2. Blockchain technology development status and prospects

Blockchain technology development status and prospects
Blockchain technology originated in 2008 under the pseudonym "China The foundational paper "Bitcoin: A Peer-to-Peer Electronic Cash System" published by scholar Satoshi Nakamoto on the cryptography mailing group. In the past two years, the research and application of blockchain technology have shown explosive growth. It is considered to be the fifth disruptive innovation in the computing paradigm after mainframes, personal computers, the Internet, and mobile/social networks. It is also the evolution of human credit. The fourth milestone in history after blood relatives credit, precious metal credit, and central bank banknote credit. Blockchain technology is the prototype of the next generation of cloud computing. It is expected to completely reshape the form of human social activities like the Internet and realize the transformation from the current information Internet to the value Internet. Technical characteristics of blockchain

Blockchain has the characteristics of decentralization, time series data, collective maintenance, programmability, security and trustworthiness. Decentralization: The processes of verification, accounting, storage, maintenance and transmission of blockchain data are all based on the distributed system structure. Pure mathematical methods are used instead of central institutions to establish trust relationships between distributed nodes, thus forming a decentralized system. Centralized and trustworthy distributed system; Time series data: Blockchain uses a chain block structure with timestamps to store data, thereby adding a time dimension to the data and having strong verifiability and traceability; Collective maintenance: The blockchain system uses specific economic incentive mechanisms to maintainAll nodes in the distributed system can participate in the verification process of data blocks (such as the "mining" process of Bitcoin), and select specific nodes to add new blocks to the blockchain through the consensus algorithm; Programmable: Zone Blockchain technology can provide a flexible script code system to support users to create advanced smart contracts, currencies or other decentralized applications; safe and trustworthy: Blockchain technology uses asymmetric cryptography principles to encrypt data, while using distributed The powerful computing power formed by the consensus algorithm such as the workload proof of each node in the system can resist external attacks and ensure that the blockchain data cannot be tampered with or forged, so it has high security. Blockchain and Bitcoin Bitcoin is by far the most successful blockchain application scenario. Blockchain technology has solved the double payment problem and Byzantine Generals problem that the Bitcoin system has long faced in the field of digital cryptocurrency. Different from the credit endorsement mechanism of traditional central institutions (such as central banks), the Bitcoin blockchain forms software-defined credit, which marks a fundamental change from centralized national credit to decentralized algorithmic credit. In recent years, Bitcoin has relied on its first-mover advantage to form a complete ecosystem and industry chain covering issuance, circulation and financial derivatives markets. This is also the main reason why it has occupied the vast majority of the digital cryptocurrency market share for a long time. The development context and trends of blockchain
Blockchain technology is a universal underlying technology framework that can bring profound changes to various fields such as finance, economy, technology and even politics. According to the current development trend of blockchain technology, blockchain technology will experience the blockchain 1.0 model with programmable digital encryption currency system as the main feature, the blockchain 2.0 model with programmable financial system as the main feature, and the blockchain 2.0 model with programmable financial system as the main feature. The blockchain 3.0 model is characterized by a programmable society. However, the above-mentioned models are actually developing in parallel rather than in an evolutionary manner. The digital cryptocurrency system of the blockchain 1.0 model is still far from mature, and is actually farther and more difficult from its vision of global currency integration. At present, the blockchain field has shown an obvious development trend driven by technological and industrial innovation, and relevant academic research is seriously lagging behind and urgently needs to be followed up. Basic models and key technologies of blockchain
Generally speaking, a blockchain system consists of a data layer, a network layer, a consensus layer, an incentive layer, a contract layer and an application layer. Among them, the data layer encapsulates the underlying data blocks and related data encryption and timestamp technologies; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates various consensuses of network nodes Algorithm; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, which is the programmable feature of the blockchain. The foundation; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamp, the consensus mechanism of distributed nodes, andEconomic incentives for consensus computing power and flexible programmable smart contracts are the most representative innovations of blockchain technology. Application Scenarios of Blockchain Technology
