BTC results

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

The impact of the okex incident on the currency market is fading; With the US election becoming increasingly white hot, the difficulty and hash rate of bitcoin are higher than before

in terms of price, so far, BTC has rushed to around us $11720, with a 24-hour increase of more than 2%

so the question is: where will bitcoin go in the next week

here are five factors that may affect the BTC price trend in the coming week

No.1 US macro level: election and stimulus plan this week, the US is the absolute focus of the macro market. The US presidential election will soon usher in a decisive moment (November 3)

analysts warn that if the Democratic Party (Biden) wins, the dollar will depreciate - and the long-term outlook for the dollar is already precarious. Goldman Sachs said last week that Trump's re-election was not enough to get the dollar out of danger

however, no matter what the election result is, professionals recommend buying gold as a hedge. However, in the view of others, bitcoin may bring more profits

However, e to the inverse correlation between BTC / USD and the dollar currency index (DXY), the strength of the US dollar, in the view of some bitcoin traders, will still affect the price trend of bitcoin. Although this correlation has become less and less obvious in recent weeks, the sudden weakness of the US dollar is still likely to be a boon for bitcoin

at the same time, not only the election, but also what happened before is also a topic of interest. Specifically, a coronavirus stimulus plan was in place before polling day

If this happens, trillions of dollars of liquidity will increase the growing debt pile of the United States, and Americans will see additional benefits, such as an additional $1200 economic stimulus plan

No.2 Europe suggests more intervention

with the outbreak again, the European Central Bank (ECB) is considering further measures

European Central Bank President Christina; In an interview with Le Monde on Monday, Lagarde said the European Central Bank would use more financial instruments if necessary

the European Central Bank's coronavirus stimulus program has purchased a total of 1.5 trillion euros of assets

"We haven't run out of options in our toolbox yet," says Lagarde

brexit is increasingly moving towards "no agreement" brexit, which makes the possibility of instability worse

No.3 the fundamentals of bitcoin have reached a new high

recently, bitcoin has maintained a strong resilience in the face of various black swan events. Influenced by okex, BTC recently dropped below $11200, but recovered steadily soon. So far, it has exceeded $11600

and on the technical level, the fundamentals of bitcoin also maintained a record strength this month

two days ago, the difficulty of the latest adjustment increased by 3.5% than expected

at the same time, the hash rate also climbed to a record high on Monday. At the time of publication, the estimated computing power for mining is 146 exahashs (EH / s) per second

as often reported in the media, the popular theory is that the price follows the hash rate, because the long-term investment prospect of bitcoin is better than ever before

No.4 analysts focus on $12000 BTC price breakthrough

for famous analyst Micha & # 235; For Lvan de Poppe, the key price conversion of bitcoin is becoming more and more reasonable

in his latest video update on Sunday, he stressed that the significant resistance level of weekly closing price below US $12000 for several consecutive years will soon end

Van de Popper believes that since the beginning of the bear market in early 2018, US $12000 has become the rejection point of the weekly chart, but the consolidation below cannot last forever

he concluded: "we are likely to rebound to the range of US $16000 to US $17000, because this is the obvious level and the last obstacle for bitcoin to begin to break through the all-time high."

after this move, there will be another consolidation period, which may last longer than the current period

van der BOPP added that he advised viewers to work hard to accumulate bitcoin, even in the $16000 range

No.5 market sentiment: greed is back

with the graal strengthening of prices, investor sentiment is also changing: data shows that investor sentiment is becoming more and more greedy. In the latest market data, the fear and greed index has returned to the "greedy" area, rising slightly from "neutral" in the past week

this indicates that bitcoin investors' emotional expectations will be bullish, but it should be noted that if the price rises too fast, "greed" will become "extreme greed", in which case the index is more likely to callback

5. Even if usdt is a digital dollar, this bitcoin can be converted into dollars at any time. It's just a handling charge.

6. In fact, human beings are a complex biological science research carried out by aliens secretly. The development results seem to develop naturally. In fact, every step is the result of data regulation by aliens, and the whole process has been secretly transmitted back to the alien base. Refinement to each person's growth and development may correspond to a program variable in the operation process, or a non unique answer to a problem. For example: Americans and Asians, in fact, correspond to the X and Y in the alien project research. Taking different values will get different effects.

7. For bitcoin, don't invest any more. It's a complete gamble. Remember, don't participate, especially at this stage. The threshold itself is very low. Bitcoin is not money. It can be divided into any large unit, such as 0.0000015 bitcoin. I don't know when the concept of bitcoin was changed into bitcoin. It can be worthless at any time

8. There are a lot of them, such as fire coin, coin safety, coin station and so on. Mainly depends on the license plate of the exchange, which is a powerful representative of the strength.

9. Wen Yuan & Chen 8658; Hanze! These people were first introced by their aunt or sister, and then they were brought into the group to talk about the stock for free. They introced the buying and selling points, so that everyone could buy and sell along with them, and then they could exchange the short position of quilts for others. They provided a fast way to make money. They provided a virtual trading platform to transfer money into US dollars to buy mythical currency or bitcoin! I'll follow Ye Tan, a famous person, and apply for 20% of the share. But after we put in the money and converted it into US dollars to buy it, in less than a month, we found an excuse to accompany our family to go abroad for training and assist them to go to the funeral! The group disbanded, also said that fate will get together again this kind of deception! Cheated us out of all our savings! Software also can't log in, also changed the lecture website, and cheated a batch of people! I don't believe it, the police can't accept you! Then our dignified police are just, intelligent and brave. Skynet is grey and careless! Just cast a net to salvage you! Even if I still can't accept you, it's not that I don't accept you. At the end of the time, the day will watch and accept you, and let you split up five cars. It's hard to die
friends, if you are cheated, call the police immediately!

10. Wen Yuan is a liar! Before Wen Yuan, the character was Han Ze, all pseudonyms! Before they cheated us to buy mythical currency, now the dog cheated us to buy bitcoin on their own fake platform. The data on the platform will be delayed compared with the external disk. In this way, they can control long or short. If they ask you to reverse it, you will be closed, and you will not know how to die! These are all pig plates (three months of harvesting victims, the first month has given lectures for Mingbo's favor, the second month deliberately said that stocks are not easy to do, how good digital currency bitcoin is, and then told you that their own fake digital currency has prospects, deliberately took out their own fake account to cheat people in, the third month after harvesting, the swindler lost contact, and the swindler retreated completely), We have been cheated in the case of 10 people arrested, but this fake article is far from continuing to be a shooter, cheating! Now, there is a group called "competing for the best" and an organization called "JingWuMen". They have a clear division of labor among cheaters (lecturing, entrusting, collecting money, opening an account, assistant, etc.) and really ignore the national law! Now Wenyuan has an account holder named Liu Qian, Zhang Jia (pseudonym) and others. I suggest you buy ukgr digital currency! Lower case (ukgr) don't buy it. The platforms are all made by themselves. You can control the rise and fall at any time. If it's not a real platform, you can close the platform at any time! It's the same as the myth coin recommended by Han Ze (the same person in Wenyuan) before. It's all fake! At present, we have lost hundreds of millions! The whole country has also set up an ad hoc group to solve this case. I hope that more people who have been cheated can read this article, so that this group of swindlers can be less successful! Finally! The most important word! Ask the local police before investing, because they will explain to you that this is a fraud! It's a fraud!
