Ⅰ What is blockchain and how to make money with blockchain

Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
The ways to make money in the blockchain are as follows:
1. Coin speculation. Coin speculation is like stock speculation. Coin speculation is the lowest threshold for making money in the blockchain;
2. Vendors, district Blockchain is a global market. Like small traders, you can move from a low-price platform to a high-price platform to sell and earn the price difference;
3. Earn commissions for promotion. The blockchain method is to register first Exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you can get a commission;
4. Mining, "mining" in Bitcoin is The accounting process;
5. Technical support, providing blockchain technical support to some teams and enterprises;
6. Opening a trading website and charging handling fees;
7. Developing wallets and wallets It is the infrastructure of the blockchain, just like the "Alipay" or "WeChat Pay" of the blockchain;
8. Be a blockchain project or infrastructure equipment supplier.

Warm reminder: The above explanation is for reference only and does not make any suggestions. There are risks in entering the market, so investment needs to be cautious. Before making any investment, you should ensure that you fully understand the investment nature of the product and the risks involved.

Ⅱ 108 basic knowledge about blockchain Click

108 essential knowledge points for getting started with blockchain

(Welcome to communicate with fans)

1. What is blockchain

< p> Pack the information of multiple transactions and the information indicating the block together. The verified package is the block.

Each block stores the hash value of the previous block, creating a relationship between blocks, that is to say, a chain. Together they are called blockchain.

2. What is Bitcoin

The concept of Bitcoin was proposed by Satoshi Nakamoto in 2009, with a total supply of 21000,000. The Bitcoin chain generates a block approximately every 10 minutes, and this block is mined by miners for 10 minutes. As a reward to miners, a certain number of Bitcoins will be issued to miners, but this certain number is halved every four years. Now it's 12.5. If this continues, all Bitcoins will be available in 2040.

3. What is Ethereum

The biggest difference between Ethereum and Bitcoin is the smart contract. This allows developers to develop and run various applications on it.

4. Distributed ledger

It is a database that is shared, replicated and synchronized among network members. To put it bluntly, all users on the blockchain have accounting functions and the content is consistent, which ensures that the data cannot be tampered with.

5. What is quasi-anonymity?

I believe everyone has a wallet, and the wallet address (a string of characters) used to send transactions is quasi-anonymity.

6． What is open transparency/traceability

The blockchain stores all data from history to the present, anyone can view it, and can also view any data in history.

7. What is tamper-proof

Historical data and current transaction data cannot be tampered with. The data is stored in the block on the chain and has a hash value. If the block information is modified, its hash value will also change, and the hash values ​​of all blocks following it must also be modified to form a new chain. At the same time, the main chain is still conducting transactions to generate blocks. The modified chain must always generate blocks synchronously with the main chain to ensure that the length of the chain is the same. The cost is too high, just to modify a piece of data.

8. What is anti-DDoS attack

DDoS: Hackers control many people’s computers or mobile phones and allow them to access a website at the same time. Since the bandwidth of the server is limited, a large amount of traffic The influx of data may cause the website to fail to function properly, resulting in losses. However, the blockchain is distributed and there is no central server. If one node fails, other nodes will not be affected. Theoretically, if more than 51% of the nodes are attacked, problems will occur.

9. Definition of main chain

Taking Bitcoin as an example, at a certain point in time, a block is mined by two miners at the same time, and then 6 blocks are generated first. The chain of blocks is the main chain

10. Single chain/multi-chain

Single chain refers to the data structure that handles everything on one chain. The core essence of the multi-chain structure is composed of public chain + N sub-chains. There is only one, but in theory there can be countless sub-chains, and each sub-chain can run one or more DAPP systems

11. Public chain/alliance chain/private chain

Public chain:Everyone can participate in the blockchain

Alliance chain: only alliance members are allowed to participate in accounting and query

Private chain: writing and viewing permissions are only in the hands of one organization inside.

