Finally! Someone is taking a crack at the absolute killer app for cryptocurreny: email postage.
Think about it. Even a micro payment of a billionth of a penny would kill off most spam (and probably a lot of phishing, too).
So, when you send email to me at:
you will get a reply demanding that you pay postage. (Please use bitcoin–if I get any, it will go to charity.) Then the original email will be delivered.
This service is far from perfect. At the moment, there isn’t any way for me to send email from this address, which means that any mail I send exposes a non-metered address. This can be fixed.
It seems to me that, in the long run, I’d like to have this automated, so I can effectively attach postage when I send it to someone. This way, I can exchange with friends and colleagues, recycling the postage automatically.
I’d also like this integrated with filtering, so I can charge different rates, e.g., for family (zero), business (a contracted rate).
Alternatively, it might be interesting to let me attach as much postage as I want, indicating my urgency/interest in reaching you. This is sort of a bidding process, where I might be willing to read you spam if you paid enough to get my attention. This kills off mass mailings, and gives me a way to indicate that I really want to contact you, specifically.
Finally, I’d love to use Dogecoin for this. It’s just the kind of thing Dogecoin is meant for. In general, it should be possible to specify what currencies you will accept for postage, and maybe the system can automatically convert.
My real “composed” address is:
