『一』What are the benefits of nationwide distributed accounting of blockchain technology?

As for the benefits, Jin Wowo feels that the biggest benefit is the great security. . First of all, there is a central ledger, so it cannot be destroyed. Each node is just a part of the system. Each node has equal rights and has exactly the same ledger. Destroying some nodes has no impact on the system at all. Secondly, you cannot cheat, because unless you can control the computers of most people in the system to make modifications, the system will refer to the opinions of the majority of people to determine what the real results are. As a result, you will find that modifying your own ledger is completely meaningless (because other people deny). Secondly, since there is no centralized intermediary agency, letting everything run automatically through preset programs can not only greatly reduce costs, but also improve efficiency. And since everyone has the same ledger, it can ensure that the ledger recording process is open and transparent.

『二』What is blockchain and how to make money with blockchain

What is blockchain

With the popularity of blockchain, domestic Some companies have also begun to claim to have developed products with blockchain technology under the banner of blockchain. For most people, although they hear a lot about blockchain, few people really understand it. Blockchain, so what is the arrival of blockchain?

Simply put, we can understand the blockchain as a public ledger. I believe everyone is familiar with the account book mentioned. Whether it is a company or an individual, it will keep accounts. In the traditional accounting method, there will be a person who specializes in accounting, and there will be a unified account book. The account book will be kept by the account keeper. Blockchain technology is a kind of "decentralized" and "trustless" distributed accounting, that is, there is no central ledger and no unique accountant. All people can participate in accounting. Once the accounting is successful, everyone can participate in accounting. Everyone who makes an account has an account book, which can prevent the account book from being modified or the accounting data being lost.

Let’s take an example: When people usually shop on Taobao, because they don’t know much about Taobao merchants, we need to use a third-party platform, Alipay, to build trust between buyers and sellers. , and blockchain technology means that we no longer need a center like Alipay to build trust between buyers and sellers. After the transaction, both parties will notify someone to help record the transaction. Everyone has recorded the transaction, and everyone has Have a ledger. This is the decentralized and trustless accounting method of blockchain technology.

How to make money in blockchain

1. Coin speculation. BitBit, which has been very popular in recent years, is the earliest project to apply blockchain technology. The lowest threshold way to make money in blockchain is to speculate on coins. Investors can make reasonable use of time and other factors to buy and sell digital currencies. Earn the difference. Although this method is used by many people, I would like to remind everyone here that there are risks in speculating in coins.Risks, everyone needs to invest cautiously.

2. Mining. Obtain digital currency through mining. For example, in Bitcoin mining, miners need professional mining machines. The process of "mining" is actually accounting. When the accounting is successful, the miner will receive Bitcoin as a reward.

Although blockchain projects are very popular in the market, there are also many scams using blockchain to defraud people. At present, blockchain is still in its infancy, and blockchain technology is still in its infancy. If it is not perfect enough, blockchain investment is also risky, so everyone needs to be cautious when investing.

『三』What does distributed accounting of blockchain mean?

This is a good question. Let me give you an example. For example, I deposited 100 yuan in the bank. This The deposit data is only recorded in the bank's database and cannot be obtained by others, which is "centralized accounting". The blockchain is a distributed accounting, a new information recording technology, and it is "encrypted" and "distributed". The data no longer exists in a center, but is stored once on all computers in the network. . For example, if I transfer 100 yuan to you, I will shout to all the computers in the entire network, and everyone will keep an account together, which is "distributed accounting".

