1  Bitcoin / Bitcoin Discussion / Re: Ways to prevent 51% attacks from bad actors/states on: April 14, 2023, 06:48:37 AM
I’m just curious. Would it help the network if say, 1,000,000 people each ran one miner, even if it wasn’t profitable. But it would further decentralize the network and make a 51% attack more difficult?

If so, why hasn’t there been a bigger push in the community to make this happen?

Thanks
Here's my take: if we can get a million folks to each run a miner, it would go a long way in shoring up the network, even if there's no profit to be had. This would make it significantly more difficult for anyone to carry out a 51% attack and ensure the network remains decentralized. However, let's face it, convincing that many people to run a miner without a financial incentive would be an uphill battle. Furthermore, running a miner can be quite pricey, so it's not a viable option for everyone. Nevertheless, this is a thought-provoking concept that merits further contemplation.

I agree with your take. I think it’s something that should be promoted more. What exactly are the costs of running a miner? Other than electricity and internet access? Do those things use that much power if it’s just a single miner running?

Or are you more-so referring to the actual up front cost of buying the miner? I wonder if a single miner would need to be upgraded everytime a newer model is released for it to still benefit the network? Or would a million miners that are a few generation old still have the same effect on decentralization as a million brand new, current generation of miners?

The more decentralization of the network hash rate, the better power to prevent 51% attack. However, it does not mean miners should run solo mining rig to do that task. They can join mining pools but avoid super big pools that have too high total hash rates.

You are worrying too much and in the past, some big mining pools had chance to do 51% attack but they did not do this. It's because they won't gain anything good for themselves if they make such attacks.

Bitcoin mining history
Hash rate distribution over time

Interesting links. Was not aware of all of this. So it’s essentially impossible for a 51% attack to happen at this point?