Blockchain technology can not only be successfully used in the field of digital cryptocurrency, but also has a wide range of application scenarios in economic, financial and social systems. According to the current status of blockchain technology applications, this article broadly summarizes the current main applications of blockchain into six scenarios: digital currency, data storage, data authentication, financial transactions, asset management and election voting: Digital currency: Bitcoin It represents a digital currency that is essentially generated by a distributed network system, and its issuance process does not rely on a specific centralized institution. Data storage: The characteristics of blockchain such as high redundant storage, decentralization, high security and privacy protection make it particularly suitable for storing and protecting important private data to avoid attacks caused by centralized institutions or improper permission management. Massive data loss or breach. Data authentication: Blockchain data is time-stamped, jointly verified and recorded by consensus nodes, and cannot be tampered with or forged. These characteristics make the blockchain widely used in various data notarization and audit scenarios. For example, blockchain can permanently and securely store various licenses, registration forms, licenses, certificates, certifications and records issued by government agencies. Financial transactions: Blockchain technology has a very high degree of compatibility with financial market applications. Blockchain can spontaneously generate credit in a decentralized system and can establish a financial market without credit endorsement by a central institution, thereby realizing "financial disintermediation" to a large extent; at the same time, blockchain can be used to automate smart contracts and trustworthy transactions. The characteristics of programming can greatly reduce costs and improve efficiency. Asset management: Blockchain can realize the confirmation, authorization and real-time monitoring of tangible and intangible assets. Intangible asset management has been widely used in intellectual property protection, domain name management, points management and other fields; tangible asset management can be combined with Internet of Things technology to form "digital smart assets" to achieve distributed authorization and control based on blockchain. Election voting: Blockchain can implement applications such as political elections and corporate shareholder voting in a low-cost and efficient manner. At the same time, voting can be widely used in fields such as gambling, prediction markets, and social manufacturing. Existing issues with blockchain technology
Security threats are the most important issues faced by blockchain so far. Among them, blockchains based on the PoW consensus process mainly face the 51% attack problem, that is, nodes have the ability to successfully tamper and forge blockchain data by controlling more than 51% of the computing power of the entire network. Other issues include the potential threats of emerging computing technologies to crack asymmetric encryption mechanisms and privacy protection issues. The efficiency of blockchain is also an important factor restricting its application. Blockchain requires each node in the system to save a data backup, which is extremely difficult to store the growing mass of data. Although lightweight nodes can partially solve this problem, industrial-grade solutions suitable for larger scales still need to be developed. The Bitcoin blockchain can currently only process 7 transactions per second, and transaction confirmation time is generally 10 minutes, which greatly affectsThis limits the application of blockchain in high-frequency trading scenarios in most financial systems. The PoW consensus process highly relies on the computing power contributed by the blockchain network nodes. These computing powers are mainly used to solve SHA256 hashes and random number searches. In addition, they do not produce any actual social value. Therefore, these computing powers are generally considered Resources are "wasted", and a large amount of power resources are also wasted. How to effectively pool the network computing power of distributed nodes to solve practical problems is an important issue that blockchain technology needs to solve. As a decentralized distributed system, the blockchain network will inevitably have game relationships of competition and cooperation between its nodes during the interaction process, such as the block interception attack game of the Bitcoin mining pool. The blockchain consensus process is essentially a crowdsourcing process. How to design an incentive-compatible consensus mechanism so that self-interested nodes in a decentralized system can spontaneously implement the verification and accounting of block data, and improve the efficiency of non-profit organizations within the system. The cost of rational behavior to suppress security attacks and threats is an important scientific issue to be solved in blockchain. Smart Contracts and Blockchain Technology
