1. What is blockchain and what role does blockchain play

What is blockchain? What changes will it bring to your future life?

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms.

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of related cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

In the original English version of the Bitcoin white paper, the word blockchain does not actually appear, but chain of blocks is used. In the earliest Chinese translation of the Bitcoin white paper, chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.

The Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations" on January 10, 2019, which will come into effect on February 15, 2019.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and Unforgeable distributed ledger.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and Access security, a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data.

In fact, to understand it very simply and vividly, we can imagine that everything in life is realized in digital form, including food, clothing, housing, transportation, medical treatment, education, etc., based on the Internet, it can be easily done at home Get it done, no matter where you go to do business or trade, you can completely operate it with your mobile phone. With the continuous development, everything we do can be easily completed online, such as volumetric work, production, planting, etc. Of course, the rise of 5g will bring about the end No one can accurately predict what it is now, but it will definitely bring about earth-shaking changes in life and social form!

Blockchain was born from Satoshi Nakamoto’s Bitcoin. Since 2009, various Bitcoin-like digital currencies have appeared, all based on public blockchains.

The current situation of digital currencies is that a hundred flowers are blooming. List some common ones: bitcoin, litecoin, dogecoin, OKcoiIn addition to currency applications, netc also has various derivative applications, such as NXT, SIA, BitShares, MaidSafe, Ripple, Ethereum, etc.

On January 20, 2016, the People’s Bank of China Digital Currency Seminar announced that it had achieved phased results in digital currency research. The meeting affirmed the value of digital currency in reducing the issuance of traditional currency and stated that the central bank is exploring the issuance of digital currency.

Some areas where blockchain can be used can be:

▪ Smart contracts

▪ Securities trading

▪ E-commerce

▪ Internet of Things

▪ Social communication

▪ File storage

▪ Proof of existence

▪ Identity verification

▪ Equity crowdfunding

The development of blockchain can be compared to the development of the Internet itself. In the future, there will be an Internet called finance-internet, and this thing is based on blockchain, its precursor is bitcoin, that is, traditional finance starts from private chains and industry chains (local area network), and the bitcoin series starts from public chains (wide area network), both expressing the same The concept of digital assets (Digital Asset) eventually converges to an intermediate equilibrium point.

The core advantages of the blockchain architecture include:

Any node can create a transaction, and after a period of confirmation, it can reasonably confirm whether the transaction is Effectively, blockchain can effectively prevent problems from happening on both sides. The cost of trying to rewrite or modify transaction records is very high. Blockchain implements two types of records: transactions and blocks. Transactions are the actual data stored on the blockchain, while blocks are records confirming when and in what order certain transactions became part of the blockchain database. Transactions are created by participants using the system in the normal course (in the case of cryptocurrencies, a transaction is created by Bob sending tokens to Alice), while blocks are created by what we call Units of miners are responsible for creation.

So in conclusion, this is undoubtedly a new technology that changes life. In the future, the production activities of the entire society will use blockchain as the underlying logic.As the series unfolds, we can put many things at our fingertips. Coupled with the integration of artificial intelligence and big data, we can easily handle things that seem to be complicated now, such as some securities market transactions and the intelligentization of financial management activities. match.

To put it simply, blockchain is a network computing center that integrates people, property, machines, and goods, and packages it into a whole; putting it on an infrastructure to run the network computing center .

Now the author’s imagination is not big enough to imagine what the future world will be like. I am looking forward to it!

I know a thing or two about this issue. Let’s get to know this mysterious thing - blockchain.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each The data block contains information about a batch of Bitcoin network transactions, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block

The more popular it is, the more fake it is to keep the real. First of all, we must first figure out what the real blockchain technology is.

As an example, take buying fruits online.

The process of purchasing fruits online is as follows:

Using blockchain technology and decentralization, the process of purchasing fruits is as follows:

Summary:

1. We found that the original transaction process is: buyers and sellers make transactions, and all key processes are dealing with the payment platform. The advantage of this is that if there is a problem in any link, both sellers and buyers can seek help through the platform and let the platform arbitrate. However, a major bug or hacker attack occurs on the platform, resulting in the loss of all transfer records within a period of time. How to deal with the loss is a troublesome matter.

