1. Go is an open source programming language, which makes it easy to construct simple, reliable and efficient software. If you want to learn this programming language, you should first find a good tutorial. Brother Lian's go language + blockchain training has recently published a new set of go language tutorial, and the teacher's speaking is very good
with the global hot discussion of the concept of "blockchain", the application of blockchain technology has been quietly added to the daily life scenes such as finance, logistics, credit reference, manufacturing and retail. Some experts have shown that the future blockchain will be closely related to people's lives, and the integration of blockchain technology and people's daily life is the general trend
the popularity of the blockchain market has triggered a large number of talents demand based on blockchain technical personnel, and the popularity of blockchain talents is rising at the speed of light. According to the "2018 blockchain high salary list" released by lagou.com, Tencent, Xiaomi, Suning, Jingdong and other domestic enterprise giants have released many high salary blockchain post demands, trying to explore blockchain related technologies and applications. It is also pointed out in the list that the demand for high salary jobs is mainly based on blockchain related technical jobs, among which Suning and Keda have been given the highest monthly salary of 100k
the huge market demand for technical talents will inevitably lead to the explosive emergence and growth of the whole blockchain training market. Most of the training modes can be divided into online training, traditional IT organization training, and offline short-term training camps, which mainly focus on high-end forms. However, in the process of the hot market evolution, there are also a variety of blockchain training chaos: lecturers' qualifications are watered down, and even the most basic names are not disclosed, the syllabus is opaque, and the teaching quality is shrinking, Unreasonable class arrangement and uneven training fees and so on
with the large-scale development of the whole blockchain training market, brother company ecation, together with Yin Cheng, a senior blockchain expert, and his Tsinghua Shuimu Weiming team, has set up a blockchain college. With its professional and powerful team of technical lecturers, detailed and comprehensive curriculum system, and a large number of authentic enterprise blockchain projects, it aims to deepen the blockchain teaching and training field, And train more professional technical talents for enterprises and society<
Yin Cheng, a senior blockchain technology expert, graated from Tsinghua University, is the dean of brother Lian blockchain college. He once served as Google Algorithm Engineer, the world's most valuable expert in the field of Microsoft blockchain, and the gold medal lecturer of Microsoft tech.ed conference. Proficient in C / C + +, python, go language, sicikit learn and tensorflow. With 15 years of programming experience and 5 years of teaching experience, senior software architect, Intel Software Technology expert, famous technology expert, with many years of working experience in the world's top it company Microsoft Google. He has many years of experience in software programming and lecturing, and has developed many procts in human-computer interaction, ecation, information security, advertising and blockchain system. He has deep experience in project management and R & D, has two AI invention patents, and has practical experience in developing e-money deployed to Microsoft Windows azure. Teaching explanation is in simple language, so that students can apply what they have learned

