① HBA public chain: Create a public chain ecosystem covering blockchain + full-scenario applications

Since the development of blockchain technology, people and even the country have gradually paid attention to it. As a new application model based on computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms, the essence of blockchain is a decentralized data storage system that can be updated but cannot be tampered with.

The application of blockchain technology has extended to digital asset transactions, the Internet of Things, commodity traceability, digital culture, digital medicine, network security, medicine and health, etc., promoting social production and life. Major changes in methods and production relations.

The research and development of the HBA public chain began in February 2019. The core team is composed of early overseas blockchain participants and is jointly maintained by multiple decentralized distributed communities around the world. Innovatively proposes the 3R circular economy model (Rece, Renue, Racycle). The token uses the POC+POS mechanism to gradually reward everyone who contributes to the ecology. It will not generate a large number of tokens at no cost like other public chains, and is effective. It has cracked down on industry chaos and ensured fairness for every ecological participant.

HBA has realized a truly decentralized blockchain through a large amount of technology accumulation, developed source code, and established a complete blockchain browser. Users can query the generation of each block and the process of each transaction. It provides a truly fair and open environment in which no one can cheat and everyone can truly become a supervisor of the system.

The ecological application scenarios of the HBA public chain include digital identity, artificial intelligence, supply chain finance, DEFI platform, cross-chain payment, health care, food safety, and education. At present, the development of public chains, blockchain browsers, and decentralized exchanges has been completed. The HBA public chain will be tested on the mainnet in October 2020!

At the same time, in the ecology of the HBA public chain, there is also a group of self-organized evangelists and professional lecturers to serve the HBA member ecology and provide a one-stop service of "incubation, training, and market development" for the HBA ecological community. Serve.

With the characteristics of "fast, convenient and accurate" intelligent technology, it provides people with "one-stop" medical and health service solutions.

IPFS, the Chinese name of the Interstellar File System, is a point-to-point distributed file system. It is a hypermedia transmission protocol based on content addressing, versioning, and point-to-point. Its purpose is to supplement or even replace the The traditional centralized storage HTTP protocol has been used for more than 20 years.

The advantages of IPFS are: efficiency, security, privacy, permanent storage, low cost, faster access, etc.

HBA’s block data is stored using the IPFS decentralized storage structure. All blocks have pointer references to the previous block to ensure that the data is not tampered with. The sha256 function is used to hash the data, the ecc asymmetric encryption algorithm is used for identity authentication, the aes encryption algorithm is used to encrypt the private key, and the Merkle number is used to verify and store transactions.

HBA public chain combines the advantages of blockchain for distributed storage, aiming to improve data security, privacy and users' control over their data. At the same time, users can receive token rewards by participating in providing storage space. .

② In the field of blockchain, what is one of the most mentioned concepts

There are two fields that are The most mentioned ones are finance and logistics.
Logistics is an express delivery industry that involves many business scenarios, making it a useful place for blockchain. Relevant people said that the express logistics industry is very suitable for applying blockchain technology. Call it logistics blockchain. It is worth mentioning that the logistics ecosystem is inherently a community of interests composed of many aspects.

The global trade system has very complicated processes and redundant communication. 80% of the consumer goods used by everyone and 90% of global trade are transported through the sea. In addition to being error-prone, the efficiency is also relatively low. .

But the blockchain solution can very well transform this process. This is very helpful for participants, including manufacturers and customers, to obtain information early, and will also improve the efficiency of the entire process to a large extent.

What benefits does this bring to all parties involved, including manufacturers, shipping companies, customers, etc.? Obtaining information in advance and reducing communication can greatly improve the efficiency of the entire process. In addition, if goods are lost, responsibility can be determined faster and more accurately and the problem can be solved. [Answer]

1. Digital currency

After the rise of electronic finance and e-commerce, the security, convenience and low transaction cost of digital currency are more suitable for network-based Commercial activities on the Internet may soon replace the circulation of currency in the house. In the near future it will also be possible to replace the circulation of physical currency.

Many countries are currently exploring the feasibility of issuing digital currencies, including Sweden and Australia, which are studying plans to develop digital currencies.

2. Payment and settlement

Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment and does not involve intermediate institutions. This is very effective in improving speed and reducing costs at the same time.

