Instant Messaging

This chapter will cover the basics of using E2E Post-Quantum messaging capabilities through the Demos SDK.

Demos nodes automatically launch a service called signalingServer, which spins up a server responsible for handling private, end-to-end, on-node messages. These messages are then attested on the Demos network.

Each node manages its own messaging service, avoiding network-wide congestion and confirmation delays, while still forwarding attestations of the encrypted communications to the blockchain.

In the next chapter, we will learn how to use the MessagingPeer class to implement this type of communication.