2. The transaction process using blockchain technology is: everyone’s ledger has exactly the same transaction record. Even if Alipay’s ledger server is broken, the seller’s ledger still exists, and the buyer’s ledger still exists. Still exists. Once this transaction occurs, the traces will never be erased.

This is the core of the blockchain, which is the four words "accounting + accounting".

The development and maturity of blockchain technology cannot be separated from the foundation and foreshadowing of the above new generation of Internet technology. Blockchain is not only a technology, but also provides a service model and solution. , which has played an extremely important role in promoting the further development of the Internet industry.

1. Blockchain + Finance

2. Blockchain + Supply Chain Management

3. Blockchain + Intelligent Manufacturing

4. Blockchain + Public Services

5. Blockchain + Education and Employment

6. Blockchain + Culture and Entertainment

7. Blockchain Chain + Payment

8. Blockchain + Invoice {Already enabled in Shenzhen}

The traceability and non-tamperability of blockchain are innate with the nature and needs of the financial industry , just combined together, this makes the application of blockchain in the field of financial services the most in-depth and relatively mature field so far. Blockchain technology has broad application prospects. The future technological competition will also be a blockchain competition.

It is important to understand blockchain, which is important to see through various pseudo-blockchain scams.

If someone uses a bunch of professional terms to explain blockchain, it will be difficult for you to understand, and they may not really understand it themselves.

Therefore, we first establish a psychological line of defense. Anyone who sells you concepts and uses a lot of unfamiliar technical terms may be a liar. Be very careful!

To understand blockchain, you must know what the core appeal of blockchain is. What do you think you are most worried about in today's highly developed Internet world?

Privacy, yes, privacy. How to protect privacy? You may be monitored at any time, and any of your personal information may be stolen at any time. If personal privacy is not absolutely protected, the Internet will become another pyramid of power. Who is standing on top of the pyramid? He is the smartest technical master, a platform provider, and an information regulator. You and I may be the people at the bottom of this pyramid.

The people who originally invented the blockchain had serious concerns about being completely swallowed up by the Internet, and tried to create an absolutely safe encryption technology to lock up personal privacy. This technology completely subverts traditional encryption technology. In fact, rather than locking up privacy, it is better to tear it into pieces and then distribute the pieces to different people for private keeping. Unless everyone agrees to take the pieces and piece together the complete code, the truth cannot be recreated. This is the first mechanism of blockchain, which is decentralization.

But decentralization alone is not enough. It is also necessary to make those who steal password fragments have nowhere to hide, so that every action of the thief can be recorded indelibly and posted everywhere on the Internet. Diffuse and make it public. This is the second mechanism of the blockchain, the non-anonymous mechanism. Do you think, who snoops into privacy is not sneaky?

To sum up, the blockchain is to hide privacy in a decentralized manner.Come, record and make public any actions that recreate this privacy. Seeing this, you may want to applaud the blockchain. Don't worry, how can there be such a good thing in the world? Is there any utopia that is absolutely safe? If blockchain can be realized in an absolute sense, will the existence of the government still be meaningful? Yes, blockchain was originally the embodiment of anarchy. Its ultimate meaning is destined to never be realized. Its survival may have to rely on power, and it is destined to become another beautifully packaged lie and a pretense to deceive people. In this sense, the government must also specify a framework for the development of the blockchain, reconstruct the value of the blockchain, and expel the anti-government and anti-national attempts contained in the blockchain. Some blockchain technologies can be used in concrete applications, but decentralization must not be promoted. In short, we must remain highly vigilant about blockchain. Beauty often hides its sting. Absolutely ideal recipes often turn out to be poison. The person who says he can absolutely protect your privacy and financial security is the real voyeur and vampire.