Especially in the aspect of cross-border payments, if an Ethernet universal distributed banking financial transaction system is built on the basis of blockchain technology, it will be able to provide users with global cross-border, Real-time payment and clearing services in any currency, cross-border payments will also become more convenient and cheaper. [Answer]

3. Invoices and supply chain financial services

Invoices and supply chain financial services are subject to excessive human intervention, which has led to many violations andand the emergence of operational risks. Since mid-2015, a credit crisis has begun to erupt in the bill business in China. While there is a large amount of liquidity in the bill business, there are also a large number of illegal operations and customer fraud in the related markets. Gradually, the bill business of many commercial banks began to explode.

Because supply chain finance is highly dependent on labor costs, there are many complex links in the business processing process, which not only wastes time but also wastes human and financial resources, and there are manual errors in each link. Chance.

With the help of blockchain technology, current bills do not require specific physical bills or a central system for control and verification, and can directly realize point-to-point value transfer. In addition, the elimination of intermediaries also reduces the involvement of operational factors.

Because of blockchain technology, supply chain finance can also maintain labor costs, improve security and achieve end-to-end transparency. In the future, through blockchain, the financial business of the supply chain can also significantly reduce manual intervention and digitize the current paper-based procedures. [Answer]

These are several concepts often mentioned in blockchain [Answer]

③ What are the development prospects of digital currency? Can it be regarded as a scam?

Due to the continued popularity of Bitcoin, people have begun to pay close attention to this digital currency. However, what attracts more attention is the technical architecture behind Bitcoin - blockchain technology. This technology has been used by many institutions. It is believed that it is likely to be the core technology most likely to trigger the fifth round of technological revolution after steam engines, electricity, information and Internet technology.

Bitcoin may fall, but the long-term direction of digital currencies must be to rise, and it will rise particularly violently. In 2017, the total market value of global digital currencies was only US$647 billion, less than 10% of the global physical gold market value, and accounted for less than 0.01% of the total national stock value. The launch of AAC comes at the right time, and miners know that the earlier they enter, the more tokens they can mine and the more profits they can earn. The birth of Acute Angle Cloud will bring generous returns to its partners.

2017 can be considered the first year of blockchain technology, and 2018 is likely to be the year of the explosion of blockchain technology. Acute Angle Cloud is likely to usher in a new era if it catches the fast train of blockchain technology. With explosive growth, the Acute Angle PC released at CES2018 is likely to become another blockbuster product of the blockchain.

