How many bits in bitcoin

⑴What is the total amount of bitcoins

The total amount is 21 million, and a block is produced about every 10 minutes. The number of bitcoins in each block is 12.5 after two halvings , that is to say, 12.5 bitcoins are produced every 10 minutes.

2 How many bitcoins are there in total?

The total number of bitcoins is 21 million, and the mining will be completed in 2140. The speed has been halved in four years, and currently, Bitcoin has mined a little more than 13 million. Bitcoin was invented and created by a person named Satoshi Nakamoto, who disappeared from the Bitcoin circle after 2010, and no one knows who this person is.

⑷ What is the total amount of bitcoins

The total amount remains unchanged. It is easy to understand that the total amount of bitcoins, 21 million, will not change. The developer has made it public, and has not kept it privately.
But it can be divided downwards, and it is not difficult to understand. I have 1 yuan in my wallet, and I can also say that I have 10 corners, 100 points, 1000 centi Millimeter, 100000 silk, 1000000 flicker, 10000000 micrometer. No matter what unit of measure I use, I will neither get richer nor buy more stuff, nor have any effect on the economy.

⑸ How many segments of Bitcoin are a level

I don’t quite understand what you mean, Bitcoin doesn’t have any segments. Bitcoin is a consensus network that enables an entirely new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network controlled by its users without a central authority or intermediary. From a user’s perspective, Bitcoin is a lot like the cash of the internet. Bitcoin can also be seen as the most prominent three-entry bookkeeping system out there.

I think what you are talking about is that the network knows that Bitcoin hangs up frequently. I know that it is divided into levels. The higher the level, the higher the income and the higher the investment. But I feel that is a scam. This thing has nothing to do with Bitcoin. Their publicity and promotion model is suspected of pyramid schemes. They told me they were mining, using thousands of computers across the country. If you are in the currency mixing circle, you will understand that ordinary computers are basically unable to mine bitcoins now, let alone thousands, even tens of thousands of ordinary computers can hardly mine one bitcoin a year. In addition to wasting electricity bills, there is no profit at all. How can you share the money without profit. Today, thousands of professional mining machines can mine one coin a day, which is not bad. Now the cost of mining is basically higher than the cost, of course, except that the electricity fee is free, and now the more well-known mining farms in the world have stopped mining because of the sharp drop in the currency price.

This scam is not very clever, but I don’t know why so many people believe it. Of course, someone told me that I can make a lot of money every day. I want to say, will you do it if there is no sweetness, will you go to pull people, will you invest more? A MLM coin reported by Bitcoin House some time ago, an aunt was overwhelmed by the huge benefits, and finally was deceived by more than 20,000.

