Blockchain needs knowledge

1. If you are interested in blockchain technology, you can learn the knowledge of cryptography at the beginning, and learn how to strengthen contracts other than trust through numbers. This is the most basic principle of blockchain. Then you can look at the programming books, understand the basic code, and do simple programming. After that, you can download some common blockchains, Study its code arrangement, see how it adds contracts, and make simple modifications to build its own smart contracts. Of course, if you are only affected by the recent price and hype and decide to join the instry, I suggest you learn more about the Bulls who hype it, listen to their opinions, and learn how others reap!

2. According to the current talent demand in the blockchain field, it can be roughly divided into the following categories:
1. Build a distributed ledger application based on DLT technology to realize the business requirements of customers on DLT. At present, the more famous one in this field is REBO. So what does DLT mean? Just look at what REBO is doing
2. Develop your own application on the existing public chain. At present, most companies are doing this. This category is also characterized by low threshold, high business potential and low risk
3. Companies develop their own public chains, which have the greatest potential in the future, but also have the highest risks and technical difficulties
4. Blockchain ecological infrastructure. For example, mobile wallet, hardware cold wallet, trading platform, blockchain content platform and so on are the blockchain instries with the highest commercial profits at present. Relatively speaking, the threshold is low and the risk is low, but there are many competitors
if we start from technology, what languages and knowledge do we need to learn
for the first class, go language is necessary, because DLT is mainly based on go language, and it also needs to master certain application development ability, because it must be a piece of software rather than a bunch of command-line source programs delivered to customers. For the second category, the mainstream of smart contract is the solidness language of Ethereum smart contract, so if you want to enter the second category of enterprises, you need to start with Ethereum. The third type of public chain development, the mainstream is C + + and go, but there are also many famous projects are implemented in trust, such as: Facebook's Libra, fire coin's nervos and so on. In fact, the fourth category has little to do with blockchain technology, because development such as trading platform does not need blockchain technology
in addition to the above technical hard power, blockchain companies prefer "slash youth", that is, talents who master multi field knowledge at the same time, which can be divided into three categories: finance and blockchain, content operation and blockchain, community operation and blockchain. Among them, the third kind of talents is the rarest, because most technical talents are not good at communication and exchange. However, e to its distributed characteristics, blockchain especially needs the joint efforts of the community to create and maintain a chain
in the end, many people mistakenly think that blockchain is a brand new instry, and that blockchain is totally different from traditional fields. This is actually a big mistake. From what has been written above, you can also find that in the end, blockchain still needs to solve the actual needs in reality. The only difference is that the tools to solve the needs have changed, so don't think that only knowing blockchain can kill all sides, It is very important to have the basic knowledge of the requirement field
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

1. Application of blockchain technology in the banking instry the biggest feature of blockchain technology is decentralization, which will rece a lot of costs for the banking instry. The development of digital currency will make it possible for banks to realize real-time digital transactions. For example, in bill transaction, bank bill transaction always relies on the third party to realize the transfer of valuable documents. Even in electronic bill transaction,

also needs to be authenticated through the information of central bank ECDs system. The blockchain technology can realize the point-to-point value transmission, which no longer needs centralized system control. This not only speeds up the bill transmission speed, but also reces the mistakes caused by human factors. The rection of process will naturally rece the demand of the bank for personnel and save the labor cost of the bank

2, the application of blockchain technology in the insurance instry

blockchain technology also has incomparable advantages in the insurance instry. From the perspective of data management, the application of blockchain technology can effectively improve the risk management and control ability of insurance companies, including the risk supervision of insurance companies and the risk management of policyholders

the application of blockchain technology in the insurance instry can strengthen the internal risk supervision of insurance companies. Blockchain technology can record the daily operation process of insurance company on the node, realize the in-process control of the company's capital flow, investment situation, compensation amount and other business, and improve the company's risk management and control ability

3. Application of blockchain technology in the securities instry

4, blockchain technology and financial infrastructure

blockchain technology is a decentralized mechanism for value exchange, which will lead to earth shaking changes in the existing financial infrastructure characterized by centralization

5. Application of blockchain technology in supply chain, It has become an effective guarantee for enterprise bank's loan credit, financing credit and transaction credit

