A cryptocurrency that has the quality of being "immune" to ASIC mining is said to be ASIC-resistant. ASICs are integrated circuits designed to accomplish a specific computer task for a particular use case. ASIC hardware is made to take part in the mining of Bitcoin (or other cryptocurrencies) in the world of cryptocurrencies. Bitcoin is an illustration of a cryptocurrency that is not ASIC-resistant because of this. The protocol and mining algorithm of an ASIC-resistant cryptocurrency are set up in such a way that utilizing ASIC processors to mine the coin is either impossible or provides no noticeable advantages over conventional GPU mining. Using ASICs on coins that are resistant to them can occasionally be worse than using more traditional technology. An ASIC's role in mining is to carry out as many tries (i.e., as many hashing functions per second as possible) to solve a particular mathematical problem as is necessary. This means that utilizing an all-purpose piece of hardware, like a GPU card, is far worse than using an ASIC to mine Bitcoin or other Proof of Work cryptocurrencies. However, creating a cryptocurrency that is resistant to ASICs is a defensive game that necessitates ongoing development and adjustments. This is because ASIC designers and manufacturers are always creating new models of ASIC miners, and occasionally the newer ones can get beyond a given cryptocurrency's ASIC resistance. It is important to note that ASIC resistance is built into blockchain networks that use different consensus mechanisms, like PoS, dPoS, and PoA. Depending on the mining algorithm used, some Proof of Work (PoW) cryptocurrencies are resistant to attacks while others are not.
