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. If you are interested in blockchain technology, you can learn the knowledge of cryptography at the beginning, and learn how to strengthen contracts other than trust through numbers. This is the most basic principle of blockchain. Then you can look at the programming books, understand the basic code, and do simple programming. After that, you can download some common blockchains, Study its code arrangement, see how it adds contracts, and make simple modifications to build its own smart contracts. Of course, if you are only affected by the recent price and hype and decide to join the instry, I suggest you learn more about the Bulls who hype it, listen to their opinions, and learn how others reap!

3. As the best course in the water digital business school, the registration fee is definitely the most expensive, which needs 280000 RMB. However, since you can sign up for this course, you can prove that your economic income is very considerable. Moreover, if you sign up for the blockchain professional DBA, you will gain more in class, and the return is also very considerable.

4. He was the first bitcoin underlying technology to realize the sharing mechanism of point-to-point transmission of distributed data storage, so as to achieve the transparency and security of transactions. For example, six degree chain is actively introcing this technology. I think it is quite reliable.

5. There is a "chain College" in Beijing. There are weekend classes in technology and regular online and offline courses.

I want to know what blockchain is and what all kinds of currencies are for

this starts with bitcoin. Here we recommend the "bitcoin" by Li Jun, Chang Jia, et al. It can help you understand the common wisdom behind bitcoin, the principle of decentralization, the history of bitcoin, etc. Next, we will study various currencies. The larger domestic chains are qtum and Neo, and the larger foreign chains are EOS and eth. Study their white papers, teams, history, twitter, telegram groups, etc

at the same time, you also need a place where you can < EM > read the market, exchange ideas, and read articles < / EM > . Here are some common apps. For example, the commonly used app that looks at the price blockfolio ; You can use Babbitt app to read information, block news, news, and even find a place to brag; For currency information, please refer to non small app , which also contains a lot of content. Babbitt app is the one I use most, because its news is reliable and will not fake

blockchain practitioners

as far as I know, the current practitioners in the blockchain instry have transferred more from Finance or computer majors. If you are a college student, if you want to work in the blockchain instry, you can consider studying finance or computer instry. If you are already working and want to join the blockchain instry, you need to learn the following. A "blockchain: from digital currency to credit society" by Changjia and Han Feng, you can get started with the basic knowledge of blockchain< blockchain technology guide can help you deepen your understanding of blockchain technology Blockchain revolution can take you into an upcoming revolution. Generally speaking, there are many things to learn

7. 1. mining doesn't require you to press e to watch animation to dig slowly. It's too slow. Take the ck's beak hoe to attack the ore directly. If you use double holding and attack speed dragon roar, you will become a rotating excavator
2. After a forward attack, if you continuously tap the left button, you will trigger a continuous infinite jump chop. Don't think it's a hidden move. In fact, it's just a light hit to damage the pit father bug of B club;

8. The era of blockchain 1.0 is a bit network, with TPS value of 7 and an average block of 10 minutes
the era of 2.0 is Ethernet, with TPS value of 50 and an average block of 18 seconds
the era of 3.0 is EOS network, with TPS value of 3600 and an average block in 3 seconds
the TPS value of MAC has reached 15 million, 10 million level, an average of 0.3 seconds out of a block. In December 2018, it passed the official certification of the national certification body CFCA, and the TPS value can still reach 10 million level in the ordinary office environment
therefore, it is not too much to say that MAC has created the era of blockchain 4.0.

