㈠ Now that express delivery is so developed, would you consider buying groceries online
Express delivery is also very developed now. Many things can be purchased online and delivered by express delivery. Many people rely on the takeout industry to their own homes, including the takeout industry, because of the convenience and speed of delivery. However, you still have to think about it when buying food online, because the vegetables we eat are all fresh and not Fresh vegetables are very harmful to the human body.
So, even if express delivery is so developed now, I will no longer consider buying food online, because there are many varieties of vegetables in the vegetable markets around us, and the supply There is also a great possibility to choose by yourself. With such a convenient market, there is no need to buy vegetables online.

㈢How did Bitcoin happen, how it was created, and what its role is
The following content is from: http://bitcoin.org/zh_CN/about< br />
Historical Background
Bitcoin was one of the first currencies to implement the concept of “cryptocurrency”. In 1998, Wei Dai first explained the concept of "cryptocurrency" on the cypherpunks mailing list. Built on the basic concept of money—a currency used in a given country or economyPayment for goods, services, debt repayments, or any form of record. Bitcoin is a new form of currency. Its original design incorporates the idea of not relying on a central authority and using cryptography principles to control currency issuance and transactions.
In 2009, Satoshi Nakamoto (pseudonym) published the first Bitcoin specification and its proof of concept on the cryptography mailing list. At the end of 2010, Satoshi Nakamoto claimed that he had moved on to other matters and left the project. The creator of Bitcoin never revealed his true identity and simply left his invention to the world. To this day, the origins and motivations for Bitcoin’s invention remain a story steeped in mystery.
Since 2010, many developers have been working on this project, and the Bitcoin community has grown quickly. Between June and July 2011, Bitcoin suddenly received media attention, leading to massive buying. The resulting bubble caused Bitcoin's price to continue to fall throughout the second half of 2011. After that, the price of Bitcoin gradually and slowly returned to the height of 2011.
In order to regulate, protect and promote the development of Bitcoin, the Bitcoin Foundation was created on September 27, 2012. Today, with the increasing number of Bitcoin users, the Bitcoin economy is developing rapidly.
Technical Characteristics
Any network like Bitcoin has the following basic characteristics:
Bitcoin can be transferred between any nodes in the network.
Transactions are irreversible.
The use of blockchain avoids double consumption.
Transactions are propagated within seconds and verified within 10 to 60 minutes.
Transaction processing and currency issuance are uniformly executed through mining.
Receive Bitcoin at any time, whether you are online or not.
Economic Rules
The entire Bitcoin network jointly implements the following rules:
The total number of Bitcoins issued is approximately 21 million.
A Bitcoin can be split to 8 decimal places, for a total of approximately 21×1014 currency units.
Transaction costs are very low and most are free.
Statistics
The Bitcoin network has been running continuously for over 48 months. Bitcoin’s security features have developed dramatically over the past year. As of April 2013:
The longest blockchain has over 232,000 blocks.
One of the largest distributed computing networks in the world, with a computing power of more than 65 trillion hashes per second.
50,000 transactions are completed every day, totaling millions of dollars.
The total value of Bitcoin in circulation exceeds $1.3 billion.
There has been only one major security incident in the protocol, which was resolved in August 2010.

㈣ What are the sectors of stocks and what are the differences between sectors
Hello, the stock sector refers to certain companies that have certain relevant factors in the stock market. In this way One element names the section. As of October 30, 2019, there were approximately more than 3,700 listed companies in my country. Effective and reasonable classification of listed companies can help investors better focus on a certain industry, field or individual stocks. Especially when investors make investment choices, reasonable sector division can enable investors to more efficiently observe, compare, and analyze the business layout, operating conditions, financial status and other fundamental information of listed companies of the same type, which is an important factor for investors to make investment decisions. important basis for investment decisions.
Common stock sector classifications:
Industry sectors
According to the "Guidelines for the Industry Classification of Listed Companies" issued by the China Securities Regulatory Commission in 2012 (CSRC Announcement [2012] No. 31), each The industry classification results of listed companies will be announced at the end of the quarter, and listed companies will be divided into: A agriculture, forestry, animal husbandry and fishery; B mining industry; C manufacturing industry; D electric power, heat, gas and water production and supply industry; E construction industry ; F wholesale and retail industry; G transportation, warehousing and postal industry; H accommodation and catering industry; I information transmission, software and information technology services industry; J financial industry; K real estate industry; L leasing and business services industry; M science Research and technical services industry; N water conservancy, environment and public facilities management industry; O resident services, repair and other service industries; P education; Q health and social work; R culture, sports and entertainment industry; S comprehensive, a total of 19 categories , and 90 major categories subdivided. For example, as announced in the "Industry Classification Results of Listed Companies in the Third Quarter of 2019", the listed companies included in the oil and natural gas extraction industry under B mining industry are: Blue Flame Holdings, Worsch Holdings, Sinopec, PetroChina, and Intercontinental Oil and Gas and Guanghui Energy.
