② Shenzhen Taxation: Launched 108 enterprise-friendly service initiatives

You can directly listen to 54 financial statement templates for management (with explanations and formulas) to help you navigate the workplace! Restore 3, and all 50 sets of super-famous accounting formulas are prepared for you!
The reporter learned yesterday that the Shenzhen Municipal Taxation Bureau promulgated the "State Administration of Taxation Shenzhen Municipal Taxation Bureau's Action Plan to Further Optimize the Tax Business Environment" (hereinafter referred to as the "Plan"), and accurately launched 108 specific measures. We will vigorously create a stable, fair and transparent business environment and comprehensively serve the high-quality economic development of Shenzhen.
It is reported that these 108 specific measures to optimize the business environment cover 17 aspects in 4 categories, including shortening tax processing time, reducing tax burden, optimizing after-tax processes, and standardizing tax laws, and will be gradually implemented in three years. , of which 45 were launched before the end of 2018.
Li Wei, deputy director of the Shenzhen Municipal Taxation Bureau, said that he hopes to comprehensively improve tax collection and management functions and the quality of taxation services over three years, striving to achieve the overall goals of streamlining administration and delegating power, regulatory reform and service optimization. Among them, the implementation of using blockchain to developThe 28 measures, including the "one-click appeal" and the newly added tax refund function for wrongly collected and overpaid taxes, are all launched by Shenzhen and cover tax filing, tax handling procedures, invoice reform, "one network, One door, one time" reform, communication and communication, information sharing, business models, judgment and processing and other aspects.
Ma Xingkeng, the legal representative of Shenzhen Yujin Technology Co., Ltd., told reporters that in the past, if there were defects in the complaint and overpayment of taxes was made by mistake, one could only go to the front desk of the tax office for correction and tax refund. The newly promulgated reform measures have added online correction complaints and tax refund functions for incorrect tax collection and overpayment, so taxpayers can save themselves the trouble of visiting the tax bureau.
According to statistics, among the 108 measures launched in the "Plan", there are 77 measures to shorten tax collection time, accounting for the highest proportion, reaching 71%, highlighting the Shenzhen tax department's efforts to improve tax collection efficiency and communicate tax collection points. Look carefully.
Ning Jing, deputy director of the Taxation Service Department of the Shenzhen Municipal Taxation Bureau, told reporters that these measures are comprehensive and complementary and will comprehensively improve the profitability of taxation. It is reported that the 77 tasks to shorten the tax collection time include simplifying the tax processing process, simplifying the forms and documents, simplifying tax appeals, and information sharing.
For example, in terms of simplifying the tax processing process, it is determined that general VAT taxpayers rated as A, B, and C can simplify the monthly filing to quarterly filing; in terms of simplifying the tax filing process, general tax payers Small-scale taxpayers who have not incurred output tax or output tax, and small-scale tax payers who are not subject to examination and approval do not need to file a complaint when they have not incurred taxable income; in terms of simplifying certification notices, all kinds of tax-related and fee-related declarations have been comprehensively sorted out, and gradually become more and more effective. Electronic tax-related notices.
According to the "Plan", the Shenzhen Municipal Taxation Bureau will simplify the business registration process and implement "package" services for new taxpayers. By strengthening cooperation with the industrial and commercial departments, market entities will be able to complete the registration process when creating and filing with the industrial and commercial departments. Comprehensively collect tax-related information from taxpayers to further lower the threshold for employment and entrepreneurship.

③ 108 essential knowledge points for getting started with blockchain

Author: Kong Lin

61. Trapped

Expect the currency price to rise, but unexpectedly the currency price falls after buying; or expect the currency price to fall, but unexpectedly the currency price rises after selling

62. Unwinding

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

63. Going short

After selling Bitcoin because of the bearish market outlook, However, the currency price continued to rise, and I failed to buy in time, so I failed to make profits

64. Overbought

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

65. Oversold

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

66. Lure bulls

The currency price has been consolidating for a long time and is more likely to fall. Most of the short sellers have sold Bitcoin. Suddenly the short side pulls up the currency price and induces Many parties thought that the price of the currency would rise and bought one after another. As a result, the short parties suppressed the price of the currency and locked up the long parties.

