50btc

3. In order to understand the technical principle of bitcoin, we need to understand two important cryptographic techniques: hash code: it converts a long string into a fixed length string, and its conversion is irreversible, that is, it is impossible to guess the original string from hash code. Sha256 is mainly used in bitcoin protocol
public key system: corresponds to a public key and a private key, keeps the private key in the application and publishes the public key. When Party A transmits information to Party B, it can use Party A's private key to encrypt the information, and Party B can use Party A's public key to decrypt the information, so as to ensure that the third party cannot impersonate Party A to send the information; At the same time, when Party A transmits information to Party B, it is encrypted with Party B's public key and sent to Party B, and then Party B decrypts it with his own private key, so as to ensure that the third party cannot eavesdrop on the communication between the two people. RSA is the most common public key system, but the lliptic curve digital signature algorithm is used in bitcoin protocol. What's the difference between cash and bank account? Bitcoin is an electronic currency in BTC. In this article, it is also used to refer to the whole bitcoin system. Like opening an account in a bank, the corresponding concept in bitcoin is address. Everyone can have one or more bitcoin addresses, which are used to pay and collect money. Each address is a string that starts with 1. For example, I have two bitcoin accounts, and. A bitcoin account is uniquely determined by a pair of public key and private key. To save the account, you only need to save the private key file. Unlike bank accounts, banks keep all transaction records and maintain the book balance of each account, while bitcoin's transaction records are jointly maintained by the whole P2P network through a pre agreed protocol. How much money is in my account address? Although the current account balance can be seen by bitcoin software, unlike banks, there is no place to maintain the book balance of each address. It can only calculate the account balance in real time through all historical transactions. How do I pay? When I pay from address a to address B of the other party, the payment amount is e. at this time, both parties will announce the transaction information to each network node, telling address a to pay to address B, and the payment amount is e. In order to prevent the third party from forging the transaction information, the transaction information will be encrypted with the private key of address A. at this time, the network node receiving the transaction information can use the public key of address a to verify that the transaction information is indeed sent by address a. Of course, trading software will help us do these things, we just need to input the relevant parameters in the software. What will the network node do after receiving the transaction information? This is the most important part of the bitcoin system, which needs to be elaborated. For the sake of simplicity, only bitcoin protocol has been implemented. In the current version, each network node will save all transaction information synchronously. There are two kinds of transaction information in history, one is & quot; Verified & quot; The transaction information, that is, the verified transaction information, is stored in a series of "blocks". Each & quot; block" Is the previous & quot; bock" The ID of each block is the hash code of the hash code of the block and the new transaction information (see an actual block). The other category refers to those who also & quot; Unverified & quot; The transaction information just paid above belongs to this category. When a network node receives new unverified transaction information (possibly more than one), it can calculate the book balance of each address at that time because the node keeps all the transaction information in history, so it can calculate whether the transaction information is valid, that is, whether there is enough balance in the payment account. After eliminating the invalid transaction information, it first takes out the last & quot; block" Then, the unverified transaction information is combined with the ID, and a verification code is added to form a new "block". It needs a lot of calculation to build a new block, because it needs to calculate the verification code, so that the above combination becomes a block, that is, the first several bits of the hash code of the block are 1. At present, the first 13 bits need to be 1 (generally, the specific method is uncertain), which means that if the block is generated by enumeration method, the average number of enumerations is 16 ^ 13. Using CPU resources to generate a block is called "gold mining", because the proction of the block will get a certain reward, and the reward information has been included in the block. When a network node generates a new block, it will broadcast to other network nodes. However, this network block may not be accepted by the network, because it is possible that other network nodes have proced the block earlier. Only the earliest block or the block with the largest number of subsequent blocks is valid, and the remaining blocks are no longer used as the initial blocks of the next block. How does the other party confirm that the payment is successful? When the payment information is distributed to the network node, the network node begins to calculate whether the transaction is valid (that is, whether the account balance is enough to pay), and attempts to generate blocks containing the transaction information. When six blocks (one direct block and five subsequent blocks) contain the transaction information, the transaction information is considered "verified", so that the transaction is formally confirmed, and the other party can confirm the successful payment. A possible problem is that I will pay the balance of address a to address B, and at the same time pay to address C. If I only verify that the single comparison transaction is valid. At this point, my way of cheating is to generate six blocks including B to B and six blocks including C to C before the truth is revealed. Because I need a very long CPU time to generate a block, compared with the whole network, the probability of my cheating success is very small. What is the motivation of network nodes to proce blocks? As can be seen from the above description, in order to make the transaction information effective, the network node needs to generate 1 and 5 subsequent blocks to contain the transaction information, and such block generation is very CPU intensive. How to let other network nodes help to proce blocks as soon as possible? The answer is very simple. The agreement stipulates that BTC will be rewarded for the address where the block is proced, as well as the Commission promised by both parties. At present, the reward for procing a block is 50btc, which will be halved every four years in the future. For example, the reward will be 25btc from 2013 to 2016. Is the transaction anonymous? Yes, and No. All bitcoin transactions are visible. We can check all transaction records of each account, such as mine. But what's different from the banking monetary system is that everyone's account itself is anonymous, and everyone can open many accounts. In general, anonymity is not as good as it claims. But bitcoin has another advantage in doing black market trading: it can't be frozen. Even if the police trace a bitcoin address, there is nothing they can do unless they trace the computer used by the exchange based on the Internet address. How to ensure that bitcoin does not depreciate? Generally speaking, in the case of equivalent trading activities, the value of money is inversely proportional to the amount of money issued. Unlike the traditional money market, the central bank can determine the amount of money issued. Bitcoin does not have a central issuing institution. Only by procing blocks can we get a certain amount of BTC currency. Therefore, bitcoin's new amount of money depends on: 1. The speed of procing blocks: bitcoin's agreement stipulates that the difficulty of procing blocks is fixed at an average of 2016 every two weeks, about 10 minutes. Moore's law of doubling CPU speed every 18 months will not speed up the proction of block. 2. The number of rewards for block proction: at present, 50 BTC is awarded for each block proced, which is halved every four years. In 2013, 25 BTC is awarded, and in 2017, 12.5 BTC is awarded. Considering the above two factors, bitcoin's currency issuing speed is not controlled by any single node in the network. Its protocol makes the currency stock known in advance, and the maximum stock is only 21 million BTC

