㈠ A brief discussion on blockchain: How to use blockchain for transfer transactions
In life, we all have our own bank accounts, and transfers are between bank accounts. of. Similarly, digital currency transfer is the process of transferring Bitcoins from one Bitcoin address to another Bitcoin address. Then if you want to transfer money to others, you need to enter your Bitcoin address, recipient address, transfer amount and handling fee amount on the Bitcoin trading platform, Bitcoin wallet or Bitcoin client. After the payment is confirmed, the transaction information will be broadcast throughout the Bitcoin network. Every 10 minutes, miners will package the unaccounted transactions in the Bitcoin network into a block. This completes a confirmation. At this time, Bitcoin It has been transferred to the recipient's account. Generally, it needs to be confirmed 6 times to ensure that the transaction record cannot be tampered with by anyone before the transfer can be truly completed.
We talked about the transfer fee above, but how much is the fee for one transfer?
The Bitcoin transfer fee is a fee paid by traders to miners. It is used to encourage miners to compete for accounting and provide sufficient computing power for Bitcoin to ensure the security of the Bitcoin network. Some Sometimes we also call this fee the mining fee. When a user initiates a transfer on the Bitcoin network, a handling fee is unavoidable. Generally, it is 0.001-0.0015 Bitcoins. Due to the limited capacity of transaction records that can be accommodated in blocks, miners will give priority to packaging transaction records with high handling fees. , so a little more handling fee can be credited faster.
This article is compiled and published by Huixinyun. I will continue to update the "Brief Talk about Blockchain" series. This series will introduce some basic knowledge of blockchain and digital currency, so stay tuned!

㈡What problems does the blockchain solve?
Use blockchain technology as currency because the blockchain will inevitably generate tokens, and all transaction participants agree that it has value. Blockchain Chain technology helps it function as currency. We find that blockchain currencies are likely to first gain adoption for private transactions, international transactions, and microtransactions, and then eventually expand to become the default currency for all transactions. Blockchain technology is also useful for individuals executing microtransactions. If one person wanted to send $1.00 to another person, the fees in a world without blockchain could easily reach 30-40% of the total transaction (.30—.30—.40). As a result, companies are forced to shift transactions to monthly invoices, and these high fees also discourage founders from starting a business on small amounts of money in the first place. Assuming an entrepreneur wants to start a business, an individual in France can send $1 directly to farmers in Kenya to help them build agricultural infrastructure. awareness of these payments among the entrepreneur and his potential donorsAfter almost half of the funds flow to intermediary entities, entrepreneurs may give up and donors may leave. On the other hand, if an entrepreneur in a developing country wants to transfer his wealth (e.g., $2-5 per day) from an unstable local currency to a more stable international currency, he will face high international double fees The troubles are transaction fees for small transaction sizes and high intermediary fees. Blockchain-based currencies offer solutions to these problems. Using Blockchain Technology as a Store of Value Blockchain technology also has the potential to provide new independent stores of value. Today, the classic store of independent value is gold, as humanity decided to be independent from nation-states (e.g. Canada) or unions of nations (e.g. the European Union) rather than other mainstream currencies (e.g. the United States, where the dollar is closely associated with the success of the United States of America). Gold typically has an inverse relationship with the U.S. dollar: in other words, gold serves as a hedge against the current global financial system. Since gold is difficult to store (heavy, relatively unsafe), digital blockchain currencies represent an attractive alternative. If digital currencies become more stable over time (currently, they are extremely unstable), they may one day add to or subtract from assets like gold (for hedging purposes). If digital currencies replace traditional currencies such as the US dollar and the euro, then these digital currencies will represent and dominate the financial system. In this world, these currencies will no longer be a useful hedge against the current status quo: they will become the status quo! And we hope that investors can focus on gold, similar assets and non-mainstream digital currencies to hedge against these now mainstream digital currencies. Using Blockchain Technology to Facilitate Simple Information Exchange Ultimately, the value of blockchain technology comes from its potential to secure and automate the transfer of information, an endeavor with endless opportunities. While blockchain-based currencies represent a great opportunity to streamline the transfer of information, any current process or system that transmits information digitally (i.e., anything on the internet) could be revolutionized by blockchain technology. In the blockchain world, programmable rules that determine how a blockchain delivers information are called smart contracts. Smart contracts are really just automated contracts. To implement a smart contract, three things need to be done. First, all stakeholders need to agree that digital tokens have value. Second, all stakeholders need to agree on every definition in the smart contract. Third, digital tokens need to be integrated with every defined programmatic fact. Using blockchain technology to facilitate complex information exchanges An example of a complex information market using blockchain technology is the storage of digital information. Today, a large portion of the Internet is hosted by similar offerings from Amazon Web Services (AWS) and other intermediary entities. These entities build and maintain global data storage and servers to support cloud infrastructure. However, in the blockchain world, companies can use information storage blockchain tokens (we call them fictional tokens 'FileStorageCoin') in exchange for secure storage on a highly distributed network, at a price charged by physical intermediaries such as AWS Just a little part. Although blockchain can help users from storage, connection, bandwidth,Gain more value from website visits and content creation, but the technology is not limited to digital information; the technology can also make physical world assets more liquid (easier to sell and buy), making them more reducible. In other words, blockchain can better facilitate ownership of assets by multiple people.
