recommendation: this book is mainly for programmers. Combined with API programming, we can tell you the principle and usage of cryptocurrency, as well as how to develop related software. For non programmer readers, the first few chapters of this book are still applicable as in-depth introction of bitcoin Book pdf download: https://quant.la/Download

2. On the reasons why the etheric clown can succeed in blockchain games
etheric clown is a blockchain pet development game, which can easily make money. Make a real game to let players get a more comfortable experience, and combine with blockchain technology to ensure the interests of players. With the well-known proct form of game, we will spare no effort to promote blockchain technology and bring human beings into the era of full intelligence
we have repeatedly mentioned that blockchain is a decentralized system. Indeed, "decentralization" is a very important concept in the blockchain world. The design of many models (such as ledger maintenance, currency issuance, timestamp design, network maintenance, competition between nodes, etc.) depends on this central idea, So what is decentralization? Before we explain the real decentralization, let's have a brief understanding of what is centralization
centralization
recall the process of buying a book online:
first step, you place the order and pay the money to Alipay;
second step, Alipay will inform the seller that the seller can deliver the goods after receiving the payment.
third step, after the seller receives the Alipay notification, delivers the goods to you;
fourth step, after you receive the book, feel satisfied, choose to confirm receipt on Alipay;
fifth step, Alipay receives the notification, hits the seller to the money. The process is over
you will find that although you are dealing with the seller, all the key processes are dealing with Alipay. The advantage is that in case of any problems, sellers and buyers can seek help from Alipay and let Alipay make arbitration. This is the simplest transaction model based on centralized thinking. Its significant value is to establish authority, gain trust from multiple parties through authoritative endorsement, and ensure the reliability and security of data by relying on the capital and technical strength behind the authority
you are sure to put on a huge question mark face“ We can gain the trust of many parties through authoritative endorsement, and at the same time rely on the capital and technical strength behind the authoritative party to ensure the reliability and security of data
If Alipay's program has a significant BUG, resulting in the loss of the transfer records over a period of time, or more thoroughly, Alipay's server was destroyed by a missile from ISIS terrorist organization. And I just transferred out of the 100 yuan to whom to argue, at this time, you become a knife on the fish; Alipay has a conscience and will take the trouble to admit the fact that you have just transferred, but he does not admit that you are not, because he does not even know whether the transfer is real.
the above is the biggest drawback of centralization, that is, excessive reliance on the center and authority means graal loss of the right to speak
decentralization
what is the form of decentralization? Let's continue with the example just now. Let's build a minimalist decentralized trading system to see how we can buy a book from a seller we never know on the Internet
in the first step, you place an order and call the seller
the second step is to record the transfer information in your own account book
in the third step, you broadcast the transfer information
fourth step, seller and Alipay record their own accounts after receiving your transfer information.
in the fifth step, the seller delivers the goods and records the fact of delivery in his own account book
Step 6: the seller broadcasts this fact record
seventh steps, you and Alipay receive this fact record and record them on their own accounts.
Step 8, you receive the book. So far, the transaction process is over
the situation of "artificial fish for fish" is hard to happen in this system, because everyone has a completely identical transaction record on the books. Alipay's account server is broken. Sorry, seller's account still exists, and my account still exists. These are hard evidence that the deal really happened

of course, in this minimalist trading system, you have found many loopholes and misunderstandings. For example, one of the three parties is a villain who intentionally records the transfer information that is more beneficial to him; Another example is how to deal with the message tampered by hackers in the process of transmission. This may have been mentioned in the previous introction to computer or computer network books, such as "quasi two armies" and "Byzantine Generals". I'm not going to repeat it here, because it's not related to the main line for the time being. Interested students can go to Google or the Internet. You just need to know that in the blockchain system we're going to talk about next, smart design is enough to solve the above-mentioned bugs
the ether clown can be so hot only when he understands these!
3. Fatbook decentralized library, originated in 2012, named "life is one fat book", comes from Shenzhen University. Idle books will be presented to the public, and legal books will be transferred through giving, exchanging and lending. Everyone's bookshelf is everyone's bookshelf, everyone's book is everyone's book, and everyone is a librarian
according to the agreement, as long as the permanent ownership of books shared in fatbook is this platform, and users only have temporary ownership of books, the circulation of books is the circulation of temporary ownership. With the increase of users, the technology becomes more and more mature
fatbook obviously uses blockchain technology. The first one is decentralization, or multi centralization. Everyone is a point and can be managed in a distributed way
another thing is that everyone has the same authority. Everyone can borrow and lend. At the same time, everyone can't operate other people's "bookshelves". They have the same rights.