④ See how the world’s top ten stock exchanges play with blockchain

However, the world’s 10 major stock and commodity exchanges have currently expressed interest in blockchain technology. . In this article, we will give you a detailed introduction:
1. Australian Securities Exchange (ASX)
When it comes to blockchain technologyThe ASX is definitely one of the most ambitious companies when it comes to applications, investing more than $10 million in digital asset holdings, a startup in the sector, in January as part of its research and development drive.
At the same time as the investment, the ASX also revealed that it will not only conduct technology trials, but also establish a new post-trade settlement system, which will be developed by Digital Asset through the use of a distributed ledger structure.
However, since January this year, updates on the project’s progress on the ASX may have been overshadowed by controversy. In March, Australian news media began speculating that, although the ASX had reaffirmed its support for the trial, the blockchain project might also be thrown into doubt following the premature resignation of the agency’s chief executive, Elmer Funke Kupper. Voice,.
2. Chicago Mercantile Exchange Group
CME Group is one of the founders of the "Post-Trade Distributed Ledger Working Group" and has currently carried out very active actions in the industry through its investment arm CME Ventures .
CME Group is unique among its peers. It has always pursued a diversified investment strategy across industries and has successively invested in distributed accounting startup Ripple, blockchain investment group Digital Currency Group and Digital Asset Holdings. Beyond that, however, CME Group has yet to speak publicly about its conduct in technology and the larger industry.
3. Deutsche Börse
Deutsche Börse, the operator of Germany’s Frankfurt Stock Exchange, is another player on this list, and it also participated in Digital Asset Holdings’ $60 million financing in January this year.
However, unlike its co-investor ASX, Deutsche Börse has been less vocal about its support for the technology.
In an interview in February, Deutsche Börse said it was working on a proof-of-concept for the technology, although it has yet to release any findings or test results.
4. Dubai Multi Commodity Trading Center
In the Middle East, blockchain-related activities are relatively scarce, and this situation continued until the recent opening of the Global Blockchain Council. The 32-member Global Blockchain Council is a group of startups, financial firms and tech giants that oversees technology applications and the impact they are having.
Built on the basis of these members, Du Multi Commodities Center is a special economic zone and commodity circulation center responsible for overseeing the trading of precious metals and other tangible commodities.
DMCC announced in February that it was engaging in a technology trial with Bitcoin startup BitOasis to explore how blockchain technology could improve its personnel onboarding process.
5. Japan Exchange Group (JPX)
Japan Exchange Group is a relatively active stock market operator in Asia. It announced its interest in the industry in February and has officially formed an alliance with IBM. Become a user of Blockchain-as-a-Service (BaaS).
At the time, reports stated that Japan Exchange Group was embarking on a proof of concept to study the role of blockchain technology in creating a new trading system for low-liquid assets, with the final results to be released through a report later this year announced.
Earlier this month, Japan Exchange Group also announced that it is working with the Nomura Research Institute (NRI) to conduct trials to study how the technology can be applied to the securities market.
6. Korea Exchange
Korea Exchange, South Korea’s only stock exchange and one of the new entrants to this list, announced in February that it would seek to launch a counter via blockchain technology trading platform.
In statements to local news outlets, Korea Exchange said it hopes the technology will help reduce costs. Details about the trial and the company's involvement in the group were not released.
7. London Stock Exchange (LSE)
The London Stock Exchange is one of the founding institutions of the “Post-Trade Distributed Ledger Working Group” and when it comes to experiments on blockchain technology, the LSE It is one of the most dynamic but also the most low-key institutions.
The London Stock Exchange is one of the first groups to follow in the footsteps of startup R3, and it is the first to say that large financial firms will look to use collaborative models to conduct blockchain testing, beyond R3’s frame.
It was also from that time that some large financial companies began to participate in private proof-of-concepts and operations in certain areas of the capital market involving various parties.
In addition, like Kouvola Innovation and Japan Exchange Group, the London Stock Exchange is also one of the initial customers of IBM's Blockchain-as-a-Service (BaaS).
8. Nasdaq
When it comes to testing blockchain technology, Nasdaq is probably the most proactive organization. US stock marketMarket operator Nasdaq first launched Linq, a private equity trading platform, in 2015, thus becoming the first financial institution to conduct a blockchain proof-of-concept. The platform is currently still in the testing phase.
In addition, Nasdaq has also reached a cooperation with blockchain solution provider Chain and allows its internal experts to speak openly about blockchain technology.
In 2016, Nasdaq continued this momentum. For example, it previously revealed that it is working with Estonia’s Nasdaq OMX Tallinn Stock Exchange on a trial to use blockchain technology to reduce various obstacles to shareholder voting.
9. New York Stock Exchange (NYSE)
The New York Stock Exchange was one of the first companies to take an interest in the industry. In 2015, the NYSE issued two important announcements. The statements are all related to Bitcoin.
In January 2015, NYSE invested in the Bitcoin service company Coinbase as part of its Series C financing. At the time, NYSE Chairman Jeffrey Sprecher said the investment showed confidence in the widespread use of digital currencies by millennials, whom he described as having a more progressive view of value exchange.
The NYSE will continue to launch a Bitcoin price index in May, which will also become a competitor to CoinDesk’s Bitcoin Price Index (BPI), which is plotted with transaction data from the Coinbase trading platform.
10.TMX Group
TMX Group, the operator of the Toronto Stock Exchange, has never expressed a clear opinion on blockchain technology.
However, with the hiring of Anthony Di Iorio (one of the co-founders of Ethereum) as the agency’s first chief digital technology officer, TMX also publicly expressed its interest in the blockchain for the first time in March this year. Interest in chain technology. The next-generation network has become one of the most important blockchain applications in the public eye following its product launch in March.
Nonetheless, TMX Group has stated that it is in the early stages of generating a blockchain strategy and that it may soon be testing the technology. (Babbitt)
11. Puyin Group
Puyin Group launched Puyin, a tea-based digital currency. Puyin is a high-quality Tibetan tea asset that has been warehousing, appraised, evaluated and confirmed by three parties. It is encrypted A digitally issued standard digital currency.

⑤ Blockchain companies cooperate with central banks of many countries to develop CBDC. It is possible for central bank digital currencies to adopt blockchain.

As we all know, the legal digital renminbi uses a centralized ledger based on the UTXO model. The People's Bank of China is responsible for the unified maintenance and management, which is not consistent with blockchain technology, which uses decentralized distributed ledgers as one of its core mechanisms. And blockchain technology companies use the advantages of blockchain technology to participate in central bank digital currency (CBDC) is a new breakthrough and new application of blockchain technology.

ConsenSys participates in CBDC research and development

It is reported that ConsenSys has published "Blockchain Solution for Central Bank Digital Currency (CBDC)" on its official website. The article stated that digital currency can provide Cheaper cross-border remittances, improved inter-bank payment settlement and accelerated retail market innovation, etc. If central banks do not issue their own digital currencies, it will lead to markets relying on "private payment tokens", potentially creating a risk of failure and financial problems for private entities, as private tokens may not be available to everyone, Central bank digital currencies will bring risk-free, widely used alternatives.

Charles d'Haussy said that in 2016, ConsenSys began to work on CBDC through cooperation with the Singapore Monetary Authority and the South African Reserve Bank, and also gradually developed cross-border payment technology business. "Building on this, we are exploring a larger concept - 'programmable money', which any CBDC with a token architecture can support. CBDC is a perfect iteration of electronic cash that can improve the utilization of central bank funds. efficiency, ensuring a more efficient value chain.”

In addition, ConsenSys recently released a compliance service to help exchanges and decentralized finance (DeFi) projects identify possible issues related to Ethereum issuance. Token trading activity related to criminal activity. Lex Sokolin, co-head of global fintech at ConsenSys, said, “More and more people are building decentralized applications, which is part of the puzzle. What we are trying to do is make activities on decentralized financial infrastructure more Safe, transparent and easier to track."

With its strong blockchain technology background, ConsenSys has participated in the research and development of central bank digital currencies in countries such as Australia, France and Thailand, which may integrate blockchain technology with CBDC become possible.

The feasibility of using blockchain technology for CBDC

Regarding the question of whether blockchain featuring decentralized distributed ledgers can be combined with centralized central bank digital currency Yao Qian, director of the Science and Technology Supervision Bureau of the China Securities Regulatory Commission, pointed out that whether CBDC adopts blockchain technology is still controversial. A typical view is that the decentralization of blockchain conflicts with the centralized management of the central bank, and it is not recommended for CBDC to adopt it. The technology.

However, blockchain technology is developing at an unprecedented speed and is deeply integrated with various mainstream technologies. Therefore, no matter from a technical perspective or a business perspective, the blockchain in real applications is in line with the "original teachings". The understanding of "ism" is different. How to use blockchain technology to better serve distributed operations under centralized management may be the current direction that CBDC needs to focus on exploring..

Yao Qian believes that although the technical characteristic of blockchain is that it does not rely on central institutions, it does not mean that it cannot be incorporated into the system of existing central institutions. As long as it is properly designed, the central bank can just use it Blockchain effectively integrates distributed operations and better realizes centralized management and control of CBDC. There is no inevitable conflict between the two. As an emerging technology that may become the future financial infrastructure, blockchain helps achieve distributed operations without affecting centralized management for the dual model of central banks and commercial banks. Bottom-up "exchange" can formulate a new CBDC implementation plan, which also achieves the goal of "centralized management and control, distributed operation".

A digital currency research project announced by the Reserve Bank of Australia is exploring the potential use and impact of a central bank digital currency (CBDC) using distributed ledger technology (DLT).

Under the project, Australia will develop a proof of concept for issuing a CBDC in the form of a token that market participants will be able to use for financing, settlement and repayment on an Ethereum-based DLT platform. Tokenized syndicated loans. The project is expected to be completed around the end of 2020, and various project participants plan to release a thematic report on the project and its key findings in the first half of 2021.

⑥ How to comply with blockchain project compliance

The current compliance of blockchain projects is divided into two sections:
First, blockchain currency issuance project compliance Regulations: Foundation + Legal Compliance Opinion

Often referred to as ICO, IEO, etc., first of all, we first establish overseas entities. Generally, Singapore foundations are the most common currency-issuing entities. It is a non-profit company in the form of XX FOUNDATION LTD. Finally, a Singaporean lawyer issued a legal compliance opinion. The content of the legal opinion included a modification of the white paper and a TOKEN non-securitization certificate, mainly to make the project comply with Singapore law. This legal opinion will also be used when the project is docked with the exchange for currency listing in the later stages of the project.

