⑴ How to define blockchain and what are the application scenarios of blockchain?
Many people now think that blockchain is a universal technology that can do anything. Make blockchain technology a myth!
Regarding the definition of blockchain technology, American scholar Melanie Swann defined blockchain technology as an open, transparent and decentralized technology in her book "Blockchain: A New Economic Blueprint and Introduction" database.
Definition of Blockchain: Narrow VS Broad
As for the application scenarios of blockchain technology, it is natural to combine the differences between blockchain and other technologies. In terms of system characteristics.
Blockchain technology features include:
Blockchain is a global A database storage system that can be operated collaboratively in various places is different from traditional database operations where read and write permissions are in the hands of a company or a centralized authority (a characteristic of centralization). Blockchain believes that anyone with the ability to set up a server can participate. Nuggets from all over the world have deployed their own servers locally and connected to the blockchain network to become a node in this distributed database storage system; once joined, the node enjoys exactly the same rights as all other nodes and obligations (decentralized, distributed characteristics).
At the same time, people who provide services on the blockchain can perform read and write operations on any node in the system. In the end, all nodes around the world will complete the process again and again according to a certain mechanism. Synchronize in sequence to achieve complete consistency of data in all nodes in the blockchain network.
At the beginning of this year, the term blockchain began to enter everyone’s lives. From national leaders to aunts who dance square dances, everyone knows this term. This term is widely known by Bit Brought by coins.
As we all know, the first few dozen bitcoins could only be exchanged for one pizza. At its peak, it was more than 20,000 US dollars each, which has skyrocketed by more than a thousand times, which has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering into everyone's life, and many people have joined the ranks of currency speculation. I often hear people say that if you buy the right currency a hundred times, a bicycle will become a sports car, and one coin will turn a young model. You can imagine how many of them are involved. Attractive.
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.
Blockchain is a method that connects data blocks in an orderly manner and cryptographically ensures that they cannot be tampered with, Unforgeable distributed ledger (database) technology. In layman's terms, blockchain technology can achieve openness, transparency, non-tampering, non-forgery, and traceability of all data information in the system without the need for third-party endorsement. As an underlying protocol or technical solution, blockchain can effectively solve the problem of trust and realize the free transfer of value. It has broad prospects in the fields of digital currency, financial asset transaction settlement, digital government affairs, and certificate deposit and anti-counterfeiting data services.
Digital currency
After experiencing physical objects, precious metals, banknotes and other forms, digital currency has become the development direction of the digital economy era. Compared with physical currency, digital currency has the characteristics of easy portability and storage, low circulation cost, convenient use, easy anti-counterfeiting and management, breaking geographical restrictions, and better integration.
Bitcoin technically implements an electronic cash system in which both parties to the transaction can directly transfer funds to each other without the need for third-party transfer or arbitration. In June 2019, the Internet giant Facebook also released a white paper on its cryptocurrency Libra. Whether it is Bitcoin or Libra, the underlying technology they rely on is blockchain technology.
my country began the development of central bank digital currency as early as 2014. my country's digital currency DC/EP adopts a two-tier operating system: the central bank does not directly issue digital currency to the public. Instead, the central bank redeems the digital currency to various commercial banks or other legal operating institutions, and then these institutions exchange it for public supply. its use. In early August 2019, the central bank held a video conference on work for the second half of the year. The meeting called for accelerating the pace of research and development of the national legal digital currency.
Financial asset transaction settlement
Blockchain technology naturally has financial attributes, and it is causing disruptive changes in the financial industry. In terms of payment and settlement, under the blockchain distributed ledger system, multiple market participants jointly maintain and synchronize a "general ledger" in real time. Payment, clearing, and settlement that currently take two or three days can be completed in just a few minutes. tasks, reducing the complexity and cost of cross-bank and cross-border transactions. At the same time, the underlying encryption technology of the blockchain ensures that participants cannot tamper with the ledger, ensuring that transaction records are transparent and safe. Regulators can easily track transactions on the chain and quickly locate high-risk capital flows. In terms of securities issuance transactions, traditional stock issuance processes are long, costly and complex. Blockchain technology can weaken the role of underwriting institutions and help all parties establish a fast and accurate information exchange and sharing channel. Issuers handle issuance on their own through smart contracts, and regulatory authorities With unified review and verification, investors can also bypass intermediaries and conduct direct operations. In terms of digital bills and supply chain finance, blockchain technology can effectively solve the financing difficulties of small and medium-sized enterprises. It is difficult for current supply chain finance to benefit small and medium-sized enterprises in the upper reaches of the industrial chain, because they often do not have direct trade relations with core enterprises, and it is difficult for financial institutions to evaluate their credit qualifications. Based on blockchain technology, we can establish a consortium chain network covering core enterprises,Upstream and downstream suppliers, financial institutions, etc., core enterprises issue accounts receivable certificates to their suppliers. The bills can be transferred between suppliers after being digitized on the chain. Each level of supplier can use the digital bill certificate to achieve the corresponding amount of financing. .
Digital Government Affairs
Blockchain can make data run and greatly streamline the service process. The distributed technology of blockchain can allow government departments to concentrate on one chain, and all service processes are delivered to smart contracts. As long as the service personnel pass the identity authentication and electronic signature in one department, the smart contracts can be automatically processed and transferred, and the subsequent steps can be completed in sequence. All approvals and signatures. Blockchain invoice is the earliest application of domestic blockchain technology. The tax department launched the "Tax Chain" platform for blockchain electronic invoices. The tax department, the issuer, and the payee join the "Tax Chain" network through unique digital identities, truly realizing "instant invoicing for transactions" and "instant reimbursement after invoicing" - in seconds Level invoicing and minute-level reimbursement accounting significantly reduce tax collection and management costs, and effectively solve problems such as data tampering, over-reporting of one ticket, and tax evasion. Poverty alleviation is another practical application of blockchain technology. Utilize the characteristics of openness, transparency, traceability, and non-tampering of blockchain technology to achieve transparent use, precise investment, and efficient management of poverty alleviation funds.