First, "private transactions" (private transactions between the withdrawer and others (people who need bitcoin) can realize their own bitcoin

Second, the withdrawer is a registered user of a bitcoin wallet. The registered user can operate in the background of bitcoin, and the wallet platform provides security guarantee. The coin bag is of a similar nature

thirdly, registered users can enter the background of the trading platform to carry out cash withdrawal operation, and the security guarantee of cash withdrawal is provided by the platform itself

Fourth, the withdrawal of bitcoin itself is converted into RMB. After the registration of the registration trading platform (bitcoin China), there will be an IP address, and then you can send your own bitcoin to this website

Fifthly, after completing the above operation (wait for 10 minutes, or shorter), bitcoin will be displayed on your account, and then you can sell it at the platform price, so that you can exchange it into RMB

5. In payouts, it's very obvious that LZ needs to drink more foreign ink....

6. BTC and usdt prices of OTC platforms are based on the average prices of bitfinex, bitstamp & coinbase, which will be updated every minute.

Ma Yun, male, Han nationality, CPC member, was born in Hangzhou City, Zhejiang Province on September 10, 1964. His ancestral home is Gulai Town, Shengzhou City, Zhejiang Province. He is the main founder of Alibaba group. He is now a director of Softbank of Japan, chairman of the Chinese Council of the Nature Conservation Association and a member of the global board of directors, director of Huayi Brothers, director of the life science breakthrough Award Foundation, and director of the National Science Foundation Co chair of the United Nations High Level Panel on digital cooperation

