⑴ Do you know the three important stages in the history of blockchain development?

As blockchain technology matures, blockchain technology has made great achievements in the financial field. Significant results. Whether they are investors, practitioners in related financial fields, or technology practitioners, they are all very concerned about blockchain. Many people or platforms have begun to devote themselves wholeheartedly to it, using blockchain technology to create a new financial system, and have achieved impressive results.

If you have studied blockchain, maybe you have a deeper understanding of blockchain. Since the birth of blockchain, in terms of applications, It has gone through three stages of change. There have been important developments and inventions at every stage of blockchain technology, and blockchain technology has only existed for a small portion of the Internet's time, so there are likely still important developments to come.

The first technical stage

Bitcoin has been running since 2019. The main technology supporting the Bitcoin system includes hashing Technologies such as functions, distributed ledgers, blockchain, asymmetric encryption, and workload proof constitute the initial version of the blockchain.

At present, blockchain technology is not yet mature, the conservative tendency within many organizations is still obvious, and the use of centralized technology and processes in the market to make profits Intermediaries that collect revenue, equipment providers are also hyping up the concerns it may bring.

Second market phase

In early 2013, the price of Bitcoin began rise. In November of the same year, a U.S. Senate hearing clarified the legality of Bitcoin, and the price of Bitcoin rose sharply. But at this time, the blockchain has not yet reached the mainstream social and economic foundation, but its price has risen beyond expectations. At this time, the market opened up the visibility of Bitcoin and blockchain, but despite this, they still did not gain universal acceptance to a certain extent.

The third mainstream stage

Bitcoin, which is an alternative to the mainstream economy, began to recover. Market demand increased and transaction scale expanded rapidly. It also opened up the bull market of 2016-2017. . The enrichment effect of Bitcoin and the spillover effect caused by the congestion of the Bitcoin network have led to the explosive and crazy growth of other virtual currencies and various blockchain applications. At this time, it triggered a crazy global pursuit to make Bitcoin and blockchain a complete global vision.

In 2020, although the epidemic has dealt an important blow to our economy, the hot development of Bitcoin and blockchain tells us that they existIt creates opportunities and drives related development. Just like the recent price of Bitcoin is close to 30,000 US dollars, such a market has brought surprises to many people, and it has also promoted the development of exchanges. After all, exchanges are the only way to buy Bitcoins. Its popularity is also It has brought good profits to exchanges, such as Huobi and Saturn Exchange, which have refreshed their historical trading volumes many times due to this bull market. In fact, no matter which industry develops, it will always drive multiple industries. After all, many things are always closely related.

⑵ How to define blockchain and what are the application scenarios of blockchain?

Nowadays, many people think that blockchain is a universal technology that can do anything, which is somewhat different. Blockchain technology is a myth!
Regarding the definition of blockchain technology, American scholar Melanie Swann defined blockchain technology as an open, transparent and decentralized technology in her book "Blockchain: A New Economic Blueprint and Introduction" database.

Definition of Blockchain: Narrow VS Broad

As for the application scenarios of blockchain technology, it is natural to combine the differences between blockchain and other technologies. In terms of system characteristics.

Blockchain technology features include:

Blockchain is a global A database storage system that can be operated collaboratively in various places is different from traditional database operations where read and write permissions are in the hands of a company or a centralized authority (a characteristic of centralization). Blockchain believes that anyone with the ability to set up a server can participate. Nuggets from all over the world have deployed their own servers locally and connected to the blockchain network to become a node in this distributed database storage system; once joined, the node enjoys exactly the same rights as all other nodes and obligations (decentralized, distributed characteristics).

At the same time, people who provide services on the blockchain can perform read and write operations on any node in the system. In the end, all nodes around the world will complete the process again and again according to a certain mechanism. Synchronize in sequence to achieve complete consistency of data in all nodes in the blockchain network.

At the beginning of this year, the term blockchain began to enter everyone’s lives. From national leaders to aunts who dance square dances, everyone knows this term. This term is widely known by Bit Brought by coins.

As we all know, the first few dozen bitcoins could only be exchanged for one pizza. At its peak, it was more than 20,000 US dollars each, which has skyrocketed by more than a thousand times, which has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering into everyone's life, and many people have joined the ranks of currency speculation. I often hear people say that if you buy the right currency a hundred times, a bicycle will become a sports car, and one coin will turn a young model. You can imagine how many of them are involved. Attractive.

2008At the beginning, various games applying blockchain technology also became popular, such as development games (Network Letts Dog, 360 Block Cat), mining games (NetEase Planet, Virtual Earth, Gongxinbao), these are distinguished by The name of blockchain attracts everyone to join, and of course there are some that are really reliable, which requires everyone to identify carefully.

Blockchain is a distributed ledger (database) that connects data blocks in an orderly manner and cryptographically ensures that it cannot be tampered with or forged. technology. In layman's terms, blockchain technology can achieve openness, transparency, non-tampering, non-forgery, and traceability of all data information in the system without the need for third-party endorsement. As an underlying protocol or technical solution, blockchain can effectively solve the problem of trust and realize the free transfer of value. It has broad prospects in the fields of digital currency, financial asset transaction settlement, digital government affairs, and certificate deposit and anti-counterfeiting data services.

Digital currency

After experiencing physical objects, precious metals, banknotes and other forms, digital currency has become the development direction of the digital economy era. Compared with physical currency, digital currency has the characteristics of easy portability and storage, low circulation cost, convenient use, easy anti-counterfeiting and management, breaking geographical restrictions, and better integration.

Bitcoin technically implements an electronic cash system in which both parties to the transaction can directly transfer funds to each other without the need for third-party transfer or arbitration. In June 2019, the Internet giant Facebook also released a white paper on its cryptocurrency Libra. Whether it is Bitcoin or Libra, the underlying technology they rely on is blockchain technology.

my country began the development of central bank digital currency as early as 2014. my country's digital currency DC/EP adopts a two-tier operating system: the central bank does not directly issue digital currency to the public. Instead, the central bank redeems the digital currency to various commercial banks or other legal operating institutions, and then these institutions exchange it for public supply. its use. In early August 2019, the central bank held a video conference on work for the second half of the year. The meeting called for accelerating the pace of research and development of the national legal digital currency.

