① How to view the central bank’s issuance of blockchain-based legal digital currency

The trial operation platform is owned by the central bank, and this platform is not currently open, it is only a successful test. These electronic currencies used for testing by the central bank may be legally legal currency, but they have not yet left the central bank's door. Therefore, the word "release" in the news headline is very loose, and it is the material that all kinds of ghosts and ghosts are most looking forward to. One of the impacts is that various people have begun to endorse the so-called central bank and create a new wave of attention-grabbing ‘news’. The impact on Bitcoin is that countless analyzes and speculations advocating for ups and downs are coming in again.

China Securities News: Is blockchain technology suitable for digital currency?

Li Wei: In recent years, blockchain technology has gradually received close attention from the financial industry at home and abroad. Central banks, commercial banks, and Internet companies in some countries have actively explored blockchain technology and its application in the financial field. application. Digital currency involves distributed architecture, cryptography technology, security chips, mobile payments, trusted computing and other technologies. Blockchain technology is only one of the optional implementation technologies for digital currencies. Whether it will be used in digital currency in the future depends on whether the shortcomings of blockchain technology in network security, business processing performance, transaction consistency, etc. can be solved. It also depends on the unremitting efforts of all parties in industry, academia, and research in terms of its technical system, application framework, etc. Explore and perfect. To this end, the People's Bank of China chose to build a blockchain technology application prototype system in the bill business scenario in 2016, actively organizing all parties to study its technological maturity and business adaptability, and verify its feasibility of large-scale application in the financial industry. The meaning of this expression in the interview is: there are still unresolved shortcomings in the current application of blockchain technology. With our party’s governance style in recent years, we will not [issue] something with such shortcomings that need to be resolved.

Summary: On February 5, 2017, the day the question was answered, the Central Bank of China was not the first central bank in the world to issue and apply digital currency.

② Does blockchain really have development prospects?

Blockchain undoubtedly has development prospects, and the necessary conditions for development prospects are Enter the mainstream market.

Matt Spoke, founder and CEO of North American blockchain infrastructure The OAN (formerly Aion Network), published an article in Forbes on July 24 titled "In order to successfully enter the mainstream market, blockchain projects must "Eat Dog Food", in which Matt mentioned his views on how blockchain should enter the mainstream market - "Eat Dog Food".

In the technology circle, there is a jargon called "dogfooding" (also known as eating your own dog food), which refers to a company using its own products and becoming a user of its own products. Many high-growth companies (such as Microsoft, Facebook, Amazon, Apple, Netflix and Google) also use dog food to test products or help build credibility for their products.. Although "eating dog food" is often used to find and fix bugs, it has another value: creating reliable use cases for the company's products.

This is worth learning from blockchain projects, because blockchain projects often hold the idea of ​​"if it is built, they (users) will naturally come" and habitually create new and interesting things. Responsibility for blockchain applications is given to third parties.

This attitude is so common that even the well-known blockchain summit Consensus 2019 (2019 Consensus Conference) also held a conference titled "Build it, they (users) will naturally come: Creating a global area" Blockchain Center's roundtable forum discusses how governments around the world can make efforts to attract blockchain projects while balancing regulatory, investment and innovation needs.

To be fair, this strategy may be effective for blockchains that only target cryptocurrency circles. For security tokens, especially exchanges that trade such representatives, this makes even more sense - "supply creates demand" is the usual thinking here, especially considering the complex infrastructure required to implement these transactions. .

In contrast, "eating dog food" is more likely to be used by blockchain project developers seeking mainstream audiences (such as those in the financial industry, manufacturing and supply chain, identity management, etc.) use. If blockchain technology wants to break into these mainstream fields, blockchain companies must first "eat dog food." This will not only clearly prove that blockchain technology is feasible outside the currency circle, but also highlight that blockchain can not only optimize existing use cases, but also create new use cases.

The OAN team has always adhered to this concept and relied on the technology stacks of The OAN and Aion built over the years to develop Moves, a financial technology platform for independent workers.

