⑴ What is blockchain and how to make money with blockchain
Blockchain is a computer technology based on distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. New application models. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
How to make money in the blockchain:
1. Earn commissions through promotion.
The blockchain approach is to first register an exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you will get a commission.
2. Coin speculation.
Speculating in currencies is like speculating in stocks. Coin speculation is a way to make money on the Blockchain with the lowest threshold.
3. Mining.
"Mining" in Bitcoin is the accounting process. This process requires grabbing, and if you grab the opportunity to bookkeeping rights, you will be rewarded, and the reward is Bitcoin. This behavior is "mining".
4. Develop wallet.
The wallet is the infrastructure of the blockchain, just like the "Alipay Zheng Xinque" or "WeChat Pay" of the blockchain.
Extended information:
1. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the bottom layer of Bitcoin. technology. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block. piece.
2. Blockchain was born from Satoshi Nakamoto’s Bitcoin. Since 2009, various Bitcoin-like digital currencies have appeared, all based on public blockchains.
3. On January 20, 2016, the Digital Currency Seminar of the People’s Bank of China announced that it had achieved phased results in digital currency research. The meeting affirmed the value of digital currency in reducing the issuance of traditional currency and stated that the central bank is exploring the issuance of digital currency. The expression of the People’s Bank of China’s Digital Currency Seminar has greatly enhanced the confidence of the digital currency industry. This is the first time that the five central bank ministries and commissions have expressed a clear attitude towards digital currencies since they issued a notice on preventing Bitcoin risks on December 5, 2013.
Blockchain - Network
⑵ Blockchain Technology
Background: After the birth of Bitcoin, it was discovered that the technology was very advanced and the block was discovered chain technology. Bitcoin and blockchain technology were discovered at the same time.
1.1 The purpose of the birth of Bitcoin:
①Currency transactions have records, that is, ledgers;
②The disadvantages of centralized institution accounting - it can be tampered with; Yi Chaofa
Bitcoin solves the first problem: anti-tampering - hash function
1.2 hash functionNumber (encryption method)
① Function: Convert a string of any length into a fixed-length (sha256) output. The output is also called a hash value.
② Features: It is difficult to find two different x and y such that h(x)=h(y).
③Application: md5 file encryption
1.3 Blockchain
①Definition
Block: Split the general ledger into zones Block storage
Blockchain: On each block, add a block header. It records the hash value of the parent block. By storing the hash value of the parent block in each block, all blocks are connected in order to form a blockchain.
②How does the blockchain prevent transaction records from being tampered with?
After the blockchain is formed, tampering with any transaction will cause the hash value of the transaction block to be different from that of its sub-blocks. , tampering was discovered.
Even if you continue to tamper with the hash value in the sub-block header, the hash value in the sub-block will be different from that in the grandchild block, and the tampering will be discovered.
1.4 The essence of blockchain
①The essence of Bitcoin and blockchain: a big ledger visible to everyone, only recording transactions .
②Core technology: Through cryptographic hash function + data structure, it ensures that the ledger records cannot be tampered with.
③Core function: Create trust. Fiat currency relies on government credibility, and Bitcoin relies on technology.
1.5 How to trade
①To conduct transactions, you need an account number and password, corresponding to the public key and private key
Private key: a string of 256-bit binary numbers , no application is required to obtain it, and you don’t even need a computer. You can generate the private key by tossing a coin 256 times.
The address is converted from the private key. The address cannot reverse the private key.
The address is the identity, which represents the ID in the Bitcoin world.
After an address is generated, it can only be known by everyone if it enters the blockchain ledger.
②Digital signature technology
Signature function sign (Zhang San’s private key, transfer information: Zhang San transfers 10 yuan to Li Si) = signature of this transfer
< p> Verify Korean verify (Zhang San’s address, transfer information: Zhang San transfers 10 yuan to Li Si, signature of this transfer) = TrueZhang San uses his own signature function sign() The private key signs this transaction.
Anyone can verify whether the signature hasIssued by Zhang San himself who holds Zhang San’s private key. It returns true, otherwise it returns false.
sign() and verify() are cryptographically guaranteed not to be cracked. ·
③Complete the transaction
Zhang San will provide the transfer information and signature to the entire network. Under the premise that the account has a balance, after verifying that the signature is true, it will be recorded in the blockchain ledger. Once recorded, Zhang San's account will be reduced by 10 yuan, and Li Si's account will be increased by 10 yuan.
Supports one-to-one, one-to-many, many-to-one, and many-to-many transactions.
In the Bitcoin world, private keys are everything! ! !
1.6 Centralized Accounting
① Advantages of Centralized Accounting:
a. No matter which center keeps accounts, don’t worry too much
< p> b. Centralized accounting, high efficiency②Disadvantages of centralized accounting:
a Denial of service attack
b Stop service after getting tired
p>c Central institutions are vulnerable to attacks. For example, destroying servers and networks, committing self-intrusion, legal termination, government intervention, etc.
All attempts at confidential currencies with centralized institutions in history have failed.
Bitcoin solves the second problem: how to decentralize
1.7 Decentralized accounting
①Decentralization: Everyone can keep accounts. Everyone can keep a complete ledger.
Anyone can download open source programs, participate in the P2P network, monitor transactions sent around the world, become an accounting node, and participate in accounting.
② Decentralized accounting process
After someone initiates a transaction, it is broadcast to the entire network.
Each accounting node continues to monitor and continue transactions across the entire network. When a new transaction is received and the accuracy is verified, it is put into the transaction pool and continues to be propagated to other nodes.
Due to network propagation, the transactions of different accounting nodes at the same time are not necessarily the same.
Every 10 minutes, one person is selected from all accounting nodes in a certain way, and his transaction pool is used as the next block and broadcast to the entire network.
Other nodes delete the transactions that have been recorded in their own transaction pool based on the transactions in the latest block, continue accounting, and wait for the next selection.
③Decentralized accounting features
A block is generated every 10 minutes, but not allAll transactions within these 10 minutes can be recorded.
The accounting node that obtains the accounting rights will be rewarded with 50 Bitcoins. After every 210,000 blocks (approximately 4 years), the reward is halved. The total amount is about 21 million, and it is expected to be mined in 2040.
Recording the reward of a block is also the only way to issue Bitcoin.
④ How to allocate accounting rights: POW (proof of work) method
Compete for accounting rights by calculating mathematical problems on several accounting points.
Find a random number that makes the following inequality true:
There is no other solution except traversing the random numbers starting from 0 and trying your luck. The process of solving the problem is also called mining.
Whoever solves the problem correctly first will get the accounting rights.
If a certain accounting node finds the solution first, it will announce it to the entire network. After other nodes verify that it is correct, a new round of calculation will start again after the new block. This method is called POW.
⑤ Difficulty adjustment
The generation time of each block is not exactly 10 minutes
As Bitcoin develops, the computing power of the entire network does not increase.
In order to cope with changes in computing power, the difficulty will be increased or decreased every 2016 blocks (approximately 2 weeks), so that the average time for each block to be generated is 10 minutes.

