Hi Guys,

It's been a while since Ixcoin was updated. Would anyone be interested in working on the client? Here are some things which would be great to implement:

• Update to latest Bitcoin client's code
• Switch away from LFnet to another IRC server

(updated)

• add seed nodes
• Update the website

I can work on updating the website. I think we're better off having the IXC forum here as running a separate spam-free forum is quite a bit of work. Same goes for a wiki - static pages will be easier.

If you're willing to help, I can contribute some IXCs. If others cannot contribute to the coding effort, then they can also help with some IXCs too. I'm happy to hear any other suggestions.

It appears OpenCoin, the creators of Ripple, have borrowed a similar model to Ixcoin's. A certain amount of IXC were reserved for future development of the currency e.g. to fund developers, advertising and prizes. About 30% of all XRPs are reserved for this and a further 20% appears to go to the currency founders.

Opencoin currently has a 100% control of XRPs, so it is hard to predict the uptake level by the btc community of such a model.

How will Opencoin deal with Ripple clones offering 100% distribution of the XRPs once they release the source code will be interesting.

The Ixcoing.org website was deleted as the VPS expired a while ago. So, I've got a new hosting plan and salvaged the homepage. I'd like to put the wiki backup when I get a chance. If anyone is interested in helping putting Ixcoin back on track, I'd be happy to accept help getting content back up for the wiki (ixcoin background/history) and anyone who'd be interested in porting Ixcoin to the new Bitcoin client or maybe using Multicoin.

Ixcoin.org is back up

Ixcoin.org should be backup soon. In the meantime, you can always download the Ixcoin client here: http://sourceforge.net/projects/ixcoin/files/ixcoin-0.3.24.3/

Apologies for any inconvenience. Should be back up soon. Will keep you posted.

15,000 IXC sent to DoubleC for first half of merged mining bounty.

We'll stick to Bitcoin's transaction fee scheme for now - except if it becomes apparent in the future that changes need to be made.

Thanks for the tip and build. I'll modify the build file when I get a chance. Do you happen to have a link to the build so I can include it on the ixcoin.org?

EDIT: committed fix  https://github.com/ixcoin/ixcoin/commit/5c2d93addcf72b41d1e074d60167b9a514966384

Distro files are out: https://bitcointalk.org/index.php?topic=54977.0 for details.

We've made some changes to Ixcoin to implement Artz's 51% time attack and to support merged mining. This is a compulsory update otherwise your Ixcoin client will not communicate with other updated nodes after block 43,000. The blockchain remains intact.

What's new in 0.3.24.3?

• Fix for Time-Travel Attack to Difficulty Algorithm
  
  This is the Artz Fox fix for the timetravel exploit. Takes effect on block 43,000. (commit)
  
  
• Merged Mining Support
  
  DoubleC added support for merged mining. Takes effect on block 45,000. (commit)
  
  
•   Other Miscellaneous Changes 
  
  * Blockchain lockin at block 36,500 (commit)
  * Added bitparking to seed nodes (commit)
  * Removed DNSseeds (commit)
  
  

Where can I get the source?

The latest source is available at https://github.com/ixcoin/ixcoin

Where can I get the executables?

On Sourceforge:

ixcoin-0.3.24.3-linux.tar.gz

ixcoin-0.3.24.3-linux-src.tar.gz
   
ixcoin-0.3.24.3-win32-setup.exe

ixcoin-0.3.24.3-win32.zip

Looking forward to your comments. Thanks!

Thomas.

Attached are the Windows and Unix binaries for Ixcoin 0.3.24.3 which incorporates DoubleC's pull requests for merged mining and the 51% attack fix.

Unix binaries: http://dl.dropbox.com/u/38736424/ixcoin-3.24.3-dev/ixcoin-unix-0.3.24.3.zip
Windows binaries http://dl.dropbox.com/u/38736424/ixcoin-3.24.3-dev/ixcoin-win-0.3.24.3.zip

The 51% fix takes effect on block 43,000 and merged mining on block 45,000

Please test the binaries on your platform and let me know if you have any issues. Also, I welcome any coders to review the recent commits https://github.com/ixcoin/ixcoin/commits/master

If you prefer to build from source, please go to https://github.com/ixcoin/ixcoin

Once I've had some feedback, I'll release the builds on ixcoin.org & co. (or apply any corrections as necessary).

Thanks.




 

Hi guys,

Apologies for the delay. Anyway, I'm back.

Thanks for the submitted changes DoubleC. I will have time to look into these tomorrow and hopefully get something compiled and distributed.

Once it's all up and working, I'll send doublec the well-earned bounty.

Thanks for your patience guys.

Hi DoubleC,

The timetravel fix is a one-liner so that's no biggie, but if you can add merged mining successfully then yes that would be sufficient. I'll hopefully be able to compile and then release the new distro.

Thx!

Not at the moment, but I could be wrong. When we switch over to merged mining, Ixcoin should get more exchange uptake.

Ixcoin.org is now back online after issues with the DNS were fixed.

We're still looking for someone willing to port merged mining to the Ixcoin distro (and even upgrade to the bitcoin 0.5 codebase). If you're interested, the current bounty is 30,000 IXC.

Anyone who wants to can't contribute coding is welcome to contribute to the bounty at xvqw8p6smpLmLbXhLaDhjvuEhKdkTXhscP

Thanks.

Thanks for the suggestions as to who to contact. Any other suggestions are welcome.

I've received a 500 IXC donation towards the fund.

I might add more indeed. I would hope others also chip in too since the value of their Ixcoins is at stake.

Any suggestions as to who I could contact who is sufficiently knowledgeable in merged mining?

I'm still looking for someone to help with coding merged mining into Ixcoin. I've had no volunteer yet.

If you cannot volunteer coding skills but would like help, then you can send Ixcoins to xvqw8p6smpLmLbXhLaDhjvuEhKdkTXhscP. These will be added to the 10K Ixcoin coding bounty for anyone that adds merged mining to Ixcoin.

Yes, solving the time travel exploit wouldn't take much coding effort. However it wouldn't necessarily guarantee sufficient miner uptake for exchanges to be confident about potential 51% attacks. I believe merged mining would address this. Plus I'd rather include as much as possible in the next compulsory update, rather than having myself and all users go through the new release process twice.

Ixcoin.org should be back up soon.

Looking into merged mining. Anyone who wants to help with the coding can claim 5K from the 10K Ixcoin coding bounty.