The China Securities Regulatory Commission’s basis for classifying industries of listed companies is: 1) When the proportion of operating income of a certain type of business of a listed company is greater than or equal to 50%, it will be classified into the industry corresponding to that business; 2) When the listed company does not If the proportion of operating income of a type of business is greater than or equal to 50%, but the income and profit of a certain type of business are the highest among all businesses, and both account for more than 30% of the company's total revenue and total profit (including this number), then the company Belong to the industry category corresponding to the business; 3) If the industry affiliation cannot be determined according to the above classification method, the industry classification expert committee of listed companies will judge the company's industry affiliation based on the company's actual operating conditions; if the affiliation is unclear, it will be classified as a comprehensive category.
In addition to the industry classification of listed companies announced by the China Securities Regulatory Commission,In addition, some institutions or stock software will also publish their own industry sectors.
Regional Segment
Regional Segment is divided into listed companies based on the region where they are located, such as: Beijing Segment, Shanghai Segment, Shandong Segment, etc.
Conceptual sector
There is no unified standard for conceptual sector, which is divided by various common factors of listed companies. The factors can be region, performance, technology, organization, policy, etc., for example:
Based on region Classification: Beijing-Tianjin-Hebei sector, Yangtze River Delta sector, Xiongan New Area sector, etc.;
Classification by technology: Blockchain sector, 5G sector, AR sector, VR sector, artificial intelligence sector, etc.;
By policy Classification: new energy sector, free trade zone sector, One Belt and One Road sector, rural revitalization sector, etc.;
Classification by performance: blue chip sector, ST sector, etc.;
Classification by index: CSI 300 sector, SSE 50 sector Sector, CSI 500 sector, etc.;
Classified by investors: social security sector, institutional sector, fund sector, QFII sector, etc.;
Classified by hot economy: new retail sector, internet finance sector , Internet of Things sector, e-sports sector, etc.
In addition to the above types of sectors, there are also different sectors divided by various concepts or characteristics, such as: Chinese header sector, yesterday's daily limit sector, equity transfer sector, etc. Concept sections are often hot topics for market speculation.

㈥ Internet celebrity teacher Li Yongle talks about Bitcoin and blockchain The principle is simple and easy to understand
Now that retail investors can no longer enter, bookmakers may use supercomputer mining. .
The technical principles of Bitcoin are not just used for this. In fact, they are similar to many survival wisdoms.
For example, why is Bitcoin not afraid of counterfeiting? Because Bitcoin counterfeiting requires one person to challenge the world. The problem is that if a person has so many mining machines, why should he violate the rules? In the rules, he You can get more benefits. . .
Everyone will follow the trend of longer blockchains, so you personallyIf you don't join this team, you will end up challenging the world alone. . .
The Dutch played with tulips, fried rubber in the late Qing Dynasty, and fried orchids in the last century. It’s all the same routine. Whoever takes over in the end is finished. Everyone is now betting on where the limit is and whether they can get there before it. Cash out. . .
(This teacher Li Yongle is considered the overlord among middle school teachers. He won the first prize in the National High School Mathematical Olympiad, the provincial champion in the High School Mathematical Olympiad, a double degree from Peking University, a master's degree from Tsinghua University, and the champion of the Beijing University Student Speech Contest. He is currently employed Yu is a physics teacher at the High School Affiliated to Beijing Renmin University and an independent producer of Xigua Video. This resume is so beautiful. This internet celebrity teacher has released hundreds of videos on Xigua. A small part of them are high school physics and mathematics courses, and most of them are about science squirrels. He will teach all-inclusive science popularization. The characteristic of this teacher is his clear logic and ability to explain complex issues in simple and easy-to-understand terms. One class lasts for fifteen minutes and fills two blackboards. It can be seen that he has prepared lessons well in advance, and his words are interesting and far-reaching. Like Tang Degang, as close as the bright moon back then, they all have this style. To be honest, I collected it first.)
In 2016, Lang Xianping, Shi Hanbing, host, three people discussed Bitcoin
>
Worth watching
Former BTCC CEO Li Qiyuan also came to the scene, and he and Lang Xianping exchanged blows.
