1.
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. Do you want to learn blockchain development technology or just want to know what blockchain is? If it is the former, you can look at the code of other blockchain projects and learn about it first. If it is the latter, we can pay attention to some good blockchain we media. Blockchain is an emerging instry. There is no ready-made training course. It depends on self exploration and understanding.
3. ① What is digital assets
MBA think tank defines "digital assets": digital assets refer to non monetary assets owned or controlled by enterprises, existing in the form of electronic data, held in daily activities for sale or in the process of proction
in our life, direct consumption in Alipay is a common way to use digital assets, that is, the electronic payment system. Besides, we often use network office, Internet stocks, online reading or video broadcasting, which are using digital assets. For enterprises, online coupons or points are the use of digital assets, and some companies also distribute equity in the form of digital assets
2. Why digitalize assets<
as for the allocation of private digital assets, Xiao Feng, vice chairman of Wanxiang holdings and chairman of Tonglian data, said at a financial technology investment summit that in order to get more than expected returns, it means that we must adopt a different way of asset allocation from others. In the future, the most obvious opportunity for alternative asset allocation may be digital assets. In the next 10 years, This new asset class cannot be ignored. For the society, asset digitization is a major trend
the bat empire is soaring in the digital economy of the Internet. In recent years, Didi, meituan, P2P lending and ofo are all inseparable from two key factors: asset circulation and sharing economy. The most convenient way of asset circulation is undoubtedly to digitize assets! The essence of sharing economy is to make the real assets more convenient for resource sharing through intelligent digital way. Through technical means to rece the waste of resources and rece costs
for enterprises, asset digitization is the best solution to rece costs and increase efficiency. If the privacy file is encrypted and saved by technical means, the security will be far greater than that in the entity. And digital assets are also convenient for enterprises to manage. When the era of big asset management comes, asset management needs to face thousands of asset types, involving a large number of calculations, which can not be completed by manpower alone
③ why use blockchain technology to digitize assets
1. Distrust. Through the distributed system of the blockchain, the trust between people is transferred to the trust in the machine, and the machine will not cheat people - it has no feelings and only operates in its own way. This greatly reces the number of central links generated by trust. In some instries, intermediaries can even be removed. Supply and demand trust is entirely based on this magical machine
2. Decentralization. At present, if you want to transfer the equity you hold, you have to go through a lot of proceres and find different departments to do it well. It's a waste of time and money. If blockchain technology is combined with electronic contract, this problem can be solved. Shareholders can trade their shares just like buying and selling T + 0 shares, and they are also protected by law. What about cross chain technology Cross chain: for example, you directly use your shares to buy other people's digital rights, recing the steps of exchanging legal currency.) How convenient that would be
3. Highly transparent. Now the business's biggest fear is information opacity. The application of blockchain technology can solve this problem. As long as the public digital assets are set up, everyone can view them. If necessary, the number of assets held by the owner can even be displayed, and some shady transactions can be avoided
4. Anonymization. We often do "streaking" on the Internet carelessly. Our information is sold at a price in some bad companies. We check all the system records of a person for several hundred yuan. We can receive some sales calls from time to time in our daily life, and most of the fraud calls are successful only after we know your information. In the blockchain, we only display one address for transactions, which can effectively protect our own information and rece the possibility of information being sold publicly
blockchain technology is a "customized" technology for its security, confidentiality, openness and transparency in asset digitization.

4. Taobao, Jingdong, tmall, etc. can make us directly feel the use of blockchain technology. And these are also very convenient, so that people can quickly buy the goods they want, and can be compared, which is better.
5. 1、 With the progress of technology and society, great changes have taken place or are about to take place in the instrial structure of the society. One of the instries will take place great changes, or even be completely destroyed. That is the advertising instry, because the emerging we media instry will replace it or even surpass it< Secondly, the whole process of traditional advertising instry is divided into four steps:
1
2. According to the needs of the target customers, manufacture or revise their own procts and services
3. Find channels for users to know or accept their procts
4. Sell the procts and return the funds< Third, we media has provided all the services provided by the traditional advertising instry for enterprises or indivials comprehensively and quickly. Relying on modern technology, we media has surpassed the traditional advertising instry in many aspects:
1. The propaganda form of the traditional advertising instry is relatively monotonous, but multimedia can be spread in short video, medium video, long video, articles, pictures and other forms
2. The traditional advertising instry can't collect users' feedback information, but we media can directly count a large amount of information about the audience's age, location, viewing integrity, viewing time, attention direction and so on from all kinds of communication methods, relying on the Internet data, which can provide more accurate services for manufacturers (suppliers)
3. With strong technical support and data foundation, we media has the ability to design the whole case for users, and is more professional, effective and faster than the traditional advertising instry
Fourth, we media has a lot of development space and opportunities, but there are also many pitfalls in the instry. Understanding advertising does not necessarily mean understanding we media, so we need to learn and know why.
