Ⅰ The ambition of the digital renminbi blockchain is still to decentralize the wallet to make assets safer

Recently, the digital renminbi has taken advantage of the Double 12 trend to have a "payment" "Storm", from offline merchants to online scenarios, all payment scenarios for food, clothing, housing, transportation, shopping, and entertainment are included, and high-frequency and real-time payments have verified the stability of this payment system. Of course, the connection between digital renminbi and blockchain has also attracted much attention.

Although a long time ago, Mu Changchun, director of the Central Bank’s Digital Currency Research Institute, once described that as long as you have a digital currency wallet on your mobile phone, you can pay without the need for an Internet connection. But he also said that blockchain is not yet suitable for high-concurrency scenarios such as traditional retail payments.

Although the current digital RMB does not apply blockchain technology, it cannot stop more and more people from becoming enthusiastic about its future applications in digital currencies and digital wallets.

This enthusiasm comes from the characteristics of blockchain such as "unforgeable", "leaving traces throughout the process", "traceable", "open and transparent", and "collective maintenance", and is different from digital RMB and digital wallets. Directly related is the use of decentralized wallets. Most of the current decentralized wallets are used in virtual currencies, such as the EpiK official wallet.

The value of decentralized wallets

Decentralized wallets are infrastructure in the blockchain world, and their birth can be traced back to Bitcoin. Blockchain is also known as the Internet of Value, and decentralized wallets are the key to realizing value.

In practical applications, with decentralized wallets, after users enter the asset page, they can directly view their digital assets, as well as transfer and receive payments, etc., we can easily Perform transfers, collections and inquiries.

Regarding the value of decentralized wallets, we can draw relevant conclusions by referring to Alipay and WeChat Pay, which are compared with digital renminbi.

Take Alipay as an example. It was originally just a payment application. Then with the expansion of the Internet in various areas of life, now our daily necessities, food, housing, transportation, and even some life applications can be used on the Alipay platform. For example, buying tickets, paying utility bills, shopping, etc.

If you calm down and observe the current cryptocurrency wallets, you will find that as blockchain applications continue to extend in various fields, this kind of thing will also happen in decentralized wallets.

The security of decentralized wallets

When thinking about many decentralized walletsAfter the value, the topic of security returns to the focus. After all, wallets are the storage place for important assets. How to ensure the security of decentralized wallets?

When creating a blockchain decentralized wallet, you are not actually creating an account, but just building a wallet, a tool that allows you to see your assets.

In a decentralized wallet, users hold their own private keys and mnemonic phrases and do not rely on any third-party management. Except for the user themselves, no one else or even the official will know about it. This can better protect the safety of your assets.

Taking the EpiK official wallet as an example, the platform will not save the user's private key and mnemonic phrase. If the user's private key and mnemonic phrase are lost, the wallet assets will not be recovered. Therefore, EpiK’s official announcement pointed out that as long as the user’s private key and mnemonic phrase are safe, asset security can be guaranteed.

In addition, unlike other decentralized wallets, EpiK does not allow the export of erc20 private keys. In addition to the private key, the mnemonic phrase is also critical. The mnemonic phrase is the last line of defense for asset security. , as long as the mnemonic phrase is there, you can re-import the private key if it is lost.

II Is the blockchain technology a lie? Does it have any actual connection with our lives?

How can something useful be useless

In recent years , more and more people regard blockchain technology as one of the most promising new technologies in the future. Right now, there is a lot of talk about how cryptocurrencies and blockchain will change the world economy. Although the future of cryptocurrencies is unpredictable, the unshakable status of blockchain may continue to lead the development of the industry in the future. In fact, blockchain has changed not only the world economy, but even the daily lives of ordinary people have been greatly changed by its impact. The emergence of blockchain technology itself is an innovative process. Anyone who understands blockchain technology should know that blockchain is a database that can collaborate on a large scale. It allows many different subjects to collaborate to complete a task without trusting each other. This is the essence of blockchain.

Since this year, there have been numerous cases about blockchain technology supporting the resumption of work and production of small and medium-sized enterprises.

