Ⅰ What are the prospects of blockchain finance?

1. In fact, the combination of blockchain technology and finance is not accidental. Simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, and traceability. Finance is cooperation based on trust, and these characteristics of blockchain lay the foundation for creating trust. Blockchain technology is of great significance in solving problems in the financial field such as high credit risk, low capital utilization efficiency, and high payment processing costs.
2. In reality, Bitcoin is not equal to blockchain. Digital currency is just one of the applications of blockchain technology in the financial field. In the fields of supply chain finance, payment and clearing, trade finance, financial transactions and other fields, "blockchain +" has rich application scenarios and imagination space.
3. Industry insiders pointed out that although the application prospects of blockchain technology are broad, At present, there are only a small number of projects that have actually been implemented and produced social benefits. Blockchain technology is in the early stage of development and still needs to be viewed rationally. In the next step, blockchain technology should be used to explore digital economic model innovation and add impetus to the optimization of the business environment. , to provide support for promoting high-quality economic development.

Ⅱ Briefly explain what blockchain is

Blockchain is a term in the field of information technology. In essence Technically speaking, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology It has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.

On January 10, 2019, the State Internet Information Office issued "Blockchain Information Service Management" Regulations". On October 24, 2019, during the 18th collective study session of the Political Bureau of the Central Committee, General Secretary Xi Jinping emphasized that "blockchain should be used as an important breakthrough for independent innovation of core technologies" and "accelerate the promotion of blockchain technology and industry "Innovative development". "Blockchain" has entered the public eye and become the focus of society.

On December 2, 2019, the word was selected into the top ten buzzwords of 2019 by "Biting Words".

III 360 discovered what epic vulnerabilities in the blockchain

According to news on May 29, recently, the Vulcan team of 360 Company discovered a vulnerability in the blockchain platform EOS. A series of high-risk security vulnerabilities. It has been verified that some of these vulnerabilities can remotely execute arbitrary code on EOS nodes, that is, they can directly control and take over all nodes running on EOS through remote attacks.

Blockchain network security risks require urgent attention

EOS is a new blockchain platform called "Blockchain 3.0". The currency market value is as high as 69 billion yuan, ranking fifth in the world in market value.

In the blockchain network and digital currency system, there are many attack surfaces in nodes, wallets, mining pools, exchanges, smart contracts, etc. The 360 ​​security team has previously discovered and exposed multiple attacks against Serious security vulnerabilities in digital currency nodes, wallets, mining pools, and smart contracts.

The series of new security vulnerabilities discovered by the 360 ​​Security Team in the smart contract virtual machine of the EOS platform are a series of unprecedented security risks. No security researchers have discovered such problems before. This type of security issue not only affects EOS, but may also affect other types of blockchain platforms and virtual currency applications.

IV Want to know what are the development and applications of blockchain

The application scope of blockchain covers many industries

At present, one of the earliest applications is Bitcoin. The blockchain underlying technology platform based on Bitcoin, as the name suggests, is the Bitcoin network

Other blockchain underlying technologies now include IBM's Febric, Yinlian’s blockchain underlying technology platform, etc.

Up to now, the application of blockchain mainly has the following directions: 1

Financial industry

< p>In the financial industry, blockchain can be said to be the most popular FinTech (financial technology) in the world

There are also endless application cases in the financial industry, such as: Sunshine Insurance was launched on July 29, 2016 "Blockchain Aviation Accident Insurance Card"

Most aviation accident insurance will only issue insurance claims when an aircraft accident occurs. In most cases, fake insurance policies bought by customers are not easy to detect. Based on the blockchain chain technology,The entire process of the card form from the source to the customer can be traced. All parties can not only check the authenticity of the card form, but also facilitate subsequent processes, such as claims settlement.

