Bitcoin (Virtual Currency)
The concept of Bitcoin (BitCoin) was originally proposed by Satoshi Nakamoto in 2009, and the open source software designed and released according to the ideas of Satoshi Nakamoto and the P2P network built on it. Bitcoin is a P2P form of digital currency. Peer-to-peer transmission means a decentralized payment system.
Unlike most currencies, Bitcoin is not issued by a specific currency institution. It is generated through a large number of calculations according to a specific algorithm. The Bitcoin economy uses a distributed database composed of many nodes in the entire P2P network to confirm and record all transactions. And use the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature of P2P and the algorithm itself can ensure that the value of the currency cannot be artificially manipulated by mass-producing Bitcoin. The cryptography-based design allows Bitcoin to be transferred or paid only by the true owner. This also ensures the anonymity of currency ownership and circulation transactions. The biggest difference between Bitcoin and other virtual currencies is that its total amount is very limited and it has a strong scarcity. 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 21 million.
A bitcoin mining machine is a computer used to earn bitcoins. This type of computer generally has a professional mining chip, and mostly uses a graphics card to work, which consumes a lot of power. Users download software with a personal computer and then run a specific algorithm. After communicating with a remote server, they can get corresponding bitcoins, which is one of the ways to obtain bitcoins.
In the currency circle, it is really clear that there are basically only two kinds of people who actively earn bitcoin: one is to organize others to issue coins and earn commissions; the other is to mine.
The mining here is not using hammer, but using FPGA, GPU, CPU, ASIC, what are these? These are chips.
Introduction to Mining Tutorial
-
find mining pool
To start mining, you must have a mining pool that is easy to operate and has stable output. Its function is to subdivide data packets for each terminal. The data packets calculated by the terminal can be paid in proportion to the corresponding number of bitcoins through sophisticated algorithms. .

Bitcoin mining begins
When we confirm that all settings are correct, click the "Start Mining" button to start mining Bitcoin, and then the graphics card will soon enter the full-speed operation state, the temperature will increase, and the fan speed will increase. You can use GPU-Z Or the graphics card driver to monitor the status. It is worth noting that because only the graphics card is running at full load, the CPU load is only single digits, so it does not affect your lightweight applications such as Internet access and office work that do not involve 3D mode.
hardware spending
Mining is actually a competition of performance and equipment. A mining machine composed of many graphics cards, even if it is only a mid-to-low-end graphics card such as HD6770, the computing power after "grouping" can still surpass that of most users' single graphics card. of. And this is not the most terrifying. Some mining machines are composed of more such graphics card arrays. Dozens or even hundreds of graphics cards come together. The graphics card itself also costs money. Counting various costs such as hardware prices, mining There are considerable expenditures.
The chips used in Bitmain's mining range from the original GPU (graphics processing unit), to FPGA (field programmable gate array), to the current ASIC (special-purpose chip). This ASIC chip is designed by Bitmain for mining Bitcoin. tape-out and production. It can be said that Bitmain is not a mining company, but a chip design company, a mining machine production company, and a mining pool leasing and maintenance company. It is said that in addition to mining Bitcoin, Bitmain also mines Ethereum, Monero, etc.
At this rate, Bitmain does not rule out the possibility of acquiring several chip companies around the world, especially in the field of FPGA. It's amazing, the field of chips is also involved in the competition rules of the Internet: it's not your peers who kill you in the end!
