Abstract
This proposal implements the capability to securely exchange encrypted messages on-chain. Users can register their public keys and encryption algorithms by registration and subsequently send encrypted messages to other users using their addresses. The interface also includes enumerations for public key algorithms and a structure for user information to support various encryption algorithms and user information management.
Objectives
- Provide a standardized interface for implementing messaging systems in smart contracts, including user registration and message sending functionalities.
- Enhance flexibility and scalability for messaging systems by defining enumerations for public key algorithms and a structure for user information.
- Define events for tracking message sending to enhance the observability and auditability of the contract.
- Using a custom sessionId allows messages to be organized into a conversation.
