Abstract (en)
[origin: WO2020212337A1] The invention relates to a method for directly transmitting an electronic coin data set between a first and a second terminal, said method comprising the following steps performed by the second terminal: receiving the electronic coin data set from the first terminal, the at least one electronic coin data set having a monetary value and a concealment value; generating a modified electronic coin data set using the received electronic coin data set; masking the modified electronic coin data set by applying a homomorphous one-way function to the modified electronic coin data set in order to obtain a masked, modified electronic coin data set; and sending a registration request for the masked, modified electronic coin data set to a monitoring authority. The invention additionally relates to a currency system and a payment system having a decentrally controlled database in the masked electronic coin data sets; and a direct transaction layer with at least two terminals, in which the method can be performed.
