A. How is the development of my country's blockchain industry now

my country's blockchain industry is still in its infancy, but with the continuous support of national policies, industry technology With the continuous progress and the increasing demand in downstream application fields, my country's blockchain industry is expected to continue to maintain rapid growth. IDC predicts that the overall expenditure scale of China's blockchain market will reach US$2.28 billion in 2024, with a compound annual growth rate of up to 51%.

Data released by CCID shows that since 2016, large IT Internet companies have deployed blockchain, start-ups have entered a blowout mode, the frequency and amount of investment and financing have increased dramatically, and the scale of the industry has continued to expand. As of December 2019, my country has a total of 1,006 blockchain companies that provide blockchain professional technical support, products, solutions and other services, and have input or output.

In October 2019, blockchain officially rose to the level of national strategy In April 2020, the National Development and Reform Commission included "blockchain" in the scope of new infrastructure for the first time, clarifying that it belongs to the new technology infrastructure of the information infrastructure part of the new infrastructure. This has brought opportunities to the blockchain market, which is facing severe challenges under the impact of the epidemic, and has also given blockchain further momentum in terms of technological development and industry applications.

B. What is the development status of my country’s blockchain technology?

Domestic blockchain technology has now been conceptualized from the very beginning and has now been applied to actual business scenarios. Among them, for example, Vonetracer traceability system of Wanglian Technology, their blockchain traceability technology has been applied to actual agricultural products.

C. After experiencing explosions and disillusionment, can blockchain games still be reborn?

Blockchain games can still be reborn. After all, everyone’s demand for them now is It is very big, and this area has been studied in depth. It has not been abandoned, and there is still hope for the future.

Many blockchain practitioners have high hopes for blockchain games and believe that it is one of the best means to promote blockchain technology. However, due to limitations of technology, funds, user preferences and other reasons, most of the first batch of blockchain games have been reduced to drumming, flower-passing scams and fund disk carriers. A year later, more and more practitioners are trying to change this situation, but they still face many problems and challenges.

After experiencing explosions, disillusionment and rebirth, the future of blockchain games is still full of hope. So blockchain links will usher in a new beginning.

D. After more than ten years, the blockchain is still tepid. Has it failed?

Almost everyone, even those who are skeptical about tokens, All have positive views on blockchain technology because it has the potential to change the world. However,It has been 10 years since the advent of blockchain technology, and we still have not really used it. Some people say that Bitcoin is built on blockchain technology, so the main use of blockchain is as a payment system, or as it develops, as a store of value.

Other uses of blockchain include, for example, as a distributed trading platform, as a new currency, smart contracts, distributed storage, authenticity verification, and immutable distributed ledgers. However, although these have been tried, there are no real applications.

Smart contracts are an interesting phenomenon. Founder Vitalik Buterin aims to create a global computing network that can completely eliminate the need for a centralized third party. This is certainly great in the modern world. However, smart contracts still have a long way to go. The DAO fiasco proved that smart contracts can still be fooled, or should we say, smart contracts are sometimes too smart for their own good.

However, as IC0s continue to use smart contracts as the basis of their business, it proves that blockchain still has hope in this area. Whether it can play a major role in these areas remains to be seen.

The list goes on and on. Without a doubt, it can be deduced that blockchain technology can be integrated into almost all sectors of modern life (including those mentioned above). However, it has been nearly 10 years since the birth of blockchain technology, and no field has yet used blockchain technology to replace the original technology. The ideas are great, but the execution of this technology is simply too slow.

