Whisper provides decentralized peer-to-peer messaging capabilities to the Ethereum network.
In essence, Whisper is a communication protocol that DApps use to communicate with each other.
A Complete Guide to Understanding This Blockchain Concept
The data and routing of messages are encrypted within Whisper communications.
Whisper makes use of DEVp2p wire protocol for exchanging messages between nodes on the network.
Moreover, it is designed to be used for smaller data transfers and in scenarios where real-time communication is not required.
Whisper is also designed to provide a communication layer that cannot be traced and provides dark communication between parties.
Blockchain can be used for communication, but that is expensive, and a consensus is not really required for messages exchanged between nodes.
Therefore, Whisper can be used as a protocol that allows censor resistant communication.
Why This Matters for Blockchain Technology
Whisper messages are ephemeral and have an associated time to live TTL.
Whisper is already available with Geth and can be enabled using the –shh option while running the Geth Ethereum client.
