『一』How to apply blockchain

1. Jinxunque logistics field:

Blockchain in international exchange and letter of credit , equity registration and stock exchanges and other financial fields have potentially huge application value. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.

2. Internet of Things and logistics fields:

Blockchain can also be naturally combined in the fields of Internet of Things and logistics. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered a promising application direction of blockchain.

3. Public service field:

Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields, but the centralized characteristics of these fields are also It has brought about some problems that can be transformed using blockchain. The decentralized, fully distributed DNS service provided by the blockchain can realize domain name query and resolution through point-to-point data transmission services between various nodes in the network, and can be used to ensure that the operating system and firmware of an important infrastructure are not Tampered, you can monitor the status and integrity of the software, detect bad tampering, and ensure that the data transmitted by systems using IoT technology has not been tampered with.

4. Digital copyright field:

Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the ownership of works. Authenticity and uniqueness. After the rights of the work are confirmed on the blockchain, subsequent transactions will be recorded in real time, realizing full life cycle management of digital copyright, and can also be used as a technical guarantee in judicial evidence collection. For example, MineLabs, a startup company in New York, USA, has developed a blockchain-based metadata protocol. This system called Mediachain uses the IPFS file system to realize copyright protection of digital works, mainly for copyright protection applications of digital pictures.

5. Insurance field:

In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the insurance policy can automatically settle claims. A typical application case is LenderBot, which was launched in 2016 by the blockchain company Stratumn, Deloitte and the payment service provider Lemonway. It allows people to register for customized micro-insurance products through the chat function of Facebook Messenger, which is exchanged between individuals. High-value items are insured, and blockchain represents them in loan contracts.replaced a third-party role.

6. Public welfare field:

The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain, and can be transparently and publicly disclosed conditionally to facilitate social supervision.

『二』How to build a blockchain website

Websites are no longer mysterious and no longer a high-tech job. Ordinary users can also easily build relatively professional websites. Let me briefly introduce to you some procedures and precautions for building a personal website.
1. Domain Name
If you want people to visit your website, a domain name is essential. The domain name should be as short as possible and as easy to remember as possible, such as the .top domain name. Of course, there are not many domain names that are easy to remember and have characteristics. You need to consider this yourself, as long as you feel that there is a certain pattern or it is easy for users to remember. That’s it.
2. Space
To build a website, you must have a space, which is a place to store the website. For individual users, it is recommended to purchase a virtual host. When purchasing a web host, look at its service, speed, response time, etc. Generally, you can choose a service provider with a certain reputation.
Note: Domain name and space are currently good choices for domestic service providers such as Alibaba Cloud, Western Digital, and China Data.
3. Website program
Of course, the website program should be ready-made, because there is no need for individuals to compile a website program from scratch, and they do not have the ability. Nowadays, there are ready-made website management systems on the Internet. There are many such systems. You can choose based on your own comprehensive trial.
When choosing a website program, its versatility and secondary development must also be taken into consideration. For those that are not very versatile and are not conducive to the second phase of development, although they are powerful, they are not recommended because it will be very troublesome when the website needs to be designed with personalized functions after it reaches a certain scale. In addition, try to choose asp (asp.net) for programs. PHP, JSP, etc. are not particularly popular in China. Try to choose asp.net between asp and asp.net. After all, it is based on the .net architecture and is the development trend.
4. Website Design
After selecting the website program, you need to design the website according to your own needs. Generally speaking, it is best if there are professional artists and programmers to make modifications. However, individual webmasters may not necessarily have this condition and can choose intelligent website building from service providers.

『三』How to build blockchain services

Blockchain services refer to developing public chain applications based on the infrastructure provided by the public chain and running the applications to provide services. For example, smart contracts are used to develop public chain applications on Ethereum and run on Ethereum nodes to provide effective services to the public. On Bitcoin, take advantage of Bitcoin’s limited functionality and provide someCertificate deposit service.
Blockchain developers should establish effective channels that can collect the shortcomings of the current blockchain and make targeted improvements. This process is called Improvement Proposals: Bitcoin Segregated Witness ( Consisting of a series of BIPs) is a good example. Developers at the application layer can use the IP process to feed back problems discovered during use to developers, forming a virtuous cycle. And the IP process should not be limited to the technical field, but should go deep into the Business Layer.
The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the only approved "Blockchain Technology Professional" pilot of the "Smart Learning Workshop 2020- Xueshuo Innovation Workstation" launched by the School Planning, Construction and Development Center of the Ministry of Education of China. workstation. The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

Hello, thank you for the invitation!

How can enterprises build their own blockchain?

With the popularity of various currency transactions, the development of the exchange industry has been driven. So as a novice who wants to cross industries, how to establish a blockchain exchange development company? Chainsoft Network summarizes the following points for you.

