❶ How much does it cost to develop a blockchain wallet application

It also depends on what kind of blockchain APP you are developing. It may cost several thousand yuan. It can be done, and the complex ones may cost tens of thousands, hundreds of thousands or even hundreds of thousands

❷ How to do blockchain enter

Blockchain technology is currently developing at a high speed In the past two years, our country has also invested a lot of money and cultivated talents in this area.
Technical people who are born can learn this technology, and non-technical people can start from industry media and industry communities.
If an enterprise needs to develop blockchain applications, it can entrust a professional third-party company. The current technology in Guangzhou is good.

❸ How to quickly get started with blockchain

Currently, there are not many videos on the market for systematically learning blockchain, and it is still relatively rare to learn blockchain by yourself. You can sign up for a class. Dark Horse Programmers has newly opened a blockchain course. The teacher uses easy-to-understand teaching methods and explains the technology in simple and easy-to-understand terms. You can definitely learn it. Source: AreaTV. If you want to understand blockchain and watch video tutorials, come here!

❹ How much does it cost to develop a blockchain application

It mainly depends on the functions of the blockchain application app. For example, Startup Technology calculates the development cost of the blockchain based on its functions. If there are many functions and high complexity, the corresponding cost will be relatively high. If the functions are simple, the price will naturally be very low.
Whether it is a blockchain wallet, a blockchain exchange, a blockchain pet game, or a blockchain points mall, prices are estimated in this way.
The cost of this development is mainly calculated by labor cost and hardware consumption cost, plus some marketing expenses, and the price can almost be determined.
In some cases, the price of the app will be very low, that is, there is ready-made source code that can meet the needs of customers, and it only needs to be modified and added with some functions before it can be used.

❺ How to switch careers and enter the blockchain industry in 2020

As a technology worker and a computer professional educator, let me answer this question.

First of all, with the development of the industrial Internet in 2020, blockchain will have more application scenarios, and blockchain technology will also play a more important role in the application process of the industrial Internet. positive effect. From this perspective, the blockchain field will also become a hot area for innovation and entrepreneurship in the future.

For ordinary entrepreneurs, if they want to enter the blockchain field to start a business, they can find an entry point based on their own industry resource integration capabilities. For the majority of small and medium-sized entrepreneurs, entering the blockchain field should make industry innovative applications on existing blockchain platforms. This will not only greatly reduce the threshold for innovation and entrepreneurship, but also provide a certain foundation for practical applications. As many large technology companies are deploying in the blockchain field, there will be more foundations in the blockchain field in the future.Application models for specific industries, and small and medium-sized entrepreneurs joining these ecological models will make the entrepreneurial process easier.

Innovation in the blockchain field must be fully integrated with the current background of industrial structure upgrading. This process requires entrepreneurs to have a certain ability to integrate technical resources, and at the same time have relevant knowledge in the industry. After a certain amount of accumulation, blockchain innovation in the industry must be inseparable from the participation of industry experts. Since there are a lot of innovations in the industry, the application prospects of blockchain are still very broad.

The innovation of blockchain technology can also be combined with current cloud computing, big data and Internet of Things technologies. Taking the field of big data as an example, blockchain technology can solve the problems of big data to a certain extent. Security issues, which also provide a certain security guarantee for the implementation of big data. With the continuous implementation of industrial Internet-related technologies, the application scenarios of blockchain will gradually improve.

Finally, entrepreneurs with strong resource integration capabilities can also consider building their own blockchain platform.

If you have questions about the Internet, big data, artificial intelligence, etc., or about postgraduate entrance examinations, you can leave a message in the comment area, or message me privately!

1. Self-study blockchain knowledge

Basic knowledge before entering the industry is essential.

Blockchain is an interdisciplinary subject. The disciplines it includes are mainly finance and computer science, followed by information science, economics, psychology, quantum mechanics, and cryptography. , sociology, etc., the knowledge system is quite complex. At the same time, as an emerging thing, there are dazzling related materials on the Internet, but its knowledge system construction and science popularization work are still very imperfect. It is difficult for beginners to find comprehensive and easy-to-understand materials for learning.

