How to look at bitcoin multi space ratio
Publish: 2021-05-24 02:05:24
1. 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
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.

2. Factors affecting the price of bitcoin 7: government regulation
some people want to see more regulation of bitcoin, because when the government regulates bitcoin, it will claim that bitcoin is legal or illegal. If it's legal, the laws governing bitcoin can help people measure its availability and longevity
on the other hand, some of us are afraid of government regulation, because the overall view of decentralized money is to keep it decentralized so that no one can control it. The government controls the amount of legal tender in circulation in the country. They can make more money, but they can't directly rece the amount in circulation. Wallet address storage bitcoin and wallet may be accidentally deleted, or they may be locked by forgotten password, but only 21 million bitcoin will be cast. This allows the value of bitcoin to increase over time rather than decrease
now imagine the government's announcement that they are only allowed to exploit cryptocurrency, and only their currency is legal in their country. Well, now we are in the same situation as before the invention of cryptocurrency. The government takes all the money, and they can start and stop mining at will. Maybe they'll even change the code to do more money mining when there's not enough money. The only difference is the form of the trading currency. Cryptocurrency regulation can bring a lot of terrible things, and some people are very afraid of the new rules
those who promote the regulation of bitcoin will buy more bitcoin and increase the value of bitcoin, but those who are afraid of government regulation may start panic selling when news such as nydfs bitlicense comes into play. This makes it possible for government regulation to affect the price of bitcoin. The price of bitcoin is stable. You can explain the news in two different ways
factors affecting the price of bitcoin 6: acceptance of bitcoin
no one uses bitcoin as currency, and bitcoin will not be used for any purpose as currency. When people pay with bitcoin, they are increasing their credibility and showing the world that someone wants to pay with bitcoin. Many people in companies like Dell, Newegg, and dish networks have taken the power of bitcoin to inform and allow customers to use it to buy their procts and services. Xapo offers a new credit card that allows you to use bitcoin for stores that accept regular debit cards
although shoppers have no direct impact on prices, they do help spread bitcoin around the world as a viable currency. Therefore, the impact of bitcoin shopping on bitcoin price factors has no short-term impact, but they provide a larger market
factors affecting bitcoin price 5: Mining
the more miners there are, the more secure the network will be as long as no one owns 51% or more of the network. When an entity owns at least 51% of the mining power in the network, 51% of the attacks may occur
for example, a person can buy a mansion with 10000 bitcoin. The real estate agent who sells the buyer's mansion receives the money and transfers the contract to the buyer to complete the transaction. Buyers now have luxury homes, and real estate agents get 10000 bitcoins from sales, right? Well, buyers have 51% of the bitcoin network hash rate, and they want to return their money while keeping the house. The buyer allocates the block chain before the transaction, and uses 51% network hash to compete for the official part of the fork, so that the new branch is longer than the original branch. In doing so, the entire network now treats the new branch as legal and the original branch containing 10000 BTC transactions as illegal. That means the buyer now has his 10, 00 BTC back. This is called a 51% attack
the 51% attack probability that affects the bitcoin price is the potential panic selling
e to several reasons, the impact of general mining, bitcoin price factors declined slightly. Some miners keep their bitcoin as part of their buying and holding strategies, while others cash in legal tender. Miners also have high electricity bills to run their equipment, so they often sell a large profit for legal purposes in order to pay for their electricity bills
factors affecting the price of bitcoin 4: media opinion
the media does play a role in the price of bitcoin
when most people read the news, most people will take action based on the news. For example, if the news says ghash. IO has 51% network hash value; Some people may launch DDoS attacks on ghash. Io. In front of the mountain, China's news trading is quite profitable. GOx crashes. People will sell panic crazily, so everyone who knows the latest news knows that the people's Bank of China will pitch on bitcoin, and then it will become a rumor that they will sell their collection and buy it back when the market starts to rise again
the key factor influencing the price of bitcoin in this news is the articles it provides. People will buy or sell bitcoin according to its content and send it with higher or lower value correspondingly
factors affecting the price of bitcoin 3: large enterprises mp money
bitcoin is not accepted everywhere; Not every employee wants to accept bitcoin's salary, and not every government system will accept bitcoin and other taxes. Before the world catches up, there are still things to pay in fiat money, so companies usually sell most of bitcoin to pay for their business. Just like the so-called "mping", the value of bitcoin will be in a low state. Depending on the company's sales volume and how many companies were selling bitcoin at the time, this could mimic "panic selling" and cause the price of bitcoin to collapse
the decline in the value of bitcoin is the key factor influencing the price of bitcoin for large enterprises that prefer fiat money< As you can see above, the common reason why management factors work in this way is that they buy and sell bitcoin in other currencies. When traders sell bitcoin on the exchange, the price is very low, and the price usually doesn't change, or the change is very small. If the trader is a large holder of bitcoin, that is, a person with a large number of bitcoin about 1000 + BTC, the price of bitcoin will drop significantly e to its large sales. Generally speaking, orders from large number of cash holders will not be filled with a single price, which is the reason for the price decline. Someone may buy a BTC for $600; Another may buy 20 BTC for $598; There may be more transactions of different values in the middle, and then the seller will sell 0.1 BTC to the buyer for $500. What is the new purchase price of bitcoin? Maybe 499 dollars
for all people selling bitcoin in the transaction, the price factor of bitcoin is always a decline in the value of bitcoin
factors affecting the price of bitcoin 1: trading volume and frequency of exchanges
of course, the primary factor affecting the value of bitcoin is how many people are willing to pay for bitcoin. When you place an order at the exchange to buy bitcoin, you can determine the value of bitcoin to you. The more people are willing to buy bitcoin, the greater the chance of increasing the overall value of bitcoin. The seller sells the highest bid first, so whoever is the current highest bidder is the one who decides the value of bitcoin
when someone buys bitcoin on the exchange, the factor that affects the price of bitcoin is that the value of bitcoin always rises
a formula for calculating the stock price
the rise and fall of the stock is calculated by comparing the closing price (or current price) of the trading day with the closing price of the previous trading day
calculation method of rise and fall range: the difference between the closing price (or current price) of the day minus the closing price of the previous trading day and then dividing the closing price of the previous trading day
calculation formula of rise and fall range: Rise and fall range = (current price - yesterday's closing price) / yesterday's closing price * 100% (the calculated value is positive for rise and negative for fall)
at present, the trading rules of Shanghai and Shenzhen stock markets are as follows: generally, the maximum limit of the rise and fall of each trading day is + - 10% for stocks, + - 5% for St stocks, and + - 44% for new stocks on the first day of listing, and the rise and fall of other special regulations are calculated separately

