A. Blockchain in the past 12 years: In what fields has it been applied?
#「 Shining Moment」Theme Essay Competition Issue 2#
Countless people have Talk about the applicable scenarios and application opportunities of blockchain. But in fact, it is very stupid and ridiculous to simply and crudely bundle blockchain with all businesses.
If you just use the word "blockchain" (rather than the technology behind it) to hype it, the result will be in vain. But if used properly, blockchain can indeed promote the development of certain economic sectors.
To achieve this goal, you need to take it slowly, step by step. Gartner experts believe that blockchain is currently on the verge of “escape from fantasy” stage. At this stage, its technical shortcomings were fully exposed, and most media from all walks of life were critical.
So, are there any good products that are truly based on blockchain? If so, in what areas?
First of all, financial services are a good choice. After all, many traditional intermediaries suffer from low transparency and high commissions. Currently, many large banks are already researching and testing decentralized solutions. So what are the options available on the market now?
Netting is a good example. It is based on Hyperledger Fabric and is capable of offsetting multiple positions or payments resulting from transactions between two or more parties. Often used to determine which party should receive remuneration in a multi-party agreement. Netting, as a general concept, has many more specific uses in financial markets (in securities trading).
In addition, there is endless discussion about blockchain bonds, mortgages and bank guarantees. Almost all big banks, including Islamic banks, are trying this approach.
Hyperledger Fabric and Corda blockchain technologies are also often used in other use cases, but the prospects require us to draw final conclusions through continued follow-up and observation.
Bank of America, Goldman Sachs, Citibank, Morgan Stanley, JPMorgan Chase, Bank of China and Commonwealth Bank of Australia have all achieved good results in 2019. In addition, in the banking industry, people often talk about cross-border financial transactions, and there is even an intention to get rid of SWIFT.
Some people believe that blockchain technology has great prospects in copyright protection and combating data fraud. For example, for the purpose of copyright protection, the startup Sputnik DLT developed the Depositor service on the Waves platform.
Likewise, Emernotar is based on EmeA similar solution from rcoin uses the SHA-512 algorithm. According to the developers, businesses and lawyers can use the Emernotar service to sign contracts, use online services to collect user consents, and creative industry representatives to confirm copyright.
The democracynotary.org platform, powered by Emercoin technology, aims to protect important election-related information. Although the blockchain cannot yet guarantee the anonymity of voting during the election process, it can at least guarantee the authenticity of voting.
The effectiveness of this platform was recently put to the test in a Macedonian referendum on ratifying a treaty with Greece that called for changing the country’s name to “North Macedonia.” ". The platform notarized public reports from the referendum process, thereby blocking the spread of false information.
Blockchain use cases are extremely promising in the registration of real estate transactions. Last year, there were attempts to leverage smart contracts on the Ethereum blockchain to conduct such buy/sell transactions in jurisdictions. While not all local legislatures understand what lawyers are doing, there have been and will be attempts.
For example, the most famous example was a deal to sell 10 acres of land through a decentralized Propy marketplace in California, conducted entirely in Bitcoin and using blockchain To register. Since then, the EU has also completed its first blockchain real estate sale.
In December 2018, the Swiss Financial Market Supervisory Authority approved the business model of the blockchain company “Blockimmo Real Estate Company”. Currently, the Blockimmo platform is in a testing phase and is available to residents of Switzerland and Liechtenstein. After that, the company plans to enter other markets throughout Europe.
Some experts are very optimistic about the application prospects of blockchain in the wholesale and logistics fields; but at the same time, some experts believe that it has no use in this field. However, as consumers, we should recognize the success that has been achieved in the industry.
In the late autumn of 2018, oil giants BP and Shell, as well as large banks and companies, launched the Vakt blockchain platform, which aims to optimize the commodity transaction process - including converting paper documents into smart contracts .
At the same time, the UAE is also using blockchain technology in the field-Maqta Gateway LLC launched the first blockchain logistics solution in Abu Dhabi. The Silsal blockchain technology developed by the company can improve logistics and freight efficiency. Maqta Gateway hopes to use DLT technology to reduce paperwork, facilitate real-time status updates and speed up information sharing.
Last fall also launched the IBM Food Trust Blockchain Platform - based on Hyperledger Fabric technology and designed to regulate the food industry supply chain. Well-known companies such as Carrefour, Nestle, Dole Food, Tyson Foods, Kroger, Unilever, and Walmart are among the Platform members. Monthly fees for IBM blockchain services range from $100 to $10,000, which explains why these industry giants are willing to invest in this area.
The decentralized Shelf.Network auction protocol was launched in the fall of 2017. Car dealers can conduct car sales and leasing transactions through the platform.
A year later, the auction network received investment from Japanese IT giant Broadleaf. At the same time, Broadleaf has also obtained a license to supply Shelf.Network technology to establish a trading network for automobile and parts sales in Southeast Asian countries (including Japan, Myanmar, Thailand, Indonesia, Vietnam, Laos, Australia, India and Singapore).
