Experience the decentralized communication software bitmessage

1. Absrtact: blockchain technology is the underlying technology of bitcoin. Without any centralized organization operation and management, bitcoin has been running very stably for many years (perfectly for seven years), and there has been no problem (no missing account). Therefore, some people have noticed its underlying technology and abstracted bitcoin technology, which is called blockchain technology, Or distributed ledger technology
what is centralization

the so-called centralization means "ownership" or ownership by the company. For example, Tencent's q-coin, which is issued by Tencent, is a kind of centralized electronic currency, including the total amount and the issuing method, is supervised and controlled by Tencent. You can use it, trade and go shopping, but you always have to operate in the framework of Tencent, and the final right of interpretation belongs to Tencent

the issuing mode of bitcoin is preset by the program and encryption algorithm, and runs on multiple nodes all over the world. No one or organization can modify it (everyone has his own account book, so it is impossible for one person to control everyone's account book at the same time. If there is such a technology, why should it be so complicated, If you want to blackmail money into your account, you will be the richest man in the world. There is no one left, And it is not controlled by any single person or organization
take an example: for example, Lao Zhang borrows 100 yuan from Lao Li, but Lao Li is afraid that he will default, so he asks the village head to do notarization and write down the account. This is called centralization. But if you don't find the village head, you can use the loudspeaker to shout in the village: "I Lao Li lent Lao Zhang 100 yuan! Please put it in the account book. "We all put this account in our own account book. This is called decentralization
anyone who transfers money between them will release information through loudspeakers. After receiving the information, everyone will record the transaction in their own account book. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma, Lao Wang and other families have ledgers

the main advantages of blockchain are that it does not need intermediary participation, the whole process is open and transparent, and the cost is low, and the data security is high

at present, blockchain is in a stage where everyone talks about blockchain, but can't perceive its actual technical charm. Since 2017, it has graally come into our sight, and we have graally realized that bitcoin is more fierce than real estate speculation (the price of mining machinery has skyrocketed! The news is on the screen But I still don't know

so, in which fields can blockchain be applied, what kind of changes will it bring to our future life

the core key: everyone has an account book, everyone has an account book, and the information recorded in each person's account book is consistent and synchronous, and the information is completely transparent. If it is fake, it will be the public enemy of the whole people, which greatly increases the cost of data fraud

core key 2: decentralization, which does not need a central system to manage data, prevents some people from changing data and damages the interests of the majority of people

Application:

1. Account security and privacy protection: currency transfer, exchange, payment system. Blockchain can help prevent data manipulation and fraud, prevent distributed denial of service attacks (DDoS), and effectively protect users' network privacy. Key words: anti counterfeiting, anti-counterfeiting, loan payment

2. Copyright regulation and interest disputes: for example, when a song is downloaded, from the author to the procer and then to the singer, they can get payment in real time through the blockchain, without having to wait for a long time like the traditional way, or even get no reward e to right disputes. Instead of waiting for publishers to provide royalty checks, creators can freely control the process from publishing to payment through blockchain application. Key words: real time receipt, no property dispute

3. Internet of things + artificial intelligence: the intelligent devices in the Internet of things based on the blockchain will be used to monitor the real-time situation of urban infrastructure such as bridges, roads, power grids, etc. the blockchain can connect these intelligent devices together for unified management to help them monitor more efficiently. This will help people better understand how to build a smart city in the future. Key words: unified monitoring, intelligent city

4: proof of existence: in life, once you are asked to prove that you are you, that your mother is your mother, that you have never been married, that the house belongs to you, and so on, things seem very simple. Once it falls on you, it is a great trouble. The application of blockchain technology can perfectly solve the above embarrassment. At that time, all the information that belongs to you will be recorded accurately and can not be tampered with. No one has the right to change it. When the technology develops to a certain stage, birth certificate and marriage certificate may be recorded on the blockchain. Keywords: no keywords

in addition to the application scenarios mentioned above, blockchain technology can also be applied to e-commerce, data storage, logistics and other fields. As long as we grasp the characteristics of blockchain technology, it will become easy to understand.

2. This is the best digital currency ranking to query, there are many third-party software support. Of course, if you want to choose a safe and reliable, decentralized exchange is a better choice.

3. Compared with centralized trading platform, what are the advantages and disadvantages of decentralized trading platform
since 2013, many decentralized trading platforms have emerged. Different from the centralized trading platform, the decentralized trading platform does not need to register an account, and can participate in the transaction by using the personal digital asset account
secondly, every transaction of the decentralized trading platform is carried out through the blockchain, and it needs to wait for the confirmation of the blockchain before the transaction is successful. At the same time, the decentralized trading platform is not responsible for keeping users' assets and private key information. On the one hand, it avoids the moral hazard of the trading platform, on the other hand, it requires you to keep your private key well
e to the low liquidity and slow transaction processing of decentralized trading platforms, the total transaction volume only accounts for 0.03% of the global total transaction volume of digital assets. At present, the tokens of airswap, kyber, 0x and omisego can be traded on huobi.pro.