2. Understand the recruitment supply and demand situation in the blockchain industry

The demand for blockchain recruitment is concentrated in first-tier and new first-tier cities, and most of them are concentrated in Beijing, Shanghai and Shenzhen, so go Beijing, Shanghai and Shenzhen have the largest number of job opportunities, and the job supply is mainly technical and sales positions.

The existing blockchain talents are gathered in Beijing. Most of them are senior professionals in the workplace, and half of them have more than 5 years of work experience. Their academic qualifications are generally high, and most of them have a bachelor's degree or above, so they are recruiting now. The required academic qualifications generally require a bachelor's degree or above.

Data as of 2018 show that there are approximately 388 start-up projects in my country’s blockchain industry, mainly distributed in the fields of finance and blockchain platforms. Among them, financial projects account for 42.3%, and blockchain projects account for 42.3%. About 39.2% of the platform. Most of the existing talents in the blockchain industry are from the Internet industry and the financial industry. Therefore, the industry’s professional background requirements for graduates are alsoPriority is given to IT majors and finance majors.

83% of the investment received by blockchain companies is concentrated in the early stage (A round and before), and the companies recruiting are mainly small and medium-sized enterprises, that is, companies with less than 100 people, and 20-99 The number of people reaches 43%.

3. Go out more and participate in industry activities

It is very important to accumulate work experience during workday internships. At the same time, go out and participate in industry activities more often in the evenings and weekends. , it is also particularly important to make connections.

Because on the premise of having certain corresponding work experience, the key to successful social recruitment is to get referrals from personal connections and get to know the employees within a certain company. Then when their company has recruitment needs, you can It can be obtained immediately, and coupled with the credit endorsement of this relationship, it can greatly improve the efficiency of social recruitment and job hunting.

The best way to get to know industry contacts is to participate in internal industry events. Beijing, Shanghai and Shenzhen are the centers of blockchain industry resources. There are many industry events held every month, many of which are There is no threshold, it is free and you can register directly to participate.

Do you understand blockchain?

Blockchain is an emerging industry, and it is said to be a good thing in itself. But if everyone pours into it, I think if this continues, the cake may not be enough. There are also some people who have done bad things in the name of blockchain, so I personally think that if you are a layman, you should not go in to avoid suffering

What is blockchain? Are people from the same community shooting Douyin short videos together? [face covering]

Blockchain is a consortium of big guys. People who are new to the logistics industry should wait and see first and don’t touch it

Blockchain is an industry ? [Yeah][Yeah][Yeah][Yeah]

Blockchain is something that only high-end people can play with, and most ordinary people will make no progress

Blockchain, hum, there is no free lunch in the world, there are many victims around me

Blindly following the trend, decentralized technology is not suitable for all industries, and there is not such a large demand for technical talents. This concept Put it forward, many people do blockchain without even knowing what blockchain is. It is better to learn more about the application scenarios of blockchain and then study the transformation.

❻ Newbies investing in digital currencies (Blockchain) Getting Started Guide, just read this article

Blockchain and digital currency investment have a higher entry barrier than other investment methods. Many friends want to invest in digital currency but don’t know where to start. Where to start, I don’t know what to learn. Although 51Coins has updated a lot of relevant knowledge in the "Beginner Playing Coins" section, it is not systematic enough

ThisThis time we will systematically organize and summarize the information related to blockchain and digital currency investment, so that everyone can understand and invest in digital currency faster and more conveniently

1. Understand blockchain and digital currency

No matter what you invest in, you must understand it, and the same is true for blockchain and digital currency. There are many introductions about blockchain on the Internet, some are too profound, and some are not comprehensive enough. I personally think the video "100 Questions on Blockchain" produced by Huobi is better