Matt said that when developing the Moves product, the team hopes that the relevant functions of The OAN blockchain network can be fully utilized, so the focus will be on the following three aspects:

1. How to use The OAN blockchain network to improve the credit efficiency of products.

There are two main considerations for improving credit efficiency: 1) Can Zheng Lu learn from the mechanisms of the DeFi market to reduce capital costs; 2) Can blockchain technology be used to increase the external credit process for Moves? of trust. Here, Moves will form a "pooling of wisdom" mechanism, allowing everyone to contribute to reducing credit risks and increasing the credibility of the credit granting process, and may even develop a micro-guarantee mechanism in the future. Therefore, users will be able to participate in the market established by the platform as a borrower, lender or guarantor.

2. How to align the interests of products and users.

Specifically, by connecting Moves to The OAN network, and with the help of the digital asset Aion, a relationship of aligned interests is formed between the product and the user, so that the user canYou can personally experience the success of Moves product development, and you can also directly participate in the blockchain network that supports Moves - The OAN.

3. How to create a pioneering financial reputation data open system with Moves.

This open system may become a replacement for traditional credit scores or related mechanisms. For years, banks and financial institutions have used scores from Equifax, FICO or others as risk indicators, and the Moves team believes the product it is building will be a good start - a better, more modern financial system. The beginning of the reputation system. This is a long-term goal.

Moves supports mainstream ride-sharing, food delivery and other gig economy concept platforms in North America and will be the flagship open application developed by The OAN on its blockchain network. In June, Moves' business operations expanded from Ontario to two more provinces - Alberta and British Columbia, and into Western Canada.

The various measures taken by The OAN team are all based on the spirit of "eating dog food" and working hard to allow blockchain technology to enter the mainstream market as soon as possible. Blockchain is not for the niche, but for the mainstream. In addition to The OAN team, many projects and institutions in the blockchain industry are also moving towards this goal. With such an excellent and targeted blockchain, what can you do? Are you saying there is no development prospect?

③ How to query blockchain coins on Ethereum

You can directly query by entering information such as wallet address, transaction ID, block hash or block height, which is very convenient.
If you are querying account balance, historical transaction data of the account and other information, it is recommended to directly enter the wallet address to query; if you are querying relevant information of a certain transfer, such as whether it has been received and how the progress is, it is most convenient to enter the transaction ID.
Of course, the blockchain browser can not only query your own account, but also other people's accounts and related transaction information, including the account of Bitcoin founder Satoshi Nakamoto.

④ Economic functional shortcomings of blockchain digital currency

Issuing digital currency based on blockchain is also called decentralized currency issuance. It is generally recognized in the chain circle that this can combat the abuse of centralization. Inflation caused by money issuance. Including Satoshi Nakamoto also expressed his distrust of centralized money printing in the Bitcoin genesis block.

During the global financial crisis in 2008, Satoshi Nakamoto announced Bitcoin to the world. When introducing his innovation, he said: "The most fundamental problem with traditional currency is trust. The central bank must make people trust it. It will not devalue the currency, but this credibility has never existed in history. Banks must be trusted to manage money and circulate this wealth in the form of electronic currency, but banks use currency to create credit bubbles, making Private wealth shrinks."

On January 3, 2009, Satoshi Nakamoto released the first version of the open source Bitcoin client, announcing the birth of Bitcoin. Satoshi Nakamoto wrote in the genesis block: “On January 3, 2009, the Chancellor was on the verge of implementing a second round of bank bailouts.”

Judging from the operating practices of Bitcoin and Ethereum, digital currencies based on blockchain technology can indeed resist inflation, because each incremental coin of the digital currency is generated through mining (PoW, The emergence of proof of work corresponds to undifferentiated human (machine) labor. There is no centralized organization that can bypass mining labor and issue currencies on a large scale.

However, this decentralized currency issuance mechanism has a natural economic flaw: it cannot dynamically adjust the amount of currency issuance according to the growth of wealth on the blockchain. When wealth grows faster than Currency issuance will create a deflationary situation, that is, there will not be enough new digital currencies to match the growth of wealth on the blockchain.