Perhaps the best way for us to protect privacy is not to have any privacy, to live a completely open life, either to live like a sun or to live like a god of wine.

Viewpoint: 1. The concept of blockchain originated from the technical attributes of Bitcoin (distributed data storage and accounting, decentralization, inability to tamper with transaction records, point-to-point information transmission, sharing mechanism...), but Later, some people continued to extend and expand the concept to many commercial fields to facilitate capital speculation. 2. Blockchain in reality (the current blockchain on the market is very confusing), the hype concept is mostly used to make money in the stock market, and there is still a lack of regulatory loopholes. , legal and regulatory issues, etc., and even money laundering (the actual operation of blockchain products is one thing, the capital operation behind it is another). At present, the computer systems around the world cannot meet the characteristics of blockchain attributes. Technical requirements (such as distributed data storage and accounting, decentralization...), network bandwidth, storage technology and computer computing systems cannot meet transaction operation requirements (it is easy to use computer technology to make your network clogged or unable to complete distribution) There are risks arising from practical applications such as formal data storage or transactions being interrupted or delayed at any time. In addition, as far as the current global computer system is concerned, it is easy to crack the underlying program of the blockchain (this is a fatal flaw in the current global computers, 0 and 1 binary logic In addition, if the reverse blockchain mode calculation algorithm is used, it is very easy to crack the blockchain. This reverse calculation mode can also completely tamper with all transaction records. If a true quantum computer becomes available in the future, it can directly break all blockchain computers in seconds. System, Bitcoin mining is a Ponzi scheme, 3. Most of the blockchains currently on the global market are basically capital speculation concepts to make money.

The concept of blockchain has been around for several years. , I heard a blockchain boss say at the beginning of last year that 2018 is the best year for the development of blockchain. After this year, foreign development will fall behind. What is blockchain? In terms of impact, it is like a pig. The large intestine is connected section by section.Blockchain is to connect these blocks together, fix them, and use computer and Internet encryption technology to prevent secrets from being leaked to the outside world. This technology cannot be explained to non-professionals through professional terminology, and generally they will not understand it. It can only be explained with an analogy. Let me give you two examples:

1. Four people, A, B, C and D, play mahjong and gamble in a mahjong parlor. They use chips for each game and settle the bill at once when they break up. A loses 1,500 yuan and B loses 300 yuan. Yuan, C won 200, and D won 1,600. As a result, A only has 1,000 yuan, and everyone else has sorted it out, but A still owes D 400 yuan. Only these four people know about this matter, and these four people are one block. There is no proof for what he says, and he doesn’t know how to write an IOU for this kind of thing. What will happen if A doesn’t pay back the money in the future? Except for the four people A, B, C and D who were present, no one else knew about this matter. If A wanted to default on the debt and said that he did not owe money at all, only three people, B, B, D and D, knew that A was defaulting on the debt. It would be difficult for others to judge whether A owed money and refused to pay it back. Therefore, the value of blockchain needs to expand participation. What if these four people were playing mahjong and a dozen friends were watching? Isn’t the cost of defaulting on the loan high? This is real life block. What about extending to the Internet? Then there are endless possibilities and there are many scenarios.

2. If four people, A, B, C and D, do business in a business group of 500 people, this group of 500 people is a big block. Once, A asked B for 10,000 yuan of goods, but did not pay B in time. A said at that time that he would pay B within 3 days. Everyone in the group knows this. If A fails to send money to B within 3 days, then the other 498 business partners in the group will know about it. If A defaults on the debt, his reputation in this business circle will be ruined. affected. This is a block.

Later, A wanted to do business with C. C asked A for goods. A said, you pay a deposit of 5,000 yuan and the goods will be shipped immediately. C paid 5,000 yuan to A, but A was delayed. Not shipping, everyone in the group knows this, this is another block. When the two blocks are connected, everyone doubts A's credibility. How many times have you done this? Will Mr. A continue to play in the future? This is the value of blockchain.