Smart contracts are a set of scenario-responsive programmed rules and logic. They are decentralized, trustworthy and shared program codes deployed on the blockchain. Usually, after the smart contract is signed by all parties, it is attached to the blockchain data (such as a Bitcoin transaction) in the form of program code, and is recorded in a specific block of the blockchain after being propagated through the P2P network and verified by nodes. . Smart contracts encapsulate a number of predefined states and transition rules, scenarios that trigger contract execution (such as reaching a specific time or occurrence of a specific event, etc.), response actions under specific scenarios, etc. The blockchain can monitor the status of smart contracts in real time, and activate and execute the contract by checking external data sources and confirming that specific trigger conditions are met. Smart contracts are of great significance to blockchain technology. On the one hand, smart contracts are the activators of the blockchain, giving flexible and programmable mechanisms and algorithms to the static underlying blockchain data, and laying the foundation for building programmable financial systems and social systems in the blockchain 2.0 and 3.0 eras. On the other hand, the automation and programmable characteristics of smart contracts enable it to encapsulate the complex behavior of each node in the distributed blockchain system and become a software agent robot in the virtual world composed of blockchain, which helps Promote the application of blockchain technology in various distributed artificial intelligence systems, allowing the construction of various decentralized applications (Decentralized applications, Dapp), decentralized autonomous organizations (Decentralized Autonomous Organization, DAO), and Decentralized Autonomous Corporation (DAC) or even Decentralized Autonomous Society (Decentralized AutonomousSociety, DAS) becomes possible. The main development trend of blockchain and smart contract technology is from automation to intelligence. The essential logic of various existing smart contracts and their applications is mostly based on "IF-THEN" type conditional response rules based on predefined scenarios, which can meet the current needs of automated transactions and data processing. Future smart contracts should have "WHAT-IF" deductions based on unknown scenarios, computational experiments, and a certain degree of autonomous decision-making functions, thereby achieving a leap from current "automated" contracts to true "smart" contracts. Blockchain-driven parallel society
In recent years, a parallel society based on CPSS (Cyber-Physical-SocialSystems) has emerged. Its core and essential feature is virtual-real interaction and parallel evolution. Blockchain is one of the infrastructures for realizing CPSS parallel society. Its main contribution is to provide a set of effective decentralized data structures, interaction mechanisms and computing models for distributed social systems and distributed artificial intelligence research. And it has laid a solid data foundation and credit foundation for the realization of a parallel society. As far as the basis of data is concerned, management scientist Edward Deming once said: Everyone except God must speak with data. However, in centralized social systems, data is usually in the hands of a "few people" such as governments and large enterprises. It "speaks" for a few people, and its fairness, authority and even security may not be guaranteed. Blockchain data is stored in highly redundant distributed nodes and is in the hands of "everyone", enabling true "data democracy". In terms of the basis of credit, centralized social systems will inevitably have the characteristics of "Mertonian systems" due to their high engineering complexity and social complexity, that is, uncertainty, diversity and complexity, which are the center of social systems. Institutions and rule makers may behave dishonestly due to individual interests; blockchain technology helps realize a software-defined social system. Its basic idea is to eliminate centralized institutions and convert unpredictable behaviors into programmed codes of smart contracts. The form is deployed and solidified in the blockchain data in advance, and cannot be forged or tampered with afterwards and is executed automatically. This can, to a certain extent, transform the "Merton" social system into a "Newton" that can be fully observed, actively controlled, and accurately predicted. "Social system. The ACP (Artificial Societies, Computational Experiments and Parallel Execution) method is the only systematic and complete research framework in the field of parallel society management so far. It is the logical extension and logical extension of complexity science in the parallel social environment in the new era. Innovation. The ACP method can be naturally combined with blockchain technology to achieve blockchain-driven parallel social management. First of all, the blockchain’s P2P networking, distributed consensus collaboration and contribution-based economic incentives are themselvesNatural modeling of distributed social systems, where each node will act as an autonomous and autonomous agent in the distributed system. With the improvement of the blockchain ecosystem, the consensus nodes of the blockchain and increasingly complex and autonomous smart contracts will form DAC and DAO in specific organizational forms by participating in various forms of Dapp, and ultimately form DAS, which is the ACP. artificial society. Secondly, the programmable nature of smart contracts allows the blockchain to carry out various "WHAT-IF" types of virtual experimental design, scenario deduction and result evaluation. Through this computational experiment process, optimal decisions are obtained and executed automatically or semi-automatically. Finally, the smart assets formed by the combination of blockchain and the Internet of Things make it possible to connect the real physical world and virtual cyberspace, and can achieve collaborative optimization of social management and decision-making through virtual-real interaction and parallel tuning of real and artificial social systems. It is not difficult to predict that in the future, when all physical assets in the real physical world are registered as smart assets on the chain, the blockchain-driven parallel society will arrive.