『四』What is the essence of blockchain

Blockchain is essentially a decentralized distributed database, a distributed data storage, multi-center point-to-point Innovative application models of various technologies such as transmission, consensus mechanism and encryption algorithm in the Internet era.
In layman’s terms, the blockchain can be compared to a “ledger”. The traditional ledger is "centralized accounting" by one party. This new "accounting book" can be participated and shared by multiple parties on the Internet. Each participant can "accounting" and back up, and each backup is a "block". Each "block" is linearly connected to the next "block" in chronological order, and its structural characteristics make the record impossible to be tampered with and forged.
For example, if you are the one doing the accounting at home, and your parents give you a salary and let you record it in the account book, then because you are the only one keeping the accounting, you secretly spend more than ten yuan, Maybe they won't know, but now it's your parents who keep the accounts with you, so whether it's your father who wants to buy cigarettes secretly or you who want pocket money, every move will be clearly recorded in the account book.

『五』What is blockchain? A popular explanation of a new accounting method (you will understand after reading it carefully)

In the past two years, there has been a The new financial model is "blockchain". I think many people still don't understand the meaning of this. After all, "blockchain" is still "advanced" to ordinary people, so blockchain What is the popular explanation? In fact, it is not as complicated as we imagined, so let me tell you what "blockchain" is and see what characteristics this model has.Something else!

The most popular explanation of blockchain:

What exactly is the "blockchain" that people often talk about? I believe that many people don’t know much about it, and most of the information they view on the Internet is “unclear”. In fact, it is easy to understand. So what is the popular explanation of blockchain? Fundamentally speaking, this model is a "decentralized" accounting method. So what is "decentralization"? All our current exchanges and communications on the Internet will actually be stored in a "centralized" server on a browser or APP. The other party can check our browsing information at will, and "decentralization" is convenient. This can be completely avoided.

Once the information is written into the "blockchain", it cannot be tampered with, ensuring its authenticity and confidentiality. It can also avoid third-party platforms in transactions on the virtual market. Intervention, the transaction is directly completed by both parties, which saves a lot of procedures and time, and also ensures that information is not leaked, transparent and other security issues, and there is no possibility of data loss!

After reading the above introduction, do you have a new understanding of the "blockchain" model? can't read? Let’s take a look at it through a comic below!

Fields of application of blockchain

The "blockchain" model can be applied in many fields, the first of which must be finance. The earliest blockchain is from Born in Bitcoin. This new technology can also be used in education, e-commerce, film and television, etc. Now all walks of life are exploring this new field, hoping to have a foothold in the development of the future era!

『Lu』 Introduction to Blockchain (1) - Let’s keep accounts together

When I was a child, I was very curious about many novel things and full of desire to understand and learn. At that time, countless exclamation marks often appeared in my brain. As I grow older and gain more experience, this kind of experience becomes less and less common, and I am not surprised by the new things that many people follow. When "blockchain" first appeared, I was completely attracted. After that, just like when I was a child, I was instinctively driven to learn and understand deeply, and found that "blockchain" is a new world that is about to come. s future.

The first time I heard the word "Blockchain" was in teacher Li Xiaolai's column "The Road to Freedom of Wealth", and I read it many times in the column after that. to the emergence of this term. Out of curiosity, I followed and read the articles on Lao Mao's public account "Cat Talk", and gradually learned about the blockchain from 0 to 1.understanding. block-block, chain-chain, blockchain-connect the blocks one by one into a chain, imagine the DNA extending infinitely in front of you...

This paragraph is about blocks on the network An explanation of the chain, to put it in simpler terms, the blockchain is an open, decentralized, trustless, and jointly maintained accounting system.

Let’s first look at the traditional centralized banking business model. When we do transactions, why do we need third-party centralized companies such as banks, Alibaba, and Tencent? Because there is no trust between people. A lends B 100 yuan today. If B does not recognize the loan tomorrow, what will A do? The bank helps solve this problem. Everyone creates a real-name certified account in the bank. With the help of this centralized company, A lends 100 yuan to the bank (deposit), and B takes out 100 yuan from the bank (withdraw/borrow). Then the bank Responsible for recording this transaction, A's account will be 100 yuan more, while B's account will be 100 yuan less. This method of relying on third-party centralized companies for accounting can be seen everywhere in our lives: for online shopping, we need Alibaba's Taobao City and JD.com; for loans, we need to find reliable small loan companies; for new books, we need to go through a certain publishing house... …In the final analysis, it’s because people don’t trust each other, or the risks and costs of maintaining trust are too high, so we need such centralized and powerful third-party companies to endorse transactions and let them Taking these risks, of course, they also make us money. However, relying on third-party centralized business models has brought us inefficient services, cumbersome procedures and diversion of value, such as banks queuing up to handle business, the lending process of small loan companies, and Taobao and JD.com’s rent collection from merchants. , the publisher’s share of the author’s manuscript fee, etc. This is the centralized, third-party trust-based world we currently live in.