⑶ 108 knowledge points for getting started with blockchain
1. What is a blockchain?
The information of multiple transactions and the information indicating the block are packaged 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 number of 21 million. 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 shared and replicated ledger among network members.and synchronized databases. 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 controlled by one person In the hands of the organization.
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 the relationship between usersIn what way it is 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 refers to "smart contracts", which are 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 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 are easy to compareMining machines with low computing power generate blocks quickly, 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 the next
23 replay attack
The hacker resends the message that has been sent to the server. Sometimes this can deceive the server into 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, delete the list in the block that is the same as its own record, and resurrect again. 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 this node.Click the address, but if the mining is unsuccessful, the transaction will be invalidated and there will be no 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’s 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 throughput, tps refers to the number of transactions 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

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, buys the currency, and waits for the currency price After rising, 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 he holds (or borrows currency from the trading platform). After the currency price drops, the seller will sell the currency at a low price. Buy and take profits
53. Open a position
Buy Bitcoin and other virtual currencies
54. Cover the position
Buy in batches Bitcoin and other virtual currencies, for example: buy 1 BTC first, then buy 1 BTC
55. Full position
Buy all the funds into a certain virtual currency at one time< /p>
56. Rebound
When the currency price falls, the price rebounds and adjusts because it falls too fast
57. Consolidation (sideways)
The price fluctuation range is small and the currency price is stable
58. Overcast drop
The currency price declines slowly
59. Diving (waterfall)
The price of the currency fell rapidly and to a great extent
60. Cutting the flesh
After buying Bitcoin, the price of the currency fell. In order to avoid the expansion of losses, the Bitcoin was sold at a loss. Or after borrowing the currency to go short, the currency price rises, and you buy Bitcoin at a loss
61. Hold on
Expect the currency price to rise, but unexpectedly the currency price falls after buying; or expect the currency price to fall. 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 has basically been 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, causing the long parties to get stuck
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", which is non-fungible tokens. Simply put, it is an indivisible copyright certificate on the blockchain. Its main function is The difference between digital asset confirmation and transfer and digital currency is that it is unique and indivisible. In essence, it 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 reality (VR) and the Internet (Internet) Composed of digital currency, which carries the function of value transfer in this world.
70. What is DeFi
DeFi, the full name is Decentralized Finance, which is "decentralized finance" or "distributed finance". "Decentralized finance", as opposed to traditional centralized finance, refers to various financial applications established in open decentralized networks. The goal is to establish a multi-level financial system based on blockchain technology and cryptocurrency. As a basis, re-create and improve the existing financial system
71. Who is Satoshi Nakamoto?
72. Bitcoin is different from Q Coin
Bitcoin is a decentralized digital asset with no issuing entity. Q Coin is an electronic currency issued by Tencent. It is similar to electronic points, but it is not actually a currency. Q Coin requires a centralized issuing institution. Q Coin can only be recognized and used because of the credit endorsement of Tencent. The scope of use is also limited to Tencent's games and services. The value of Q coins is entirely based on people's trust in Tencent.
Bitcoin is not issued through a centralized institution, 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 are not A central authority is also 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 equipment 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 performs 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. A soft fork means that old nodes are not aware of the changes to the Bitcoin code and 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: Coin type; second type: platform type; third type: application type; fourth type: 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.

