Ⅰ 108 knowledge points for getting started with blockchain

1. What is blockchain

Put the information of multiple transactions and indicate the area The information of the block is packaged together, and 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 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, it is more than 51%If a node is 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 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. You can quickly find the bottom layer you want without downloading all the data.historical 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 resends the message that has been sent to the server. Sometimes this can deceive the server into responding multiple times.

24. Directed acyclic graph

Also called data set DAG (directed acyclic graph), DAG is an ideal multi-chain data structure. Most of the blockchains we talk about now are single chains, that is, one block 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, 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 toMaintain this 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

All funds are bought Deposit Bitcoin

43. Reduce the position

Sell some of the Bitcoins, but not all of them

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 large extent

60. Cutting meat

After buying Bitcoin, the currency price fell, as Avoid expanding losses and selling 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 currencyHowever, the price rose

62. Unwinding

After buying Bitcoin, the price fell, causing a temporary book loss, but then the price rebounded and the loss turned into profit

63. Going short

After selling Bitcoin because of the bearish market outlook, the price of the currency continued to rise. 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 At this point, the seller's power has basically been exhausted, and the currency price is about to rebound

66. Lure bulls

The currency price has been consolidating for a long time, and it is more likely to fall. Most short sellers have sold Bitcoin. Suddenly the short side pulls up the currency price, inducing many parties to think that the currency price will rise and buy one after another. As a result, the short side suppresses the currency price and locks in the long side

67. Short-selling

After the bulls bought Bitcoin, they deliberately suppressed the price of the currency, making the short sellers think that the price of the currency would fall and sell them one after another. As a result, they fell into the trap of the 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, and its main function is to confirm the digital assets. The difference between rights and transfers 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 based on 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 coins need to be issued in a centralized mannerInstitutions, Q coins 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 blockA disagreement occurred when the chain was being "upgraded," resulting in a blockchain fork. 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.

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.

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, 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)

ICO, Initial Coin Offering, initial public token issuance, is the first step in the blockchain digital currency industry. Crowdfunding.

For example, on the blockchain mining machine APP platform, users can become miners by registering as members, and miners can earn income through various mining activities, such as purchasing a dedicated mining equipment. You can start mining, and for example: mining when you buy it, mining when you trade, mining when you sign in, mining when you evaluate, mining when you buy a mining machine, mining when you invite people, etc. In other words, any task operation performed by users on the blockchain platform can be regarded as mining behavior.

Every mining behavior of users is contributing value to the platform, and the platform should reward them with coins. The mines mined by users can be circulated in the merchant's own ecosystem. For example, they can be used for financial transactions such as buying and selling on the platform, and can also be used for purchase deductions, cash withdrawals, etc.

Ⅲ What is the principle of Bitcoin and blockchain and what is mining (3)

Continuing from the previous issue "Bitcoin and What is the principle of blockchain? What's going on with mining? (2)》

Before I start, let me share with you an interesting thing I saw yesterday.

(On the gate of a community in Shenyang, 66 locks are hung one after another, and it is known as the "cheapest access control system".

It turns out that there were always foreign vehicles coming in and out of this community, so the owners spontaneously built this "access control system". Each lock has a number, and the car owners in the community only need to take the key to open the corresponding lock to open the door. Residents said that this This method saves money and effort, and is especially easy to use.)

This is equivalent to the technical materialization of blockchain ：

Specific features: Decentralization (no need for unified management); traceability (whoever has the lock can find it); non-tamperability (one person has one lock) One key), this is the most thorough understanding I have ever had of blockchain.

"Let's stop talking and get back to the story." We said before that there is a difficulty setting of N bits. How to determine this N bit? Obviously, the previous 0, The more there are, the more difficult the problem becomes.

Why is it difficult to count more? Let's imagine that in this problem you can't back-calculate, you can only calculate one by oneA random trial, the probability of 0 appearing in each digit and the probability of 1 appearing in each digit are both 50%, so what is the probability of the first 0? The probability is 1/2. If the second digit is 0, what is the probability? The probability is also 1/2, the third digit is 0, the probability is also 1/2, until the last digit is 0, the probability is also 1/2, so when multiplied, the result is the nth power of (1/2).