The blockchain world is a new world where no third party is needed, all transaction information is public, and everyone participates in bookkeeping! As the world's first proven and feasible blockchain application, Bitcoin subverts the traditional financial model by using automatic accounting and open accounting, information cannot be tampered with, and can be queried at any time, bypassing third-party centralization. Buyers and sellers conduct transactions directly. Such a transaction model must be efficient, low-cost, and open. Just imagine if blockchain technology becomes popular in the future, when you want to transfer a large amount of money to a friend abroad, you can skip the lengthy steps and get it instantly; if you write a book and publish it, you don’t have to worry about being pirated. There is no need for the publisher to earn your royalties; a peer-to-peer mutual insurance platform will be built directly between people, and the insurance company will become a consulting company, etc. (In fact, Bitcoin and Press.one are realizing such a subversion)

The Internet is currently booming. We have Didi taxis or shared bicycles for outside work. When ordering food, we choose Ele.me and restaurants.There are Dianping reviews for dining, and convenient payments via WeChat and Alipay are everywhere. When we pay on the Internet, we need to rely on a third-party platform company trusted by both buyers and sellers to complete the transaction for us. These third-party companies have a large amount of transaction data and information on both parties to the transaction. If a hacker intrusion occurs and information is lost, we will bear the consequences for our "trust risk"; not to mention the delays caused by reviewing and clearing transaction data. The inconvenience, and the huge cost of managing such a huge amount of data.

So how is blockchain technology implemented? For example, if there is an army that wants to seize an enemy fortress, and each soldier wears a special helmet with a red button, each time a fortress is captured, the army headquarters will award a medal. First, a soldier A took the lead in occupying the first fort 1. He announced to other comrades through his helmet that he had occupied fort 1. At this time, the helmet would record the coordinate information of fort 1 and pass it to other soldiers along with A's shouting. All soldiers and others heard A's shouting through the helmet and pressed the red button to indicate that the message had been recorded simultaneously. Then everyone knows that fortress 1 has been occupied by A, and A is rewarded with a medal. Then others will immediately capture other fortresses and broadcast their achievements in the same way. In this way, the information that different fortresses were captured by different soldiers in this battle is all stored in everyone's helmet. Here, the helmet is the public ledger (strictly speaking, the helmet's program), and everyone participates in accounting; each captured information constitutes a block, and all information arranged in a certain order forms a blockchain; In addition to keeping accounts (pressing the red button), participants also scramble to grab the right to package new data (capture the fortress).

So let’s take a look at the advantages of this joint accounting method. 1. Decentralization. The ledger is jointly recorded and maintained by everyone. It doesn’t matter who records it first, because if there is an incentive (medal), someone will do it, and there is no need for a third party to intervene (no need for the command of a general or combat department, which reduces military expenses and commanders) risk of sacrifice). 2. Data cannot be tampered with. If you want to modify the accounted data, you must modify more than 51% of the node information to succeed. Just imagine, if this army has one million people (actually the number of blockchain nodes is much larger than this number), it would be an almost impossible task to modify the helmets of more than half of the army. 3. Information is open and transparent. Everyone can check this transaction information in their own ledger (all fortress capture information has been recorded in everyone's helmet).

