Is it difficult for blockchain to find a job
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 carefula colleague of mine studied related technology in podcast before. Now the salary is higher than me
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 P>
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)
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 robustnesstrustworthiness: 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
blockchain technology is only a technical means of recording information, and its main characteristics are decentralization and transparency, which can be applied in any instry. The traditional mode of recording information needs the credit of the recorder to endorse it, and people have to pay for the credit cost. Compared with the traditional way of information recording, blockchain has unique advantages: everyone can record, and everyone has all the recorded information, which also means recing the cost of reputation. The so-called blockchain instry itself is a pseudo proposition, and technical means can be applied to any instry.
If an ordinary person doesn't work overtime, he or she will work seven to eight hours a day on average. If he or she works overtime, he or she will spend most of his or her life on his or her work. Therefore, choosing a good job that suits him or her is more important than finding a lovely person
When you find a good job, the time you spend is meaningfulno matter how hard it is to find a good job, you will also have a smile on your face
if you find a good job, your endless inspiration will be aroused
if you find a good job, your talents will be discovered by the world...
Tencent is the first one to launch. Crazy overtime and the latest technology are all here It is strictly forbidden to organize, there is a learning mechanism, and there is a requirement for the old to lead the new heroes
second Netease. Netease this company should be the national super will engage in marketing of the Internet company. You can go here later About 150 yuan per day)
the third Jinshan. Typical programmer company, but I suggest you enter Xishanju of Jinshan... I really don't know the internship salary of this company<
the intern positions in these units are generally recruited for a long time
don't fight for the position with the boss, keep a low profile, hold your thigh (the company's), and develop slowly
finally... Girls had better not be programmers
OK, if you like this answer, let's adopt it, or add my friends, private letter discussion
from Q users: Steven Chen & Chen 128081
Hello, I don't recommend you to do traditional java development. Two days ago, when I was recruiting for other positions, I asked CTO if she needed two years of experience as a female programmer (actually, she had no experience after the training, so I had acquaintances to ask for help). CTO gave me a smile and then went back to typing the code
this is the reality. However, when the programming class graated last year, all the three girls in the class found good jobs. It depends on you. If you think that women's strength is OK in the future, you can try it at that time. However, if you go to training for half a year after graation, it's very difficult to find a job in a month. Besides, it's almost difficult for a new year. No company is willing to recruit interns, Because interns can't make a living. A more formal company's resume doesn't have 3-5 years, so it doesn't give you an interview at all. If a company gives you an opportunity and wants you, it's also very likely that a company with about 20 employees will dismiss you before you become a full member
if you have some basic language skills, I suggest you try big data or data visualization. There is also python, which is not very saturated at present. There are not many companies that Python may use, and there are more financial or artificial intelligence companies.
recently, many of our customers are paying more and more attention to blockchain technology, Recently, I have found that this aspect has great potential for future development, and the talent gap may be relatively large in the near future. This is my suggestion. In a word, it's better to study, which will be helpful for future work. Six months of study is enough for you to consider your development. From Q user: Jason Jia