By the end of 2018, 60,000 vehicles from the United States had joined the service network. Shelf.Network also implements interaction with the Carfax web service, through which vehicle history reports can be provided to individuals and businesses. For example, startup Auto1 Group GmbH recorded the purchase of a car in Germany through blockchain for loan and insurance products, significantly speeding up the transaction (which would have taken two weeks to complete with traditional paperwork).
A survey of large companies conducted by the IBM Institute for Business Value shows that by 2021, blockchain will play a key role in the automotive industry, and at the same time, blockchain will also be used in the aviation field. . For example, S7 Airlines and Alfa Bank (Russia) have enabled real-time payments for aircraft fuel costs by applying smart contracts on the Hyperledger blockchain platform.
All walks of life in the industry believe that DLT technology can simplify and speed up mutual settlement processes, eliminate various financial risks, and automate processes. As in the field of wholesale logistics, this technology also has important application significance in the field of transportation.
Blockchain technology is also gradually penetrating into the public sector and is widely used in document authentication processes. For example, the Proofstack service is able to archive files with the owner’s personal signature, date and time stamp, and then writes the archive hash to the blockchain. Users can also choose to affect the timestamp typecountry, and the storage location (computer, cloud) required to generate the archive. Created archives allow people to identify when and by whom a file was archived. At the same time, the application of blockchain in the judicial system is becoming more and more popular. For example, ServeManager and Integra have applied blockchain technology to services that track subpoena delivery.
In China, government-backed blockchain solutions continue to develop rapidly. Its judicial blockchain system "Tianping Chain" has collected about 1 million pieces of online evidence data just three months after its release. All materials submitted on the platform are DLT certified, totaling 190,000 documents. The platform electronic evidence system was jointly developed by the Beijing Internet Court, the China Industrial Control System Emergency Response Team (CICS-CERT), the Research Center of the Ministry of Industry and Information Technology, the Network Internet Group and the TrustDo blockchain startup. The platform is based on the hyperchain infrastructure of the Internet giant network, optimizes the evidence collection and storage process, and ensures the authenticity of the data through the blockchain. In addition, the platform also achieves the purpose of saving time and resources by reducing Internet-related litigation costs.
As a global leader in container shipping, Maersk began using Insurwave blockchain solutions last spring. The marine insurance platform was jointly developed by consulting firms EY and Guardtime and is based on Microsoft Azure cloud technology. In the first year of cooperation with Insurwave, Maersk plans to insure 1,000 ocean-going vessels, and the total number of digital transactions will exceed 500,000.
Currently, platform users include Willis Towers Watson, XL Catlin and MS Amlin. Developers are trying to expand Insurwave's capabilities to expand insurance into the aviation and energy sectors.
Calastone, a British financial technology company specializing in investment flow management, announced that it will transfer all calculations to the blockchain. The company expects the technology to help cut billions of dollars in costs across its global settlement division. Calastone provides risk assessment management services, IT infrastructure and payment solutions to more than 1,700 companies, with clients including JP Morgan Asset Management, Schroders and Invesco.
If the enterprise's goal is to achieve transparency of transactions and information entered into the DLT registry, this will create an excellent application scenario for blockchain; however, if the enterprise is pursuing anonymity or "tracking "In financial transactions, there is no opportunity for blockchain to exert its influence.
Singapore Power Group (SingaporePower Group has launched a blockchain trading market for renewable energy (REC) certificates. Its company representatives said the "in-house developed" platform was designed to improve the security, reliability and traceability of such certificate transactions.
REC certificates are certificates that certify the amount of energy released by solar panels and are sold by Cleantech Solar Asia and LYS Energy Solutions. City Developments Limited and DBS Bank, who are interested in purchasing certificates, are both very interested in the platform. Katoen Natie Singapore has also joined the platform and plans to launch renewable electricity production capacity soon.
KT Corporation, South Korea’s largest telecommunications company, has also launched its own blockchain network, with distributed registration technology involved in user authentication and improving international roaming services. This enables KT to securely transfer customer data to its partners. Network bandwidth can handle 100,000 transactions per second.
Time will tell whether these initiatives gain mass market acceptance. Likewise, the applications of blockchain in power, data, and user-identified accounts/records/transactions are old news.
At the end of 2017, the Massachusetts Institute of Technology (MIT) used the Blockcerts wallet (which can issue a "verifiable, tamper-proof" authentication certificate) to more than a hundred people through the Bitcoin blockchain. Graduates were issued digital diplomas.
The pilot project is supported by software company Learning Machine, which has been involved in the development of Blockcerts together with Media Lab.
The purpose of this is to allow students to become the true owners of their own files. Learning Machine CEO Chris Jagers said that even if the agency ceases to exist, people will be able to extract important official information stored in it.
The same approach is used by Tbilisi University of Business and Technology: the university uses a similar blockchain platform, Trusted Diploma, through a partnership with Emercoin. The platform is able to restore registration data (subjects studied, quality of training and scores obtained) with the help of blockchain. From this point of view, in the future, blockchain may be useful in further promoting digital learning methods.