At the same time, without a middleman, the unit price of the insurance card will remain unchanged. Significantly reduced

The economic benefit: this product costs 60 yuan to purchase one copy, can be used by 20 people, and can obtain aviation accident insurance of up to 2 million yuan each time, which is equivalent to 3 yuan per time. You can get a guarantee of 2 million yuan from Zaonai

To a great extent, it saves consumers’ expenditures and insurance companies’ costs

Also, Yinlian Technology in September 2016 Released commercial bank collateral, etc., this product is mainly used for the registration of real estate, vehicles and other assets to prevent repeated mortgages, and applies the consensus mechanism of the blockchain to improve inter-bank work efficiency

Financial Bank

IV What is the concept of blockchain

Blockchain is a digital ledger that can be jointly recorded. It will record all transactions that have occurred and been unanimously approved by the system. It's equivalent to the whole family mobilization method of accounting. You are accounting, and your father and mother are also accounting. They can all see the general ledger, but the information that has been saved cannot be tampered with.

The concept of blockchain was first proposed by Satoshi Nakamoto in 2008. Blockchain then became a core component of the electronic currency Bitcoin, serving as the public ledger for all transactions. By leveraging peer-to-peer networks and distributed timestamp servers, blockchain databases can be managed autonomously.

(5)29 Extended reading on blockchain:

Types of blockchain

1. Public blockchain

Any individual or group in the world can send transactions, and the transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. The public blockchain is the earliest blockchain and the most widely used blockchain. The virtual digital currencies of all major bitcoins series are based on the public blockchain. There is only one blockchain corresponding to this currency in the world. .

2. Consortium (Industry) Blockchains

Industry Blockchains (Consortium Block Chains): Multiple pre-selected nodes are designated within a certain group as bookkeepers. The generation of a block is jointly decided by all pre-selected nodes (pre-selected nodes participate in the consensus process). Other access nodes can participate in transactions, but do not participate in the accounting process (it is essentially still managed accounting, but becomes distributed accounting, pre-selected The number of nodes and how to determine the bookkeeper of each block has become the main risk point of the blockchain). Anyone else can make limited queries through the open API of the blockchain.

3. Private blockchain

Only use the general ledger technology of the blockchain for accounting. It can be a company or an individual who has exclusive access to the writing of the blockchain. With access permissions, this chain is not much different from other distributed storage solutions.

VI Ningxia: Promote blockchain and other technologies to achieve digitalizationTransformation

Currently, Ningxia is promoting the application of digital technology in industry, education, medical and other fields. Combined with the construction of smart parks and the digital transformation of the ten major industrial industries, 60 intelligent transformation projects were organized and implemented to drive the development of digital industrialization through industrial digitization. We will implement 29 smart application scenario projects around education, medical care, cultural tourism, water conservancy, transportation and other fields, carry out big data pilot demonstrations, and provide demonstration cases for the integrated application of information technology. Promote the Internet of Things and blockchain technology, promote the effective integration and utilization of online and offline resources, and achieve digital transformation.


The International Monetary Fund plans to "strengthen" digital currency monitoring

According to an article published by the International Monetary Fund (IMF) on Thursday paper, the organization plans to “increase” monitoring of digital currencies. The article stated that the IMF must increase resources to seek to "monitor, advise and help manage this far-reaching and complex digital currency transformation." The article stated that rapid technological innovation is ushering in a new era of public and private digital currencies. Payments will become easier, faster, cheaper, more accessible and will rapidly cross borders. These improvements can promote efficiency and inclusivity, bringing significant benefits to all. However, such implementation will only happen if the IMF can “keep pace with policy challenges,” which requires a deeper look at the prospects for the digital economy. The IMF plans to work with institutions “consistent with its mandate” such as central banks, regulators and the World Bank, while expanding its own digital currency research. The IMF will also look at CBDC, stablecoins, crypto-assets, etc., and will study how these assets represent financial independence, how they can serve as reserve currencies, and how they can replace the current payment system.

From a financial perspective, blockchain and digital currency are actually a new generation of digital financial system. The digital financial system is built on the financial infrastructure of blockchain digital currency.

From a business perspective, blockchain technology has its own characteristics, that is, it is sufficiently digital, it is cross-border, cross-time and space, and cross-organization. The flow of data has no boundaries, so the blockchain is distributed at the same time, it is self-organized and decentralized.


Therefore, the origin of blockchain and the application of any new disruptive technology have always had two routes, or two methods. One way is to regard it as a tool and use it to improve the traditional business model and obtain an improvement in marginal benefits. The other is to treat it as a system to reconstruct the underlying logic of business.
