Is blockchain a proper profession

1.

However, where are the opportunities for these innocent employees? To put it bluntly, some blockchain entrepreneurs are bent on "empty handed White Wolf", and exploit layer upon layer through "deception". Using asymmetric instry information, blockchain, digital currency and other projects are over packaged, giving people a sense of "Hope". This part of the blockchain entrepreneurs' inherent "bad root", to a certain extent, has led to the instry's "sick" development trend

some blockchain entrepreneurs call for embracing the times, changes and the future, emphasizing the charm of decentralized "fairness". But in reality, it is for self-interest, which hurts the interests of job seekers and other related groups, which is a great injustice in itself

The asymmetry of information is not permanent. Blockchain, digital currency and so on are all areas worthy of attention, but they are not the capital that can be used by some entrepreneurs as unlimited squanders all the time. For the job seekers who want to join them, they should polish their eyes, otherwise they may be surprised if they are not careful

The strict definition of blockchain refers to the distributed database technology that multiple nodes in peer-to-peer network jointly maintain a continuously growing list ledger constructed by time stamp and orderly record data blocks through consensus mechanism based on cryptography technology. This technical solution allows any number of nodes in the participating system to calculate and record all the information exchange data in the system in a period of time to a data block through cryptography algorithm, and generate the fingerprint of the data block for linking the next data block and checking. All participating nodes in the system jointly determine whether the record is true

blockchain is a technical solution similar to NoSQL (non relational database). It is not a specific technology, and can be implemented through many programming languages and architectures. There are many ways to realize blockchain, including pow (proof of work), POS (proof of stake), dpos (delegate proof of stake), etc

the concept of blockchain was first proposed in the paper "bitcoin: a peer-to-peer electronic cash system" by indivials (or groups) who call themselves Satoshi Nakamoto. Therefore, bitcoin can be regarded as the first application of blockchain in the field of financial payment

< H2 > [popular explanation]

no matter how big the system or how small the website is, there is a database behind it. So who will maintain this database? In general, who is responsible for the operation of the network or system, then who is responsible for the maintenance. If it is wechat database, it must be maintained by Tencent team, and Taobao database is maintained by Alibaba team. We must think that this way is natural, but blockchain technology is not

if we think of the database as a book, for example, Alipay is a typical account book. Any change of data is bookkeeping. We can think of database maintenance as a very simple way of accounting. In the world of blockchain, everyone in the blockchain system has the opportunity to participate in bookkeeping. The system will select the fastest and best bookkeeper in a period of time, maybe within ten seconds or ten minutes. The bookkeeper will record the changes of the database and the account book in a block. We can think of this block as a page. After the system confirms that the records are correct, the system will record the changes of the database and the account book in a block, It will link the fingerprint of the past account book to this paper, and then send this paper to everyone else in the whole system. Then, over and over again, the system will look for the next person with fast and good bookkeeping, and everyone else in the system will get a of the whole ledger. This means that everyone as like as two peas in the system is called Blockchain. It is also called distributed account technology. P>

as like as two peas (computer) have identical accounting books, and everyone has the same rights, they will not collapse e to the loss of contact or downtime of a single person. As like as two peas, the data is transparent and everyone can see what changes are in every account. Its very interesting feature is that the data can't be tampered with. Because the system will automatically compare, it will think that the same number of books with the largest number are real books, and a small number of books with different numbers are false books. In this case, it's meaningless for anyone to tamper with his own account book, because unless you can tamper with most nodes in the whole system. If there are only five or ten nodes in the whole system, it may be easy to do so. However, if there are tens of thousands or even hundreds of thousands of nodes and they are distributed in any corner of the Internet, unless someone can control most computers in the world, it is unlikely to tamper with such a large block chain

< H2 > [elements]

combined with the definition of blockchain, we think that we must have the following four elements to be called public blockchain technology. If we only have the first three elements, we will consider it as private blockchain Technology (private chain)

1, peer-to-peer network (power equivalence, physical point-to-point connection)

2, verifiable data structure (verifiable PKC system, non tampering database)

3, distributed consensus mechanism (Solving Byzantine general problem, solving double payment)

4 Game design of Nash equilibrium (cooperation is the strategy of evolutionary stability)

< H2 > [Characteristics]

combined with the definition of blockchain, blockchain will realize four main characteristics: decentralized, trustless, collective maintenance and reliable database. And the other two will be derived from the four characteristics  Features: open source  Privacy. If a system does not have these characteristics, it can not be regarded as an application based on blockchain technology

