1/3 of the regular CPU resources is around 1000 hashes per second according to my calculation. We would need 1 million such users to produce 1 gigahash per second. The 51% attack currently needed around 3 gigahash per second.
Yes, engaging a huge attack directly this way would mean having in the end a lot of regular users spinning up gupax.
But the main benefit here is that for me and anyone else doing that, it's practically free to run the miner.
We don't need to have a million users running gupax, it starts with 10, then 100, then 1000, then more.
We don't need to reach a million in any case. Each additional miner, as small as his share is, is a direct additional cost for the attacker.
The small miners can add hashrate for free, and the attacker always needs to compensate that and add some more on top.
Remember, this attack is expensive for the attacker, and its funds are limited.
This asymmetry is key, don't let the whale discourage the shrimps from banding together.
And as Malcom X said, don't let your enemy tell you how many of you there are.
I mostly agree, except no PoW mining is free. It requires to pay electricity, which is obvious.
You get rewarded for mining (unless you're donating your hashrate someone).