B. Several of my friends are playing with blockchain. Is it reliable?
Blockchain is also a relatively new thing, and it isMany people are paying special attention to blockchain. Blockchain can be loved by many people and can also receive investment from many people. Many people particularly want to invest in blockchain, and they also hope to be able to invest in blockchain. to get more rewards for yourself.
There are many people who want to invest in the blockchain, but they may not necessarily understand the blockchain, and they do not know how to operate the blockchain. If everyone around them invests in the blockchain, they themselves If you invest, you may suffer relatively large losses. Some people may have this question: Several of my friends are playing with blockchain, is it reliable? In fact, I think blockchain is not necessarily reliable. There are three main reasons why I say this:
First, blockchain is easily affected by the market.
The reason why I think blockchain is not necessarily reliable is because I think blockchain is easily affected by the market. When the market fluctuates greatly, the value of blockchain may increase. decline, and it may not be able to recover as soon as possible. If some people invest because of the value of the blockchain, they may suffer relatively large losses, and they may lose all their money.
The above is my opinion.
C. What is blockchain technology, what are its benefits, and what is building digital trust
The recent surge in the value of digital currencies since their first appearance in 2009 has triggered security concerns Discussion in the field, discussing the benefits of blockchain. Blockchain is a technology that can facilitate the type of trust that is sorely lacking in certain digital transactions.
Today, people are exchanging cryptocurrencies at an increasing rate. But what makes cryptocurrencies so trustworthy? The answer is simple: everyone has their own blockchain.
What is blockchain technology, what are its benefits, and what is building digital trust?
Shifting the Burden of Trust
When we deposit money somewhere, we trust that it will not modify our account. Likewise, when we make a retail transaction, we expect to get enough goods in exchange for the money we spend. By adopting blockchain, cryptocurrency providers have removed the burden of trust from third-party financial institutions
Blockchain is a peer-to-peer network database that breaks each transaction into its own blocks. In addition to cryptocurrency transactions, these blocks can also contain other sensitive assets such as identity information, patents, land titles, medical data, and more.
What is blockchain technology, what are its benefits, and what is building digital trust?
Once transactions are grouped into a block, a hash is assigned to the block so users can easily detect changes to the data. A block may contain a hash of the previous block, creating a block of blocks. This allows security professionals to trace the blockchain back to the first block or the genesis block when an attacker attempts to modify a transaction. Any changes will change the hash of the blockcolumn, requiring potential threat actors to modify all blocks in the chain to complete the attack. For this reason, most cybercriminals believe that attacking blockchains and targets is unrealistic.
More benefits of blockchain
The blockchain is distributed among all participating nodes in the network, so anyone who joins the network can access the entire blockchain . Participants can collectively assess the effectiveness of the entire chain, meaning a potential attacker would need to control more than half of the participants to alter the final blockchain.
The mechanism of this consensus varies depending on the blockchain implementation. For example, one of the most hyped coins uses proof of work, which is a mathematical challenge that participants must solve in order to add a block to the chain. Other methods include proof of stake, proof of activity, and selective endorsement, each with its own advantages and limitations.
By examining the blockchain’s audit trail, participants can see a complete record of who owns a given asset, coin or token throughout its lifecycle. In other words, they can trace an asset’s origins and past transactions. Public key encryption further ensures non-repudiation and confidentiality.
No Limitations
Today, blockchain is often used as a currency ledger to facilitate smart contracts and identity management. In addition, there are projects building database networks that use distributed technology to serve supply chains, real estate, voting systems, and more.
After all, a technology actually guarantees trust between participants and provides visibility into sensitive transactions. As encryption becomes more popular and the need for verification increases, blockchain technology will improve even more
D. What is blockchain for
What is the blockchain for?
What is the blockchain for? There are many things in the world that touch our knowledge blind spots, and blockchain is one of them. However, blockchain is often mentioned, so we also need to understand blockchain. Next, I will take you to understand what blockchain is for.
What is blockchain for 1Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.
Blockchain is an important concept of Bitcoin. It is essentially a disintermediated database. As the underlying technology of Bitcoin, it is a series of related cryptographic methods. Each data block contains information about a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
Application
1. Art industry
Ascribe allows artists toUse blockchain technology to claim ownership and issue numberable, limited-edition works in digital form for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.
2. Legal industry
BitProof is the most advanced of the many document timestamp applications that have emerged in recent years, and will make traditional notarization methods a thing of the past. Compared with free versions including Blocksgin and OriginStaemp, BitProof provides more services, including one for intellectual property. Interestingly, BitProof recently collaborated with a San Francisco IT school to put all their students’ academic certificates on the blockchain, completely redefining how diplomas and student certificates are processed and used.
3. Development industry
Colu is the first company to allow other companies to issue digital assets. Their ability to "tokenize" various assets has impressed many people. While the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu's tokens can be configured in various states and types, be able to leave and return to the system, and When storing data on the blockchain is too large, the data can be stored on the BitTorrent network.
4. Real estate industry
They plan to modernize the entire industry chain process and solve various problems faced by everyone involved in real estate, including the naming process, land registration, Agency intermediaries, etc.