⑦ Is the blockchain major an unpopular major?

Yes

1. What is blockchain

Blockchain is a new type of Internet technology. Simply put, it is a decentralized distributed ledger. It relies on the underlying cryptography foundation and is completely built on the Lucky Network. It is a kind of transparent operating rules. Currently, there are many engineers in this field in the society, mainly in technology. For now, I am very optimistic about the development prospects. From the perspective of academic research, this kind of advanced We can also learn from ideas, and they may be able to solve many practical problems in the future, such as financial mechanisms, privacy issues, etc. The technical threshold for learning blockchain is higher than that of other Internet technologies. When the trend becomes more popular, more people will naturally rush to it. Moreover, it is still a relatively small group of people who want to learn.The language is mainly based on the Go language. In addition, you need to learn more mathematical knowledge, algorithms, cryptography, etc., which is relatively difficult. Of course, the salary when looking for a job will be relatively good, and both ability and reward are successful. Proportional. What's more, two of the nine newly added occupations this year include the blockchain industry, which shows that this industry is getting more and more attention.

However, the banking and finance industry does not need a complete transformation of processes to adopt blockchain technology, and financial institutions are beginning to consider the use of blockchain technology. Blockchain is used in traditional banking services. Additionally, the ASX is planning to use a new blockchain-based system to manage Australia’s financial markets by the end of 2020.

Thirdly, blockchain will be integrated into government agencies in the future. The Estonian government has taken the lead in implementing it at the government level and can contain the information of all residents and citizens.

In the future, the demand for blockchain experts will grow rapidly, especially blockchain engineers and experts who already have relevant experience. Although it is possible that the start-up company you enter will fail due to immature technology or Investors were dissatisfied and withdrew their capital and went bankrupt, but blockchain is still a high-demand industry in the future.

Judging from the fact that the world is now starting to recruit talents, for example, in Australia’s Global talent project, Fintech has become an important field among the seven fields they need, and so far, no matter the number of people who have applied and the number of people invited are the smallest, because this industry is still relatively new in many countries. Compared with other fields such as agricultural technology, advanced manufacturing, medical technology, etc., which have many PhD or postdoctoral applications, current Fintech applicants still have a lot of industry experience to apply, which shows that talents in this industry are still very scarce, whether it is Domestic or foreign.

⑧ Research on energy blockchain and dual-carbon strategy｜Reject waste: convert food residues into renewable energy

Reject waste: convert food residues into renewable energy

One thing we can think about: If wasted food were a country, it would be the third largest emitter of greenhouse gases in the world after the United States and China.

Food waste has become an increasingly serious global problem. Australia alone throws away 7.6 million tonnes of food every year. That's enough to fill 13,000 Olympic swimming pools.

When food waste is transported to landfill, it releases biogases such as methane. Methane is a greenhouse gas that is 28 to 100 times more powerful than carbon dioxide.

The United Nations estimates that 8%-10% of global greenhouse gas emissions come from food waste. In Australia, it's about 3%.

Food waste is bad for the climate – but there are always exceptions.

Breaking down food scraps

How to dispose of food waste in Western AustraliaWhat about material waste? Chris Bühlmann, a PhD student at Murdoch University, has published research on how food waste can be used to produce renewable energy.

Chris Bühlmann said that the biological process of anaerobic digestion contains a lot of opportunities (Note: Anaerobic digestion refers to the decomposition of biodegradable organic matter by facultative and anaerobic bacteria under anaerobic conditions. Digestion technology for CH4, CO2, H2O and H2S).

Anaerobic digestion can produce renewable energy by breaking down food scraps into biogas, a mixture of methane and carbon dioxide, he added. This sounds like a win-win solution, but how to implement it?

The solution is simple: capture methane from decomposing food and burn it. Like burning other hydrocarbons, the chemical reaction releases heat (aka energy) and carbon dioxide (CO2).

Releasing carbon dioxide is certainly not a good thing, but it is even worse when more is released into the atmosphere than is extracted and utilized. Fortunately, the carbon dioxide produced by burning methane can be absorbed by the next generation of crops through photosynthesis. This means excess carbon dioxide is not released into the atmosphere.

In addition, there are other benefits.

Chris Bühlmann said that as coal-fired power generation is gradually replaced by renewable energy, the excess carbon dioxide produced by anaerobic digestion will also be offset. And the carbon dioxide offsets are greater than people think.

