『二』 Is the Beidou World Chain a national form?

Beidou is a national key project, and the Beidou World Chain is similar to a pyramid scheme organization.

China's BeiDou Navigation Satellite System (BDS) is a global satellite navigation system independently developed by China. It is the fourth mature satellite navigation system after the American Global Positioning System (GPS), the Russian GLONASS, and the European Galileo satellite navigation system.

The Beidou satellite navigation system consists of three parts: the space segment, the ground segment and the user segment. It can provide high-precision and high-reliability positioning, navigation and timing for all types of users around the world, all day and night. service, and has short message communication capabilities. It has preliminary regional navigation, positioning and timing capabilities, with a positioning accuracy of 10 meters, a speed measurement accuracy of 0.2 meters/second, and a timing accuracy of 10 nanoseconds.



(2) Beidou World Blockchain Information Search Extended Reading

On November 5, 2017, China’s third-generation navigation satellite was successfully launched, which marked the official start of China’s construction of the “Beidou” global satellite navigation system.

At 7:52 on August 25, 2018, my country successfully launched its first satellite with the Long March 3B carrier rocket (and the Yuanzheng 1 upper stage) at the Xichang Satellite Launch Center in the "one rocket and two satellites" mode. Thirty-five or thirty-six Beidou navigation satellites, two of which belong to medium earth orbit satellites, are also the eleventh and twelfth networking satellites of my country's Beidou-3 global system. [1] At 22:07 on the evening of the 19th, Beijing time, China successfully launched the 37th and 38th Beidou navigation satellites using the Long March 3B carrier rocket and the Yuanzheng 1 upper stage at the Xichang Satellite Launch Center in a "one rocket and two stars" method. . These two satellites are medium earth orbit satellites and are the 13th and 14th networking satellites of China's Beidou-3 global system. The two Beidou navigation satellites are also equipped with standard equipment of the International Search and Rescue Organization for the first time, which will provide distress alarm and positioning services to users around the world.

『三』What exactly is Beidou Shilian?

Beidou Shilian is a point-based pyramid scheme. If you don’t believe it, you can download Sky Eye to check whether this company has been fined for abnormal operations. I know that there are still people who invest money foolishly. This is really brainwashing. There are so many BD members in their hands. Who wants it? No one wants the price to be high. What’s the use of just a number? When registering the BD pass, a company called Beidou Holdings Group Co., Ltd. signed an agreement with the user. Through "Tianyancha" and "Qichacha", it was checked that this is a Hong Kong company. The WeChat group claimed that Beidou Shilian is affiliated with Beidou Industry Group. And they work in the same building. According to the query, Beidou Industry Group Co., Ltd. is also a Hong Kong company. The largest shareholder of Beidou Shilian is Chengdu Dongfang Caiyuan Business Service Co., Ltd., which is a private company, but it advertises that Dongfang Caiyuan belongs to Dongfang Finance, which is affiliated to the Ministry of National Security and a military industrial enterprise. This is obviously deceiving! All satellite navigation applications in my country are certified by the China Satellite Navigation and Positioning Application Management Center. According to its official website, none of the above companies exist. In addition, Beidou Shilian Internet of Things Technology Co., Ltd. was confiscated 18,289,424 yuan of illegal property and fined 1.8 million yuan by the Market Supervision and Administration Bureau of Mengyin County, Shandong Province on May 19, 2018 for being suspected of organizing and leading pyramid schemes. Shaanxi Reik Biotechnology Co., Ltd., another company of the legal person Zeng, was listed as an "Enforcement Enterprise" by the court. Zeng was also included in the "Restricted Consumer Personnel" blacklist due to a debt of 921,500 yuan. This can be found in the "China Enforcement Information Check on the "Open Network".
On September 4, 2017, the People's Bank of China, the Cyberspace Administration of China, the Ministry of Industry and Information Technology, the State Administration for Industry and Commerce, the China Banking Regulatory Commission, the China Securities Regulatory Commission, and the China Insurance Regulatory Commission jointly issued an announcement on preventing token issuance financing risks. The announcement stated that “no organization or individual may illegally engage in token issuance and financing activities.” BD pass is actually a token.Just to change the concept, the state explicitly prohibits it, and I will never buy it in the future!

『四』Is WorldLink Certificate initiated by the state?

It is not initiated by the state, it is a private enterprise.

The World Connect Certificate is a certificate for developing countries around the world that is directly linked to and anchored by its superior natural resource value, and its sovereign encrypted digital assets are issued on the blockchain platform.

WorldLink Certificate uses blockchain technology and thinking to promote the rapid economic development and financial independence of developing countries around the world, supports developing countries in developing the digital economy, enjoys the dividends of the changes in the global digital economy era, and promotes Global economic integration and balanced development.

(4) Beidou Shilian Blockchain Information Search Extended Reading:

Blockchain originated from Bitcoin on November 1, 2008. A person who calls himself Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which explains the electronic cash system based on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc. The architectural concept marks the birth of Bitcoin.

Two months later, the theory came into practice, and on January 3, 2009, the first genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block number 0 to form a chain, marking the birth of the blockchain

Beidou Shilian Company’s philosophy:

Big data, cloud computing and the Internet of Things can be said to be the hottest "troika" in the IT field. The three complement each other and are both connected and different. From the perspective of conceptual division: Big data represents the information layer of the Internet. It is a data collection so large that its acquisition, management, and processing greatly exceed the capabilities of traditional database software tools.