100 videos , all of which are blockchain-related knowledge, including: the birth of Bitcoin, operating principles, blockchain FAQs, mining, wallet introduction, etc., and are all in the form of animated videos, making it easier for everyone to understand. Although the explanation is not detailed enough, it can give you a preliminary understanding of digital currency and blockchain

2. Choose a trading platform

After understanding digital currency, you can try to use the trading platform Purchase a small amount of digital currency and experience the process. The purchase and sale of digital currencies must be completed through a trading platform, which is equivalent to a stock exchange in the stock market. It is recommended to choose a large trading platform for the trading platform, which has a comprehensive range of currencies, convenient transactions, and guaranteed fund security

The following three platforms are recommended: Binance, Huobi, and OKEX (ranked in no particular order)

< p> 3. Choose a wallet

If digital currency is compared to cash, a wallet is equivalent to a bank card, used to store digital currency. There are many types of wallets, and the most commonly used ones now are mobile APP wallets (light wallets). Wallets are also divided into types. Different similar digital currencies cannot be transferred to the same wallet. For example, if imtoken is an Ethereum wallet, it can only store Ethereum and tokens issued based on Ethereum, but not other currencies

< p> There are also wallets that claim to support all digital currencies, but most of these wallets are not yet complete.

Of course, after we buy digital currency, we don’t need to deposit it in the wallet, but directly put it in the exchange account, which can save the handling fee and not be so troublesome. Large exchanges such as Huobi and OKEX are relatively It is safe. I personally basically put digital currencies on exchanges

4. Determine the investment plan

Before investing in digital currencies, we must first determine our investment plan and plan to invest. How much money, how much loss you can accept, what is the expected return, and how long the investment time frame is, determine it before investing. Digital currency is a high-risk, high-yield investment product. In the novice stage, you can invest only your spare money that does not affect your life. There is no limit on the amount of investment, and the minimum investment is a few hundred yuan.

Wait until you truly understand the market before making the appropriate investment. Increase the investment amount, but remember to keep the investment amount within your tolerance

5. Select the investment currency

After selecting the trading platform and confirming the investment plan, you can purchase Digital currency, there are so manyWhich digital currency should we buy? When buying coins for the first time, it is recommended to choose mainstream coins. You can choose a few coins that you like among the top 20 in the market or recognized value coins

Find out what these coins are for and whether they are available What is the actual value, what news has recently affected the currency price trend, etc.

Understand these issues before buying, and be sure to pay attention to the purchase price before buying

6. Common tools, Website

1. Non-small account: You can view information related to each currency and exchange, including currency price, historical price, increase and decrease, circulation volume, ranking and other information

2 , AICoin: The function is similar to that of non-small accounts. The K-line of aicoin is very convenient and easy to use. It is the first choice for watching K-line charts

3. Coin World: Real-time updates of news and information related to various blockchains and digital currencies

4. Golden Finance: A relatively comprehensive blockchain media platform, including news, news, quotes, celebrity columns, etc.

7. Learn more relevant knowledge

< p> With the above 6 points as a basis, even if we have initially learned about digital currency investment, we still need to learn more knowledge if we want to truly make money by investing in digital currencies. The two most important points are to deepen the understanding of the blockchain and technical analysis (K line)

These two are too broad and cannot be learned overnight, so I will not introduce them, K You can find a lot of online knowledge online. As we invest longer, understand more currencies, and come into contact with more related matters, we will gradually deepen our understanding of blockchain.

❼ What is blockchain in general? How do people make money in the blockchain?

The popularity of blockchain has caught the masses off guard. Nowadays, no one knows about blockchain, but many people do not have a clear understanding of the definition of blockchain.

So, what exactly is blockchain?

Regarding blockchain and Bitcoin, most people have this misunderstanding: Bitcoin is blockchain.

In fact, Bitcoin and blockchain are not the same thing. Blockchain is the underlying technology of Bitcoin, but the first usage scenario after the birth of blockchain is Bitcoin.

I will explain to you what Bitcoin is and what blockchain is. Please move your bench quickly!