⑹ How Bitcoin is Calculated

In order to understand the technical principle of bitcoin, you first need to understand two important cryptographic techniques: HASH code: convert a long string into a fixed The length of the string, and its conversion is irreversible, that is, it is impossible to guess the original string from the HASH code. SHA256 is mainly used in the bitcoin protocol.
Public key system: Corresponding to a public key and a private key, keep the private key in the application, and publish the public key. When A transmits information to B, it can use A’s private key to encrypt the information, and B can use A’s public key to decrypt the information, so as to ensure that a third party cannot pretend to be A to send information; at the same time, when A transmits information to B, it uses B’s public key The key is encrypted and sent to B, who then decrypts it with his own private key, which ensures that a third party cannot eavesdrop on the communication between the two. The most common public key system is RSA, but the bitcoin protocol uses the lliptic Curve Digital Signature Algorithm. What’s the difference between cash and bank accounts? bitcoin is electronic currency, and the unit is BTC. Also used in this article to refer to the entire bitcoin system. Like opening an account in a bank, the corresponding concept in bitcoin is an address. Everyone can have one or several bitcoin addresses, which are used to pay and receive money. Each address is a string starting with 1, such as 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 will keep all transaction records and maintain the book balance of each account, while bitcoin transaction records are jointly maintained by the entire P2P network through a pre-agreed agreement. How much money is in my account address? Although software using bitcoin can see the current account balance, unlike a bank, there is no one place to maintain the ledger of each address.amount. It can only calculate the account balance in real time through all historical transaction records. 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 address B, and the payment amount is e. In order to prevent a 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 that receives the transaction information can use the public key of address A to verify that the transaction information is indeed sent by A. Of course, the trading software will do these things for us, we only need to enter 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 entire bitcoin system and needs to be elaborated. For the sake of simplicity, only the currently implemented bitcoin protocol is used here. In the current version, each network node will save all transaction information through synchronization. All transaction information that has occurred in history is divided into two categories, one is “verified” transaction information, that is, the transaction information that has been verified, which is stored in a series of “blocks”. The information of each “block” is the ID of the previous “bock” (the ID of each block is the HASH code of the block’s HASH code) and the newly added transaction information (see an actual block). The other category refers to the transaction information that has not been “verified”, and the transaction information just paid above belongs to this category. When a network node receives new unverified transaction information (maybe more than one), since the node saves all the transaction information in history, it can calculate the book balance of each address at that time, so as to calculate the Whether the transaction information is valid, that is, whether there is sufficient balance in the payment account. After removing invalid transaction information, it first takes out the ID of the last “block”, then combines these unverified transaction information with the ID, plus a verification code to form a new “block”. The above construction of a new block requires a lot of computing work, because it needs to calculate the verification code, so that the above combination becomes a block, that is, the first few digits of the HASH code of the block’s HASH code are 1. Currently, the first 13 bits are required to be 1 (approximately, not sure about the specific method), which means that if the block is generated by the enumeration method, the average number of enumerations is 16^13 times. Using CPU resources to generate a block is called “gold mining”, because the production 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 broadcasts it to other network nodes. However, this network block may not necessarily be accepted by the network, because there may be other network nodes that have produced blocks earlier, only the earliest block or the block with the most subsequent blocks is valid, and the remaining blocks are no longer used as the next block. the initial 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 starts to calculate whether the transaction is valid (that is, whether the account balance is sufficient to pay), and tries to generate blocks containing the transaction information. When a total of 6 blocks (1 direct block and 5 subsequent blocks) contain the transaction information, the transaction information is considered “verified”, so the transaction is officially confirmed, and the other party can confirm that the payment is successful. A possible problem is that if I pay the balance in address A to address B, and at the same time pay to address C, if only the single-bit transaction is verified, it is valid. At this point, my way of cheating is to generate 6 blocks containing only B and send them to B, and generate 6 blocks containing only C and send them to C before the truth is revealed. Since the CPU time I need to generate the block is very high, compared to the whole network, the probability of my success in cheating is very small. What is the motivation for network nodes to produce blocks? As can be seen from the above description, in order to make the transaction information valid, 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 get other network nodes to help produce blocks as soon as possible? The answer is very simple. The protocol stipulates that the address that produces the block will be rewarded with BTC, and the transaction fee promised by both parties. At present, the reward for producing a block is 50BTC, and it will be halved every four years in the future. For example, between 2013 and 2016, the reward is 25BTC. Are transactions anonymous? Yes and no. All BITCOIN transactions are visible, we can check all transaction records of each account, such as mine. But unlike the banking monetary system, everyone’s account itself is anonymous, and everyone can open many accounts. Overall, the so-called anonymity is not as good as claimed. But there is another benefit of bitcoin for black market transactions, it cannot be frozen. Even if the police trace a bitcoin address,There is still no way to do this unless the computer used by the exchange can be traced based on its network address. How to ensure that bitcoin does not depreciate? In general, the value of a currency is inversely proportional to the amount of currency issued when trading activity is comparable. Unlike traditional money markets, where the central bank can determine the amount of money to be issued, there is no central issuer in bitcoin. Only by producing blocks, a certain amount of BTC currency can be obtained. Therefore, the new increment of bitcoin currency is determined by: 1. The speed of block production: The bitcoin protocol stipulates that the difficulty of producing a block is fixed at an average of 2016 blocks every two weeks, and one block is produced in about 10 minutes. Moore’s Law, where CPU speeds double every 18 months, doesn’t speed up production blocks. 2. The number of rewards for producing blocks: Currently, each block produced is rewarded with 50 BTC, which is halved every four years. In 2013, the reward amount was 25 BTC, and in 2017, the reward amount was 12.5 BTC. Combining the above two factors, the speed of bitcoin currency issuance is not controlled by any single node in the network node. Its protocol makes the currency stock known in advance, and the maximum stock is only 21 million BTC

⑺ Bitcoin What is the total amount of

The total amount of Bitcoin is 21 million.

In 2009, when bitcoin was born, the block reward was 50 bitcoins. 10 minutes after the birth, the first batch of 50 bitcoins was generated, and the total amount of money at this time was 50. Bitcoin then grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward is halved to 25.

When the total amount reaches 15.75 million (the new output is 5.25 million, or 50% of 1050), the block reward will be halved to 12.5. The currency system used to have no more than 10.5 million for 4 years, after which the total number will be permanently capped at about 21 million.

Currency characteristics

1. Decentralization: Bitcoin is the first A distributed virtual currency, the entire network is composed of users, and there is no central bank. Decentralization is the guarantee of Bitcoin’s security and freedom.

2. Worldwide circulation: Bitcoin can be managed on any computer connected to the Internet. Anyone can mine, buy, sell or receive bitcoin, no matter where they are.

3. Exclusive ownership: Controlling bitcoin requires a private key, which can be isolated and stored in any storage medium. No one can get it except the user himself.

4. Low transaction fees: Bitcoins can be remitted for free, but in the end, a transaction fee of about 1 bit cent will be charged for each transaction to ensure faster transaction execution.

5. No hidden costs: As a payment method from A to B, Bitcoin does not have cumbersome quotas and procedures. You can pay by knowing the bitcoin address of the other party.

6. Cross-platform mining: Users can explore the computing power of different hardware on many platforms.