Here we use the combination of China (Fujian) International Trade Single Window and Blockchain to illustrate

Ⅲ What are the application scenarios of blockchain

In Oracle The website lists ten industry application scenarios for blockchain

Including finance, production, education, media, entertainment, government, retail commerce, health, Healthcare, supply chain, insurance, public utilities. Yes or noIs it very noble? But what I want to say is these application scenarios. In the face of truly high-powered blockchain applications, these application scenarios can only hide in the corner and tremble.

Nowadays, the truly high-powered application scenario of blockchain is Ponzi application, commonly known as "Ponzi scheme". It is a smart contract-type Qianbao, a blockchain game with rolling deposits and withdrawals, an ICO for transaction purposes, and a global pension platform.

Ponzi scheme is one of the oldest application scenarios of our mankind. After the emergence of the Internet, Ponzi scheme has been upgraded to "Internet +", that is, "Internet + Ponzi scheme". The Internet empowers Ponzi schemes, so events like Qianbao's tens of billions occurred. Before the Internet era, there were few Ponzi schemes of this scale. Empowered by the Internet, deposits and withdrawals were made through mobile APPs, and finally rolled In a few years, it has reached a scale of tens of billions.

The Internet has broken down geographical restrictions, physical restrictions, capital flow restrictions, and communication restrictions. As long as you have a mobile phone, you can play the Qianbao APP. Everyone participates, everyone deposits money, and everyone withdraws money. The number of people involved in the case is said to be in the millions. Relatively speaking, it is still an online pyramid scheme (Ponzi scheme 1.0), every day. The brainwashing cannot be stopped during meetings, and violent and illegal means are used, which is simply too weak. With the rise of blockchain technology, Ponzi schemes empowered by "blockchain+" can no longer be described as becoming more powerful than a tiger. It is simply like a chicken becoming a tiger. Like the Internet, "Blockchain+" technology has truly improved application scenarios. Ponzi schemes have further upgraded on the second generation basis of "Internet+". Because of major breakthroughs in scenario enhancements and improvements, they have become Ponzi Scheme 3.0. , its characteristics are mainly reflected in the following aspects:

1. Decentralization, no leadership. The smart contract of the blockchain runs automatically, does not require human intervention, and cannot be interrupted by humans. Code rules are hard-coded and cannot be tampered with. In terms of scene improvement, it has solved the biggest pain point of Ponzi schemes for thousands of years, that is, the problem of the leader running away. Because the leader is a program and a code, the blockchain program can exist permanently and no one can delete it. I think this is the biggest breakthrough. This virtual leader is always there. He cannot run away, will not run away, and will not change. The rules will never change, and he will adhere to the Ponzi line for one hundred, one thousand, and ten thousand years. Some people may say that smart contracts can be iterated and can also be manipulated to leave backdoors. That's right, but it can also be done without iteration. Even if it is iterated, it will be transparent and visible, and it will be clear at a glance if there is a backdoor. This is the characteristic of blockchain smart contracts. If you cheat on it, it is equivalent to taking out cheat sheets under the nose of the teacher. No one will participate in such a smart contract once it is online. Therefore, after technical review and verification, there are no backdoors, fair rules, and irrevocable smart contracts, which can be implemented using blockchain technology. Such reliability, once verified, remains unchanged forever. This is the certainty of smart contracts. For a program, even one character of the code remains unchanged. If it is run a million or a trillion times, the result will be consistent and deterministic.

2, process transparency. The number of depositors, address account, amount, and time; the number of withdrawals, address account, amount, and time; all are visible. The blockchain has a public ledger function, which can be viewed by everyone around the world, and the ledger data viewed by everyone is exactly the same. Why did Qian Bao lose his position? Because we can't see his backend account, how much money goes in every day, how much money comes out, and the specific details of each transaction. In this way, you can see the evaluation of your redemption ability before depositing money, and the evaluation result is absolutely certain, that is, it will not change after you deposit.

3. Complete anonymity. If you have heard of zero-knowledge proof technology. You can skip this part. To put it simply, many of the things we had in the mathematical knowledge base in the past had no application scenarios after invention. Later, it was discovered that this knowledge is very useful for anonymization. The cryptography technology in the blockchain can effectively achieve identity concealment. As we all know, Zhihu cannot achieve true anonymity in terms of technical structure, but blockchain can.