What is Bitcoin?

Bitcoin is a digital currency, a peer-to-peer encrypted digital currency. It is not a tangible paper currency such as RMB or US dollars. It is generated by computers through specific mathematical calculations. Also stored in the computer.

Because Bitcoin is just a string of data in a computer, it is also called a "virtual currency" compared to paper currency. Simply put, you can understand it as BitcoinIt's just a string of numbers with cash value, similar to Q coins. In other words, Bitcoin has no actual value. Its current value is supported by the faith of currency speculators. If the faith is gone, the value of Bitcoin will collapse.

Bitcoin is magical, what is its magic?

If you want to get Bitcoin, in addition to buying it, you can also mine it. The original Bitcoin is mined!

1) Mining

The first thing that comes to mind for many people is the image of a coal mine:

Mine, absenteeism, dust , black coal, large trucks.

Bitcoin mines are not like this. They only need electricity, network cables, and computers. However, mining this mine is a technical job, and it tests the performance of the computer's CPU and GPU.

2) Transaction

How does a Bitcoin transaction proceed?

Each user has a unique address, which is the Bitcoin "wallet". For every transaction, for example: A pays B a Bitcoin, a Weibo post will be posted publicly in the system saying: "I gave B a Bitcoin @B". These records will be kept as evidence at every terminal of the system. on the chain.

If A wants to go back on his word and tamper with Bitcoin’s transaction history, then every terminal record on the network must be modified. However, this is not easy, because only A whose computing power exceeds the sum of the computing power of all nodes in the system can tamper with transaction records. Obviously, this is unrealistic.

In the transaction process, Bitcoin uses a decentralized accounting method, which is also blockchain technology. Simply put, blockchain is a decentralized distributed ledger database.

What is blockchain?

The blockchain was created along with Bitcoin. During the formation of Bitcoin, blocks were storage units one by one, recording the communication information of each block node. Blocks are very similar to For database records, every time data is written, a block is created. With the expansion of information exchange, one block continues with another, and the result is called a blockchain.

Blockchain is a distributed ledger technology. Everyone participates in accounting, and everyone has a copy of the ledger information. This account book is not easy to forge and is traceable.

For example:

On a certain day of a certain year, Lao Wang lent Xiao Wang 10,000 yuan. Lao Wang told everyone around him the news , the transfer records were posted on WeChat Moments, and everyone helped them testify to the existence of this transaction.

Lao Wang and Xiao Wang are two nodes. These two nodes generate transaction time, location, person and other information, and package themto form a "block". Lao Wang’s friends are also nodes. These nodes jointly record the transaction status and details (blocks) of the two nodes Lao Wang and Xiao Wang. These blocks are connected to form a chain, forming a decentralized database.

In the past, only both parties knew when Lao Wang and Xiao Wang borrowed money. This was the centralized accounting model. But now everyone knows it and records it in their own ledgers. This is the decentralized accounting model. model.

When one day, Xiao Wang regrets that he did not borrow the money, everyone around him will know their transaction information, so Xiao Wang will not be able to deny it. This is the blockchain Information sharing cannot be tampered with.

How do ordinary people make money by participating in the blockchain?

I have summarized several methods suitable for ordinary people to make money during the blockchain bonus period.

1. Direct investment in blockchain: buy coins or buy some blockchain stocks, but the currency circle is risky, so you must be cautious when buying, and there are many blockchain stocks now. However, there are risks in the stock market, so investment needs to be cautious.

2. Make blockchain self-media: run a WeChat public account or Toutiao account, write articles about blockchain and publish them on it. If you are good, you can also get some good profits.

3. Participate in technology development: In fact, it is very simple, it is to participate in the process of blockchain development. However, this method requires high technical threshold.

4. Blockchain training: Companies that can provide blockchain technology training or knowledge training.

That’s all the relevant knowledge about what blockchain is, I hope it can bring you some help.