㈢ Where can I find a more detailed explanation of blockchain applications
Blockchain applications include mathematical currency, payment and settlement, digital bills, proof of rights and interests, and bank credit reporting
Each The specific application is explained as follows:
1. Digital currency
At present, the most extensive and successful application of blockchain technology is the digital currency represented by Bitcoin. Digital currency has developed rapidly in recent years. Due to the characteristics of decentralized credit and frequent transactions, it has a high transaction value and can maintain a relatively stable price through the development of hedging financial derivatives as a quasi-super-sovereign currency. Digital currency has established digital currency transaction credit backed by sovereign currency. The greater the transaction volume and the more frequent transactions, the stronger the digital currency transaction credit foundation. Once the blockchain credit system is implemented globally, digital currency will become a gold-like global payment credit.
2. Payment and settlement
At this stage, settlement and payment of commercial trade transactions all rely on banks. This traditional method of conducting transactions through intermediaries requires the account opening bank, counterparty bank, central bank, and overseas bank. In this process, each institution has its own accounting system, needs to establish an agency relationship with each other, and needs a credit line; each transaction needs to be recorded in its own bank, and must also be cleared and reconciled with the counterparty, resulting in Transactions are slow and costly. Compared with the traditional payment system, blockchain payment is carried out directly by both parties to the transaction without involving intermediaries. Even if part of the network is paralyzed, it will not affect the operation of the entire system. If a universal distributed inter-bank financial transaction protocol is built based on blockchain technology to provide users with cross-border, real-time payment and clearing services in any currency, cross-border payments will become convenient and low-cost.
Take cross-border exchange as an example. If I open an account in a small bank in my country and transfer money to another small bank abroad, the transfer process under the traditional SWIFT system requires the following steps: First, I send money to the small bank to which I belong. Banks submit applications; second, small banks submit applications to large banks in the same country that have signed exchange terms; third, large banks wire transfers to overseas cooperative banks; fourth, cooperative banks remit funds to small overseas banks. Currently, the process takes anywhere from 10 minutes to two days, depending on the country. If you use blockchain-based settlement technology and place an order at a market maker while remitting RMB, a trading bank participating in the system in the world will receive the order, and the two parties will shake hands to complete the exchange. The average payment confirmation speed will be in a few seconds. Within seconds.
3. Digital bills
Digital bills are a brand-new bill presentation form developed by combining blockchain technology with bill attributes, regulations, and markets. It is completely consistent with the technical architecture of the existing electronic bill system. different. The core advantages of digital bills are mainly reflected in: First, realize the disintermediation of bill value transfer. In traditional bill transactions, bill intermediaries often use information differences to match. After point-to-point transactions are realized with the help of blockchain, bill intermediaries will lose their intermediary functions and reposition their identities. The second is to effectively prevent bill market risks. Due to the blockchain's non-tamperable timestamps and the fact that it is open to the entire network, once a transaction is made, there will be no default, thus avoiding the problems of "one vote selling more" for paper tickets and out-of-sync payment and endorsement of electronic tickets. Third, the system construction and data storage do not require a central server, eliminating the development costs of central applications and access systems, reducing the maintenance and optimization costs of the system under the traditional model, and reducing the risks caused by system centralization. The fourth is to standardize market order and reduce regulatory costs. The non-tamperable timestamp formed by the continuous connection of blockchain data greatly reduces the cost of regulatory review. The completely transparent data management system provides a trustworthy traceability path, and shared constraints can be established in the chain for regulatory rules through programming. code to achieve full coverage and hard control of regulatory policies.
4. Proof of Rights and Interests
Every node participating in the maintenance of the blockchain can obtain a complete data record. Using the characteristics of the blockchain's reliability and collective maintenance, the rights of the owners of rights and interests can be confirmed. For the need to store permanent records, blockchain is an ideal solution for scenarios such as land ownership and equity transactions. Among them, proof of equity is the field with the most applications currently. Equity owners can prove their ownership of the equity with their private keys. When the equity is transferred, it is transferred to the next owner through the blockchain system. The property rights are clear and the records are clear. The entire process does not require the involvement of a third party.