4. The rules are open and fair to everyone. Deposit one yuan, and withdraw ten yuan as rebate. This rule applies to everyone and will never change. You deposit one dollar, and first withdraw money to the person in front of you, and then the person behind you deposits money, and then withdraws money to you. Fair, right? I have reflected on this many times and think it is still fair.

5. Sustainable iteration. In low-level Ponzi schemes, the leader, product designer, profit distributor, and benefit recipient are often four in one. However, in a blockchain Ponzi scheme, the four roles can be completely logically separated. Achieve sustainable iteration. Through social-based collaboration, these projects can be iterated on forever. There are now 400 senior engineers who are developing around Bitcoin and constantly updating the code. These people don’t need to know anyone. As long as the application is valuable, they can keep iterating. Which centralized project can do this? Even a BAT-level company cannot hire so many professionals scattered around the world. This iterative method of socialization is not affected by changes in a specific person or organization.

Ponzi schemes empowered by "blockchain" use blockchain technology in different scopes, because the technology in this field is still constantly being updated. Applications such as smart contracts are these two The years just add up. The earliest blockchain application is Bitcoin. Some people think that Bitcoin itself has the characteristics of a Ponzi scheme. In 2013, I wrote an answer that implicitly pointed out that this new type of Ponzi scheme will be very lethal because it has the characteristics of a Ponzi scheme. It has the characteristics of no leader, open ledgers, no escape, and open and fair rules. Later, I also discovered that many people around me were more interested in Ponzi schemes than in blockchain technology. Once they hear that Bitcoin is not a Ponzi scheme, they usually walk away silently before I start talking about blockchain technology. On the contrary, if you tell them that it is a Ponzi scheme, they will then ask where to buy it. ? Of course, there is a lot of controversy over whether Bitcoin is a Ponzi scheme, because the actual application scenarios of Bitcoin are constantly expanding.

And in ICIn the O craze, there are a lot of air coins, which are fake Ponzi schemes and have no application scenarios. People who buy these air coins probably know that they are Ponzi schemes, but if they look good in packaging, they buy them. . There are estimated to be hundreds or thousands of such air coins. The scope of the cases involved spans the world, and the amount exceeds tens of billions. These ICOs use smart contracts for subscription and distribution, and then circulate on their own in the secondary market. In this case, withdrawals are not guaranteed, and some people may lose all their money. Many blockchain professionals have always wanted to draw a clear line between these applications, because although these air coins use part of blockchain technology, there is still a centralized organization or individual behind them, with very few network nodes, and users cannot deposit funds. At that time, it was directly aggregated to an organization or individual (and therefore would be swept away). However, there is no doubt that Aircoin still uses the blockchain for deposits and raising funds, which solves part of the problem of running away and increases the scope and scope of the Ponzi scheme. Communication ability. This is what happens objectively.

Since this year, with the advancement of technology, Ponzi schemes that use smart contracts to achieve more decentralization have begun to surface. Deposits and raises are locked using smart contracts to complete a complete closed loop of deposit, subscription and withdrawal. It can already be a very pure blockchain application. There are some blockchain games that can be openly admitted. After their release, they publicly claimed that they were a Ponzi game. He said: Look, the rules are transparent, the code is visible, and the deposit contract is Locked, no escape, no human intervention, automatic withdrawal. Play early and earn early. This is a crucial breakthrough, publicly admitting that you are a Ponzi scheme, which is something that Ponzi schemes 1.0 and 2.0 could not do before (they did not dare to openly admit that you are a Ponzi scheme). incredible. The gameplay is simple and crude.

This solves a major obstacle in the previous Ponzi scheme promotion process. In the past, it relied on brainwashing to win people's heads, but now it relies on code to speak for itself. You see, "This program won't run away on its own, right? There's no backdoor in it, right? Has the leader disappeared? Even if Satoshi Nakamoto is caught, it won't affect the continued execution of the program, right?" So the first batch of blockchain Ponzi schemes fell into the trap, right? What is important are coders who understand the code, and then these coders stand up and say that after technical verification, it is indeed such an effect, driving other people who do not read the code to join.

