1. How can individuals make money by playing with the blockchain?

Newbies who don’t have much spare money but want to make something big, just follow the example of Huolian Blockchain Academy. If you pay a few thousand yuan in the community, you can make more than ten times the profit when the market comes; the ones who make the least money only buy Bitcoin and Ethereum, so the risk is small.

2. What is blockchain and how should ordinary people invest in blockchain projects?

Blockchain is a distributed technology. Specifically, it can be composed of technologies under the network. There are currently two directions for ordinary people to invest. One is to invest in stocks of blockchain companies, which has certain risks. Individuals can follow what they are familiar with. The other is to invest in virtual currencies, which is similar to Bitcoin. , but you need to choose an old and reliable platform, one with a longer history and a good reputation. You can look at AEX and Huobi. If you want long-term financial management, you can choose AEX Financial Supermarket

< p>3. Several of my friends are playing with blockchain, is it reliable?

Blockchain is also a relatively new thing, and many people are paying special attention to blockchain. Yes, blockchain can be loved by many people, and it can also gain investment from many people. Many people particularly want to invest in blockchain, and they also hope to get more returns by investing in blockchain.

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 change. 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 may lose all their money.

The above is my opinion.

4. 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. Blockchain technology is 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 network distributed around the world. A database storage system that can operate collaboratively is different from traditional database operations - read and write permissions are in the hands of a company or a centralized authority (centralization characteristics). 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 distributed ledger (database) that connects data blocks in an orderly manner and cryptographically ensures that it cannot be tampered with or forged. 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 advantages of easy portability and storage, low circulation cost,It is convenient, easy to prevent counterfeiting and management, breaks geographical restrictions, and can be better integrated.

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. The core enterprises issue accounts receivable vouchers to their suppliers. After the bills are digitized and uploaded to the chain, they can be uploaded to the supplier Transfer between them, each level of supplier can realize the corresponding amount of financing with the digital bill certificate.

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. Tax department launches blockchain electronic issuanceWith the "Tax Chain" platform for invoicing, the tax department, the invoice issuer, and the payee join the "Tax Chain" network through unique digital identities, truly realizing "instant invoicing upon transaction" and "immediate reimbursement upon invoicing" - invoicing in seconds and reimbursement in minutes. , significantly reducing tax collection and administration costs, and effectively solving problems such as data tampering, over-reporting of one vote, 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 effectively reduce 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, third-party electronic signatures haveTaiwan 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 electronic contracts. They refer to a process, from the conclusion of the contract to the confirmation to the final execution." Jin Hongzhou explained.

From a technical perspective, blockchain is not a brand-new technology, but a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, and smart contracts. Specifically, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner.

Due to its advantages such as "decentralization", "distributed data storage", "traceability", "anti-tampering", and "openness and transparency", blockchain technology can effectively solve data problems. Data authenticity, security and openness issues in the fieldBy establishing a trustworthy data management environment, we can prevent and avoid various data management problems such as data fraud, tampering, and loss, and promote the efficient sharing and application of data. In the process of practice and exploration, the application scope of blockchain technology continues to expand, especially in the field of public resource transactions, and continues to empower public resource transaction management services.

Facilitate transaction data sharing and transaction witnessing

Facilitate transaction data Share

Currently, the data of different trading centers are not interoperable, and the subject information of different trading centers needs to be entered repeatedly. It is difficult to verify the off-site performance provided by the bidders during the bid evaluation process. It is difficult to troubleshoot the same person repeatedly serving as project manager. Issues such as low cost of breach of trust. Establishing a cross-regional subject database based on blockchain can well alleviate the above problems.

The distributed ledger feature based on the blockchain can effectively ensure the real-time or quasi-real-time sharing of data, and can reduce the repeated entry of subject information; the use of blockchain information that cannot be tampered with can ensure the data circulation process on the chain. The authenticity of the bidders in the regional alliance is directly obtained from the on-chain data, making it impossible to hide the fake 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

"Guiding Opinions on Deepening the Integration and Sharing of Public Resource Trading Platforms" ( The State Office Letter [2019] No. 41) pointed out the need to optimize services such as witnessing, venues, information, files, and expert extraction. However, at present, public resource transaction process witnessing is mainly based on manual on-site witnessing, which has limited witnessing intensity, high occupation of human resources, and limited witnessing effect. Due to its centralized characteristics, the traditional digital witness system is prone to data tampering, 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 solidify and store the data generated in each transaction link, and accurately record the data generated through time stamp technology, summary algorithm, and electronic signature technology. Time, content, data source. 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 enterprises

Promote the rationalization of electronic guarantee rates

At present, the electronic bidding deposit guarantee guarantee letter It has been used to some extent in the field of bidding and bidding, and has solved the problem of capital occupation in bidding deposits for bidding companies. 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 sustained profitability, but most small and medium-sized enterprises cannot provide these "proofs" at all. Difficulty and expensive financing have become problems faced by many small and medium-sized enterprises in bidding activities. 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. There is a risk of order and contract fraud under the traditional paper-based modelThe process is risky and cumbersome, and 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 are the economic applications of blockchain?

