We've been talking about the need for private messaging on Memo. Separately - it's a tricky thing to put messages on a public blockchain and claim it's forever private.
Is there a way to send a text through BCH but not saved on the Blockchain? Something like Counterparty/Omni; secured by BCH but not stored on BCH itself if I understand correctly
You could store a hash of the message on-chain, so the tx would only verify a message, not store it. This way, if logs get leaked, they can be verified.