In addition to Ponzi scheme application scenarios involving entertainment, gambling, and fraud, blockchain also has opportunities to flex its muscles in Ponzi scheme application scenarios involving the national economy and people's livelihood, and public utilities, and can even be used extremely Dadi enhances people's sense of gain and happiness, and actually improves people's lives. For example, the application of national or global public pension platforms based on blockchain. Because this platform is based on blockchain, it can solve several major shortcomings of pension funds:

1. The problem of fund misappropriation. The ledger is open, and the funds are locked in a decentralized manner. No one can unlock it, except recipients who meet the rules and can withdraw funds. No possibility of appropriation.

2. Inflation problem. The current pension system adjusts coefficients every year based on a series of complex algorithms such as inflation. After the adjustment, recipients are often dissatisfied., because the total amount has increased, but the purchasing power has decreased. By taking advantage of the fact that virtual currency cannot be issued additionally, the inflation rate can be restrained and all the money received can be guaranteed to be real money.

3. Unpredictable problems. It is difficult for us to predict the pension withdrawal situation in 30 years, but it can be predicted in advance through smart contracts. Stimulate enthusiasm for payment.

4. Policy loopholes and fairness issues. Any pension policy targets diverse groups and there will be unfair situations. Everyone wants to pay less and get more, pay later and withdraw early. The transparency of the blockchain is down to each account, rather than a set of general policies that plug loopholes in the implementation process. Everyone is the same, pay more and get out more, pay early and get out early. It can even be inherited and never lost.

This greatly reduces the burden and cost of managing pensions by the state. Things that the existing pension system can do can still be done after using blockchain technology, such as state subsidies. Just put money into the contract, and it will be locked. There will be no fakes, such as forced payment, and every record will be true and traceable. All in all, all existing systems and rules can be put on the chain, which improves efficiency and output levels and ensures fairness without affecting the existing effects. Moreover, because the cost of the huge management system is reduced, everyone can receive The absolute number may increase a lot, which will have the effect of actually improving people's lives. Again, it will increase the sense of gain and happiness. In the matter of pensions, the subject of our trust has changed from a single national government to a national government + blockchain, and more than 50% of the process has become a fixed software program. Aren’t we more trusting in this way? If the on-chain pension system is 100% implemented, it can even break the national restrictions and be implemented by a piece of code that is honest, cannot cheat, and cannot be tampered with. Automatic deposits and automatic withdrawals. Trusting it is like trusting a dead person. There will be no mistakes.

The design of the next generation to support this generation is a great invention of our human evolution, which has accelerated the speed of social development. On the surface, it seems that the last generation on earth will suffer more, but in fact it is not. Yes, because the last generation of people on earth may not necessarily know that they are the last generation (maybe they know it in the last few seconds, but so what). What’s more, the earth has disappeared, does the last generation of people still need to withdraw funds for retirement? Obviously, no need.

The biggest disadvantage of a Ponzi scheme is that it runs away midway and the funds are broken. Blockchain has a clear technical solution to solve this problem, and it can also be proven and falsified, so , this technology is scientific. Once the disadvantages are eliminated and the benefits gradually emerge, the Ponzi scheme will achieve greater development in the future.

I also want to ask a question. In human history, are there any things that were originally negative or useless? Later, with the development of technology, the disadvantages were eliminated or avoided, and the functions were discovered. And then become more and more useful and important?

IV How is blockchain applied in the legal field

Using blockchain technology to doThe storage and issuance of electronic evidence is the basis for the application of blockchain technology in the legal field.

Blockchain technology can be used to securely protect electronic data, prevent tampering, and conduct data processing throughout the entire life cycle of electronic data generation, collection, transmission, and storage. Traces of operation.

Use blockchain technology to preserve electronic evidence, record the electronic data that needs to be deposited in the form of transactions, stamp it with a timestamp, and record it in the block, thereby completing the process of data preservation and evidence depositing. process. During the data storage process, multiple participating nodes jointly witness and jointly maintain a distributed ledger, thus greatly reducing the possibility of data loss, tampering, and attack.

The combination of blockchain and electronic data storage can reduce the cost of electronic data storage, facilitate electronic data collection and evidence identification, and improve litigation efficiency.