Financial asset transaction settlement

Blockchain technology naturally has financial attributes, and it is causing disruptive changes in the financial industry. In terms of payment and settlement, under the blockchain distributed ledger system, multiple market participants jointly maintain and synchronize a "general ledger" in real time. Payment, clearing, and settlement that currently take two or three days can be completed in just a few minutes. tasks, reducing the complexity and cost of cross-bank and cross-border transactions. At the same time, the underlying encryption technology of the blockchain ensures that participants cannot tamper with the ledger, ensuring that transaction records are transparent and safe. Regulators can easily track transactions on the chain and quickly locate high-risk capital flows. In terms of securities issuance transactions, the traditional stock issuance process is long, costly and complicated. Blockchain technology can weaken the role of underwriting institutions and help all parties establish fast and accurate information exchange.In the shared channel, the issuer handles the issuance on its own through smart contracts, and the regulatory authorities conduct unified review and verification. Investors can also bypass intermediaries and conduct direct operations. In terms of digital bills and supply chain finance, blockchain technology can effectively solve the financing difficulties of small and medium-sized enterprises. It is difficult for current supply chain finance to benefit small and medium-sized enterprises in the upper reaches of the industrial chain, because they often do not have direct trade relations with core enterprises, and it is difficult for financial institutions to evaluate their credit qualifications. Based on blockchain technology, we can establish a consortium chain network covering core enterprises, upstream and downstream suppliers, financial institutions, etc. The core enterprises issue accounts receivable vouchers to their suppliers. After the bills are digitized and uploaded to the chain, they can be uploaded to the supplier Transfer between them, each level of supplier can realize the corresponding amount of financing with the digital bill certificate.

Digital Government Affairs

Blockchain can make data run and greatly streamline the service process. The distributed technology of blockchain can allow government departments to be centralized on one chain, and all service processes are delivered to smart contracts. As long as the service personnel pass the identity authentication and electronic signature in one department, the smart contracts can be automatically processed and transferred, and the subsequent steps can be completed in sequence. All approvals and signatures. Blockchain invoice is the earliest application of domestic blockchain technology. The tax department launched the "Tax Chain" platform for blockchain electronic invoices. The tax department, the issuer, and the payee join the "Tax Chain" network through unique digital identities, truly realizing "instant invoicing for transactions" and "instant reimbursement after invoicing" - in seconds Level invoicing and minute-level reimbursement accounting greatly reduce tax collection and management costs, and effectively solve problems such as data tampering, over-reporting of one ticket, and tax evasion. Poverty alleviation is another practical application of blockchain technology. Utilize the characteristics of openness, transparency, traceability, and non-tampering of blockchain technology to achieve transparent use, precise investment, and efficient management of poverty alleviation funds.

Evidence-based anti-counterfeiting

Blockchain can prove the existence of a file or digital content at a specific time through hash timestamps, and it is open, non-tamperable, and traceable. It provides perfect solutions for judicial forensics, identity certification, property rights protection, anti-counterfeiting and traceability, etc. In the field of intellectual property, the digital signature of blockchain technology and on-chain certificates can confirm the rights of text, pictures, audio and video, etc., and create and execute transactions through smart contracts, allowing creators to regain pricing power and preserve data formation in real time. The evidence chain covers the three major scenarios of rights confirmation, transaction and rights protection. In the field of anti-counterfeiting and traceability, blockchain technology can be widely used in various fields such as food and medicine, agricultural products, alcohol, and luxury goods through supply chain tracking.

Data services

Blockchain technology will greatly optimize existing big data applications and play a huge role in data circulation and sharing. In the future, the Internet, artificial intelligence, and the Internet of Things will generate massive amounts of data. The existing centralized data storage (computing model) will face huge challenges. Edge storage (computing) based on blockchain technology is expected to become a future solution. Furthermore, the blockchain’s non-tampering and traceability mechanism for data ensures the authenticity and high efficiency of the data.Quality has become the foundation for all data applications such as big data, deep learning, and artificial intelligence. Finally, blockchain can realize multi-party collaborative data calculations while protecting data privacy, and is expected to solve the problems of "data monopoly" and "data islands" and realize the value of data circulation. In response to the current blockchain development stage, in order to meet the blockchain development and application needs of general business users, many traditional cloud service providers have begun to deploy their own BaaS ("Blockchain as a Service") solutions. The combination of blockchain and cloud computing will effectively reduce enterprise blockchain deployment costs and promote the implementation of blockchain application scenarios. In the future, blockchain technology will also play an important role in many fields such as charity, insurance, energy, logistics, and the Internet of Things.

The three words "blockchain" were completely ignited during the Spring Festival that just passed. The limelight overshadowed everything. Some people said that this was the arrival of a new era. The past It has become a classic, and some people say that it is all hype and is ultimately a bubble.

In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, the third-party electronic signature platform eShanbao revealed the latest progress of blockchain applications to NewSeed.

Currently, blockchain technology is mainly used in e-signing products for certificate deposit and certificate issuance. The application scenarios include copyright protection and online signing. , web page forensics, phone recording, email storage of evidence, etc.

Take the rights protection of online works as an example. Since online rights protection generally adopts the method of collecting evidence after the fact, real-time confirmation of rights is not carried out in the process of evidence generation, so the entire confirmation process is difficult. The copyright process is time-consuming, difficult and costly to obtain evidence, and extremely difficult to prove and trace the source. It cannot meet the characteristics of rapid dissemination and large quantity of online works.

eShanbao's new intellectual property protection solution based on timestamp + blockchain starts from the user's real-name authentication and solidifies the information generated in the process in real time. Electronic data, and through the time source service synchronized with the National Time Service Center, online works are stamped with legally valid timestamps to prove that electronic files have not been tampered with in a certain period of time. Blockchain technology can establish point-to-point trust in the network, ensuring that all blockchain nodes can record complete copyright confirmation and transaction records, and can trace their origins, truly realizing anti-repudiation and anti-tampering, and realizing a kind of distribution. trust infrastructure.

