1. If silver is so easy to earn, why can't so many people find jobs to support themselves? Why are so many people struggling to make ends meet with the minimum wage? Can't they all surf the Internet and ask questions? Are they all people who don't want to succeed, who don't see the trend of the times, and who don't want to make progress? There are just a few types of deceptive routines. You should take the right seat first. 1. Claim to recruit, and then let you pay in various names -- deposit, deposit, filing fee, integrity fee, clothing fee, physical examination fee, training fee. Whether it's on the Internet, on TV or in the newspaper, you should have heard about the tactics of those black intermediaries. Do you have to cry and cry to pay those people? 2. Claim to be a task, let you send spam ads everywhere, recruit people, pull people to be cheated. Now you can see why there are so many job advertisements and those who are entrusted. How much does a person pay? Why don't you pay for such a good thing? 3. Claim to type, let you pay the express fee and postage first, and then the other party will add your blacklist and give you the lost game. When you think of a publishing house in this country, you can open it casually. Can anyone pretend to be a publishing house or a fictional publishing house so that you can be fooled? For example, those advertisements that pretend to be publishing houses or fictitious publishing houses, the questioner and the respondent sing one song and advocate that so and so publishing houses are true and reliable, without exception, they want you to believe that they are true and pay money. 4. Claim to post, let your mobile phone register, input verification code, personal signature, secretly customize high price information service, dect your call fee until it stops. For example, those who want you to enter the mobile phone number, or try to cheat your mobile phone number, you should be careful of such places. Don't post your identity information and mobile phone number everywhere, for fear that it won't fall into the hands of insurance, intermediary, fraud and communication gangs. 5, claim to make money, give you a suspicious link, let you contribute to the click through rate and popularity. It's worthwhile to spend so much energy on these advertisements, pay for Internet and electricity, and spend your eyesight, energy and time. 6. Claim to verify, ask you to provide a bank card, cheat you to enter the password, and seize the opportunity to steal the balance. The security of personal information cannot be overemphasized. Be careful. It has been reported many times on TV and on the Internet, but someone still wants to write. Maybe we should let them be cheated several times, which is a kind of ecation. 7. Claim to start a business, ask you to pull people's hair exhibition offline, claim to invest how much, return how much. Have you seen the episode of Caimen? If you buy three knives, you will be the black iron brothers; if you buy 30 knives, you will be the bronze brothers; if you buy 300 knives, you will be the silver brothers; if you buy 3000 knives, you will be the gold brothers; if you still have the diamond brothers, the value of the goods you buy will deviate from the value of the goods you use. No matter how they claim to be or how they flaunt them, they are all traditional cutting. Those who peddle online shop advertising, advertising everywhere, waiting for you to come from the investment network. Every day I look forward to your listening to their eloquence and bringing them rich benefits. And we, who hate advertising, what do you want? If you can't tell the good from the bad, or conspire with them to sell advertisements, you don't have to say much. 8. Claiming to be a part-time job, sending you poisonous content, infecting your chat tools, and sending profitable advertisements to your friends. A few days ago, a friend met him: he pretended to be a good friend by using chat tools, claiming that he had a car accident and asked him to remit money to save his life. Fortunately, he found out in time that it was a fraud.
2. A few days ago, Ogawa burst out a bunch of comments under an article entitled "today's most popular blockchain technology is no doubt. Let's not talk about it, are we out?" but Ogawa was very happy. It's rare for an article to attract so many comments. Happy Ogawa can't wait to click and have a look. The result is also shocked. What's the ghost of the next big wave of captcha? What do you think of it
3. Before the establishment of

4. You can use the method of forced restoring factory settings to clear the password without brushing the phone, but it will also clear all data in the phone: turn off the phone, press and hold the tone key up and power key at the same time until the logo interface is displayed, and select restore factory settings
if the mobile phone is upgraded to the emui5.0 platform, if the search for my mobile phone is enabled, you need to enter the correct Huawei account and password. Most Huawei accounts are commonly used email or mobile phone numbers. It is recommended to try them separately. If you forget your password, you can log in to cloud.huawei.com on the computer, and click forget your password on the login interface to verify through your mobile phone number or email number, Follow the prompts to reset the password. If the account is disabled and cannot receive the verification code, or it has not been bound with a secure mobile phone or secure email, you can only make an account complaint.
5. There are few reliable loans for this small loan company, that is, the so-called loan without qualification, and the high interest rate is scary. There is no need to contact this. You can consider the following bank loans or Alipay Jingdong.
6. Take advantage of the loophole. If the code is not well written and the abnormal data is input, it will jump to the set address and execute the set code

above, if you are satisfied, please take it< br />
8. Proof of work (POW) is a proof to confirm that you have done a certain amount of work. The whole process of monitoring work is usually extremely inefficient, and it is a very efficient way to prove that the corresponding workload has been completed through the certification of the work results. For example, in real life, graation certificate, driver's license and so on, are also obtained through the way of test results (through the relevant examination)
proof of equity mechanism
POW is a way to reach a consensus, but it is not the only way. There are other ways for each node to reach a consensus, such as POS
POS is different from POW in that
mining on POS system is based on the amount of money held. In other words, in the case of POS, the effect of a person owning 5% of the
virtual currency is the same as that of a person owning 5% of the
computing power on
bitcoin system
the basic principle of workload proof the main feature of workload proof system is that the client needs to do some difficult work to get a result, but the verifier can easily check whether the client has done the corresponding work through the result. A key feature of this scheme is asymmetry: the work is moderate for the requester and easy for the verifier. Different from captcha, captcha is designed to be easily solved by human but not by computer. The following figure shows the process of workload proof:
for example, given a basic string & quot; Hello, world!& quot;, Our workload requirement is that an integer value called nonce can be added after the string to perform sha256 hash operation on the changed (nonce added) string. If the hash result (expressed in hexadecimal) is & quot; 0000" At the beginning, the verification is passed. In order to achieve this goal. We need to continuously increase the nonce value to perform sha256 hash operation on the new string. According to this rule, we need to go through 4251 calculations to find the hash with exactly the first four bits of 0
. In the process of workload proof, we can roughly summarize the steps of bitcoin miners to solve this puzzle of workload proof as follows: generate coinbase transaction, and form a transaction list with all other transactions that are ready to be packaged into blocks, generate Merkle root hash through Merkle tree algorithm, and assemble Merkle root hash and other related fields into blocks, The 80 byte block header of the block header is used as the input of workload proof, and the random number in the block header, that is, the value of nonce, is constantly changed, and the block header after each change is double sha256 operation (that is sha256 (sha256 (block)_ If it is less than the target value, the problem is solved successfully and the workload is proved to be completed. The process can be shown in the following figure:
the workload proof of bitcoin is the main work we commonly call "mining". Understanding the workload proof mechanism will lay a foundation for us to further understand the consensus mechanism of bitcoin blockchain.
9. The most pitfalls! When other apps pay for their membership cards, they will definitely get rid of them. This app is funny. If you want the black diamond card for 4999 and the membership fee for 99149, you will be rejected. It's funny to claim 10 cents. Originally, it's necessary to borrow money and cheat people who are short of money in disguise. Is it human?