Evidence-based anti-counterfeiting
Blockchain can prove the existence of a file or digital content at a specific time through hash timestamps, and it is open, non-tamperable, and traceable. It provides perfect solutions for judicial forensics, identity certification, property rights protection, anti-counterfeiting and traceability, etc. In the field of intellectual property, the digital signature of blockchain technology and on-chain certificates can confirm the rights of text, pictures, audio and video, etc., and create and execute transactions through smart contracts, allowing creators to regain pricing power and preserve data formation in real time. The evidence chain covers the three major scenarios of rights confirmation, transaction and rights protection. In the field of anti-counterfeiting and traceability, blockchain technology can be widely used in various fields such as food and medicine, agricultural products, alcohol, and luxury goods through supply chain tracking.
Data services
Blockchain technology will greatly optimize existing big data applications and play a huge role in data circulation and sharing. In the future, the Internet, artificial intelligence, and the Internet of Things will generate massive amounts of data. The existing centralized data storage (computing model) will face huge challenges. Edge storage (computing) based on blockchain technology is expected to become a future solution. Furthermore, the non-tampering and traceability mechanism of blockchain ensures the authenticity and high quality of data, which becomes the basis for all data applications such as big data, deep learning, and artificial intelligence. Finally, blockchain can realize multi-party collaborative data calculations while protecting data privacy, and is expected to solve the problems of "data monopoly" and "data islands" and realize the value of data circulation. In response to the current blockchain development stage, in order to meet the blockchain development and application needs of general business users, many traditional cloud service providers have begun to deploy their own BaaS ("Blockchain as a Service") solutions. The combination of blockchain and cloud computing will be effectiveReduce enterprise blockchain deployment costs and promote the implementation of blockchain application scenarios. In the future, blockchain technology will also play an important role in many fields such as charity, insurance, energy, logistics, and the Internet of Things.
The three words "blockchain" were completely ignited during the Spring Festival that just passed, and the limelight overshadowed everything else. Some people said that this was the arrival of a new era, and the past It has become a classic, and some people say that it is all hype and is ultimately a bubble.
In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, the third-party electronic signature platform eShanbao revealed the latest progress of blockchain applications to NewSeed.
Currently, blockchain technology is mainly used in e-signing products for certificate deposit and certificate issuance. The application scenarios include copyright protection and online signing. , web page forensics, phone recording, email storage of evidence, etc.
Take the rights protection of online works as an example. Since online rights protection generally adopts the method of collecting evidence after the fact, real-time confirmation of rights is not carried out in the process of evidence generation, so the entire confirmation process is difficult. The copyright process is time-consuming, difficult and costly to obtain evidence, and extremely difficult to prove and trace the source. It cannot meet the characteristics of rapid dissemination and large quantity of online works.
eShanbao's new intellectual property protection solution based on timestamp + blockchain starts from the user's real-name authentication and solidifies the information generated 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 electronicContract refers to a process, from conclusion of contract to confirmation to final execution. "Jin Hongzhou explained.
From a technical perspective, blockchain is not a brand-new technology, but an integration of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, smart contract and other computer technologies. New application model. Specifically, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner.
Due to the characteristics of "decentralization" and "distribution" With advantages such as "automatic data storage", "traceability", "tamper resistance", and "openness and transparency", blockchain technology can effectively solve the problems of data authenticity, security and openness in the data field. A data management environment to prevent and avoid various data management problems such as data fraud, tampering, and loss, and promote efficient sharing and application of data. In the process of practical exploration, the application scope of blockchain technology continues to expand, especially in the field of public resource transactions. Empower public resource transaction management services.
Promote transaction data sharing and transaction witness
p>
Promote transaction data sharing
Currently, the data of different trading centers are not interoperable, and the subject information of different trading centers needs to be entered repeatedly. During the bid evaluation process, it is difficult to verify the off-site performance provided by the bidders, and the same personnel are duplicated. Problems such as difficulty in troubleshooting as a project manager and low cost of breach of trust by transaction entities. Establishing a cross-regional entity database based on blockchain can well alleviate the above problems.
The distributed ledger features based on blockchain can Effectively guaranteeing the real-time or quasi-real-time sharing of data, it can reduce repeated entry operations of subject information; the use of blockchain information that cannot be tampered with can ensure the authenticity of the data flow process on the chain. The performance of bidders in the regional alliance is directly taken from the data on the chain. This makes it impossible to hide false performance. At the same time, the sharing of bidding behavior data through the blockchain provides a data basis for the development of "joint punishment of dishonest enterprises".

Blockchain-based transaction witness
The document "Guiding Opinions on Deepening the Integration and Sharing of Public Resource Trading Platforms" (State Office Letter [2019] No. 41) points out the need to optimize witness, venue, Information, archives, expert extraction and other services. However, at present, public resource transaction process witnessing is mainly based on manual on-site witnessing, which has limited witnessing strength, high occupation of human resources, and limited witnessing effect. Due to its centralized characteristics, the traditional digital witnessing system is easy to collect data afterwards Be tampered with, and the data is easily damaged or lost during the storage and migration process, which has certain flaws in terms of security and usability.
