⑴ What are the current development prospects of blockchain technology

Research strength has increased and research results have been significant

As of the end of 2019, my country’s blockchain technology The number of research institutions has reached 97. In addition, domestic universities have deployed blockchain technology research, strengthened the innovation of blockchain technology theoretical knowledge, and improved the blockchain technology research and development capabilities of universities. By the end of 2019, there were 24 universities in my country participating in strengthening blockchain technology research and development. The core technologies are mainly distributed in the aspects of consensus algorithm, cross-chain, underlying architecture and multi-chain.

Judging from the research results, in terms of consensus mechanism, my country’s consensus mechanism is gradually moving from a single algorithm to a hybrid consensus; in terms of cryptographic algorithms, cryptographic algorithms such as secure multi-party computation, homomorphic encryption, and zero-knowledge proof are continuously integrated and applied. ; Research on cross-chain technology and security technology has gradually become a research hotspot.

From the perspective of blockchain hardware, currently, the world’s most important digital currency mining equipment suppliers are all located in China, including Bitmain, Canaan, and Yibang Technology. Three mining equipment companies account for more than 90% of the market share.

From the perspective of industry applications, the financial industry is currently the industry with the most blockchain technology implementation projects and the richest scenarios, such as supply chain finance, asset certificate aromatization, credit reporting and risk control, etc.

China accounted for 60% of the world’s patent applications in 2019

With the tilt of national policies towards blockchain and the implementation of applications in various fields, blockchain-related patents have gradually gained Attention from all parties. Compared with 2018, the number of blockchain-related patent applications from Chinese enterprises has increased significantly in 2019. Among the top 100 global companies on the list, my country accounts for 63%.

The blockchain industry will be further standardized in 2020

In 2020, my country’s blockchain policies will continue to be favorable, standards and regulations will be more perfect, industry scale will continue to grow, and technology will continue to innovate and develop. , the application demonstration effect in key areas is accelerating. At the same time, based on the problems existing in the development of my country's blockchain in 2019, CCID Blockchain Research Institute proposed to speed up top-level design and formulation, establish a sound regulatory system, accelerate core technology innovation and research and development, promote third-party evaluation and certification, strengthen professional talent training, and accelerate promotion Six suggestions for implementation in various fields.

⑵ What to do if the blockchain information is getting larger and larger

Over the past few years, with the vigorous development of Bitcoin, the number of Bitcoin transactions has increased, and the size of a single block has There is a maximum limit of 1MB, so the free space in the block becomes smaller and smaller. As shown in the figure, the median block size doubled in 2015, growing rapidly from 292KB in January to 749KB in December.

Bitcoin block size

The issue of expansion received full attention and discussion in 2015. Around June 2015, many expansion plans were launched one after another, represented by BIP100, BIP101, BIP102, BIP109,BIP248 and several other plans (Table X).

Although various plans have been proposed, they can basically be divided into two categories: the long-term rule-based faction and the short-term shelving faction. The long-term allocation is ideal and rule-based. It is finalized in one go and no more fussing. The typical representative is BIP101/103, which sets a growth rule and no longer adjusts. The short-term group believes that the future is unpredictable and fixed rules are too simple and violent to solve problems. They hope to set up a short-term and multi-year plan to avoid it for the time being and put it on hold until the future. The representative is BIP100. However, due to the complexity of the voting process, it was later simplified to BIP102/ 109 and so on, while BIP248 has been postponed to 2020, and has simply doubled in recent years.

Since June 2015, after more than half a year of extensive and repeated discussions, the long-term rule-based faction has basically been completely defeated. After Pieter Wuille proposed Segregated Witness at the Bitcoin Hong Kong Scaling Conference in December 2015, the scaling issue has even been simplified to only an upgrade to 2MB, but it has been mired in debate about the implementation time.

A seemingly simple expansion technical issue has caused the Bitcoin community to spend more than half a year, hold several global technical conferences, and engage in countless private wars of words, but there is still no clear conclusion. The profound reason behind this is that raising the block limit value cannot truly solve the Bitcoin expansion problem. Scaling issue

In general, based on the understanding of the Bitcoin network, there are two divisions: clearing system and cash system.

