A. Why is Fujian the first to issue digital diplomas in blockchain technology?

Combined by Sunshine College, Taiwan Kaohsiung University of Science and Technology and Taiwan Sunshine Blockchain Technology Co., Ltd. The digital graduation certificate system jointly developed by the R&D team and based on blockchain technology has been officially launched recently. In addition to traditional paper graduation certificates and bachelor's degree certificates, the 2017 Sunshine College undergraduate graduates can also obtain their graduation certificates through a specially developed application based on blockchain technology, becoming the first batch of digital graduation certificates from colleges and universities across the country. of college students.

In order to prevent academic fraud, MIT launched relevant research in 2015 and released the first digital certificate in 2016. The results attracted widespread international attention. London Universities such as the University of Melbourne, the University of Melbourne, and the Russian Financial University have also successively carried out research and applications in this field. This system was jointly developed by Sunshine College, Taiwan Kaohsiung University of Science and Technology and Taiwan Sunshine Blockchain Technology Co., Ltd. for nearly two years. After a period of testing, the system is stable and reliable, and is generally at the leading level in the country. In the future, the system can be easily promoted and applied to other fields such as finance, management, and medical care.

B. Geer software and digital authentication under the blockchain

I first appeared on the Snowball website (https:// xueqiu.com/edit/97626212)

This article is a summary of some simple homework, which involves $Gel Software (SH603232)$ and $Digital Certification (SZ300579)$.

(1) PKI is currently a mature basic framework for information security. It is very mature and very good. There is currently no relevant technology that could replace it. I have been using it and I sincerely welcome it. Paizhuan, willing to communicate. "my country's information security industry is currently in, and will be in, the planning information security stage for a long time (a concept I personally proposed, for reference only)." The characteristic of this period is that the country's military and government affairs fields will continue to vigorously promote and adopt this technology. The civilian field is still in a barren land, and it is precisely this situation that the profit point of 360 has never been the end product, that is the publicity point.

(2) Blockchain and PKI framework are not equivalent concepts. Blockchain can be applied to the basic PKI framework. Blockchain can never replace PKI. I hope everyone will not see certification being lumped together. If PKI disappears one day, it will definitely not be because of the blockchain.

(3) Blockchain and CA are largely issues of the same level. Mechanically, one is decentralization and the other is centralization. The working mechanisms are exclusive, but they do not necessarily cannot be combined. No matter how it is used, the effect on CA will be reduced.

(4) Geer Software Company corresponds to PKI and its applications, while Digital Certification Company focuses on CA and its applications. Of course, the two companies just meet each other, and then talk about business with each other and then... that's all, "and its applications" "The four words are very different.

(5) In addition, it should be noted that if the pure CA business is very regional, it is available in every province, such as Shenzhen CA. Therefore, this is also one of the reasons why I don’t quite recognize the growth of Beijing CA (Digital Certification).

(6) The CA-based PKI solution is currently generally recognized as the best cryptographic technology integrated solution. In the future, it may be a **-based PKI solution. If that day comes, it will be While your software does not need major changes, digital certificates require huge pains and changes.

(7) If Geer launches blockchain research, it will be very beneficial to the development of the national information security commercial encryption field. Of course, it will also be unparalleledly beneficial to the company. But don’t rush into promotion, conduct research and test products.

(8) Although Geer’s current monopoly advantage in the PKI market is good, if blockchain is incorporated into the system, it is likely to become a national-level monopoly advantage, comparable to the rare earth industry back then. , I used to think that only resource stocks deserved to have this level of monopoly advantage.

(9) The market is currently a bit confused about Geer’s valuation, with very low attention and very few understanding of the business. I am willing to wait for 5 years and believe in the profit growth capabilities it can unleash. , of course, the premise is to always pay attention to the development of technology and regular quarterly financial reports for a comprehensive physical examination.

I would like to share some lessons and hope that everyone can give me some advice and give me some advice. Brainstorming is the way to go.

C. What technology is blockchain and what impact does it have on our lives and society?

What is blockchain technology?

Before discussing how to apply blockchain in daily life, let us first talk about what blockchain is and how does it work?

Blockchain is an open distributed database, essentially a computer file used to store information (data).

Blockchain gets its name from its structural features: files are made up of blocks of data, each block is linked to the previous block, forming a chain, and each block contains data such as transaction records and A record of when the block was edited or created, the information (data) is timestamped, which is where the blockchain comes from.

Crucially, unlike centralized databases owned by companies or government agencies, blockchain is not controlled by any one person or entity and the data is fully replicated (distributed) across multiple computers .

Because it is a decentralized way of storing and accessing data, this makes it incredibly secure. Because with a centralized databaseDifferently, attackers do not have a single entry point, and data security is more guaranteed.

In addition to the two major features of decentralization and security, the features that make blockchain a leading technology that distinguishes it from other technologies are:

Immutability: Once on the blockchain, no information can be changed, not even administrators can modify this information. It gives blockchain the advantage of being easily auditable.

Accessible: Information can be easily accessed by all nodes in the network.

No third parties: Blockchain facilitates peer-to-peer transactions, so whether you are trading or exchanging funds, there is no need for approval from a third party. Blockchain itself is a platform.

The impact of blockchain technology?

1. The open and non-tamperable attributes of blockchain technology provide the possibility for a decentralized trust mechanism and have the potential to change the financial infrastructure. Various financial assets, such as equity, bonds, Bills, warehouse receipts, fund shares, etc. can be integrated into the blockchain ledger and become digital assets on the chain, which can be stored, transferred, and traded on the blockchain. It has broad application prospects in the financial field. For example, it has typical applications in cross-border payments, insurance claims, securities transactions, bills, etc.

2. The current IoT ecosystem relies on a centralized network management architecture, and all devices are connected through cloud servers. As the scale of the network expands, the infrastructure and maintenance costs of centralized cloud servers, large servers and network equipment will incur high costs.

In the decentralized Internet of Things, blockchain is a framework that promotes transaction processing and collaboration between interacting devices. Each device on the network can serve as an independent, micro-business entity. run.

3. Public services are factors that promote economic growth and social progress. The supply of public services will have an important impact on various subjects and systems, culture, attitudes, behaviors, etc. in the process of political, economic, and social development. Influence. Traditional notarization relies on the government, but limited data dimensions and unestablished historical data information links often prevent governments and schools from obtaining complete and effective information. Blockchain can be used to create digital proofs that cannot be tampered with. New certification mechanisms can be established in the fields of digital copyright, intellectual property, certificates and public welfare to improve the management level of public services.

D. What kind of technology is blockchain technology?

Blockchain is a distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer New application models of technology. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
Blockchain is the underlying technology of Bitcoin, like a database ledger that records all transaction records. This technology has gradually gained popularity among banks and banks because of its safe and convenient features.financial industry concerns.
In April 2018, a group of scholars from Oxford University announced the establishment of the world’s first blockchain university, Woolf University.
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is distributed cryptographically to ensure that it cannot be tampered with or forged. Account book.
Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure the security of data transmission and access. A new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and manipulate data.