if you want to systematically understand the operation and management of an enterprise, it is recommended that you read the whole series of 12reads books. Although 12reads books can only be purchased from the official library, and the price is higher than ordinary traditional books, if you want to know the relevant professional knowledge, it will be a good self investment

{rrrrrrr}

please click to input the picture description

the so-called event technique is how we land on things. To promote the development of the company, you need to organize something rhythmic, three months, a month, or a few days as a rhythm

Moreover, the most important thing in rhythm is that you should have a closed loop, and the core is three axes:

1. Strategy finalization

in the past, we focused on strategy, but now we all think that the competition of enterprises is boundless, and we should continue to extend the chain of users

there is no right or wrong, but the strategy must be finalized

2. Organizational support

there are two organizational modes:

closed loop. For example, the original meituan group buying, whether it's wine travel or take out, is a small business unit from proct development to BD, and this business unit has all the resources to do this

China Taiwan chemical. It is to organize all the back-end reusable resources with the middle platform. If the business is sales oriented, it is organized by sales oriented people

if the user experience is biased, it is organized by the operators, but the back-end data platform and commodity library will be at the bottom and become a big platform. Which form of organization is better

it all depends on the competitive situation of the instry. If the requirement for fast running is very high, I think the closed-loop is worth it. But if it reaches a certain level, for example, when three into two and two into one, the form of middle platform is more concive to group operations

3. System escort

the key of system is reward and punishment. We have come all the way from Ali, and we deeply understand that an enterprise organization is 271: 20% of the people are top, 10% of the people must be mediocre, and 70% of the people have seven ups and seven downs, some of them may be qualified, and some of them may be unqualified

If an enterprise does not have very good rewards and punishments to make those excellent people feel that I should do better and let those unqualified people be eliminated graally, your previous strategy finalization and organizational security are nonsense

summary: how can a person become a success

my conclusion is just four words: potential and success. If this runway is originally a very flat potential energy, you can either go in small or it is basically very difficult. Therefore, you should be familiar with the overall economic context of China, the rules of entrepreneurship between China and the United States, China and the world, and the turning point of this instry. These judgments are crucial

in addition, the success of an enterprise depends on people in the end, and it is decided by 10% and 20% people to a large extent

the competition between enterprises is not simply the competition of execution, but the competition of thinking and understanding ability

5. What I trust more is the coin letter wallet. Since 17 years ago, I have been trading bitcoin on it. Risk control has done very well and never had any problems. Moreover, there are many kinds of digital currencies available on it.
6. How to realize blockchain? The current situation of global blockchain development is also more and more enthusiastic, which shows that blockchain is widely used all over the world, has more and more powerful vitality, and affects all walks of life from the outside to the inside. The current situation of global blockchain development has a very good atmosphere, which is inseparable from the active support of various countries, and is also related to the increasing public attention of blockchain technology

blockchain has a deep origin with bitcoin (in fact, bitcoin is the application of blockchain Technology). Is it a signal released by the central bank? I don't know for the moment. After all, the central bank is now the most credible third party, and the development of digital currency with blockchain technology has the taste of breaking its own path. Bubi blockchain focuses on the innovation of blockchain technology and procts, has a number of core technologies, and has developed its own blockchain service platform. With decentralized trust as the core, we are committed to building an open value circulation network to let digital assets flow freely

who will benefit from the concept of blockchain technology

in which field will blockchain technology be applied first? There is no doubt that blockchain technology will first be applied to the financial system with the highest requirements for security, openness and stability. Let's take a brief inventory of the application scenarios of blockchain in the financial system: issuance and circulation of digital currency, information disclosure and share management of private and public funds, trading system of financial derivatives, transaction records, consumption records, personal lending, small and micro finance, electronic contract, etc. From the perspective of application, Bubi blockchain has been applied to equity, supply chain, points and other fields, and is concting experiments and application tests with exchanges and banks. Bubi blockchain focuses on the innovation of blockchain technology and procts, has a number of core technologies, and has developed its own blockchain service platform. Moreover, many blockchain innovation and entrepreneurship enterprises continue to emerge

for example, the securities exchange market may be the most suitable mole for blockchain in the financial field. Traditional securities trading needs the coordination of banks, securities dealers, exchanges, and central settlement institutions to complete a stock transaction, while blockchain system can independently complete a full set of behaviors: through the digital certificate containing the user's basic information, the user signs the content of the certificate with his own private key, and all the user has to do is press the operation button, And can real-time query whether someone tampered with the content of the certificate. It's not imaginary. In fact, they did. In 2015, NASDAQ Stock Exchange and London Stock Exchange, the world's top four exchanges, have explored the application of blockchain