Blockchain may seem complicated, but it is not complicated at all; it may seem simple, but it is actually very difficult to operate. The blocks are too small and meaningless. If a block wants to grow bigger, privacy and business secrets will be involved. For example, it is inconvenient to talk about falling in love in a large group; for example, it is inconvenient to discuss it openly in the group (block) beforehand when working together to do big business. However, there are still occasions when blockchain technology is used, such as poverty alleviation work, disaster relief fund management, etc. It is exposed to the sun and everyone knows it and supervises each other. I’ve given these two examples. Do you understand them at all?

[The most core and easy-to-understand introduction to blockchain]

1. How does blockchain create trust? We use “1”, “2” and “3” to summarize the areasCharacteristics of blockchain:

- "1" summarizes blockchain in one sentence: a trusted distributed database;

- "2" core properties: distributed, Cannot be tampered with;

- "3" key mechanisms: cryptography principles, data storage structure, and consensus mechanism.

The "distributed" and "non-tamperable" properties ensure the "honesty" and "transparency" of the blockchain, which is the basis for the blockchain to create trust.

2. In terms of industry, it is expected that the financial industry will be dominated by the financial industry in the next 3-5 years, gradually radiating to other real industries, more realistic scenarios will be accelerated, and the industry will develop from "1 to N" to Including entertainment, product traceability, credit reporting, etc.

In the future, in addition to using technologies such as side chains, lightning networks, and cross-chains, blockchain will also need to be deeply integrated with emerging information technologies such as 5G, artificial intelligence, big data, and the Internet of Things to enhance the Technical performance and off-chain data quality and reduce resource waste.

3. Smart contracts may be the most revolutionary application on the blockchain. If smart contracts are widely used on the blockchain, the economic division of labor will be further refined in the Internet era. Network nodes around the world will directly connect demand and production, and broader social collaboration will be realized.

If the above vision is realized, the combination of blockchain technology and industry is expected to usher in an explosive moment "from 1 to N". Its explosion may not be linear but non-linear. Blockchain Only then can the chain be upgraded from a "trust machine" to an important "engine" leading the industry wave.

Decentralization. Prevent cheating. It used to be that one person kept accounts and could make changes. Now there are 50 people. Each person records an entry and everyone has a record in the account book. Can you make changes to all 50? All 50 ledgers are valid unless they are all changed. So it's very useful.

I saw many people answering that ordinary people cannot understand intuitively. Let me explain simply and clearly, blockchain is decentralized. When something happens, everyone writes it down and has their own password, which cannot be tampered with.

Even if a hacker wants to change it, he has to do it one by one, which will tire him out. In fact, it is impossible, at least for now.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms.

Blockchain originated from Bitcoin and is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of cryptographic methods. The associated data blocks are generated. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information and generate the next block.

Blockchain has potentially huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.

After reading so many expert advices, I am still confused. I only remember that someone used this so-called "blockchain" to do pyramid schemes...

2. What exactly is blockchain

What exactly is blockchain? In essence, blockchain is a distributed, decentralized network database system that will make the storage, update, maintenance, and operation of data different. Blockchain has four indispensable core technologies, namely: distributed storage, consensus mechanism, cryptography principles, and smart contracts.

Then let’s talk about how blockchain is different from traditional data processing to help everyone understand what blockchain is and give everyone a general understanding of blockchain. cognition.

1. Data storage in blockchain: block chain data structure

In terms of data storage, blockchain technology utilizes "block chain data structure" To verify and store data.

What does the blockchain structure mean? Everyone has seen an iron chain, with one link within another. In fact, each link can be regarded as a block, and many links are linked together to form a blockchain.

How does this so-called "iron chain" store data? To put it simply, the difference between blockchain and ordinary stored data is that on blockchain, the data in the next block includes the data in the previous block.

Take reading as an example: when we read a book, we read page 1, then page 2, page 3...
What about in the blockchain? If each block is marked with a page number, then the content on page 2 contains the content on page 1, the content on page 3 contains the content on page 1 and page 2...Page 10 contains The content of the first 9 pages is such a chain nested layer by layer. In this way, the most original data can be traced back. This is the traceability of the blockchain.

