Is there any implementation of bitcoin-based spam email control system?

[Balloon]

"Bitcoin's micropayment feature has been a killer feature for application like spam email control." I think this has been mentioned a lot. But is there any real implementation or proposal about such idea? Also some other applications like ad-hoc network, paid wifi access, tor, etc. Is there any implementation about them?

Check out HashCash and Bitmessage.

No there is not. Hashcash was the first proof of work application, and preceded Bitcoin. Bitmessage is a messaging system that requires proof of work in order to limit bloat (including spam). It is not directly based on Bitcoin, is not for email, and does not use micropayments.

Paying with bitcoins for mail? sounds like De-Fail [1] just international. People aint gonna pay for mails. They are used to it beeing free. Thats like suddently paying a special tax just to be able to use that bridge... oh wait.

spam control? Not that I know of. There is a messaging system called BitMessage https://bitmessage.org/wiki/Main_Page
I have heard about paid-wifi access but never looked into it.

No there is not.

I didn't say there was, I said 'check out'.
