Whisper

Whisper is a communication protocol and messaging system developed by the Ethereum project. It allows for secure and decentralized peer-to-peer messaging between nodes in the Ethereum network. Whisper is designed to facilitate private and encrypted communications, supporting topics-based messaging, group communication, and anonymous messaging. It provides a means for decentralized applications (dApps) to communicate securely and efficiently. Whisper's features make it suitable for use cases such as secure financial transactions, private messaging, and decentralized social networking within the Ethereum ecosystem.