2. Concept analysis of blockchain: it is not only a concept but also a technical system
blockchain is a distributed system, which is constructed by cryptography. Indeed, blockchain is a technical collection of concepts formed by distributed system and cryptography. We should emphasize that it is not only a concept but also a technical system, At the very beginning, blockchain only represented the account structure of the underlying technology of bitcoin. It was a narrow concept. At the beginning, because the development of this technology should be represented by a special term to distinguish it from bitcoin, this word was used to refer to it, and it became a bigger and richer concept and a complete system
when we think back to cloud computing, cloud computing existed before the word cloud computing was put forward. However, once cloud computing was put forward, it developed rapidly along the concept of cloud computing. I think blockchain also has such characteristics, and it will continue to develop. Once it becomes a complete sub Technology system, all the technologies in the sub fields under blockchain will continue to develop, The algorithms in the sub domain will develop in the direction of qualitative change in the way of adding tests. Blockchain is a kind of distributed line or network trust technology. When I studied blockchain technology, there was no blockchain word. We called it distributed computing. On the technical level, end-to-end. From a macro point of view, the blockchain is composed of multiple nodes participated by Dongfang. It is equal. The cooperation of these nodes needs to complete the mutual verification on the blockchain. At this time, there is no need for a central node to do this
macro: distributed equal deployment system, participating nodes cooperate to complete verification and storage
microcosmic: rigorous data structure is packaged and stored in the block, and logically concatenated to form a chain
digital signature and integrity verification ensure the authenticity, real-time and timing of block data
at last, after learning all the technical features, it has achieved the multi fight, informed group and supervision right, because it is transparent, shared and open. All parties of the alliance should participate in the operation of the blockchain system, which is equivalent to a co construction, sharing, sharing and co governance. When constructing the alliance, I have to think of one thing: what I store to the blockchain, which are transparent and which are encrypted. At this time, I need to determine according to your business system. If someone deliberately cheats, he or she will probably find that your data may be tampered or forged with the participation of the public or even the collective alliance, so he or she will consider the cost of doing evil. In this way, the trust cost of the alliance will be greatly reced, and there will be no friction. Outside the alliance, because you believe that you have adopted the blockchain technology, you will have a higher degree of trust in the services or procts provided by the whole alliance, so this is a very good way of virtuous circle
what should you do to build a blockchain system or to bridge business to a blockchain system? There are two steps, very simple. The first step is to construct several key roles in your business logic. Now consider how many roles there may be. There may be many roles, but now consider them as one. These perspectives must be related in business logic. They need to share and map these rules to the blockchain or put them into scripts at the same time. Next, we will talk about data, which data will be put into the blockchain and which will not be put, because the efficiency of the blockchain is security, which is generally simple and key, and only what needs to be built together is considered. On the other hand, even if some data are put into the blockchain, not all things need to be supervised, but may be closed door, and can only be seen after authorization, One is privacy, the other is regulatory compliance
after the first step, the second step is simpler. You need a convenient and reliable blockchain platform. It is an underlying infrastructure, including books, networks, supply and demand algorithms, and accounts. All these things have to exist. After general checking, you can check and send these four blocks according to your business needs. There is a protocol below. The above layer is mapping. This mapping layer is very important. It abstracts your business into many models and logics, and abstracts them into an easy-to-use system. Then you can develop your business logic on the application system, and then develop the business logic based on the blockchain. This is a fast process. In fact, a good blockchain business platform should have its own application tools, as well as monitoring, viewing and auxiliary tools, just like the early days of the database. At the beginning of the database, if it was just data without auxiliary tools, it would be very difficult to run
next, let's share a small case, which is the case of blockchain business points that we just released. There are a lot of views that we have already discussed. We must use points to make it universal, so that consumers can get profits and businesses can rece the burden. Moreover, we can let points flow and guide real secondary consumption. This is of great significance. We have to consider more when we choose commercial competition. Commercial competition itself has a certain financial or monetary attribute. It is a purely low-risk number, because it has the lowest regulatory risk to the extent of compliance and legality. Second, points can quickly accumulate digital assets, accumulate C-end users, test your blockchain platform to a certain extent, and even test your blockchain technology to verify whether your blockchain platform is right. Finally, derived with financial related attributes, for the expansion of financial means behind all laid a good foundation
according to the path of building a blockchain system that we have just seen, the first step is to make decisions. In the blockchain system, it plays two roles: merchant and consumer. Merchants are also divided into two levels, the points they send, the points they receive, and the points they receive are also divided into two levels, the points they transfer out and the points they receive. Rules are non discrimination rules; Data, integral, some data are very interesting. I can write all the people on it, and I can write the effective information on it. There are some consumer behaviors, such as what to buy, coffee or bread. These data are written on it. I will use a simple example to guide you
the second step is to find a platform for blockchain. In our Bubi blockchain, what do we get? We really got a positive feedback. We think it's a very good feedback. First, digital integral represents a variety of data assets, which can be supported on the blockchain. Second, it may have many users, whether real users or laboratory simulation users. It's no problem to support millions of transactions and storage. Third, it really builds a good foundation for us, which lays a good foundation for the exploration in the financial field.

3. 1. What is blockchain? In a word
A: blockchain is an encrypted database chain, that is, the transaction data in multiple timestamps / events are encrypted and linked together, and the data can not be tampered with or shared
2. Performance and logic:
A. external operation forms: bank deposit and withdrawal, remittance, account in and out, shopping, currency issuance, capital transaction, etc
B. internal logic processing (software program): after human operation, the data will be encrypted first and then stored in the database. After the program, the data will be divided into regions, such as the data in the event and time stamp will be classified and put together into a region. Multiple events and data in timestamps are associated to form a blockchain. The encrypted data can be shared, but not tampered with
C. forms of sharing: querying personal information, auditing, etc. Query permission / sharing permission: different permissions can query different data. For example, the bank can query the information of all people, and the indivial can only query the indivial
3. Most of the examples are different, but the logic processing ideas are the same, but the implementation methods and operations are different
4. Blockchain: it has the characteristics of encrypted data, tamperable data and shared data
5. Blockchain Technology: the technology of encrypting, partitioning and sharing data with editing programs
there are suggestions for guidance
application fields: finance, it, commodity sales, online shopping, etc.