We illustrate the shortcomings of the decentralized blockchain currency issuance mechanism by comparing it with the traditional centralized currency issuance mechanism.

In RMB, under the centralized currency issuance mechanism, there are three main ways to add new currency issuance:

1. Earning foreign exchange through exports leads to the investment of foreign exchange reserves. Buy domestically produced goods abroad to obtain U.S. dollars, and then settle the U.S. dollars to obtain RMB for circulation into the market. The country uses U.S. dollars to purchase bulk commodities overseas. In this process, the newly added wealth is commodities, and the corresponding RMB is invested in the foreign exchange account.

2. Bank loan. The developer built the house, the individual bought the house with a mortgage loan from the bank, and worked hard to repay the loan. In this process, the newly added wealth is a house, and the corresponding RMB investment is a loan. In the end, individuals realize wealth through labor and repay the loan.

3. Bank interest. Depositing money in the bank will earn interest, and the interest rate corresponds to the economic growth rate. In this process, economic growth means wealth growth, and the corresponding RMB investment is deposit interest.

In the above three methods, the newly increased wealth is matched by the new currency, so there is a sufficient amount of currency in the market chasing a sufficient amount of wealth, and the currency value is stable.

Let’s look at the currency issuance of blockchain.

Obtain incremental digital currency through the labor of mining and accounting. In this process, wealth growth is due to the mining of blocks and decentralized ledger maintenance, corresponding to the issuance of new digital currencies. However, the generation of wealth on the blockchain is not limited to mining, but also business cooperation through smart contracts, as well as the creation of native digital artworks NFT, etc. These newly generated wealth do not have corresponding digital currency issuance.

We use NFT to illustrate. An artist creates an art work in the metaverse where the blockchain is located. If this work is auctioned off-chain, it can reach 1million US dollars, and after this work was put on the blockchain, the wealth on the entire blockchain increased by 1 million US dollars, but no corresponding digital currency was generated. If this occurs under a centralized currency issuance mechanism, the corresponding currency delivery can be obtained through the above methods 1 and 2. Assume that 100 NFT works are produced within a year, and these works are valued at 100 million US dollars off the chain, but there is no digital currency corresponding to this 100 million US dollars of wealth on the chain.

Since NFT can only be traded through digital currency on the chain, the price of digital currency has increased. When there is more and more NFT wealth on the blockchain, and the growth rate exceeds the currency release speed of mining, then the price of the digital currency corresponding to NFT will become lower and lower, and at the same time, the off-chain dollar price corresponding to the digital currency will decrease. Higher and higher. In this way, deflation occurs on the blockchain. If it continues to develop, the digital currency generated by mining may eventually be able to buy an NFT with an off-chain valuation of US$1 million.

So, is mining valuable or digital art creation valuable? Bitcoin has already seen this strange phenomenon. One Bitcoin obtained from a high-carbon, uncreative mining job can be equivalent to a year's salary income of an ordinary white-collar worker in China.

The economic ecology of the Metaverse is based on blockchain technology, so what kind of economic crisis will this flaw bring to the Metaverse?

To be continued...

⑤ Teach you step by step how to issue tokens

Currently, the most widely used token (blockchain currency) is in ERC20 token issued on Ethereum. ERC20 can be regarded as a smart contract. This smart contract keeps track of who owns how many tokens and includes some token transfer functions. If the token smart contract you write complies with the ERC20 standard, your token is called an ERC20 token.

Many concepts similar to ERC20 can seem complicated when you just listen to people talking about them. In fact, the easiest way to understand is to implement it yourself.

An ERC20 token is a smart contract, which records account token balance data and method functions for transferring tokens. Smart contracts can be tested in a test environment before deploying them on Ethereum. There are some Ethereum test networks available. We chose the Rinkeby network for this currency issuance experiment.
1. In the metemask wallet of Chrome browser, select the rinkeby test network.

