II Application aspects of blockchain

The main application scope of blockchain includes: digital currency, transaction settlement of financial assets, digital government affairs, certificate deposit and anti-counterfeiting data services and other fields. Blockchain is a database technology that links data blocks in an orderly manner. Each block is responsible for recording a file data and encrypting it to ensure that the data cannot be modified or forged.

Blockchain is essentially a distributed database system that uses cryptography technology for multi-party participation, joint maintenance, and continuous growth. It is also called a distributed shared ledger. Each page in the shared ledger is a block, and each block is filled with transaction records. The anonymity, decentralization, openness, transparency, and non-tamperability of blockchain technology make it highly favored by enterprises and has gained More extensive application attempts.

Blockchain application scope 1. Financial field

Blockchain can provide a trust mechanism and has the potential to change the financial infrastructure. Various financial assets such as equity, bonds, bills, warehouse receipts, fund shares, etc. It can be integrated into the blockchain technology system and become a digital asset on the chain, which can be stored, transferred and traded on the blockchain.

The decentralization of blockchain technology can reduce transaction costs and make financial transactions more convenient, intuitive and secure. The combination of blockchain technology and the financial industry will inevitably create more and more business models, service scenarios, business processes and financial products, thereby bringing more impact to the development of financial markets, financial institutions, financial services and financial formats. . With the improvement of blockchain technology and the combination of blockchain technology with other financial technologies, blockchain technology will gradually adapt to the application of large-scale financial scenarios.

2. Public service field

Traditional public services rely on limited data dimensions to obtainThe information may not be comprehensive enough and may have a certain lag. The non-tamperable nature of the blockchain makes the digital certification on the chain highly credible. It can be used to establish new authentication mechanisms in the fields of property rights, notarization and public welfare, and improve the management level of public services.

Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain to meet the privacy protection of project participants and other relevant laws and regulations. Under the premise of requirements, public disclosure will be made conditionally to facilitate public and social supervision.

3. Information security field

Using the traceability and non-tampering characteristics of blockchain, we can ensure the authenticity of data sources and ensure the non-forgery of data. Blockchain technology will fundamentally change information Security issues of the propagation path.

Blockchain is reflected in the following three points in the field of information security:

User identity authentication protects data integrity and effectively prevents DDoS attacks

The distributed storage architecture of blockchain will make Hackers are at a loss as to what to do. Some companies have begun to develop a distributed Internet domain name system based on blockchain to eliminate the root cause of the current DNS registration shortcomings and make the network system cleaner and more transparent.

4. Internet of Things field

Blockchain + Internet of Things can allow each device on the Internet of Things to operate independently, and the information generated by the entire network can be protected through smart contracts in the blockchain.

Security: Traditional IoT devices are highly vulnerable to attacks, data loss and maintenance costs are high. Typical information security risk issues for IoT devices include low firmware versions, lack of security patches, permission loopholes, too many device network ports, and unencrypted information transmission. The blockchain's consensus mechanism for network-wide node verification, asymmetric encryption technology and distributed data storage will significantly reduce the risk of hacker attacks.

Trustability: The traditional Internet of Things is managed and controlled by a centralized cloud server. Due to the security of the device and the opacity of the centralized server, it is difficult to effectively protect user privacy data. The blockchain is a distributed account book. Each block is interconnected and has its own independent working ability, ensuring that the information on the chain will not be tampered with at will. Distributed ledgers can therefore provide trust, ownership records, transparency and communication support for the Internet of Things.

Effectiveness: Limited by cloud services and maintenance costs, the Internet of Things is difficult to achieve large-scale commercial use. The traditional Internet of Things realizes communication between things through centralized cloud servers. The disadvantage of this model is that as the number of access devices increases, the server faces more load, requiring enterprises to invest a lot of money to maintain the normal operation of the IoT system.

Blockchain technology can directly realize point-to-point transactions, omitting the labor expenditure of other intermediaries or personnel, which can effectively reduce the costs incurred by third-party services and maximize benefits.

5. Supply chain field

The supply chain consists of many participating entities, with a large amount of interaction and collaboration. Information is discretely stored in their own systems, lacking transparency. Information is notSmoothness makes it difficult for various participating entities to accurately understand the real-time status and existing problems of related matters, affecting the collaborative efficiency of the supply chain. When disputes arise between parties, it is time-consuming and laborious to provide evidence and pursue accountability.

Blockchain can make data open and transparent among various entities, thereby forming a complete, smooth, and non-tamperable information flow throughout the entire supply chain. This can ensure that all entities promptly discover problems arising during the operation of the supply chain system and find targeted solutions, thus improving the overall efficiency of supply chain management.

6. Automotive Industry

Last year announced a partnership using blockchain to build a proof of concept to streamline the car rental process and build it into a “click, sign up, and drive” process. Future customers choose what they want The rented car enters the public ledger of the blockchain; then, sitting in the driver's seat, the customer signs the rental agreement and insurance policy, and the blockchain updates the information simultaneously. This is not an imagination, for car sales and car registration That said, this type of process may also develop into reality.

7. Stock Trading

For many years, many companies have worked to make the process of buying, selling, and trading stocks easy. Emerging Blockchain Chain startups believe that blockchain technology can make this process more secure and automated than any previous solution. At the same time, blockchain startup Chain is working with Nasdaq to enable private companies through blockchain. Equity transfer

8. Government management

Government information, project bidding and other information are open and transparent. Government work is usually subject to public attention and supervision. Since blockchain technology can ensure the transparency and immutability of information, it is very important to the government. The implementation of transparent management plays a great role. There is a certain degree of information opacity in government project bidding, and enterprises also have the risk of information leakage during the sealed bidding process. Blockchain can ensure that bidding information cannot be tampered with and can ensure the transparency of information nature, forming a common trust among competitors who do not trust each other. It can also arrange subsequent smart contracts through the blockchain to ensure the construction progress of the project and prevent the growth of corruption to a certain extent.

