NXT :: descendant of Bitcoin - Updated Information

[jl777]

I am assuming that it is possible to configure firewalls to only accept incoming connections on specific ports to a list of specific IP addresses.

Could somebody confirm (or deny) this assumption?

I want to create a set of guardian servers that are the only ones that accept connections from random clients. The servers that actually do the "money" work, would only accept incoming connections from these guardian servers. This would isolate the pool (and multigateway) servers from the internet and I think provide good protection.

This way, we can make doing a Ddos attack require attacking all of the guardian servers. Since these guardian servers really only need to run a very small validation and relay layer, there is no reason the work of the guardian servers couldnt be spread across a large number of servers. Not quite fully decentralized, but a lot less vulnerable than having a single pool server.

James

yes, any hardware based firewall or freebsd/linux pf/iptables can do this

Cool!
I dont want to mess with iptables, but I will write the software so it is easy to figure out what the approved connection paths are

Huh, at the end it allways come down to a matter of trust...

But you are talking about trusting the other part you deal with,not an intermediary or someone who holds your money.It is your responsability who you make deals with.

Hello, my name is James.
I rebooted and feeling much better

Thanks to all the generous donators!! I am feeling very optimistic today.

For all the controversy the "coin that shall not be named" has created, at least people now are seeing NXT for what it can do. The idea of a middlecoin that pays out in NXT is a very good one. https://bitcointalk.org/index.php?topic=345619.msg5694336#msg5694336

I authorize 20,000 NXT from NXTcommunityfunds for this bounty.

I would also like to authorize 50,000 NXT to wesleyh for his fantastic web GUI. With matching amounts up to another 50,000 NXT for any directed donations to NXTcommunityfunds for him. Just send donation to 13776816462073143763 , post txid, amount and that its for wesley.

We need more testing. The first of the testing bounties:
antanst should get 10000 NXT for crashing testnet
l8orre should get 5000 NXT for making freerider that will help others crash testnet

James

Hey james, thanks a ton for your recommendation! I haven't asked for it, but it would of course be fantastic to receive this amount as I have put a ton of work in my client already

Thanks again.

No, thank you!!

All of NXT benefits from an easy to use client.

I estimate that it easily boosts the value of NXT by 2%, realistically a lot more as it brings NXT to the mass website using public. How many people use websites, but are not comfortable with downloading software, loading blockchain, etc.?

The 50,000 NXT is around 2% of NXTcommunityfund

NXT peoples, lets reward people who deliver software that boosts the value of NXT. This will set a good precedent and show others that if they deliver software that boosts NXT, the NXT community will reward accordingly. It is this message that I want to reinforce.

James, please send me a PM documenting in one place how much from NXTcommunityfund you want to go to who.

Hello guys,

on m'a dit de participer au topic. Donc je le fais.

Le Weekend, il faut boire des bières et sortir. Ca permet de ne pas se prendre la tête. Ça permet même d'avoir des idées de business pour NXT.

Keep cool. And have fun !

Ludom

NXT AT PROJECT HELP.  NEED JAVA PROGRAMMER.

This is a request by CIYAM for help with AT.  Need to get on this asap

Quote:
The first thing we are going to need is a Java programmer to convert my C++ prototype (and yes I want the Java code to use the console so we can easily run test cases).

Unfortunately CfB isn't interested in doing this in a way that would allow for proper testing so I'd rather he wasn't actually involved in AT other than providing assistance with the Nxt AT API side of things (i.e. how Nxt AT can send and receive transactions as well as get other information and some general functions like say testing a hash value).

Anyone interested in helping CIYAM?

I helped you, new topic here: https://bitcointalk.org/index.php?topic=515980.msg5702106#msg5702106

Interesting for participating to this project and rewrite some part of code or function in java, help for debugging, etc ...
Unfortunately i'm full time project director. Community need to hire full time java developper.

Especially this concept of "Turing complete" set of byte code instructions is very interesting.
I hope other people will join this project.

If you want decentralised and DDOS protected from random nodes - could you use an encrypted multicast that the guardians are listening for??

http://en.wikipedia.org/wiki/Multicast

then use IP firewalls for the guardian/guardian links which I would still authenticate with certificates on each server...

Great,wesleyh antanst and I8orre all should be rewarded for their works,especially for the GUI.

I think it would be simpler if the pool server just polled all the guardians every block. At ~100 guardians, it shouldnt be a problem. If scaling up becomes a problem, I can go to a tiered system, where the pool server polls all the first tier guardians, which in turn pool their respective second tier guardians.

The total traffic is the same and might as well have it as controlled as possible

Maximum items of an asset is 1 Billion.What would happen if many billion doges were in the asset exchange??There is a supply of 60 Billion,and other coins may have even more. Does it matter for these assets with gateway?

yes it would matter. If it looks like we will run out, we can always add kiloDOGE or even megaDOGE

Nxt Mining Pool Bounty posted @ Nextcoin.org

https://nextcoin.org/index.php/topic,4399.0.html

Initially seeded with 20k, please feel free to follow the link and donate additional funds to the posted address.  My initial 20k are being sent to that address (from cryptsy) hopefully they will show up before Monday.

All, the bounty is now over 120,000 Nxt.  Thanks to the additional donators!

[slothbag]

I agree the GUI looks fantastic and Wesley should be rewarded.. But what about jean-luc? Without him NXT would be dead in the water shortly.  How much does jean-luc get paid or has received in donations?