12. Consensus layer, data layer, etc.

There are six overall structures of the blockchain: data layer, network layer, consensus layer, incentive layer, contract layer, and application layer. Data layer: a layer that records data, belonging to the underlying technology; network layer: a structure for building a blockchain network, which determines how users are organized. Consensus layer: Provides a set of rules to allow everyone to reach agreement on the information received and stored. Incentive layer: Design incentive policies to encourage users to participate in the blockchain ecosystem; Contract layer: Generally referred to as "smart contracts", it is a set of contract systems that can be automatically executed and written according to their own needs. Application layer: Applications on the blockchain, similar to mobile apps. Former Distributed Storage R&D Center

13. Timestamp

The timestamp refers to the time from January 1, 1970 Day 0 hours 0 minutes 0 seconds 0... The total number of seconds from the current time to now, or the total number of nanoseconds and other very large numbers. Each block is generated with a timestamp indicating when the block was generated.

14. Block/block header/block body

Block is the basic unit of blockchain, and block header and block body are components of blockchain. The information contained in the block header includes the hash of the previous block, the hash of this block, timestamp, etc. The block body is the detailed data in the block.

15. Merkle tree

Merkle tree, also called binary tree, is a data structure for storing data. The bottom layer is the original data contained in all blocks, and the upper layer is each The hash value of a block, the hash of this layer is combined in pairs to generate a new hash value, forming a new layer, and then upwards layer by layer, until a hash value is generated. Such a structure can be used to quickly compare large amounts of data, and you can quickly find the bottom-level historical data you want without downloading all the data.

16. What is expansion?

The size of a Bitcoin block is about 1M and can save 4,000 transaction records. Expansion means making the block larger so that more data can be stored.

17. What is a chain?

Each block will save the hash of the previous block, creating a relationship between the blocks. This relationship is a chain. Data such as block transaction records and status changes are stored through this chain.

18. Block height

This is not the height mentioned in terms of distance. It refers to the total number of blocks between the block and the first block on the chain. This height indicates which block it is, and is just for identification purposes.

19. Fork

Two blocks were generated at the same time (the transaction information in the block is the same, but the hash value of the block is different), and then in Two chains are forked from these two blocks. Whoever generates 6 blocks from these two links first will be the main chain, and the other chain will be discarded.

20. Ghost Protocol

Mining pools with high computing power can easily generate blocks faster than mining machines with low computing power, resulting in most of the blocks on the blockchain being generated by these mining pools with high computing power. However, the blocks generated by mining machines with low computing power are not stored on the chain because they are slow, and these blocks will be invalid.

The ghost protocol allows blocks that should be invalidated to remain on the chain for a short time, and can also be used as part of the proof of work

. In this way, miners with small computing power will contribute more to the main chain, and large mining pools will not be able to monopolize the confirmation of new blocks.

21. Orphan blocks

As mentioned before, orphan blocks are blocks generated at the same time. One of them forms a chain, and the other does not form a chain. Then this block that does not form a chain is called an orphan block.

22. Uncle block

The orphan block mentioned above, through the ghost protocol, makes it part of the proof of work, then it will not be discarded and will be saved in the main chain superior. This block is next

23 replay attack

The hacker resends the message that has been sent to the server. Sometimes this can defraud the server of multiple responses.

24. Directed acyclic graph

Also called data set DAG (directed acyclic graph), DAG is an ideal multi-chain data structure. Most of the blockchains mentioned now are single chains, that is, one block is connected to another block, and DAG is multiple blocks connected. The advantage is that several blocks can be generated at the same time, so the network can process a large number of transactions at the same time, and the throughput will definitely increase. However, there are many shortcomings and it is currently in the research stage.

25. What is mining

The mining process is to perform a series of conversions, connections and hash operations on the above six fields, and continue to try them one by one. The random number you are looking for, and finally successfully find a random number that meets the conditions: the value after hashing is smaller than the hash value of the preset difficulty value, then the mining is successful, and the node can broadcast the area to neighboring nodes. block, neighboring nodes receive the block and perform the same operation on the above six fields to verify compliance, and then forward it to other nodes. Other nodes also use the same algorithm to verify. If there are 51% of nodes in the entire network If all verifications are successful, even if this block is truly "mined" successfully, each node will add this block to the end of the previous block and add the block toDelete the list that is the same as your own record, and then restart the above process. Another thing to mention is that regardless of whether the mining is successful or not, each node will pre-record the reward of 50 Bitcoins and the handling fees of all transactions (total input-total output) in the first item of the transaction list (this is " The most fundamental purpose of "mining" is also the fundamental reason to ensure the long-term stable operation of the blockchain), the output address is the address of this node, but if the mining is unsuccessful, the transaction will be invalidated without any reward. Moreover, this transaction called "production transaction" does not participate in the "mining" calculation.

