『一』 It’s 2021, what will be the development trend of my country’s blockchain technology in the future
Domestic blockchain technology has been conceptualized a few years ago. Now it has been widely used in actual business scenarios, such as the rice we eat, the QR code on the packaging
Traceability is the application of blockchain technology. Companies like Shanghai Wanglian Technology entered the market earlier and are currently developing very well.
『二』What is blockchain technology and what are the core components of blockchain technology
From a technical point of view and an architectural point of view, I will tell you about it in popular language. , my understanding of blockchain.
What exactly is blockchain? Block chain, in a word, blockchain is a storage system, and the storage system is more detailed. Block chain is a distributed storage system without an administrator, and each node owns all data.
What do common storage systems look like?
First, let’s take a look at how to ensure high availability?
Ordinary storage systems usually use "redundancy" to solve high availability problems. As shown in the figure above, if the data can be copied into several copies and redundantly spread to multiple places, high availability can be ensured. If the data in one place is down, there will still be data in another place. For example, the master-slave cluster of MySQL has this principle, and the RAID of the disk also has this principle.
Two points that need to be emphasized here are: data redundancy often causes consistency problems
1. For example, in the master-slave cluster of MySQL, there will actually be a delay in reading and writing. Sometimes, it actually means that there is inconsistency between reading and writing for a short period of time. This is a side effect of data redundancy.
2. The second point is that data redundancy often reduces writing efficiency, because data synchronization also consumes resources. If you look at single-point writing, if two slave libraries are added, the writing efficiency will actually be affected. Ordinary storage systems use redundancy to ensure high data availability.
Then the second question is, can an ordinary storage system perform multiple writes?
The answer is yes, for example, take this picture as an example:
In fact, MySQL can do a master-slave synchronization of dual masters, a master-slave synchronization of dual masters, and two nodes. , and can be written at the same time. If you want to build a multi-machine room and multi-active data center, in fact, multi-machine room and multi-active data center also requires data synchronization. What should be emphasized here is that multi-point writing often leads to consistency issues of write-write conflicts. Taking MySQl as an example, assuming that the attribute of a table is an auto-increment ID, then the data in the database is now 1234, then one of the nodes When writing, a piece of data is inserted, it may become 5. Then these 5 pieces of data are synchronized to another master node. Before the synchronization is completed, if another writing node also inserts a piece of data, it will also generate A piece of data with an auto-incrementing ID of 5 is obtained. Then, after generating,Synchronize to another node, and then when the synchronized data arrives, it will conflict with the two local 5s, and the synchronization will fail, which will cause write consistency conflicts. This problem will occur if there are multiple writes.
How to ensure consistency when writing multiple points?

『三』What is the development history of blockchain technology
Which came first, Bitcoin or blockchain? When Bitcoin was first born, there was no concept of "blockchain". People used bitcoin (lowercase b) to represent Bitcoin, and Bitcoin (capital B) to represent its underlying technology, which is what we now call blockchain technology. In 2015, after The Economist published its cover article "Blockchain Technology Reshaping the World," blockchain technology set off a financial technology craze around the world. Major financial institutions and banks around the world rushed to study blockchain technology. In 2016 alone, billions of dollars were invested in blockchain-related companies. In September 2017, the Chinese government website (www.gov.cn) published an article "my country's blockchain industry is expected to be at the forefront of the world", publicly supporting the development of blockchain technology and popularizing blockchain technology to 1.3 billion Chinese people . The application of blockchain in real economic fields such as finance, insurance, retail, and notarization has begun to accelerate.
『四』What are the application fields of blockchain technology?
Application fields: financial field, Internet of Things and logistics field, public service field, digital copyright field, insurance field, public welfare field .
Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered a promising application direction of blockchain.
Blockchain is closely related to people’s production and life in the fields of public management, energy, transportation, etc. However, the centralized nature of these fields also brings some problems, which can be transformed with blockchain.

『五』What is the current status of China’s blockchain
The development of China’s blockchain industry in 2019 Rapidity is mainly reflected in the following points:
First, high-level national strategic guidance and support create a good policy environment. According to incomplete statistics, in the first half of 2019, more than 23 provinces and cities across the country issued more than 112 policy messages involving blockchain. High-level government officials emphasized that the application of blockchain technology plays an important role in technological innovation and industrial transformation, and supported the accelerated development of blockchain technology and industrial innovation.
In addition, market supervision policies regarding blockchain have also gradually improved. On the one hand, strict vigilance and testing are carried out for virtual currency transactions and services; on the other hand, related industries with blockchain applications The regulatory system is also being further constructed and improved to provide a strong guarantee for industrial blockchain projects to deeply serve the real economy. The market has become more standardized and the industrial environment has gradually become clearer. In addition, support for technological breakthroughs and talent encouragement has also been provided through the establishment of blockchain Industrial parks, blockchain special investment funds and other means will subsidize technological innovation and talent introduction to promote the development of the blockchain industry.
Second, domestic enterprises actively participate in the research and development and application of blockchain technology and carry out blockchain strategic layout. For example, e-commerce giants such as Alibaba use blockchain technology in areas such as product traceability and cross-border settlement. JD.com uses a transparent supply chain system to combat counterfeit and shoddy products. Tencent focuses on the development of applications in financial fields such as electronic invoices.
『Lu』What is blockchain technology? What exactly is blockchain?
In a narrow sense, blockchain is a way to store data in a chronological order. A chained data structure composed of blocks connected in sequence, 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.
[Infrastructure]
Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer composition. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms; 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, and is the core of the blockchain The basis of programmable features; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.
Extended information:
[Blockchain core technology]
Blockchain mainly solves the trust and security issues of transactions, so it addresses this issueFour technological innovations are proposed:
1. Distributed ledger, which means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they All can participate in supervising the legality of transactions and can also jointly testify for them.
The uniqueness of blockchain's distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally stores The data is divided into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and has equal status, relying on the consensus mechanism to ensure the consistency of storage, while traditional distributed storage generally synchronizes data to other backup nodes through the central node.
No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.
2. Asymmetric encryption and authorization technology. Transaction information stored on the blockchain is public, but account identity information is highly encrypted and can only be accessed with authorization from the data owner. , thus ensuring data security and personal privacy.
3. The consensus mechanism is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.
The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be the computing power and the number of shares. Or other characteristic quantities that the computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result.
4. Smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.
In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.