Send a Post on Facebook, the content is the currency receiving address, which is the account address of the metamask wallet. The post is set to public. Right-click the posting time, copy the link, and fill in Rinkeby Faucet in. Choose to borrow 3 ETH, the usage period is 8 hours, and you can get the 3 ETH after waiting for a while.

You can also see that the ETH has arrived in the metamask wallet.

3. Now that we have the money and wallet, let’s start writing the currency issuance smart contract. We choose the Remix online development platform. There are a lot of cases for ERC20 tokens that you can refer to, just borrow them.

After compiling the smart contract, Run it to fly.

Here you need to fill in some configuration information. Select "Web3" for the Environment running environment because we are using the metamask wallet; fill in the metamask wallet account for the Account account; fill in the upper limit of the Gas limit transaction fee. It doesn't matter if you fill in more for this. No real fees are consumed in the test network; the Value contract transfer amount, here is 0Wei; select the HayekToken smart contract; fill in the currency information (input parameters of the contract constructor), the number of coins is 21,000,000 (the same as Bitcoin, pay tribute to Satoshi Nakamoto ), currency name HayekToken, minimum currency unit 0 (decimaUnits), currency abbreviation HYT.
After filling in the configuration information, click "Create" and the contract will start running. Then the metamask wallet pops up, requiring us to confirm the "transaction" and click "Submit".

4. Verification
After the smart contract was released, the smart contract address appeared in Remix:
You can also check the account balance. Note that you must add "" when entering the account, and click "balanceOf ”

You can see 21 million HYT in my account.

Add Token to the metamask wallet and you can also see the token.

Coin issuance successful!

Blockchain token issuance is very simple. How is it different from other tokens, such as Q coins?

Tokens act as a circulation medium in a proprietary field. Q coins can be used to purchase Tencent's virtual services, game coins can be used to catch dolls, and cafeteria menus can be used to buy food. What is the difference between ordinary tokens (Q coins, game coins, menu cards) and blockchain tokens (ERC20)? The core difference is actually not the difference between centralization and decentralization, but the difference between whether it can be freely exchanged. Q coins can only be recharged with legal tender on Tencent's platform, but Q coins cannot be exchanged for legal tender. Game coins can only be used to catch dolls, not to buy snacks. Menu cards can only be used in the cafeteria. Blockchain tokens can be exchanged for another token on the exchange, and can also be exchanged for legal currency over the counter.

This difference makes a huge difference. Blockchain tokens can be traded freely, forming a trading market with fluctuations and financial attributes. Scams such as banker coins and pyramid schemes use the financial properties of blockchain tokens to make money. In order to protect small investors (non-qualified investors), various countries have adopted varying degrees of supervision on blockchain tokens.

These analogies are actually very inaccurate, because with the introduction of blockchain tokens and incentive mechanisms, investors and users are integrated in these applications. That is to say, after the introduction of token incentives, holders of tokens will become shareholders. Of course, shareholders hope that this application will be widely popularized, and even contribute to the application, and they will receive benefits when the tokens appreciate. At the same time, token holders are also users and can use tokens to purchase application services or even rent tokens to others. This makes applications that introduce token incentives completely different from ordinary applications. Although ordinary applications may also have point rewards, points cannot be freely circulated and cannot be exchanged for money at will.

New production relationships based on blockchain tokens are being created. You can also try sending a token.

⑥ It is enough to read this article on how to issue tokens in blockchain projects

Everyone has different understanding and usage of Token. We usually think in terms of blockchain technology.

Token, in the initial stage of blockchain development, you can simply understand Token as "points" or "virtual currency" in real life

such as gas stations Car wash shop membership card points, the barber shop downstairs allows you to get it

Spend 2,000 to get a 1,000 hairdressing membership card, the kindergarten teacher gives the little red flowers to the children... Mainly for motivation

A virtual currency of the Lord that is generally recognized within a certain range. You can use the
Token I gave you at that time to replace some of my items or equivalent currency. .

After the emergence of Ethereum ERC20, Token entered the second stage. As a voucher for raising Ether coins, it can be found at

Exchange transactions to automate the ICO process.

