1. Hu Kai's graate degree course distributed operating system. In recent years, he has published more than 60 SCI / EI retrieval papers in important academic journals at home and abroad, edited new technologies of network computing (416 pages, published by Science Press in 2001), and completed the national "Eleventh Five Year Plan" textbook introction to distributed computing system (490 pages, published by Tsinghua University Press in 2014).
2. blockchain empowers the development of real economy. With the development of blockchain technology, its application scenarios are more in-depth, from commodity traceability, judicial deposit, government affairs, supply chain finance, trade finance, social public welfare to instrial management, energy and power, data transaction, public resource transaction, digital identity, medical health and other fields. In the future, with the further development of blockchain technology, especially in terms of performance, scale and security, its application scenarios will be increasingly extensive
1) the life cycle of blockchain instry. By analyzing the market growth rate, demand growth rate, proct variety, number of competitors, entry and exit barriers, technological change, user purchase behavior of the blockchain instry, we can judge the development stage of the instry
2) supply and demand balance of blockchain instry market. By analyzing the supply, demand and import and export situation of the blockchain instry, we can judge the supply and demand balance of the instry, in order to grasp the saturation degree of the instry market
3) competition pattern of blockchain instry. Through the analysis of the bargaining power of suppliers, buyers, potential competitors, substitutes and competitors in the blockchain instry, we can master the five forces that determine the profit level of the instry
4) economic operation of blockchain instry. It mainly includes data analysis, including the number of competitive enterprises, number of employees, total instrial output value, sales output value, export value, finished procts, sales revenue, total profit, assets, liabilities, instry growth ability, profitability, solvency and operation ability
5) the main competitive enterprises in the blockchain instry. Including procts, business status (BCG), financial status, competitive strategy, market share, competitiveness (SWOT analysis), etc
6) investment and financing and M & A analysis. Including investment and financing project analysis, M & A analysis, investment region, investment return, investment structure, etc
7) blockchain instry marketing. Including marketing concept, marketing mode, marketing strategy, channel structure, proct strategy, etc

3. Yes, starting from the basic training, Xiao can learn it, regardless of ecation background. As long as you are willing to work hard, you will be able to learn it.
4. This Canon laser printer icmf426dw features many functions, such as: multiple function, high-speed double-sided printing function, deformation correction function, etc. I know so much, I hope I can help you!
5. Strange webpage links can be infected by viruses, so try to avoid using strange websites, and carefully open or click strange link e-mails
most viruses can be prevented by downloading security software from mobile phones.

6. Capacity expansion is a means that when a container or load is not enough to support or carry the demand of existing things, we can expand the capacity of the container or load to meet the growing demand, so as to relieve the pressure on the current container or load
at the beginning of the birth of bitcoin, Ben Cong, the founder of bitcoin, did not deliberately limit the block size. The maximum block size was 32MB, and the average block size was 1-2kb at that time
at that time, there are few bitcoin users and the transaction volume is not so large, which will not cause block congestion. However, since 2013, with the price of bitcoin rising sharply, there are more and more users, resulting in network congestion of bitcoin and rising transaction costs of users
up to now, there is a backlog of hundreds of thousands of transactions on the bitcoin blockchain. The average transaction cost of bitcoin is 376 times higher than that in September 2010. The processing speed of seven transactions per second has obviously been unable to meet the needs of users. The bitcoin community has begun to explore how to "expand the capacity" of bitcoin
by modifying the underlying code of bitcoin, the transaction processing capacity can be improved
there are two development and design schemes for bitcoin expansion, namely, the first layer and the second layer expansion technology
· the first layer of capacity expansion technology is to improve the blockchain itself, to make the blockchain itself faster and larger. Generally speaking, it is to change the content of the consensus part of the blockchain
· the purpose of the second layer expansion technology is to move the computing to the lower chain, that is, to solve the problem through the side chain technology
expansion protocol and outcome
expansion protocol generally needs the support of miners, which can be roughly divided into modifying block size, soft fork, hard fork, isolation witness and so on
take bitcoin as an example:
bitcoin is now divided into big block bitcoin cash (BCH) and isolation witness. Isolated witness is now recognized as bitcoin in the market, while big block coin is named bitcash. It can be predicted that in the future, bitcoin will focus on off chain trading. Including lightning network and side chain. These two new things are not mature at present, but they are highly expected by many people
bitcoin will develop a large number of isolated witness transactions and make more derivative technologies on the basis of isolated witness. Most likely, bitcoin will be pushed forward by technology
bitcash will focus on the development of monetary function, rece transaction friction as the main way, and gain more extensive users on the chain as the main development direction

8. According to the learning order, it will be more systematic and efficient:
(1) establish the outline understanding of blockchain through more popular reading materials
(2) get to know the elder: bitcoin
(3) learning: Ethereum and EOS
(4) learn several projects that you are interested in and have a thorough understanding of at least one project white paper
(5) expand learning through relevant media channels, and constantly enrich their own relevant knowledge
in the eyes of many newcomers, blockchain is almost equal to bitcoin, so it is necessary to understand the overview of blockchain first, just like taking a book and looking at the directory first to know what it contains, rather than reading the first page. After the first step of learning, we have a vague concept of bitcoin, blockchain, exchange and wallet. Hands on practice is the best way to improve learning motivation and efficiency. It can also put forward more practical questions in practice and find answers with questions. The learning effect will be better. Therefore:
(1) choose an exchange, such as: huobi.pro, okex.com, BIGone, otcbtc, etc., register an account. In this process, we need to pay attention to the use of Google verifier
(2) buy a little bit, such as 0.03 bitcoin. It is recommended to buy it through C2C OTC trading and usdt trading pair, and be familiar with the two ways of purchasing
(3) download and install wallets, such as Bitian, and pay attention to the storage of mnemonic words
(4) transfer a bit of bitcoin from the exchange to the wallet
after completing the operation of the above process, you will have personal experience of the exchange, wallet, private key, OTC trading, etc<
