Trusted intermediaries say goodbye
Peer to Peer trustless transactions -

Bank, and mastercard were eliminated and all there is is the exchange between two or more indviduals a digital signatures.

The public signature can only be unlocked by the receipts private key. Meaning if the user keeps his private key secret and only releases his public key like a email address almost no one should be able to crack the encryption anytime soon.
