[ANN] [PPC] PPCoin Released! - First Long-Term Energy-Efficient Crypto-Currency

[doublec]

Is there a way with the RPC API to identify when the last PPCoin checkpoint occurred? So a merchant/exchange can know a safe point where a transaction won't be rolled back?

Yes it's already included:
ppcoind getcheckpoint

Although in the long term (say a year maybe) ppcoin network will be decentralized similar to Bitcoin so one shouldn't get used to depending on this.

Thanks. I'm mostly concerned about checkpoints for now since ppcoin is so new and the blockchain aspects of it are less understood (by me anyway). I've set up a bitparking ppcoin exchange and I'll see how it goes as to whether it's a long term thing or not.

...

Yeah, I could try that.

Is there anything special about the pushpoold NothingG is using?  I'd rather just start up my own PPC pool.

ppc.kattare.com?  heh.

I run a bog standard pushpool setup with my pool, seems to work just fine.

I'm correct in my math.  60 servers x 16 cores x 2.5Mh = ....  

I was being conservative at 2,000Mh.  It's actually a bit higher.

I run the ltc.kattare.com pool, I have a semi-decent idea how it all works.  

Hi burnside,
  Looks like I have reproduced the issue with cpuminer on testnet. I will continue to look into the cause in the next few days and will update if I have more discoveries.

Awesome, thanks!

Is 'getmemorypool' returning the wrong coinbasevalue for PPCoin? it currently returns '1298080000' but the last block minted was '1298.17000000'. 1298080000/1e8 = 12.9808. Or am I miscalculating something?

If amount is represented in integer ppcoin is only precise to micro-ppcoin, so if an application needs to interpret raw data it needs to be aware that 1 ppcoin = 1e6 rather than Bitcoin's 1e8.

Hi burnside,
  It seems that recent code in cpuminer broke something. When I switch to cpuminer v1.0.2 it appears to work fine. Which version of cpuminer were you using?

Yeah, I tried 2.2.1 and 2.2.3.  Unfortunately 1.0.2 is about half as fast as the newer ones.  I'll give it a try overnight anyway.  

Any idea what would keep 2.2.x from working on PPC, when it works for BTC?

Well guys it took me a long time but I finally built the windows GUI client.

Not looking good on 1.0.2:

No newmint's either.

This is normal on old cpuminer versions as they submitted difficulty 1 shares always. This means you get a bunch of false proof of works for those that don't meet the actual target difficulty.

I've updated the link in my first post, turns out I forgot to include the libraries needed because QT doesn't do it for me :S.
