System and method for secure transactions to transmit cryptocurrency

An optical module for performing peer-to-peer cryptocurrency transactions, the optical module comprising:

• a memory configured to store cryptographic currency;
• an optical communication device configured to connect to an entity in a cloud infrastructure, the optical communication device comprising
• a receiver configured to receive an incoming optical signal via a first optical fiber, and
• a transmitter configured to
• generate, for transmission via a second optical fiber to the entity, a plurality of outgoing optical signals based on outgoing data streams and encryption protocols predefined for peer-to-peer cryptocurrency transactions involving transfer of the cryptographic currency, the transmitter comprising an optical modulator, the optical modulator configured to modulate light output of a laser device to generate an output drive signal, wherein the outgoing data streams include at least a first outgoing data stream and a second outgoing data stream, and
• transmit, to the entity, the plurality of outgoing optical signals, wherein the plurality of outgoing optical signals include at least a first outgoing optical signal and a second outgoing optical signal;
• and
• an application circuit configured to
• detect and extract first back-channel data from the incoming optical signal, the first back-channel data indicative of quality of the first outgoing optical signal received at the entity,
• forward error correction decode the incoming optical signal and generate second back-channel data, the second back-channel data indicative of quality of the incoming optical signal received from the entity,
• forward error correction encode the second outgoing data stream to generate the second outgoing optical signal, wherein the generating of the second outgoing optical signal includes inserting the second back-channel data into the encoded second outgoing data stream, and
• adjust one or more parameters of at least one of the transmitter and the receiver based on at least one of the first back-channel data and the second back-channel data.