A recent environmental sustainability study on the anaerobic digestion of household food waste showed that one ton of food waste in a landfill will produce 193kg of carbon dioxide equivalent. And generating renewable energy through anaerobic digestion offsets 39 kilograms of CO2 equivalent per ton of food waste.

This will save Australia nearly 300 million kilograms of carbon dioxide emissions each year.

Developing the anaerobic digestion industry

Anaerobic digestion can not only produce biogas, but also produce natural by-products such as lactic acid, which is also the focus of Chris' research.

Chris said that the lactic acid market has been growing rapidly globally, with a recent forecast of a compound annual growth rate of 8% from 2021 to 2028.

Lactic acid is used in cleaning products, pharmaceuticals, food and cosmetics. Producing the chemical in a carbon-neutral process makes anaerobic digestion more feasible.

War on Food Waste

In an ideal world, there would be no food waste. Surplus food can be given to the hungry.

But in the real world, the problem of food waste is not going away anytime soon. Therefore, Chris believes that anaerobic digestion is a method of utilizing food waste.

Currently, most food waste ends up in landfill, which not only contributes to climate change, but also recovers little economic value from food waste, he said.

Biorefinery processes can recycle this food waste to produce valuable industrial biochemical products, modern biomaterials and biofuels, thereby replacing those produced from fossil resources.

At the same time, with researchers like Chris, we have reason to hope that in the future, food waste can be converted into more renewable energy.

⑨ Block Does blockchain have a "money" future?

