『二』 2018-10-02 Xiaobai learns blockchain - what is the main chain
1. What is the main chain
The main chain can be understood as a formally launched and independent blockchain network. It is a trusted blockchain network recognized by the blockchain community, and its transaction information is recognized by all members. Valid blocks will be appended to the blockchain on the main network's block ledger after consensus on the blockchain network.
2. Characteristics of the main chain
1. Compared with the test network, the main chain is an officially launched effective blockchain and an independent blockchain network. .
2. The first blockchain originally created can be called the main chain, and the blockchain of contracts and agreements can be deployed on the chain.
3. Application of main chain
The most successful application of main chain is Ethereum. Most crowdfunding projects on the market are developed based on Ethereum. Yes, its tokens are all tokens issued on Ethereum. It can be understood as: Ethereum is a computer operating system, similar to the Windows system, and the various tokens on Ethereum are equivalent to those on our computers. With various software, developers can pay Ethereum to run projects on Ethereum.
『三』Blockchain Graduation Project Proposal
Background of the project research:
With the development of modern technology and information industry, at this stage, The fourth industrial revolution is beginning to take shape, and the world is about to enter a technological era centered on new technologies such as the Internet and artificial intelligence. At the same time, blockchain technology has emerged as the times require and has become a hot topic of concern for many international governments and industries. blockChain technology has been regarded as the core technology with the greatest potential to trigger the fifth round of disruptive revolution after steam engines, electricity, information and Internet technology. In the past 10 years, with the strong support of the government and policies, the development situation of my country's philanthropy has been relatively optimistic. However, as the scale of charity continues to develop and expand, my country's public welfare undertakings have gradually revealed some shortcomings. The biggest problems existing in traditional public welfare undertakings are insufficient credibility, imperfect internal management of charitable organizations, and high costs. However, many Internet public welfare service companies are currently actively using the new technology of blockchain to solve this problem. Blockchain technology has the characteristics of decentralization, information traceability and non-tampering, openness and transparency, and smart contracts. It can make up for the shortcomings of traditional public welfare undertakings such as opaque information and low management efficiency. Blockchain technology will enter public welfare undertakings and will Bring new development opportunities to the charity industry.
The main content of the research: This topic mainly includes the following three aspects:

[if !supportLists] 2. [endif] Make a public welfare query webpage based on blockchain technology
[if !supportLists] 3. [endif] The query system Application issues and explanations
Purpose of the research:
As the scale of my country’s public welfare continues to develop and expand, our shortcomings have also been exposed, including lack of credibility, and charitable organizations There is a lack of management, and the use of blockchain technology can solve this problem. This technology will track and store data and behaviors throughout the donation process, realize the complete disclosure of the public welfare chain, enable donors to effectively supervise, avoid shortcomings such as low efficiency and clear fund flows, control risks for public welfare projects, and improve Credibility and transparency of public welfare projects promote the development and progress of public welfare projects and enhance trust between people. According to the attributes and characteristics of the blockchain system, public welfare enterprises can implement full-cycle tracking, evidence storage and auditing of data and behaviors in the public welfare process, so that all parties involved in public welfare projects can conduct full-process tracking and effective supervision of the project, avoiding Due to the shortcomings of artificially reducing efficiency in public welfare, it provides a rational method for public welfare projects to control risks and judge effects, improve the transparency of public welfare undertakings, and promote the development of public welfare.
Significance of the project research: This project intends to develop an open and transparent system for tracking public welfare donations based on blockchain technology and combined with the actual development of public welfare undertakings in my country. Through in-depth analysis of blockchain technology and charity business, we found that blockchain technology has natural advantages in solving the problem of public welfare transparency. Blockchain technology can be understood as a distributed accounting method that can recordAll transaction information is guaranteed not to be tampered with, which determines that wherever justice, fairness, and integrity are required, blockchain has a lot of room for technology. At the same time, the addition of smart contracts directly solves the business problem of earmarked funds.
Eventually, trust between citizens will be enhanced, donation channels will be accelerated, and the development of social donations will be promoted
2. Literature review (current status and development of relevant research at home and abroad Trend)