After the birth of the translation of token, our understanding of Token has entered the third stage. The connotation of Token has been further

expanded. Token is no longer limited to tokens or ICO tokens, but also has usage rights, income rights, etc.

Attributes, areas Blockchain encryption technology can ensure that all symbols that cannot be tampered with can be used as tokens, that is, they have exclusive use rights. When their exclusive use rights are placed in the value network, they are converted into general use rights. , can

further circulate; that is, only at this stage can the development of the Token economy be possible.

Now, the development stage of domestic Token is generally in the second stage. The primary market of virtual currency has been ruined, and many people are rushing to launch blockchain. For projects, find talents, build a team, write a blockchain project white paper, find

industry leaders’ platforms, do community activities, form a community, and then go to the exchange to issue your own token. It only takes 0.2 ETH to make a token

. After it is issued on the exchange, as long as enough people subscribe for your Token, it will instantly become

thousands With ETH, leeks can be easily harvested.

Warm reminder: Coin issuance itself is not a financing act, and the currency can simply be used as a loop within the project ecology

. Only public ICO after the issuance of coins is a financing activity. Our country clearly prohibits ICO.

Issuance of currency for financing (ICO) is already illegal.

So, what are the specific procedures for issuing coins? Today I will bring you some useful information! Teach you how to use smart contracts

to issue your own virtual currency, which is Token.

Now it is relatively easy for us to issue a currency. This is all thanks to the ERC20 protocol. As one of Ethereum's

protocols, it stipulates the basic structure of the token contract. Any token that complies with the ERC20 protocol can be used in other applications (wallets, exchanges, etc.). With the ERC20 protocol, we do not need to repeatedly develop tokens

Basic functions greatly reduce the threshold for token development, allowing developers to apply tokens to more fields and develop
>
Start more ICO projects; more conveniently, due to different ERC20The tokens are compatible with the ERC20 protocol, so

transactions between two ERC20 tokens can be carried out.

⑦ How to identify the real blockchain digital currency

Whether a certain digital currency is a valuable currency is basically in the "angel round" stage at present. There are three judgment criteria, one is the team, the other is the economic model, and the third is industry demand.

The randomness of the team is too great and will not be discussed here. This article first conducts a detailed analysis of the economic model of digital currency. In subsequent articles, the author will analyze some digital currencies according to different industries.

Strictly speaking, the economic model involved in this article is not completely equivalent to the concepts described in economics. Specifically refers to the consensus mechanism and incentive mechanism of currency in digital currency.

1. Consensus Mechanism

The consensus mechanism is the strategy and method for each node in the blockchain system to reach agreement, and should be flexibly selected according to the system type and application scenarios.

Commonly used consensus mechanisms mainly include PoW, PoS, DPoS, PBFT (and their variants), etc. In addition, based on the different application scenarios of blockchain technology and the characteristics of various consensus mechanisms, this article evaluates the technical level of various consensus mechanisms according to the following dimensions:

a) Compliance supervision: whether it supports Super The authority node supervises the nodes and data of the entire network;

b) Performance efficiency: the efficiency of the transaction reaching consensus and being confirmed;

c) Resource consumption: the CPU, Network input, output, storage and other computer resources;

d) Fault tolerance: the ability to prevent attacks and fraud.

1 Industry background

Find industry pain points: Asset management requires a professional team and knowledge, but most digital currency investors now do not have it; digital The currency market fluctuates greatly, and investors are unable to preserve the value of their assets when the market falls.

2 Own advantages

Having been deeply involved in the stock and futures markets for many years, it has a mature and high-quality asset management team; the AI ​​big data team has strong technical strength.

3 Market Research

After conducting market research, it is estimated that the market value of asset management will be approximately US$1 billion in the next five years.

4 Total amount of digital currency

After considering the expected market value of asset management, development cycle and difficulty, consider issuing 2 billion digital currency XT based on Ethereum ERC20, and will never issue more .