The meaning of cloud computing has evolved to this day, and it refers more to the integration and optimization of underlying data basic resources and service-basedBusiness model for providing IT resources (IaaS, PaaS, SaaS).

The Internet of Things is a type of information technology and can be regarded as the "Internet of things connected". As an extension of the Internet, it uses communication technology to connect sensors, controllers, people and things in new ways. Connected together, the purpose is to achieve information connection and management control. < /p>

1. What is a blockchain

The information of multiple transactions and the information indicating the block are packaged together. The verified package is the block.

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

2. What is Bitcoin

The concept of Bitcoin was proposed by Satoshi Nakamoto in 2009, with a total number of 21 million. The Bitcoin chain generates a block approximately every 10 minutes, and this block is mined by miners for 10 minutes. As a reward to miners, a certain number of Bitcoins will be issued to miners, but this certain number is halved every four years. Now it's 12.5. If this continues, all Bitcoins will be available in 2040.

3. What is Ethereum

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

4. Distributed ledger

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

5. What is quasi-anonymity?

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

6． What is open transparency/traceability

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

7. What is tamper-proof

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

8. What is anti-DDoS attack

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

9. Definition of main chain

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

10. Single chain/multi-chain

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

11. Public chain/alliance chain/private chain

Public Chain: Everyone can participate in the blockchain

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

Private chain: Writing and viewing permissions are only 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, is a data structure for storing data., the bottom layer is the original data contained in all blocks, and 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, forming a new layer, and then goes 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 blocks

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

22. Uncle block

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

23 replay attack

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

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

28. Mining difficulty and computing power

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

p>

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

29. Verification

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

30. Transaction broadcast

The node sends the transaction to other nodes through the network.Send information.

31. Mining fees

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

32. Transaction confirmation

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

33. Double transaction

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

34. UTXO unspent transaction output

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

35. Transactions per second TPS

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

36. Wallet

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

37. Cold wallet/hot wallet

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

38. Software Wallet/Hardware Wallet

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

39. Airdrop

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

40. Mapping

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

41. Position

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

42. Full position

Buy with all funds bitsCoin

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

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 then buying Bitcoin at a loss

61. Holding up

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

62. Unwinding

After buying Bitcoin, the currency price fell, causing a temporary book loss, but then the currency price rebounded and the loss was reversed for 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 At a certain low point, 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 short sellers have sold bits currency, suddenly the short side pulled up the price of the currency, inducing many parties to think that the price of the currency will rise, and they bought one after another. As a result, the short side suppressed the price of the currency, causing the long parties to get stuck

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

< p> 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, mainly used for digital purposes. The difference between asset confirmation and transfer and digital currency is that it is unique and indivisible. In essence, it is a unique digital asset.

69. What is the Metaverse

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

70. What is DeFi

DeFi, the full name is Decentralized Finance, which is "decentralized finance" or "distributed finance". "Decentralized finance", as opposed to traditional centralized finance, refers to various financial applications established in open decentralized networks. The goal is to establish a multi-level financial system based on blockchain technology and cryptocurrency. As a basis, re-create and improve the existing financial system

71. Who is Satoshi Nakamoto?

Satoshi Nakamoto is the developer and founder of Bitcoin. Satoshi Nakamoto published the Bitcoin white paper on November 1, 2008, and mined Bitcoin for the first time on January 3, 2009. Whoever can use the Bitcoin in the genesis block is Satoshi Nakamoto himself, so who Is it Satoshi Nakamoto? There have been many "Satoshi Nakamotos" in history: In 2013, someone revealed that Mochizuki Shinichi, who had made outstanding contributions in the field of mathematics, was Satoshi Nakamoto, but no direct evidence was provided. In 2014, hackers broke into the email address used by Satoshi Nakamoto and found the owner of the email, Dorian Nakamoto.akamoto), and then Dorian said that he only obtained the email address and password by chance and was not Satoshi Nakamoto. In 2016, Craig Wright said that he was Satoshi Nakamoto and could provide Satoshi Nakamoto's private key. But later, Wright withdrew his statement because he could not face everyone's doubts.

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?

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

77. What is a blockchain fork?

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

78. Soft fork and hard fork

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

79. Classification and application of blockchain projects

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

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 is very low. You can even copy the Bitcoin code and modify some parameters.to generate a brand new blockchain.

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)

Blockchain Types

1. Public Area Blockchain

Public BlockChains means: any individual or group in the world can send transactions, and the transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. .

2. Consortium (Industry) Blockchain

Industry Blockchain (ConsortiumBlockChains): Multiple pre-selected nodes are designated as bookkeepers within a certain group. Each block The generation is jointly decided by all pre-selected nodes (the pre-selected nodes participate in the consensus process). Other access nodes can participate in transactions, but do not participate in the accounting process.

3. Private Blockchain

Private Blockchains (PrivateBlockChains): Only use the general ledger technology of the blockchain for accounting. It can be a company or an individual. Exclusive writing permissions for this blockchain. This chain is different from other distributed storage solutions.Big difference.