During a keynote address at the 2015 European Financial Journalism Awards for Excellence in Trading Technology in London, Nasdaq CEO Bob Greifeld announced that the exchange intends to use blockchain technology to manage its proxy voting system. Proxy voting is an important and time-consuming operation used by a listed exchange. The application of blockchain technology can allow shareholders to vote without having to attend the company's annual meeting. People can vote using their mobile phones, and Always keep voting records. Blockchain technology is regarded as an advanced technology in the field of equity trading that can ensure transparent transactions in a shorter time.
5. Bank Credit Reference
At present, when developing commercial bank credit business, whether it is for enterprises or individuals, the most basic consideration is the financial credit of the borrower itself. Each bank uploads the repayment status of each borrower to the central bank's credit reference center. When inquiries are needed, the bank will download the reference from the central bank's credit reference center with the customer's authorization. There are problems such as incomplete information, inaccurate data, low usage efficiency, and high usage costs. In this field, the advantage of blockchain is that it relies on program algorithms to automatically record massive information and store it on every computer in the blockchain network. The information is transparent, difficult to tamper with, and has low cost of use. Commercial banks store and share customers' credit status in their own institutions in an encrypted form. Customers do not need to go to the central bank to apply for a check when applying for a loan.Credit inquiry is decentralized, and lending institutions can complete all credit inquiry work by retrieving the corresponding information data from the blockchain.
In short, blockchain has become one of the hot spots of innovation in the financial industry. However, as a new technology, blockchain also has considerable risks. The current settlement system based on blockchain technology is very sensitive to regulatory risks. If participants are worried about the uncertainty of regulatory policies, it may cause the payment system to collapse due to instability. In addition, since its operating rights are controlled by developers, the obvious technical disadvantage is that if the operator itself controls more than 51% of the computing power of the entire network, it can achieve double payment, leading to a breakdown of trust. This is also an important issue that needs to be solved during the application of blockchain technology.
㈣ Share: What is AB position, double position hedging contract
OKToKen is the world’s first hedging and follow-up community. In the entire digital contract trading market, more than 95% of users are losing money , less than 5% of users can actually make profits, and these 5% also include large households and institutions.

The trader trades on the A-position exchange, and the community uses the API Trading in warehouse B
㈤ Blockchain: What is quantitative trading
Quantitative trading, sometimes also called automated trading, refers to the use of advanced mathematical models to replace human subjective judgment< br />
Broken.
It greatly reduces the impact of investor sentiment fluctuations and avoids making
irrational investment decisions when the market is extremely fanatical or pessimistic.
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.
Trend trading is a bit more complex, issuing sell and buy signals based on indicators of the trend. Hedging is
means doing two things at the same timeA transaction related to the market, with opposite buying and selling direction, equal quantity, and balanced profit and loss, in order to achieve the effect of hedging risks
. Quantitative trading is a sign of a mature trading market.
㈥ 108 essential knowledge points for getting started with blockchain
108 essential knowledge points for getting started with blockchain
(Welcome
1. What is a blockchain?
Package the information of multiple transactions and the information indicating the block together. After verification, the package It's 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 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, the influx of large amounts of traffic may cause the website to fail to work properly and suffer 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 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, stores dataA data structure. The bottom layer is the original data contained in all blocks. The upper layer is the hash value of each block. The hash of this layer is combined in pairs to generate a new hash value to form a new layer. Go up 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 block
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 sends theThe message from the server is sent again. 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 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 unite 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, to verify whether the transaction syntax is correct and whether the transaction amount is greater than 0, enterWhether the 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. As the company develops, the company's own chain development is completedThe 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
All funds are bought 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
Compared with Bitcoin, the share of funds is larger
46. Short position
Sell all the Bitcoins you hold and convert them all into funds.
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, 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 it from the trading platform) (coin) sell, wait for the price of the currency to fall, buy 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, for example: buy 1 BTC first, and then buy 1 BTC later
55. Full position
All funds are purchased at one time to buy a certain virtual currency
56. Rebound
When the currency price falls, the price rebounds and adjusts because it falls too fast
57 .Consolidation (sideways)
The price fluctuation is small and the currency price is stable
58. Yin fall
The currency price declines slowly
59. Diving (waterfall)
The currency price fell rapidly and to a great extent
60. Cutting meat
After buying Bitcoin, the price of the currency fell. To avoid expanding losses, sell Bitcoin 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 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 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", which is a non-fungible token. Simply put, it is an indivisible token on the blockchain. Copyright certificate is mainly used to confirm and transfer the rights of digital assets. The difference from 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 based on open decentralized networks. The goal is to establish a multi-level financial system based on blockchain technology and cryptocurrency. as a basis to re-create and improve existingFinancial 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 blockchainLove, and no one can tamper with it.
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: 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 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 blockchain It is a 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)

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.
101. 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.
102. 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.

㈦ 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", created a reliable "cooperation" mechanism, and has broad application prospects.