Utilize the distributed, difficult to tamper, and traceable characteristics of the blockchain to verify each transaction The data generated in the link are solidified and stored as evidence, using timestamp technology and summary algorithms., Electronic signature technology accurately records the time, content and data source of data generation. According to the technical characteristics of the blockchain, simple structured data can be directly saved on the blockchain. For unstructured layout files, videos, audio and other large files, the summary information and original files can be saved through the blockchain. Save via a distributed file storage service. When there are disputes or problems in a transaction, the blockchain can provide a set of credible transaction process data and clarify the responsibilities of all parties involved in the transaction. Achieve the goals of risk prevention and control in all aspects, traceability of the entire process, and improvement of all-round services.
Promote the rationalization of electronic guarantee rates
Promote financial services and corporate financing for bidding companies
Promote the rationalization of electronic guarantee rates
At present, electronic bidding deposit guarantee letters have certain applications in the field of bidding, solving the problem of bidding deposit funds for bidding companies. Occupancy issues. However, because financial institutions currently do not have reliable historical bidding behavior data of bidders, they are unable to judge the default risks of different bidders. As a result, the guarantee services charged to bidders adopt fixed rates, which makes a small number of bids with high default risks The cost of personal guarantee is allocated to most bidders with low default risk, which increases the guarantee rates for most bidders to a certain extent.
At present, it is up to the bidder to choose whether to use an electronic letter of guarantee, and the rate is the main choice basis for the bidder. If the bidder performance records are shared through the blockchain and the performance risks of different bidders are analyzed, it will be Different bidders provide different guarantee rates, which not only reduces the risks of financial institutions, but also reduces the use costs of most bidders and promotes the use of bid guarantees. To a certain extent, it can also encourage bidders to abide by their promises and maintain the order of the bidding market. .
Promote financial services for bidding companies
The bidding behavior of bidders is scattered in various trading centers, and the data is simply aggregated In a centralized information system, there is a risk of data tampering (untrustworthy), and valuable bidder transaction behavior data cannot be gathered and shared safely and reliably. Through blockchain technology, bidders from multiple trading centers are gathered, and historical bidding, winning bids, defaults, violations and other behavioral records provide data support for financial institutions to evaluate the bidders' credit in the bidding sub-sector.
Solving the financing problems of successful bidders
Traditional corporate loans mainly evaluate the company's solvency: collateral, audit There are requirements for accurate financial statements and sustainable profitability, but most small and medium-sized enterprises cannot provide these "proofs" at all. Difficulty and expensive financing have become the challenges faced by many small and medium-sized enterprises in bidding activities.The problem. Using the methods of the past will no longer work. To solve the financing difficulties of small and medium-sized enterprises, we can only rely on new technologies and new tools. With the help of the non-tamperable characteristics of blockchain, primary business data from multiple trading centers are gathered, and big data analysis technology is combined to build a portrait of a credible bidder. On the one hand, it improves the risk control level of financial institutions and taps high-quality bidding companies. On the other hand, it lowers the loan threshold for bidding companies and optimizes the service experience.
Drawing on the supply chain finance model, the bidder is a core enterprise with good credit in government departments, national enterprises and institutions, and the winning contract obtained by the winning bidder as a supplier is considered by financial institutions to be a high-quality asset. Apply for a loan from a financial institution. Under the traditional paper-based model, there is a risk of order and contract fraud and the process is cumbersome. Centralized information systems require operators to have strong authority. The distributed ledger and difficult-to-tamper characteristics of the blockchain will help solve the above problems. The contract signing between the tenderer and the bidder and the subsequent financial service links will be realized on the blockchain, which not only solves the problem of data trustworthiness but also reduces the risk of corruption. The entire system relies on a centralized authority.
Through further analysis, we found that credit sales are currently prevalent among domestic enterprises, and the upstream suppliers of the winning bidder have a large funding gap. The credit of the bidder can only be passed to the winning bidder (the winning contract cannot be split or transferred), and the upstream suppliers Business owners are unable to obtain high-quality loans from financial institutions. If the winning contract is converted into a "pass" on the chain, the "pass" can be split, and the winning bidder holding the "pass" can pay part or all of the voucher to the upstream supplier, making it possible to discount and finance. The "tokens" on the chain can be split and transferred from first-level suppliers to second-level (and multi-level) suppliers, thereby allowing core enterprise credit to be transferred to multi-level suppliers. The shortage of funds from suppliers due to credit sales has been solved, improving the business environment; through value transfer through the blockchain, the financing cycle has been greatly shortened; the cost of supplier loans has been reduced, which will help reduce the production costs of raw materials or intermediate products, and ultimately Increase bidders' profit margins and indirectly reduce bidders' costs.
Regarding blockchain, we can imagine a decentralized management model and technical processing method.
Let me give you an example. There are five people in your family, and they have never been able to figure out how to arrange work and handle family relationships.
So, you and your family discuss it together and simply use voting to solve the problem.
Then this way of voting to solve problems can be called the most elementary blockchain.
Decentralization solves problems.
What application scenarios can blockchain have?
In fact, many of our families and many organizations use blockchain management forms every day
However, this kind of blockchain application for organizational relationships cannot produce Economic Value.
What economic benefits can blockchain have?What about applications?
The first type is used for tax deposit certificates, bank transfers, etc.
Make full use of the traceability function of the blockchain so that all records can be retrieved and queried at any time
The second type is applied to enterprise operation and management
Enterprises using blockchain management can better solve the problems of enterprise development and allow enterprises to Able to develop faster and make more money.
Summary: The application scenarios of blockchain include taxation, bank transfers, etc., and can also be applied to business operations.
The characteristics of blockchain are distributed accounting and decentralization, but the ultimate goal is to make people get along more equally. Technology is meaningful only when it serves human values, and technology that meets human value needs will develop. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.
Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.
In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.
At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.
Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.
The most popular application industry at present is the financial industry.
