Sounds like a plan!
With a memory-bound proof-of-work system like my Cuckoo Cycle, computing the hash could require the use of more than 4GB of memory for over 5 minutes on a 20-thread server, thus preventing the use of botnets for avoiding the expense.
- chmike 11y agoNot sure Internet providers or google will be enthusiast about this proposal. This is equivalent as asking to pay to register a new destination address. In this case the mail relay owner has to pay. It would be more fair to ask users who send mail to pay to register a new destination address. Google and mail relay provider would be more happy with this variant.
- zrm 11y agoIt's very friendly to large providers. The amount of computation needed to send to a domain is the same regardless of how many emails you send so large providers can amortize it over more emails. And large providers generally operate their own infrastructure, which implies they already have a lot of idle computing capacity during off peak hours, and "off peak" is staggered across regions. But even if some large providers refuse to hash outgoing mail, they can still verify incoming mail. The interesting benefit is that a small email provider can burn some dollars in computation once to avoid having their mail discarded by a large provider's spam filter indefinitely.
