US Patent 9710808 Direct digital cash system and method

Methods and systems are provided for the exchange of digital cash employing protocols for various entities to separately certify the validity of the parties, values and transactions while maintaining the anonymity of the buyer or user of the digital cash. Encrypted connections are established allowing various parties to enter into transactions to buy, sell, exchange and recover digital cash using a secure method that protects the personal information and identity of the user. The parties exchange tokens for other value in a transaction of financial settlement between themselves and wherein they are the only parties with knowledge of the amount and description of the transaction and in this way mimics a traditional cash transaction.
