Vircurex reports network hashrate around 135 Ghashes.
As I have been discussing with Sunny King in PM because of all the variables in the design of PPCoin, everything changes each block, its next to impossible to calculate the real hash rate. I assure you its nowhere near 135 GH/s.
I can confirm that vircurex hash rate estimate is not accurate. However its not 'next to impossible' to estimate ppcoin network hash rate. I have already discussed this topic in my weekly update #12 last November:
- Regarding network hash rate, since ppcoin is designed with variable spacing target for proof-of-work blocks, you cannot directly compare network hash rate to other block chains based on proof-of-work difficulty. To estimate network hash rate you would need to first get an estimate of current proof-of-work spacing target (in seconds), by counting the number of proof-of-work blocks in the last 24 hours for example. The formula to calculate the total network hash rate is: hash rate = difficulty * 4G / spacing target.
Jorgeminator made a hash rate comparison between freicoin, terracoin and ppcoin, which I believe is reasonably accurate:
Here you go
It is also next to impossible to guarantee that for a given hashrate the coin will be at a certain difficulty within a certain period of time. Our PM discussions have made me think I should apply the PPCoin difficulty algorithm to Bitcoin and demonstrate what happens. I imagine Bitcoin's difficulty would be somewhere in the trillions (or worse) with the PPCoin difficulty adjustment algorithm.
Take calculations like the one done by Vircurex, which probably assumes a constant difficulty and a 10 minute block spacing, with a grain of salt.
Why do you want to apply a variable spacing design to a pure proof-of-work coin? There is no need for that. I was only recommending freicoin to adopt the continuous difficulty adjustment, not variable spacing target. Besides I have never claimed that a high difficulty means superior network protection, so why bother? But even if you do, ppcoin only makes proof-of-work difficulty between 0x - 11x larger so I don't know where you get this trillion number.
It's true that hash rate is a good indication of network strength for proof-of-work coins, but for ppcoin it's the contrary. A lower hash rate is preferred by ppcoin, as it's an indication of energy efficiency. Indeed even as a hybrid design, ppcoin is a lot more energy efficient to a pure proof-of-work coin of comparable market cap.
