I planned to ask this question a week ago, not that much time to check on the forum and I planned to let it drop till I saw it happening again, and I'm starting to think it a more common occurrence that I'm being able to observe normally. It was stated numerous times that the best way to make sure a transaction is not reversed would be to wait for at last 6 confirmation, and I saw that Foundry managed twice to get six blocks in a row, like in this example (this was the first):
and again yesterday
If they managed to get that many in a row this open the possibility of an attack in vase they are hacked, one single individual could invalidate thousands of transaction on top of double spending his funds, dealing not only a financial blow but what I think worse a credibility blow to the network, so how can we make sure pools don't get so much power and convince miners to move to smaller pools to avoid concentration of power and ensure decentralization?
Would there be possible to make a signalling service that would alert miners if a pool goes above 20% to switch to a lower hashrate one, much like in the days of GPU mining when you could switch the coins you were mining based on profits?