An application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to fully trace the origin of some of the products they sell. Consumers can trace the origin of the purchased products. There are also many blockchain applications in the digital advertising industry. Since 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 blockchain 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 ecosystem based on technological trust. Mode
What is blockchain If you explain blockchain in non-technical terms, 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 is exploding and information is exploding, how can there be such aThe place will be like a magical treasure land.
If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:
Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.
If there are any deficiencies, you are welcome to comment and correct me.
In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.
The two parties involved in the transaction do not need to know who the other party is, nor do they need a third party for trust endorsement. They only need to trust a common algorithm to establish mutual trust and conduct direct transactions.
Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire transaction network has changed from a star structure to a point-to-point P2P structure.
In the future, blockchain will be used in many fields and will have a great impact on human life. . It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.
1. Cloud storage
This is the statistics of current cloud storage on the Internet. In terms of volume, Google has the largest volume, which is 8,000PB. So what if we share the idle data on the Internet?
Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15,728.64 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.
⑵ How to make money with the blockchain? Is it a scam?
It is not a scam. Generally speaking, the blockchain is still in its infancy.During this period, many projects have not yet been implemented. Only by cultivating them step by step while respecting the law of growth can they gradually mature. Technology is neutral, but it is human nature that determines the direction and outcome of technology. How blockchain and digital currency will develop in the future depends on the values and civilization of the controller.
Blockchain can allow you to make money in this industry, but it can also make you bankrupt, so I would like to remind users that they need to be cautious when investing. Don’t let yourself get involved without making money, and the gain outweighs the loss. There are also many blockchain scams. We must also be more vigilant to avoid being deceived and causing unnecessary economic losses.
Expand information
Pre-loan stage
Blockchain technology can first be applied to the logistics supply chain to help banks and other lending institutions more comprehensively and accurately grasp the real main business, transaction background, and financing of small and micro enterprises. Downstream affiliated enterprises, as well as their negotiating position in the supply chain, product sales, rhythm and path of payment, etc., on the one hand, help more light-asset, high-growth high-quality enterprises obtain financing support through transaction bills, logistics documents, etc. On the one hand, it prevents problematic enterprises from falsifying their business background and capital needs to obtain loans.
In addition, blockchain can also be applied to the provident fund interconnection to help banks understand the actual payment status of social security, provident fund, etc. of shareholders, executives, and ordinary employees of borrowing companies, so as to reasonably evaluate the size of the company's personnel and operating conditions, and provide credit and loans. Provide sufficient basis for approval decisions.
Loan stage
Blockchain technology can be applied to corporate loan information review and mortgage and pledge review to help banks improve approval efficiency and ensure approval quality. In the financing process of enterprises, especially small and micro enterprises, they often need to provide contracts and other necessary materials. Paper-based contracts with multiple signatures and seals are not only inefficient, but also have a series of problems such as forgery, alteration, and false signatures, which bring problems to bank approval. Greater counterfeiting, fraud and credit risks.
With the support of blockchain technology, relevant real-name information subjects, orders and ordering processes, electronic contracts, agreement signing processes, subsequent supplementary agreements, and photo materials can be preserved in real time, and all stored certificates cannot be tampered with. Ensure that the bank quickly authenticates and approves, and efficiently resolves disputes when they arise. In addition to traditional real estate, other assets owned by enterprises and business owners, including bank financing and other financial assets, can also be used for transfer and pledge, becoming a qualified basis for credit enhancement that can be accepted by banks, improving the availability and immediacy of corporate credit. .
Post-loan stage
Blockchain technology can be applied to the timely assessment of an enterprise's production and operation status and ability to perform repayments, helping banks to effectively grasp credit risks and adjust post-loan risk control strategies at any time. In the past business practice, banks often neither fully understand the true market value of mortgages and pledges, nor can they well judge the impact of the company's operations in warehousing and exiting on the market value of the remaining mortgages and pledges. The ability to control new loan types such as warehouse receipt pledges is relatively low.
After switching to digital warehouse receipts supported by blockchain technology, the quality, quantity, specifications, andPhotos and other information can be uploaded to the chain in a complete and standardized manner, and authenticity and traceability are fully guaranteed. Banks can technically prevent enterprises and warehousing institutions from falsifying warehouse receipts or inconsistencies between warehouse receipts and warehousing information, ensuring that post-loan management is effective. . In addition, information such as factory buildings and office building leasing of borrowing companies can also be fully shared with banks, upstream and downstream enterprises and other intermediary service agencies through blockchain technology, minimizing the risk of money being lost and other issues such as "people leaving the building empty".
⑶ The most straightforward explanation of blockchain
Blockchain is a technology that can ensure that the data on the chain cannot be tampered with or forged.
Blockchain has five important technical characteristics: decentralization, non-tamperable information, openness and transparency, collective maintenance and reliable database.
Specific explanation of blockchain:
1. Specific explanation of the definition of blockchain
In a narrow sense, blockchain is A chained data structure that combines data blocks in a chronological order and is cryptographically guaranteed to be an untamperable and unforgeable distributed ledger.
Broadly speaking, blockchain is a distributed infrastructure and computing method. It is a security technology used to ensure data transmission and access.
In summary, in summary, the blockchain is equivalent to a disintermediated database, consisting of a series of data blocks. Each of its data blocks contains information about a Bitcoin network transaction, which is used to verify the validity of the information and generate the next block.
2. Blockchain infrastructure
Blockchain consists of six infrastructures: data layer, network layer, consensus layer, incentive layer, contract layer and application layer.
3. Purpose of blockchain
Blockchain is mainly used to solve trust and security issues in transactions.
4. Applications of blockchain in different fields
From a scientific and technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming; from an application perspective From a perspective, blockchain is a distributed shared ledger and database, which is decentralized, cannot be tampered with, leaves traces throughout the process, can be traced, collectively maintained, and is open and transparent.