26. Mining machines/mines

Mining machines are computers with various configurations, and computing power is the biggest difference between them. A place where mining machines are concentrated in one place is a mining farm

27. Mining pool

Miners join together to form a team, and the computer group under this team is a mining pool. Mining rewards are distributed based on your own computing power contribution.

28. Mining difficulty and computing power

Mining difficulty is to ensure that the interval between generating blocks is stable within a certain short time, such as Bitcoin is issued in 10 minutes

p>

Block 1. The computing power is the configuration of the mining machine.

29. Verification

When verification in the blockchain is a confirmation of the legality of the transaction, each node will verify the transaction once when the transaction message is propagated between nodes. Whether the transaction is legal. For example, verify whether the syntax of the transaction is correct, whether the transaction amount is greater than 0, whether the entered transaction amount is reasonable, etc. After passing the verification, it will be packaged and handed over to the miners for mining.

30. Transaction broadcast

The node sends information to other nodes through the network.

31. Mining fees

For the blockchain to work non-stop like a perpetual motion machine, miners need to maintain the system. Therefore, the miners must be given favorable fees to make it sustainable.

32. Transaction confirmation

When a transaction occurs, the block recording the transaction will be confirmed for the first time, and will be confirmed in every area on the chain after the block. Block is reconfirmed: When the number of confirmations reaches 6 or more, the transaction is generally considered safe and difficult to tamper with.

33. Double transaction

That is, I have 10 yuan, I use the 10 yuan to buy a pack of cigarettes, and then instantly use the 10 yuan that has not yet been paid. Bought another cup of coffee. So when verifying the transaction, you need to confirm whether the 10 yuan has been spent.

34. UTXO unspent transaction output

It is a data structure containing transaction data and execution code, which can be understood as digital currency that exists but has not yet been consumed.

35. Transactions per second TPS

That is, TPSThroughput, tps refers to the number of transactions that the system can process per second.

36. Wallet

Similar to Alipay, it is used to store digital currencies, and blockchain technology is more secure.

37. Cold wallet/hot wallet

A cold wallet is an offline wallet. The principle is to store it locally and use QR code communication to prevent the private key from touching the Internet. A hot wallet is an online wallet. The principle is to encrypt the private key and store it on the server. When it is needed, it is downloaded from the server and decrypted on the browser side.

38. Software Wallet/Hardware Wallet

A software wallet is a computer program. Generally speaking, a software wallet is a program that interacts with the blockchain and allows users to receive, store, and send digital currencies and can store multiple keys. Hardware wallets are smart devices that specialize in handling digital currencies.

39. Airdrop

The project sends digital currency to each user’s wallet address.

40. Mapping

Mapping is related to the issuance of blockchain currency and is a mapping between chains. For example, there are some blockchain companies that have not completed the development of the chain in the early stage. They rely on Ethereum to issue their own currency. The issuance and transactions of the early currency are all operated on Ethereum. With the development of the company, the company's own chain development has been completed. The company wants to map all the previous information on Ethereum to its own chain. This process is mapping.

41. Position

Refers to the ratio of the investor’s actual investment to the actual investment funds

42. Full position

Buy with all funds Enter Bitcoin

43. Reduce the position

Sell some of the Bitcoins, but not all of them

44. Heavy positions

Compared with Bitcoin, Bitcoin accounts for a larger share of funds

45. Short position

47. Stop loss

After obtaining a certain profit, sell the Bitcoin held to keep the profit

48. Stop loss

After losses reach a certain level, sell the Bitcoins you hold to prevent further losses

49. Bull market

Prices continue to rise and the outlook is optimistic

50. Bear market

Prices continue to fall, and the outlook is bleak

51. Long (long)

The buyer believes that the currency price will rise in the future and buys the currency, after the currency price rises, sell at a high price to take profits