Professor Lang believes that the person or institution that has accumulated the most Bitcoins is actually Satoshi Nakamoto. As long as he proposes a plan, the whole world will foolishly help him to speculate and appreciate the value. However, because This kind of virtual currency is on the edge of the system, so Satoshi Nakamoto does not dare to reveal his true identity
Finally, the host quoted the South Sea Bubble that caused Sir Isaac Newton to lose ten years of salary and leave the market with a loss. Newton once lamented: "I can accurately calculate the movement of celestial bodies, but I cannot predict the madness of human beings.
The best stories kill the most people... The reason why the South Sea Bubble deceived Newton was Because his story is really fascinating, very scientific, very realistic, and has its own way, just like Bitcoin now.
This is like rubber in the late Qing Dynasty, the rubber itself is naturally useful Industrial raw materials, but the price exceeds the value too much, it is still a bubble.
Which stock market crash in history was not a crazy bull market bubble...
But still every time There are speculators who take advantage of the fire, and at the same time, they don't forget to trick fools into taking over the market so that they can cash out. It's not that the speculators don't know that this is a bubble, they are speculating on whether they can take advantage of the fire and successfully cash out before the judgment day.
Let me just say a few points: 1. Anyone who drowns in water is someone who knows how to swim. After all, those who know how to mine are not illiterate. Newton was fooled by the South China Sea bubble, just like the famousThe joke is, when you meet a bear, you don’t need to run faster than the bear, you just need to run faster than the person behind you.
2. Bitcoin proposed by Satoshi Nakamoto is only a type of virtual currency. In addition, there are a large number of other blockchain virtual currencies with the same principle. The blockchain is indeed not a bubble, but the reason why Bitcoin is so hyped is that the price far exceeds the value, which is the so-called bubble. Blockchain is indeed an irreplaceable future trend, but Bitcoin is not. Bitcoin can be abandoned by the whole world at any time.
3 Satoshi Nakamoto’s Bitcoin system is completely based on a complex cryptographic algorithm. If this algorithm is cracked, or the speed of computers advances rapidly, such as quantum Computers, then the entire basis of Bitcoin's existence disappears, and there is no difference between it and the Zimbabwean currency.
4. Someone who is really optimistic about this thing would be so kind and publicize it to everyone, because he is afraid that there will be too few people competing with him to grab the mine? People who are really optimistic about it will only make a lot of money in silence, and even go around saying that Bitcoin is not good, so as to prevent others from snatching it from them. The only advantage of deceiving people into the industry is to deceive people into taking over the business. The speculators you mentioned do not doubt that Bitcoin is a bubble, but they know better that as long as they deceive fools into cashing out before the collapse, they can still make a fortune regardless of whether it is a bubble or not. It’s such a simple truth.
The above is the latest disappearing video of players in 2020
The so-called listening and understanding
In fact, what this thing has fallen into now is almost the same as most financial speculation. In the long run , short-term, bankers, and retail investors are all the same routine.
㈦ What is CNS certification?
CNS is China National Standards Certification and is the abbreviation of China National Standards.
Chinese national standards are national standard codes including language coding systems, which can be represented by member organizations of the People's Republic of China in the International Organization for Standardization (ISO) and the International Electrotechnical Commission (or International Electrotechnical Commission, IEC) Published by the National Standardization Administration Committee.
The mandatory standard is named "GB". The recommended standard is titled "GB/T". Standards released in 1994 and before use 2 digits to represent the year. For standards released starting in 1995, the year after the standard number was changed to be represented by 4 digits.
(7) Extended reading of Orchid Grass Blockchain ProtocolTo query standards, you can go to the National Standard Document Sharing Service Platform
"Construction of Standard Document Sharing Service Network" It is one of the key construction projects of the National Science and Technology Basic Conditions Platform. It is led by the General Administration of Quality Supervision, Inspection and Quarantine and undertaken by the China Institute of Standardization. The implementation period is three years. During the three-year project implementation process, the principle of "building while serving" has always been adhered to;
After completing various tasks specified in the project mission statement,At the same time as the task, the transformation from "project" to "platform" was realized, and finally the "National Standard Document Sharing Service Platform" (hereinafter referred to as "Standard Document Platform") was built for nationwide operation services, which to a large extent solved the problem of Problems such as difficulty in obtaining standard information and duplication of standard resources construction highlight the important supporting role of the "standards literature platform" in my country's social and economic development.
㈧ Ethereum Probabilistic Micropayment
This article is sponsored by the Bihu Community (bihu.com) content support program.
So far, most Ethereum projects require the use of payment channels. Payment channels allow any number of transactions to be sent offline, while requiring only two on-chain transactions:
In between, we can send as many off-chain transactions as needed. This is a big improvement over normal online transactions, as services like video streaming and energy markets allow for continuous payments of small amounts.
Since two on-chain transactions are required, we cannot simply give a penny to someone we don’t have a channel for yet, because the transaction fees for channel initialization and settlement will be many times greater than the payment.
