Before we know it, the whole ecosystem depends on these players, with all the risk that comes with this.
Shouldn't we start a movement to back out of this strangling hold, by bringing back mining to the miners at home, by limiting the production of each miner to for example 1TH/s per unique IP address ?
Sure, you can have multiple IP addresses, but suppose we'll have 100,000 miners, will there be one party that can get another 100,000 unique IP addresses to achieve the 50% attack ?
I know there will be challenges to make this happen, but still I think it is a wise move to make.
1. It will limit the electricity needed to keep the bitcoin network alive.
2. It will bring back advantages to run bitcoin mining hardware to the small miner.
3. It will limit the hashing power that can be in one hand.
4. It will make small miners enthusiastic about mining again, and the bitcoin exchange rate might go up again.
5. It's better to have 100,000 miners each making 0.036BTC/day, compared to 10 miners making 350BTC/day and leave some crumbs to the rest.
6. I am sure there are other positive things that will come out of it that I didn't think of.
There are also disadvantages to a few parties that are really big now, but I bet the majority wouldn't mind them getting small again.
I didn't think of all the technicalities needed to make this hack-proof, there are others way smarter than me to do that.
Only a typical socialist would think of this.
It's free market....get used to it.
This isn't the solution Bitcoin needs and goes against it, I think it's too late to change to perform such a change and would be suitable for some type of alt coin.