The "blockchain data structure" of blockchain makes it traceable, which is naturally suitable for many fields, such as: food traceability, drug traceability, etc. In this way, the probability of tainted milk powder, fake vaccines, and fake and substandard food incidents will be greatly reduced, because once a problem occurs, through traceability, we can clearly know which link caused the problem, and accountability and recovery will be clearer.

2. Data update in blockchain: distributed node consensus algorithm

In terms of data update, blockchain technology uses "distributed node consensus algorithm" to generate and update data.

Every time a new block is generated (that is, when data is updated), an algorithm needs to be used to obtain the approval of more than 51% of the nodes in the entire network to form a new block. To put it bluntly, it is a vote, and it can be generated if more than half of the people agree, which makes the data on the blockchain non-tamperable.

Why do you say that? Let’s make an analogy: we compare the blockchain to a ledger, because it records data. In the traditional world, the bookkeeping power lies with the bookkeeper, and the ledger belongs to the bookkeeper alone. So in the blockchain, everyone owns this account book. If you want to update the account, you must vote. Only if more than half of the people agree can you update the account data.

In this process, we will involve several terms: distributed, node, consensus algorithm. These terms are actually very easy to understand:

Everyone Accounting (that is, everyone has a ledger, and the ledger is scattered in everyone's hands) is the so-called "distributed";

The accounting method that everyone discusses, votes for, and unanimously agrees on is The so-called "consensus algorithm";

Every person participating in accounting is a so-called "node".

3. Data maintenance in blockchain: cryptography

In the data maintenance stage, the difference of blockchain is that it uses cryptography to Ensure the security of data transmission and access.

The cryptographic principles applied in the blockchain mainly include: hash algorithm, Merkle hash tree, elliptic curve algorithm, and Base58. These principles actually ensure data security on the blockchain through a series of complex operations and conversions.

4. Data operations in the blockchain: smart contracts

A smart contract is a commitment agreement defined and automatically executed by a computer program. To put it bluntly, it is executed with code A set of transaction rules, similar to the current automatic repayment function of credit cards. If you turn this function on, you don't have to worry about anything. The bank will automatically deduct the money you owe when it expires.

The outstanding advantage of smart contracts is that they largely avoid a series of problems caused by trust.
Many of us have encountered the situation of being borrowed money: a friend who is short of money borrows 2,000 yuan from you and promises to pay back the money after the salary is paid next month, but next month he finds other excuses. Also, dragging this matter around would be pointless. We didn't have much money, but we were still friends. Even though you were depressed, let it go.

Then, with the smart contract, he can no longer default on the debt, because in the smart contractOnce the terms in the contract are triggered, the code will be automatically executed. Regardless of whether he wants it or not, as long as he has paid his salary and has money in his account, he has to pay you back.

To summarize the contents of this section, there are four indispensable core technologies in the blockchain, namely: distributed storage, consensus mechanism, cryptography principles, and smart contracts.

We can understand it this way: distributed storage corresponds to the data storage stage, the consensus mechanism corresponds to the data processing and update stage, cryptography corresponds to data security, and smart contracts correspond to data operational issues.

3. Please briefly talk about blockchain! Thank you

The simplest explanation of blockchain The most understandable meaning of blockchain
Blockchain is being used more and more widely and will play a major role. Blockchain is It has become the forefront of global technology development, and together with artificial intelligence, quantum information, mobile communications, and the Internet of Things, it is listed as a representative of the new generation of information technology.
Blockchain is a database shared across computer networks. Once a record is added to the data chain, it is difficult to change. To ensure that all copies of the database are identical, the network is constantly checking.
Blockchain Database
As we all know, data can be any information, such as transaction information. This data information can be bundled together into an interoperable data block. These data blocks can be composed one after another to form an interoperable data link. The basic part of the blockchain database is shown in the figure below:
How the blockchain operates
We take an online transaction as an example to explain the operation and steps of incorporating this transaction into the blockchain:
First Step: Record the transaction. Suppose Zhang San sells an item to Li Si online and completes an online transaction. This record data lists detailed transaction information, including digital signatures from all parties.
Step 2: The transaction record is checked through the network. Computers called "nodes" in the network check the details of the transaction to ensure it is correct and valid.
Step 3: Records accepted by the network check are added to the data block. Each data block contains a unique code. It also contains the unique code of the previous data block in the data chain.
Step 4: The data block is added to the data blockchain. Unique codes connect blocks of data together in a specific order.

