Title: Can DDoS of Ripple validators freeze all transactions? Post by: Come-from-Beyond on September 27, 2013, 12:34:18 PM Simple question:
If Ripple validators are shut down due to a DDoS attack, will transactions be processed? Title: Re: Can DDoS of Ripple validators freeze all transactions?

As validators do not need to advertise their IP address they can be hidden. It is unlikely that hidden validators can be specifically targeted with a DDoS flood of Internet traffic.Title: Re: Can DDoS of Ripple validators freeze all transactions?

What about my question, btw? Title: Re: Can DDoS of Ripple validators freeze all transactions? Post by: ahbritto on September 27, 2013, 04:44:38 PM Hidden validators?

No particular validator is vital.What about my question, btw? Title: Re: Can DDoS of Ripple validators freeze all transactions?

So Ripple can't be easily shut down with a DDoS attack. Thx. Title: Re: Can DDoS of Ripple validators freeze all transactions? Post by: Sukrim on September 28, 2013, 01:11:02 AM Well, currently there are not THAT many servers out there, so a DDoS on all known node IPs might be at least quite disruptive. Killing only a few validators, even highly trusted ones though should(TM) not be problematic - also since they do only publish a signature per ledger and that's mostly it, so a validator can be easily relaunched on VPS servers or hidden behind known good nodes.