52. Short position (short selling)

The seller believes that the currency price will fall in the future, and sells the currency (or Borrow currency from the trading platform) sell it, and after the currency price drops, buy it at a low price to take profits

53. Open a position

Buy virtual currencies such as Bitcoin

54. Cover the position

Buy Bitcoin and other virtual currencies in batches, such as: buy 1 BTC first, then buy 1 BTC

55. Full position

Buy all the funds into a certain virtual currency at once

56. Rebound

When the currency price falls, the price rebounds and adjusts because it falls too fast

57. Consolidation (sideways)

Small price fluctuations, currency prices are stable

58. Cloudy decline

Currency prices decline slowly

p>

59. Diving (waterfall)

The currency price fell rapidly and to a large extent

60. Cutting meat

After buying Bitcoin, the price of the currency dropped sharply. The price fell, and Bitcoin was sold at a loss to avoid further losses. Or after borrowing the currency to go short, the currency price rises, and then buying Bitcoin at a loss

61. Holding up

Expecting the currency price to rise, but unexpectedly the currency price falls after buying; or expecting the currency price to rise. fell, but unexpectedly, after selling, the currency price rose

62. Unwinding

After buying Bitcoin, the currency price fell, causing a temporary book loss, but then the currency price rebounded and the loss was reversed To make a profit

63. Go short

After selling Bitcoin because of the bearish market outlook, the price of the currency continued to rise, and I was unable to buy it in time, so I failed to make a profit

64. Overbought

The currency price continues to rise to a certain height, the buyer's power is basically exhausted, and the currency price is about to fall

65. Oversold

The currency price continues to fall to a certain low, the seller's power is basically exhausted, and the currency price is about to rise

66. Lure bulls

The currency price has been consolidating for a long time, and it is more likely to fall. Most of the short sellers have sold Bitcoin, and suddenly the short sellers pulled up the price of the currency, inducing the long parties to think that the price of the currency will rise and buy one after another. As a result, the short sellers suppressed the price of the currency and locked up the long parties.

67. Lure shorts

After buying Bitcoin, bulls deliberately suppress the price of the currency, making short sellers think that the price of the currency will fall and sell them one after another. As a result, they fall into the trap of bulls

68. What is NFT

The full name of NFT is “Non-Fungible TOkens" is a non-fungible token. Simply put, it is an indivisible copyright certificate on the blockchain. It is mainly used to confirm and transfer digital assets. The difference from digital currency is that it is unique, indivisible, and essentially , is a unique digital asset.

69. What is the Metaverse

The Metaverse is a collection of virtual time and space, consisting of a series of augmented reality (AR), virtual Composed of reality (VR) and the Internet (Internet), digital currency carries the function of value transfer in this world.

70. What is DeFi

DeFi, the full name is Decentralized Finance , that is, "decentralized finance" or "distributed finance." "Decentralized finance", as opposed to traditional centralized finance, refers to various financial field applications established in open decentralized networks, with the goal of establishing A multi-level financial system based on blockchain technology and cryptocurrency to re-create and improve the existing financial system

71. Who is Satoshi Nakamoto?

Medium Satoshi is the developer and founder of Bitcoin. On November 1, 2008, Satoshi Nakamoto published the Bitcoin white paper and mined Bitcoin for the first time on January 3, 2009. Who can use the Bitcoin in the genesis block? Who is Satoshi Nakamoto in Bitcoin, so who is Satoshi Nakamoto? There have been many "Satoshi Nakamotos" in history: In 2013, someone revealed that Mochizuki Shinichi, who has made outstanding contributions in the field of mathematics, is Satoshi Nakamoto. , but no direct evidence was provided. In 2014, hackers hacked into the mailbox used by Satoshi Nakamoto and found the owner of the mail, Dorian Nakamoto. Later, Dorian said that he only obtained the mailbox by chance. The address and password are not Satoshi Nakamoto. In 2016, Craig Wright said that he was Satoshi Nakamoto and could provide Satoshi Nakamoto’s private key. But then, Wright was unable to face everyone’s Questioned and withdrew his statement.