5. Blockchain Era: Transformation from Information Internet to Value Internet

Guosen’s perspective

Guosen Overseas Group’s perspective:

Internet Up to now, its main function is to allow information to circulate on the Internet, and information is spread by copying (A is copied to B). The "ledger" constructed by the blockchain is open, transparent, non-tamperable, peer-to-peer interconnected, and easy to trace, and builds an infrastructure based on a trust mechanism to allow the value of digital assets to circulate efficiently on the Internet, and digital assets occur on the Internet. Transfer of value (transfer from A to B, rather than copying from A to B). We are optimistic about the future of blockchain. However, the most important achievement of blockchain at this stage is the evangelism of ideas. Its emergence allows the market to see the shortcomings of the "Internet of Information" and the trend of the "Internet of Value".

Comments

The relationship between blockchain and Bitcoin

Explaining blockchain, there is no way around Bitcoin. The "invention" of Bitcoin has proven the feasibility of blockchain technology. Bitcoin is not the entirety of blockchain technology, but only one of its applications. Without Bitcoin, it’s possible that blockchain wouldn’t have happened, or at least not anytime soon.

The origin of the word "blockchain" is the "chain of blocks" in the original English version of the Bitcoin white paper. When translated into Chinese, the word "blockchain" is used. As the focus of Bitcoin mining shifts to China, the Chinese market has become the main battlefield for blockchain and Bitcoin. The English domestic market of blockchain is written as "blockchain", which has become a proper noun for the entire blockchain technology in the world. (Noun evolution path: chain of blocks - blockchain - blockchain).

The total amount of Bitcoin is limited, stimulating market speculation

Whether Bitcoin is regarded as a commodity or currency, due to its limited total amount, it stimulates market speculation on Bitcoin. Price, referred to as currency speculation. According to the Bitcoin generation mechanism, the total number of Bitcoins is 21 million..

Bitcoin is the reward after a new block is connected. A block is generated every 10 minutes. A certain number of Bitcoins are rewarded for each block generated. 50 are rewarded in the first four years. The number of Bitcoin rewards is halved every four years, so the total number of Bitcoins is 21 million. Calculation method: {50 X 6 X 24 X 365} X 4 X {1+1/2+. . . . . (1/2)n}=21 million (2.1*107).

Technical principles of blockchain

Blockchain timestamps all transactions through random hashing and merges them into an ever-extending random hash-based, working The proof-of-work chain is used as a transaction record. Unless all the proof-of-work is completed again, the transaction record cannot be changed. There are three steps to form a new block:

1. The miner packages the four parts of the "ledger, the header of the previous block, the timestamp, and the random number sequence X" within a period of time into a block;

2. Through a large number of calculations, the miner adjusts the random number sequence X of the block, generates the composite required hash value, and obtains Bitcoin rewards.

3. Miners connect the new block with the previous block to form a new blockchain.

The number of patents is an important indicator for quantifying blockchain companies at this stage

The global blockchain industry is still in the early stages of development. Most companies are in the conceptual design stage and have no commercialized products. It is difficult for the outside world to objectively evaluate the pros and cons of startup companies. We believe that the number of blockchain invention patents can reflect the potential of each company and is an important indicator for distinguishing blockchain companies through quantitative means at this stage.

Investment advice: Based on the fundamentals of the company, focus on the value of the Internet in the blockchain era

With the development of the Internet to the present, its main function is to allow information to circulate on the Internet, and information can be copied. propagation method (A is copied to B). The "ledger" constructed by the blockchain is open, transparent, non-tamperable, peer-to-peer interconnected, and easy to trace, and builds an infrastructure based on a trust mechanism to allow the value of digital assets to circulate efficiently on the Internet, and digital assets occur on the Internet. Transfer of value (transfer from A to B, rather than copying from A to B). We are optimistic about the future of blockchain. However, the most important achievement of blockchain at this stage is the evangelism of ideas. Its emergence allows the market to see the shortcomings of the "Internet of Information" and the trend of the "Internet of Value".

Realizing the "Internet of Value" requires large-scale application implementation, not a single technology. At this stage, blockchain is still in its early stages of development. We are optimistic about the future of blockchain, but we do not overestimate the present of blockchain.

In the Hong Kong stock market, there are many companies involved in blockchain. Based on the company's fundamentals and the number of blockchain patents, we recommend Tencent Holdings and Launch Technology, maintaining performance forecasts and recommendation ratings.

