What is GPU mining? Since the beginning of the 21st century, cryptocurrency miners have been adjusting their software and hardware to meet the high power requirements needed to solve the complex mathematical problems needed to safely handle transactions. GPU is traditionally used to support the rendering of visual effects or graphics, so the computer CPU does not have to deal with the tiny details of video or games. They are now more widely used in cryptocurrency mining equipment to break up blocks in the chain. When did the GPU start mining? This article will answer for you.
1、 What is GPU mining?
Processing approved transaction blocks in the cryptocurrency blockchain requires a high level of power consumption. In order to process transactions and complete large-scale PoW, cryptocurrency currency miners built professional computers that use a combination of software, hardware and processors to quickly solve complex mathematical problems and algorithms.
When cryptocurrency first appeared, the processing of blockchain was completed by the CPU of the computer. However, as more and more people begin to join the cryptocurrency mining, this makes the mining process more difficult; Additional processors are needed to mine cryptocurrencies quickly and efficiently.
Application specific integrated circuits (ASICs) are another major type of processors used for cryptocurrency mining. Built for this purpose, they are generally considered the best processor choice by miners. In contrast, GPU mining uses graphics cards or GPUs to verify cryptocurrency currency transactions on the blockchain.
Originally designed to process visual information, GPUs and graphics cards can be reused for parallel computing mathematical operations, and are part of the first batch of devices upgraded from devices using CPUs.
In addition, in order to solve the mathematical problem of protecting cryptocurrency transactions, the GPU system uses a hash algorithm. This algorithm maps arbitrary size data into a fixed size hash to help computers solve problems. The most common hash algorithm used in GPU mining is SHA-256. The computer converts it into an output, which is always 256 digits.
Other algorithms used in GPU mining include:
Scrypt: It runs on password based key functions, and the block generation time is about 2.5 minutes.
X11: The most energy-efficient algorithm, which uses 30% less watts than GPU, and is designed to resist ASIC.
Ethash: It was formerly called DaggerHashimoto, which was also developed for the purpose of resisting ASIC. It is mainly used for Ethereum, Ethereum Classic and Extended Currency.
2、 What is the starting point of GPU mining?
GPU mining began to increase gradually in May 2010 when Lazlo Hanyecz bought two stick John Pizzas with 10000 bitcoins. This gives cryptocurrency its inherent value and leads to the growing popularity of bitcoin mining. In addition, the code enabling Bitcoin GPU mining was released to the public in October 2010.
In this regard, the relatively affordable cost of GPU and graphics card and the ability of GPU mining machine setup have led to the development of this mining technology. In addition, building an equipment with GPU does not require very complex technical knowledge or huge computer capabilities. Because this is a setting designed mainly for mining enthusiasts, until the introduction of field programmable gate arrays (FPGAs) and ASICs, the mining machine became powerful enough to turn cryptocurrency mining from a sideline into an industry.
What is the above content for GPU mining? When did the GPU mine? The answer to these two questions. In short, GPU mining uses one or more GPU cards to mine cryptocurrencies. GPU can process hashes faster than CPU, but not as fast as ASIC. Due to the high mining difficulty of Bitcoin, GPU mining machines are usually reserved for mining counterfeit coins.