Founder and CEO Jin Hongzhou believes that the application of decentralized blockchain technology has greatly improved the efficiency of data storage and certification, and The credibility of the identity of the parties reduces the cost of trust, but it cannot replace the original centralized public key encryption technology. The two should complement each other.status, through the combination of the two, to provide users with real-time and reliable confirmation solutions.

Next, e-Shanbao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage, Issuing certificates is only a relatively superficial application based on blockchain technology. It is the first step to implement blockchain technology, and the realization of real smart contracts is the second step. "Smart contracts cannot simply be understood as electronic contracts. They refer to a process, from the conclusion of the contract to the confirmation to the final execution." Jin Hongzhou explained.

From a technical perspective, blockchain is not a brand-new technology, but a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, and smart contracts. Specifically, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner.

Due to its advantages such as "decentralization", "distributed data storage", "traceability", "anti-tampering", and "openness and transparency", blockchain technology can effectively solve data problems. By establishing a trustworthy data management environment, we can prevent and avoid various data management problems such as data fraud, tampering, and loss, and promote the efficient sharing and application of data. In the process of practice and exploration, the application scope of blockchain technology continues to expand, especially in the field of public resource transactions, and continues to empower public resource transaction management services.

Facilitate transaction data sharing and transaction witnessing

Facilitate transaction data Share

Currently, the data of different trading centers are not interoperable, and the subject information of different trading centers needs to be entered repeatedly. It is difficult to verify the off-site performance provided by the bidders during the bid evaluation process. It is difficult to troubleshoot the same person repeatedly serving as project manager. Issues such as low cost of breach of trust. Establishing a cross-regional subject database based on blockchain can well alleviate the above problems.

The distributed ledger feature based on the blockchain can effectively ensure the real-time or quasi-real-time sharing of data, and can reduce the repeated entry of subject information; the use of blockchain information that cannot be tampered with can ensure the data circulation process on the chain. The authenticity of the bidders in the regional alliance is directly obtained from the on-chain data, making it impossible to hide the fake performance. At the same time, the sharing of bidding behavior data through the blockchain provides a data basis for the development of "joint punishment of dishonest enterprises".

Blockchain-based transaction witness

"Guiding Opinions on Deepening the Integration and Sharing of Public Resource Trading Platforms" ( The State Office Letter [2019] No. 41) pointed out the need to optimize services such as witnessing, venues, information, files, and expert extraction.. However, at present, public resource transaction process witnessing is mainly based on manual on-site witnessing, which has limited witnessing intensity, high occupation of human resources, and limited witnessing effect. Due to its centralized characteristics, the traditional digital witness system is prone to data tampering, and the data is easily damaged or lost during the storage and migration process, which has certain flaws in terms of security and usability.

Utilize the distributed, difficult to tamper, and traceable characteristics of the blockchain to solidify and store the data generated in each transaction link, and accurately record the data generated through time stamp technology, summary algorithm, and electronic signature technology. Time, content, data source. According to the technical characteristics of the blockchain, simple structured data can be directly saved on the blockchain. For unstructured layout files, videos, audio and other large files, the summary information and original files can be saved through the blockchain. Save via a distributed file storage service. When there are disputes or problems in a transaction, the blockchain can provide a set of credible transaction process data and clarify the responsibilities of all parties involved in the transaction. Achieve the goals of risk prevention and control in all aspects, traceability of the entire process, and improvement of all-round services.

Promote the rationalization of electronic guarantee rates

Promote financial services and corporate financing for bidding companies

Promote the rationalization of electronic guarantee rates

At present, electronic bidding deposit guarantee letters have certain applications in the field of bidding, solving the problem of bidding deposit funds for bidding companies. Occupancy issues. However, because financial institutions currently do not have reliable historical bidding behavior data of bidders, they are unable to judge the default risks of different bidders. As a result, the guarantee services charged to bidders adopt fixed rates, which makes a small number of bids with high default risks The cost of personal guarantee is allocated to most bidders with low default risk, which increases the guarantee rates for most bidders to a certain extent.

At present, it is up to the bidder to choose whether to use an electronic letter of guarantee, and the rate is the main choice basis for the bidder. If the bidder performance records are shared through the blockchain and the performance risks of different bidders are analyzed, it will be Different bidders provide different guarantee rates, which not only reduces the risks of financial institutions, but also reduces the use costs of most bidders and promotes the use of bid guarantees. To a certain extent, it can also encourage bidders to abide by their promises and maintain the order of the bidding market. .

Promote financial services for bidding companies

The bidding behavior of bidders is scattered in various trading centers, and the data is simply aggregated In a centralized information system, there is a risk of data tampering (untrustworthy), and valuable bidder transaction behavior data cannot be gathered and shared safely and reliably. Through blockchain technology, bidders from multiple trading centers are gathered, and historical bidding, winning bids, breach of contract, violations and other behaviors are recorded as goldFinancial institutions provide data support for bidders' credit assessment in subdivided industries.

Solving the financing problems of successful bidders

Traditional corporate loans mainly evaluate the company's solvency: collateral, audit There are requirements for accurate financial statements and sustained profitability, but most small and medium-sized enterprises cannot provide these "proofs" at all. Difficulty and expensive financing have become problems faced by many small and medium-sized enterprises in bidding activities. Using the methods of the past will no longer work. To solve the financing difficulties of small and medium-sized enterprises, we can only rely on new technologies and new tools. With the help of the non-tamperable characteristics of blockchain, primary business data from multiple trading centers are gathered, and big data analysis technology is combined to build a portrait of a credible bidder. On the one hand, it improves the risk control level of financial institutions and taps high-quality bidding companies. On the other hand, it lowers the loan threshold for bidding companies and optimizes the service experience.

Drawing on the supply chain finance model, the bidder is a core enterprise with good credit in government departments, national enterprises and institutions, and the winning contract obtained by the winning bidder as a supplier is considered by financial institutions to be a high-quality asset. Apply for a loan from a financial institution. Under the traditional paper-based model, there is a risk of order and contract fraud and the process is cumbersome. Centralized information systems require operators to have strong authority. The distributed ledger and difficult-to-tamper characteristics of the blockchain will help solve the above problems. The contract signing between the tenderer and the bidder and the subsequent financial service links will be realized on the blockchain, which not only solves the problem of data trustworthiness but also reduces the risk of corruption. The entire system relies on a centralized authority.