Bitcoin is a kind of electronic currency / network virtual currency

bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods

on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency

from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees

extended data:

currency features:

1, decentralization: bitcoin is the first distributed virtual currency, the whole network is composed of users, and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom

2, global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3, exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

4, low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution

5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay

6, cross platform Mining: users can explore the computing power of different hardware on many platforms

advantages of bitcoin:

1, it is completely decentralized, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm

2, anonymity, tax exemption and supervision free

3, robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear

4, borderless and cross-border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records

5, Shanzhai people are difficult to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency

but these counterfeit currencies are very fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency

many counterfeit coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical

the weakness of bitcoin

1, the fragility of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities

2, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed

3, the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading

4, the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control

but the public doesn't understand, and many people can't even distinguish between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless

5. OK group's name has been changed to Oko, so it's impossible to completely decentralize, because the operation of complete decentralization can't be changed

6. fourteen trillion and nine hundred and forty-nine billion four hundred and nineteen million seven hundred and forty-nine thousand four hundred and seventy-nine

7. Now many organizations and institutions are studying the application of blockchain, but what kind of blockchain application is a good blockchain application? Let me sum up. If a successful blockchain application or decentralized application wants to be more universal, it should at least meet the following requirements. 1) As an excellent application, whether it is centralized or decentralized, it needs to have strong multi-user support capability. If decentralized applications want to be accepted by mainstream users, they must at least have the ability to support millions of people, so decentralized applications need to have enough capacity expansion. For example, the well-known applications such as Facebook, Uber and wechat must have the technology to handle tens of millions of daily active users, otherwise the application can't work normally, how can it be called an excellent application. The same is true for blockchain applications. The future application scenarios, whether payment transactions or social applications, need to have the ability to support a large number of users. It is very important to have a platform that can handle a large number of users. Now the number of users of blockchain applications is relatively small, so which application has strong scalability is an important part of future development. 2) Free application experience (users can not be forced to pay to use) the entire application platform or operating system, need to have the ability to support the application of this platform to develop free application software, need to provide a good user experience for users Even if there are many benefits of decentralized application services, users cannot be forced to pay for them.) Many times, application developers should flexibly provide free services to users. When users can use the platform without spending money, the number of applications developed on this platform is bound to grow. At the same time, the free block chain platform will naturally get more users' attention. When there are enough users, developers and related enterprises can create more profit models. 3) Simple and convenient system update capability (system update freedom and bug repair) the entire blockchain application and operation platform should provide enough freedom for participating developers. Update the decentralized application at the right time according to their ideas and needs If there is a bug in the application that needs to be solved, the developer should not affect the whole underlying operating system when repairing it. In addition, block chain based applications need to support software upgrade when they iterate. When the underlying platform of blockchain encounters a bug, it should have the ability to repair the error from the bug. 4) Low latency blockchain applications or decentralized applications should not only have the ability to run smoothly, but also have very low latency. For example, the speed of opening a website is very slow, and it takes several seconds. In this era of rapid consumption, users often have no patience to wait, at least it affects their mood and experience. The longer the delay time, the more user experience will be affected, and the decline of user experience will seriously affect and rece the market competitiveness of the application It's very easy to understand. If you open a web page very slowly, will you bother? 5) powerful serial performance. A good blockchain application should choose whether to focus more on serial capability or parallel capability according to specific application scenarios. For example, applications such as exchanges often need to handle a large number of serial operations. In this scenario, a good blockchain architecture needs to have strong serial performance, supplemented by intelligent parallel processing capability. Another example is that you need to transfer one purchase to another to avoid double spending. That is, if you take bitcoin and pay for things at the same time, one family may not receive money. Here is also to have a strong serial performance. 6) The intelligent parallel performance blockchain application operation platform should have the ability to make the decentralized applications based on it run synchronously, which can reasonably allocate the amount of computation and save time. Moreover, large-scale applications also need to divide the workload between multiple CPUs and computers
if you look at Aqua hydrogen oxygen project again, because its main website is not yet online, what I see here on the official website is more about the relationship between its investment and partners, and the noble background of the team. I believe in their strength, but when I investigate that Taotao class is also theirs, I want to ask how many people in this company have done a lot of things. But looking at the logic of doing things, I think there should be potential, but it will take time to verify

1、 New media is a form of digital media

includes all digital traditional media, network media, mobile media, digital TV, digital newspapers and magazines, etc

Second, new media operation mode

through modern mobile Internet means, through the use of wechat, microblog, post bar and other emerging media platform tools for proct publicity, promotion, proct marketing. Through the planning of brand related high-quality, highly communicable content and online activities, we can widely or accurately push messages to customers, improve participation and popularity, so as to make full use of fan economy and achieve corresponding marketing purposes

extended materials

new media can quickly absorb a large number of readers in a short time, which is far away from its grassroots characteristics, making "everyone is a news communicator" a reality

It is precisely because of this characteristic that new media has graally changed people's ideas and even their way of life. This new way has opened up a new field of society, stimulated the grass-roots groups who have been "silent", and awakened their desire to participate in the social process. This is also the most fundamental and important force for the rapid rise of new media and the promotion of social progress

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

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