Does blockchain have a "money" future?
This year, blockchain has become popular in China, and all taxi drivers know that it is a new technology in the Internet economy. tuyere. The latest data released shows its popularity in China - World Intellectual Property Organization statistics show that China applied for 225 blockchain technology patents last year, accounting for more than half of the world (406), followed by the United States (91) and Australia (13 items). These patents do not cover the field of cryptocurrency.
There are reports that Chinese Internet companies and financial service providers are competing to apply for patents on this "distributed ledger" technology, believing that it will revolutionize finance and other supply chains. It has nothing to do with "coin speculation". In the eyes of blockchain water testers, new technologies can make up for a crucial link - credit.
The transaction volume is not large, but financial giants dare not take it lightly
Blockchain is a decentralized recording system. The ledger of the blockchain is jointly recorded by all nodes participating in the transaction. Therefore, From investors to Internet hackers, they are all interested in the unprecedented "authoritative and tamper-proof" characteristics of blockchain.
Many "coin speculators" know that China has one of the largest number of "mines (computers involved in blockchain calculations)" for Bitcoin and other blockchain currencies in the world. Similarly, from 2012 to 2017, six of the nine companies with the most blockchain technology patent applications were from China.
However, the most active patent applicant in the past five years has been the US-based payment giant Mastercard, followed by Liechtenstein’s n-chain holdings.
Research institute Guangzhou Lianrui pointed out that famous companies applying for blockchain patents also include Bank of America and British Telecom. Bank of America plans to develop a person-to-person payment system where all parties can transact under pseudonyms; British Telecom's technology can detect attacks on the blockchain; Mastercard focuses on payment tracking and uploading sales data to the blockchain.
In fact, the current transaction volume of the blockchain system is still a drop in the bucket compared with the mainstream world financial transaction system. The giants are actively deploying patents to take precautions and avoid being exploited in the future.Put up obstacles.
Blockchain will convince you that this hairy crab comes from Yangcheng Lake
In the view of Dr. Shen Jie, an Internet of Things expert and leader of the overall group of the National Internet of Things Basic Standards Working Group, the distributed ledger of blockchain and The credit system brings opportunities to solve some credit problems, and through this, financial value can also be discovered.
"In the circulation of agricultural products, data is easily adulterated and lost." Shen Jie gave an example. For example, there are many hairy crabs on the market that claim to be produced in Yangcheng Lake, and they all have certificates or some "authoritative" data records to prove it. , but so many hairy crabs cannot all come from Yangcheng Lake. How do consumers know which ones are real?
"Today's traceability of agricultural products requires many links, from seedlings, chemicals to the environment, and all kinds of data must be complete. However, the lack of credit in China is now a serious problem, and consumers cannot confirm that they are good agricultural products. Agricultural products We cannot sell at high prices, and farmers’ profits are getting thinner and thinner.” Shen Jie said, “Now the government and e-commerce companies use a single force to promote traceability, and the cost is very high.”
Internet of Things technology uses a large number of devices to collect physical data To better perceive and manage the world's information, it is originally a good means of traceability; but if there is only the Internet of Things, and each subject transmits data to the platform, the possibility of fraud and tampering cannot be ruled out. Shen Jie said: “To ensure that everything from the device to the platform cannot be tampered with, the credit reporting mechanism at the bottom of the blockchain can be used.”
According to reports, companies such as JD.com are trying to introduce blockchain technology in agriculture , so that every step of a cow's data from birth to slaughter to market shelves is uploaded to the blockchain, making it trustworthy.
A piece of land may be turned into an asset by blockchain credit reporting
“In the past, the value mining of entities in the physical world in circulation was insufficient.” Shen Jie said, “For example, I have A field, but no one invests in it, it is just a field. If it is digitized, it can be traded and rights and interests can be shared."
Shen Jie believes that the Internet of Things could have mapped this field into a digital asset. But in the past, it was not easy for financial institutions to use IoT data, and blockchain has made the combination of sensor data and finance possible.
“The Internet of Things plus blockchain can help banks and insurance companies obtain reliable data and solve the problem of information asymmetry. A credit reporting mechanism has been established between farmers and financial institutions.”
Shen Jie An ongoing case was introduced, which is to apply blockchain technology to fisheries. IoT sensors can monitor and manage the water quality of fish ponds, and can also help financial institutions collect farmer data and grant loans. While farmers get more profits, the quality of their products is improved and traceable.
And blockchain data has cross-platform credibility. "Alibaba Sesame Credit Points are meaningless outside Alibaba's system." Shen Jie said that blockchain technology relies on collaboration and data transmission among multiple entities, and will make the financial value of data as real as the physical world.
From medical insurance to game points, trust is no longer difficult
Jiangsu HengWei Information Technology Company is an early company involved in the research and development of blockchain technology. Xu Yuchun, the person in charge of the company, said: "You can understand blockchain in a popular way as 'distributed electronic ledger technology that is open to the entire network'. It achieves low-level The establishment of cost-based credit system and value transfer can solve the pain points and difficulties in many fields such as finance, public welfare, supervision, and anti-counterfeiting."
Xu Yuchun said that using blockchain technology, the "three aspects of medical care, medical insurance and medicine can be realized" In "Medical Linkage", health and medical data query and usage records cannot be tampered with; in finance, the use of blockchain technology can realize the authenticity and traceability of corporate credit data, realize supply chain traceability and anti-counterfeiting, automated smart contracts, orders Performance tracking, receivables management, collateral certification and other functions.
Perhaps it is precisely because of the inherent openness and transparency of blockchain that it fits well with China’s application scenarios that lack trust, thus triggering the enthusiasm of enterprises for R&D and patent applications.
Shen Jie believes that in some areas that are already digitalized, the credit advantages of blockchain will emerge faster.
“One is digital copyright, such as the intellectual property rights of Internet music. Blockchain applications may develop rapidly; the other is the gambling industry. In the past, it was difficult to avoid the possibility of fraud in gambling on the Internet. With blockchain, credit can be established ." Shen Jie said, "Another possibility is the virtual income of games, such as points. In the past, these points were useless without the game. Blockchain may promote the interoperability of various games."
Shen Jie said, Areas such as digital bank bills are also actively testing blockchain. He believes that it is still the early days of blockchain technology, and everyone is enthusiastic to promote development; but after innovation enters the deep water zone, breakthroughs in one point or one line are not enough, and the cooperation of ecological and systemic concepts is needed.

⑩ Blockchain technology and applications: a technological revolution in the future

Blockchain technology originated from "Bitcoin: A Peer-to-Peer Electronic Cash System" proposed by Satoshi Nakamoto 》, where "block" means that each information block contains a timestamp. Information blocks containing timestamps are connected to each other, and the chain of information blocks formed is a "blockchain".

Blockchain is a technical solution that collectively maintains a reliable database in a decentralized and trustless manner. From a data perspective, blockchain is a distributed database in which a single node or multiple nodes cannot intentionally change data records. Its distribution is reflected in the distributed storage and distributed recording of data. From a technical perspective, blockchain technology is an emerging technological achievement resulting from the integration of multiple technologies. After the development and improvement of a combination of multiple technologies, it forms a more efficient way of recording, storing and expressing data.
