『一』Why can the digital currency generated by blockchain have economic value

Blockchain is a new route that ordinary people cannot understand, and it has great significance for discussion. Cryptocurrency has been recognized by some countries for a long time, so it has generated value. In fact, it has existed and been traded for a long time. There are many people who accept the value, so people who don’t understand can stay away. If you don’t understand and object, you can only More worries.

The value lies in the fact that the United States has Bitcoin. If we don't issue a similar coin, we'll be cut off forever. It is also the only way to reduce the outflow of RMB.

Blockchain is a deeper science and technology in the era of Internet big data. It represents the top technical achievements of artificial intelligence and has a wide range of applications. It empowers and superimposes to create more widespread socio-economic value. .

The application of blockchain in payment scenarios is fast and simple, and its calculations in data science are precise and fast. Big data storage and retrieval application scenarios cover all aspects of society, politics, economy, culture, military, science and technology, etc. Manufacturing, including agriculture, has more practical and empowering prospects that can be converted into productivity and improve production efficiency. It is the forefront of digital economics in the era of big data.

The digital currency generated by the blockchain represents the generation process of the blockchain and is the representative of the blockchain. Different algorithms have different names and types of so-called digital currencies, such as parachains and tree-structured chains. It is now a time when all heroes are rising and falling, and there is a mixture of good and bad, and it is also a time when leadership, management and control, talent, and empowerment are moving in depth. stage of development.

The reason why the digital currency generated by the blockchain is valuable is the broader application scenarios of the blockchain. Digital currency is not a currency in nature. It does not have the basic functions of currency stability, payment, storage, and trade settlement. It does not have a sovereign country to prepare a document, and it has great risks and opportunities.

For the digital currency represented by the blockchain, decentralization has extremely positive meaning from a conceptual perspective. The desire for consensus, co-creation, co-construction, and sharing of communism is understandable. Let us try to see how far it can go. Wait!

If you would like to communicate, thank you!

『二』What effect does blockchain have on real life

Blockchain is essentially a disintermediated database, which uses a blockchain-style data structure to verify A new distributed method that stores data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses smart contracts composed of automated script codes to program and operate data. Infrastructure and computing methods. In layman's terms, blockchain is a distributed accounting technology, which has the characteristics of decentralization, non-tampering, and node consensus mechanism. Although it sounds a bit obscure, it can actually bring tangible benefits to our daily lives:
First, blockchain technology can be usedTechnology can be used to establish a food and vegetable traceability mechanism to fundamentally eliminate source pollution of food and vegetables, and provide the people with safe and hygienic green food and vegetables, so that everyone can buy and eat with confidence;
Second, blockchain technology can be used to store various ownership certificates and notes and transcripts, to completely prevent the occurrence of fraud such as fake certificates, fake files, fake academic records, fake medical records, fake transcripts;
Third, blockchain technology can be used to vote in community elections, to completely eliminate fake votes, and truly achieve openness, fairness and impartiality . Build a democratic community and achieve democratic governance.
In addition, blockchain technology can also be used in many aspects of daily life such as charity fundraising and commodity anti-counterfeiting.

『三』The importance of blockchain wallet

Now more and more people are beginning to participate in blockchain projects, and those who understand and participate in it believe that they will use it. Blockchain wallet, the "wallet" here refers to a virtual tool used to store and use virtual currency.

Wallets are mainly divided into cold wallets and hot wallets, which include private keys, public keys and auxiliary words. Next, I will explain their differences and functions in detail.

Cold wallet: A cold wallet refers to a wallet that is not connected to the Internet and stores digital currency offline. Users generate digital currency addresses and private keys on an offline wallet and then save them. The cold wallet integrates functions such as digital currency storage, multiple transaction password settings, publishing the latest market conditions and information, and providing hard fork solutions, which can effectively prevent hackers from stealing.

Hot wallet: Hot wallet refers to a wallet that needs to be connected to the Internet. It is more convenient to use, but now the network is more complex, there are many phishing websites, and there are risks, so it is difficult to use a wallet or exchange. It is best to set different passwords and enable secondary authentication to ensure the security of your assets.

In summary, cold wallets are more secure than hot wallets.

Private key: The private key is a string of data generated by a random algorithm. It can calculate the public key through an asymmetric encryption algorithm, and the public key can then calculate the currency address. The private key is very important, as the password is hidden from all but the owner of the address. Blockchain assets are actually on the blockchain. The owner actually only owns the private key, and has absolute control over the blockchain assets through the private key. Therefore, the core issue of blockchain asset security lies in the storage of the private key. The owner must keep it safe. Compared with the traditional form of username and password, the biggest advantage of using public key and private key transactions is to improve the security and integrity of data transmission. Because of the corresponding relationship between the two, users basically do not have to worry about the data transmission process. The possibility of being intercepted or modified by hackers. At the same time, because the private key encryption must be decrypted by the public key it generates, the sender does not have to worry about the data being forged by others.

