1. 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
3. Hello, it's a great honor to be here to answer your question. The following are some of my views on this issue. If there are any mistakes, please point them out. 1. The so-called blockchain technology, also known as the distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in database records
2. Blockchain is an innovative application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies in the Internet era. In recent years, the development and application of blockchain is of great significance to technological innovation and instrial revolution. This experience introces the relevant knowledge of blockchain technology
3. Blockchain is a distributed ledger, which can contain financial and / or non-financial transactions. It can be replicated (distributed) on multiple systems in almost real time through peer-to-peer network. Each participant "owns" the same ledger and gets updated when adding any transaction. Each participant helps to determine the inherent "invariance" of all existing records, Using cryptography and digital signature to prove identity, authenticity and enforce read / write access, there is a mechanism that makes it difficult to change history, and it is easy to detect someone trying to change it. Thank you very much for your patience. If you have any help, please accept it. I wish you a happy life! thank you!

4. Generally speaking, blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer
among them, the data layer encapsulates the underlying data block and related data encryption and timestamp technologies; The network layer includes distributed networking mechanism, data transmission mechanism and data verification mechanism; The consensus layer mainly encapsulates all kinds of consensus algorithms of network nodes; The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; The contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain; The application layer encapsulates various application scenarios and cases of blockchain. In this model, chain block structure based on timestamp, consensus mechanism of distributed nodes, economic incentive based on consensus computing power and flexible and programmable smart contract are the most representative innovations of blockchain technology.

The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system.
7. 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<

9. What is blockchain? The explanation given by the network is that blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system. What are the characteristics? As for the characteristics of blockchain technology, combined with the definition of blockchain, jinwowo Group believes that blockchain should have these four characteristics: decentralized, trustless, collectively maintained and reliable database. And from the four features will be extended to another two features: open source, anonymity. If a system does not have these characteristics, it can not be regarded as an application based on blockchain technology.