Through further analysis, we found that credit sales are currently prevalent among domestic enterprises, and the upstream suppliers of the winning bidder have a large funding gap. The credit of the bidder can only be passed to the winning bidder (the winning contract cannot be split or transferred), and the upstream suppliers Business owners are unable to obtain high-quality loans from financial institutions. If the winning contract is converted into a "pass" on the chain, the "pass" can be split, and the winning bidder holding the "pass" can pay part or all of the voucher to the upstream supplier, making it discountable and financing. The "tokens" on the chain can be split and transferred from first-level suppliers to second-level (and multi-level) suppliers, thereby allowing core enterprise credit to be transferred to multi-level suppliers. The shortage of funds from suppliers due to credit sales has been solved, improving the business environment; through value transfer through the blockchain, the financing cycle has been greatly shortened; the cost of supplier loans has been reduced, which will help reduce the production costs of raw materials or intermediate products, and ultimately Increase bidders' profit margins and indirectly reduce bidders' costs.

Regarding blockchain, we can imagine a decentralized management model and technical processing method.

Let me give you an example. There are five people in your family, and they have never been able to figure out how to arrange work and handle family relationships.

So, you and your family discuss it together and simply use voting to solve the problem.

Then this way of voting to solve problems can be called the most elementary blockchain.

Decentralization solves problems.

What application scenarios can blockchain have?

In fact, many of our families and many organizations use blockchain management forms every day

However, this kind of blockchain application for organizational relationships cannot produce Economic Value.

What are the economic applications of blockchain?

The first type is used for tax deposit certificates, bank transfers, etc.

Make full use of the traceability function of the blockchain so that all records can be retrieved and queried at any time

The second type is applied to enterprise operation and management

Enterprises using blockchain management can better solve the problems of enterprise development and allow enterprises to Able to develop faster and make more money.

Summary: The application scenarios of blockchain include taxation, bank transfers, etc., and can also be applied to business operations.

The characteristics of blockchain are distributed accounting and decentralization, but the ultimate goal is to make people get along more equally. Technology is meaningful only when it serves human values, and technology that meets human value needs will develop. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.

Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.

In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.

At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.

Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.

The most popular application industry at present is the financial industry.

An application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to fully trace the origin of some of the products they sell. Consumers can trace the origin of the purchased products. There are also many blockchain applications in the digital advertising industry. Since traffic fraud in digital advertising causes losses of tens of billions of dollars every year, there are already blockchain application projects based on digital advertising, such as DCAD, which is based on blockchain. Digital advertising applications of chain technology,It mainly solves the problem of traffic fraud

In the future, as the application of blockchain technology becomes increasingly mature, it will be applied in many industries and create a new ecological model based on technological trust

Blockchain What is a chain?

If we explain the blockchain in non-technical terms, the blockchain is a place where data is stored. However, the data stored in the blockchain is safe and reliable and does not need to be managed by anyone. Therefore, the data explosion on the Internet has In a place where information is exploding, having such a place would be like a magical treasure land.

What can the blockchain do?

If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:

Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.

If there are any deficiencies, you are welcome to comment and correct me.

In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.

The two parties involved in the transaction do not need to know who the other party is, nor do they need a third party for trust endorsement. They only need to trust a common algorithm to establish mutual trust and conduct direct transactions.

Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire transaction network has changed from a star structure to a point-to-point P2P structure.

In the future, blockchain will be used in many fields and will have a great impact on human life. . It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.

1. Cloud storage

This is the statistics of current cloud storage on the Internet. In terms of volume, Google has the largest volume, which is 8,000PB. So what if we share the idle data on the Internet?

Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15.72864 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.

2. Medical aspects

Using blockchain technology to save personal medical records also retains personal medical historical data. You can directly call the history when seeing a doctor or planning your own health in the future. data. These data are highly private, and the use of blockchain technology also helps protect patient privacy.

⑶ 8 key points in the current development of big data

Author | Zhang Jianfeng

The author has been working for 11 years since 2008. It’s been over a year now, and I have been dealing with data all the way. I have developed the core of the underlying big data framework (Hadoop, Pig, Tez, Spark, Livy), and also developed upper-level big data applications (writing MapRece Job for ETL, using Hive is used for Ad hocquery, Tableau is used for data visualization, and R is used for data analysis). Today I would like to take this opportunity to talk to you about the current situation and future of big data as I understand it.

First, let’s talk about what big data is. The concept of big data has been around for many years (more than 10 years), but there has never been an accurate definition (and perhaps it is not needed). Data engineers (DataEngineer) will understand big data more from a technical and system perspective, while data analysts (Data Analyst) will understand big data from a product perspective, so data engineers (Data Engineer) and There are definitely differences in the understanding of big data by data analysts. What I understand about big data is this. Big data is not a single technology or product, it is all comprehensive disciplines related to data. When I look at big data, I look at it from two dimensions, one is the dimension of data flow (the horizontal axis of the figure below), and the other is the dimension of the technology stack (the vertical axis of the figure below).

Actually, I don’t like to talk about “big data” openly and silently. I prefer to say “data”. Because the essence of big data lies in "data", not "big". Since the media has been focusing on promoting the "bigness" of big data, sometimes we often suddenly realize that the essence of big data is "data" rather than "big". "Big" is just the appearance you see, and the essence is the data itself.

After we clarify the meaning of big data, let’s talk about the current position of big data. From a historical development perspective, every new technology will go through the following technology maturity curve.

When a new technology first comes out, people will be very optimistic. They often think that this technology will bring huge changes to mankind, and have excessive expectations for this. Therefore, this technology initially It will be sought after by everyone very quickly, and then reach a peak, and then people begin to realize that this new technology is not as revolutionary as originally expected.sex, then will be too pessimistic, and then go through a bubble phase. After a certain period of silence, people began to return to rationality, face up to the value of this technology, and then began to apply this technology correctly. From then on, this technology began to move forward steadily. (As an aside, when I looked at this picture, the author also thought of a curve chart of a man’s views on marriage. You can make up your own mind).