Tencent (0700.HK): WeThe company's revenue growth rate is expected to be 22% and 22% in 2019-2020, and its net profit growth rate is 23% and 16%, of which NON-GAAP profit growth rate is 15% and 16%. The EPS corresponding to 2019 and 2020 are HK$10.4 and 12.1, and the target valuation range is maintained at 380 to 400 yuan, corresponding to 31 times to 33 times PE in 2020. The overweight rating is maintained.

Launch Technology (2488.HK): We predict that the company’s revenue growth rate from 2019 to 2020 will be 9.7% and 12.2%, and its net profit growth rate will be 69% and 29%, corresponding to EPS of 0.32, 0.42 Hong Kong dollars. We maintain a "buy rating" and recommend a reasonable valuation of HK$8-9, corresponding to 25-28 times PE in 2019.

Risk warning

1. Blockchain concepts cannot be turned into products. 2. The emergence of new technologies causes the blockchain to be falsified. 3. The profits from the company’s existing business cannot support the long-term R&D investment in blockchain.

6. The development status of the global blockchain industry in 2021 is based on both a global perspective and a domestic perspective

As an emerging information technology, blockchain will continue to develop in-depth in 2021, and in regulatory policies There have been continuations and breakthroughs in terms of technology and applications, and related aspects such as NFT, Metaverse and central bank digital currency are ushering in an explosion.

In the era of digital economy, it is particularly important to grasp the development and development trends of blockchain. This article will start from two perspectives: a global perspective and a domestic perspective

(1) Global perspective: the blockchain industry is growing in leaps and bounds, and the track in emerging fields is hot

1. Blockchain has become a multinational strategy, and cryptocurrency policies are polarized

2. Blockchain spending grows, with banking industry spending leading

Blockchain and other distributed ledger technologies have shown great potential in improving the efficiency of business operations and creating new ways of delivering value, across industries and Companies are implementing these technologies and integrating them into existing infrastructure and industry plans. According to Statista, global spending on blockchain solutions is expected to reach $6.6 billion in 2021. Forecasts indicate that spending on blockchain solutions will continue to grow in the coming years, reaching nearly $19 billion by 2024

3. NFT, cryptocurrency, and the metaverse are booming

In 2021, new models and new business formats based on blockchain will continue to emerge. Among the hot words of 2021 announced by Collins Dictionary, NFT ranked first on the hot word list, and the words Metaverse and Crypto were also shortlisted for the list.

Starting in March 2021, NFT has experienced explosive growth. The full name of NFT is Non-Fungible Token, and the Chinese expression is non-fungible token. NFT is a data unit stored on the blockchain. It uses photos, videos, audios and other types of digital files as underlying assets, and supports the verification of the authenticity and uniqueness of the underlying assets.

4. More than 90% of the world’s economies are exploring central bank digital currencies

(2) Domestic perspective: The blockchain industry is making steady progress, and the digital renminbi has achieved gratifying results

1. Promote the development of blockchain technology and rectify virtual currency transactions and "mining" activitiesMove

2. The number of registered blockchain companies continues to rise, and the industry is about to enter a "steady recovery period"

3. The digital renminbi is in full bloom, and three major challenges need to be overcome

7. When will the national standard for blockchain technology be completed

my country has begun to establish a national standard for blockchain to promote it from the top-level design The construction of the blockchain standard system is expected to be completed by the end of 2019 at the earliest.

In this regard, Zhao Wu, founder of Beijing Huashun Xin'an Technology Co., Ltd., also said that although blockchain has disruptive technological potential, we must realize that blockchain The chain is still in its infancy and is far from reaching the stage where it can disrupt the world.

Yu Kequn emphasized that an independent and controllable blockchain network is not technically controlled by others, but can also promote the healthy development of the blockchain. Security is the future life of the blockchain, and only its own security can bring blockchain technology to fruition. This requires us to pay equal attention to the development of its security attributes while developing blockchain technology, and even develop it ahead of time.

In this regard, Li Ming also said that an important part of the standard is the standard of information security, which also shows the importance of security for blockchain technology. He also pointed out that the formulation of blockchain standards does not mean that it will rapidly promote the development of the industry, but rather gives certain guidance to the industry. Previously, China had suffered a lot in terms of international intellectual property rights and standards. In terms of blockchain, China has now formed more than 200 patents in international blockchain, and has even stood at the forefront of the world's technology. Therefore, we also need to firmly grasp our right to speak.
