Oh okay! I understand you perfectly, and then your answer to my question is yes! Someone can actually possess the power to effect changes.

If that's possible, what's all the fuss about blockchain tech then?

Like I said, my knowledge on the technicalities of a blockchain is limited. But it's weird to know that someone with a lot of financial backing can tweak the blockchain to his/her bidding. Why then do we preach about decentralization?

The way I see it now, there's literally no difference with the banks that we are quick to throw jabs at.