Public key: publicThe key appears in pairs with the private key, and together with the private key form a key pair, which is stored in the wallet. The public key is generated from the private key, but the private key cannot be derived from the public key. The public key can obtain the wallet address through a series of algorithm operations, so it can be used as a certificate of ownership of this wallet address.

Mnemonic phrase: The mnemonic phrase uses a fixed algorithm to convert the private key into more than ten common English words. The mnemonic phrase and the private key are interoperable and can be converted into each other. It is just a friendly format for the private key of the blockchain digital wallet.

Keystore: Mainly common in the Ethereum wallet App (Bitcoin is similar to the Ethereum Keystore mechanism: BIP38). It is obtained by re-encrypting the private key through the wallet password, and the mnemonic phrase Different, generally it can be saved as text or JSON format. In other words, Keystore needs to be decrypted with the wallet password before it is equivalent to the private key. Therefore, Keystore needs to be used with the wallet password to import the wallet. When a hacker steals the Keystore, without a password, it is possible to unlock the Keystore by brute force cracking the Keystore password. Therefore, it is recommended that users set a slightly more complicated password, such as adding special characters, at least 8 characters, and make it safe. storage.

In summary: The function of the wallet is to protect our private key. The private key is the full authority to control the assets. Only those who have the private key can use the virtual currency in this account. When using the wallet, remember not to disclose your wallet's private key, mnemonic phrase, Keystore and other information to others. This information is important information that can directly steal your digital assets.

Things to note when using the wallet:

1. Make a backup copy of the private key and mnemonic phrase. It is best to write a handwritten copy on your mobile phone and save it.

2. Do not click on unknown websites easily.

3. Do not take screenshots or take photos to save.

In short, the most important thing is to keep your private key.

『四』 A brief discussion on the relationship, role and prospects of blockchain and payment

A way that can solve many procedural problems, blockchain is a decentralized model, and It is transparent and open. Now many payment channels are studying blockchain technology, maiteng

『五』What is blockchain and what is the role of blockchain

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

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

Blockchain (Blockchain) is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains Collects a batch of Bitcoin network transaction information 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 non-tamperable. 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. Here are some common ones: bitcoin, litecoin, dogecoin, OKcoinetc. In addition to currency applications, there are also various derivative applications, such as NXT, SIA, and BitShares. , MaidSafe, Ripple, Ethereum and many more.

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 that digital currencies are reducing the issuance of traditional currencies.value in other aspects, 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 the 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 be carried out with blockchain as the underlying logic, and many things will be within our reach. , coupled with the integration of artificial intelligence and big data, we can easily handle things that may seem cumbersome now, such as some securities market transactions and intelligent matching of financial management activities.

In layman’s terms, blockchain is the integration of people, money and goods, people, machines and goods, people, places and goods, and packages them into a whole; putting it on a foundationfacilities 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 + payment

8. Blockchain + invoice {already enabled in Shenzhen}

Blockchain traceability and The combination of non-tamperability and the inherent nature and needs of the financial industry 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?

In summary, the blockchain is to hide privacy in a decentralized manner, record any actions that reproduce this privacy, and make it public. 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 depend on the rightPower is destined to become another beautifully packaged lie, a cover for deception. In this sense, the government must also specify a framework for the development of the blockchain, reconstruct the value of the blockchain, and drive out 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 and fix them, using computer and Internet encryption technology to prevent secrets from being leaked to the outside. This technology cannot be explained to non-professionals through professional terms Normally people can’t understand it. I can only explain it with an analogy. Let me give you two examples:

1. Four people, A, B, C and D, play mahjong in a mahjong parlor to gamble, using chips for each round. When the gang breaks upIn one settlement, A lost 1,500 yuan, B lost 300 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 a 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 present, no one else knows about this. If A wants to default on the debt and says that he does not owe money at all, only three people, B, B, D and D, know that A is defaulting on the debt. It is difficult for others to judge whether A owes money and refuses 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 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 this group knows, 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 characteristics of the blockchain:

- "1" summarizes the blockchain: a trusted distributed database;

- "2" core properties: distributed, non-tamperable;

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

The "distributed" and "non-tamperable" nature ensures 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 it 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 just remember that someone used this so-called "blockchain" to do pyramid schemes in the past...