5. Issues that need attention in blockchain
As an important breakthrough for independent innovation of core technology, the security risk of blockchain is a major shortcoming, and security incidents occur frequently. A wake-up call for the industry. To embrace blockchain, we need to accelerate the exploration and establishment of a security system that adapts to the blockchain technology mechanism.
⑷ What is blockchain
In the simplest terms, blockchain is a distributed ledger.
To understand what this means, we first have to look at its opposite: a centralized ledger. Because blockchain technology starts from finance, nextWe will also use banks as an example below.
The following is our process for using bank debit card transactions:
You can swipe your card to purchase goods in stores.
The merchant sends a statement to your bank for the agreed upon amount.
Your bank will verify that you may have authorized the purchase.
The bank sends the money to the merchant.
Finally, the bank records this information in its ledger.
There’s a lot of technology involved here, but that’s basically it. The last step is important - the bank records all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made.
This ledger is kept, maintained and regulated by the bank. You can read it in your online bank account, but you can't change it. The bank has complete control. If it decides to make a change, there's nothing you can do about it.
Crucially, if hackers were able to access a bank’s ledger, that could cause a lot of problems. They can change the account balance to make it look like certain transactions never occurred, etc.
This is why distributed ledgers are so cool.
Blockchain Network Visualization
If a bank operates on a distributed ledger, each member of the bank will have a copy of the ledger, and whenever any member of the bank When they make a purchase, they tell every other member of the bank.
Each member will validate the transaction and add it to the ledger (the added records are called "blocks"). This has some important benefits, as there is no centralized authority that can manipulate records. Hackers accessing one ledger won't be a big problem because other ledgers can easily verify it.
On the other hand, it requires a lot of work. In short, the second system is blockchain (at least in financial scenarios).
As mentioned above, blockchain is a decentralized list of transactions. If I send Xiao Ming 2 Bitcoins, I send a message to everyone in the network saying "I am sending Xiao Ming 2 Bitcoins" and they all record the transaction.
The future of blockchain, how will it change our lives?
One thing that is important about blockchain is that it is a public resource and no one really owns it because everyone owns it.
Blockchain is not just science fiction. We don’t need to understand the mechanism behind this technology, but you do need to understand that it may completely change our lives in the next 20 years.
This may sound bold, but remember, 20 years ago we were browsing the internet on Netscape, using state-of-the-art Motorola flip phones, buying ourThe first DVD player. At that time, if we imagined that a computer could be held in our hands and that we could buy cars, make payments, and watch movies, it would have been considered a fantasy.
Although the impact of blockchain may not be as obvious as the Internet, nor as tangible as mobile phones, blockchain will effectively solve many worries in daily life. Such as intermediaries cheating people, transaction delays, etc. In our current lives, middlemen are everywhere and we take them for granted as a part of life. If one day these intermediaries cease to exist, you will find that the world will become a different place.
Imagine that by 2040, blockchain may become a mature and widely used technology. When one day you can't live without the blockchain just like you can't live without the Internet now, you will be surprised to find that this decentralized accounting technology has simplified the complexity and become a part of your lifestyle
⑸ Blockchain has become a new pyramid scheme, what exactly is blockchain?
Blockchain is the core supporting technology of digital cryptocurrency systems represented by Bitcoin. The core advantage of blockchain technology is decentralization. By using data encryption, timestamps, distributed consensus and economic incentives, point-to-point transactions, coordination and cooperation based on decentralized credit can be achieved in distributed systems without the need for mutual trust. With the rapid development and popularity of Bitcoin in recent years, this research has become a reality. However, the development of new things must be tortuous, and blockchain has become a new pyramid scheme for people.
The third is programmable: Blockchain technology can provide a flexible script code system, which supports users to create advanced smart contracts, currencies or other decentralized applications. For example, the Ethereum platform provides users with a Turing-complete scripting language to build any smart contract or transaction type that can be precisely defined. Ultimately, it is safe and reliable: blockchain technology uses asymmetric encryption principles to encrypt data. At the same time, with the powerful computing power formed by the consensus algorithm, it can resist external attacks and ensure that blockchain data will not be tampered with or forged. , so it has high security
⑹ Is blockchain a pyramid scheme? Be careful of scammers using new technologies to defraud
Many people are not clear about the name blockchain, and even Others suspected it was a pyramid scheme. So the question is, do you understand the definition of blockchain? Do you think blockchain is a pyramid scheme? Some citizens have reported that some people use blockchain to commit fraud, and some people have been defrauded of a lot of money. So, does this mean that blockchain is unreliable?
Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust", created a reliable "cooperation" mechanism, and has broad application prospects.
It is understood that blockchain is a new technology and is not a disguised MLM. It is just claimed by many MLM organizations as "blockchain". In fact, there is no technology and it is just called "blockchain". It's just a pyramid scheme. The state has issued announcements many times to crack down on this type of pyramid scheme.
However, I hope everyone understands that blockchain is high technology and a new technology that has brought many changes to society. However, in order to make money, scammers set their sights on the blockchain, and their purpose is to use the blockchain to defraud. Therefore, everyone must be careful of similar scams. Before investing in a project, you must investigate to see if it is legitimate and reliable.
I once again remind you that blockchain is just an underlying technology of the Internet and has nothing to do with pyramid schemes. Because many people don’t understand it, many people use the slogan of blockchain to carry out pyramid schemes to illegally raise funds. . In fact, to identify MLM, you need to look at three characteristics:
1. Entry fee. Whether it is necessary to subscribe for goods or pay fees to obtain the qualifications to join or to develop the qualifications of others to join to obtain illegal benefits; 2. Pulling people. Whether it is necessary to develop others to become one's downline, and pay the personnel developed based on the number of people they develop directly or indirectly on a rolling basis to seek illegal benefits; 3. Remuneration method. Whether remuneration is calculated based on the sales performance of direct or indirect development personnel to seek illegal benefits. If it meets the above characteristics, it may be suspected of pyramid schemes.