Decentralized: there is no centralized hardware or management organization in the whole network. The rights and obligations of any node are equal, and the damage or loss of any node will not affect the operation of the whole system. Therefore, it can also be considered that the blockchain system has excellent robustness

trustworthiness: there is no need to trust each other when participating in the data exchange between each node in the whole system. The operation rules of the whole system are open and transparent, and all data contents are also open. Therefore, within the specified rule range and time range of the system, nodes cannot and cannot cheat other nodes

collective maintenance: the data blocks in the system are maintained by all the nodes with maintenance function in the whole system, and these nodes with maintenance function can be participated by anyone

reliable database: the whole system will enable each participating node to obtain a of the complete database in the form of sub databases. Unless more than 51% of the nodes in the whole system can be controlled at the same time, the modification of the database on a single node is invalid, and the data content on other nodes cannot be affected. Therefore, the more nodes and computing power in the system, the higher the data security in the system

Open Source: since the operation rules of the whole system must be open and transparent, the whole system must be open source for the program

Privacy Protection: since there is no need to trust each other between nodes, there is no need to disclose the identity between nodes, and the privacy of each participating node in the system is protected

Well, I'm a blockchain operator

Yes, I am engaged in operation work in blockchain technology instry, covering community operation, user operation and content operation

is there any doubt that the blockchain technology is developing steadily, but the blockchain instry seems to be ups and downs? Blockchain operation is also exploring in constant changes. Me too

here is my confession

1.1. Not sad or happy, token is not all

operating in the blockchain instry, and the price is inevitable to talk about. Ups and downs are common, and ups and downs are daily. If you don't have a mind to see the strange, I'm afraid you can't bear such changes in the blockchain instry

2.2. Work or work, no change

what is operation? Compared with the early Internet instry, when most of the operations in the instry are still relatively shallow community operations, what we can do is to exceed the average level in the instry. Operation is still those operations, and because it is a blockchain instry, the nature of operation will change

3.3. Although it's exploration, there are also routines

in the process of operation in the blockchain instry, you will find that some operations still stay at the level of simple community operation or user operation, and even can't be called user operation, while some operations can be transformed from Zhonghua Li, upgrade and iterate their own operation routines, and have their own views on the development of the instry, We have explored our own methodology of blockchain operation

4.4. Professional level, top matching ability

what is professional? Ten points, twelve points. If the operation in the classical Internet era is traceable and the methodology of operation has a way to go, then the operation of the blockchain instry is based on the classical Internet operation. The changes in the blockchain instry are no less than those in the early years of the Internet, and even more than those in the early years of mobile Internet, o2o and other procts. What we need is not only the professional level of operation, but also the top allocation ability

5.5. To understand what you want to do

to enter the operation of the blockchain instry, most of you are interested in the infinite opportunities contained in this instry, or even directly cross-border from unrelated instries. No matter what your professional background is before you become a blockchain operator, I believe this instry will bring you what you want. But the question is, before you enter the instry, do you really want to understand what you want

6.6. Your core competitiveness and how to continue to advance

whether you operate in the classical Internet instry or in the blockchain instry, we must continue to explore, strengthen and continue to advance your core competitiveness. If you're good at it, dig deep. In the starting line and no big difference, the heart is the only key

the development of a new thing still needs to go through many detours, and the development of an emerging instry will also go through many key nodes

when eating crabs, you have to eat your own skills, don't you

5. 2016 is also the first year of the development of blockchain, and various VCs have invested billions of dollars into the start-up companies and projects of blockchain. Foreign IBM, Deloitte and Deutsche Bank have released their own blockchain designs. NASDAQ is already using blockchain technology. Securities, voting, data storage, logistics and other instries have appeared related applications
domestic first-line financial and Internet companies such as Wanxiang finance, LETV finance and Ping'an finance also joined the technological feast. Eurocrowdfunding and other micro enterprises are in the forefront of using blockchain technology.

6. Recently, the concept of blockchain has been very popular. Like the Internet in the 1990s, it promises to completely change our whole life, whether professional or personal. Just as the Internet spawned thousands of new companies in the early days, blockchain is now in a similar situation
as the backbone of emerging technologies, blockchain is not only used in the field of virtual currency, but also in other fields such as finance, medical care, intellectual property certification, etc. a large number of excellent enterprises have emerged at home and abroad to explore or enter the blockchain instry. Microsoft, IBM, Tencent, Ali, JP Morgan, Netease and Xiaomi have all laid out blockchain, and blockchain will blossom in many fields in the past two years
it can be seen that blockchain technology is developing rapidly in the world. Perhaps in the next few years, blockchain related technologies will be applied to the field of intelligence and notarization, including identity information authentication, notarization, arbitration, audit, e-mail, personal visa, ticketing information and so on. The application scope can cover the whole society, and blockchain technology is likely to become the lowest level protocol of Internet of things.