This is the first article I started writing. The last time I wrote so many words was probably in the college entrance examination. The first article was about a new field that I had never touched before. The text was a bit confusing and mediocre, and I didn’t know whether the analogy I made was correct or not, but I finally started to do it. Writing is indeed a skill that everyone should have, and it can beSkills that have been improved through deliberate practice, and urge yourself to maintain them.

『撒』 This is what transactions on the blockchain are like

Transactions on the blockchain are actually very simple and not mysterious. To understand transactions on the blockchain, let me first look at a transaction in daily life.

What would happen if the payment method of this transaction was moved to the blockchain? Before talking about blockchain transactions, let’s briefly talk about blockchain transaction accounting.

1. What is blockchain

Blockchain is simply B’s ledger. A block is a page in this ledger, used to record transaction information. For example: On December 14, 2017, a computer was sold and a profit of 5,000 yuan was made. All blocks are strung together in order to form a blockchain, that is, a ledger.

2. Characteristics of blockchain

Blockchain is a distributed accounting network. If it is difficult to understand, you can compare it with the centralized accounting network of Alipay, as shown below: < /p>

The central approach is like having only one accountant. Only this accountant knows how the transaction is going. Distribution is like a bunch of people keeping the same account and making a transaction, everyone knows about it. A relatively small group with only one person knowing the information. An information disclosure and transparency.

3. Blockchain transaction accounting

In Alipay’s centralized accounting network, transfers only require Alipay to confirm and record the transfer behavior, and then the transfer can be completed and recorded. .

In the blockchain of the distributed accounting network, each transfer transaction will be sent to each node and confirmed by them before the transfer can be completed and recorded.

To put it simply, one person has the final say in a centralized accounting network, while everyone has the final say in a distributed accounting network. If anyone lies or commits fraud, they will be able to spot it quickly because everyone has a copy in their hands. Exactly the same ledger.

If A chooses Alipay to transfer payment to B, the operation process is as follows: open Alipay -> click on transfer -> enter the other party's Alipay account -> enter the transfer amount -> click to confirm the transfer -> enter the password. Whoosh, the money was in account B.

If A chooses to pay B with BTC, if the current 1 BTC = 100,000 yuan, then A needs to pay 0.05+0.001 = 0.051 BTC to B, of which 0.001 BTC is the mining fee.

The operation process is as follows:

In terms of operation, the transfer process is similar. Maybe you don’t understand what an address is? What the hell is the mining fee? What are those 6 confirmation numbers? No rush, come one by one.

1. Blockchain address

The address can be understood as B’s Alipay account.When A transfers money to B, he naturally needs to know the other party's "account number" so that he can transfer money there. The following is a BTC address:

It is a string composed of numbers and letters.

How is this address generated? It is generated by the public key through a one-way hash function. You can leave it alone and it is automatically generated. Unlike Alipay, you can choose the Alipay account name according to your personal preferences when applying for an account.

What else can the address be used for? To check the "account" balance and transfer transactions, you can check the balance and transfer records under any valid BTC address on the btc.com website, as shown in the following figure:

2. Transaction confirmation number

In the blockchain distributed accounting network, every transfer transaction is confirmed by a node in the network, and one transaction confirmation number is recorded. However, it will take a long time for the transfer to take effect only after confirmation from all nodes in the network. Therefore, in the BTC network, based on design calculations, when 6 transaction confirmations are obtained, the transaction can be considered very safe, the transaction takes effect, and the transferred BTC can be received.

3. Mining fees

Mining fees are the "tips" paid by A to the BTC network provider when A transfers money to B to encourage them to provide services for the BTC network. The "tip" can be adjusted. The more "tip" you give, the faster the transfer speed will be.

4. Transaction progress query

BTC transfer generally takes 0.5~1h. Faced with such a long time transfer, it is inevitable to want to check the transfer progress to comfort the anxious mood. How to check it? ?

You can query by address, as above. It can also be queried by TxID.

What is TxID? TxID is the abbreviation of transaction ID, which translates to: transaction ID.