What is Blockchain 2What is Blockchain
Blockchain is a new application of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. model. It is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods.
Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information, prevent counterfeiting and generate the next block. It is a set of data storage mathematical architecture constructed in a way that is almost impossible to forge or tamper with, and can be used to store all kinds of valuable data.
The Cyberspace Administration of China issued blockchain information service management regulations on January 10, 2019, which will take effect on February 15, 2019.
What is the blockchain for 3Before talking about the blockchain, let’s talk about the Internet. The Internet is now an indispensable part of us and is closely related to our lives. First of all, the biggest disadvantage is It can only transmit information. The key is that the information data on the Internet can be set artificially. For example, it is often said to browse Weibo and so on.Secondly, there are bugs in the Internet environment, which means that there cannot be equality in data ownership. This is to say that there are some disadvantages of the Internet.
Putting aside what blockchain is, let’s talk about the Internet and blockchain. Blockchain and the Internet are a parallel relationship, and they can also be a continuation of mutual complementation. So what is a blockchain? A blockchain is actually a series of data blocks that are associated using cryptographic methods. Simply put, there are many data blocks connected in a certain time sequence. It can also be said that a blockchain is a ledger. , but the account book is different from the ordinary computer account book. The blockchain account book is jointly kept by all computers in the world. The biggest feature is that it cannot be tampered with.
What can the blockchain do?
1. Machine trust
In professional terms, it is because of the blockchain The tamper-proof nature of technology fundamentally changes the centralized credit model. Build lowest-cost credit with code. In other words, as long as the code on the blockchain is executed, there is no need to worry about the possibility of stopping midway. Creating a new era of machine trust. Blockchain is expected to lead us from personal trust to the era of machine trust. In other words, his trust cost is close to zero.
2. Value transfer
The Internet can only transfer information but cannot realize the value of information. That is to say, the transition from the information Internet to the value Internet will Some fundamental changes occur. Blockchain transfer will be more convenient, while also achieving low-cost transfer of value.
3. Smart contract
This is also one of the most obvious features of the blockchain. When a pre-programmed condition is triggered, the smart contract begins execution and cannot be interrupted by either party, and cannot be deleted, modified, etc. until the end of the contract.
4. Token mechanism
Token mechanism is actually a form of value circulation. Through the tokenization of physical or virtual assets, it can work directly through the network. Mainly There are cost reductions, time savings and crossing borders. It can also be understood as proof of rights and interests. Xunlei and "LinkToken" all belong to the "Token" blockchain.
Blockchain characteristics
It has the characteristics of decentralization, anonymity, autonomy, openness, traceability, non-tampering, collective maintenance and no need for recognition. At present, we often talk about the following types of blockchains: public chain, private chain, alliance chain and side chain.
The application value of blockchain
1. Blockchain information security
Information security is one of the biggest features of blockchain, such as Facebook some time ago The leaks brought some negative social impacts. On May 8, Facebook established a blockchain department to study how to use blockchain technology.
2. Underlying technology
This is one of the most imaginative and core technologies of the blockchain. It is a highly professional academic. To give a simple example, the most famous project of this underlying technology is Ethereum.
3. Bass service
This is a series of services provided by using data generated by the blockchain, such as queries, etc. In terms of network and Tencent, both have launched their own Bass services. .
Where are the five blockchains mainly used?
At present, relatively mature areas include blockchain + medical care, blockchain + Internet of Things, blockchain + culture and entertainment, blockchain + public welfare, etc.
E. What is blockchain
What is blockchain? What changes will it bring to your future life?
Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of cryptographic methods related to each other. Each data block generated contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.
In fact, the original English version of the Bitcoin white paper does not appear in the word blockchain, but uses chain of blocks. In the earliest Chinese translation of the Bitcoin white paper, chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.
The Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations" on January 10, 2019, which will come into effect on February 15, 2019.
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-transformable. Fake distributed ledger.
So in conclusion, this is undoubtedly a new technology that changes life. In the future, the production activities of the entire society will be carried out with blockchain as the underlying logic. Many things We all have it at our fingertips, and with the integration of artificial intelligence and big data, we can easily handle things that may seem cumbersome now, such as some securities market transactions and intelligent matching of financial management activities.
To put it simply, blockchain is a network computing center that integrates people, property, machines, and goods, and packages them into a whole; putting it on an infrastructure to run.
F. What does blockchain mean and how to make money
The meaning of blockchain and how to make money are as follows:
1. The meaning of blockchain: Blockchain is After a piece of information is confirmed by multiple parties, it is finally stored inMultiple places, is a tool that can solve credit problems when trading.
2. How to make money with blockchain:
(1) Provide blockchain technology services. Form a corporate team to specialize in the development and application of blockchain technology, and provide your technical results to companies in need for use, or develop corresponding blockchain technology based on the needs of service recipients. A simple understanding is to be a middleman.
