What was the starting difficulty of PPC? Was it 1? Or 256?
I hope I do not regret answering what appears to be a non troll question from Smoothie:

Genesis Block was 1 Difficulty with 0 coins generated:

Do you?

I might, I might not.

But I am considering selling 1 or 2 silver eagle coins for PPC. I'm just doing my homework first.

I have done some work on the qt to allow gui users to properly see stake transactions. Total stake amount is also added to the overview page.

Expect v0.2.2 release next week to include this improvement. However there will be no official build support of qt-gui for v0.2.2 and users can self-build or acquire community released builds.

Sunny, are you working on anything to help protect stake signers against theft?

It is pretty important that people with large balances feel that the benefits of stake block generation (interest) exceed the costs (theft risk).

Not right now. I saw you made some good proposal in the other thread. I will be cautious about this so when I get some time I will evaluate different options.

I looked around a bit but did not find any information about the total network hashing power or speed.
http://www.proofofstake.com/ has some nice charts but no total network "speed" information.


While reading what I wrote, use the most friendliest and relaxing voice in your head.

Yes, that website is helpful. Since difficulty is adjusted continuously (rather than once every 2 weeks), network speed should be closely related to difficulty, even over short time intervals.

The variable of stake blocks generated gives the illusion of hash power applied to the network. The overall network speed in actual GH/s is much less than you would expect.

It is an interesting concept even though it is misleading.

Changes in difficulty are not misleading. The difficulty levels for PoW and PoS are completely separate. The graph only shows PoW difficulty, same as in bitcoin. When difficulty doubles, hashing power has doubled.

So then where is all that extra hashing power?

Both pools dont show it. So I guess it is a solo miner?

If you look at the block explorer you will see that there is much more PoS blocks than PoW blocks (recently). No way could the difficulty be going up because of more hashing power being added when there are hours between PoW blocks at times.

P.S. Last time I checked PoW difficulty is based upon how many blocks are found over time. If blocks are found less frequently wouldn't the difficulty go down? Obviously that is not the case given the current PPC PoW block generation.

I'm curious to your response to this to justify the increase in difficulty in PPC.

LOL

I dunno. PPCexplore is down currently. Based on the decrease in the mint rate, you are likely right that the hash rate spiked and then went down recently. Difficulty is an estimate of the current hash rate and adjusts much more quickly than in bitcoin. If the hash rate went down, then difficulty will follow.

Which has not been the case if you watch the two pools for PPC. Hash power has not increased 2.5 times yet difficulty has.

Smoothie's observation is correct, while proof-of-stake generation approaches 10 minute target, proof-of-work difficulty would increase and proof-of-work blocks become more sparse. This is because proof-of-work generation spacing target is designed to be variable between 10 minutes and 2 hours.

If you would like to compare hashing power to bitcoin network (10-minute fixed spacing target), typically a 3x multiplier can be roughly applied. That is, if I assume proof-of-stake generation now reached 10-minute spacing target, then I estimate that proof-of-work spacing target is around 30 minutes thus in terms of hashing power in the network it's equivalent to a bitcoin difficulty of 7000 out of the 21000 difficulty.

This means you cannot directly compare the difficulty to other networks for the purpose of total network hashing power. Given the same difficulty ppcoin network would run with much less hash power than bitcoin network.

After proof-of-stake generation stabilizes, an increase in proof-of-work difficulty would again reflect a proportional increase of network hashing rate.