1. From the perspective of the history of big data, big data has gone through two important stages.

The two important stages refer to the peak of excessive expectations and the trough of bubbles. Expect. It is now in a stage of steady forward development. We can confirm this from the big data curve on googletrend. Big data began to come into people’s vision around 2009, reached its peak around 2015, and then slowly moved towards the downward channel (of course, this curve will not completely fit the technology maturity curve above. For example, the technology curve is at A descending channel is likely to increase search volume discussing this technology).

Next I would like to talk about some of my judgments on future trends in the field of big data.

2. The scale of data will continue to expand, and big data will continue to shine

As mentioned earlier, big data has passed the peak of excessive expectations and the bottom of bubbles. Trough period, now moving forward steadily. There are two main reasons for this judgment:

The scale of upstream data will continue to grow, especially due to the development and maturity of IOT technology and the rollout of 5G technology in the future. In the foreseeable future, the scale of data will continue to grow rapidly, which is the basic driving force that can drive the continued and stable development of big data. There is still a lot of room for development in the downstream data industry, and there is still a lot of data value that we have not yet explored.

Although artificial intelligence and blockchain have taken away the spotlight of big data, maybe big data will not be the protagonist in the future, but big data is definitely not a side job. Big data will still play an important and basic role. It can be said that as long as there is data, big data will never become obsolete. I think that within most people’s lifetimes, we will witness the continued upward development of big data.

3. The real-time demand for data will become more prominent

The biggest challenge encountered by big data before was the large scale of data (so everyone would call it "big data"). After After years of efforts and practice in the industry, the problem of large scale has basically been solved. In the next few years, the bigger challenge will be speed, that is, real-time. The real-time nature of big data does not refer to the real-time nature of simply transmitting data or processing data, but real-time from end to end. If any step is slow, it will affect the real-time nature of the entire big data system. Therefore, the real-time nature of big data includes the following aspects:

Quick acquisition and transmission of data Fast calculation and processing of data Real-time visualization of data Online machine learning, real-time update of machine learning models

PurposeStream processing computing engines represented by Kafka and Flink have provided solid underlying technical support for real-time computing. It is believed that more excellent products will emerge in the future in terms of real-time visual data and online machine learning. When the real-time nature of big data is enhanced, more valuable data will be generated at the data consumer end, thus forming a more efficient data closed loop and promoting the healthy development of the entire data flow.

4. The migration of big data infrastructure to the cloud is unstoppable

At present, the migration of IT infrastructure to the cloud is no longer an issue that everyone needs to debate. This is the general trend. Of course, the cloud I am talking about here does not only refer to public cloud, but also includes private cloud and hybrid cloud. Because each enterprise has different business attributes and different requirements for data security, it is impossible to deploy all big data facilities on the public cloud, but migrating to the cloud is a destined choice in the future. Currently, all major cloud vendors provide a variety of big data products to meet various user needs, including platform-based (PAAS) EMR, service-based (SAAS) data visualization products, and so on. The cloudification of big data infrastructure also has a corresponding impact on the production of big data technologies and products. Frameworks and products in the big data field will be more Cloud Native.

Separation of computing and storage. We know that each public cloud has its own corresponding distributed storage, such as AWS's S3. S3 can replace HDFS as we know it in some situations, and the cost is lower. The physical storage of S3 is not on EC2. For EC2, S3 is remote storage. So if you are doing big data development and application on AWS, and your data is on S3, then you will naturally use the separation of computing and storage. Embracing containers and integrating with Kubernate is the general trend. We know that Kuberneate is basically the standard for container resource scheduling in cloud environments. More elastic. Tighter integration with other products and services on the cloud.

5. Full-link big data products

Full-link refers to providing end-to-end full-link solutions, rather than simply stacking some big data product components. The main problem that big data products represented by Hadoop have always been criticized is that the threshold for user use is too high and the cost of secondary development is too high. Full link is to solve this problem. What users need is not Hadoop, Spark, Flink and other technologies, but products based on these technologies that can solve business problems. Cloudera's plan from Edge to AI is a solution that I agree with more. The value of big data is not the data itself, but the information and knowledge hidden behind the data that affects the business. Below is a classic excerpt from wikipediaDiagram of data pyramid.

Big data technology is to continuously process and refine the most primitive data. With each level of the pyramid, the corresponding amount of data will be smaller, and the impact on the business will be greater and faster. To ultimately extract wisdom (Wisdom) from data (Data), the data has to go through a very long data flow link. Without a complete system to ensure the efficient operation of the entire link, it is difficult to ensure that the final extraction from data is achieved. To produce something of value, full-link big data products are another big trend in the future.

6. The transfer of big data technology to downstream data consumption and applications

The above mentioned the full-link development trend of big data, so the current long data link What is the situation and what will be the trend in the future?

My judgment is that in the future, the innovation and development of big data technology will shift more to the downstream data consumption and application end. In the past ten years, the development of big data was mainly focused on the underlying framework, such as Hadoop, which initially led the big data trend, and later the computing engine leaders Spark, Flink, message middleware Kafka, resource scheduler Kubernetes, etc., each detail A series of excellent products have emerged in various fields. In general, in terms of the underlying technology framework, the field of big data has basically laid the foundation. The next thing to do is how to use these technologies to provide enterprises with products with the best user experience to solve users' actual business problems. In other words, the focus of big data in the future will move from the bottom to the top. Previous big data innovations were more focused on IAAS and PAAS. In the future, you will see more SAAS-type big data products and innovations. From the recent acquisition cases of some foreign manufacturers, we can get some clues. 1. On June 7, 2019, Google announced that it had acquired the data analysis company Looker for US$2.6 billion and merged the company into Google Cloud. 2. On June 10, 2019, Salesforce announced the acquisition of Tableau in an all-stock transaction of US$15.7 billion, aiming to consolidate work on data visualization and other tools that help enterprises interpret the massive data they use and accumulate. 3. In early September 2019, Cloudera announced the acquisition of Arcadia Data. Arcadia Data is a cloud-native AI-powered real-time analytics vendor for business intelligence. Big data products for end users will be the focus of big data competition in the future. I believe that future innovations in the field of big data will also come from this. There is a high probability that there will be at least one more company like Looker in the next five years, but It is difficult to create another computing engine similar to Spark.

