You are welcome. One thing to note though, the max os x build is actually 32 bits, and should be runable on both 32 and 64 bit systems.

Re: Namecoin is Prime for a 51% attack

nice try twobits, none of those hashes exist... grrr but hey thanks for implementing the method, I would put my custom block hashes in place I took the hashes from zamgo's patch I linked to. I compiled and ran it on a virutal machine, and with those checks in place it successfully downloaded the bl...

Re: Namecoin is Prime for a 51% attack

Can this be hardcoded into the namecoin client software? Please provide an updated client version that will revert back to block 19100 once this attack is over. Run a client that has a recent checkpoint and it'll refuse to accept any chain that was rewritten before that checkpoint. Are you able to ...

Re: I will do my best to get miners, what's plan B?

May I suggest a miner only namcoind that will reject blocks outside of a trusted group of miners pools? I'm just throwing ideas out here any one care to chime in? Get as many as possible, especially pools to upgrade to a checkpoint protected version of namcoind such as https://github.com/zamgo/name...

Re: Namecoin is Prime for a 51% attack

We are different people and our differences need to be set aside for a common goal. I do not disrespect your attitude even though I do not agree with it because I know differences is not a bad thing, we all can't act the same way or we would be Borgs. Try not to take offence to anything I say, if y...

Re: New NameCoin Mining pool [No wait payouts 10+ Mhs]

Due to the possibly upcoming attack of BitcoinEXpress ( http://bit.ly/poTuzs ) nmcbit will not pay out NMC for your safety. All your namecoins are safe. That may not be true. Since there are no checkpoints in the nmc clients, if he really wanted to he could go back and rewrite history. Depends just...