5 Distribution method

Early investors hold 10%, the team holds 20%, business operations 10%, community construction 10%, and investors hold 50%.

6 Digital Currency Release/Repurchase Mechanism

The release mechanism is divided into three categories:

Category 1: The currency holding part for business operations is fully unlocked, and the purpose Restricted to businessand operational activities;

The second category: the release mechanism of the community construction part is that community members release exclusive information, cooperation platforms release exclusive project progress and other behaviors, and based on the number of participating IDs, the corresponding proportion of XT (publisher and participants each receive 50%) until all releases are completed (after the releases are completed, subsequent rewards come from the platform profit pool);

The third category: investors hold mainstream digital currencies and invest in assets on the platform Management, according to the exchange ratio, releases a certain amount of XT, and the early investors and the team hold part of it simultaneously, and unlock it in proportion;

The repurchase mechanism is: 50% of the profit (calculated in XT) is returned to Token holders; the remainder will enter the platform’s profit pool, and 50% of the XT in the profit pool will be destroyed on a monthly basis until the total amount of XT reaches 1 billion; the remainder will be used as platform ecological construction funds;

7 Numbers Monetary rights and interests

Profit sharing: Holding XT is a platform user and can enjoy 50% of the platform's profits;

Platform governance: Participate in platform activities and enjoy XT rewards and other project parties Airdrop activities;

Function customization: Based on the platform's AI big data, investors can purchase services optimized for personal trading strategies

⑧ How to know the issuance of new blockchain coins< /p>

1. Go to coinlist from time to time to check out new coins

2. Go to medium from time to time and search for ido, public sale, whitelist, etc. to get the latest information on new coins
< br>3. There are also pancakeswap ifo, polkastarter, bsclauch and other new projects to pay attention to

4. Of course, Twitter and Telegram should also be fully used

5. You can also pay attention to dextools top10, some new projects often appear in it
Extended information:
Virtual currency refers to non-real currency. Well-known virtual currencies include Internet coins of Internet companies, Q coins of Tencent, Q points, point coupons of Shanda, micro coins launched by Sina (used for micro games, Sina reading, etc.), Chivalrous Yuanbao (used for Chivalrous Road games) ), Pattern Silver (used in Bixueqingtian game), the popular digital currencies in 2013 include Bitcoin, Litecoin, Infinity Coin, Quark Coin, Zeta Coin, Barbeque Coin, Penny Coin (external network), invisible gold bars, Red coins, prime coins. There are hundreds of digital currencies issued around the world. The legends of "Bit Gold, Lite Silver, Infinite Copper, and Penny Aluminum" are popular in the industry.
Currency Concept
There are many different views on the concept of virtual currency. The main representative views are the following three:
1. The theory of virtual exchange tools. Virtual currencies are defined as virtual exchange tools in online games and have no other uses or functions. This statement was adopted in the "Notice of the Ministry of Culture and the Ministry of Commerce on Strengthening the Management of Virtual Currency in Online Games" issued by the Ministry of Culture on June 4, 2009.
2. The theory of partial functions of currency. Virtual currency has some functions of real currency and is similar to currency but not currency. Some scholars divide virtual currency into three stages: primary virtual currency, hard currency primary virtual currency and advanced virtual currency. In the first stage, virtual currencies are issued by non-financial institutions and circulate among a small range of merchants and holders with the help of computer networks; in the second stage, the circulation area expands to all merchants that accept primary virtual currencies; in the ideal third In the first stage, the virtual currency is issued by the central bank or a specific financial institution, and the virtual currency becomes a legal currency that can be circulated in the virtual world. Current virtual currencies are only in their infancy.
3. Digital currency theory. Virtual currency is established based on mathematical algorithms and does not require the intervention of third-party credit institutions. It can be used by any agreed participant and can perform multiple currency functions in the online virtual space. For example, some scholars believe that digital currency is developed based on computer technology, uses strict mathematical algorithms or encryption technology to ensure security and exclusivity, circulates among virtual community members without supervision, and does not use physical media as a carrier.