Big data is the means of production, AI is the new productivity, and 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 as, large numbersData 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)

99. Five characteristics of digital currency
The first characteristic: decentralization
The second characteristic: having open source code
The third feature: independent electronic wallet
The fourth feature: constant issuance
The fifth feature: global circulation
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.
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.

⑷ What is blockchain
When everyone talks about blockchain and digital currency, they all listen to it Discoloration, fear and avoidance
What is blockchain?
What is digital currency?
Let the public be more intuitive and clearly understand that this is blockchain.
What is blockchain? Many people are still not very clear about blockchain. Let’s give you a simple explanation. Let’s take a look.
1. Blockchain concept
Professional terminology: Blockchain is a distributed data storage, point-to-point transmission,
consensus mechanism, encryption algorithm and other new application models of computer technology.
Popular handout: Quoting the explanation in the video, the blockchain replaces all these opaque cups with transparent cups, so that you can always know where your money is, and it will always belong to you. Will be stolen by others.
2. Blockchain
Basic characteristics
1. Decentralization
In traditional centralized network systems In a decentralized blockchain network, hackers can destroy the network by attacking a central node. However, in a decentralized blockchain network, there is no central node to attack
Moreover, the decentralized transaction method is convenient and convenient. There is no third party intervention and direct point-to-point interaction, making large-scale information interaction a reality
It not only ensures that the information is not leaked, but also ensures that the key is in your hand, and transactions can be fast and convenient.
2. Openness
The system is open. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface, so the entire system information is Like a transparent cup, everyone can see what's inside.
3. Information cannot be tampered
When a block is verified and added to the blockchain, it will be stored permanently and cannot be changed unless the system is controlled at the same time. More than 51% of the nodes, otherwise the modification of the database on a single node will be invalid, so the data stability and reliability of the blockchain are extremely high.
4. Anonymity
Since the data exchange between nodes in the blockchain follows a fixed and predictable algorithm, the blockchain network does not require trust and can be based on addresses. Non-personally identifiable data is exchanged. The anonymity of the blockchain is a double-edged sword. It not only protects the confidentiality of information and the security of transactions, but it also causes rampant illegal transactions. It has caused difficulties for law enforcement agencies and created a sense of distrust among users.
The above is a partial introduction to the basics of blockchain. I believe that as the public learns more about blockchain, this technology will be recognized and used by more people.
⑸ How to make profits from blockchain
Blockchain is a revolutionary technology that provides centralization, privacy protection, and Turing-perfect smart contract technology foundation, and is called the next network. Revolution. By purchasing blockchain items to mint high-purpose digital assets, we can rationally allocate our property, invest rationally, and gain income through the added value of tokens. How does blockchain make profits?
Invest in blockchain tokens and make money by purchasing tokens and other digital assets on exchanges. There are two ways to buy tokens. One is currency trading, through BTC, ETH, USDT, etc. Mainstream currency digital currencies are traded. The other is over-the-counter trading, using legal currency to purchase digital currencies and trading between digital currencies.
⑹ How much commission does Alpha Hitch receive?
If there is no platform fee, when the passenger's payment is completed, the driver can choose to receive cash or exchange for blockchain work points equivalent to the order amount. Users can also cash in work points into cash rewards.
70% of the platform’s revenue will be distributed to all ACAR circulators in the form of cash income, similar to dividends.
