Anything stopping ppcoin from being merge-mined ?
September 26, 2012, 03:25:45 PM
Is there anything about the ppcoin protocol that will prevent bitcoin ASIC's from mining it? If there is, I'd see ppc as a legit alternate mining market where non ASIC tech could potentially thrive.

I have updated FAQ section on checkpointing:
There is still some alter coin designer throwing FUD out there to claim that our design is not a proper proof-of-stake design and is based on centralized checkpointing. So I would like to repeat here that central checkpointing now only serves as bootstrapping safeguard, not a permanent part of the protocol.
As to Rosenfeld/Cunicula's proof-of-stake proposals on Bitcoin wiki, they are competing proof-of-stake designs but not necessarily better than ppcoin. The design goals are different. PPCoin is designed to demonstrate that a future energy efficient block chain is possible, i.e. solving the energy consumption issue of cryptocurrency. This is a very hard problem to solve and in my opinion would be an important step forward for future cryptocurrency technology. Also we came up with ppcoin design probably around or before when Rosenfeld/Cunicula did theirs (we started design work in October 2011), not to mention their designs today are still somewhat proof-of-concept and may or may not be ready for any implementation.
From my point of view I am all for competing in free market fairly and friendly, and all the different alter currencies should treat each other part of a larger team to further advance cryptocurrency technology and maybe even a higher cause for humanity. That's why we choose to continue the tradition of Nakamoto and release ppcoin in MIT license and open for everyone to fork, experiment and compete. For me I am committed to continue work on and watch ppcoin network operations and see ppcoin fulfill its promises.
Thank you all for your kind support!
(Correction: As cunicula points out below, he and Meni Rosenfeld started their designs as early as July 2011 so about three months earlier than ppcoin design)

Why do you need central checkpointing?
As of our v0.2 centrally broadcasted checkpointing is no longer a critical part of the protocol. It's main purpose now is to defend the network during the initial growth period and help ensure a smooth upgrade path if critical vulnerability is found. We are confident that central checkpointing can now be gradually weakened and eventually removed to achieve similar decentralization level of Bitcoin as the ppcoin network matures.

When will we see PPC on the BTC-e exchange?
September 26, 2012, 04:28:56 AM
SOLVED 
I have solved the "unknown address" bug in the PPC explorer and the new version has been uploaded to the server.
I am going to start my own thread for the PPC explorer website now, further details will be posted there.

I would like to get explained what value represent "Coin day"
I had 400 as a stake and it disapeared, Will all my balance / newmint become stake after > 30 days ?
I had 400 as a stake and it disapeared, Will all my balance / newmint become stake after > 30 days ?
Coin-day comes from the concept of coin age as the amount of currency holding times the length of the holding period. If you hold 1000 coins for 30 days you have 30000 coin-days of coin age accumulated on these coins.
Stake does not 'disappear', as it simply returns to balance when stake matures (after 520 blocks). There is a small chance that all or a large part of your balance turns into stake (although usually it generates stake gradually) so we provided a 'reservebalance' configuration to keep part of your balance for immediate use.
newmint cannot transfer to stake as it first needs to mature into balance.
I am not totally sure how the display of "stake" related to balance and new mint is interconnected. I have been mostly looking at script sigs and hashes, so perhaps somebody else will chime in with a better explanation of how the fields in the getinfo output interrelate.
Relation between balance/newmint/stake
newmint --> balance (newmint matures into balance)
balance <--> stake (balance transfers into stake and then matures back into balance)

I believe "Coin days" used to be listed in the getinfo, but I am not 100 % certain.
I have been looking through the source code so much lately and "coin days" is how age is referred to so that is how I think of it.
For example:
" ppcoin: total coin age spent in transaction, in the unit of coin-days.
// Only those coins meeting minimum age requirement counts. As those
// transactions not in main chain are not currently indexed so we
// might not find out about their coin age. Older transactions are
// guaranteed to be in main chain by sync-checkpoint. This rule is
// introduced to help nodes establish a consistent view of the coin
// age (trust score) of competing branches."
Essentially a coin day is equal to 1 PPC that is unspent for 1 day.
From the Wikki: (https://github.com/ppcoin/ppcoin/wiki/FAQ)
When can I start generating proof-of-stake blocks?
After 30 days the network would start seeing proof-of-stake blocks. If you have balance ppcoind would automatically try to generate stake for you. If you find a stake the reward is 1 cent per coin-year consumed (can be roughly understood as 1% interest annually). The reward amount is added to your stake amount and is shown together in the 'stake' field of getinfo output.
I am not totally sure how the display of "stake" related to balance and new mint is interconnected. I have been mostly looking at script sigs and hashes, so perhaps somebody else will chime in with a better explanation of how the fields in the getinfo output interrelate.

