Graphical Processing Unit (GPU)

GPU is short for “Graphical Processing Unit”, and is defined as a computer chip that creates 3D images on computers. This tool is used to maintain blockchains. GPUs are also called “graphics cards”.

Blockchains require people receive, record, verify, and transmit information. That process is known as “mining”. Because mining requires computer power, people do this work in return for money. GPUs were one of the first tools used to mine.
