especially note this comment:
> We’ve seen such attacks occur on other Proof-of-Work blockchains like Ethereum Classic, which could be a problem for Bitcoin. In addition, these pools are recognized companies and could face pressures from regulatory agencies trying to control activities on the Bitcoin network.
Have you looked into P2POOL v2? I don't know how much it can scale but it's an interesting idea and worth exploring more
IMO, the computational complexity of sha256 is the root of the problem, and nothing is going to change the advantage that fiat and government supported (covert) funding can exploit this. really, they just need to attract foreign investors to set up in USA, tax breaks on fuel and freedom to exploit stranded energy, and then declare that it's a matter of national security.
china and russia are tolerating bitcoin but unless they do the same, very quickly it's going to be BitUSD 2.0 CDBC
