Over time, bitcoin miners have used various methods to mine bitcoins.
As the core principle behind mining is based on the double SHA-256 algorithm, overtime experts have developed sophisticated systems to calculate the hash faster and faster.
A Complete Guide to Understanding This Blockchain Concept
The following is a review of the different types of mining methods used in bitcoin and how they evolved with time.
CPU CPU mining was the first type of mining available in the original bitcoin client.
Users could even use laptop or desktop computers to mine bitcoins.
CPU mining is no longer profitable and now more advanced mining methods such as ASIC-based mining is used.
CPU mining only lasted for around just over a year since the introduction of Bitcoin and soon other methods were explored and tried by the miners.
GPU Due to the increased difficulty of the bitcoin network and the general tendency of finding faster methods to mine, miners started to use GPUs or graphics cards available in PCs to perform mining.
Why This Matters for Blockchain Technology
GPUs support faster and parallelized calculations that are usually programmed using the OpenCL language.
Users also used techniques such as overclocking to gain maximum benefit of the GPU power.
Also, the possibility of using multiple graphics cards increased the popularity of graphics cards’ usage for bitcoin mining.
GPU mining, however, has some limitations, such as overheating and the requirement for specialized motherboards and extra hardware to house multiple graphics cards.
