Assuming that blockchain or BTC completely ignored privacy, would this make transactions faster, less costly...etc.?
Or it is technically as is?
if we could turn back the clock where the bitcoin wasn't launch at full blast then we could ask the developer about this assumption but now it is too late to change the bitcoin protocol as it coin circulating reach to maturity level as high as 80 percent, and it is not easy to rewrote or re-implement new protocol once the infrastructure had been establish and a huge amount of money was invested to run the bitcoin industry, it is hard to take down and begin again from scratch.
I understand, till now nobody can travel back in time.
What I am thinking is not starting from scratch, just developing, modifying the software, the protocol or whatever to accommodate the required changes. Software can be always and continuously modified to perform faster and faster, and cheaper, without re writing the whole application from scratch. This is the software part.
For the hardware, miners can still keep mining and solving the problems as usual using the same hardware.
They might lose some of the profits, but they might gain more if the amount and speed of transaction is increased and more people use it.
May be w need to think something like torrents, p2p...
What you think?
