Diversifying PoW with RandomX and/or other algorithms

In a perfect world yes, that would fulfill the dream of decentralized mining and distribution. That was the reason Equihash was selected as the Zcash mining algorithm in the first place:

Equihash is a memory-oriented Proof-of-Work, which means how much mining you can do is mostly determined by how much RAM you have. We think it is unlikely that anyone will be able to build cost-effective custom hardware (ASICs) for mining in the foreseeable future

But sadly that’s not what ended up happening. Bitmain figured out how to make an ASIC for Equihash and we didn’t change the algorithm.

Where there’s money to be made someone will spin up a bunch of Amazon CPU instances or design an ASIC and the regular guys with their laptop CPU will be left in the dust because the difficulty adjusts so high finding a block becomes impossible.

Which is why I suggested:

You can’t beat the game but you can try to level the playing field.