IV What is the relationship between blockchain and digital renminbi

Blockchain refers to a chain connected by a series of data blocks (i.e. blocks). The connection method is: where The N+1th block contains the hash value of the Nth block. Moreover, such a chain of data blocks is simultaneously stored and maintained by a widely distributed and huge number of server nodes. Each server node has a complete copy of the blockchain.
Digital currency is another form of existence and circulation of legal currency. Compared with the banknotes and coins currently in circulation, it exists in a digital form. The legal existence of digital currency is legal and is based on blockchain technology.
Blockchain is the underlying technology for digital currency issuance. This is also the most direct relationship between the two. They can exist independently of each other.
For reference.

VI What is blockchain

The poster must first understand two 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 can always lead to more success.Lots of 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.

Currently, it is whoever owns the system who keeps the accounts. WeChat’s account books are kept by Tencent, and Taobao’s account books are kept by Alibaba. 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 this way, everyone in the system has 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. It’s 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 earn micro points by inviting friends, and you can also earn points by buying and selling Leitz dogs.In terms of calculus, many people think that raising a dog is not a big deal. It is a bit boring because it does not need to be collected all the time like other platforms. The current Leitz dog is only the 0th generation, and the breeding function may appear in the later period and the 1st generation will be released. generation, second 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 emerge.

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, limited capital, only channel, and the end point is socialist ownership by the whole people. Blockchain, free access to capital, restrictions on 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, one is free access for capital; the other is channelsClearing channel costs leads to happiness. One is that channel costs gradually increase and the economy is driven by investment, which eventually leads to 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 and inhibiting entity 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 Zhang Sanqian in your computerYou gave me 10,000 yuan. Zhang San said that I also recorded in my computer that you owed 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. Like the Internet, 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 need to think about what practical problems we can use this technology to solve. Are there any other problems with these problems?alternative solution. 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 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 will 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.

Thanks for reading.

VII How to do blockchain

It is necessary to establish the data layer, network layer, consensus layer, incentive layer, contract layer and application layer.

1. The data layer encapsulates the underlying data blocks and related data encryption and timestamps and other basic data and basic algorithms;

2. The network layer includes distribution

3. The consensus layer mainly encapsulates various consensus algorithms of network nodes;

4. The incentive layer integrates economic factors Into the blockchain technology system, it mainly includes the issuance mechanism and distribution mechanism of economic incentives;

5. The contract layer mainly encapsulates various scripts, algorithms and smart contracts, which is the programmable feature of the blockchain The basis of;

6The application layer encapsulates various application scenarios and cases of the blockchain.

(7) Extended reading of blockchain on the official website of People’s MOOC

General Secretary Xi Jinping emphasized during the 18th collective study session of the Political Bureau of the CPC Central Committee, “Take blockchain as a core technology An important breakthrough for independent innovation” and “accelerating the development of blockchain technology and industrial innovation”.

The forward-looking judgment of the Party Central Committee has brought "blockchain" into the public eye and has become a common concern for financial capital, the real economy and social public opinion.

From network power to big data, from media convergence to blockchain, the Political Bureau of the CPC Central Committee has collectively studied and aimed at the forefront of technological change, demonstrating the direction, forward-looking judgment and future foresight of the Party Central Committee, leading It follows the pace of China's industrial reform and economic transformation. This collective study by the Political Bureau of the Central Committee specifically emphasized "blockchain", which opened up imagination space for the development and application of blockchain.

From a technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming. From an application perspective, simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency.

These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for the blockchain to create trust. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