67. Short-selling

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

68. What is NFT

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

69. What is the Metaverse

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

70. What is DeFi

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

71. Who is Satoshi Nakamoto?

72. Bitcoin is different from Q Coin

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

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

73. What is a mining machine?

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

74. What is quantitative trading?

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

75. Blockchain asset over-the-counter trading

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

76. What is a timestamp?

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

77. What is a blockchain fork?

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

78. Soft fork and hard fork

Hard fork means that when the Bitcoin code changes, the old nodes refuse to accept the blocks created by the new nodes. Blocks that do not comply with the original rules will be ignored, and miners will follow the original rules and create new blocks after the last block they verified. A soft fork means that old nodes are not aware of the changes to the Bitcoin code and continue to accept blocks created by new nodes. Miners may work on blocks they have no understanding of, or validation of. Both soft forks and hard forks are "backwards compatible" to ensure that new nodes canVerify 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 an information-based A computer protocol that spreads, verifies or executes a contract. 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.

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 the production relationship is the labor exchange and consumption relationship. 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. It is the most popular topic and investment trend in 2017, and the country launched a regulatory plan on September 4. Speaking of ICO, people will think of IPO, and the two are essentially different.

99. Five characteristics of digital currency

The first characteristic: decentralization

The second characteristic: having open source code

The third feature: independent electronic wallet

The fourth feature: constant issuance

The fifth feature: global circulation

100.What is decentralization?

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

100. What is measurement (scarcity)?

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

101. What is open source code?

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

102. What is anonymous transaction? Private wallet private?

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

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

105. Digital Currency Industry Chain

Chip manufacturers, mining machine manufacturers, and mining machine agents mine and export to exchanges for retail investors to speculate in coins

④ 108 knowledge points for getting started with blockchain

108 essential knowledge points for getting started with blockchain

(Welcome to communicate with the same channel)

1. What is a blockchain

Packing together the information of multiple transactions and the information indicating the block, 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 refers to "smart contracts", which are a set of contract systems that can be automatically executed and written according to their own needs. Application layer: Applications on the blockchain, similar to mobile apps. Former Distributed Storage R&D Center

13. Timestamp

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

14. Block/block header/block body

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

15. Merkle tree

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

16. What is expansion?

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

17. What is a chain?

Each block will save the previousThe hash of the block creates a relationship between blocks, and 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 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 we were looking for finally found a random number that met the conditions: the value after hashing is higher than the hash value of the preset difficulty value.If the hash value is small, then the mining is successful. The node can broadcast the block to neighboring nodes. When the neighboring node receives the block, it performs the same operation on the above six fields, verifies compliance, and then broadcasts it to other nodes. , other nodes also use the same algorithm for verification. If 51% of the nodes in the entire network are successfully verified, this block will be truly "mined" successfully, and each node will add this block to it. After a block, delete the list in the block that is the same as its own record, and repeat the above process again. 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’s 10 minutes.

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

29. Verification

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

30. Transaction broadcast

The node sends information to other nodes through the network.

31. Mining fees

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

32. Transaction confirmation

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

33. Double transaction

That is, I have 10 yuan, I use the 10 yuan to buy a pack of cigarettes, and then instantly use the 10 yuan that has not yet been paid. againBought a 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

42. Full position

All funds are bought Enter Bitcoin

43. Reduce the position

Sell some of the Bitcoins, but not all of them

51. Long (long)

The buyer believes that the currency price will rise in the future, buys the currency, and waits for the currency price to rise. Sell at a high price and take profits

52. Short position (short selling)

The seller believes that the currency price will fall in the future and sells the currency he holds (or borrows currency from the trading platform) After the currency price drops, buy at a low price and take profits

53. Open a position

Buy virtual currencies such as Bitcoin

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.In games and services, the value of Q coins is entirely based on people's trust in Tencent.

