Great interview! The whole proof-of-work approach is fascinating, and reminds me of a very old email concept he mentions in passing, where an email server would only accept a msg if the sender agreed to pay like a dollar. Then the user would accept the msg, which would refund the dollar. So this would end up costing legitimate senders nothing but would require spammers to front way too much money to make email spamming affordable. In his version the sender must do a processor-intensive computation, which is fine at the volume legitimate senders use but prohibitive for spammers.
The creator of Anubis did an interview on the Selfhosted Show podcast a little while back and explains this in detail, and it’s worth a listen.
Here’s a time stamped link for the interview