Clearing system

The Bitcoin blockchain is a global, distributed, limited-capacity, expensive system. The value content of each transaction is different. When the block capacity is not enough, we should ensure that high-value transactions enter the block. High-value transactions have the willingness and ability to pay high enough network fees to obtain blocks with high enough priority.

As Bitcoin prospers, the number of transactions will become larger and larger. The limited block capacity will prevent low-value transactions (such as sending 1 cent) from entering the block because low-value transactions cannot be included in the block. May pay high network fees. Then the network degenerated into a clearing system, low-value transactions were driven out, and these transactions were replaced by third-party accounting systems.

Before the emergence of the Lightning Network, third-party accounting systems were mainly off-chain wallet providers. Users trust a third-party wallet platform and deposit Bitcoins into it. Transfers between users on the same platform only bring about changes in account balances and do not generate Bitcoin transactions.

Cash system

The cash system means that all transactions should enter the block. When the block capacity is not enough, the block size limit should be increased in time to expand the system. Transaction blocking may occur in the short term, but in the long run all transactions should be able to be added to the block. Everyone enjoys the tremendous convenience and advantages brought by the Bitcoin system.

Industry Overview

1. Definition

In a narrow sense, blockchain is a combination of data blocks that are connected sequentially in chronological order. A chained data structure and a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.

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 data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.

Blockchain is not a single technology, but a combination of new technologies. Each of these technologies performs its own role, solves different problems, and is combined to form a blockchain. As the basic structural unit of the blockchain, the block consists of two parts: the block header and the block body containing transaction data.

2. Industry chain analysis: the downstream industry covers a wide range of areas

The upstream of the blockchain industry chain is mainly the underlying technology and infrastructure. The underlying technology includes core basic components, protocols and algorithms. Represented by Bitcoin, Litecoin, and Ethereum, a network environment such as distributed algorithms, digital keys, data storage, P2P network protocols, and consensus mechanisms based on blockchain technology, transaction rules, and incentives for miners to join network nodes have been built. Mechanism, representative companies include Xiaoyi, Quantum Chain, Wanxiang Blockchain, etc.; the infrastructure is mainly mining machines.

The midstream is the platform layer, which mainly provides developers with applications based on blockchain technology. It provides productized services such as smart contracts, information security, and data services based on the underlying technology to improve development It provides convenience and scalability for developers to develop applications at the platform layer.

Downstream is the vertical industry application layer. It manifests itself as core application components, including smart contracts, programmable assets, incentive mechanisms, member management, etc.

Industry development history: We are in the era of blockchain 3.0

From the perspective of the development history of global blockchain, in 2008, an anonymous person signed by "Satoshi Nakamoto" published The paper "Bitcoin: Peer-to-Peer Network Electronic Cash System" originally expected to launch a peer-to-peer electronic cash that could circulate freely. The issuance of Bitcoin represented the beginning of blockchain technology; later, in 2013, the launch of Ethereum directly Promote the blockchain into the 2.0 era; at the end of 2017, the popularity of stable coins and theMakerDAO went online, pushing the blockchain into the 3.0 era. By June 2019, Facebook released the Libra white paper, which attracted attention and discussion from all walks of life around the world. Regulatory authorities in various countries have successively spoken out, showing that blockchain technology is reshaping the global financial infrastructure. huge potential. After entering 2021, NFT-based identification technology has emerged and is the first to be applied in the art field.

Industry policy background: Promote the all-round development of blockchain

In 2016, the State Council issued the "Thirteenth Five-Year Plan for National Informatization", which listed blockchain as a new technology for the first time The scope and cutting-edge layout indicate that my country has begun to promote the development of blockchain technology and applications. Since then, various localities in the country have successively introduced blockchain-related policies, providing a good environment for the development of blockchain.

