How to understand the blockchain consensus mechanism
Publish: 2021-04-25 22:35:45
1. There are many consensus mechanisms in the blockchain. The advantage of the pow consensus mechanism behind bitcoin, the most influential one, is that it is secure and can not be tampered with. The disadvantage is that it is too slow to process only seven transactions a second
2. It is also a concept in blockchain, which refers to the algorithm for blockchain things to reach distributed consensus. They speak very clearly on the app of lianpai community and have a thorough understanding of blockchain. Although their one course is not long, they can understand it after listening to it. Very good!
3. The analysis of Chongqing jinwowo network is as follows:
blockchain is a decentralized distributed ledger system. Due to the high network delay in the peer-to-peer network, the transaction order observed by each node can not be completely consistent
therefore, the blockchain system needs to design a mechanism to reach a consensus on the sequence of transactions that occur in the same time
this algorithm to reach consensus on the order of transactions in a time window is called "consensus mechanism".

4. Sludge specific resistance is a comprehensive index of sludge filtration characteristics. Its physical meaning is: the resistance of unit mass of sludge in unit filtration area when it is filtered under a certain pressure. The purpose of this value is to compare the filtration performance of different sludge (or the same sludge with different amount of mixture). The larger the sludge specific resistance is, the worse the filtration performance is. The curve showing the relationship between the gas flow rate treated by the adsorption bed and the pollutant concentration in the outlet gas is called breakthrough curve. For details of this concept, please refer to line 9 from the bottom on page 278 of air pollution control engineering, Second Edition, published by higher ecation press~
5. Jinwowo network analysis: consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering.
6. The reasons are as follows: 1. The United States does not allow the suspect to be punished personally, that is to say, if the person does not speak, there is no way! American suspects have the right to silence. Therefore, no one can help him if he doesn't speak. 2. In the United States, there is always a law of egg pain, which can be used to account for the whereabouts of the victims and demand a light sentence! That's why the suspect didn't speak. I didn't hurt anyone, no body! So this can be a lighter sentence. 3. What's more painful is that there is no death penalty in the state where Zhang Yingying went. The reason why the case is not closed is that there are no bodies! According to the law of the United States, it may be the one who got off the bus half way and lost himself!! Because there's no body! Therefore, only Chinese law is just!
7. Jinwowo uses a vivid metaphor to illustrate: if consensus is the basis of blockchain, then consensus mechanism is the soul of blockchain
when explaining what a blockchain is, we can use a simple and clear decentralized distributed ledger to summarize it. However, in this ledger, how to sort the things generated in almost the same time is related to the consensus mechanism of the blockchain network
therefore, jinwowo network technology believes that consensus mechanism is an algorithm to reach consensus on the sequence of things in a period of time.

8. Step 1: Title
let's not talk about the content, let's talk about the title first. The first thing we show you is the title. If our title can't catch the eyes of users in a moment, it may lose users to continue to read. No matter how good your content is, it's useless
therefore, when we do proct writing, we must have a very attractive title, and we often use two kinds of title writing methods:
the first type: threatening type. When people feel panicked, they run away. If you see these headlines, what's your reaction“ Baijiu + beer + Red Wine = poison! " Drinking homemade wine is equivalent to chronic suicide The second type: benefit type. When people feel happy, they want to have it. What's your reaction to this title“ Hand made crystal cup free! It's also postal! Come and grab it
Step 2: make good use of curiosity
"Curiosity Kills the cat". I believe everyone has heard of it. Curiosity is human nature, but laziness is also human nature. If you want your users to read your articles carefully, you must arouse their curiosity. Before the text begins, you need to enlarge the content of their curiosity. Only in this way can you be enthusiastic about your long articles
if users open your page and close it after reading a paragraph, you will not have any marketing opportunities. Therefore, in this place, we must guide users. You need to let them continue to be interested. In the front, there is no need to promote any procts. Retaining users first is the key. If users stay, there are plenty of opportunities for marketing. For example, the following headlines can arouse people's curiosity: "don't eat these dishes when drinking wine", "why do people buy 9.9 yuan imported red wine?"
Step 3: customer feedback
as long as the user is interested in you and likes to read your "first paragraph" carefully, he will naturally read your "second paragraph"
but we should remember that there is no relationship between us and users in this place. What should we do if users do not trust us? Trust marketing is the best marketing method, so we must let users have a certain trust in us before marketing. How to make a stranger trust you immediately? The best way is the feedback from other people, that is, the third party's evaluation of you, especially the evaluation and feedback from his friends. The user needs a sense of security, worries that his judgment is wrong, and he needs reference and suggestions. If you know this, you can solve his inner uneasiness in advance, so that he can trust you
Step 4: value packaging
we need to know that what customers buy is the proct value, not the proct itself, so you must intuitively tell the users what your proct value is, clearly tell them what benefits the proct can bring him, what can be used, and how to use it to maximize the value. Even a lot of times, you can tell users the story behind the proct, how the proct was born, why such a proct was launched, how the process of the proct is, how much effort has been put into the user, and so on
for example, the "big golden sheep" of tianezhuang, which was popular in the circle of wechat friends not long ago, has a remarkable value package of "1.5-liter package" (subtext is suitable for gifts to relatives and friends). It adopts the screen printing process, and uses professional glass ink to print patterns to wine bottles, instead of traditional paper labels in the past; Step 5: content introction
content introction is a comprehensive introction of the proct, multi angle introction, so that customers can fully understand the benefits and characteristics of the proct, including expert comments, supporting documents, delivery, price, payment and other information. You need to decompose the proct into various interest points, and then describe it in the customer's usual language. The most important thing is to "describe the result". Each paragraph is a result for him. Some boutique wine companies list Robert Parker's rating or the international authoritative wine magazine PinChun guest's rating beside the introction of wine, which is also a small skill that can be used for reference
Step 6: call for action
if the user does not take action, your will be written in vain. At the same time, the simpler, the more specific and the clearer the action you ask the customer to take, the better. You must not let him do a lot of efforts to be able to buy your procts. If you do, you are depriving yourself of the right to deal with clients
you have to give him a reason to act immediately. People are used to procrastinating and hesitating. Many website writers are most likely to be ignored. Call on users to take action, or buy procts, or fill in online forms, or pay by wechat, or make phone calls in clear and proactive words, so as to push customers to complete the next move you set in advance. You can set a countdown date to strengthen the customer's action
Step 7: zero risk commitment
zero risk commitment can eliminate the buyer's risk in any transaction. When you eliminate the buyer's risk, you also eliminate the main obstacles for the buyer to buy. In this strategy, what you have to do is to bear all the risks between you and the buyer. Let them know that if they are not satisfied, you can simply give them a refund or redo the work for free to make them satisfied
if your customers say that your procts are very attractive, but I'm still worried because I've bought many procts before, and the results are unsatisfactory. If this time, as usual, it doesn't match what you introced after receiving it, and I can't be satisfied, what should I do
you can answer like this: if you are not satisfied with the proct after receiving the proct, we are not worthy of your money, and you have the right to ask us for a full refund. We will return all the money you paid to you immediately. And we won't ask you any questions
Step 8: frequently asked questions and answers
although your writing is very detailed, you will also miss some questions that customers are particularly concerned about. You need to think from the perspective of customers. You need to answer the questions in the writing in advance. What kind of questions and questions will customers have? For example: delivery problems, quality problems, return problems, safety problems, use problems and so on, the more carefully you consider, the more assured and satisfied customers will be.
