Is there some kind of implementation in bitcoin to communicate between nodes, which is similar to the Whisper Communication in Ethereum ?
Whisper, is a communication protocol for DApps to communicate each other without using the Blockchain and Dapps are something in ethereum which is called as Decentralized Applications, which are created using smart contracts.
Could you perhaps summarize what Whisper is used for, so that potential answerers don't have to research your question first if they aren't familiar with Whisper? – Murch – 2016-06-13T17:21:02.860