In 1988, he graated from the Foreign Language Department of Hangzhou Normal University. In the same year, he was a teacher of English and international trade in Hangzhou Institute of electronic technology. In 1995, he founded China yellow page, the first Internet business information publishing website in China. In 1998, he became the general manager of guofutong Information Technology Development Co., Ltd., China's international e-commerce center. In 1999, he founded Alibaba, and served as the CEO of Alibaba group Chairman of the board

on May 10, 2013, he resigned as CEO of Alibaba group and continued to serve as chairman of the board of directors of Alibaba group. On June 30, Ma Yun was elected as co chairman of the Council of the global Internet governance alliance. On September 10, 2019, Jack Ma stepped down as chairman of Alibaba's board of directors and continued to be a member of Alibaba Group's board of directors

extended materials:

in March 1995, Ma Yun resigned from Hangzhou Institute of electronic technology, took out 6000 or 7000 yuan, borrowed more than 10000 yuan from his sister and brother-in-law, and raised 20000 yuan to start a business

In April 1995, Hangzhou Haibo Computer Service Co., Ltd., the first Internet business company in China, was established. The three employees are ma Yun, his wife Zhang Ying and he Yibing

in May 1995, China yellow page was officially launched, and Ma Yun began to do business from his friends. At this time, China is still three months away from being able to access the Internet

In July 1995, China yellow pages created a website for Zhejiang Provincial Foreign Publicity Office to publicize Zhejiang's economy and culture, which is called "Golden Pigeon project"

In March 1996, Ma Yun decided to merge with Hangzhou Telecom because Hangzhou Telecom also established a Chinese yellow page and food sharing market. China's yellow pages are priced at 600000 yuan, accounting for 30% of the shares, while Hangzhou Telecom has invested 1.4 million yuan in cash, accounting for 70% of the shares

In 1997, after being invited by the Ministry of foreign trade and economic cooperation to set up China international e-commerce center (EDI) in Beijing, Ma Yun decided to give up China yellow pages. He sold 21% of his Chinese yellow pages to the company at a price of 20-30 cents per share and got back more than 100000 yuan. After that, Ma Yun and his team developed a series of websites in Beijing, including the official website of the Ministry of foreign trade and economic cooperation, online china commodity exchange market, Online China Technology Export Fair, China Merchants, online Canton Fair and China foreign trade and economic cooperation

1, tiktok

, and the demand for the powder in the contents of the jitter, such as: the biggest distance between the world is not China and the United States, but we can hardly meet, but you brush past, and die no longer. I have so many wonderful things to tell you, pay attention to me

2, release the high quality video

shaking sound number, and then we must seriously distribute it and send out high-quality video. Tiktok tiktok, like many of your classmates playing like a social account, today sends their own cat and will take a meal tomorrow. The jitter is a platform for weighing the weight. This subsystem will give you the right to drop your weight, affect your video recommendation, and you will not know who you should recommend to your video system. p>

so from the beginning, you have to work hard to find topics, write writing, and shoot. Every one of them is of high quality. Only in this way can they become popular quickly

. Then you can choose your interesting tiktok based on the title of the subtitle, click it, that is the details of playing the jitter.

3. Improve the interaction rate

the so-called interaction rate mainly refers to how high the user's comment intention is, rather than your response rate after the user comments. There are two ways to improve the interaction rate

a p>

we usually embed about three comments in the message area, which can be questions about the topic, or jokes about the topic, or very sharp questions. In short, we should attract users to stay and have a look, attract users to pay attention to the comment area, or even directly participate in the topic discussion. This has two advantages: first, the interaction rate is improved; second, the completion rate and the length of stay are also improved

B. warm up and ask questions in the title of the short video. For example, the previous topic was to discuss the relationship between payday and company niucha. The video thinks that most good companies pay their salaries before the 15th. In the title of the video, we guide users to leave messages about their payday and whether they agree with our summary. Message area is very hot, driving the overall video data

4, batch draining

can send gifts to the voice signature, or tiktok. For example, make-up can be said to receive a free make-up skills secret book, or seven days to learn PS, pro test effective. The purpose is to direct the users who pay attention to your videos to wechat< P>5, tiktok tiktok challenge

's essence is that many users create around the same topic, and challenge the vibrato voice will be released every day, basically in the noon and evening each, a few time will release a number of challenges. p>

it is very important to participate in the challenge activities, participate in the first time, and the content visibility. If you rush to publish in the front position, you will get a number of different natural traffic e to the first mover advantage, and the content visibility will affect whether the subsequent recommendation traffic will continue to come