72. Bitcoin and Q Coin are different

Bitcoin is a decentralized digital asset with no issuing entity. Q Coin is issued by The electronic currency issued by Tencent is similar to electronic points, but it is not a currency. Q Coin requires a centralized issuing agency. Q Coin can only be recognized and used because of Tencent’s credit endorsement. The scope of use is also limited to Tencent’s games and In the service, the value of Q coins is completely based on people's trust in Tencent.

Bitcoin is not issued through a centralized organization, but it is widely recognized around the world because Bitcoin can self-certify its trust. , the issuance and circulation of Bitcoin are jointly accounted for by miners across the entire network, and no central organization is needed to ensure that no one can tamper with the ledger.

73. What is a mining machine?

Taking Bitcoin as an example, a Bitcoin mining machine is a professional device that competes for accounting rights by running a large amount of calculations to obtain new Bitcoin rewards. It is generally composed of a mining chip, a heat sink and a fan, and only executes a single calculation program. , consumes a lot of power. Mining is actually a competition between miners for computing power. Miners with more computing power have a greater probability of mining Bitcoin. As the computing power of the entire network increases, it becomes increasingly difficult to mine bits with traditional equipment (CPU, GPU), and people have developed chips specifically for mining. The chip is the core part of the mining machine. The operation of the chip will generate a large amount of heat. In order to dissipate heat, Bitcoin mining machines are generally equipped with heat sinks and fans. Users download Bitcoin mining software on their computers, use the software to assign tasks to each mining machine, and then start mining. Each currency has a different algorithm and requires different mining machines.

74. What is quantitative trading?

Quantitative trading, sometimes also called automated trading, refers to the use of advanced mathematical models to replace human subjective judgments, which greatly reduces the impact of investor sentiment fluctuations and avoids extreme fanaticism or pessimism in the market. make irrational investment decisions. There are many types of quantitative trading, including cross-platform trading, trend trading, hedging, etc. Cross-platform trading means that when the price difference between different target platforms reaches a certain amount, sell on the platform with a higher price and buy on the platform with a lower price.

75. Blockchain asset over-the-counter trading

Over-the-counter trading is also called OTC trading. Users need to find their own counterparties and do not need to match the transaction. The transaction price is determined by negotiation between the two parties. The two parties can fully communicate through face-to-face negotiation or telephone communication.

76. What is a timestamp?

The blockchain ensures that each block is connected sequentially through timestamps. Timestamps enable every piece of data on the blockchain to have a time stamp. Simply put, timestamps prove when something happened on the blockchain and cannot be tampered with by anyone.

77. What is a blockchain fork?

Upgrading software in a centralized system is very simple, just click "Upgrade" in the app store. However, in decentralized systems such as blockchain, "upgrading" is not that simple, and a disagreement may even cause a blockchain fork. Simply put, a fork refers to a disagreement when the blockchain is "upgraded", resulting in a fork in the blockchain. Because there is no centralized organization, every code upgrade of digital assets such as Bitcoin needs to be unanimously recognized by the Bitcoin community. If the Bitcoin community cannot reach an agreement, the blockchain is likely to form a fork.

78. Soft fork and hard fork

Hard fork means that when the Bitcoin code changes, the old nodes refuse to accept the blocks created by the new nodes. Blocks that do not comply with the original rules will be ignored, and miners will follow the original rules and create new blocks after the last block they verified. Soft fork isThis means that old nodes will not be aware of the changes to the Bitcoin code and will continue to accept blocks created by new nodes. Miners may work on blocks they have no understanding of, or validation of. Both soft forks and hard forks are "backwards compatible" to ensure that new nodes can verify the blockchain from scratch. Backward compatibility means that new software accepts data or code generated by old software. For example, Windows 10 can run Windows XP applications. Soft forks can also be "forward compatible".

79. Classification and application of blockchain projects

Judging from the current mainstream blockchain projects, blockchain projects mainly fall into four categories: Category 1: Currency; The second category: platform category; the third category: application category; the fourth category: asset tokenization.