(2) Use blockchain technology to issue coins. This method is that the company acts as an issuer and releases a certain number of virtual coins for others to invest, such as Bitcoin, Litecoin, and Dogecoin. At that time, if you wanted to become an issuer, in addition to having blockchain technology, you also had to apply for a series of filing documents and materials such as business qualification certificates and currency issuance qualification licenses from relevant regulatory authorities. Otherwise, if you don’t have these documents, it would be fraud. . However, successfully preparing these documents will still test the strength and capital of the company. If the funds are not strong enough, it will be difficult to sustain.
(3) Payment for blockchain knowledge. In the early days of the blockchain market, many people did not understand what blockchain was and wanted to participate, which inevitably gave rise to a blockchain knowledge payment market. Since this year, many public accounts with the theme of blockchain have appeared, and many paid blockchain courses and small investment circles have been born.
(4) Register to receive free candies. Candy is a token that the blockchain project team rewards early users in order to attract more users to join the early use and spread. Similar to the early "Didi", in order to cultivate a large number of early users, a large number of free taxi tickets were issued to users.
G. The first village of blockchain, another good manifestation of the bubble in the currency circle
February 16, 2019, the 12th day of the first lunar month, many people are still in their hometowns Celebrate the Spring Festival. Bitcoin China founder Yang Linke posted a photo of his hometown, Ledong Village, on Weibo: The stone tablets on both sides of the Wanglou River in Ledong Village are engraved with information on dozens of currencies, including BTC. Ledong Village is known as the first village in blockchain.
As early as January 12, 2018, Yang Linke publicly revealed at a large summit that he would build a blockchain industrial village (also known as Ledong Village, Beibaixiang Town, Yueqing, Wenzhou, his hometown Bit Village). His reason is simple: "When the Internet emerged, there was Zhongguancun. When Taobao emerged, there was Taobao Village. Now that we have entered the blockchain era, we need to have a blockchain industrial village."
Yang Linke is here Murakami is very attentive to the construction of Bit. He personally participated in symposiums, development plans, on-site construction, and investment promotion. On February 23, 2018, villagers of Ledong Village participated in the "Blockchain Symposium" in the classroom of Ledong Primary School. Nearly a hundred villagers participated in the "Ledong Blockchain Forum" that day, and Yang Linke also participated.
The Blockchain Industrial Village is a public welfare project. For this reason, Yang Linke also posted a message in the circle of friends to call on friends in the blockchain circle to invest. Blockchain Village, of course, uses the currency circle method to invest, and he also posted the addresses of BTC, ETH and BCD. According to the donor presented by Yang LinkeOn the list, there are many well-known projects and founders, including Bao Erye, Chu Xia Hu, Zhu Huaiyang, etc.
As for the direction of the blockchain industrial village, the "Ledong Blockchain Industrial Village Development Plan" says this: first, popularize blockchain industry knowledge; second, provide services for the global region Blockchain projects provide a display window; third, carry out targeted poverty alleviation through blockchain to drive local economic development.
I think there is still a big gap between Ledong Village and Zhongguancun and Taobao Village. In Zhongguancun and Taobao Village, villagers rely on related industries to make a living and are engaged in related industries. At present, the things related to blockchain in Ledong Village are just displays of some digital currencies. As an emerging industry that puts technology first, the blockchain industry has a huge education cost, which is difficult for many highly educated talents to understand. As a poor village, the quality of villagers in Ledong Village is generally low, and it is difficult for them to understand the blockchain industry, let alone make a living on the blockchain. Therefore, I think it is too early to call Ledong Village a blockchain industrial village.
This is very similar to the current currency circle. Many project developers don’t have any real knowledge. They throw out a concept casually, buy a white paper on Taobao under the guise of blockchain, and start publicizing it openly, harvesting people’s IQ tax.
However, I firmly believe that blockchain is definitely the future, and bubbles are the only way to go. Only bubbles can attract some people to participate in the early stage. With the continuous development of blockchain technology and the improvement of user experience, a real blockchain industrial village will definitely appear.
H. What is blockchain technology? What are the core components of blockchain technology?
What is blockchain technology? What are the core components of blockchain technology? What is blockchain technology:
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.
The core components of blockchain technology:
Blockchain mainly solves the trust and security issues of transactions, so it proposes four technological innovations to address this issue:
The first one is called distribution A type of ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they can all participate in supervising the legality of the transaction and can also jointly testify for it.
Differences from traditionDistributed storage is different. The uniqueness of blockchain's distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally stores The data is divided into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and has equal status, relying on the consensus mechanism to ensure the consistency of storage, while traditional distributed storage generally synchronizes data to other backup nodes through the central node. [8]
No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.
The second one is called asymmetric encryption and authorization technology. The transaction information stored on the blockchain is public, but the account identity information is highly encrypted and can only be accessed with authorization from the data owner. This ensures data security and personal privacy.
The third one is called the consensus mechanism, which is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.
The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be computing power, the number of shares, or other factors. A characteristic quantity that a computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result. [8]
Taking Bitcoin as an example, it uses proof of work. Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. When there are enough nodes joining the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
The last technical feature is called smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.
In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.
Chongqing Jinwowo Analysis: Consensus MachineConsensus is the core of blockchain technology. The consensus mechanism largely determines the degree of mutual trust between nodes in the entire blockchain system, and also determines the degree of trust of other users in the data on the blockchain.