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.

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 requires the support of the Bitcoin community.If the Bitcoin community cannot reach an agreement, the blockchain is likely to 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".

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

97. The difference between big data and blockchain

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

⑤ Blockchain token + decentralization, realizing data confirmation and value redistribution

In "The Real Business Opportunities of Blockchain", the author mentioned this An example of a pass application is related to travel planning.

Tokens in a centralized digital environment

The above diagram describes the role of tokens in a centralized solution, and the process is relatively complicated.
1. In the real world, travelers need to share this information with travel agencies. On the Internet, they can use templates provided by online travel sites. These websites function like data brokers: they can use their accumulated customer information to attract marketers from various segments of the travel industry and generate revenue through marketing services. In a tokenized environment, information about traveler plans would be passed to one of the data brokers.
2. After receiving the passenger's data, the data broker will collect the information and tokenize the information to create a data token. Wallets managed by data brokers will also collect tokens issued by service providers.
3. Passengers start paying to use services. They will use the tokens issued by the service provider during the trip, such as for checking into and spending money at the hotel.
4. The pass is still useful during the traveler’s vacation. For example, when a traveler decides to take a hotel's recommendation to stay an extra night, they can receive additional tokens for room service, bar drinks, or room upgrades. In these scenarios, the pass can incentivize travelers to stay in the service provider’s business ecosystem.
5. Whether during or after vacation, travelers can upload photos, restaurant reviews and itineraries to multiple social media, which will also involve data brokers.
6. Data brokers coordinate with service providers to reward customers for posting reviews through free accommodation or free meal passes to encourage word-of-mouth spread. Travelers can save these passes for their next trip, use the pass elsewhere where the service provider offers services, or share the pass via a digital wallet with friends who are traveling to the same destination.

What will be the effect if we switch to a blockchain solution?
This solution ensures the decentralization of customer data, allowing participants to keep data locally and selectively share it with third parties. Passengers can customize the parameters on how to use the pass, and under the configuration of these parametersHow to use smart contracts to obtain tokens.

Instructions for token circulation in a complete blockchain solution

In this case, passengers can coordinate on their own and share relevant data in a tokenized form. Travel service providers, such as airlines and hotels, simultaneously obtain quotes through digital wallets or other interfaces accessible only to travelers. If these interactions are coordinated on a blockchain-enabled platform, travelers will have the opportunity to choose to share data across multiple platforms, thereby obtaining more and better offers. Travelers as hubs gain sovereignty over their data.
In a decentralized model, service providers trusted by consumers can better set their own terms. These companies can negotiate pricing rather than having to base it on what the platform requires. Such freedom encourages participation and innovation among service providers. Therefore, decentralization of data monetization is conducive to market competition.

From the above example, the addition of the decentralized model of tokens has brought major changes to the business world - that is, data assets are owned by individuals, data is valuable, and the price is determined by consumers. Sure! Such a business model is bound to have an impact on existing Internet platforms. In the first picture, almost all the characters revolve around the data service provider, that is, the Internet platform. In the second picture, individuals have become the protagonists of this business world, and data service providers have been marginalized. Well, now that this model has appeared in people's minds, some people will try out this business model. Let us look forward to seeing such new business models in the future.

⑦ Tencent sued Lao Ganma who is the biggest beneficiary. The article will explain to you "with indicators"

Regarding Tencent suing Lao Ganma for owing advertising fees, Lao Ganma is It is said that Tencent suffered a fraud. This shocking reversal should be enjoyed by everyone.

When I first learned that Tencent was suing Laoganma, I thought Tencent would definitely win. You must know that Tencent’s legal department can be called “Nanshan Pizza Hut” (“Nanshan” refers to Nanshan District, Shenzhen, Tencent’s headquarters Located in the Nanshan District High-tech Park, a major taxpayer, "Pizza Hut" refers to the 100% winning rate of Tencent Legal Department's lawsuits in Nanshan District Court, which shows how powerful Tencent's Legal Department is.)