There are many more applications of blockchain technology, and this is just a fulcrum of blockchain applications. In the future, blockchain technology will be applied everywhere

Ⅲ Principles of Blockchain

p>

Blockchain is a technology, but it is not a single technology, but the result of the integration of multiple technologies, including cryptography, mathematics, economics, network science, etc. You can look at it It is a distributed shared accounting technology, which can also be regarded as a database. However, this database is jointly maintained by all nodes in the chain. Each node has a ledger, because the ledgers of all nodes are consistent and different. Nodes can trust each other and have no doubts about the data, so everyone says that blockchain achieves trust technically. For detailed professional technology, you can consult some professional technology companies, such as: Jinbo Technology, which focuses on the development of blockchain-related Products, professional R&D team and perfect after-sales service, you can call for consultation.

Ⅳ See how the world's top ten stock exchanges play with blockchain

Institutions have begun to experiment with this new technology.
DTCC is a U.S. clearinghouse that processes quadrillions of dollars in transactions each year, and Visa, the global credit card processing network, is just some of the best-known non-bank pilot projects. That said, some financial sectors are certainly more active than others.
Major stock and commodity exchanges are arguably the most active institutions involved in blockchain experiments. For example, Nasdaq, a major U.S. stock exchange provider, even released its own blockchain trading model last fall. The program, called Linq, can trade and track private company stocks. Nasdaq is positioning it as an early experiment in blockchain technology to expand the scope of major stock trading and even new asset classes.
Blockchain_stock exchanges
Although there are more differences in subtle areas, 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 the application of blockchain technology, the ASX is definitely one of them One of the most ambitious companies, it invested more than $10 million in startup Digital Asset Holdings in the industry in January as part of its research and development push.
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 CEO 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 not yet reviewed its expertise in technology and updates.Large industry-wide acts speak out publicly.
3.Deutsche B�0�2rse
Deutsche B�0�2rse, the operator of Germany's Frankfurt stock exchange, is another player on this list, and it also participated in the Digital Asset Holdings’ $60 million financing.
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 their impact.
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 media, 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. U.S. stock market 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 based on trading data from the Coinbase trading platform.draw.
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.
Nevertheless, TMX Group has stated that it is in the early stages of generating a blockchain strategy, and that it may soon conduct technical tests

Ⅳ The top ten most profitable blockchain APPs Making money from mining is so easy!

As network technology becomes increasingly mature, the word blockchain is mentioned by more and more people. In 2018, blockchain became the first choice project of many investors, and the number of mobile blockchain software is also gradually increasing. From dozens in 2013 to hundreds or even thousands of blockchain companies in 2019, we can see how hot the blockchain market is. In the minds of many friends, blockchain is something that allows one to make money. Yes, blockchain does allow many people to make money, but now there are also many unscrupulous fake companies in the blockchain market. In the name of blockchain, it is actually a deceptive business. So friends, when playing with blockchain, you should also keep your eyes open and choose a formal and trustworthy platform!

Today I have collected and sorted out 10 recently popular blockchains for you. Chain software, these platforms are all real and reliable, and each platform has a large number of users. If you are also a friend who likes blockchain, then don’t miss the content I bring!

After understanding the blockchain, let’s start the text. The content brings you an inventory of the ten most profitable blockchain software↓↓↓↓↓

Ⅵ How to understand the blockchain

Nowadays, technological development is changing with each passing day and the situation is surging. , if you and I are a little lazy, we may be out. No, the new "hot internet celebrity" - blockchain is here. Since the beginning of this year, blockchain has become one of the hottest knowledge points in the technology world, and it has become increasingly dazzling in fields such as digital finance, Internet governance, and big data computing.

Blockchain technology also has broad application prospects in the military field and is very likely to quietly subvert future wars.

This is not Xiaole bragging. "In matters involving the three armed forces, nothing should be more important than secrecy." We must know that in the future information battlefield, confidentiality is the key to determining the outcome of a war. Because the blockchain system has many characteristics such as information independence, confidentiality and integrity, it can achieve the perfect combination of data storage and data encryption. It is also extremely resilient after being attacked and can protect highly sensitive data.It is said to be of great help in winning the war.

According to the information collected by Xiaole, some countries are currently planning to build a blockchain information platform and have begun to study the application potential of blockchain in several scenarios such as military satellites and nuclear weapons; a certain International organizations are currently evaluating the performance of blockchain technology in military logistics, the Internet of Things and other fields.

If digital currencies such as Bitcoin are blockchain 1.0 applications, then the "smart contracts" that provide strong guarantees for the security of network transaction data are blockchain 2.0. There will be 3.0 in the future - from DAO (blockchain self-consistent organization), DAC (blockchain self-consistent company) to the blockchain society.

“Use informatization to cultivate new kinetic energy, use new kinetic energy to promote new development, and use new development to create new brilliance.” I believe that blockchain, the “new kinetic energy” of technology, will bring us more surprises: “ "With a machine in hand, I own the world", "trade autonomy", wider sharing, optimally adapted life model... Blockchain technology will create a more honest, convenient and efficient big data era.
