It seems like while everyone was busy with Zero-knowledge proof I was the first one to be able to point this out.
Fun Fact:
Many blockchain users belive that the Public-key Cryptography that is used in blockchain is more secure than symmetric cryptography, which is false.
Truth is symmetric encryption would be allowed on blockchains through a Proof of Knowledge protocol in which can only be used on blockchains that stricly enforce one-time-use addresses, Satoshi Nakamoto would not have been able to implement a Proof of Knowledge protocol due to the fact that Bitcoin has reusable addresses.
Privacy coins for the win.