Who knows what will happen? In a shocking reversal, "Nanshan Pizza Hut" was defeated by Godmother.

On July 1, Guiyang Public Security Shuanglong Branch reported that three people forged the seal of Laoganma Company and signed a cooperation agreement with Tencent by pretending to be the manager of the company’s marketing department. Currently, the three people have been detained.

After the announcement, Tencent updated a news on station b, "The chili sauce at noon today suddenly lost its flavor."

Don’t just watch the excitement. In the "Tencent sues Lao Ganma" incident, the biggest winner of this subject has already appeared (or it may not be the "Lao Ganma" who just picked up the advertisement for free)

According to the Guiyang police report, three people forged the seal of Laoganma Company and signed an agreement with Tencent by pretending to be the manager of the company’s marketing department. Their purpose was to obtain the online game gift pack code given by Tencent in promotional activities. Later, he illegally obtained financial benefits through reselling on the Internet.

Alipay later expressed on Weibo that "Tencent sues Laoganma" incident that swept the screen, "I hope there will be no fake seals in the world", and accompanied it with the July 2019 "Alipay announced the use of blockchain Solve the problem of "fake contracts and carrot seals" in the supply chain.

In the field of supply chain finance, in recent years, the trick of forging contracts and falsifying accounts receivable to obtain factoring financing has been repeatedly performed, with the amount involved in a single case often reaching hundreds of millions. Blockchain is regarded by the industry as a technical solution to prevent supply chain financial risks.

It is understood that Ant’s blockchain patent application layout revolves around core issues in the commercial field, such as payment, finance, insurance, and security. Among them, "Double Chain Link" is a supply chain collaboration network developed by Ant Financial based on blockchain technology. It "uploads" the entire life cycle of core enterprises' accounts payable confirmation, circulation, financing, and clearing to the chain. It not only broadens the The financing channels for small, medium and micro enterprises also improve the capital utilization efficiency of core enterprises in the supply chain, achieving a win-win situation.

In terms of related companies, according to the theme library blockchain and other sections,

Donggang Shares: signed a partnership framework agreement with Ant Blockchain, focusing on "blockchain + tax" , "blockchain + finance", "blockchain + finance" and other fields to establish long-term and in-depth cooperation.

Yi Lianzhong: Cooperating with Ant Financial through blockchain in vaccine traceability and prescription leakage, no products have been launched yet. Recently, a subsidiary of Ant Financial invested in a subsidiary of Yilianzhong.

Stock trading requires learning to think independently, such as the sector linkage during this personal leave. (Just refer to the news page, I won’t explain the reason)

That’s it for this issue’s inner tube. No, I forgot to mention the good indicators.

⑨ How to learn blockchain knowledge

When blockchain technology becomes more and more popular, many people want to learn because they are unfamiliar with it, but I don’t know where to start learning.

It’s like you have just paid the fee and have just become a disciple of a martial arts expert.

“Master, I want to become a martial arts master. Where should I start? Are you ready to learn?"

Your master pushed you out the door, "If you want to learn the dog-beating club, go to Hong Qigong, if you want to learn the Six Meridians Divine Sword, go to Prince Duan, if you want to learn the Anran Xiaohun Palm, I want to go to Yang Guo, I want to learn the Sunflower Book, I want to go to Dongfang Bubai, I want to learn the Nine Swords of Loneliness, I want to go to Feng Qingyang.

It is really the master who leads you in, and practice depends on each individual.

From then on, master and disciple were just strangers.

Today, I am still silently silent for thousands of years, hiding in this planet without calling for thousands of years.

On the way to learn blockchain, you must keep your eyes open and find a reliable blockchain teaching class.

Then you can enter the blockchain content platform and learn while practicing, the effect will be better!

⑩ How to understand blockchain

Buy one or two books about blockchain. After reading it, you will have a general understanding of blockchain technology and development prospects. A general understanding. But you should also pay attention to real-time developments. Huobi China has done a good job in this regard. It has weekly, monthly and other industry analysis reports, which are relatively authoritative in the country.