⑺ What are the characteristics of blockchain?
Characteristics of blockchain: 1. Security: not subject to attack by any person or entity; 2. No information can be tampered with; 3. Traceable, All nodes in the network are accessible; 4. Decentralized, no third party. Regarding blockchain news, you can learn about it at Crypto Finance.
⑻ What exactly is blockchain? Which blockchains have physical applications
What is blockchain?
Official definition: 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.
Vernacular understanding: A block is to package all the data generated within a time period in chronological order. Generally, the length of a block is 10 minutes, which means that within 10 minutes, all the data on the Internet will The data is packed into a complete package, and this complete data package is called a block. The blockchain links these data packages in order to form a structure, and cryptographically ensures that it cannot be tampered with or forged to form a distribution. ledger, this is the blockchain.
It seems that everyone has a preliminary knowledge and understanding of the blockchain. So whether the blockchain has any practical application in daily life, the answer is yes, the current practical application There are mainly the following aspects. Of course, I may not know some of them. Friends are welcome to leave messages to add.
Financial Industry
Blockchain should be used the most in the financial industry.
For example, in May 2017, OMG (Omise Coin) announced that it would cooperate with Alipay to launch an electronic wallet, integrating the "Alipay" payment solution into its own payment service suite to help local electronics in Thailand. Business merchants accept online payment transactions from Chinese tourists.
Another example is PPT, which is a financial transaction system for bills based on blockchain.
Gaming
The gambling industry entered the blockchain probably last year. Why does gambling favor blockchain? Because blockchain provides a relatively fair betting system. Why? It is relatively fair. As can be seen from the previous introduction, the blockchain cannot be tampered with or forged.
For example, WICC (WikiChain) can realize rich application scenarios such as asset issuance, betting applications, copyright traceability, mutual insurance, decentralized exchanges, and cross-border settlement.
For example, the STX (King of Fighters Token) stox application is designed to provide the full functionality of a prediction market application without the need for any central server. Prediction markets require functions such as event planning, market production, providing information and analysis to traders, reporting event results, and of course collection and payment.
I believe that if the current lottery industry is built on the blockchain, people will become more and more enthusiastic about buying, because there are too many insider tips that make people give up.
Internet of Things
The Internet of Things still has many applications on the blockchain, because the traceability and immediacy of blocks are very suitable for this industry.
For example, DATA is the concept of the Internet of Things. It is a decentralized p2p network. Data sources can connect to any node in the entire network, then publish data, and the network will immediately send it to subscribers. Horizontal scalability is achieved through sharding pattern. This timeliness and accuracy are very important in IoT applications.
Game industry
For example, GTC (G coin) is a decentralized digital asset based on Ethereum erc20 issued by Game Global. G coin is committed to becoming a universal number in the global game industry. Monetary standards.
For example, MANA is a distributed shared virtual platform. On this platform, users can browse and discover content and interact with other people and entities. Users can also claim ownership of virtual territories through a blockchain-based land ledger. The territory is demarcated by rectangular coordinates (x, y), and its owner can decide the content published on the territory, including static 3D scenes to interactive systems such as games.
There are many other industries. The emperor did not list them one by one, but listed a few representative ones. What is the purpose? It shows that the blockchain is definitely not just a currency transaction, it is a real implementation project, and it is a product of the changes of the times with real practical uses.
The development of human society is actually like the Blockchain chain. Is itIt is reversible and unstoppable. As far as I feel, sooner or later, blockchain will enter thousands of households. No matter whether it is bull or bear, hold on to the value coins in your hands. Flush has started to quote digital currency, which shows that society is accepting it step by step. Social development The power of China cannot be stopped by any country or person.
⑼ Is blockchain a pyramid scheme? Is blockchain a disguised pyramid scheme?
Blockchain is a new technology and is not a disguised pyramid scheme. It is just claimed by many pyramid schemes to be "blockchain "Chain" actually does not have any technology, it is just a pyramid scheme in the name of "blockchain". The country has issued multiple announcements to crack down on this type of pyramid scheme. The following is Xinhuanet's report on blockchain MLM:
Blockchain is not equivalent to virtual currency, and there are also security risks. Behind the popularity, there are exaggerated publicity campaigns with "ulterior motives". Only by removing the flashiness can the blockchain return to its true application value.
Invest 80,000 yuan and it will become 800,000 yuan in three months? Shenzhen police uncovered a huge fund-raising fraud case. Under the guise of blockchain concepts and 10 times earnings, thousands of investors have fallen into it, with the amount involved reaching 307 million yuan. Under the "mysterious veil" of the blockchain, criminals have taken advantage of the opportunity to use their tricks, and the blockchain has become a "signature" for economic crimes such as fraud and pyramid schemes.
Why has the blockchain been repeatedly “misused” by illegal activities such as pyramid schemes and fraud? Apart from being “unclear”, what is the “function” of blockchain technology itself? Since the beginning of this year, with the intensification of supervision and the cooling of the trend of currency speculation, new opportunities have been brought to the development of blockchain. How is the implementation of blockchain commercial "applications" now? Reporters from "Lookout" News Weekly recently conducted an investigation into this.
When the three-month "fund release period" promised by the trading platform expired and the staff started "kicking" people in the QQ group, Tang Haiyan, who lives in Bao'an District, Shenzhen, realized that she might have been cheated. .
Previously, Tang Haiyan invested 80,000 yuan to buy a virtual currency called "Puyin Coin" under the introduction of a classmate. "The other party said that this currency is the most advanced blockchain technology at the moment, with Tibetan tea as collateral, and he also showed me a 'technical white paper'. I didn't understand blockchain, so I didn't read it carefully."
