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. The era of blockchain 1.0 is the era of digital currency, and the technical basis is:
1. Lianzhuang data block structure based on blocks
2. Network wide shared ledger
3. Asymmetric encryption
4. Source code open source
blockchain 2.0 era technical basis:
1. Smart contract; It is an application in the blockchain system. It is a business logic that can run automatically by coding. It usually has its own token and special development language
2. DAPP: it includes the user's applications, including but not limited to various cryptocurrencies, such as Ethereum wallet
3. Virtual machine: used to execute the compiled code of smart contract. Virtual machine is Turing complete
with the application and deepening of blockchain technology, the era of blockchain 3.0 has come. The mode of blockchain cooperation can be seen from behind the operation of all walks of life. Therefore, blockchain will change the way of human life widely and profoundly, so the whole life service will enter the era of blockchain. In the process of Internet development, blockchain + physical instry, blockchain e-commerce and blockchain community operation can be applied to blockchain technology
of course, 3.0 came into being with the development of modern cryptography. Today's applied cryptography is the result of cryptography 20 years ago. Therefore, in order to apply blockchain technology to more participation scenarios, especially in Internet economy and other aspects, more verification is needed to verify whether the existing encryption technology can meet the demand, and more in-depth integration of cryptographic frontier technology and continuous innovation are needed.

5. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm for building trust and acquiring rights and interests between different nodes in the blockchain system.
blockchain is an important concept of bitcoin, which is essentially a decentralized database and serves as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chained data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access A new distributed infrastructure and computing method for programming and operating data by using intelligent contract composed of automated script code

6. Go language is the mainstream language of blockchain
according to the data survey of boss Research Institute, go and C + + are the mainstream languages of blockchain Posts currently recruited. The early blockchain system and application
programs are mainly implemented in C + +, and now most companies will use go language to
build public chain systems<
C + + is suitable for the development of local programs.
go language is suitable for the development of network programs and local programs.
compared with C + + go, it has the following advantages:
garbage collection
clear meaning
unified format
disadvantages:
efficiency is not as high as C + + at present, but for desktop programs, efficiency is not a big problem, Because hardware is fast growing.
C + + is the mainstream language at present, and I believe it will become a classic just like C.
to become a classic means that people who learn it can get a good salary, but it is only good for themselves.
in the future network world, go will have a big chance to get hot, I think it has a bright future.
the developers of go, including the founders of UNIX and C language, are the first generation of hackers, and I believe they will do a good job.
now the go stack + blockchain market is out of an unprecedented gale, and the situation is gratifying.

10. Development trend:
1. Development trend of core key technologies
from the point of view of the current technology and application of blockchain, its core is distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other existing computer technologies. With the deepening of blockchain application, new and higher requirements will be put forward for these core technologies. The research results in consensus mechanism, security algorithm, privacy protection and other related technology fields will play an important role in the leapfrog development of blockchain technology and application, and will be very critical to the continuous innovation and breakthrough of these technologies
(1) the development trend of consensus mechanism
in the public chain, the common consensus mechanism has the disadvantages of low performance and high energy consumption“ The "side chain" technology can only solve some problems under certain conditions. At present, most of the mainstream consensus mechanisms in alliance chain are based on pbft and its variants. Although access control can greatly improve the performance, it also sacrifices the efficiency, constraints, fault tolerance and other aspects of the consensus. It can be predicted that consensus algorithms and decision-making with universality and better performance for some typical scenarios will continue to appear
(2) the development trend of security algorithm
security is particularly important for financial application systems. On the one hand, most of the traditional security algorithms currently used have potential "backdoor" risks, which need to be replaced by more secure national security algorithms, and the strength of the algorithms also needs to be upgraded; On the other hand, we should also prevent some new technologies, such as quantum computing, from impacting or even subverting the traditional security algorithms
(3) development trend of privacy protection
at present, the privacy protection related to blockchain is still relatively weak. Especially for sensitive data, we need to balance privacy protection and compliance supervision. Information privacy protection technology, such as zero knowledge proof, homomorphic encryption, is also an important direction of follow-up development
the above core technologies tend to be low-level computer technologies, and their development requires considerable personnel and time investment, which will be a progressive process. The research achievements and cooperation of related enterprises, scientific research institutions and colleges and universities in these fields are very important for the development of blockchain technology
2. Development trend of general development platform
at present, many IT enterprises, consulting companies, communities and technology alliances have invested in the application research and development of blockchain, established and improved the general development platform, which has a great role in promoting the application of the whole blockchain technology
similar to IAAs (infrastructure as a service) and PAAS (platform as a service) of cloud computing, the blockchain general development platform is composed of infrastructure support layer, blockchain core component service layer, and corresponding development test suite, which can provide one-stop, low-cost technical services for building and deploying blockchain applications. At present, there are some such platforms. With the rapid development of blockchain applications and the strong investment of relevant participants, its service coverage, R & D convenience, operation and maintenance intelligence, as well as high stability, large capacity and low cost are the predictable development direction.