Ⅷ What is the relationship between blockchain and digital RMB

Difference:
1. Blockchain and digital currency complement each other and are inseparable. Blockchain is the circulation of digital currency. One of the means.
2. Blockchain is the theoretical basis of digital currency. Digital currency is established on the basis of blockchain technology. Blockchain has certain guarantees for the security of digital currency. At the same time, digital currency is a block chain. The most successful application of chain technology.
Since the concept of "digital renminbi" was proposed, digital renminbi has often been compared to cryptocurrencies such as Bitcoin and Ethereum that use blockchain technology. So let’s first figure out what is digital renminbi?
Digital RMB is a legal currency in digital form issued by the People's Bank of China. It is operated by designated operating agencies and redeemed by the public. It is based on a broad account system and supports the loose coupling function of bank accounts. It is compatible with paper Banknotes and coins are equivalent, have value characteristics and legal compensability, and support controllable anonymity.
The concept of digital renminbi has two key points. One is that digital renminbi is a legal currency in digital form; the other is that it is equivalent to banknotes and coins. Digital renminbi is mainly positioned at M0, which is cash and currency in circulation. coin.
But in fact, the digital renminbi only draws on blockchain technology, but as a legal currency, the digital renminbi has centralized characteristics. Executives from major European central banks said that issuing central bank digital currencies does not actually require the use of blockchain technology.The core elements of the digital RMB system framework are "one currency, two databases, and three centers". The technologies used in the use process include NFC and distributed ledger technology.
02 What is blockchain technology?
In a broad sense, blockchain technology actually uses fast-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.
03 Digital RMB just draws on blockchain technology
Digital RMB has the same characteristics as blockchain technology, such as traceability and non-tamperability. As a legal currency issued by the state, the most important feature of the digital renminbi is the "centralized management model", and one of the core features of the blockchain is "decentralization".
Previously, many countries have issued digital currencies relying on blockchain technology, such as Uruguay, Iran, Senegal, etc., but none of them have become popular.
Executives of major European central banks stated in September 2020: If central banks around the world want to issue digital currencies, they do not actually need to use blockchain technology. Central banks provide central bank digital currencies. "Trust", so after the central bank intervenes, there is no need to use blockchain technology.
In the financial field, currently blockchain technology has received corresponding experimental and small-scale applications in digital currency, payment and settlement, digital bills, etc.
04 “One coin, two treasury, three centers”
As mentioned earlier, the core elements of the digital RMB system framework are “one currency, two treasury, three centers”. Here we will briefly explain “one coin, two treasury, three centers”. Two warehouses, three centers.” The “one currency” here actually refers to the central bank’s digital currency; the “two databases” refer to the digital currency issuance database (the database that stores the central bank’s digital currency issuance fund) and the digital currency bank database (the database where commercial banks store the central bank’s digital currency); The “three centers” refer to the certification center (responsible for identity information management), registration center (responsible for digital currency ownership registration) and big data issuance center (responsible for analysis of anti-money laundering, payment behavior, etc.).

Ⅸ People's Daily Online invited the general manager of Beijing Yumede to be a guest to discuss blockchain applications and cooperation