4. Both became families

5. The key to the implementation of blockchain technology in the real economy should be based on the pain points of an instry, with foundation and application scenarios, rather than creating a new application scenario for human. In fact, issuing indivial currency and upgrading the main chain can not be called landing. The real landing should be integrated with the real economy, creating value-added, breaking away from the virtual to the real, serving the real economy, and improving the efficiency of all kinds of social activities
then, how to judge whether blockchain technology is reliable depends on two main points
first, there should be a real application scenario. No matter how small the application scenario is, it must be valuable
whether blockchain technology can finally be implemented depends on many complex factors, and one of the key points is the application scenario. To find the corresponding application scenario, we should start from the technical characteristics of blockchain itself. Blockchain technology can provide decentralized, tamper proof, safe and reliable characteristic guarantee without introcing third-party intermediaries
Second, the application of blockchain technology should be able to solve problems, not manufacturing problems
with real application scenarios, it also hit the pain points in the instry, but these are not enough to make blockchain technology truly land in the real economy and realize the integration with the real economy. Because the most critical point depends on whether the blockchain technology is applied to solve the problem
with the application of blockchain technology and the assistance of some Internet of things devices, investors can query the real-time and dynamic data of the project at any time, and can directly monitor the progress of the project in different places even without leaving home
using blockchain technology to solve the original difficult problems, combined with the real application scenarios, the implementation of blockchain technology in the real economy has become a natural thing.

6. Blockchain technology involves a wide range of disciplines and contents, including network communication, data storage, data encryption, consensus mechanism, security mechanism, cryptography and other related contents. Only by comprehensively mastering these knowledge can we better master the blockchain technology. In addition, the most important thing for learning blockchain technology is to use blockchain in practice, and the real purpose of learning technology is to develop applications that are helpful to life and proction. Xuanling technology has been committed to the development of blockchain technology related applications, and has an experienced development team. If you have relevant intention, you can contact the official website.

7. There are many basic definitions of blockchain. Here, I will analyze the opinions of different schools, and use a more understandable explanation:
blockchain English Name: blockchain, also known as block chain, is a kind of chain data structure that combines data blocks in chronological order, It is a distributed account book that can not be tampered with and forged by means of cryptography
blockchain is essentially a distributed database, which is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block
2. Working principle
the core potential of blockchain lies in the characteristics of distributed database and how to help transparency, security and efficiency
in the past, institutions used a central database to support transaction processes and calculations. The control of the database is in the hands of its owner, who manages the access and update rights to the database, which limits the transparency and scalability, and makes it difficult for outsiders to ensure that the data records are not manipulated
at the same time, e to technical limitations, distributed database is basically impossible to achieve. But with the development of software, communication and encryption technology, it is possible to build a distributed database across organizations. Blockchain has graally emerged
3. Core idea
the basic idea of blockchain is to establish a network-based public ledger (data block), each block contains the information of a network transaction. All the participating users in the network work together to keep accounts and check accounts. All the data are open and transparent, and can be used to verify the effectiveness of the information. In this way, the authenticity and non tamperability of information can be guaranteed at the technical level without the central server as the trust intermediary.

Nowadays, in order to face the pressure of life, people are doing some network part-time jobs. For example, blockchain is a good network part-time job, and it is also relatively easy. Especially for college students, it is a very suitable network part-time job< so for those who don't understand blockchain, what aspects should they learn from? This can be developed according to its own situation. If you have the conditions, you can buy some information on the Internet to view the relevant content. You can also search for some relevant knowledge on the Internet to learn. Of course, you can also consult friends who understand it

in addition, the most important point is to understand the background knowledge and historical structure of blockchain, what is blockchain, and really understand its meaning. When successfully contacting the blockchain, don't be proud. Be open-minded to learn how other people do the blockchain, and have a persistent heart. In this way, you can quickly master the blockchain

9. At present, we only need to understand some basic concepts. The most extensive application of blockchain is in the field of financial technology. As a kind of underlying technology, blockchain is the technical implementation of bitcoin, so we only need to understand the principle. The application of blockchain technology needs virtual currency. The exchange is the place where all kinds of virtual currencies are traded, so we should pay more attention to the exchange, which is related to our own life after all. I recommend you to the okex bitcoin exchange, which is the largest exchange in the world.