E. Is blockchain the trend in the next ten years?

Blockchain is the biggest trend in the next ten years!
If you look at the problem with the thinking of 30 years ago, you will think that others are crazy, but in fact you are behind the times.
The concept of blockchain can be traced back to the end of 2008. A mysterious person named "Satoshi Nakamoto" published a paper "Bitcoin: A Peer-to-Peer Electronic Cash System" in the forum. , first proposed the concept of blockchain.
On January 3, 2009, the first block of the blockchain was born. This block is called the "original block".
Almost with the birth of blockchain technology, Bitcoin became the first thing to play its role. In the following years, Bitcoin gradually became popular around the world. In 2017, its crazy market made blockchain technology a Everyone knows.
The idea of ​​blockchain first appeared in the famous Bitcoin open source project. During the birth and development process of the Bitcoin project, it drew on technical achievements from many fields such as digital currency, cryptography, game theory, distributed systems, cybernetics, etc. It can be said that it draws on the strengths of many experts as its core support structure The blockchain technology is an eye-catching innovation.
Blockchain is a distributed data system participated by different nodes.The database system is an open ledger system (ledger).
Three major characteristics of blockchain
Compared with traditional centralized solutions, blockchain technology mainly has the following three characteristics:
The core idea of ​​blockchain is decentralization< br />In the blockchain system, the rights and obligations between any nodes are equal, and all nodes have the ability to vote with computing power, thus ensuring that the recognized result is the result recognized by more than half of the nodes. Even if it suffers a severe hacker attack, as long as the number of nodes controlled by the hacker does not exceed half of the total number of global nodes, the system will still be able to operate normally and the data will not be tampered with.
The biggest disruption of blockchain is the establishment of credit
Theoretically, blockchain technology can make WeChat Pay and Alipay no longer valuable. "The Economist" gave a vivid metaphor to the blockchain: simply put, it is "a machine that creates trust." Blockchain allows people to collaborate without trusting each other and without a neutral central authority. Combating counterfeit currency and financial fraud will no longer be needed in the future.
The collective maintenance of blockchain can reduce costs
In a centralized network system, the maintenance and operation of the system rely on the operation, maintenance and operation of platforms such as data centers, and costs cannot be omitted. Anyone can participate in the nodes of the blockchain. While participating in the recording, each node also verifies the correctness of the recording results of other nodes, which improves maintenance efficiency and reduces costs.
In one sentence, blockchain touches money, trust and power, which are the fundamental foundations on which human beings survive.
Its development has gone through 3 stages
1. Incubation period: 2009-2012, the economic form is dominated by Bitcoin and its industrial ecology.
2. Embryonic period: The period is from 2012 to 2015. Blockchain entered the public eye with Bitcoin, new wallet payment and remittance companies appeared, and the blockchain economy spread to the financial field. The underlying technology of blockchain continues to innovate. Blockchain technology is divorced from the Bitcoin system.
3. Development period: In 2016, industry applications began to be explored, and a large number of blockchain startups emerged. The popularity of ICO in 2017 brought unprecedented attention to blockchain.
The "Blockchain 2.0 Era" is coming
The application service layer is the driving force for the sustainable development of the blockchain, and is divided into three stages of application: 1.0, 2.0, and 3.0.
Programmable Currency: Blockchain 1.0 Application
Programmable Currency is a digital currency represented by Bitcoin, but it is not the legal currency of any country or region, and no government authority provides it with guarantee.
Programmable Finance: Blockchain 2.0 Applications
Blockchain 2.0 applications have added the concept of "smart contracts" (using program algorithms to replace humans to execute contracts). This allows the blockchain to expand from the initial currency system toRegistration and transfer of equity, debt and property rights, trading and execution of securities and financial contracts, and even financial fields such as gambling and anti-counterfeiting.
Programmable Society: Blockchain 3.0 Application
Blockchain is the core of the Internet of Value and can confirm, measure and store property rights for every information and byte representing value in the Internet. It can not only record transactions in the financial industry, but can record almost anything of value that can be expressed in the form of code. Its application can be extended to any field with demand, and then to the entire society.
Currently, blockchain applications have begun to surpass Bitcoin (Blockchain 1.0), enter the Blockchain 1.5 era, and transition to the financial field (Blockchain 2.0).
In the next 3-5 years, blockchain may transcend the financial field and enter the social notarization and intelligent fields (blockchain 3.0), including identity authentication, notarization, arbitration, auditing, domain names, logistics, medical, In areas such as mail, visas, and voting, the scope of application has expanded to the entire society. Blockchain technology may become a bottom-level protocol for the "Internet of Everything."
Currently, blockchain technology has been recognized by the world, and its development has become an inevitable trend. Along with this comes more people’s attention, “In the next 30 years, new technologies will be integrated into all aspects of traditional industries, and human society will be turned upside down. No matter who you are or where you are, all of us will They will all be part of this big change."
This is the current situation. Blockchain has given the post-90s generation an opportunity. But if you want to master blockchain technology without being affected by negative factors, the most important thing is , can only have a clear understanding of it, whether it is a regulator, researcher, speculator, or bystander.
It’s time to invest more of your energy and pay attention to blockchain technology.
The average annual salary of blockchain positions in my country has reached more than 300,000, and the annual salary of some companies has reached more than 1 million. The monthly salary of fresh graduates in the blockchain industry in Beijing, Shanghai and other places has exceeded 20k! The post-90s generation may seize the dividends of the times and become the next Alibaba in the future! If you miss it, you may regret it for ten years.