When the transaction information is packaged and sent to the network, a TxID will be generated, but it is used to view transaction-related information, somewhat similar to a receipt. The status of any transaction ID can be queried through the btc.com website, as shown in the query result below:

At this point, you can easily transfer transactions on the blockchain, check account status and transfer progress.

『八』Blockchain principle

Blockchain is a technology, but It is not a single technology, but the result of the integration of multiple technologies, including cryptography, mathematics, economics, network science, etc. You can think of it as a distributed shared accounting technology, or as aA database, but this database is jointly maintained by all nodes in the chain. Each node has a ledger. Because the ledgers of all nodes are consistent, different nodes can trust each other and have no doubts about the data, so everyone It is said that blockchain technically achieves trust. For detailed professional technology, you can consult some professional technology companies. For example: Jinbo Technology, which focuses on developing blockchain-related products, has a professional R&D team and complete after-sales service. You can call for consultation.

『九』 What is blockchain

The poster must first understand 2 logics.

One is blockchain technology and the other is blockchain investment (a mixture of good and bad, need to be distinguished).

Blockchain is essentially a decentralized distributed ledger database. P is a big deal, every node on the chain will be replicated and accounted for synchronously, and the information will be transparent and difficult to tamper with. For example, if you say you want to buy a bag for your girlfriend, and she posts it to Moments, everyone knows about it and writes it down in her notebook. You can't deny it, so you have to pay for it. However, having a partner is the first step!

There are three core values ​​of blockchain technology

1. Decentralization

2. Traceability

3. Untamperable

Because of its values, it can solve many trust problems in our daily life, such as food safety, evidence preservation, etc.

It can be said that the application of blockchain in today's society is becoming more and more widespread, but there are also people who don't know much about blockchain. So what exactly is blockchain? Let me talk about my own experience!

In terms of the decentralized storage of the blockchain, the blockchain can be said to be equivalent to a distributed ledger. The memory of each block is arranged in series using the order of time to form an extensive chain. And this combined chain cannot be tampered with or forged by a third party at will, which effectively guarantees the security of the chain formed by data combination!

Moreover, the characteristics of blockchain are fully in line with the business needs of modern enterprises. Blockchains that are sufficiently decentralized and trustless will be accepted by more people over time. , I believe that blockchain will also be immeasurable in its future development.

So, where exactly can blockchain be used? I believe this is also an issue that many people are concerned about. Just like the Starlight Chain developed by Diandian Starlight, as the Starlight Chain has the same characteristics as the blockchain, more realistic distributed storage and cloud computing will be widely used in our daily life services and the Internet of Things!

In commercial storage, Starlight Chain will also play a vital role. For example, distributed hotels or smart life computing are inseparable from Starlight Chain's storage, computing and processing work.

It is said that Starlight Chain will be launched soon. If you want to own Starlight Chain, you must prepare in time! But there is another point. If you want to own the Starlight Chain, you have to mine or trade it. If you don’t know it, you need to understand it in advance. Only when you know yourself and your enemy can you choose something that suits you!

What is blockchain? Everyone who knows has a little understanding and their own opinions.

The official definition of blockchain is: 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. A new distributed infrastructure and computing method that ensures the security of data transmission and access and uses smart contracts composed of automated script codes to program and operate data.

What is mentioned separately in blockchain technology is "decentralization", which means that online transactions do not require intermediaries such as Alipay, and buyers and sellers directly communicate with each other, and there is no need to worry about being cheated. If you cheat, there is no need to consider the credibility of each other.

Similar to the real-life transactions in a physical store, you give him money and he gives you things. He can see the origin of your money, who has used it in the past, and who holds it, and you can see the raw materials, the place of origin, and the specific manufacturing process. Isn’t this awesome?

In the blockchain, we are all a link in the chain. We are linked back and forth, forming a chain, a loop, and a network. Everyone is a part of it, and everyone is the last source of information for others. and accept the next message.