7. Centralization of underlying technology and full bloom of upper-level applications

LearningAnyone who has experienced big data will lament that there are so many things in the field of big data, especially the underlying technology, and it feels like it is impossible to learn. After years of fighting and competition, many excellent products have stood out, and many products are slowly dying out. For example, the Spark engine in the field of batch processing has basically become the leader in the field of batch processing. Except for some old systems, it is basically impossible to develop new MapRece applications for traditional MapRece. Flink has basically become the only choice in the field of low-latency stream processing, and the original Storm system has begun to slowly withdraw from the stage of history. Similarly, Kafka also basically occupies a monopoly in the field of message middleware. In the future, there will no longer be so many new technologies and frameworks in the underlying big data ecosystem, and each subdivision will survive the fittest, become more mature, and become more centralized. In the future, greater innovation will come more from upper-layer applications or full-link integration. There will be more innovation and development in the upper-layer applications of big data in the future, such as BI products based on big data, AI products, etc., big data applications in certain vertical fields, etc. I believe that in the future we will See more innovation and development in this area.

8. Open source and closed source go hand in hand

The field of big data is not only open source products that everyone is familiar with such as Hadoop, Spark, Flink, etc., there are also many excellent closed source products, such as Redshift on AWS, Alibaba’s MaxCompute, etc. Although these products are not as popular with developers as open source products, they are very popular with many non-Internet companies. Because for an enterprise, there are many factors to consider when deciding which big data product to adopt, and whether it is open source or not is not the only criterion. Whether the product is stable, whether it is supported by commercial companies, whether it is secure enough, whether it can be integrated with existing systems, etc. are often things that some companies need to consider more, and closed source products often have advantages in such enterprise-level product features.

In recent years, open source products have been greatly affected by the public cloud. Public clouds can enjoy the results of open source for free and have taken away a lot of market share from commercial companies behind open source products. Therefore, recently many commercial companies behind open source products have Companies began to change their strategies, and some even revised their licenses. However, I think public cloud vendors will not kill the commercial companies behind those open source products. Otherwise, they will kill the goose that lays the eggs. Killing the commercial companies behind the open source products is actually killing the biggest technological innovator of the open source products, which is killing the open source products themselves. . I believe that the open source community and public cloud vendors will eventually reach a balance. Open source will still be a mainstream and the main force in innovation. Some excellent closed source products will also occupy a certain market space.

Finally, I would like to summarize the key points of this article again:

1. At present, big data has passed the peak period of popularity and the trough period of bubble.is in a stage of steady forward development. 2. The scale of data will continue to expand, and big data will continue to flourish. 3. The demand for real-time data will become more prominent. 4. The migration of big data infrastructure to the cloud is unstoppable. 5. Big data products will be fully linked. 6. Big data technology will move downstream. Data consumption and application-side transfer 7. Centralization of underlying technology and full bloom of upper-level applications 8. Open source and closed source go hand in hand

⑷ You have to know the operating principles and development of blockchain!

