FPGA chip fil miner
Mining chip has gone from CPU mining to GPU mining to FPGA mining, and now it has entered the era of ASIC mining. However, the way of mining has also experienced from one or two mining machines to small mining machine workshops, and now it has entered the era of large-scale mining
(1) mining mode: from one miner to large-scale mine
if you start to try mining, you need to prepare a miner, a computer with internet connection, an AUC, a raspberry pie, power supply and various connecting cables. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply
then other miners will start to package the transaction generated by your new package until the next package comes out first
in the future, the mining capacity of bitcoin will be small or even zero. You still have transaction fees. The system will always need miners, and mining machines will still exist.
Micro mining machine is a kind of mining machine, which is a computer used to earn bitcoin. This kind of computer generally has professional mining crystal, and works in the way of burning graphics card, which consumes a lot of power. One of the ways to get bitcoin is that users download software from personal computers and then run specific algorithms to communicate with remote servers to get the corresponding bitcoin
functions of mining machine:
mining machine is one of the ways to obtain bitcoin Bitcoin is a kind of network virtual currency proced by open source P2P software. It doesn't rely on a specific currency institution to issue, but is generated by a large number of calculations of a specific algorithm. It uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions economically
The decentralized feature and algorithm ofP2P can ensure that the currency cannot be manipulated by mass proction. Any computer can become a mining machine, but the profit will be relatively low, and there may not be one in ten years. Many companies have developed professional mining machines, which are equipped with special mining crystal. They are tens or hundreds of times higher than ordinary computers
extended data:
types of mining machine:
1. CDN mining machine
with the emergence of Xunlei game cloud, a new mining machine, called CDN mining machine, appeared. This miner, because it doesn't need too strong performance, is just a router or TV box. Thunderplay cloud uses a unique consensus mechanism, not by contributing computing power, but by contributing network bandwidth and storage space
2. FPGA miner
FPGA miner, it is a hardware base plate, equivalent to a piece of white paper, what kind of function you want to achieve, write what kind of program to it. Compared with ASIC, the chip designed for specific purpose is much more flexible
3. Cloud miner
cloud miner is relative to local mining, which can be compared with the relationship between network disk and local hard disk. In short, you can use other people's mining machines remotely through the network instead of mining machines. It can be said to be a cloud application or a rental hosting service

TSMC has proced many 7Nm chips in advance e to policy restrictions. These chips have a great impact on the mobile phone market, because TSMC is indeed a very cutting-edge and influential enterprise in the field of chip OEM manufacturing, although there will be 5nm or even higher precision chips in the future, But it is destined to be a long time in the future, with the chip of about 7 nanometers
Although TSMC is a chip foundry enterprise, its core technology and complex holding structure can ensure its market share in the future. Qualcomm Apple may compete with TSMC, but the survival of the most fundamental one is still not a problem, The profit margin may be affected to some extent, but there is no problem about the futurethe special mine card has no video output function, it's just a kind of board responsible for calculation. Strictly speaking, it's not a graphics card, but a calculation card
if you buy a second-hand card used for mining, you can only feel it in the process of using it, the failure rate of the card is relatively high, and it is easy to have symptoms such as blue screen and flower screen.
bitcoin, wikilink, bitcoin cash and Ethereum are all digital currencies. The people's Bank of China started to study digital currency three years ago and is now cooperating with the instry to develop distributed ledger. The central bank has put the issue of digital currency on the agenda.