Regardless of whether you make money or not, participating early will always give you more opportunities.

In one sentence, if Internet technology solves the communication problem, blockchain technology solves the trust problem.

The so-called blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. In layman's terms, blockchain refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. To put it more clearly, blockchain is similar to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Then who will keep this ledger becomes very important.

At present, whoever owns the system keeps the accounts. Tencent keeps the account books of WeChat, and Alibaba keeps the account books of Taobao. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are any data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write his recorded content into the ledger, and record this Within a period of time, the contents of the ledger are sent to all other people in the system for backup. In such a systemEveryone keeps a complete ledger. In this way, we call it blockchain technology.

What? I don’t know...

How to use it? The most typical one is probably the economic profit brought about by the exponential explosive growth of Bitcoin. And now every major platform has launched its own blockchain, hoping to get a piece of the pie.

Now the most popular NetEase Planet earns Force Power by signing in every day, and earning Force Power by inviting friends. The amount of Force Power directly affects the number of black diamonds you mine. Until now So far, the eldest brother who has dug the most black diamonds probably has only about seventy, and I only have about three.

The current information provided by NetEase is that the black diamond transaction will be carried out in mid-March. At that time, it should be possible to reflect whether the black diamond is valuable. And compared with other blockchain projects, NetEase Planet must have the invitation code of the inviter before you can register.

The second one is Block City, which is also a relatively popular platform. Judging from my current situation, this platform has more types of mines, not just like Black Diamond. It is a kind of thing, and in comparison, the quantity dug is really small. So far, it is calculated based on the output of a few 0.00.

The third one is this inurswallet. I don’t quite understand this one, it’s similar to the other two, but the output is relatively large

The fourth one is this online Leitz dog. This one is a little different from the others. You can get calculus points by signing in. , or you can earn micro points by inviting friends, and you can also earn micro points by buying and selling Leitz dogs. Many people feel that there is nothing interesting about raising a dog, because they don’t need to collect it all the time like other platforms, so it seems a bit boring. The current Leitz dog is only the 0th generation, and the breeding function may appear in the later period to produce the 1st generation, the 2nd generation, etc.

Blockchain is a technology that can make data on the Internet safe, reliable and non-replicable. Moreover, there is no need for an agency or organization to take care of it.

At present, blockchain technology is not yet mature, because there are indeed technical bottlenecks, resulting in unsatisfactory data processing speed in the blockchain. The reason why blockchain is so popular is inseparable from people’s enthusiastic expectations. However, blockchain is indeed a disruptive technology. I believe that one day it will break through the technical bottleneck and truly good applications will appear.

1 and N, public and private, efficient and inefficient

(1) What is the difference between new retail and blockchain?

Many people’s first impression is that there is no essential difference between the two!

Is this really the case?

Share-holding new retail, free access for the people, restricted capital, only channel, and the end point is socialismOwnership by the whole people. Blockchain, free access to capital, limited access to the people, infinite channels and platforms (N), constantly pushing up channel costs, always points to capitalist private ownership. One is 1, the other is N; one channel has decreasing costs, one channel has increasing costs; one points to socialist ownership by the whole people, and the other points to capitalist private ownership.

(2) What is the difference between new retail and traditional networks?

Many people feel that new retail will help everyone make money in the future, and will be the same as the traditional Internet in other aspects.

Is this really the case?

Consumer-led new retail has free access for consumers and producers, limited capital, and unique channels. The end point is zero marginal cost and a high degree of system security and stability. In contrast, today's traditional networks have free access to capital, and the number and cost of channels are constantly increasing. Each platform may not see the sun next year, and the platform is logically unsafe and unstable. One is 1, the other is N; one is cost-decreasing, the other is cost-increasing; one is a benefit entity, and the other is a pitfall entity; one is heading towards stability and unity, the other is heading towards division and conflict; one is pointing towards common prosperity, and the other is pointing towards polarization.

