I'll just keep mining on my Phenom X4 Tongue

This allows secure transactions to be made much more quickly; six confirmations may take fifty minutes in Bitcoin, but they take only six minutes in Primecoin. The underlying mathematics behind why six confirmations is a fairly safe threshold is independent of block confirmation time, so the Primecoin transaction at six confitmations is no less secure

Other than that, great article, I finally know about Primecoin. Great alt for once!

Had a dream I mined some of this. Woke up to find out it was disconnected instead. Zero XPM. Ah well.

PPS down to 149 on my stock i7-3770K now but 2nd block (19.78) found in 4 hours! Smiley

i5 Mobile at about 85 PPS for 2 hours and nothing so far.

Correct me if I am wrong but isn't there already an existing set of prime numbers that are known?

Would this not be applicable to the proof of work function here?

There are infinitely many primes. However, the table of known primes is rather big and increasing all the time. New primes are huge and it takes weeks/months of computing power to find them, so I don't think this project can actually find any new ones.

So in a way, I believe you could use the list of known primes, but then it becomes a memory-bound problem, and it's probably faster to use other tests than search through the list.

I mined for 2-3 hours at the initial release with no blocks found. Decided to turn it back on while I slept. 6 hours later, I woke up to find I had discovered 2 blocks. Not too shabby I guess. I might continue to do this, but it's too damn hot to leave it running during the daytime.

Seriously this i7 machine has been running 100% on 8 cores for over 14 hours and not one reward?

If we can't join a mining pool and at least get rewarded for the amount of work we put in, whats the point? we are just gambling with our time. This can't be a serious contender in the coin game without a guaranteed ROI for miners.
This needs a mining pool, or people are going to get disillusioned, fast.

For anyone interested, digitalOcean's $0.007 (7/10ths of a cent) per hour server slice gets around 15-22 PPS. However, their 8-core $0.23 gets around 2. Sad

Let's see what happens by morning.

Guaranteed ROI?

*facepalm*

Point me in the direction of a coin that guarantees ROI.

Can someone with more software/hardware knowledge explain me what will it take to develop a GPU miner for this, and how long should we expect to wait for something like that? Is it harder to do than it was with YAC?

GPU mining is absolutely pointless. A public GPU miner will only drive up difficulty, and we'll be right back at ground zero again. Pointless.



Anyways, I have now mined 140 XPM! (ON a single computer) Seems I'm quite lucky.

I agree. I always wanted to see a CPU-only (no GPU mining ever) coin..
I was hoping for YAC to be CPU-only, but then GPU miners started popping and Sad
