It seems, that you and BCNext need to find a way to modify Jetty core, or something, to make Hallmark-based (at least) protection.   To buy expensive VPSs, wich would be the first target  - it is not a is not an option ..  it is centralization ...

Jetty has http://wiki.eclipse.org/Jetty/Reference/DoSFilter... But I prefer to leave this work for those who know Jetty much better than me.

Added support for CORS

Yes, this can be used for DDoS. I disabled it in 0.4.3e.

may be something wrong with newest versions (0.4.1e and 0.4.2) ?

my 0.4.0 VPS with well-known (bootstrap) IP can work ~2 hour before "java.lang.NullPointerException", whereas my anorher VPS 0.4.2 with unknown (for public) IP hardly survive 30 min.


Nothing special AFAIK, maybe BCNext added something, I don't review all the changes...
  - may be this?  no?
Ddos is incoming requests, push and pull r for outcoming ones. Also it targets Jetty core, not Nxt servlet.

How do I get an alias? I own NXT and I want to get some aliases


https://localhost:7875/alias.html


If you get a transaction number instead of a message saying that the alias is taken, do not process the request again because it will count as a reassignment and you will be charged with fees again. You can be absolutely positive the alias is yours after 720 confirmations.
Thank you very much for that.

ALL THESE SHOULD BE INVISIBLE FOR THE AVERAGE USER!!

sorry CfB, how can the network avoid these type of attacks in the future?

1. More nodes (some guys r working on that)
2. DoS protection (ask ur hoster)
3. Hallmark protection (not activated yet)
4. Switch to binary protocol (saves 10x bandwidth, but increases entry barrier for new programmers)

Agree with you 100%, but when is the decentralised exchange going to be released?  And, when it's released, how is it going to avoid DDOS?

Planned by the end of Jan. To DDoS the exchange an adversary must DDoS the whole network.

Edit: Actually, we r waiting for client. Server part is ready.

In other words, not only are the attackers losing the war, they technically didn't even win this particular battle.   Wink

There must be some other NXT exchanges coming online.  Does anyone know of any?

Why do we need centralized exchanges?

As you said, I think you need more seed nodes and improvements to the protocol for it to scale enough to handle the decentralised exchange.

I thought the whole purpose of a purely PoS system is that attacks were not possible this way.

What way?
Using proof of stake

Current DDoS attack has nothing common with proof of stake.

You guys need to get more Seed nodes up.  We know you can afford it, so get going.