9. In the past two years, blockchain has never been known to the public, and has gained more and more people's attention. It is even becoming a hot emerging field. In fact, it has profound internal logic. However, except for a few companies or research institutions that have invested in it, most people's understanding of blockchain is still in the conceptual stage. They may know some features or technical terms, but they don't really know what it is. As a general technology, blockchain technology can really play the driving force, value and influence of technological innovation only by accelerating its penetration into other fields and integrating with all walks of life. At the present stage, mining high-quality projects has become the only way out of the long night for the whole instry< At present, the digitization level of medical and health field is still in the middle and lower levels, the information circulation is difficult, and hospitals are isolated from each other, which directly affects the efficiency and accuracy of hospital (related service institutions) to query patient data (cases, etc.), and leads to frequent disputes between patients and service institutions. Therefore, digitalization of the whole instry is imperative. At the same time, in the digital part, data security and privacy has become a new problem
these existing pain points can be solved from the root through Mac
the generation mode of blocks and the storage mode of data determine that the data stored on the multi source chain has the characteristics of integrity, non tampering, traceability, privacy protection and time order. These characteristics make the multi source chain have natural advantages in the complex, huge and numerous medical fields
the application of blockchain in the field of healthcare
in the field of healthcare, there are many use cases of blockchain technology, but let's focus on the most promising use cases:

1 health data
as patients move in different medical fields and systems, creating usable and highly complete health records is a big challenge in the field of healthcare. Blockchain may help by creating a reliable data source to track changes between systems and solve many problems related to data integration between private systems. In other words, blockchain can be the glue to integrate highly dispersed medical records
however, this quickly raises the most important non-technical question of blockchain: if a distributed ledger is the source of authority, who "owns" the right to access the part of the blockchain that "you" own? For patients, blockchain makes sense. It will give them more control over their data, because they (theoretically) hold the key to their data
2 medical privacy
in fact, we have all met the problems of personal privacy and data leakage, for example, when we just went to the hospital last week, we would immediately receive a lot of telephone harassment, all kinds of registered, drug sellers and so on
medical data is directly related to our life, health and personal property, so its privacy, security and accuracy are particularly important. But at present, the whole medical system is facing the problem of data sharing across platforms. Blockchain technology can help us better protect, circulate and use these very important data. Duoyuan chain is an active practitioner, trying to boost the transformation and upgrading of traditional medical instry with the potential of technology
specifically, multi source chain uses the characteristics of blockchain technology, such as decentralization, smart contract, tamper proof and information transparency, and combines with n medical resource providers to realize the functions of medical traceability, real-time tracking of data on the chain, resource circulation, etc., which can effectively solve the current situation of medical instry pain points and patients' difficulty in seeing a doctor
3 revenue cycle, reconciliation and fraud
the biggest cost burden lurking in the U.S. healthcare system is continuous tracking services and capital flows: the huge complexity and the distributed nature of our health system mean that it costs billions of dollars a year to try to understand which patients receive which services and which providers provide them. Disputes inevitably arise, and both the insurance instry and health care providers spend a lot of extra time and money to resolve them
e to its independent architecture, blockchain may become the foundation of high integrity tracking function, which can be updated in a near instant manner. This means fewer mistakes (including financial and patient care) and a significant rection in fraud. Given the scale of the field, this may generate enough interest to attract investment to help address these complex technical challenges. To solve the problems of fake drugs, high drug prices, excessive medical treatment, excessive drug use and so on
Application of blockchain in the field of life sciences
the direction of pharmaceutical / Biotechnology R & D is cross organization cooperation, sharing resources among companies, government agencies and research institutions, which is the core of its development. But agencies are often reluctant to share data because they are worried about data theft. Blockchain provides a possibility to hard code trust into the process of collaborative R & D in a magical way. More trust means more cooperation, which in turn increases proctivity
by exploring the impact of blockchain on indivials, the rise of personal genomics means that patients with gene sequences can control their own genome authorization in a way that was previously impossible. Therapeutic research is increasingly focused on genomic information mining. As an important potential technology for obtaining permission to enter indivial anonymous gene sequences, blockchain can give patients more rights, and it may soon become the mainstream technology
in addition, the opportunities of supply chain technology in network security, supply chain management, Internet of things data management and precision medicine of hospitals and pharmaceutical companies are also showing signs of rising
the digitalized medical resources have become "biomedical digital assets", which have strong liquidity, transparency and visibility. Blockchain is not only the infrastructure of the future digital economic society, but also an important magic weapon for the digital transformation of various instries. Embracing blockchain means embracing the future. Speed is the future, and mat multi chain is always on the way.