On July 15, 2022, Beijing Yumede Intellectual Property Service Co., Ltd. ( (hereinafter referred to as "Beijing Entertainment Virtue") General Manager Xu Tingxu and his party were invited by People's Daily to visit the New Media Building of People's Daily. People's Kaihui Fiber Network Lingjing·People's Art Museum CEO Yang Cheng also attended the exchange event and discussed relevant cooperation with Xu Tingxu Conducted in-depth discussions. Xu Tingxu also introduced the development plan of Yumeide and the development status of the "Legend" game.
(Xu Tingxu, general manager of Beijing Yumede, was invited to be a guest at People's Daily Online)
Xu Tingxu introduced the development history of Yumede. Yumede was established in 2000 and completed the famous online game in the same year.The development of the game "Legend". Since the game "Legend" was introduced to China in 2001, its popularity has never diminished. It has developed from a game to an IP, and Yumeide has also developed into a multinational company, with its business covering games. Development, distribution, investment, blockchain, etc.
Yumeide has also continued to develop some follow-up products of Legend. In 2020, "Legend 4" was launched in South Korea, triggering a craze; after the international version of "Legend 4" was launched last year, the highest number of people online at the same time worldwide exceeded 1.5 million, which is When "Legend of Blood" was at its peak in China, there were almost three times the number of people online at the same time. Xu Tingxu said that the main reason why the international version of "Legend 4" is so successful is that it is combined with blockchain technology. The international version of "Legend 4" has launched character NFTs and has also turned some major in-game assets into NFTs. Yumeide provides a special platform where NFT digital cards can be uploaded for the convenience of players.
The success of the international version of "Legend 4" has also allowed Yumede to accelerate the pace of improving its metaverse plan. Yumede has launched a new blockchain game platform Wemixplay, and hopes that it can become a global game company. The backbone of the service-based ecosystem for blockchain games. Yumeide recently added 9 games to the Wemixplay blockchain game platform, which allows developers to launch blockchain games without knowing much about Web3 and brings game developers and players closer through decentralization connected together. Yumeide hopes to have 100 games launched on Wemixplay by the end of 2022. In addition to focusing on the development and application of blockchain technology, Yumeide has also made 22 investments in blockchain projects around the world this year.
When talking about the field of blockchain, Yang Cheng not only introduced Lingjing·People's Art Museum, but also put forward suggestions for cooperation with Yumeide. Lingjing·People's Art Museum was officially launched by People's Daily Online in January this year, aiming to provide a digital platform for artists and outstanding works of art, and provide services for digital copyright protection of artworks, digital publishing, digital transformation, digital certification (blockchain), etc. , using digital technology to serve popular art. The digital collection issuance of Lingjing·People's Art Museum will focus on the fields of art, performance, film and television, and public welfare. It will also try to distribute digital collections related to Chinese culture overseas to open up a new path for Chinese culture to go global and explore Chinese culture. New forms of overseas communication have allowed China’s excellent traditional culture to become an important source of literary and artistic innovation with the help of new technological means.
(Lingjing·People's Art Museum is online)
"Legendary" is a familiar IP, whether it is story or character art, etc., there are many areas worthy of development, and "Legendary" IP is also closely related to Lingjing·People's Art The theme of the museum is highly consistent. In the future, Yumeide can authorize Lingjing·People's Art Museum, and then Lingjing·People's Art Museum will digitize the relevant results of the "Legendary" IP, and then develop related derivatives to enrich the platform's work library, and the development of such products At the same time, it can attract morePeople pay attention to the story and scenes of the game, and even become new game players, forming a complete chain of mutual promotion. The two parties have also developed more ideas about possible in-depth cooperation, which is also worth looking forward to.
After years of development, China’s domestic game market has risen rapidly, and competition has become increasingly fierce. For Chinese game companies, it is urgent to go global. Over the years, Yumede has also been hoping to use its rich publishing experience to help China's small and medium-sized game companies go global and support more game works to go global. As the company with the most successful blockchain games currently, more than 30 games have been launched on Wemixplay, the Yumeide blockchain game platform. Xu Tingxu hopes that in the future, games developed by Chinese companies will be launched through the Wemixplay platform, making it easier to Enter the global market and embark on a new development path.
Xu Tingxu said that for Yumede, the Chinese game market is the most important market. Yumede has also planned a number of measures to support Chinese game manufacturers, hoping to bring vitality to the majority of small and medium-sized enterprises and maximize the IP value of the game industry. , game operations and other aspects to create new ideas. In addition, Yumede also actively participates in projects that are beneficial to China's social and cultural development and grows together with Chinese companies. Yumede's goal is to become a cooperative body that can coexist and prosper with most Chinese game companies.
(Xu Tingxu, general manager of Beijing Yumeide, visited the development history of People's Daily)
The "Legend" game has achieved great success in China, with many users and a huge volume. The huge profits brought by the Legend game market have also led to piracy There are endless infringement phenomena. As a game development company, Yumede has always attached great importance to the protection of intellectual property rights. Yumede has adopted a multi-pronged approach through prosecution, complaints and reports, and jointly with local governments, and has achieved good results in safeguarding rights. So far, Yumede has won more than 20 cases, and more than 3,000 legendary infringing games have been removed from the shelves.
Xu Tingxu introduced that after obtaining the authorization to maintain the intellectual property rights of the "Legend of Legend" work within mainland China, Beijing Yumeide actively carried out rights protection activities and cooperated with the public security organs and relevant departments to fight against infringements involving the "Legend" game. The behavior was severely punished. From now on, all business related to the "Legend" IP, including rights confirmation and authorization, will be completed by Beijing Yumeide.
The success and value of "Legendary" IP are a reflection of Yumede's R&D strength. Yumede's exploration and practice in the field of blockchain also present more possibilities for the development of games and other industries. I believe People.com We can establish in-depth cooperation with Yumede based on the "Legendary" IP, develop more forms of excellent works, and explore and create new development directions in the cultural field.