In February 2019, the "Blockchain Information Service Management Regulations" issued by the State Internet Information Office were officially implemented, standardizing the filing basis for the development of my country's blockchain industry. The purpose of promulgating the "Regulations" is to clarify the information security management responsibilities of blockchain information service providers, standardize and promote the healthy development of blockchain technology and related services, avoid blockchain information service security risks, and facilitate the provision of blockchain information services. , use, management, etc. to provide effective legal basis. The introduction of this "management regulations" also means that my country's "supervision era" for blockchain information services has officially arrived.

At the end of October 2019, the Political Bureau of the CPC Central Committee held its 18th collective study session on the development status and trends of blockchain technology. Central leaders clearly emphasized the use of blockchain as an important breakthrough for independent innovation of core technologies. , Accelerate the promotion of blockchain technology and industrial innovation and development. This fully demonstrates that blockchain technology has risen to a national level. Chen Chun, a professor at Zhejiang University and an academician of the Chinese Academy of Engineering, who gave a lecture on the collective study of the Political Bureau of the CPC Central Committee, said at the 2019CCF Blockchain Technology Conference hosted by the Computer Society of China on October 12 that the development of the domestic blockchain industry is ushering in " "Spring Breeze", the research hotspots of China's blockchain technology will focus on two aspects: the key technology of the alliance blockchain and the blockchain supervision technology.

⑸ What is the development trend of China’s blockchain in 2021?

Looking forward to 2021, the top-level design of my country’s blockchain will be further improved, application standards for various industries will be gradually established, and the development direction will be from Technology leads the way into market penetration; blockchain integration applications have begun to be implemented in many fields such as finance, supply chain, government affairs, etc., and the industrial scale will show rapid growth. However, many problems currently faced by the development of blockchain in our country still need to be focused on and started to be solved or alleviated in 2021. For example, the independent innovation capabilities of core technologies still need to be further strengthened, security issues and talent gaps need to be improved urgently, and integrated applications The scene still needs to be explored in depth. Therefore, CCID Research Institute proposed to accelerate the construction of the blockchain ecosystem, improve standards and regulations, improve the supervision system, strengthen the independent innovation capabilities of core technologies, promote the coordinated development of blockchain and other new technologies, and vigorously cultivate professional talents to achieve The blockchain industry is developing healthily.

⑹ What is the development trend of blockchain and the future development trend of blockchain

Policy and market dual-layerThere are broad prospects for the development of the blockchain industry
Driven by both policy and market, China’s blockchain-related industries are expected to move from reality to reality
In the context of the rapid development of blockchain, China is adapting to the needs of globalization. Keep up with the international pace and actively promote the research, standardization and industrialization development of domestic blockchain-related fields. Compared with the background of increasingly strict supervision of digital currencies such as Bitcoin, support and encouragement for blockchain technology has reached a global consensus, and domestic blockchain technology will also receive national and local policies in the next few years. support. Driven by the dual layers of policy and market, blockchain-related industries are expected to move from reality to reality, and blockchain technology will accelerate the exploration of possible application scenarios.
Forecast of global blockchain market size
According to the "In-depth Analysis Report on Business Model Innovation and Investment Opportunities in the Blockchain Industry" released by the Qianzhan Industry Research Institute, the global blockchain market size is expected to increase from 2017 to 2017. It will increase from US$411.5 million in 2022 to US$7.6837 billion in 2022, equivalent to a compound annual growth rate of 79.6%. Given the wide range of applications for distributed ledgers and the rising market value of cryptocurrencies, there is a strong need to improve transparency, security, efficiency and streamline processes, as well as blockchain as a service (
BaaS). As a hot topic of development, the blockchain market will expand rapidly. In addition, communication services, international trade, supply chain management, program platforms, payments, smart contracts, digital identity verification, etc. also urgently need blockchain technology and will create a large number of growth opportunities.
Blockchain, as an integrated application of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other technologies, has become a hot topic of research and discussion by international organizations such as the United Nations and the International Monetary Fund as well as many national governments in recent years. The industry has also increased investment. At present, the application of blockchain has extended to many fields such as the Internet of Things, intelligent manufacturing, supply chain management, and digital asset transactions, and will bring new opportunities to the development of new generation information technologies such as cloud computing, big data, and mobile Internet. , has the ability to trigger a new round of technological innovation and industrial change.
By 2022, the payment sector may occupy the largest share of the blockchain market
Relying on blockchain technology, instant payment of assets can be realized, which not only has the characteristics of non-tampering and digital identity verification, but also can provide Financial institutions and banks significantly save settlement costs. In addition, blockchain makes it possible to automate payments, eliminating the need for middlemen, saving labor costs and time for buyers and sellers. Thanks to the many advantages mentioned above, it is expected that the payment sector will be the most important segment in the entire blockchain market.
The fastest growing region will be Asia-Pacific
Blockchain service providers in the Asia-Pacific region are good at designing and developing user-friendly, cost-saving, and fast cryptocurrency platforms, extending blockchain to multiple Industry application tentacles. Both large enterprises and small and medium-sized enterprises are actively seeking venture financing and investing in the research and development of cutting-edge blockchain technology. In addition, Asia PacificThe real estate industry in some countries in the region is expected to rapidly transform from semi-transparent to fully transparent, which will also help enhance the development prospects of blockchain in the Asia-Pacific region.