1. Why is there innovation in blockchain?
The starting point of the first generation of the Internet is the TCP/IP protocol, which implements a unified format for peer-to-peer transmission of information by all nodes on the network. Open code. However, the impact of such an uncomplicated innovation on mankind is epoch-making. It has programmed, agreed, and enforced the basic values ​​required by a unified global market: "freedom, equality, and fraternity." Then the STMP email protocol, HTTP domain name protocol, etc. were derived, achieving low-cost and high-efficiency global information transmission in a decentralized manner. As Alibaba Vice President Gao Hongbing said:
"The Internet is to eliminate the (information) supply chain that has very low value and high cost - it is open, interconnected, peer-to-peer, globalized, and decentralized."
We know: The essence of the market is also decentralized. It automatically executes the decentralized agreement of "equivalent exchange". Just as Nobel Prize winner Ronald Coase summed up: "The market economy is based on two On the basis of deep cognition: admitting ignorance and tolerating uncertainty." Adam Smith also described the market as: "the invisible hand"! Therefore, the market must require the low-cost flow of information decentralization, and the Internet has adapted to the global Under the general climate formed by the unified market, it turned out to be.
However, the first generation of Internet decentralized solved the problem of low-cost and efficient transmission of information, but it did not solve the problem of credit of information. Therefore, what the second-generation Internet must break through is: how to establish global credit in a decentralized manner so that value transfer can be carried out at low cost and with high efficiency.
So what are the problems with the original centralized credit system? As we all know: centralized credit, such as the legal currencies of various countries, has different credit values, and the clearing systems are also incompatible, which adds a lot of cost to global trade. The current global credit system centered on the US dollar has a "Triffin Paradox" in its mechanism (the essence is that a country's legal currency cannot simultaneously resolve the conflict between its own economic interests and global economic needs). Therefore, in 2009, the Governor of the Central Bank of China, Zhou Ogawa called for the creation of a super-sovereign storage currency. In the same year, Satoshi Nakamoto disclosed the first-generation blockchain source code-"Bitcoin" online.
2. How does the blockchain system operate?
First of all, Satoshi Nakamoto knew very well that establishing a credit system for payment must solve the problem of preventing "duplicate payments", that is, no counterfeit currency can be created. The centralized credit system relies on state machinery to prevent counterfeit currency. What about "Bitcoin"? Satoshi Nakamoto's great innovation is to "timestamp" every transaction.There is a block (block: equivalent to a network account book) every ten minutes, and all network transactions for these ten minutes are correctly timestamped. The question is who will cover it? Satoshi Nakamoto did not assume that everyone on the Internet is Lei Feng. He agreed with Adam Smith: people in the market are greedy. He asked the so-called "miners" to compete for the accounting rights of these ten-minute blocks. The rules of the competition were to correctly record the accounting and at the same time solve the SHA256 problem. Who can prove that their computer has the fastest computing power (the so-called PROOF OF WORK mechanism), he can compete for the legal accounting rights of these ten-minute blocks and get a reward of twenty-five bitcoins. This is the so-called "mining" process. It is actually a decentralized credit process that establishes a network-wide ledger - the blockchain. Therefore, the more essential function of miners is "bookkeepers"!
Satoshi Nakamoto is here In its Bitcoin white paper, the process of establishing this credit system is described in detail:
Step 1: In order for the entire network to recognize it as valid, each transaction must be broadcast to each node (node: that is, the miner);
The second step: Each miner node must correctly timestamp each transaction in these ten minutes and record it in that block;
The third step: Each miner node must Compete for the legal accounting rights of this ten-minute block by solving the SHA256 puzzle, and strive to get a reward of twenty-five bitcoins (fifty bitcoins every ten minutes for the first four years, decreasing by half every four years);< br>Step 4: If a miner node solves the SHA256 puzzle of these ten minutes, it will publish all the timestamped transactions recorded in its ten-minute blocks to the entire network, and they will be checked by other miner nodes in the entire network;< br>Step 5: Other miner nodes in the entire network check the correctness of the block accounting (because they are also stamping the accounting at the same time, but they have not competed for the legal block accounting rights, so there is no reward), there is no error Finally, they will compete for the next block after the legal block, thus forming a single chain of legal accounting blocks, which is the general ledger of the Bitcoin payment system - the blockchain.
Generally speaking, each transaction must undergo six block confirmations, that is, six ten-minute accounting, before it can finally be recognized as a legal transaction on the blockchain. The following is the accounting format of Bitcoin:
So the so-called "Bitcoin" is such a billing system: it includes the owner electronically signing with the private key and paying to the next owner, and then the entire network's "miners" "Time stamp the account and form a blockchain.
3. What are the innovations in Bitcoin’s blockchain finance?
Similar to gold, trying to establish decentralized credit on the global Internet may allow value to flow across the entire network at high speed and at low rates (currently each transfer The transfer rate is one ten thousandth);
The total amount of currency is agreed upon by the cryptographic protocol;
Compared to gold, digital currency is infinitely divisible;
The value of currency can be based on a large number of P2P transactions ;
Full transparency in financial management (every transaction can be traced on the blockchain).
Bitcoin's blockchain accounts for the entire network, and has a market value of US$10 billion, the highest on the global Internet. Therefore, Wu Xiaoling, dean of Tsinghua PBC School of Finance, pointed out: The blockchain experiment established distributed credit, which is an upgraded version of Internet TCP/IP, upgrading from information transmission to value transmission;
4. Bitcoin’s blocks What are the inherent flaws of the chain system?
Bitcoin’s blockchain system has had successes since it was open sourced on the Internet in 2009, but it also shows some inherent flaws that are difficult to overcome:
The total amount cannot be adjusted at any time As the market situation changes, it will inevitably rise and fall sharply;
Mining is high-carbon. Only less than 1% of miners can compete for the accounting rights of blocks of less than ten minutes, and more than 99% of other miners participating in the competition have the computing power. Waste;
The annual inflation of about 10% has greatly increased the cost of the Bitcoin financial ecology, and even threatened her survival;
As a decentralized self-organizing DAC system, the operating costs of the accounting and issuance functions are too high high.
As a global payment system, its efficiency is far from meeting the actual requirements of global trade. The Bitcoin network currently confirms a maximum of 7 transactions per second. In comparison, Visa's network system can process 10,000 transactions per second at the fastest, and Alipay's record is 80,000 transactions per second on Singles' Day in 2014!
5. Block The development of chain technology 2.0:
As the 2.0 upgrade and development of blockchain, it first focuses on solving the high-carbon mining of Bitcoin accounting:
When we discuss how to overcome the high carbon of Bitcoin mining and accounting Professor Liu Taoxiong from the Tsinghua Institute of Economics pointed out that mining competition relies on computing power. In the end, only one company competes for the legal accounting rights, and the other 99% of the miner nodes are mined for nothing, which is a waste of resources. It is obviously unreasonable. If The whole network transparently knows the legal accounting rights of the next block, and it is randomly generated in the entire network, which eliminates the high carbon cost of competitive accounting! After hearing this, we all praised Professor Liu for his brilliant idea, because the second generation is now more successful. Coin NXT has this mechanism. Their white paper is called "Transparent Forging". However, the probability of the accounting rights going to someone is directly proportional to the NXT token holdings in each miner node wallet. This is called the proof of equity mechanism ( PROOF OF STOCK). Of course, this also triggered a debate about the unfairness of NXT’s distribution of tokens to early investment developers!
RIPPLE is a semi-decentralized blockchain solution that uses “trusted gateways” to conduct block operations. The credibility of chain accounting is based on the consensus ledger protocol that these gateways will not do evil at the same time.
The most ambitious attempt is Ethereum, which combines blockchain technology with Turing completeness, hoping to develop a basic platform that can support the construction of various blockchain systems in the future. The development of various credit currencies, digital assets, smart protocols and even financial derivatives. Its system design is the unified blockchain record of the ETHERUM platformThe account is shared by all developers, and perhaps their official version will be released in the near future.
6. Possible applications of blockchain innovation in other fields:
Now, blockchain’s attempts to establish decentralized credit are no longer limited to the financial world, but have attracted attention from all fields of society, especially in At present, some of China's central credit institutions, such as the "Red Cross", are in a "collapse" situation. Blockchain can provide a new way of thinking and technical options for social management. The following are some new developments and related discussions we have learned about:
The combination of blockchain and the Internet of Things unifies digital assets and atomic assets, smooths the difference between consumer assets and cash assets, expands public credit, and accelerates value circulation; (IBM-Samsung)
Built on the blockchain Intellectual property protection system, accounting for the use of intellectual property across the entire network, and establishing a global advertising market;
Whether blockchain can provide technical support for the issuance of protocol-based cryptographic currencies by emerging economies along the Belt and Road;
Block Chain + cloud computing can develop into a decentralized self-media and community system;
Blockchain can build a decentralized equity crowdfunding system, allowing innovative projects to enter the circulation field in advance;
Blockchain can develop Develop a fully transparent financial management system;
Blockchain supports the establishment of a global decentralized corporate organization.
In short, in this era when credit has become a scarce resource, the technological innovation of blockchain, as a distributed credit model, provides new opportunities for finance, social management, talent evaluation and decentralized organization construction in the global market. All provide a broad development prospect.