Obviously, the larger n is, the higher the difficulty is, and the smaller n is, the smaller the difficulty is.

When Satoshi Nakamoto was designing it, he ensured that he would produce a block and package it every ten minutes. With thousands of pieces of information, how can we guarantee it? That is to say, adjust the difficulty of this n?

Let’s take an example. For example, there are 10,000 mining machines in the world. The computer power of each of these 10,000 mining machines is 14 T per second. , that is, 14T hash operations can be calculated per minute. So what is 14T?

First of all, 1T is 10 to the 12th power, so this number is (1.4*10) to the 13th power per second, which is for each mining machine Calculated in one second, multiply by 10 to the 4th power, which means there are 10,000 mining machines, and then you have to multiply it by 10 minutes, which is about 600 seconds. This number is about (8*10) to the 19th power. In other words, we can perform so many operations in ten minutes.

Then let’s think about it again. If the probability is (1/2) raised to the nth power, what do you think? If you come up with this block, the number of calculations you need to make is 2 to the nth power. If your probability is 1/64, you will have to calculate this block 64 times on average.

By the same token, if you have calculated it so many times, then it is roughly equal to the power of 2. We can find through calculation that if n is equal to 66, the probability of your appearance at this time can be calculated. It is the 66th power of (1/2), and then the average number of times you need to calculate is 266, which is about the 19th power of (8*10), so in this case the miner will set the difficulty to n equal to 66, so the first person who can purchase and calculate that the first 66 bits are all 0 will successfully package the block and successfully mine the mine.

You have no way to make your luck better. All you can do is buy more mining machines and mine as hard as you can, so that you may get this Bitcoin.

This is probably the principle.

IV Blockchain, 4 types, how much do you know

——Hello, I am mentality, focusing on sharing my understanding of blockchain and investment thinking. hope this helps.

According to different usage requirements and scenarios, blockchain is divided into four types: public chain, alliance chain, private chain and hybrid chain.

1. Public chain

Public chain means that anyone at any node in the world and at any geographical location can enter the system to read data, send transactions, and compete. Blockchain that participates in consensus such as accounting. No institution or individual can tamper with the data in it, so the public chain is completely decentralized.

Bitcoin and Ethereum are both representatives of public chains. Public chains generally encourage participants to compete for accounting (i.e. mining) by issuing tokens to ensure data security and consensus updates.

Bitcoin generates one block every 10 minutes on average, and its POW mechanism is difficult to shorten the block time. The POS mechanism can shorten the block time relatively speaking, but it is more likely to cause forks. So the transaction needs to wait for more confirmations before it is considered safe.

It is generally believed that a block in Bitcoin is secure enough after 6 confirmations, which takes about an hour. Such a confirmation speed is difficult to meet commercial-level applications. Therefore, public chains such as ETH and EOS that support more writing speeds are constantly developing.

2. Alliance chain

Alliance chain refers to a blockchain that is jointly participated and managed by several institutions, with each institution running N nodes.

The data of the alliance chain only allows different institutions in the system to read, write and trade. The PKI-based identity management system transactions or proposals are initiated through digital certificates and are verified by the joint signature of the participants. A consensus is reached, so there is no need for proof of work (POW), and there is no digital currency (token), which improves the efficiency of transaction completion and saves a lot of computing costs (computing hardware investment and electricity energy consumption).

Normally, nodes participating in the alliance chain will be divided into different read and write permissions, which can support more than 1,000 data writes per second.

3. Private chain

Unlike the public chain, which is completely decentralized, the private chain’s access rights are controlled by an organization, and the participation qualifications of each node are controlled by the organization. Authorization control.

Since the participating nodes are limited and controllable, private chains often have fast processing speeds and can support more than 1,000 data writes per second, while reducing the transaction costs of internal nodes.

Nodes can participate under real names and therefore have financial attributes to confirm identity. The value of the private chain is mainly to provide a safe, traceable, non-tamperable, and automatically executed computing platform, which can prevent both internal and external security attacks or tampering of data, which is difficult to achieve in traditional systems.

