Significance of drawing machine specification
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 a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design 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
mining machine is a tool for procing and mining bitcoin
Bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
rated speed: 180gh / s
wall power consumption: about 360W
power input: 12V DC input (free delivery)
size specification: 135mm × 155 mm × 300 mm (assembly bracket, fan)
network connection: WiFi / Ethernet network port, support WiFi mining
cooling mode: 12 cm PWM fan and customized radiator, quiet!
POC is the abbreviation of proof of concept, which means to provide evidence for opinions. It is a set of suggested electronic models, which can be used to demonstrate the design of teams and customers, and allow to evaluate and confirm the conceptual design scheme. The evaluation of POC may cause the adjustment of specifications and design
function:
the commitment of design and the opinions recognized by all will be recorded in the design adjustment document for future reference. In this way, POC continues to develop. If you need help completing these tasks, you can find assistance resources at Queensland University
extended data:
evaluation and verification of POC
the process of evaluation and verification is to seek feedback from risk takers through POC and filing design documents. Through POC evaluation, risk takers may put forward requirements for adjusting specifications and design
sometimes, e to design defects or inappropriate places, the design team may have to go back to the drawing board. Customers may decide to stop designing or look for other teams because the design does not pay enough attention to the needs of customers and users, or because of the instability of customer needs
sometimes the change is caused by the customer organization or project decision-maker. Generally, at the end of the evaluation and verification process, the design commitment and the opinions accepted by all will be recorded in the design documents
this is often an important milestone in the life cycle of proct development. After the evaluation and verification, POC can continue to develop
The mine card of graphics card is the graphics card used by bitcoin mining machine
Mining card is a graphics card that is specially used for general calculation to earn network currency "bitcoin". Bitcoin can be proced with specific programs, and then sold to people in need to be able to exchange real money, or mining for short
because this program needs a lot of repeated calculations, it is more efficient to use a card with more sp. Because of the full load operation all year round, there are many uncertain factors in the mining card
extended data:
mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is only hd6770, the computing power after "group" can surpass the single graphics card of most users
and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining
in fact, there are many kinds of mining devices. Guiminer, which is small and easy to use, is recommended. It can support CPU, oepncl, CUDA and other computing modes
in this way, devices including CPU and graphics card can achieve the maximum performance, and then acquire bitcoin more quickly