5. Blockchain is a technology, and the underlying technology of bitcoin is blockchain. Blockchain features: decentralization, anonymity, security, transparency, traceability, irreversibility, etc
according to the development of blockchain, it can be divided into three stages:
blockchain 1.0 stage: when the digital currency represented by bitcoin first appeared, it was probably from 2008 to 2014
blockchain 2.0 stage: from the birth of Ethereum to the eve of "94 event" in 2017, this is the development era of smart contract and blockchain
blockchain stage 3.0: after the "94 event", we began to pay attention to the exploration and development of blockchain applications and reshape the technology and value of blockchain
although blockchain technology has been widely recognized, people still cannot do without digital currency. After all, the underlying technology of digital currency is blockchain. Even though the non currency blockchain on the alliance chain can be advocated by mainstream regulators, it is much more difficult than the real decentralized blockchain such as public chain projects. What technology geeks pursue are often more difficult decentralized projects
therefore, digital currency will not be destroyed, which is the development trend. As for how you say to play, maybe you are asking how to play digital currency instead of blockchain? If you really want to deepen the understanding, you may as well go to Citex (big C network) to have a look, hope to adopt, thank you.

6. Go language + blockchain training course:
from the characteristics of the language itself, go is a very efficient language, which highly supports concurrency. Go language itself pays more attention to distributed systems, and concurrency processing is relatively good, such as advertising and search, which are high concurrency servers
go language advantages:
excellent performance, can be directly compiled into machine code, does not rely on other libraries, go is extremely fast. Its performance is similar to Java or C + +
concurrency is supported at the language level, which is the biggest feature of go. It is born to support concurrency, and go is the concurrency supported in gene, which can make full use of multi-core and make it easy to use concurrency
the built-in runtime supports garbage collection, which is one of the features of dynamic language. Although GC is not perfect at present, it is enough to cope with most of the situations we can encounter, especially GC after go1.1
it's easy to learn. The authors of go language all have the gene of C, so go naturally has the gene of C. There are 25 go keywords, but the expressive ability is very strong. It almost supports most of the features you've seen in other languages: inheritance, overloading, object, etc
rich standard libraries, go has built a large number of libraries, especially the network library, which is also my favorite part< As like as two peas, br / > built-in powerful tools, Go language is built with many tools chain, the best should be gofmt tools, automatic formatting code, make team review become so simple, code format is exactly the same, it is very difficult to think differently.
cross platform compilation and fast compilation. Compared with the sluggish compilation speed of Java and C + +, the fast compilation time of go is a major efficiency advantage
disadvantages of go language:
package management: package management of go language is absolutely not perfect. By default, it has no way to make a specific version of the dependency library, nor can it create replicable builds. In contrast, python, node and Ruby all have better package management systems. However, with the right tools, the package management of go language can also perform well
lack of development framework: go language does not have a major framework, such as Ruby's rails framework, Python's Django framework or PHP's laravel. This is a heated discussion in the go language community, because many people think that we should not start with using frameworks. This is true in many cases, but if you just want to build a simple crud API, it's much easier to use Django / djrf, rails laravel, or Phoenix
exception handling: go language can help developers deal with compilation errors by simply returning errors (or call stack) through functions and expected calling codes. Although this method is effective, it is easy to lose the scope of the error, so it is difficult to provide meaningful error information to users. Error package can solve this problem by allowing us to add context and stack trace to return error
another problem is that we may forget to handle errors. Static analysis tools such as errcheck and megacheck can avoid these errors. Although these solutions are very effective, they may not be the right way.

rich standard libraries, go has built a large number of libraries, especially the network library, which is also my favorite part< As like as two peas, br / > built-in powerful tools, Go language is built with many tools chain, the best should be gofmt tools, automatic formatting code, make team review become so simple, code format is exactly the same, it is very difficult to think differently.
cross platform compilation and fast compilation. Compared with the sluggish compilation speed of Java and C + +, the fast compilation time of go is a major efficiency advantage
disadvantages of go language:
package management: package management of go language is absolutely not perfect. By default, it has no way to make a specific version of the dependency library, nor can it create replicable builds. In contrast, python, node and Ruby all have better package management systems. However, with the right tools, the package management of go language can also perform well
lack of development framework: go language does not have a major framework, such as Ruby's rails framework, Python's Django framework or PHP's laravel. This is a heated discussion in the go language community, because many people think that we should not start with using frameworks. This is true in many cases, but if you just want to build a simple crud API, it's much easier to use Django / djrf, rails laravel, or Phoenix
exception handling: go language can help developers deal with compilation errors by simply returning errors (or call stack) through functions and expected calling codes. Although this method is effective, it is easy to lose the scope of the error, so it is difficult to provide meaningful error information to users. Error package can solve this problem by allowing us to add context and stack trace to return error
another problem is that we may forget to handle errors. Static analysis tools such as errcheck and megacheck can avoid these errors. Although these solutions are very effective, they may not be the right way.