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. Therefore, in the Internet, a place where data and information are exploding, having such a place will be like a magical treasure land.

What can the blockchain do?

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, please comment and correct them..

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 15.72864 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.

5. There are many people who are making money by exploiting blockchain vulnerabilities. Are they really making money?

Now there are many people who are making money by exploiting blockchain vulnerabilities. Blockchain, I think it is really possible to make money through its loopholes, but our family should choose it through formal channels.

6. Let’s talk about my personal views on the blockchain industry

Why various companies should join the blockchain industry

The development of the blockchain industry< br />
The Blockchain 1.0 era is represented by Bitcoin. This period solved the problem of "decentralized" value transfer such as BTC LTC, etc.

Blockchain The 2.0 era is represented by Ethereum. The smart contracts proposed by Ethereum during this period made the blockchain no longer just a currency field, but also aBlockchain can be applied to all walks of life, and a large number of projects serving all walks of life have emerged during this period

The blockchain 3.0 era is represented by many public chains. During this period, the computing speed of public chains has increased significantly. The rise far exceeded that of Ethereum, so DAPP exploded on a large scale.

To put it simply, if blockchain 2.0 is compared to 4G, then blockchain 3.0 is the 5G era.

What is the actual value of blockchain to traditional industries?

It can be interpreted from the following aspects:

(1) Blockchain Chain is a means of secure data processing.

Blockchain essentially has four indispensable core technologies, namely: distributed storage, consensus mechanism, cryptography principles, and smart contracts. Corresponding to data storage, data processing and updating, data security and data operations,

In order to get rid of various problems of current "centralized" servers, such as: hacker attacks, downtime, and selling user information blockchain Use these four core technologies for data processing so that the data becomes traceable and cannot be tampered with. All information will be recorded on the blockchain at the moment it is written, and subsequent transportation, sales, and supervision will also be completely recorded on the blockchain, and no one can change it without authorization. If a problem occurs in the future, the information at that time can be easily traced back to clarify accountability and compensation. This is why it is called a chain. Based on these characteristics, blockchain is used in areas where information fraud is serious, such as rights confirmation, medical care, and charity.

(2) Blockchain is a brainstorm.

Based on the "decentralized" nature of the blockchain, there is no authority in the blockchain industry, or in other words, every individual is the authority. Therefore, a consensus mechanism is adopted, that is, the "consensus mechanism", based on the voting and trust of the nodes, so that all nodes in the entire system can freely and safely store and update data in the system. Different consensus mechanisms determine the different operating perspectives of the system

(3) The blockchain is a tokenization

Based on the tone of blockchain 1.0 and the idea of ​​​​2.0 , basically all blockchain operations require tokens, and the reward tokens used as bookkeeping become the result of the labor of the miners on the chain. The quality of the token affects the enthusiasm of miners to contribute. Tokens are very similar to stocks, so the quality of the token determines the quality of the company.

Enterprises on the chain

The blockchain is very different from the Internet. Its goal is not to make the company’s products easier to sell (because similar goals have made the Internet Achieved). Instead, some of the information carried by these products or services is placed on new infrastructure to generate new value. In consensus economics, this information is called an entropic asset. Why is it called entropy?There are two reasons for this: first, it is scarce; second, it contributes to the formation of consensus.

Only information that is valuable for creating consensus enters the blockchain, which is a cost-effective thing. The most basic part is traceable product information, but traceable value is not necessary in every industry, and blockchain may not be able to solve the authenticity problem of the underlying assets well. Generally speaking, intangible assets are more suitable for being put on the chain, because the property rights system can be quickly improved by using the feature of “disclosure and confirmation of rights”.

However, one must be extremely cautious when putting physical goods on the chain. If IoT technology is used to achieve authenticity traceability, the legal currency price may be too high and the actual return is too low.

Enterprise on-chain is to carry out blockchain economic transformation of traditional enterprises, allowing them to operate on the chain and become a blockchain economic organization, which is enterprise on-chain. A standard blockchain economic organization is a distributed autonomous organization that replaces the traditional collaboration model by issuing certificates, building consensus, improving productivity, and allowing various stakeholders involved in creating wealth to have the long-term interests of the organization. Co-governance and shared power, the greatest value of enterprises on the chain is to provide new economic development momentum, reduce the production cost of enterprises, and increase the value of enterprise assets. Consumers can purchase tokens to share the development and benefits of enterprises; upstream and downstream companies can also purchase tokens to directly deduct payment for goods or other transactions; after the integration of the industry chain, everyone will jointly supervise the development of enterprises in the industry and maintain the tokens. The stability of the certificate. Today, many companies are beginning to set their sights on enterprise blockchain.