How can we send arbitrarily small amounts to any number of recipients without needing to initialize or settle the transaction?
Answer: Ethereum probabilistic micropayments can send any number of payments to any number of recipients without requiring the recipient to initialize or settle the transaction.
Sounds too good to be true, right? That's pretty much it - we always need at least one on-chain transaction to resolve a payment, but payments can be effectively received without any on-chain transaction taking place.
Pay attention to the qualifications of each payee based on the distinction above; a subtle but important distinction. Ethereum probabilistic micropayments only require each sender to make an initial transaction, lock a certain number of tokens, and then send the tokens to any recipient. The payee does not need to establish a payment channel with the sender. Let's see how it works through an example.
At Orchid Labs, we are working on a new decentralized network with the goal of eliminating surveillance and censorship from the Internet. In the Orchid network, bandwidth contributors (called nodes) share their bandwidth and relay traffic for users connected to the Internet. Users continuously pay tokens to bandwidth contributors (automated by user clients).
One node of Orchid can serve thousands of other nodes, and users can also use hundreds of nodes to access different websites and establish transaction fees for state channels between nodes (even if a state channel such as Raiden Network is used ) is too high.
Therefore, we adopt Ethereum’s probabilistic micropayments
This scheme is described in detail (partly formal) in the Orchid Draft white paper, which discusses and refers to the previous work on probabilistic micropayments. research and itsApplicability to blockchain.
While we cannot use this scheme for a single payment, since the recipient is not guaranteed to actually receive the payment, we can use it to cryptographically prove to the recipient that they received the note with some probability , resulting in a claimable payment.
Since we can configure the exact win probability, win amount and frequency of note usage, we can reduce the difference (trade balance) to a negligible degree.
In other words, as long as the service provided is continuous and granular enough that the probabilistic variance becomes negligible, probabilistic payments are more efficient than payment channels.
Let’s imagine a decentralized YouTube where anyone can stream videos to any audience.
Even if the note does not win, there is still cryptographic proof that you are paying because neither the sender nor the recipient can manipulate the value that determines whether the note won. With this proof in hand, you're happy to continue streaming your videos to your viewers. Since thousands of (new) viewers connect to you, there is no overhead per viewer - the only overhead is when you want to publish your winning tickets on-chain.
For a given "average total payment", the likelihood of winning (and therefore the frequency of tickets) determines the number of on-chain transactions required. Therefore, the higher the win amount is set, the less transaction fees the recipient will pay over time. The lower the win amount is set, the fewer tokens locked by the sender and the lower the liquidity cost.
For video streaming, a reasonable profit amount might be $2.78. For power or energy markets, it might be $27.
A key part of probabilistic payments is ensuring that double spending is not possible, otherwise, there is no guarantee that the sender is not cheating. The aforementioned "penalty escrow" double-spends our scheme to the detriment of the sender. How this works is that the sender must lock (a locking contract on the blockchain) a certain number of ticket win amount tokens before the ticket can be constructed. The recipient verifies that the sender not only has sufficient funds to pay the winning ticket, but also that there is a sufficient balance in their penalty escrow.
In the case of a double spend, the on-chain payment contract for the winning ticket will result in a deduction from the sender's penalty escrow account in the event that the sender's balance is insufficient to pay the ticket. This effectively burns the small deposit a sender is required to send, causing a financial loss to the sender and thereby disincentivizing double spending. The penalty escrow amount should be set high enough to prevent double spending, and even low enough to cause little inconvenience to the sender.
Ethereum probabilistic micropayments have several advantages over payment channels for systems that provide continuous fine-grained services to users. The reduction in transaction fees enables not only efficient micropayments, but also nanopayments.
Video streaming, power/energy markets and bandwidth sharing are good examples of applicable systems. we onlyRequires one on-chain transaction per receiver, rather than incurring initial transaction costs per sender/recipient pair, or using a complex payment channel network. Service providers are able to start serving users immediately without running the risk of being cheapskated. Users can quickly disconnect if they stop receiving service.
This allows the service to completely avoid the cost of freeloaders and prevent denial of service attacks immediately, since we can even require an additional micropayment on the first request.
"It is worth mentioning that during our research we realized that this concept actually dates back to 1996 in the literature (see our white paper References), where David Salamon independently derived the probabilistic micro Payment."
Translator's thoughts: Bitcoin's Lightning Network and Ethereum's Raiden Network are both based on state channels and require two transactions, both of which are contract executions and require a large amount of handling fees. And iota's Lightning Network (IOTA itself is not a blockchain, and transactions do not require handling fees, but it can prevent double-spend uncertainty). Orchid Network’s probabilistic micropayments solve these pain points.
