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
the first stage: blockchain instry and go programming for 5 weeks
the second stage: cryptography and consensus algorithm for 2 weeks
the third stage: Ethereum source code analysis and development for 3 weeks
the fourth stage: Super ledger and node.js for 2 weeks

2. In many cases of blockchain commercial application, we can always see the word baas. Baas is the abbreviation of blockchain as a service, which is translated into "blockchain as a service" in Chinese. So what is blockchain as a service baas? With this question, we will follow Xiao Wang of Renren blockchain technology team to discuss it carefully
according to Xiao Wang, the concept of blockchain as a service (baas) is mainly proposed by Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service combined with blockchain technology. For example, Microsoft's azure cloud computing platform and IBM's bluemix garage cloud platform all provide blockchain as a service baas
blockchain as a service (baas) is a space created by enterprises such as Microsoft and IBM from their own cloud service network to run a blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of baas nodes is to quickly establish the development environment they need, and provide a series of operation services based on blockchain, such as search query, transaction submission, data analysis, etc. these services can be centralized or decentralized to help developers verify their concepts and models faster. The service of baas node is reflected in: it is more instrumental and easy to create, deploy, run and monitor blockchain.

At the beginning of self-learning blockchain related knowledge, we can adopt the "bottom-up" method, that is, through reading books, reading white papers , we can check the information , and then summarize and connect these knowledge , and integrate them into a relatively complete knowledge system so I went to the bookstore and bought a of the Analects of Confucius. I read it from the beginning to the end and found that there were too many details and insights in it, which could not be transmitted through any interpretation. Actually, I spent a lot of time and read a lot of interpretation before. I really want to abandon the essence and pursue the end. I have to work hard it's the same in every field. When you don't understand it, you will have a kind of inexplicable fear of it, thinking that it is high and unattainable. In order to step into these fields quickly, you will look for a lot of so-called "interpretation" and "news" around it 2. technical perspective Basic Stage: 1. Blockchain Development Guide - author Shentu Qingchun: the author's research on the bottom layer of rendant bitcoin is very in-depth, and the explanation is very easy to understand 2. Blockchain technology guide - author Zou Jun: as the first domestic book to explain blockchain from a technical perspective, it is worth reading. Since its publication in 2016, it has been consistently evaluated well 3. Principles, design and application of blockchain by Yang Baohua and Chen Chang: as the CTO of Zhigui, Chen Chang remembers that the previous ink chain was based on hyperledger fabric, so this book has a thorough explanation of hyperledger related open source procts 3. Blockchain world is divided into two parts. The first part comprehensively reviews the birth, growth and graal development of blockchain in 2008 through full and accurate information, introces in detail the originality of blockchain technology, the scientific mechanism and the artistic logic, and introces the application characteristics of blockchain through more than ten instry scenarios such as finance, anti-counterfeiting and medical treatment. In the second part, combined with the spirit of G20 summit and the 13th five year plan, the author explores the combination of blockchain and digital economy, as well as the author's views and suggestions on the development trend of the instry
4. In 2017, he began to work in the blockchain instry for three years, which witnessed the instry from obscurity to sudden outbreak and then to calm. Let's make a conclusion first. If you are willing to spend money, I suggest you go to professional IT consulting and delivery companies like ThoughtWorks / starwalker. In my understanding, the market is roughly divided into
1. The underlying chain platform providers, such as ant / network, usually only provide chain and development tools, but the specific instry / scenario solutions and development delivery capabilities are limited, which is not their focus. They want to use blockchain to package and sell more cloud services
2. Blockchain solution companies usually provide blockchain solutions in their own familiar fields, but most of them are small and medium-sized teams or start-up teams. Most of them have little difference in blockchain technology capabilities and have a deep understanding in their respective fields
however, the biggest problem of such companies is that because the blockchain instry is still in its early stage, and there is no mature business model or profit model, most of them need external investment to continue their life, which leads to the difficulty in guaranteeing their service ability or continuous performance ability, and frankly speaking, their business is unstable
on the other hand, because it is not a professional end-to-end delivery or professional outsourcing, it does not have mature methods, team and project management to ensure the efficient and complete delivery of a blockchain solution. So for buyers, it is easy to get out of control in the process of project development, or it is difficult to get satisfactory delivery results in the end
there is also a common problem, that is, most customers do not know what to do with blockchain and how to combine their business to do a valuable and meaningful blockchain project. Under this kind of cognition, I blindly find a company to directly develop on the scheme, and it's easy to regret or even give up halfway after doing it. I see too many such projects, I can't figure out the situation, and I don't know what I want to do. It's easy to set up a blockchain. This kind of company usually does not have the ability of pre-sale business consulting, business analysis and planning, in other words, the ability to help you understand the situation. In a word, if you know what you want, it may be OK to find them. If you don't know, it's better to find a professional consulting company honestly
3. IT consulting and delivery companies, which are usually specialized in serving large customers in various instries, have a set of consulting and end-to-end delivery methods and team support. Well, there are not many blockchain businesses in these companies, because they are not limited to the narrow business of blockchain, such as Accenture or some domestic companies. However, ThoughtWorks is slightly different. It has a blockchain division, pre-sales consulting / business analysis services, and delivery services. Then it has blockchain projects in its own major customers in various instries. Automobile, finance, retail, energy, agriculture and so on

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 to establish trust and obtain interests between different nodes in the blockchain system.