The application scenarios of private chains are generally within enterprises, such as inventory management in branches.It can also be used in areas such as government budgeting and execution that can be supervised by the public. Large financial groups are also currently inclined to use private chain technology.

4. Hybrid chain

When the respective advantages of public and private chains are combined, a hybrid chain will appear. The development of hybrid chains is difficult, but the prospects are broad.

In the future market, there will definitely be giant companies that develop underlying technologies and protocols. These giant companies will set up public chains, private chains or alliance chains for different purposes, based on performance and security. and the different needs of application scenarios, and then grafted on applications in different industries. For example, a communication public chain that supports high concurrency, a payment alliance chain that focuses on security, etc.

A like and a follow are the greatest support for me. See you tomorrow.

IV What does blockchain mining mean?

"Mining", as the name suggests, is the action that can appear in our minds, which is digging in the soil with a shovel, but now we It’s no longer a shovel, but a computer. Instead of digging in the soil, we dig in a pool of data, and instead of digging for physical objects like gold and coal, we compete for the right to keep accounts. 1. Mining is the process of confirming transactions in the Bitcoin system over a period of time and recording the formation of new blocks on the blockchain. These miners are called miners. 2. Mining is a bookkeeping process, miners are bookkeepers, and the blockchain is the general ledger. 3. The accounting rights of the Bitcoin system are decentralized, that is, every miner has accounting rights. Miners who successfully seize the accounting rights will receive new Bitcoin rewards from the system. Mining is the process of producing Bitcoins.

1. What does mining mean?

Ancient mining can be traced back to the selection of stone materials in the Stone Age. Later, with the rise of the metallurgical industry, mining and mineral processing technology gradually developed. This article introduces the aspects of open-pit mining, underground mining, tunnel support, rock crushing, tunnel ventilation, lighting, drainage, lifting and mineral processing in ancient China.

Open-pit mining There are many surface outcrops, slopes or residual deposits of various metal veins or ore bodies. Therefore, open-pit mining became an important mining method in ancient times. Open-pit mining can be divided into excavation method and soil reclamation method.

2. Mining is the name for accumulated income from activities in Bitcoin.

Mining was brought about by the recent popularity of Bitcoin. Bitcoin is a virtual currency that can be exchanged for real currency. One of the ways to obtain Bitcoins on the Internet is to participate in related activities every day. These activities, like mining in online games, require slowly accumulating wealth in exchange for Bitcoins.

VI Top Ten Blockchain Mining Apps

The ranking of mobile mining apps is as follows:

1. ETH mobile mining mine. ETH mobile mining is a way to make money through mobile miningSoftware, users can trade with confidence in this software, all transaction information is open and transparent, and the latest monetary policy can be seen every day.

2. HBC environmental protection chain. HBC Environmental Chain is a very easy-to-use investment and financial management app. Users can redeem environmental coins by completing mining tasks, and the mining gameplay provided here is very simple.

3. Fire brush horizon mining. Fire Brush Vision is a brand new blockchain money-making platform, where users can directly receive tasks and complete tasks to obtain rewards. There is no need to invest or energy, and they only need to use their spare time to purchase mining machines. That's it.

4. ABEL trading platform. A professional mobile phone mining software, users can easily obtain a variety of digital currencies here, and can also conduct various digital currency transactions here at any time.

5. Secoin Star Ecology. A very easy-to-use mobile mining software that provides users with a very convenient and easy-to-use mining machine. They only need to use some daily rest time to obtain a variety of digital currencies.

Mobile mining is very simple. Just download the APP and register an account. The ways to obtain rewards are similar. If you want to use this mobile mining APP and increase your computing power, you must use facial recognition, Alipay, and Taobao authorization. , Xuexin.com authorization, operator authorization, JD authorization, binding GXS wallet, backup wallet, inviting friends, and checking in online every day.

Possible disadvantages of mobile phone mining:

1. Stealing user privacy. Some apps pretend to be mining, but are actually collecting user information and C-side traffic, which may cause problems such as user information leakage.

2. Greatly shorten the life of mobile phones. For mobile phones with mining systems installed, apps quickly drain battery power, generate excessive heat, or put unnecessary pressure on device resources.

