Bitcoin software running

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

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system.

2. As a new user, you just need to choose a wallet to install on your computer or smartphone. After the wallet is successfully installed, it will generate your first bitcoin address for you. You can generate more bitcoin addresses through your wallet whenever you need to. When your friends receive the bitcoin address you send them, they can pay you bitcoin, and vice versa. If your friends give you their bitcoin address, you can pay them in bitcoin. In fact, it's very similar to the way email works. So all that's left is to get some bitcoins and keep them safe. To start using bitcoin, you don't need to know the technical details
balance block chain
block chain is a publicly shared transaction record that the whole bitcoin network relies on. All confirmed transactions are included in the block chain without exception. In this way, it will be confirmed that the bitcoin to be spent in the new transaction belongs to the consumer. The integrity and timing of block chain are guaranteed by encryption algorithm
transaction - private key
a transaction is a value exchange between bitcoin addresses that will be included in the block chain. Bitcoin wallet holds a secret data called private key for each bitcoin address. The private key is used to sign the transaction and provide mathematical proof that the bitcoin in the transaction really comes from the owner of the bitcoin address. This signature also avoids the possibility of being modified after the transaction. Transactions spread among users and were confirmed by the bitcoin network in the next few minutes through a process called mining
processing mining
mining is a distributed consensus system that includes the transaction data to be confirmed into the block chain to complete the confirmation of these transactions. By mining, the data in the block chain can be stored in chronological order, the neutrality of bitcoin network can be maintained, and different computers on the bitcoin network are allowed to agree on the system state. To be confirmed, a transaction must be packaged into a block that complies with very strict encryption rules and verified through the bitcoin network. These rules can prevent the modification of existing blocks, because once there is a change, all blocks will be invalid. Mining is as difficult as winning the lottery. No one can easily and continuously add new blocks to the block chain. Therefore, no one can control what content is contained in the block chain or replace part of the content in the block chain to achieve the purpose of rolling back their costs.

3. Bitcoin has no support. As long as someone wants it, bitcoin can be used as a general equivalent and can be used by businesses. It has no value in itself. Bitcoin is not a standard currency. Gold and silver are naturally currencies. It means that gold and silver can be used as a general equivalent and it has value in itself. Bitcoin, in fact, is a credit that supports it, but this credit can be turned into not worth a hair.

4. Theoretically speaking, running at the same time will occupy your CPU and GPU, but in fact, there is always a software that doesn't work, because the one you start first will take up the computing power of your GPU, so no matter how much computing power is displayed, the second one is actually 0m / s, so there is no consequence, except that your machine card can't move, By the way, it's the best way for ordinary computers to dig bitcoin. The computing power of a card is 700m / s, and it can dig about 0.001 every 24 hours a week. According to the current transaction price, more than three yuan is not enough for electricity charges, brother. So it's better not to waste your computer and network without miner. It will effectively shorten the service life of your hardware.

5. SAMYANG has officially released its new 35mm f / 1.4 as UMC lens, and will launch six interface versions, including canon, Nikon, Pentax, Samsung NX, Sony and 4 / 3. The lens has f / 1.4 large aperture, 10 groups of 12 pieces, adopts floating focusing mechanism to obtain better image quality, and does not support auto focusing. The lens structure with 1 aspheric lens and 2 high refractive index lenses has f1.4 large aperture, and the equivalent APS frame is 49mm
