Feasibility of limiting the computational power of each node

[thecodebear]

If you add a computational power limit to each node in the Bitcoin base code, is this limit easy to crack? What I mean by cracking is not to increase the computational power by increasing the number of nodes, but can the set computational power be exceeded on a single node?

while it is possible to crack a computational power limit that is added to the bitcoin base code, the difficulty of doing so would depend on several factors. if the limit is properly designed and enforced, it should be difficult for the attackers to exceed the limit without being detected. However, it is still important for developers to carefully consider the potential risks and vulnerabilities of any changes to the bitcoin codebase.

If we can solve the energy consumption problem and fairness issue between users of Bitcoin, all efforts will be worthwhile.

There isn't actually an energy consumption problem with Bitcoin though. Bitcoin's PoW is VERY VERY good for the world. If society embraces it it can help stop enormous amounts of waste in the electrical grid and help move humanity to renewables. The only thing bad about the energy consumption is the optics: it sounds bad and the media reports about it being bad and so everyone thinks its bad and nobody bothers to learn about why its not bad and why its actually really good.

You can't do such a thing in software. You need either a hardware device to block additional power going to an ASIC (as nobody mines with CPUs anymore), or else you'd need to enforce this with a government policy that prevents mining farms from using power over X petahashes/second.
