"Mining", or PoW (Proof of Work), is an important foundation of Bitcoin culture.
Today, the ARC-20 colored coin standard has such a flexible feature - the coloring process can also be "mining".
In the Atomicals protocol, the concept of Bitwork is flexibly applied to each sector, so any colored coin can be a "mining coin".
In fact, there have been countless mining coins in this circle in the past few years, and most of them are self-contained. Not to mention "using Bitcoin" or "based on Bitcoin", there are very few that are related to Bitcoin.