therefore, software service providers serving the financial system are destined to be the direct beneficiaries of the blockchain concept, unless the application of blockchain technology is a false proposition. Now look at the blockchain technology, it has been initially applied, but the market space is too large for us to measure

chain open standard has been supporting a number of blockchain projects of leading financial companies, which can promote the requirements of open standard through in-depth cooperation with chain as early as 2014. For the first time today, this standard is open to the wider financial sector. The chain open standard is built for specific purposes. It can support large-scale financial applications and meet the strict regulatory, security and privacy requirements of the financial services instry while running the licensed blockchain network<

the chain open standard achieves breakthroughs in the following aspects:
the new consensus model realizes the final completion of the transaction in less than a second, even if the transaction volume is very large
the privacy solution encrypts the blockchain data and allows the relevant counterparties and regulators to read selectively
smart contract framework and virtual machine support simple rule execution and Turing complete program for key value storage
scalable data model can rece the running load for network participants

how to realize blockchain? The current situation of global blockchain development also shows a good prospect of blockchain technology. This trend of comprehensive application will be shown in various fields of various countries.
7. As for time management, I advocate teacher Li Xiaolai's "making friends with time", because his book fundamentally answers us how to manage time, which is the most effective

the picture is from the short book app

for example, this book holds that if we are on the wrong path, the more careful we manage our time, the more distant it will be for us to achieve our goals
moreover, when it comes to time management, we should first put our mind in the right place
for example, if we recite English words with a loving attitude, we will definitely be better than those who don't like to memorize words, even if they do a good job in time management, how many words to memorize in that time period and do exercises in that time period
he also mentioned a point in his book, that is, our brains are easy to forget unpleasant things. So if you take learning English as an unpleasant thing, how can you learn English well
if we don't solve the fundamental problems, it will be very difficult for us to do a good job, which may backfire

I recommend Schopenhauer's essays on Schopenhauer's Thoughts on self cognition and the evolution of thoughts<

the pictures are from the short book app

in this book, what he most praises is about the control of desire over people and the subtle relationship between desire and intelligence
moreover, he also has his own profound views on ecation, genius and sex
in the 14th century, he had such an idea, which is enough to prove his greatness
what attracts me most about this book is that he is able to explain a point of view thoroughly, and his point of view is also very novel and specific. This may be because he is a foreigner Anyway, the books I read recently are all written by foreigners, and there are many arguments, such as "different", "influence" and so on
for example, on ecation, he talked about intuitive cognitive learning and conceptual learning thoroughly. And in his book, he often criticizes the harmfulness of concept learning in modern ecation
his view on ecation is also very clear, that is, at the beginning of learning, people should let intuitive cognition precede our conceptual learning. But our present ecation has reversed this order
the result of this kind of ecation is that people lose their judgment, and there will be a phenomenon that the society does not adapt to the society
this point of view can well explain the phenomenon of the disconnection between ecation and society
therefore, this book should be expected for you

influence is a book that anyone can read, whether it's a seller, a teacher, a doctor, or other professions<

the pictures are from the short book app

this book is mainly about how to get along with people, how to sell yourself, and other tips of life and work
for example, the principle of reciprocity in interpersonal communication
if we apply this principle to our life, it will greatly improve our interpersonal relationship and enhance our social skills
in the work of our salesmen, we use this principle very thoroughly
for example, give customers some unexpected benefits, bring them some special procts, and some value-added services
this greatly increases the number of transactions between customers and us, and further improves our sales
the principle of "consistency" in books is also very thorough
the principle of "consistency" literally means that people will keep consistency before and after doing things. This is reflected in the view of consistency, the choice of consistency, the goal of consistency and so on
this is also like a favorite saying of ordinary people: "you have to finish the road you choose when you kneel down."“ Consistency "is the truth
therefore, the influence of this book is not only in our work, but also in other aspects
therefore, if we want to influence our friends through "influence", we can get the answers we want through this book
4
everyone must know something about it, because the principle of "10000 hours" in this book is known to all: if a person wants to be an expert in an instry, he must work at least 10000 hours in this instry. According to the way that we work eight hours a day and five days a week, if we want to become experts, we have to settle down in this instry for at least ten years

