Hi Bryan,

Thanks for your input.

>That's a neat trick. What about not using OP_RETURN at all, and just publishing on a tor hidden service that other wallets check? Alice wouldn't have to expose on-chain that she is a sender of a private payment.

This can be done (Tor keys can even be derived from master keys) but it's an off-chain solution, not very different from Bitmessage notifications in BIP47. As Ruben said, it won't work in an offline regime.

Alfred