Although he doesn’t know much about blockchain or virtual currencies, Tang Haiyan is full of expectations for the high investment returns. She told reporters that the company that issued the "Common Silver Coin" would regularly split the virtual currency at a ratio of 1:10, which means that each split would increase the value of the "Common Silver Coin" in the hands of investors by 10 times. . As long as it is split once, the 80,000 yuan she invested is equivalent to buying "common silver coins" worth 800,000 yuan, and she can get huge profits by selling them on the trading platform.
According to the rules of the trading platform, the "common silver coins" just purchased cannot be traded immediately. They must be frozen on the platform for three months before the "release period" can begin. However, when three months passed, Tang Haiyan not only failed to double her assets, but also the 80,000 yuan frozen on the platform could no longer be used for transactions.
"OtherInvestors began to question the authenticity of this investment in the QQ group. As a result, the company staff kicked these investors out one by one, which made me feel bad. ” she said.
Facts also proved Tang Haiyan’s intuition. At the end of March 2018, the Shenzhen police detected a huge fund-raising fraud case, with the defrauded funds reaching 307 million yuan. In this case, the Shenzhen general public involved Yin Blockchain Group Co., Ltd. uses the "blockchain + Tibetan Tea" model to issue virtual currency and rob public deposits. Tang Haiyan is one of thousands of victims.
Shenzhen Police The investigation found that the company claimed that investors could buy and sell "Puyin Coins" on the virtual trading platform "Jubi.com" to earn the price difference
. In fact, the change in its buying and selling price was The company used investors' investment funds for behind-the-scenes operations, and once raised the price of "Puyin Coin" from 0.5 yuan to 10 yuan, allowing investors to taste some sweetness. When a large number of investors entered the market, the company used malicious Manipulating the price trend of "common silver coins" to continuously cash out will eventually lead to the "common silver coins" in the hands of investors being worthless.
Since 2018, engaging in fraud and pyramid schemes under the banner of blockchain has become a "Routines" commonly used in new criminal methods. In April 2018, Jinan police shut down a pyramid scheme gang under the guise of "western development", "national poverty alleviation", "original stocks", "blockchain" and "e-commerce". More than ten main suspects were arrested, more than a hundred accounts involved were frozen, and more than 300 million yuan of funds involved were seized.
Jinan police introduced that Huileyi E-commerce Company used the reason that the country is vigorously developing the big data industry. , designed fake virtual disks on the Internet, and released various virtual currencies such as so-called "treasure coins" and "precious coins".
They first used gifts as a guise to give gifts to newly joined MLM personnel. A certain amount of virtual currency, each priced at tens of yuan, is then artificially manipulated to increase the value of the virtual currency to more than 100 yuan or even hundreds of yuan, attracting people who do not know the truth to join, and finally fluctuates through the so-called "depreciation" cycle of virtual currency. Carry out "cutting leeks" over and over again, and finally achieve the purpose of making illegal profits.
In Xi'an, the local police also successfully cracked a huge online pyramid scheme under the banner of blockchain. According to the police, The criminal suspect Zheng paid a high salary to organize network platform administrators Zhang, Li and other 9 people. Since March 28, 2018, he has used collective pyramid schemes and online pyramid schemes to sell coins in the "Consumption Era" at a price of 3 yuan each. "The online platform sells virtual "Datang Coins" and controls the appreciation rate;
At the same time, promotion meetings are held in many cities at home and abroad to attract members, and 28-level agents are set up according to the development and offline status of members. , in just 18 days, the group has developed a total of more than 13,000 registered members. It has been found that the case involves 31 provinces, municipalities, and autonomous regions across the country, and the funds involved are as high as 86 million yuan.
Tencent Security Joint Laboratory released "Tencent's 2017 MLM Situation Awareness White Paper""Book" stated that in recent times, various overseas capital disks, virtual currencies, and ICO (blockchain project initial public offering token financing) projects have emerged one after another, which hide illegal issuance, false projects, cross-border money laundering, and fraud. , pyramid schemes and many other risks, causing a large amount of funds to flow overseas. Once they collapse, run away or lose contact, investors often have no way to complain and their losses are difficult to recover. For example, Baichuan Coin, Mark Coin, Beta Coin, Dark Coin, etc.
Reporters from "Lookout" News Weekly conducted interviews in Guangdong, Shandong, Shanghai and other places and learned that most people know that the concept of blockchain is very popular, but they are "uninformed" about the specific functions of blockchain. There are different opinions: some people think it is used for "investment and financial management" and "buying and selling currency", while others think it is "a major invention of the same magnitude as the steam engine". Some entrepreneurs are gearing up to seize this "once-in-a-lifetime opportunity to get rich."
Many people in the industry said that it is precisely because people have many misunderstandings about blockchain that criminals have the opportunity to fish in troubled waters and mislead investors.
First, blockchain is not equal to virtual currency. As of the end of last year, the number of domestic ICO participants and total transaction volume had doubled. A large number of digital currency exchanges have fled overseas, and the agency investment model has involved more ordinary people in high-risk investments.
Many industry self-media and famous speakers have formed interest alliances with issuers, digital exchanges, etc. to endorse the "Air Coin" project platform and create public opinion. In December last year, the People's Bank of China and nine other departments characterized ICOs as "suspected of illegal fund-raising, financial fraud, pyramid schemes and other illegal and criminal activities."
During the interview, many people told our reporter that the existence of tokens has built a set of equity mechanisms for the development of blockchain technology. This mechanism is indispensable for stimulating the prosperity of blockchain applications. of. "Market practice in the past five years has proven that blockchain applications without equity mechanisms are like computers without Internet connectivity and a market economy without currency. The application scenarios and development speed are greatly reduced." said an investor in Shanghai. .
