1. An optical module configured to control a peer-to-peer transaction, the optical module comprising:
a silicon photonics substrate;
memory formed on the silicon photonics substrate and configured to store a private key;
application circuitry formed on the silicon photonics substrate and coupled to the memory, the application circuitry configured to (i) receive, via an external interface, an electrical signal carrying instructions for executing a digital financial transaction, (ii) verify the digital financial transaction using the private key stored in the memory, and (iii) selectively generate a transaction message including information for completing the digital financial transaction; and
optical communication circuitry formed on the silicon photonics substrate comprises a direct-to-cloud interface and responsive to the application circuitry, the optical communication circuitry configured to (i) generate an optical signal based on the transaction message, (ii) generate a strict phase reference for the optical signal using a local oscillator, and (iii) transmit the optical signal via the direct-to-cloud interface to at least one remote entity securely based on the strict phase reference generated using the local oscillator.