Zone What is the core component of blockchain technology? Analysis by Chongqing Jinwowo: Blockchain technology consists of three core technologies: consensus mechanism, common defense mechanism, and distributed storage.
The three core technologies are supported by machine trust, that is, through the support of network technology, breakthroughs in difficult problems such as point-to-point transactions, decentralization, non-tampering of recorded information, irreversible transactions, and information encryption are achieved through network technology support.
The development of blockchain technology is becoming more and more prosperous with the continuous expansion of applications. This powerful development force coming from the needs of various industries has caused rapid changes in blockchain technology, allowing various industries to achieve great results. The results are attracting more and more attention, and professional technologies and resources are constantly concentrated in this industry, thus bringing the development of blockchain technology into a new stage, and the impact of this development of blockchain technology has also much attention.
When talking about blockchain technology, Bitcoin has to be mentioned. Many people know that the electronic currency Bitcoin does not rely on the issuance of a specific monetary institution, but is generated through a large number of calculations by a specific algorithm. In fact, the core that truly supports Bitcoin is blockchain technology.
How does the invisible and intangible Bitcoin operate through blockchain technology? The interpretation circulated in the industry is that blockchain can be regarded as a technical solution for collectively maintaining reliable databases through "decentralization" and "trustlessness". In layman’s terms, this technology can be understood as a technology in which everyone participates in accounting. In the past, people used centralized servers to keep accounts, but in the blockchain technology system, everyone can participate in accounting and jointly identify Authenticity of records.
"Through this technology, even if there is no neutral third-party organization, two parties that do not trust each other can achieve cooperation. In short, the blockchain is like a 'machine that creates trust.'" Bubi Company It is a leading blockchain service provider in China. It has made many breakthroughs in the blockchain technology platform, can meet scenarios with tens of millions of users, and has the ability to quickly build upper-layer application businesses.
The blockchain technology used by all parties involved in recording and storing information adopts a decentralized distributed structure, which saves a lot of intermediary costs and can better ensure data security; at the same time, it has a timestamp that cannot be tampered with. It can effectively solve problems such as data tracking and information anti-counterfeiting.
Will it become the next trend of Internet finance?
Although blockchain emerged with Bitcoin, the derived value of this technology has transcended digital currency. Bubi Blockchain focuses on the innovation of blockchain technology and products. It already possesses a number of core technologies and has developed its own blockchain service platform. With decentralized trust as the core, we are committed to building an open value circulation network to allow digital assets to flow freely. Bubi has to do one thingNew technologies and products - realizing real value circulation, bringing the Internet to a new level. With the application of this technology, there will be no central organization when transferring assets, and direct transfer of assets between us can be achieved.
In the current international financial market, the U.S. Central Bank, Swiss Bank, and some insurance and futures companies are all competing to develop blockchain technology. Fang Liang introduced that in the Internet financial industry, blockchain technology will first affect financial infrastructure such as payment systems, securities settlement systems, and transaction databases; later, the technology will also expand to general financial services, such as credit systems and "anti-money laundering" "wait.
"The payment and clearing system in the financial field will evolve towards decentralization. The electronic ledger supported by blockchain technology is a reliable system that is error-free and cannot be tampered with. It has various functions for payment, clearing, transaction, confirmation of rights, etc. A profound impact," Li Yan said.
Therefore, industry insiders believe that blockchain technology may be the next trend in the Internet financial industry. As the interconnection of all things deepens, Yang Tao, assistant director of the Institute of Finance, Chinese Academy of Social Sciences, also said that blockchain will make it possible for all individuals to become important nodes in the allocation of financial resources, and will also promote the improvement of existing financial system rules. Build a shared and win-win financial development ecosystem.
Blockchain technology will affect many industries
"Blockchain technology has been widely used in the era of big data." Li Yan said frankly that in addition to the Internet financial field, blockchain technology has been used in many industries. It has been applied in many fields and has shown great prospects.
For example, the healthcare industry has benefited greatly from blockchain technology. In reality, patient private information leaks often occur, and centralized database or file cabinet management in medical departments is no longer the optimal choice. Medical institutions are using blockchain technology to keep patients' private information confidential.
In addition, blockchain technology also has important legal implications. In some civil fields, it is often necessary to provide evidence to determine blame, and blockchain technology can record every step and help judicial authorities identify the specific responsible person.
"Especially in the field of assets, whether it is physical assets such as real estate and cars, or intangible assets such as health and reputation, this technology can be used to complete registration, transactions, and tracking. It can be said that any production and life that lacks trust In all fields, blockchain technology will have its place."
The development of blockchain technology has also brought about changes in the operational concepts of various industries. New technologies and new concepts have promoted new developments in various industries. This The impact of this driving force on society and the promotion of economic activities are also huge. Many new industry phenomena will occur one after another, and the public is also waiting and watching, expecting this brand-new technology to be used by various industries and better benefit all industries.