Development of digital currency trading system
currency trading, legal currency trading, over-the-counter trading, C2C trading, contract trading, etc.
the functions are different, and the prices may be different
I hope the following pictures can help you
< P >7. Blockchain is a revolution in proction relations and also a change in the financial market. In the world of blockchain, no one can dect the price difference. In blockchain payment, customers settle accounts with merchants directly. The merchant's money arrives at the account immediately. This is the significance of blockchain payment. Blockchain + payment makes payment fairer, more transparent and lower cost
many people think that 2018 will be a year of "all people's money speculation". Some people will get rich overnight, while others will take orders. In the continuous downturn of the currency circle, the popularity of blockchain technology has never abated, and many investors have turned their attention to various blockchain projects. Many companies are planning and setting up blockchain companies to intervene in this field. However, in fact, although more and more companies are planning blockchain business, most of the business has no obvious progress, and basically has no profitability. Even e to the sharp fall of bitcoin in November last year, there are some problems such as operation failure, layoffs and energy rection
of course, in addition to the "blockchain craze", there are still many rational blockchain projects, especially in the field of cross-border payment with a market of 2 trillion yuan, which contains huge development opportunities. IBM, EDP, batj and other listed companies have been laying out blockchain + payment business for a long time. Take EDP company (experimental
Data
processor) as an example, As early as the birth of bitcoin and blockchain technology, we have concted in-depth research on them
previously, EDP was a leader in the field of electronic data, and has served many American online payment service providers, banks, financial institutions, etc., as well as cooperated with some e-commerce websites. It is precisely because of EDP's rich experience in these fields that it is well aware that there are obstacles in the field of payment, such as cost, efficiency and processing speed, which restrict the development of cross-border payment. To this end, EDP has built a blockchain payment platform, EDT. What EDT should do is to provide real value for e-commerce platforms and consumers, and to make everyone (at present, EDT's target market is mainly global Chinese) really able to use, and willing to use cryptocurrency for payment operations, not just limited to currency speculation and speculation
in fact, many defects in the field of traditional payment are e to the fact that there are many intermediate links in the traditional payment method. In addition, e to the dependence on third-party institutions, the whole payment system needs to pay the corresponding handling charges, which greatly affects the effect of payment. The distributed network structure of the blockchain provides a mechanism to maintain consensus between the buyer and the seller without contacting the central organization. The EDT blockchain payment platform can play the role of a super ledger. All nodes on the block network witness each transaction together and make distributed records to ensure the completion of the transaction. Theoretically, it can achieve seamless, fast and convenient payment.

for example, in the field of public charity fund tracing, the value of blockchain is that it can trace the whereabouts and uses of each donation. It is understood that the Alipay love donation platform has achieved donation data into the chain, the source of funds can be traced.
on the other hand, in the field of commodity traceability, blockchain enables every commodity to have an "ID card" that cannot be tampered with. It is reported that since the beginning of this year, many overseas e-commerce companies and overseas Taoists have begun to use the blockchain to trace the source. During the "double 11" period of this year, the commodities on the chain of home appliance manufacturers have begun to snowball growth. According to statistics, in tmall's "double 11" alone, 150 million overseas Amoy procts have achieved origin traceability
the value of blockchain in the circulation of bills and invoices is mainly to improve the efficiency of ordinary citizens and rece the threshold and cost. It is understood that at present, blockchain e-bills, blockchain e-invoices, blockchain e-prescriptions, blockchain insurance claims, etc. have been piloted in cities all over the country. If Alipay has implemented the first single block chain insurance claim, the user will submit the application to the compensation account until 5 seconds.
in the field of cross-border payment, blockchain has also been applied. In June this year, Alipay's first electronic wallet cross border remittance service based on block chain was launched on June 25th in Hongkong, China. The cost of each cross-border remittance is lower and real-time payment is realized.

The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system. Shengshi Huacai's blockchain technology is really good
10. The capital allocation system is roughly to apply for stock capital allocation for users, provide a certain multiple of funds, then allocate their accounts, and finally track their capital status. Due to the characteristics of blockchain, which is a distributed account book that can not be tampered with and forged, it can track every operation of the allocation system. It is safe and effective to use blockchain to develop the allocation system
there are quite a few enterprises developing the funding system, but the funding system developed with blockchain technology is very few. At present, the application of blockchain development system should be more Yingtang Zhongchuang, and the blockchain funding system scheme displayed by Yingtang Zhongchuang is also feasible.
