GPU mining
Graphics Processing Units calculate cryptographic hashes to verify transactions on a decentralized ledger. Miners receive rewards for performing this computationally intensive work. GPUs proved especially performant at calculating these specific hashes compared to other hardware. Early cryptocurrency systems relied on central processing units to mine coins in their earliest days. These processors were gradually replaced by more performant graphics cards as the technology evolved.
The first public implementation of Bitcoin arrived in early 2009 without GPU mining capabilities. Graphics Processing Unit mining devices emerged in October 2010 through new software configurations. June 2017 marked a turning point when Hong-Kong based Sapphire Technology produced GPUs tailored specifically for mining tasks. Many of these specialized units lacked display functions and could only be used for mining operations. This shift created dedicated rigs that incorporated multiple GPUs working together to maximize output.
Statistics suggested that 67% of electricity powering Bitcoin mining during 2020 and 2021 came from fossil energy sources. Bitcoin mining produced more than 85 million tons of CO2 during that same period. Cyber criminals began hacking into computers to perform small mining tasks in the background. Hackers typically limit the amount of GPU power by 75% to stay undetected while using a small portion for cryptocurrency extraction. This malicious activity targets consumer devices to generate unauthorized revenue streams.
Cryptocurrency miners increased their purchases of GPUs between 2013 and 2017 causing prices to skyrocket worldwide. A report by Bloomberg suggested that cryptocurrency miners spent $15 billion on GPUs during the mining craze since 2021. The increasing demand caused a shortage that continued until production finally caught up in 2023. Prices stabilized as the market adjusted to new conditions following the end of the boom cycle. Global supply chains struggled to meet the sudden surge in hardware requirements.
Ethereum finished its transition from the traditional Proof of Work algorithm to a Proof of Stake algorithm in September 2022. This change significantly reduced computational costs and made it economically infeasible to use GPUs to mine Ethereum. Miners began dumping their graphics cards onto the second-hand market immediately after the transition. Some GPU miners switched to other Proof of Work coins like Ethereum Classic though these alternatives remained unprofitable. Mining companies started refactoring systems to house AI computation in early January 2023.
