BTC setting change address

1. Users can buy bitcoin, and at the same time, they can use computers to do a lot of calculations according to the algorithm to "mine" bitcoin. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins. Due to the decentralized programming of the bitcoin system, only 25 bitcoins can be obtained every 10 minutes. By 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

warm tips:

extended materials:

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

3. How to design the real-time display of the price on each platform in the upper right corner of the mobile phone, just set it in the school.

4. Bitcoin will set the balance of the address used for consumption (consumption address) to zero in business. When the amount to be paid is less than the available balance, it is necessary to tell bitcoin network the address to which the change will be sent, namely "change address". The change address may or may not be the address used in the original consumption.

5. 1. Your understanding is correct,
2. The bottom one on the right is the change address. If you don't understand, go to the bitcoin teaching of P2P bucks

6. Bitcoin transfer can transfer the balance of multiple addresses out or into multiple addresses at one time
for example, you need to pay Niuniu 5 bitcoins, but there are 1 / 2 / 2 bitcoins in each of your a / B / C addresses, and the balance of each address is not enough to pay for 5 bitcoins
at this time, you can initiate a transfer and transfer 5 bitcoins from a / B / C to Niuniu. Take chestnuts. If you have five bitcoin addresses, you only need to transfer one to Niuniu. You need to tell the miner when transferring money: I have five bitcoins, one of which will be transferred to Niuniu, and the other four will be transferred back to myself (can be the original address or create a new address)
don't forget to say, otherwise the remaining four bitcoins will be used as handling charges for miners. This is the change mechanism of bitcoin.

What is the sub address of bitcoin

the wallet of bitcoin is based on the HD (hierarchical certainty) framework, which has the methods of generating different addresses and managing addresses. Each public address of your wallet will be generated from your wallet's xpub (extended public key)

if you use the same address every time you receive a BTC, anyone can easily track all your payment records. This address generation method improves privacy by generating a new address (sub address) when you collect money

how to find the sub address of bitcoin

8. I opened an account in the okex exchange. The okex app has a built-in wallet and supports a wide range of digital currencies, including collection, transfer and other functions. Also, let's talk about the password of E-wallet. In order to ensure the security of bitcoin, electronic wallet must be encrypted. At the same time, encryption can't be as simple as ordinary wechat password. At least special symbols, upper and lower case letters and numbers should be arranged in a mixed way. The more digits, the better.

9. Your question is a question that many movie friends have asked. Image 1 is generally clearer in L mode than in S mode. Due to the large pixel size, it will be clearer when it is reced to a certain degree. Why do you say that? Each camera has its own resolution. For example, in a card machine, the photosensitive film may be as big as a nail plate, and in an SLR machine, it is many, many times larger, and the resolution is clearer than in a card machine. This is the reason why the SLR is clear when it is enlarged to the original size, while the card machine is hazy when it is enlarged to the maximum size. In addition, the quality of the lens is also related to it, the reason is the same. There was a personal complaint about the camera factory that his card machine was not clear. Why? When taking a picture normally, it's blurry to enlarge to the original size. It's normal for the camera factory to restore it. Due to physical factors, only the pixels have been improved, but the resolution of the lens can't be improved. Can you understand?