The so-called blockchain technology, also known as distributed ledger technology, is an Internet database technology. Its characteristicsIt is decentralized, open and transparent, allowing everyone to participate in database records.
Explained in layman’s terms: If the database is assumed to be a ledger, reading and writing the database can be regarded as a bookkeeping behavior. The principle of blockchain technology is to find out the fastest and best bookkeeping within a period of time. This person will keep accounts, and then send this page of information to everyone else in the entire system. This is equivalent to changing all the records in the database and sending them to every other node in the entire network, so blockchain technology is also called a distributed ledger.
What is the core technology of Jinwowo blockchain technology?
Chongqing Jinwowo analyzes the core technologies of blockchain technology as follows:
Distributed ledger technology, asymmetric encryption technology and smart contracts.
The core of the blockchain is that it stores all information in an independent personal computer network, making it a decentralized and distributed structure.
This means that the system is not owned by a controlling company or person, but that everyone can use and run the system.

Hope to adopt
What is blockchain technology?Blockchain has been hyped up like crazy, but you know nothing about it!
Blockchain is a distributed database system participated by different nodes and an open ledger system.
It consists of a series of data blocks or data packets generated according to cryptographic methods, that is, blocks. Each block of data information is automatically timestamped, thus Calculate a data encryption value, that is, a hash value (hash).
Blockchain technology is essentially a distributed accounting technology. It allows everyone to have an instantly synchronized account book in their hands. Every transaction that occurs in the entire network will have thousands of backups and synchronous records. When perpetrators attempt to tamper with ledger data, they must change the ledger in the hands of the majority of people to achieve their goal.
I. 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. Blockchain technology is a myth!
Regarding the definition of blockchain technology, American scholar Melanie Swann in her book "Blockchain:"New Economic Blueprint and Introduction" defines blockchain technology as an open, transparent and decentralized 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, those 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.
Since 2008, various games applying blockchain technology have also become popular, such as development games (Network Letts Dog, 360 Block Cat), mining games (NetEase Planet, Virtual Earth, Gongxinbao), these are attracting everyone to join in the name of blockchain, and of course there are some that are really reliable, which requires everyone to identify them carefully.
The three words "blockchain" were completely ignited during the Spring Festival that just passed, and the limelight overshadowed everything else. Some people said that this is the arrival of a new era, and the past has become classic, and others To say that everything is hype 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 issued a request to NewSeed revealed the latest progress in blockchain applications.
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 during the real-time solidification process. 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. Through the combination of the two, it can provide users with real-time and reliable Confirmation plan.
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.
Through the following limited cases, I hope everyone can understand the actual performance of blockchain technology, thereby stimulating interest in such solutions.
1. Administrative Services
Over the centuries, the roles and responsibilities of public administration have not changed significantly – or rather, what has changed dramatically is actually the scale of the data and the specific ways in which public agencies handle it. Although various digital technologies already exist to help collect and process data, issues such as anonymization, portability, and the immutability of large amounts of data remain unresolved.
Sasha Ivanov, founder, entrepreneur and CEO of the Waves Platform and Vostok projects, said, “What the public administration currently lacks is a more convenient user experience (UX) for using data. To improve the user experience, we should introduce some Seed layer - which acts as a trusted public environment that is transparent and can store data anonymously and immutably."
Governments are working on this through federal initiatives such as the launch of the US Federal Blockchain Initiative. Solutions at the institutional and corporate levels are gradually confronting the existence of such problems. The United States held its first federal government blockchain forum in July 2017, and the U.S. General Services Administration currently has more than 200 related use case repositories. Ivanov explained, “Distributed systems can really help us build such a reliable environment, improve our big data work, and even integrate all emerging technologies – including artificial intelligence and the Internet of Things. In fact, , whenever we face any kind of technology, it always embodies the sum of certain other technologies."
Now, the system supported by the blockchain can actually work - this This view has been unanimously recognized by all experts and has become the most important theoretical basis. In other words, what we need to do next is create more production-ready solutions.
2. Payment services
The government needs to process transactions, many of which involve the exchange of funds with citizens. Blockchain technology has huge potential application value in reducing the cost of fund transfers - including using new blockchain-based cryptocurrencies as intermediate transaction carriers, or using blockchain as a means of fund transfer, etc. Once a perfect solution is discovered, the business opportunities will be endless - especially for those who need to conduct frequent cross-border or Internet transactions.
The Jasper project was developed by the Bank of Canada to help it further think about how central banks and other financial institutions should implement payment operations between different banks based on distributed ledgers. The Bank of Canada has also developed its own digital currency variant, “CAD Coin,” to test the feasibility of using a national currency on top of the blockchain.
This project brings to an interesting conclusion that we should say no to proof-of-work public chain systems. In a paper titled "Project Jasper: Is a Distributed Batch Payment System Feasible?" the author observed that "Proof-of-work systems are not suitable for such large transaction processing systems because they assume that all transactions in the system are There is a need for openness and observability to a certain extent.”