3. The most important thing is that mobile phone mining is actually mining for candy, and mainstream coins cannot be mined. It is difficult to mine mainstream currencies with mobile phones. Nowadays, mainstream currencies such as Bitcoin and Ethereum cannot be mined with the computing power of mobile phones.

Ⅶ Competition among emerging public chains, who will be the first to rival Ethereum?

This video was jointly produced by Baize Research Institute and Tencent News.

Due to the explosive growth of the DeFi and NFT fields on the Ethereum public chain, it is difficult for Ethereum's performance to carry greater market demand, but the official solution of Ethereum 2.0 is progressing slowly. While everyone is concerned about whether Ethereum can surpass Bitcoin, Ethereum's "competing products" are also launching a powerful offensive against Ethereum through performance, smart contract applications, audience groups, etc. So who will be the first to compete with Ethereum?

Hello everyone, welcome to Baize Research Institute. Starting from this episode, let’s talk about the recently popular emerging public chains. First of all, to understand the public chain that this series will talk about, we must first understand some basic concepts. What is blockchain? what isPublic chain? Why are so many emerging public chains rising to challenge Ethereum, the most popular blockchain?

The concept of blockchain was first proposed by Satoshi Nakamoto, the creator of Bitcoin, in 2008. Conceptually, blockchain is a method of storing data in blocks. Distributed ledger technology that is sequentially connected and cryptographically guaranteed to be non-tamperable and non-forgeable. Simply put, blockchain technology can achieve openness, transparency, non-tampering, non-forgery and traceability of all data information in the system without the need for third-party participation.

For ease of understanding, in essence, the blockchain is a database. But this database is a bit special. It is a distributed and decentralized database. Everyone knows about databases, but how do we understand distribution and decentralization?

Let me take myself as an example. I, Heimi, used to live in a haze, never knowing how much I earned and where I spent it. Later, an expert gave me some advice, saying that you can't do this. You must learn to keep accounts, figure out your income and expenses, and learn to plan, so that your life will be better and better. Once I hear it makes sense, I'll keep the account.

I started to record every day, how much I earned in a month, how much I spent, and how much was my balance. I wrote them all down. The notebook I used to keep accounts can be called a database, and each item written in the notebook was written down. The income and expenditure items are the data in the database.

But now I am doing accounting alone and have only one database. One day my laptop was burned by fire, the account book was gone, and the database was gone.

Ever since, I mobilized my parents to keep accounts with me. When checking, we will use most of the same records as a consensus. In this case, there will be three ledgers keeping accounts at the same time. Even if one day, my laptop is burned down, their laptops will still be there, and the data will not be lost. This is a distributed, decentralized ledger, and its The advantage is that the data is safe, there is no unique center, and it doesn’t matter whose data is lost.

In order to facilitate reconciliation, the three of us check the daily income and expenditure records and record them on another piece of paper. We can call this piece of paper a block. We record one piece of paper per day and one block. Then a block is recorded, and when connected together, it is called a blockchain.

Okay, let’s summarize it here. First, the accounting notebook is a database. Second, it is distributed and decentralized. The three ledgers are jointly recorded. If the records are the same, then they are all valid; if there are differences, then the majority of the same records will prevail. The three ledgers are in the hands of three people and cannot be destroyed at the same time. The data is absolutely safe.

Such a distributed, decentralized ledger or database is a blockchain.

Ok, after understanding the concept of blockchain, let’s understand the different types of blockchain. According to the rules of node access, blockchain can be divided into: public chain, private chain, and alliance chain.

A public chain can also be called a public chain. The code is open source and decentralized. On this kind of blockchain, any individual or organization in the world can initiate transactions at any time, and anyone can Can participate in the blockchain consensus. Even the founder or development team of this public chain cannot infringe on the rights of users. The public chain is the earliest blockchain and the most widely used blockchain. For example, the well-known cryptocurrencies such as Bitcoin and Ethereum are based on the public chain.

Alliance chain, also called joint blockchain, is an organization that designates multiple pre-selected nodes as bookkeepers. The generation of each block is jointly decided by all selected nodes. Others Admitted nodes or users can participate in transactions, but will not be involved in the accounting process. Therefore, the alliance chain can actually be called a "hyperledger".