In fact, tokens represented by Bitcoin are only one of the earliest products to verify blockchain technology. There is no equivalence between the two, and the existence of tokens has already affected the blockchain technology. The development of the chain has obvious negative effects.
At present, more and more people in the industry are beginning to think about whether the development of blockchain must rely on the issuance of tokens to achieve incentives. Guo Dagang, secretary-general of the Beijing Internet Finance Industry Association, told this reporter that the so-called incentive mechanism is just a theoretical basis for project parties to issue tokens.
Secondly, blockchain is not omnipotent and there are risks in its security. Blockchain is generally considered to be able to achieve three functions:
First, the data stored on the blockchain cannot be tampered with or forged, and the data has high credibility and credibility; second, The entire transaction process is traceable, enabling accurate tracking of responsibilities; third, smart contracts embedded in the blockchain can be automatically executed based on the contract, thereby improving work efficiency and reducing the risk of default. IndustryIt is generally believed that blockchain has broad application prospects in finance, logistics, trade and other fields.
In fact, blockchain is not omnipotent, and its functions also have many limitations. It is generally believed that based on its cryptographic characteristics, if you want to tamper or forge on the blockchain, you theoretically need to control more than 51% of the nodes to achieve it. When there are enough nodes in the blockchain, this trust creation mechanism with widespread public participation will be difficult to tamper with.
However, in reality, digital currency exchanges are frequently attacked or even stolen. On June 20, 2018, South Korea's Bithumb exchange announced on its official website that the exchange was attacked by hackers and cryptocurrency worth 35 billion won, or approximately US$32 million, was stolen.
Ji Xinhua, known as China's first generation "hacker", said that the blockchain will continue to face attacks, and the process of uploading data to the chain is prone to information leakage. Some people in the industry are also worried that once the super computing power of quantum computing is realized, it will also have a direct impact on the blockchain.
Thirdly, the popularity of blockchain is not entirely true. Data shows that from the end of 2017 to the beginning of 2018, more than 300 self-media companies mainly focused on ICO projects appeared, which became an abnormal phenomenon worth noting.
On August 24, 2018, the China Banking and Insurance Regulatory Commission website issued a risk warning, reminding The general public is advised to guard against illegal fund-raising in the name of “virtual currency” and “blockchain”.
The original text is as follows:
"Risk Tips on Preventing Illegal Fund-raising in the Name of "Virtual Currency" and "Blockchain""
China Banking and Insurance Regulatory Commission, Central Network The Office of Information Technology, the Ministry of Public Security, the People's Bank of China, and the State Administration for Market Regulation remind:
Recently, some criminals have issued so-called "virtual currencies" and "virtual assets" under the banner of "financial innovation" and "blockchain". ""Digital assets" and other methods absorb funds and infringe on the legitimate rights and interests of the public. Such activities are not really based on blockchain technology, but are actually hyping up the blockchain concept to conduct illegal fund-raising, pyramid schemes, and fraud. They mainly have the following characteristics:
1. Networking and cross-borderization are obvious. Relying on the Internet and chat tools for transactions, and using online payment tools to receive and disburse funds, risks have a wide scope and spread quickly. Some criminals rent overseas servers to build websites, essentially carry out activities for domestic residents, and remotely control illegal activities.
Some individuals claim in chat tool groups that they have obtained investment quotas for high-quality overseas blockchain projects and can invest on their behalf, which is most likely a fraudulent activity. Most of the funds for these illegal activities flow overseas, making supervision and tracking very difficult.
2. Strong deception, temptation and concealment. They use hot concepts to create hype and fabricate numerous "high-level" theories. Some even use celebrity V's "platform" propaganda, and use airdrops of "candy" as temptations, claiming that "currency values only rise but not fall" and "the investment cycle is short. High income", low risk" and highly deceptive.
In actual operations, criminals illegally make huge profits by manipulating the price trend of so-called virtual currencies behind the scenes and setting profit and withdrawal thresholds. In addition, some criminals make huge profits illegally. Tokens are also issued under innovative names such as ICO, IFO, and IEO, or virtual currencies are speculated in the form of IMO under the banner of the sharing economy, which is highly concealed and deceptive.
3. There are various illegal risks. Through publicity, criminals use "static returns" (profits from currency appreciation) and "dynamic returns" (profits from offline development) as bait to attract the public to invest funds and lure investors to develop personnel. Join and continuously expand the capital pool, which has the characteristics of illegal fund-raising, pyramid schemes, fraud and other illegal activities.
Such activities use "financial innovation" as a gimmick, and are essentially a Ponzi scheme of "borrowing new to repay old". It is difficult to maintain the operation of funds for a long time. The general public is requested to view the blockchain rationally, do not blindly believe in the promises made by the sky, establish correct currency concepts and investment concepts, and effectively improve risk awareness; for any clues about illegal crimes discovered, they can actively report to the relevant departments. .
⑽ What is the mystery of blockchain technology and what impact will it have on people’s production and life?
Bitcoin was invented in late 2008 and early 2009. Virtual currency, he published an article "Bitcoin: A Peer-to-Peer Electronic Cash System". Blockchain technology is a technology he used. In other words, Bitcoin is the world's first "decentralized In order to invent it, Satoshi Nakamoto created a new technology and named it "blockchain". In 2019, in collective learning, the country highly emphasized the need to accelerate the development of blockchain technology and industry . One of the important characteristics of blockchain is that it is decentralized, cannot be tampered with, and cannot be forged.
Blockchain technology will definitely have great achievements in the future. Now it is a new technology, and the public may not be familiar with it. The acceptance is not high. However, with the support of national policies, the advantages of blockchain technology have become more prominent, and the fields of application will be more extensive in the future.