(3) What is the difference between new retail and the commercial banking system led by the Federal Reserve?

Consumers dominate new retail, with only one channel. Consumers and physical enterprises have free access. The end point is the lowest-cost channel and socialist public ownership. Commercial banks have free access to capital, and the end point is that channel costs are constantly rising, which not only squeezes physical profits, but also points to debt and economic crisis. One is 1, the other is N; one is free access for people, and the other is free access for capital; one is zeroing out channel costs, pointing to happiness, and the other is gradually increasing channel costs, and the economy is driven by investment, which ultimately triggers an irreversible environmental crisis. .

(4) Great simplicity, all methods unified

Channels do not directly create value!

The fewer channels, the higher the efficiency. New retail has free access for the people. To maintain the uniqueness is to maintain the lowest cost and to maintain the road to the future!

Looking at blockchain, traditional networks and commercial banking systems, their starting point is N. The more they struggle, the greater the damage to the entities they depend on, and the closer they are to death.

——What is socialist public ownership?

All enterprises are linked by a new retail link into a super enterprise, which only bears production and transportation costs. The wealth of society is determined by production capacity, not by capital and financial algorithms. Strong and excess production capacity determines common prosperity.

——What is capitalist private ownership?

With free access to capital, you can mess around. The number of channels and platforms continues to increase, and channel costs increase exponentially, squeezing entity profits., inhibiting physical enterprises from serving the people. Channels here include blockchain, traditional networks, commercial banking networks, etc. The essence of private ownership is to be conservative and fish in troubled waters.

What is blockchain? This word seems to have become a question that people who have done a little research on the Internet will ask in 2018.

The emergence of blockchain as a new concept word, many people cannot understand it at first. We take the Starlight Chain of Diandianxingguang, code: STA as an example.

Starlight Chain is based on blockchain and has the characteristics of blockchain such as decentralization and trustlessness. The so-called decentralization and trustlessness mean that point-to-point transmission can be carried out in the future, and Starlight Chain Chains can achieve this. The details are as follows:

Based on the decentralization, distribution, point-to-point transmission, non-tampering and other characteristics of the blockchain, the uploaded data will be stored in slices and backed up multiple times and encrypted for storage. Obtaining any one or more pieces cannot constitute complete data. When part of the stored data is lost or damaged, in order to ensure the security of the data and download it at any time, the system will automatically generate a new backup, and only the private key can be used to download, change or delete.

Blockchain is used to jointly record public data, or in a more narrow sense, for accounting.

You said that you can just use a computer to record the accounts yourself. Why do you need a blockchain to record them?

Because others don’t believe the accounts you keep. Who are you? Why do others believe what you remember?

For example, you recorded in your computer that Zhang San owes you 10,000 yuan, and Zhang San said that I also recorded in my computer that you owe me 1 million yuan. What to do?

This used to be the solution: Find a notary, and both of your accounts will be recorded with the notary. If there is a dispute, the notary's account book shall prevail. For example, this is what banks do. Both of your money is deposited with him, and there are records of transfers and borrowings.

The blockchain solves this problem: when you are keeping accounts in your own computer, Zhang San will also keep the same data in his own computer. After recording, you two will check each other and both agree. Okay, this account is officially recorded. There is no need for third parties or so-called "authoritative agencies" or "certification agencies" to participate in the process.

The way everyone keeps accounts together is also called "distributed" or "decentralized" because everyone keeps accounts, and the accuracy of the ledger is determined by a program algorithm rather than a certain an authoritative organization.

This is the blockchain. The core is finished. The blockchain is as simple as a common ledger.

What is blockchain?

First of all, let’s clarify the concept. Blockchain is a computer technology that integrates multiple disciplines. It is the same as the Internet.In this way, it is an electronic platform for processing information data.

Blockchain is not equal to digital currency. Digital currency only applies blockchain technology to increase its uniqueness and security, making it difficult to counterfeit. These digital currencies are actually strings of digital information codes.

