If Bitcoin's original plan was total privacy, what's the essence of the blockchain?
- Total privacy wasn't the original plan.
- Just because the blockchain is transparent, it doesn't mean coins are non-fungible.
This isn't supposed to be an argument BlackHat, Bitcoin isn't fungible
The fact that you can spend
any coin at the exact same exchange rate as any other coin proves it is fungible. Literally, point me to any coin you want and I can point you to a place where you can spend it or trade it normally.