Please click to enter the picture description

1. Determine the operating scope of the exchange development company

Determine the company's The scope of operations is very important, as it determines whether the company has the potential to be profitable. Relevant laws and regulations vary from region to region every day, so the first step is to understand the local laws and regulations, and obtain the necessary licenses and approvals to open a Bitcoin exchange according to your scope of operations, so as to avoid violating local laws and regulations, and bring To cause unnecessary trouble.

2. Check the country’s regulations and compliance requirements

Almost all governments require entities involved in currency exchange businesses to comply with Know Your Customer (KYC) norms. KYC is the process by which businesses verify the identities of their customers through government-issued ID cards or passports. The main purpose here is to prevent money laundering. Make sure to comply with your country’s KYC norms and integrate suitable customer verification procedures in your exchange.

3. Work with a bank or payment processor

You need to work with a bank or payment provider to process payments via fiat currency. You can choose a trustworthy bank with extensive online facilities.

4. Create liquidity on your exchange

Any exchange needs liquidity to operate successfully. Customers are hesitant to place an order or even deposit funds unless they see complete order and trading activity. New trading naturally encounters liquidity issues.

5. Ensure high-level security of transactions and customer data

AnyExchange development companies all require top-notch security to ensure that exchange operators and traders’ funds remain safe. This should also apply to your customers’ private data, including their KYC details and bank account information. The Gox breach, a security flaw that went unnoticed for years, resulted in the theft of nearly 1% of all Bitcoins in circulation at the time. According to Chainsoft Network, one-third of all Bitcoin exchanges were hacked between 2009 and 2019. Therefore security must be your top priority in trading.

6. Establish customer support channels

Finally, customer support is another important component of a successful exchange. Staff are needed to approve KYC requests, answer customer complaints, process deposits and withdraw fiat currency, etc. A fast customer support mechanism ensures that your customers start trading from the day they sign up and generate revenue for your exchange.

I hope this helps you solve related problems. For more details, please feel free to consult and discuss!

『Wu』 How to develop blockchain applications based on ethereum

Currently, there are roughly two ways to do blockchain development.

Developed directly based on ready-made blockchain development platforms (mainly Ethereum and HyperLedger). Shanqie

Build a blockchain from the ground up. On the surface, there is no doubt that it should take the first path in terms of development efficiency, investment costs, industrial cooperation, etc., but in fact the situation is different. Much more complex.

The development of blockchain still requires the actual participation of more code writers in order to be truly promoted.

Now the entire technology community’s attention is mainly focused on Web and mobile development, and the supply and sale of related talents are booming. However, some interested people have begun to turn to promising technologies such as big data analysis, deep learning, and VR/AI.

(6) How to build a blockchain application Extended reading

General Secretary Xi Jinping emphasized at the 18th collective study session of the Political Bureau of the CPC Central Committee, “Take blockchain as a core technology since"an important breakthrough for major innovation" and "accelerate the promotion of blockchain technology and industrial innovation and development."

The forward-looking judgment of the Party Central Committee has brought "blockchain" into the public eye and has become an important part of financial capital, real economy and The common concern of public opinion.

From Internet power to big data, from media integration to blockchain, the Political Bureau of the CPC Central Committee collectively studied and aimed at the forefront of technological change, demonstrating the direction and forward-looking judgment of the Party Central Committee and future foresight, leading the pace of China's industrial reform and economic transformation. This collective study by the Political Bureau of the Central Committee specifically emphasized "blockchain", which opened up imagination space for the development and application of blockchain.

From a technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming. From an application perspective, simply speaking, blockchain is a distributed shared ledger and database , which has the characteristics of decentralization, non-tampering, full traces, traceability, collective maintenance, openness and transparency.

These characteristics ensure the "honesty" and "transparency" of the blockchain and provide a good foundation for the blockchain. Chains lay the foundation for creating trust. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

『 7』 How to apply blockchain

For blockchain and traditional IT and data technologies, I think the future development of blockchain technology must be "integration".

1) Traditional financial IT companies:

Blockchain technology can be quickly applied in the financial IT and insurance IT fields due to its outstanding technical characteristics of openness, transparency, uniqueness, safety and reliability.< /p>

2) Traditional IT sharing companies:

The core capabilities of blockchain are mutual trust and sharing, so it is easy to be fully integrated with the concept of the sharing economy and then applied.

p>

3) Traditional IT technology companies:

Blockchain will become part of the computer cloud services and big data of traditional IT companies. Now multinational IT companies are making great efforts in security and analysis , and all these services can be built on the basis of blockchain.

4) In addition, blockchain also has great complementary advantages in the field of AI companies. Blockchain is a new spring. Modify distributed database technology, so blockchain technology can solve the problem of data credibility in AI applications. With blockchain technology, AI can focus more on algorithms.

But I feel that blockchain Chain technology is still in its infancy and needs time to be researched and verified. The final chance of annihilation is always reserved for those who are prepared!