3. Digitization and intellectual property
Governments are responsible for maintaining copyright records and databases. These records prove ownership of intellectual property. The blockchain-based system allows artists, performers and writers of all kinds to time-stamp their works andThis could theoretically detect copyright infringements and even preserve a permanent record of rights. In fact, many governments have already taken important exploratory steps in this direction.
Iran recently announced that it will deploy this technology. "Iran Financial Tribune" quoted Morteza Mousavian as saying that "the Digital Media Department of the Ministry of Culture has reached an agreement with a blockchain company to jointly design a system that can be used to protect online copyrights." He also added that "the relevant procedures will It will soon be released to users in an easy-to-use format."
This work is still in the early exploratory stages, but it offers enterprise customers the possibility of preserving records through replication technology. From a theoretical level, companies can use blockchain solutions to conduct financial accounting and discover errors in real time.
4. Welfare distribution
The government has the responsibility to create a level playing field for citizens. Citizens who are chronically poor or economically disadvantaged certainly need government support and assistance to ensure that they are able to sustain themselves and develop. However, welfare distribution is neither simple nor often straightforward. Problems such as corruption and impersonation have been wreaking havoc on various distribution channels within government schemes.
In China, the National Council of Social Security Fund is conducting early research on how to use blockchain technology to improve the delivery of national benefits to citizens. At the same time, India is also taking action. Andhra Pradesh and Telangana are already using blockchain to support their civilian resource supply systems.
It is said that many companies, including Microsoft, are also considering using the same technology. These solutions, which will touch individual employees and functional roles, are expected to gradually appear in small businesses in the near future.
5. Bidding activities
In order to build public infrastructure or provide related services, the government hopes to achieve economies of scale and competitive gains through bidding as much as possible. However, the bidding process is often not fair or transparent. Public procurement has long been a major scene of rampant corruption around the world. Transparency International noted that “many governments will award project contracts to a certain supplier in the absence of fair competition. This allows companies with greater political resources to improperly win over competitors; or companies in the same industry Bids will be negotiated in advance between companies, ensuring that each company gets a share of the tender. This will significantly increase the cost of delivering services to the public - we have found that corruption issues can increase project costs by 50%."
So, how can blockchain technology solve the bidding problem? According to Ivanov, “Unlike decentralized centralized systems, independent ledgers powered by blockchain will be able to improve bidding or anything else that needs to be tracked. Transparency in financial processesSpend. The intervention of blockchain technology will help track the use of funds and ensure that they are paid out as expected and within the allowed time. ”
Currently, Japan’s Ministry of Interior and Communications has announced a blockchain-based bidding system, which means that in industries with serious collusion problems, small and medium-sized enterprises are expected to usher in a more transparent bidding method and Brighter development prospects.
Although quite a few of the cases mentioned previously are far from finalized, they do provide many possibilities for enterprises and governments. Of course, the key lies in implementation; and we All this should also be viewed with optimism, that is, although blockchain technology is often misunderstood by people, it is and will eventually find a direction in which it can exert its own energy!
In layman's terms, blockchain is like There are more than a dozen beacon towers on the Great Wall. If an enemy comes, they will send out smoke. The other beacon towers will know about it and enter a defensive state together. In technical language, it is a distributed ledger. Each node keeps accounts separately. The failure of a single node will not affect the entire network.
How is this distributed network different from the distributed servers of Google Network? Google Network and others The distributed servers still belong to the Google network and are controlled by their central scheduling algorithm. The distributed nodes in the blockchain do not know each other and have no legal affiliation. If you want to go offline and shut down That's fine, but because of the currency rewards, there will always be people who will start up as new nodes to support this network.
After the popular and technical explanation, I hope You already understand. Then the first application scenario is finance. I put the money in Alipay. If Alipay doesn't recognize it one day, there is nothing you can do. But on the blockchain, it is useless if a node does not recognize it. Because other nodes still have my records. The second one is the contract. Nowadays, contracts are signed on paper, which is easy to forge, but it cannot be forged if it is placed on the blockchain.
There are more application scenarios. It is recommended to check the top 100 digital Huobi online to understand the corresponding projects behind them and become a blockchain expert.
Area Blockchain technology was first used in Bitcoin. Blockchain provides a reliable and credible means of organizing data for cross-subject business scenarios. JD.com is essentially a supply chain company, and blockchain technology will first be used in the supply chain In many scenarios.
Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.
Currently, there are more calls for it. The highest application industry is the financial industry.
The application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to conduct full traceability of some of the products sold. Consumers can trace the purchased products. Products are tracked and traced. NumbersThere are also many blockchain applications in the advertising industry. Since digital advertising traffic fraud 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. The digital advertising application of technology mainly solves the problem of traffic fraud
In the future, as the application of blockchain technology becomes more mature, it will be applied in many industries, creating a new ecological model based on technological trust.
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.
What is blockchain If we use non-technical terms to explain blockchain, 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, so In the Internet, a place where data and information are exploding, having such a place would be like a magical treasure.
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.If you want to trust a common algorithm, you can 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, which can be used when seeing a doctor or planning for your own health in the future. Historical data can be called directly. These data are highly private, and the use of blockchain technology also helps protect patient privacy.