Difficulties in companies getting on the blockchain

1. First time involved in the blockchain industry and lack of information

2. Lack of successful candidates under the new token economic model Enterprise operating model

3. Lack of corresponding talents for new technologies

4. Huge initial investment cost

Faced with such problems, many companies are deterred. To ensure the smooth progress of enterprises on-chain, you can find blockchain industry service providers through BCSeeker. BCSeeker allows providers and customers to find trading partners, seek services, and negotiate business on this platform in a free and open manner. It can be said that it has established a free matching market on the Internet without geographical and time barriers, and the whole process is convenient for both parties. Totally free.

BCSeeker has specially opened up a path for on-chain enterprises. What are you waiting for?

7. What exactly is blockchain and how do ordinary people make money in blockchain?

The popularity of blockchain has caught the public off guard. Nowadays, no one knows about blockchain, but many people do not have a clear understanding of the definition of blockchain.

So, what exactly is blockchain?

For blockchain and bitsBitcoin, most people have this misunderstanding: Bitcoin is the blockchain.

In fact, Bitcoin and blockchain are not the same thing. Blockchain is the underlying technology of Bitcoin, but the first usage scenario after the birth of blockchain is Bitcoin.

I will explain to you what Bitcoin is and what blockchain is. Please move your bench quickly!

What is Bitcoin?

Bitcoin is a digital currency, a peer-to-peer encrypted digital currency. It is not a tangible paper currency such as RMB or US dollars. It is generated by computers through specific mathematical calculations. Also stored in the computer.

Because Bitcoin is just a string of data in a computer, it is also called a "virtual currency" compared to paper currency. To put it simply, you can understand that Bitcoin is just a string of numbers with cash value, similar to Q coins. In other words, Bitcoin has no actual value. Its current value is supported by the faith of currency speculators. If the faith is gone, the value of Bitcoin will collapse.

Bitcoin is magical, what is its magic?

If you want to get Bitcoin, in addition to buying it, you can also mine it. The original Bitcoin is mined!

1) Mining

The first thing that comes to mind for many people is the image of a coal mine:

Mine, absenteeism, dust , black coal, large trucks.

Bitcoin mines are not like this. They only need electricity, network cables, and computers. However, mining this mine is a technical job, and it tests the performance of the computer's CPU and GPU.

2) Transaction

How does a Bitcoin transaction proceed?

Each user has a unique address, which is the Bitcoin "wallet". For every transaction, for example: A pays B a Bitcoin, a Weibo post will be posted publicly in the system saying: "I gave B a Bitcoin @B". These records will be kept as evidence at every terminal of the system. on the chain.

If A wants to go back on his word and tamper with Bitcoin’s transaction history, then every terminal record on the network must be modified. However, this is not easy, because only A whose computing power exceeds the sum of the computing power of all nodes in the system can tamper with transaction records. Obviously, this is unrealistic.

In the transaction process, Bitcoin uses a decentralized accounting method, which is also blockchain technology. Simply put, blockchain is a decentralized distributed ledger database.

What is blockchain?

The blockchain is accompanied byBitcoin was created together with Bitcoin. During the formation process of Bitcoin, blocks were storage units one by one, recording the exchange information of each block node. Blocks are very similar to records in a database. Each time data is written, a block is created. . With the expansion of information exchange, one block continues with another, and the result is called a blockchain.

Blockchain is a distributed ledger technology. Everyone participates in accounting, and everyone has a copy of the ledger information. This account book is not easy to forge and is traceable.

For example:

On a certain day of a certain year, Lao Wang lent Xiao Wang 10,000 yuan. Lao Wang told everyone around him the news , the transfer records were posted on WeChat Moments, and everyone helped them testify to the existence of this transaction.

Lao Wang and Xiao Wang are two nodes. These two nodes generate transaction time, location, person and other information, and they are packaged to form a "block". Lao Wang’s friends are also nodes. These nodes jointly record the transaction status and details (blocks) of the two nodes Lao Wang and Xiao Wang. These blocks are connected to form a chain, forming a decentralized database.

In the past, only both parties knew when Lao Wang and Xiao Wang borrowed money. This was the centralized accounting model. But now everyone knows it and records it in their own ledgers. This is the decentralized accounting model. model.

When one day, Xiao Wang regrets that he did not borrow the money, everyone around him will know their transaction information, so Xiao Wang will not be able to deny it. This is the blockchain Information sharing cannot be tampered with.

How do ordinary people make money by participating in the blockchain?

I have summarized several methods suitable for ordinary people to make money during the blockchain bonus period.

1. Direct investment in blockchain: buy coins or buy some blockchain stocks, but the currency circle is risky, so you must be cautious when buying, and there are many blockchain stocks now. However, there are risks in the stock market, so investment needs to be cautious.

2. Make blockchain self-media: run a WeChat public account or Toutiao account, write articles about blockchain and publish them on it. If you are good, you can also get some good profits.

3. Participate in technology development: In fact, it is very simple, it is to participate in the process of blockchain development. However, this method requires high technical threshold.

4. Blockchain training: Companies that can provide blockchain technology training or knowledge training.

That’s all the relevant knowledge about what blockchain is, I hope it can bring you some help.
