blockchain is close to money, people pay close attention to it. Around its daily use, a lot of tools are needed. Take a few common cases: market inquiry: This is almost a must for many investors every day, which has proced solutions in various scenarios, such as the price search robot in wechat group, the global index of blockchain in small programs, and the sobtc in app. Security: after all, it's gold and silver. Security is also the focus of every investor's attention. For example, Google identity authentication, Taiyi passport, etc. are tools for security
2; Forum
an emerging field, there is always a demand for information and communication, so there is media; The needs of the forum. For example, the official account of the media area, the "vernacular block chain" that hatched out of the small circle is a typical case. In less than 1 months, the target of 0 to 10000 powder has been completed. Around the blockchain content, in addition to we media, we can also make websites, forums, audio, video and even live broadcast. As far as the current observation is concerned, the market has not yet formed a monopoly, and there is still a lot of room for the market. 3. Content payment
because the instry is too new, there are few related content procts. There are several things to do:
1) as an emerging investment proct, investor ecation is a little understood by many investors about blockchain, resulting in a lot of learning needs, At present, there are two common ways: online class mode: listen to the music through a piece; Qianchat and other courses popularize the knowledge of blockchain, such as the previous lessons of laomao. Community model: carry out investment practice and communication through small secret circle (now renamed knowledge planet), such as Jinma's small secret circle
2) as mentioned in the developer training, one of the ways to make money in R & D field is coin making, and the technical talents needed for coin making are urgently needed in the market. Therefore, offline, there are many training courses for blockchain technology, which are not reliable. In addition, this is really a big market
3) if the first two types of instry research reports are aimed at indivials, then most of them are aimed at some enterprises.
first, R & D and proction
as the source of blockchain technology application, in the field of R & D and proction, there are three main forms:

3) if the first two types of instry research reports are aimed at indivials, then most of them are aimed at some enterprises.
4. The development cost is about 500000 yuan. It's very easy to find websites with blockchain information types. You can network "blockchain network" and "blockchain XX network" and other information stations. There are at least thousands of them in China. No, let's go online.
5. With the rapid development of blockchain in China, capitalists, entrepreneurs and indivials want to enter the blockchain instry as soon as possible, which makes it develop rapidly. However, at the same time, there are many enterprises camouflage blockchain media. I hope you all know
the blockchain media that I usually pay close attention to are: read coin, confirm finance and economics, and coin Xiao. These three are enough, too many words will easily affect their own judgment.

6. Blockchain time zone (hotblocktime)
7. PGC content of small chain finance is better, UGC of currency world is better, depending on your needs
8. Ethernet information blockchain, English Name: Ethernet moeher information, referred to as "eth. M", is committed to the development and construction of big data intelligent blockchain ecology based on the mature blockchain technology of smart contract Ethereum. Every business data will be realized as an intelligent contract, which can realize the existence and ownership of data, And it can trade independently of any specific content platform. This will help rece the dependence of business data providers on their platforms to ensure revenue from their markets and, in turn, on advertisers. Eth. M will be deployed as ERC 20 standard token on eth blockchain. Eth. M will also be used to create and motivate an intelligent business ecosystem to help create, manage data providers and redeem eth. M participants, as well as for digital asset allocation, certificate of ownership and asset transfer
eth. M is characterized by providing a complete intelligent business blockchain architecture for enterprise users and government partners on the Bi platform, providing users with a perfect data import scheme and a variety of classic distributed computing models, which can more quickly solve users' massive data computing problems and effectively rece enterprise costs, And create a new business model on the basis of data security. Blockchain is a new field that needs to be combined with market demand. We can solve some pain points in the instry in data storage security, data retrieval and data filtering. For blockchain framework, business model and technology, we focus on building mature blockchain procts with the most appropriate and proven technology
blockchain, originally just a settlement system of bitcoin, is essentially a decentralized accounting scheme based on cryptography. The technology used by blockchain itself is not a new concept, but a collection of cryptography technologies. Through ingenious design, it realizes the demand of decentralized settlement. However, it is accompanied by some derivative problems. Users are used to transferring and sharing information in the distributed storage space, namely Internet. However, if we want to complete the transfer of money value, we are used to using centralized and trusted third-party transaction intermediaries, such as banks. Although online payment is becoming more and more popular, bank card and password are still needed to register online payment account. The use of blockchain transactions is decentralized and does not require a third-party intermediary. Blockchain realizes the following three important functions: recording transaction information, verifying identity and establishing contract. It's going to be a big change. Because around the world, financial services are the largest sector in terms of market value. Even if it replaces a small part of business, blockchain can have a huge impact on the traditional financial field. At the same time, eth. M blockchain will also improve the efficiency of data management in the whole field. The function of establishing contracts will make the value of blockchain not limited to the financial field. This is the core of eth. M. blockchain can be used to store any information, even software code. That is to say, it can be realized by programming. When the relevant parties provide the relevant key, the transaction can be executed. The same program can also be used to obtain external data: stock index data, weather, news headlines or other data that can be analyzed by computer. In this way, the pre verified contract can be executed automatically when the specified conditions are met. Contracts executed on the blockchain are called "smart contracts"
in the future, eth. M's smart contract application scenarios are very wide, for example:
1. In the field of electric power, if the smart temperature regulator is used to collect the power utilization status of the smart grid in real time, when the wattage consumed by a certain company is monitored to reach a certain amount, the company account and the electric power company's transfer will be completed, and the automatic payment will be realized
2. In the medical field, if a doctor / patient stores the data of blood glucose meter in the form of blockchain, then the patient's physical sign data can be completely and accurately recorded. Blood glucose data can trigger insulin controller to help patients control blood glucose in a safe range
3. In the field of intellectual property supervision, blockchain can be used to monitor the number of times users use, share and a protected proct.
