Can liberal arts students learn block chain

1. 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.

2. Blockchain technology is a very complex technology. Of course, it's not very easy to learn. Because if very good, empty words will not be so gold. But people with low ecation can also learn, because this kind of learning also depends on talent
blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects
characteristics of blockchain technology
decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
security. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously

3. Digital line graphic (DLG) is the vector data set of the existing topographic map elements, which stores the spatial relationship and related attribute information among the elements, and describes the surface targets comprehensively. Digital line map can be enlarged, roamed, inquired, checked, measured and superimposed. Its data is small, easy to layer, can quickly generate thematic map, so it is also called vector thematic information

in the early stage of digital surveying and mapping procts proction, the proction of digital raster map is generally made by using scanner to scan the analog procts of topographic map to obtain digital raster image, which is made by deformation correction, coordinate orientation and image processing. With the popularity of digital procts today, especially with the widespread use of digital line drawing in the form of vector, various views on the application prospect of digital raster map can be described as "different people have different opinions". As a matter of fact, e to its high-tech character and large investment, especially the abundance of information, digital line drawing procts have a high price, which makes some users who use drawings and as the background of some information procts flinch,

4. Blockchain technology uses cryptography to generate a series of data blocks. Each data block contains all the network transaction information in the past, which is used to verify the authenticity of the information and generate the next data block
Xinlian app is a data mining and content publishing platform perpendicular to the blockchain instry, providing users with valuable news information of the blockchain instry and authoritative real-time market interpretation
American blockchain expert Melanie Swan divides the application of blockchain technology into three stages: in stage 1.0, blockchain technology is mainly used in the programmable currency represented by bitcoin; In stage 2.0, programmable finance based on blockchain technology appeared; Blockchain technology will be extended to legal, Internet of things, medical and communication fields in 3.0.

5. There is a future, but some projects are hyped up. Two days ago, Zhu Jiawei, the COO of fire coin group, gave a speech at Lakeside University. You can refer to it“ Blockchain is an ongoing proctivity revolution. We should seize the opportunity of the times. But we should also have a clear and scientific understanding of the principle and role of blockchain. If we overestimate the role and prospects of the block chain, excessive speculation and blindly follow suit will inevitably lead to bubbles. "

6. What's the matter? What's the matter?????

7. No foundation, want to learn graates can learn, in addition, there is a certain technology, want to learn can also learn. Study must be focused and persistent. Ask more teachers, practice more, in fact, can learn. Heima programmer opens classes in Beijing Campus

8. Blockchain 2.0 is to write human's unified language, economic behavior, social system and even life as a basic software protocol. Unified language unifies the natural languages of different nationalities into a low entropy expression form and provides its interface with computer language; Human economic behavior, social system and life regeneration mechanism are collectively referred to as time monetary system. Blockchain 2.0 is a distributed artificial intelligence operating system integrating unified language and time currency<
