PoW
Discussion
Sure, some sites may be okay with PoW and others want to monetize traffic
Monetizing traffic is a business model, not an alternative to Cloudflare.
Tor managed to tackle this issue with PoW, that's why I mentioned it.
I think it would depend on how much is charged (and how ubiquitous ecash is, obviously) but it could simply be a symbolic anti-spam amount.
Speaking of Tor, Cloudflare prevents me from accessing many sites when I use it
That's because Cloudflare is centralized and they can do as they please.
I believe an e-cash system would end up equally centralized: at some point only tokens from 1 or 2 regulated mints would be ubiquitously accepted...