F. The development of blockchain has been frustrated during the epidemic, and flashy blockchain pilots are falling out of favor

Under the new crown epidemic, blockchain suppliers and advocates are afraid that enterprises will Blockchain implementation setbacks.

The adoption of blockchain is a relatively new area for business leaders. As the economy shrinks and IT budgets shrink, blockchain may be the first project to be axed.

While no sweeping changes have hit blockchain adoption, the landscape of the technology has certainly shifted.

Similar to the trends in data and software, the focus of blockchain implementation in the COVID-19 era has also shifted to areas where technology can provide the greatest value in the shortest time.

Eschewing flashy pilots without clear intent, leaders are targeting interests in areas of higher value, with COVID-19 pressures further deepening the weaknesses of existing blockchain applications.

In the aftermath of the crisis, funding for blockchain pilots has slowed as bosses suspended forward-looking projects and spent funds on more urgent firefighting activities.

According to forecasts released by IDC in June, as global IT budgets shrink, global blockchain spending is expected to reach US$4.3 billion in 2020, a year-on-year increase of 57.7% from US$2.7 billion in 2019. . Despite this growth forecast, it is down 7.7% from IDC's last forecast.

Global blockchain budgets are currently forecast to reach $14.4 billion by 2023, a further reduction from the pre-COVID-19 estimate of nearly $16 billion.

The current actual impact on blockchain adoption has been low. One trend has been a decline in interest among large companies in pilots and proof-of-concepts without clear commercial returns.

When assessing the shift in blockchain adoption post-COVID-19, a crucial context is the instability of the economic environment.

When the first wave of lockdowns hit North America and Europe, almost all blockchain work was initially halted except for networks already in production.

Some large vendors and software integration companies have shifted their focus to enabling remote work, with people almost all working from home.

When considering blockchain implementation, enterprise technology leaders must always be wary of the hype from vendors and technology proponents and think carefully.

According to Gartner data, as of 2019, only 4% of organizations have blockchain projects and are running them on a large scale.

In the current environment, where IT leaders are under pressure to shrink budgets, any blockchain project that does not have a very clear reason for existing risks being shut down.

When companies evaluate the merits of blockchain pilots, clear benefit criteria include:

But for blockchain implementation, as an integral part of the platform, it can improve Supply chain and cost reduction.

Delivering these benefits has proven elusive for most businesses. According to Gartner, even those networks that exist today will need to be replaced as technology evolves to remain competitive, secure and avoid obsolescence.

As enterprises adapt to new operating environments, blockchain offers a way for enterprises to reduce the cost of reliable access to data between partners and reserve non-value-added costs.

To effectively pursue blockchain as part of their digital transformation journey, CIOs need to determine which aspects of their business and operating models can be automated to better serve customers.

Organizations should evaluate which combination of solutions can help achieve this outcome. In this case, blockchain can be connected with artificial intelligence or the Internet of Things. Instead of looking at blockchain as one thing that provides multiple capabilities, try to see the different capabilities of blockchain and try to integrate them into your business needs.

G. What are the employment prospects of blockchain technicians?

The employment prospects are broad. At the current stage, blockchain technology is still in the stage of systematic development and technological application exploration, so related industries Most of the personnel focus on theoretical research and exploration and development of implementation scenarios.

With the vigorous development of Blockchain 2.0 and the proposal of the concept of Blockchain 3.0, Blockchain technology has expanded from the financial field to all aspects of social life, and a large number of enterprise-level applications have begun to use Blockchain technology.

In addition, the market currently lacks comprehensive technical talents who understand computer technology, have relevant algorithm foundations, and can use Ethereum and Hyperledger Fabric applications. For developers, blockchain application development will be a new continent.

1. Block + chain

As the name suggests, blockchain is a combination of blocks in a chain. In this way The database formed in this way is called a blockchain database. Blockchain is a transaction database shared by all nodes in the system. These nodes participate in the blockchain network based on value exchange protocols.

2. Distributed structure

The blockchain builds a distributed structural system based on the open source and decentralized protocol determined by the system, allowing value The exchanged information is sent to the entire network through distributed propagation, and the information data content is determined through distributed accounting, stamped with timestamps to generate block data, and then sent to each node through distributed propagation to achieve distributed storage.

3. Asymmetric encryption algorithm

To put it simply, it allows us to use two passwords respectively in the process of "encryption" and "decryption". Passwords are asymmetric.

4. Script

A script can be understood as a programmable smart contract. With scripts in place, blockchain technology will give the system the opportunity to handle some unforeseen transaction patterns, ensuring that this technology will not become outdated in future applications and increasing the practicality of the technology.