❽The reason why blockchain talents cannot be found even with an annual salary of 5 million

Recently, a blockchain recruitment advertisement in Beijing went viral on WeChat Moments, asking applicants to be familiar with blockchain technology. Those who have in-depth research on cryptography will be offered an annual salary of not less than RMB 5 million, with no upper limit.

Song Mofei told reporters that in the actual development process, simply mastering the use of some blockchain tools is far from enough, because blockchain is inefficient and scalable. There are still many problems in terms of security, etc., which requires developers to improve the underlying platform of the blockchain to meet the needs of practical applications. Blockchain technology integrates cryptography, computer networks and game theory, and is a typical composite discipline. Mastering and understanding the underlying technology of blockchain does not happen overnight.

In the view of Shan Yi, chief data officer of Liepin.com, the core of blockchain is a change in social relations and business models based on the Internet's distributed trust system, and this change is based on decentralization. are typical characteristics. “There are still many uncertainties in the future development of blockchain. There is currently an obvious bubble. Many blockchain projects do not rely onSpectrum. ” he said.

❾ Is the blockchain major an unpopular major?

Yes

1. What is blockchain

Blockchain is a new type of Internet technology. Simply put, it is a decentralized distributed ledger. It relies on the underlying cryptography foundation and is a completely transparent operating rule established on the Lucky Network. Currently, there are many problems in society. The engineers who lack this category are mainly engaged in technology. For now, I am very optimistic about the development prospects. From the perspective of academic research, this kind of advanced thinking can also be learned and used for reference. In the future, we may be able to solve problems. There are fewer practical problems, such as financial mechanisms, privacy issues, etc. The technical threshold for learning blockchain is higher than that of other Internet technologies. When the trend becomes bigger, more people will naturally rush to it. Moreover, it is still a relatively small minority. Yes, the main language to learn is Go. In addition, you need to learn more mathematical knowledge, algorithms, cryptography, etc., which is relatively difficult. Of course, the salary when looking for a job will be relatively good, and the ability and reward are They are all directly proportional. Moreover, two of the nine newly added occupations this year include the blockchain industry, which shows that this industry is attracting more and more attention.

However, the banking and finance industry does not require a complete transformation of processes adopting blockchain technology, and financial institutions are beginning to consider applying blockchain to traditional banking operations. In addition, the Australian Securities Exchange The institute is planning to use a new blockchain-based system to manage the Australian financial market by the end of 2020.

Once again, blockchain will be integrated into government agencies in the future, and the Estonian government has taken the lead in implementing it at the government level, which can Contains information about all residents and citizens.

In the future, the demand for blockchain experts will grow rapidly, especially blockchain engineers and experts who already have relevant experience. Although it is possible that you enter Start-ups will withdraw capital and go bankrupt because the technology is immature or investors are dissatisfied, but blockchain is still a high-demand industry in the future.

Judging from the fact that the world is now starting to recruit talents, such as Australia's Global Talent In the project, Fintech has become an important field among the seven fields they need, and so far, both the number of people who have applied and the number of people invited are the smallest, because this industry is still relatively new in many countries. Compared with other fields such as agricultural technology, advanced manufacturing, medical technology, etc., which have many PhD or postdoctoral applications, current Fintech applicants still have a lot of industry experience to apply, which shows that talents in this industry are still very scarce, whether it is Domestic or foreign.

❿ Is it difficult to develop a blockchain public chain? How many domestic companies can do it

Blockchain is a distributed data storage, point-to-point transmission, consensus mechanism, New application models of computer technology such as encryption algorithms. Blockchain is an important concept of Bitcoin, it is essentially a decentralized database, and as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains information on a batch of Bitcoin network transactions. , used to verify the validity of its information (anti-counterfeiting) and generate the next block.

The biggest problem if such technology is to be put into application is the "impossible triangle problem"

That is, it cannot achieve scalability (Scalability) and decentralization (Decentralization) at the same time. ), security (Security), you can only get two of the three.

Most of the public chain projects currently on the market are difficult to put into use on a large scale.