⑸ What are the development trends of China’s blockchain in 2021

Looking forward to 2021, the top-level design of my country’s blockchain will be further improved, and application standards for various industries will be gradually established. The development direction has shifted from technology leadership to market penetration; blockchain integration applications have begun to be implemented in many fields such as finance, supply chain, and government affairs, 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.
Yibaoquan has been committed to the research and development and application independent innovation of blockchain since 2014. It is a blockchain electronics company that has maturely used blockchain technology to solidify and store electronic data and has been recognized by judicial authorities. Data storage and security agency.

Industry overview

1. Definition

In a narrow sense, blockchain is a chronological A chained data structure that combines data blocks in a sequential manner and is cryptographically guaranteed to be an untamperable and unforgeable distributed ledger.

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 solutions based on blockchain technology.Applications provide productized services such as smart contracts, information security, and data services based on underlying technologies to improve the convenience and scalability of developers developing 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 Pushing the blockchain into the 2.0 era; at the end of 2017, the popularity of stablecoins and the launch of MakerDAO pushed 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, and various countries regulated Departments have spoken out one after another, showing the huge potential of blockchain technology in reshaping global financial infrastructure. 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.

OKCurrent status of industry development

1. The market size will grow by more than 90% in 2020

From 2016 to 2018, large IT Internet companies have deployed blockchain, start-ups have entered a blowout mode, and the industry The scale continues to expand. According to IDC data, China's blockchain industry has experienced changes from a market size of US$85 million in 2017 to an industry scale of US$561 million in 2020.

2. The number of related companies is growing rapidly

In terms of the number of companies, in 2020H1, my country provided blockchain professional technical support, products, solutions and other services, and had input or output The number of new blockchain companies reached 303, a year-on-year increase of 274.07% nationwide. As of the end of 2020, the number of blockchain-related companies in my country reached 64,062, a year-on-year increase of 52.88%.

3. Blockchain finance is the largest downstream application market

According to the disclosure of the "China Blockchain Development White Paper (2020)", as the implementation of blockchain applications accelerates, "Blockchain+" business has become the focus of development for Internet backbone enterprises to enter the blockchain industry. In addition to financial business, it actively deploys the Internet, traceability, supply chain & logistics, digital assets, government affairs and public services, intellectual property, and law. , medical and other fields of application. Among them, finance is the most explored field in the application scenarios of blockchain technology, with specific projects implemented in subdivided fields such as supply chain finance, trade finance, payment and settlement, and fund management.

4. The number of blockchain tenders is increasing year by year

From a year perspective, from 2016 to 2020, the number of government tenders for blockchain-related projects has been growing exponentially. , on the one hand, it benefits from the increasingly prominent application value of blockchain technology, and on the other hand, it also reflects the government’s increased demand for and emphasis on blockchain.

Industry competition status

1. Regional competition: Beijing and Guangdong have the most blockchain technology research and development-related companies

In terms of company distribution, as of the first half of 2021 , the distribution of enterprises is obviously tiered. Among them, Beijing and Guangdong rank in the first echelon with 348 and 341 blockchain development-related companies respectively, and the number of companies in Jiangsu, Shanghai, and Zhejiang reaches 164, 127, and 81 respectively.

As an important carrier for the development of blockchain industrial clusters, local governments are accelerating the construction of blockchain industrial parks. Judging from the location distribution of industrial parks, there are a large number of blockchain industrial parks in cities such as Beijing, Shanghai, Hangzhou, Guangzhou, Chongqing, Qingdao, and Changsha, forming a Bohai Rim agglomeration effect dominated by Beijing and Shandong, with Zhejiang and Shanghai , the agglomeration effect of the Yangtze River Delta dominated by Jiangsu, the agglomeration effect of the Pearl River Delta dominated by Guangdong, and the agglomeration effect of Hunan, Guizhou, and Chongqing dominated by Chongqing and Hunan. Combined with the positioning and development of the industrial park, it is based on the premise of serving enterprises to create a blockchain innovation platform and industrial highland. This positioning also provides the basis for the aggregation effect of enterprises.

2. Enterprise competition: Alibaba’s blockchain is the strongest

In March 2021, at the China Mobile Communications Federation’s Blockchain Professional Committee and the China Science and Technology System Reform Research Association’s Digital Economic Development Under the guidance of the research team and the Organizing Committee of China’s Top 100 Blockchain Enterprises List, Chain Tower Think Tank screened and evaluated thousands of projects and enterprise lists, and finally released the 2020 China’s Top 100 Blockchain Enterprises List.

In the context of the outbreak of the epidemic in 2020, the 2020 Blockchain Top 100 List has adjusted the dimensions of enterprise inspection to a certain extent to highlight the performance of outstanding blockchain companies in 2020. It is divided into five main dimensions, namely commercial operation weight accounting for 25%, technology research and development weight accounting for 20%, product application weight accounting for 30%, team composition weight accounting for 15% and marketing promotion accounting for 10%.

Industry development prospects and trend predictions

1. It is still in the introduction period

Currently, my country’s blockchain industry is in the introduction period, and the industry is showing Two main characteristics: First, large industry companies are actively applying blockchain technology to improve their own businesses, but they are still mainly trying, and the main application scenarios are also non-core businesses in the industry. For example, enterprises such as Ping An of China, China UnionPay, and Ant Financial are limited to non-core businesses in their exploration of blockchain applications; secondly, the business development of enterprises focusing on blockchain technology services is mostly in the initial stage, and their product technology systems and The business model is not mature enough, and the demand side’s understanding of blockchain needs to be improved. Blockchain has already formed some application cases in scenarios such as judicial certificate storage, government affairs management, people's livelihood services, food traceability, supply chain management, etc., but it still needs to be further optimized and improved.

The above data refers to the "China Blockchain Industry Market Foresight and Investment Strategic Planning Analysis Report" by the Qianzhan Industry Research Institute.