3. Bitcoin (bitcoin: bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan.

Bitcoin market can be seen on many platforms, but the premise of these is that you can see it and find a reliable proct platform
here is an example, such as coinplus exchange
1. First, go to the official website of the Canadian dollar station, and then look at the home page
the key point is that the platform is very intimate, and even the download steps have direct guidance
the above are just personal opinions, which can be referred to and guided
5. Hello! MGK project has only one app, without any white paper, team introction and background introction related to blockchain. Moreover, the app interface is stuck and unsmooth, and there is no technology at all. The content is just related to "pulling the head". It adopts the offline development mode to attract investors, and claims that it only goes up but not down, and goes up unilaterally. It is obviously a pyramid scheme.
6. That is to say, the delivery price of trading digital currency in a certain period of time in the future can be increased by 10 or 20 times of leverage to do long and short, and the leverage of perpetual contract is greater, up to 100 times.

the signal is a line in the movie, and the landlord has no spare food. The real meaning has been very honest in the previous press conference. Originally, he planned to sell 40 billion yuan of assets this year. but later, he thought that the great recession of global economy or the financial crisis might occur, so he sold another 40 billion yuan. Take a look at this move, It's true that our landlords have no surplus food. They are really rich. However, from sun Zhengyi's tearful purchase of US dollar assets, we can see that sun Zhengyi is full of worries about the future direction of the global economy
in any case, in the capital market, in the big economic situation, only with a cash in hand can we really dominate the world. Sun Zhengyi has created an investment myth, but he may not always be an investment myth, so it is this kind of myth , and we really may not believe him, because it is just a hero who creates the situation, if the opportunity comes, Pigs standing on the air outlet can also become investment myths, so there is no need to consider what signals they really convey?