80. USDT against the US dollar

USDT is Tether USD, a token launched by Tether that is against the US dollar (USD). 1USDT=1 US dollar, users can use USDT and USD for 1:1 exchange at any time. Tether implements a 1:1 reserve guarantee system, that is, each USDT token will have a reserve guarantee of 1 US dollar, which supports the stability of the USDT price. The unit price of a certain digital asset is USDT, which is equivalent to its unit price in US dollars (USD).

81. Altcoins and alternative coins

Altcoins refer to blockchain assets that use the Bitcoin code as a template and make some modifications to its underlying technology blockchain, among which Those with technological innovations or improvements are also called alternative coins. Because the Bitcoin code is open source, the cost of plagiarism in Bitcoin is very low. You can even generate a brand new blockchain by simply copying the Bitcoin code and modifying some parameters.

95. Smart Contract

Smart Contract, Smart Contract, is A computer protocol designed to disseminate, verify or execute contracts in an information-based manner. Simply put, an electronic contract is set in advance and once confirmed by both parties, the contract is automatically executed.

96. What is a token?

The token economy is an economic system with Token as the only reference standard, which is equivalent to a pass. If you own Token, you have rights and interests, and you have the right to speak.

97. The difference between big data and blockchain

Big data is the means of production, AI is the new productivity, and the blockchain is the new production relationship. Big data refers to a collection of data that cannot be captured, managed and processed within a certain time range using conventional software tools. It is a massive, high-growth and high-volume data set that requires new processing models to have stronger decision-making power, insight discovery and process optimization capabilities. Diverse information assets. Simply understood, big data is massive data accumulated over a long period of time and cannot be obtained in the short term. Blockchain can be used as a way to obtain big data, but it cannot replace big data. Big data is only used as a medium running in the blockchain and has no absolute technical performance, so the two cannot be confused. (A simple understanding of production relations is labor exchange and consumption relations. The core lies in productivity, and the core of productivity lies in production tools)

98. What is ICO?

ICO, Initial Coin Offering, is the initial public offering of tokens, which is crowdfunding in the blockchain digital currency industry. It is the most popular topic and investment trend in 2017, and the country launched a regulatory plan on September 4. Speaking of ICO, people will think of IPO, and the two are fundamentally different.

99. NumberFive characteristics of digital currency

The first characteristic: decentralization

The second characteristic: having open source code

The third characteristic: having independent Electronic wallet

The fourth characteristic: Constant issuance

The fifth characteristic: Can be circulated globally

100. What is decentralization?

It has no issuer, does not belong to any institution or country, and is a publicly issued currency designed, developed and stored on the Internet by Internet network experts.

100. What is measurement (scarcity)?

Once the total amount of issuance is set, it is permanently fixed, cannot be changed, cannot be over-issued at will, and is subject to global Internet supervision. Because the difficulty of mining and mining changes over time, the longer the time, the greater the difficulty of mining, and the fewer coins are mined, so it is scarce.

101. What is open source code?

The alphanumeric code is stored on the Internet. Anyone can find out the source code of its design, everyone can participate, can mine it, and it is open to the world.

102. What is anonymous transaction? Private wallet private?

Everyone can register and download the wallet online without real-name authentication. It is completely composed of encrypted digital codes. It can be sent and traded globally in real-time point-to-point without resorting to banks or any institutions. It cannot be traced by anyone without my authorization. ,Inquire.

103. What is a contract transaction?

A contract transaction refers to an agreement between a buyer and seller to receive a certain amount of an asset at a specified price at a certain time in the future. The objects of contract trading are standardized contracts formulated by the exchange. The exchange stipulates standardized information such as commodity type, transaction time, quantity, etc. A contract represents the rights and obligations of the buyer and seller.

IV How to make money with blockchain

Blockchain technology will eventually move towards a "decentralized" "demand docking chain network", something that can be connected with demand. You will definitely make money.

Not to mention the participation of some e-commerce giants, even small and medium-sized enterprises, individual investors, and entrepreneurs are deeply involved in blockchain technology, because everyone knows that in In such an undivided field, everyone can use blockchain technology companies to realize the development potential of entering the road to wealth! Those who hesitate are giving others the opportunity to "get there first".

IV In the future, maybe everyone can issue their own digital currency, the key is to do this well

[This article is written by Zanme (zaneds.com) Exclusively titled]

Have you ever thought that maybe one day you would issue your own currency?