⑺ What is the relationship between blockchain and big data storage

The relationship between blockchain and big data storage is as follows:
1. Data security: blockchain Let data flow with real confidence
Blockchain, with its trustworthiness, security and non-tamperability, allows more data to be liberated. Let’s use a typical case to illustrate how blockchain promotes the generation of gene sequencing big data. Blockchain sequencing can use private keys to limit access rights, thereby circumventing legal restrictions on individuals' access to genetic data, and utilize distributed computing resources to complete sequencing services at low cost. The security of blockchain makes sequencing an industrialized solution, enabling global-scale sequencing, thus promoting the massive growth of data.
2. Data openness and sharing: Blockchain ensures data privacy
The government holds a large amount of high-density and high-value data, such as medical data, population data, etc. The openness of government data is a general trend and will have an immeasurable impetus to the development of the entire economy and society. However, the main difficulty and challenge in data openness is how to open data while protecting personal privacy. Blockchain-based data desensitization technology can ensure data privacy and provides a solution for data openness under privacy protection. Data desensitization technology mainly uses encryption algorithms such as hashing. For example, the Enigma system based on blockchain technology can calculate data without accessing the original data, which can protect the privacy of data and eliminate information security issues in data sharing. For example, company employees can safely open access to their salary information and jointly calculate the average salary within the group. Each participant is informed of his relative position within the group but not of the compensation of other members.
Data HASH desensitization processing diagram
3. Data storage: Blockchain is an immutable, full-historical, strongly endorsed database storage technology
Blockchain technology, through the network All nodes in the network participate in calculations and verify the authenticity of their information to reach a consensus across the entire network. It can be said that blockchain technology is a specific database technology. So far, our big data is still in a very basic stage. Trusted blockchain data based on the consensus of the entire network is non-tamperable and full of history, which also enables the quality of the data to gain unprecedented strong trust endorsement. It also brings the development of database into a new era.
4. Data analysis: Blockchain ensures data security
Data analysis is the core of realizing data value. When conducting data analysis, how to effectively protect personal privacy and prevent core data leakage has become the primary consideration. For example, with the popularization of fingerprint data analysis applications and genetic data detection and analysis methods, more and more people are worried that once personal health data is leaked, it may lead to serious consequences. Blockchain technology enables multi-signature private keys, encryption technology, and secure multi-party computing technology to prevent such situations from occurring. When the data is hashed and placed on the blockchain, digital signature technology is used to allow only authorized people to access the data. The private key ensures data privacy and can be shared with authorized research institutions. The data is uniformly stored on the decentralized blockchain, and data analysis can be performed without accessing the original data. This can not only protect the privacy of the data, but also safely provide it to global scientific research institutions and doctors for sharing. The basic health database will bring great convenience to solve sudden and difficult diseases in the future.
5. Data circulation: Blockchain protects data-related rights and interests
For individuals or institutions’ valuable data assets, blockchain can be used to register them, and transaction records are recognized and transparent by the entire network. , traceable, clarifying the source, ownership, use rights and circulation path of big data assets, which is of great value to data asset transactions.
On the one hand, blockchain can eliminate the threat of intermediaries copying data and help establish a trustworthy data asset trading environment. Data is a very special commodity, which is essentially different from ordinary commodities. It mainly has characteristics such as unclear ownership and "it is owned after seeing it and copying it". This also determines that the transaction method using traditional commodity intermediaries cannot meet the needs of data. Share, exchange and trade. Because the intermediary center has the conditions and ability to copy and save all the data flowing through it, this is extremely unfair to the data producers. This threat cannot be eliminated by relying on promises alone, and the existence of this threat has also become a huge obstacle to the flow of data. Based on decentralized blockchain, it can eliminate the threat of data copying by intermediary centers and protect the legitimate rights and interests of data owners.
On the other hand, blockchain provides a traceable path and can effectively solve the problem of data verification. The blockchain jointly participates in the calculation and recording of data through multiple nodes participating in calculations in the network, and mutually verifies the validity of their information. It can not only prevent information counterfeiting, but also provide a traceable path. By stringing together the transaction information of each block, a complete list of transaction details is formed. The ins and outs of each transaction are very clear and transparent. In addition, when people have doubts about the "value" of a certain block, they can easily review historical transaction records to determine whether the value is correct, and identify whether the value has been tampered with or recorded incorrectly.
Everything is guaranteed on the blockchain, and big data will naturally become more active.
The tokens of crowdfunding projects on the Biying China platform are all developed based on blockchain technology, and relevant information will be recorded on the blockchain.

