Theoretically, could widespread cryptocurrency implementation prevent DoS (Denial of Service) attacks in the future by requiring payment of a few satoshis per web server HTTP request or would the process of screening out the unpaid HTTP requests slow things down as much as the DoS attack itself?

Sorry if this has been addressed elsewhere. Searched but couldn't find anything (although I know it's been discussed as a way to eliminate email spam)...

So for AJAX to get some piece of data, you're going to create a transaction, sign it with ECDSA, transmit it to nodes, shove it into mempools, and then make a miner mine it? Sounds like a DDoS against the Bitcoin network itself.

It would be much worse. You could prepay, however, but that still wouldn't solve things, since most DoSs are caused by sheer amounts of data, and not the HTTP requests themselves.

I have recently become active again after a long period of inactivity. Cryptographic proof that my account has not been compromised is available.

Nope.

There's nothing to stop DoS attacks yet. DDoS'ers probably attack to the miners. Let's say; those miner pools stratum servers etc will be DDos'ed this time and blocks can't be found...

MaidSafe claims to be DDOS immune.

This could also ensure no DDOS attacks or server outages would occur (there are no servers).

Any significantly advanced cryptocurrency is indistinguishable from Ponzi Tulips.

I'm not saying criptocurrencies can solve the problem, but I can point your example doesn't need to be so bad, there could be a micropayment channel.