The near future is not a dream, the key is how people use and accept it!

The Promise of Central Bank Digital Currency

A central bank digital currency, or CBDC for short, refers to an extension of existing fiat currencies issued by central banks.

CBDC is not a well-defined term. It is used to refer to many concepts. However, most people think this is aNew forms of central bank money. In other words, a liability of the central bank, denominated in an existing unit of account, is both a medium of exchange and a store of value.

Banknotes and coins can be used by anyone and only licensed banks can use them. However, this is not based on blockchain, which is currently used for inter-bank payments.

The Bank for International Settlements (bis) pointed out in a report titled "Central Bank Digital Currencies" released in March that central banks must carefully weigh the impact of issuing digital currencies on financial stability. and the impact of monetary policy.

CBDC may be a new type of digital central bank currency that can be distinguished from the reserves or settlement balances held by commercial banks at the central bank. There are a variety of design choices, including: access (wide vs. restricted); anonymity (from full to complete); availability (from current office hours to 24 hours a day and seven days a week); and interests Characteristics (yes or no).

It raises questions about the monetary role of central banks, the extent of direct exposure to central bank debt, and the structure of financial intermediation.

Part of the current debate is whether CBDC should be widely used or strictly restricted. A CBDC open to everyone would actually allow anyone to have an account with the central bank, similar to the idea that with Bitcoin you are the bank in addition to your Swiss bank account.

The “peer-to-peer” work of CBDCs will greatly weaken the role of traditional banks, or help banks maintain their current dominant position through the banking system.

Commercial banks’ reliance on customer deposits may become less stable, as deposits are more likely to flow to the central bank in times of stress. A national government digital currency would allow central banks to conduct “digital runs.”

A CBDC-for-all model would challenge the current model in which banks take customer deposits and use the money to fund loans that help drive economic growth. The implications for banking business models and financial stability require careful analysis.

Everyone can create money, the problem is how to make it accepted

(American economist Minsky. h.)

Money is the ultimate network effect, and both cryptocurrencies and central bank digital currencies can multiply these effects and undermine the current global financial system’s acceptance of fiat currencies.

One good thing about cryptocurrency is that no one owns it. It is a democratic arrangement in the sense that we all have ownership of the blocks through a distributed ledger. Then you can buy part of it - part or part of the chain. In other words, you can't QE(Quantitative Easing) It, it has an inherent built-in system of rules.

The blockchain economy will provide ample choices and will be a disciplined market and asset economy.

Given the increasing use of electronic payments due to the emergence of new technologies and rising debt levels, serious thinking about the future of money is timely.

Every jurisdiction considering establishing a CBDC should carefully and thoroughly consider its implications before making any decision.

However, it is still unclear whether CBDCs are necessary or desirable for consumers and businesses. The answer will obviously vary from country to country.

Bitcoin shines a spotlight on an old problem in the current system: the rising risks of cross-border retail payments and central bank policy mistakes. CBDC is one way for governments to respond to the challenges of Bitcoin.

VI When will blockchain technology explode? Can virtual currencies bring cross-class opportunities to ordinary people?

Virtual currencies are decentralized and not linked to anything. They are completely dependent on A product supported by the consensus of the community. Take Bitcoin, for example. Because the community consensus finds it valuable, Bitcoin continues to rise until today. However, there are real and fake projects behind virtual currencies, and their values ​​vary. For ordinary people, choice often outweighs effort. Every year, there are people who achieve financial freedom because of virtual currencies, but losses are the ultimate destination for most people. It is very dangerous for ordinary people to participate in virtual currency transactions in an unregulated market that relies entirely on consensus. Don’t blindly think that you are the lucky one who will achieve cross-class status, because capital is always cruel.

Not all virtual currencies can be guided by decentralized blockchain technology. Most virtual currencies just pretend to be virtual currencies on the technical side of the blockchain. In fact, it confuses the concept and there is no new round of leek harvesting model that breaks away from centralization.

This involves several common sense things, what is a blockchain, what is a virtual currency, and what is decentralization.