Then answer two sub-questions:

(1) How to use blockchain technology

To figure out how to use blockchain, we must First figure out how it works and what its advantages and disadvantages are.

Simply put, on the blockchain platform, the data will be processed and packaged into a fixed size, and then encrypted to generate unique verification information, and the verification information will be used to complete the concatenation of the data. The middle information block will contain the verification information of the previous block and generate new unique information for use by subsequent blocks. Because the generated verification information is unique, changing any of its contents will produce another different verification information. Therefore, blockchain uses this to ensure data security.

On this basis, the blockchain uses distributed storage to store copies of data in the hands of everyone participating in the blockchain. Only the consistent data information is recognized. information. If there are different copies that are different from the majority, then its data is tampered with, that is, forged.

Blockchain also has other features, such as instant broadcast, status synchronization, smart contracts, automatic operation, and public sharing.

When we use blockchain technology, we must think about what actual problems this technology can solve and whether there are any other alternative solutions to these problems. If the cost of using blockchain technology is lower, then it can be adopted.

For example, if a company's financial information is saved using blockchain technology, each financial transaction will be securely encrypted and distributed to multiple computers in the company to save copies. Then these stored data are secure enough, and no one can unilaterally tamper with the accounts. If someone's copy of the account is different from other people's, then it is tampered with.

Such an application can save a lot of financial data review costs and create benefits for enterprises.

(2) When will blockchain mature?

Blockchain will mature tomorrow.

Haha, of course this is impossible. To say when the technology will mature, you need to consider where it will be used, whether it is for commercial or civilian use, or for simple data applications. To what extent do you want to use technology?

For example, when will Internet technology mature? Can you call me mature now? What are the criteria for maturity? For civilian use, Internet technology is relatively mature because it can already meet people's daily information processing needs. But for commercial use, Internet technologyThe technology is not mature enough because it still has some technical bottlenecks. This is why Alibaba produces some transaction volume data every year during the e-commerce festival. You know, in such a short period of one or two hours, hundreds of millions of information flows in. How to deal with it? Whose priority? What to do if data is interrupted? These are all questions that are emerging gradually.

Back to the blockchain, blockchain technology is still in the state of a primitive model and is still in a very preliminary stage. No one has imagined what specific changes it can ultimately bring to society. Everything is castle in the air. Even the current social foundation of blockchain is still very weak. How can we infer its maturity time on such a basis?

If I had to name a time, I would say tomorrow. Why tomorrow? Because technology is developing, tomorrow's progress will definitely be more complete than today's.

『Shi』A popular explanation of blockchain technology. The essence is a distributed ledger

What is blockchain technology? Briefly explain what blockchain is. At the beginning of 2019, a new currency began to enter the ranks of digital currencies and gradually attracted the attention of many digital currency players, that is, blockchain technology. But some people found that there is really little information about it on the Internet. This not only caused many people to wonder, what is it and why is it so mysterious? Blockchain is the earliest basic technology of Bitcoin. It is currently being studied all over the world and can be widely used in various fields such as finance.

Basic Principles Edit

The basic principles of blockchain are not difficult to understand. Basic concepts include:

Transaction: an operation that causes a change in the status of the ledger, such as adding a record;

Block: records transactions and status results that occur within a period of time, is Consensus on the current account book status;

Chain: composed of blocks concatenated in order of occurrence, it is a log record of the entire state change.

If you think of the blockchain as a state machine, each transaction is an attempt to change the state, and the blocks generated by each consensus are the participants.

Explanation Editor

Explain in layman’s terms: If we assume that the database is an account book, then reading and writing the database can be regarded as an accounting activity. The principle of blockchain technology is to find the fastest and best bookkeeper within a period of time. This person will keep the books and then send this page of information on the ledger to everyone else in the entire system. This is equivalent to making changes to all records in the database and sending them to every other node in the entire network, so blockchain technology is also called a distributed ledger.