the pictures are from the short book app

it is precisely because of this book that I find what I want to stick to
it is precisely because of this book that I am not so impetuous, but more able to persist and have patience to do something
it's also because of this book that I really understand the state of those excellent people who are achieved only by persistence
therefore, no matter what I look like now, I know how to stick to my work and do something I like. I believe I will make a difference.
8. Zhihu and Douban have many recommendations. Let me share with you some of my accumulation
Literature: Wu Hu Lu (by flame tower), Lao Can's travels, Walden lake, plague, Xiao Wu Yi (with teacher Shan Tian Fang's Commentary), gone with the wind, Muxin series, memories of Muxin, the past of Su Lu, chrysanthemum fragrance, salt, pain, six chapters of floating life, Xiang Ji Xuan Zhi, the 15th year of Wanli, etc The stories of Ming Dynasty, intimate relationship (written by Christopher), story of art, singing of mountains, Stoner, introction of hengshijie, buried giant, pilgrimage of one person, Liu Cixin's three bodies (really recommended), Muslim funeral, one hundred years of solitude, complete works of Wang Yangming, besieged city, etc
I would like to recommend the following online articles about flowers: Tang Qi series "four act drama", book haicangsheng's "Zhaoxi old grass" (I may not understand it for the first time, but I will never forget it after I understand it) and "ten years I have tasted Wen Ruyan", now where is "the legend of Wukong" and "Nuo Xinghan sky"
I recommend these books for the time being, and I will share them later when I come across some good books. I hope you can adopt them.
9. The first reason for selecting the book of links
it's a long time since the book was finished, but now it's not outdated to read everything about complex networks in this book. Nodes are always competing for links, because connecting in the Internet world represents survival. You may also understand entrepreneurship as a story of how to turn yourself into a hub node as much as possible in the complex network world
extending from biology and nature, cell is a real small world with similar topology to other abiotic networks; The high fault tolerance of ecosystem is guaranteed by the highly interconnected complex network, and the robustness of the whole system is enhanced by the interconnection of nature; Since its birth, the Internet has been following the classic model of growth network, with exponential growth and no sign of slowing down. It has evolved into more and more distributed, decentralized and localized. Today, data and connectivity are becoming more and more complex and important. The complexity thinking proposed by Barra Brazil reveals the secrets of artificial intelligence and big data from the bottom logic, and it will become more and more important
we don't live in a random world. There must be some order behind the complex system
many points first proposed in the book are worth repeating:
complexity ≠ randomness
hub node is the result of power law, which is the symbol of self-organization and order
growth mechanism (first come, first served) and preference link (the strong is stronger) are the two laws governing the real network, and fitness, as a new star effect, can dominate everything, making and breaking hub nodes
the start-up companies born in the business model of the new network economy will bring about changes in wealth and resource rights
the second reason for selecting scale is also a book about complex networks, but it uses a grand narrative structure, spanning biology, physics and sociology, to get through the laws of biological growth, evolution and social evolution. It is full of insight and interesting analysis. The tiny indivial evolution system is closely related to the huge city, society and society To some extent, there are similarities in the national evolutionary system. If we examine evolution on a scale, we will see more truth about the world. After reading the book, I can't finish it
at the end of the book, there is a special chapter on company operation and governance. Small, young companies grow rapidly, while mature large companies grow slowly. No matter organisms, companies or society, how to continuously provide more energy for growth, innovation, maintenance and repair to fight against entropy has become the basis of any serious discussion about aging, death, system resilience and sustainable development. Only by continuous innovation can we live forever. I believe this book will inspire the management of fast-growing start-ups
the third reason for selecting the book speculation and position
the social environment is changing rapidly, and the complexity of daily problems is increasing. Our cognitive level and decision-making level have a greater and greater impact on the quality of work and life
critical thinking is the thinking ability to help people better understand and identify problems, improve decision-making, and continuously improve their thinking level
the authors of this book, Richard Paul and Linda elder, are the authorities of critical thinking. This book not only talks about the basic principles of critical thinking, but also provides practical tools and methods to improve the level of thinking. This book may help you in the following aspects:
build awareness and distinguish good and bad thinking habits
build awareness and distinguish good knowledge from bad knowledge: is it rigid and invalid knowledge, long-term use of fallacious knowledge or can continue to bring more effective knowledge to the real understanding
distinguish different information: how to treat the authenticity of information, how to identify the interest relationship between information and information sources, and how to distinguish logical inference and default assumption
think about different views: get rid of self bias, accept opposite views, and form the ability to think within and between views< At the same time, it also helps people form the ability to reflect on their own thinking, so that their thinking can be snowballed and improved
recommended reading. After reading, it is also suitable to keep it at hand and accompany yourself to develop the habit of thinking improvement