4. Which one is better, blockchain or database?

Blockchain is a distributed data storage, point-to-point transmission, consensus mechanism, and modular encryption algorithm. and other new application models of computer technology. Blockchain is an important concept of Bitcoin.

It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of cryptographic methods. Data blocks generated by Tangerine correlation. Each data block contains information about a batch of Bitcoin network transactions, which is used to verify the validity of the information (anti-counterfeiting).) and generate the next block.

(4) Blockchain database ppt extended reading

Most public blockchain chains are limited by scalability. The biggest feature of blockchain technology is decentralization, which requires all ledgers in the network to handle the accounting process. Distributed accounting has high security, low misoperation rate, and is also politically neutral and correct.

However, while blockchain technology embraces these characteristics, it sacrifices scalability, cannot meet personalized supervision, and is slightly insufficient in protecting data privacy. Moreover, as the number of ledgers increases, the interaction delay will increase exponentially, which means that the more ledgers in the blockchain network, the higher the latency will be.

5. What kind of database is blockchain technology?

Blockchain is a shared distributed database technology. Although the one-sentence introduction to blockchain is worded differently in different reports, the following four technical features are consistent.

1. Decentralization (): The left side of Figure 1 describes the centralized characteristics of today’s financial system, and the right side describes the emerging decentralized financial system, which has no intermediaries and all The rights and obligations of nodes are equal. If any node stops working, it will not affect the overall operation of the system;

2. Trustless: All nodes in the system can be rented and bumped without trust. Transaction, because the operation of the database and the entire system is open and transparent, and within the rules and time range of the system, nodes cannot deceive each other;

3. Collective maintenance (Maintain): The system is It is jointly maintained by all nodes with maintenance functions, and everyone in the system participates in the maintenance work;

4. Reliable Database (ReliableDatabase): Every node in the system has the latest complete database Copying or modifying the database of a single node is invalid because the system will automatically compare and consider the same data record that appears the most times to be true.

The blockchains of projects such as Bitcoin, Ethereum, and DECENT all have these characteristics.

6. What is blockchain ppt

From an academic perspective, blockchain is a new type of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Application mode. Blockchain is essentially a decentralized database.
For example, if you are a woman, every time your boyfriend says something disgusting to you or promises to buy you something, you immediately record it and send it to all your best friends, classmates, Colleagues, as well as various groups and circles of friends, make it impossible for him to deny it anymore. This is called blockchain.
The core advantage of blockchain technology is decentralization. It can realize decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. peer-to-peer transactions, coordination and collaboration, thereby solvingIt provides solutions to the common problems of high cost, low efficiency and insecure data storage in centralized institutions.
The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. , which has had a relatively large impact on the domain name industry.

7. What exactly is blockchain, and what is its connection with Bitcoin?

The Laikelib blockchain underlying architecture operation team believes that: Blockchain technology, It can be understood as a public accounting mechanism. It is more of a technical solution than a specific product. The basic idea is to establish a set of public ledgers on the Internet, and all users in the network will jointly record and verify accounts on the ledgers to ensure the authenticity and non-tamperability of information. The reason why it is called "block" chain is because the structure of blockchain storage data is composed of "storage blocks" on the network to form a chain. Each block contains all the information in the network within a certain period of time. Exchange data and the chain grows over time.
The relationship between blockchain and Bitcoin: Bitcoin was once one of the most successful applications of blockchain technology. Specifically, the blockchain is a series of data blocks generated using cryptography. Each data block contains information that is effectively confirmed for multiple Bitcoin network transactions. It can be said that Bitcoin is a "killer application" of blockchain thinking. Blockchain is the underlying technology of Bitcoin, but its role is by no means limited to Bitcoin.