then even if you don't mine any more, just by having coins in your acount, stake blocks are appeared?
Yes, hence the theory behind the energy efficiency of PPC.
The idea that eventually there will be enough proof of stake blocks being generated, that proof of work blocks will not be necessary to keep the PPC network running.

i got a stake block today. i don't know what it is but i am huppy :p
i am mining solo. "stake" blocks are only available during solo?

Proof of stake blocks are based on the amount of "coin days" you have in a account. You do not need to "mine" in the conventional sense to get them. Just have coins 30+ days since the last time they were spent in your account. When you generate a proof of stake block, so many "coin days" are destroyed (not the coins themselves, you still have them to save, spend..whatever)
Mining in the conventional sense is what is called "Proof of work" blocks, you mine by solving a hash below a target value, hence "work".
Proof Of stake = "Mining" based on number of coins in account unspent for > 30 days. Coin days are used up to generate a block.
Proof of work = Mining using cpu/gpu to solve hashes and generate blocks.
Proof of Stake is what makes PPC unique as no other active coin uses it.

Is there some sort of roi calculator or a simple formula i could use to calculate how long it should take to find a block. I been running this solo for 2 days and did not find a thing. appreciate any math wizards out there giving me some hope 
thanks.
p.s. using about 1.3 g/h
Any bitcoin calculator should work. For example, putting your hashrate and the ppcoin difficulty into this one gives about 10 hours on average, or 1 day 6 hours to 95%. Are you sure you don't have immature blocks? They won't show up in your balance and take 520 blocks to mature. thanks.p.s. using about 1.3 g/h
yes i am sure i have not received anything i even get blank results with the ppcoind listtransactions i am using cgminer not sure what the problem is sigh i know the set-up works as i am able to pool mine with results and i get a connection to the ppcoind server so i guess i am unlucky
September 24, 2012, 02:29:49 PM
ok thank you for that rubberduckie, for some reason your simple 5 lined response worked. I now have a client and ive started mining with pheonix.
couple of issues:
1. should I use the same settings as bitcoin mining within my phoenix bat file? I cant seem to get device=1 to work, simply crashes when I put both in the instruction line. at the moment I use this:
phoenix -u
http://PQBv6xTcYb5ZTs2pRRxZSmjBYCxYmFSRJs:[email protected]:9942 -k phatk VECTORS fastloop BFI_INT -q 3 AGGRESSION=21 WORKSIZE=128 device=0
2. when mining it does not display my speed (kh) is there a reason for this... apparently I am doing 0 kh but submitting shares
3. when mining with ppcpool i am getting alot of no work idle errors, will adding a higher -q value help?
4. when do the ppc actually go to my wallet?

So what does difficulty 1 represent, a certain amount of coin-age you need?
proof-of-work difficulty 1 represents 4 billion (2**32) hashes.
proof-of-stake difficulty 1 represents 4 billion (2**32) coin-day-second, that is, if you have 1 million coin-day you can roughly expect a difficulty 1 block in 4000 seconds. Also note the coin-age calculation here requires the age to be over 30 days and capped at 90 days.

Which miner are you using? It has been reported and verified that cpuminer 2.x does not work with solo mining of ppcoin.
September 24, 2012, 09:07:48 AM
Are you sure you don't have immature blocks? They won't show up in your balance and take 520 blocks to mature.
However, they should show up in the raw list of transactions, available via "ppcoind listtransactions". Also note that the current block reward is much higher than 50
(I just realized my script shows them as regular transactions; I did not care to check the "immature" bit, since I've done most of my *coin mining via pools. I admit it's fun to solo mine for blocks again
