Knowledge that blockchain must know

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!

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

3. Both became families

4. There is a lot of knowledge about blockchain, such as blockchain, digital currency and blockchain technology. I suggest you go to 900 million finance and economics to have a look. They have all kinds of Xiao knowledge

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. There is a big difference between foreign and domestic mining machine settings. It is suggested that mining machine settings should be in foreign countries, but not in China.

7. Little knowledge of blockchain: what are the characteristics of blockchain
nowadays, blockchain has become an area of public concern, and many enterprises have already studied the implementation of this technology. However, there are still a large number of people who are not familiar with the relevant concepts of blockchain technology. Recently, Viking Research Institute and think tank a jointly proced the blockchain instry dictionary. Bianews, as a media partner, has been authorized to popularize the knowledge of blockchain every day
today, bianews will bring you a little knowledge of blockchain. (2) the characteristics of blockchain
1. Anonymity / anonymousness because the data exchange between the nodes of the blockchain follows a fixed and predictable algorithm, the blockchain network does not need to be trusted and can exchange data based on address rather than personal identity
2. Autonomous / autonomous blockchain adopts consensus based mechanism, which enables all nodes in the whole system to exchange data, record data and update data freely and safely in a de trusted environment, without any human intervention
3. The open / openness blockchain system is open, and any node can have the total account book of the whole network. Except that the private information of the parties directly related to the data is encrypted by asymmetric encryption technology, the data of the blockchain is open to all nodes, so the information of the whole system is highly transparent
4. The digital nature of programmable / programmable distributed ledger means that blockchain transactions can be associated with computing logic and are programmable in nature. Therefore, users can set algorithms and rules to automatically trigger transactions between nodes
5. The traceability / Traceability blockchain stores all the historical data after the genesis block through the block data structure, and any data on the blockchain can be traced back to its origin through the chain structure
6. Tamper proof / after the information of tamper proof blockchain is added to the blockchain through consensus, it is jointly recorded by all nodes, and the mutual correlation is ensured through cryptography, so the difficulty and cost of tampering is very high
7. The collective maintenance / collectively maintain blockchain system is jointly maintained by all the nodes with maintenance function. All nodes can query blockchain data and develop related applications through open interfaces
8. No license / permissionless no license means that all nodes can request to add any transaction to the blockchain, but only if all users think it is legal.

8. 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.

9. 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.