8. What is blockchain and how to make money with blockchain

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" and created a reliable "cooperation" mechanism, which has broad application prospects.
The ways to make money in the blockchain are as follows:
1. Coin speculation. Coin speculation is like stock speculation. Coin speculation is the lowest threshold for making money in the blockchain;
2. Vendors, district Blockchain is a global market. Like small traders, you can move from a low-price platform to a high-price platform to sell and earn the difference;
3. Earn commissions for promotion. The blockchain method is to register first Exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you can get a commission;
4. Mining, "mining" in Bitcoin is The accounting process;
5. Technical support, providing blockchain technical support to some teams and enterprises;
6. Opening a trading website and charging handling fees;
7. Developing wallets and wallets It is the infrastructure of the blockchain, just like the “Alipay” or “WeChat Pay” of the blockchain;
8. DoBlockchain projects or infrastructure equipment suppliers.

Warm reminder: The above explanation is for reference only and does not make any suggestions. There are risks in entering the market, so investment needs to be cautious. Before making any investment, you should ensure that you fully understand the investment nature of the product and the risks involved. After understanding and carefully evaluating the product, you can make your own judgment on whether to participate in the transaction.

9. "Hot Spot Observation" is based on blocks Chain as the core technology moves towards web3.0

Recently, according to foreign media reports, Meta Platforms will provide deep compatibility with blockchain technology, integrating social systems with blockchain, cryptocurrency and other Web3.0 technologies combine. In the next decade, blockchain technology may have a profound impact on the industry. Web3.0, the future Internet, will also be a brand new business model, and it has become a new trend.


What is the difference between Web3.0 and Web2.0?




The profit model is different: Web2.0 whether online Advertising business, SP value-added business or other charging models all require the detonation of user information on this platform; Web3.0 has a clearer and feasible profit model, and has certain fair incentives for the development team. Through Token and certain communication The license is reserved to motivate the development team, so that the development of the protocol can truly generate value and generate more practical scenarios. As the value of the token increases, corresponding returns can be obtained.


With every change, the respective positioning and relationship between users and the network are changing: users have gone from being passive recipients of content to becoming the main creators of content. and viewers, while the network has evolved from a single content-carrying platform to a service provider that can intelligently provide users with more customized help.


Web3.0 has the following characteristics: Information sources are individualized, and the sources of information gradually return to individuals instead of some authoritative institutions; communication channels are diversified, and information The dissemination of information is no longer limited to a single media and platform; customized information has become mainstream. Under the first two characteristics, information is bound to grow explosively, so how to provide customized information for users within a limited time is inevitable.


The role of blockchain in Web3.0


A network composed of many independent nodes, even if One or two nodes are compromised by hackers, and there are thousands of nodes that store safe and effective data. Even if a node is paralyzed, it can still operate normally. A decentralized network that completely removes the middleman, does not need to trust any company, does not need to trust any third party, the code is the law, just trust the mathematical and computational principles on which the blockchain is built.


The consensus mechanism of the blockchain does not require a centralized authority to make decisions. All nodes in the network that save data are driven by incentives and pooled Decisions are made together: what state the database should be in, which transactions should be accepted, and which transactions should be rejected, which determines the authenticity of the blockchain database. Blockchain has brought a new economic model to Web3.0. It is no longer the company with a centralized server that has huge wealth. Blockchain gives value to the network itself and the community members connected to the network through tokens.


The intervention of blockchain, because of its decentralization and non-tamperable data characteristics, has accelerated the arrival of the Web3.0 era and further improved it. The Web3.0 era is an all-round expansion from the Internet to life.