A private chain can also be called a private chain. As the name suggests, it only uses blockchain technology for accounting. It can be a company or an individual, with exclusive rights to this blockchain.

It should be noted that investment in cryptocurrency is strictly prohibited in our country. This video is mainly to introduce readers to the development trends in the field of blockchain technology. It is not recommended that everyone participate in currency speculation.

In the past few years, the development pace of public chains has been accelerating, and hundreds of large and small public chains have emerged. The more well-known public chains include: BTC, ETH, BSC, Polkadot wait.

Due to the explosive growth of the DeFi and NFT fields on the Ethereum public chain, it is difficult for Ethereum's performance to support greater market demand. Ethereum is the first but not the only blockchain to support smart contracts. Although the development team is aware of the performance limitations and is seeking to improve it through the development of Ethereum 2.0, progress has been slow. While everyone is concerned about whether Ethereum can surpass Bitcoin, Ethereum’s “competing products” are also launching a powerful offensive against Ethereum through performance, smart contract applications, audience groups, etc. After all, who doesn’t want to replace Ethereum? Ethereum has become the mainstream operating system in the entire crypto world, which includes various Layer 2 solutions and some emerging public chains that have expanded the capacity of Ethereum in recent years.

In the second half of this year, it can be said that a "public chain battle" broke out in the encryption industry. Solana public chain fired the first shot, and then Avalanche public chain announced a total liquidity of US$180 million. The mining plan enables multiple leading DeFi projects to be integrated into Avax; the Fantom public chain invested 370 million FTM tokens to launch an ecological incentive plan; some leading DeFi projects jointly invested US$100 million to support the development of the Celo public chain. Rather than a comparison between emerging public chains such as Solana, Terra, and Avalanche, it is better to say that emerging public chain groups are challenging their predecessors such as Ethereum, BSC, and Polygon. From this point of view, the structure of the public chain market has completely changed.

In fact, if you think about it carefully, the rise of emerging public chains such as Solana, Terra, Avalanche, and Fantom is not because of the so-called "blockchain performance surpassing Ethereum." The real reason behind it is actually cross-chain The popularity of bridges in various public chains will be discussed later.

If the future blockchain world is really the coexistence and interconnection of multiple chains as industry experts say, then the story of emerging public chains is far from over. Some other star public chains have also emerged in this public chain battle, such as Celo, Near, Algorand, Harmony, etc. Their comprehensive strength is not inferior and they are gaining momentum.

Ⅷ What does blockchain mining mean

2009 Satoshi Nakamoto Invent Bitcoin, and set the number of Bitcoins to be only 21 million. Join the Bitcoin network, participate in the production of blocks, and provide proof of work (PoW) to obtain rewards from the Bitcoin network. This process is mining.

The concept of "mining" is taken from the existing concepts in our real economic life, such as gold mining, silver mining, etc. Because minerals are valuable, people are driven to pay labor force. dig.

Another important point of Bitcoin mining is that the miners participating in mining recognize the value of Bitcoin, and there are people in the market who are willing to spend money on the Bitcoins they mine. So, Bitcoin mining makes sense.

Bitcoin’s Currency Characteristics

1. Decentralization

Bitcoin is the first distributed virtual currency. The entire network is composed of users and there is no central bank. Decentralization is the guarantee of Bitcoin’s security and freedom.

2. Circulation around the world

Bitcoin can be managed on any computer connected to the Internet. Anyone can mine, buy, sell or receive Bitcoin regardless of location.

3. Exclusive ownership

Manipulating Bitcoin requires a private key, which can be isolated and stored in any storage medium. No one can obtain it except the user himself.

4. Low transaction fees

Bitcoins can be remitted for free, but a transaction fee of about 1 bit cent will ultimately be charged for each transaction to ensure faster transaction execution.

5. No hidden costs

As a means of payment from A to B, Bitcoin does not have cumbersome limits and procedures. You can make the payment by knowing the other party's Bitcoin address.

6. Cross-platform mining

Users can explore the computing capabilities of different hardware on many platforms.