1. So what is blockchain?

Blockchain originated from Bitcoin. Blockchain is a distributed shared ledger and database. It has the characteristics of decentralization, non-tampering, full traces, traceability, collective maintenance, openness and transparency. .

2. What is virtual currency?

Virtual currency refers to non-real currency. A string of network codes without any physical endorsement, mortgage, or acceptance. It is divided into two types, one is a centralized virtual currency, such as Q Coin; the other is a decentralized digital currency, such as Bitcoin.

3. What is centralization and what is decentralization?

The simplest description isIt is QQ coin, which can be issued unlimitedly by Tencent. You can produce as much as you want. The final right of interpretation lies with Tencent. This is called centralization. There is a fixed number of Bitcoins, and the fixed number of Bitcoins is the upper limit. 21 million Bitcoins, and whoever has the 21 million Bitcoins spread around the world has a say. This is called decentralization.

Only by understanding these three questions can we know the relationship between blockchain technology and virtual currency. Currently, only Bitcoin has this digital cryptocurrency on the market, and it has a fixed amount. But the biggest advantage of this thing is not its circulation, but the addition of cash currencies recognized by various countries as a means of money laundering.

So what you see as the price of Bitcoin in the national market is only the conversion rate of currency conversion given to Bitcoin in a certain transaction, not the real value. Because virtual currency itself has no physical object as acceptance.

Not to mention the so-called digital currencies randomly issued on the market, which are actually the same as Q coins. Tencent said that 1 yuan can be exchanged for a Q coin, and the price of this Q coin is 1 yuan. Two days later, it said that 10 yuan can be exchanged for a Q coin, and this Q coin is 10 yuan. But are Q coins really worth the money? You can only buy a QQ show, which is clothing in the virtual world, also called skin.

According to notices and announcements issued by the People's Bank of China and other departments, virtual currency is not issued by a monetary authority, does not have legal and compulsory monetary attributes, is not a currency in the true sense, and does not have the same characteristics as currency. Equivalent legal status, it cannot and should not be used as currency for circulation in the market, and citizens’ investment and trading in virtual currencies are not protected by law.

Various virtual currencies in the international market pretend to be international currencies under blockchain technology. In fact, they are all flowers in the moon and water in the mirror.

When blinded, coupled with greedy human nature, ordinary people can cross the border and become complete paupers, and they may have to owe a lot of debt.

As the core underlying technology, blockchain’s decentralization, openness, autonomy, non-tamperable information, anonymity and other characteristics help to establish The full-scenario smart management system provides safe, efficient and convenient services for users, smart systems, smart systems, and smart systems to support the construction of smart cities.

The so-called decentralization of virtual currency is a complete lie. It is a fantasy utopia that is absolutely impossible to realize. Virtual currency is a complete money scam. To put it bluntly, the basis for the generation and transactions of various virtual currencies is the Internet and electricity, and the construction of communication networks and power generation facilities relies on the country as the center. Just imagine, losing the country as the center, in a country without laws, without In an environment where the Internet is short of electricity, poor, or even war-torn, how about using a hammer to mine? Virtual currency and all lackeys enjoy the country’s stability zoneAt the same time, they are trying to break away from the center of the country and achieve their own greedy goals of getting something for nothing. Careful analysis shows that the virtual currency ecosystem, from issuance to mining to participation in transactions, combines various typical characteristics of pyramid schemes, gambling and cults. The advocates of virtual currency are a group of outright criminals and should be tried by the law!

No. From the perspective of human history, external situations such as groups of people, tribes, countries, religions, the Internet, etc. all use the propaganda and banner of people's freedom and love, but what is the result? !

Technology has been used in many industries, especially in the financial industry. In the future, with the recognition of various countries, it will definitely change the distribution of classes

Blockchain technology, in fact, that is.

Two essential shortcomings have sealed its fate.

One is that the efficiency is too low.

One is that energy consumption is too high.

So it is impossible to break out.

Crossing classes? It’s already passed, there’s no chance anymore.

Ⅶ How to make your own blockchain currency

Blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order. , and a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.
Virtual currency is simply a digital currency that uses cryptographic algorithms, and virtual currency is also invisible.
The central bank media also stated that private digital currency transactions will not be opened after the situation stabilizes