⑻ What is the development trend of blockchain?

Since blockchain is going to become the future development trend, blockchain technology definitely has its own advantages over traditional technology.
1. Decentralization.
The core advantage of blockchain technology is that it does not require a traditional centralized organization. In a distributed system, it does not rely on point-to-point transactions, coordination and collaboration of a certain credit center, thus avoiding the need for central banks.Issues such as data security, collaboration efficiency and risk control that are common in centralized organizations.
2. High safety.
In blockchain technology, data is difficult to tamper with. The database recording transactions can be accessed by anyone. In this transparent and open model, everyone can act as a supervisor. Everyone can see any changes in the data at a glance, which is more secure than traditional technology.
3. More reliable.
Blockchain technology connects multiple nodes in different places. The nodes in the blockchain interact through point-to-point communication protocols. Different nodes can be used by different developers using different programming languages ​​while ensuring consistent communication protocols. , different versions of full nodes to process transactions.
To put it simply, when a node encounters network problems, hardware failures, software errors, or is controlled by hackers, it will not affect the operation of other participating nodes and the system.
So compared to traditional technology, blockchain is more reliable.
So I firmly believe that the application of blockchain must be the future development trend.

⑼ The future development prospects of blockchain

1. Blockchain has become the forefront of global technological development and opened up a new track for international competition. Blockchain will become a new key infrastructure to further accelerate the development of the digital economy, lead a new round of global technological change and industrial change, and become the "source" of technological innovation and model innovation. The world's major developed countries will further pay attention to blockchain technology, intensively introduce relevant policy plans, increase industrial support and guidance, and enhance the competitiveness of their country's blockchain technology and industry.
2. The digital currency bubble gradually cools down. With the spread and popularization of the concept of blockchain technology, more and more people will realize that Bitcoin is not the same as blockchain, and various air coins will be gradually eliminated. Blockchain technology innovation will return to a more rational track. Technical features such as decentralization, multi-party collaboration, and anti-calculation tampering will be highly valued by relevant industries. Some industries with strong innovation capabilities will continue to emerge with blockchain applications that have been transformed based on industry characteristics.
