Private payments
Sender, recipient, amount and balance stay private, for PCASH and for any asset issued on it.
Private money Ethereum can program.
Hold and send it without publishing your balance or who you pay. Ethereum contracts can move it, so ETH buys PCASH in one transaction with no custodian.
Rules Ethereum can drive
Anyone can write the private rules a PCASH account spends by, and rules can act on Ethereum. Ethereum contracts can move PCASH, so it trades for ETH with no custodian.
Proof without disclosure
A payment can prove where its funds came from, so a business can check it without learning who paid.
