<div dir="ltr"><div><div class="gmail_extra">Gmail Spam Filtering seems to perform reasonably with the heterogeneous mix of PGP and clear text email that I currently receive. I have noticed that encrypted emails from new contacts occasionally take additional time to be delivered. But I've got insufficient observations to disambiguate this from the normal stochastic variation of gmail delivery times. Do we imagine that the existing system only begins to fails once e2e traffic approaches some critical threshold? <br><br>If this is a case, what we need is a system for gradually adding new cryptographic reputation signals as we approach that threshold.<br><br></div><div class="gmail_extra">One thing I like the about the cryptocurrency transaction idea is that it adds a server readable cryptographic reputation signal to the message. The emails would be constructed as message which is signed by sender key then encrypted to recipient public key then signed by emails service's cryptocurrency key. The third signature and a corresponding cryptocurrency ledger transaction to enhanced deliverability in fully optional manner.<br></div><div class="gmail_extra"><br><br><br><div class="gmail_quote">On Fri, Sep 5, 2014 at 10:04 AM, Tim Bray <span dir="ltr"><<a href="mailto:tbray@textuality.com" target="_blank">tbray@textuality.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div style="font-size:small">Tremendous piece, Mike; Thanks!

The first idea people have is to make sending email cost money, but that sucks for several reasons; most obviously - free global communication is IMHO one of humanities greatest achievements, right up there with putting a man on the moon. Someone from rural China can send me a message within seconds, for free, and I can reply, for free! Think about that for a second. </div></div></blockquote><div><br></div></span><div><div style="font-size:small">1. Is there a price point for an electronic “stamp” which is close enough to free to be acceptable even to someone in rural China (I dunno, say 0.001USD) but unaffordable for spammers?</div><div style="font-size:small">2. Could cryptocurrency tech provide a mechanism for creating/vending such stamps?</div></div></div><br>
