nice! is it possible to split the mint daily into proof-of-stake and proof-of-work? Yes, currently it's just PoW, will add another for PoS overlay at some point.  |

In ppcoin transaction fees are not redistributed to the miners, but instead "destroyed". This destruction is compensated by the influx of new money, either through POS or POW blocks. This is a drastic change of the incentive structure for validation nodes and may become a problem, as explained in the following:
In bitcoin, the transaction fee acts as an incentive for miners to include transactions. The first goal of transaction fees is to accomplish spam prevention. The second, more complex aspect is the incentive for validation nodes: By providing a transaction fee, a validation node can earn money by including the transaction in the next block. If the block gets crowded, the validation node can prioritize transactions based transaction fees. (However, that incentive structure posses its own problems, since nodes may have an incentive to WITHHOLD transactions with large fees from other nodes)
In contrast in ppcoin, there is no direct incentive to include transactions into blocks. Thus the mechanism to determine transaction priority may vary dramatically throughout validation nodes. A person creating a transaction has thus NO DIRECT MEANS to influence the priority of the transaction. This can become a problem if the transaction limit in ppcoin is reached.
This is a QOS (quality of service) problem for transactions in the ppcoin network. Users have to be able to increase the priority of their transactions by providing monetary incentive.
Would it not be possible, to, change so that a min tx of 1c is required (as opposed to fixed at this), and then 0.1/tx is destroyed? As such, allowing clients to still give a tx fee to the validating node, if they so desire, for priority? |

Added "minted daily", want to add "effective hash-cost per coin" on 2nd axis maybe later.

Considering this USD / PPC thing, given there's no exchange, would people be fine with it calculated as PPC:BTC * BTC:USD ?
Nice!! I believe your calculation is the only choice to get PPC/USD, so go for it! ok considering where to pull historical prices from, I guess MTGox. |

Aha I get that it's good, that there are many crypto currencies, so, IXCoin, I0Coin, BBQCoin, DevCoin, LTC all changed parameters, and people that endorse LTC seem to be back that ASIC will make GPU miners choose LTC as opposed to selling up or moving to ASICS?

In response to this post: https://bitcointalk.org/index.php?topic=81542.0 by PatrickHarnett which is was stickied in the "Long-term offers" section, a misnamed Ponzi-corner of this forum which contains nothing but scams. Well I was right about BCST and I'm going to be right about all these too. Here are a bunch of Ponzi Schemes, all are poorly executed and all follow the standard Ponzi 101 model of having a totally obscure business plan with a totally outrageous interest rate. I will be making spreadsheets for each scam showing why they cannot pay the outrageous rates. Ponzi Schemes & Similar ScamsHonorable Mention:Dank and his various, odd scams that even the guys that got rolled by Pirate wouldn't invest in |

Well maybe Sunny is coinhunter  I did wonder. I don't think this is something I will get involved with after all. Well, we may never know. And it doesn't matter. Judge ppcoin for the design it is - if there is a problem with the creator but the underlying design is good I suggest coming up with an alternative client. Same holds true for bitcoin. Right know sunny is doing a good job though as far as I can tell. +1 |

HOW MANY PPC DOES SUNNY KING HAVE? RIGHT YOU DON'T WANT TO KNOW! BUT I DO!
HOW MANY LTC DOES SMOOTHIE HAVE? RIGHT YOU DON'T WANT TO KNOW! BUT I DO! |

Hi
I know that LTC was originally created for CPU, but now, it's just like BTC - GPU miners make up most of the network and that the hashing function is different but what's the actual difference? Is it just a speculative currency?

Some charts I'd like to see... * difficulty over time * coins generated from proof-of-work blocks vs proof-of-stake blocks per day/hour/whatever For the charting, consider HighCharts: http://www.highcharts.com/Thanks for making these charts! I am using high charts, will be adding difficulty and volume next, but I like your other suggestion may well add this. I'll probably modify the client to hook the database. Just moved from SQLite into Postgres - so now I can finally write so more "useful" SQL / get nicer graphs. PPC Explorer has an API. The nethash call gives out some of the info you may need. www.ppcexplore.org:2750/chain/PPcoin/q/nethash/1/start -will give you the entire block chain. I cut a section out below. blockNumber: height of last block in interval + 1
time: block time in seconds since 0h00 1 Jan 1970 UTC
target: decimal target at blockNumber
avgTargetSinceLast: harmonic mean of target over interval
difficulty: difficulty at blockNumber
hashesToWin: expected number of hashes needed to solve a block at this difficulty
avgIntervalSinceLast: interval seconds divided by blocks
netHashPerSecond: estimated network hash rate over interval
Statistical values are approximate and differ slightly from http://blockexplorer.com/q/nethash.
/chain/CHAIN/q/nethash[/INTERVAL[/START[/STOP]]]
Default INTERVAL=144, START=0, STOP=infinity.
Negative values back from the last block.

The POS blocks are fairly easy to pull out, 6325 was the first POS with a difficulty of ~256 vs the ~13,000 of the blocks around it. One could probably use the logic that if a blocks difficulty is below a certain percentage compared with a number of blocks around it is POS. PPC explorer uses different logic to see POS blocks.One of my short term goals is to add a field in the database and flag blocks either as POS or POW. Perhaps I could replace the inaccurate net hash per second field in the API with a POS/POW flag (Probably a Boolean). Aha interesting I'll have a look into it. |

Some charts I'd like to see... * difficulty over time * coins generated from proof-of-work blocks vs proof-of-stake blocks per day/hour/whatever For the charting, consider HighCharts: http://www.highcharts.com/Thanks for making these charts! I am using high charts, will be adding difficulty and volume next, but I like your other suggestion may well add this. I'll probably modify the client to hook the database. Just moved from SQLite into Postgres - so now I can finally write so more "useful" SQL / get nicer graphs. |

I did not mean pull as in remove, pull in as far as make a copy for themselves, maybe in their wallet file. Any machine, aslong as you have your wallet keys, you could read your recent mail. The 1c/KB/message I think works fine. Most "messages" arnt much more than a few kb's. Obviously that could be changed in the future.
Just throwing out ideas.
Ah I see. Although the application software is meant to manage their own copies so these messages won't be stored in wallet. Yes as long as you have wallet keys you can always reconstruct a copy of your messages that have not been garbage collected. This can be done by the application via commands similar to getblock/gettransaction. I don't know if it's a good idea to reuse wallet keys for identity keys, or if there is requirements for wallet to store a different type of keys for identity. Well just an idea of what a good aux chain for PPC might also do if I get enough time I might setup a MailCoin, where by mining gives you more credits to use the system, or you can buy them, it's distributed and encrypted. |

Strange suggestion,
Would it be possible to build anonymous-messaging on top of an Aux Chain/Blocks?
Messages sent signed with keys, encrypted with known GPG keys; could set max lenth of X bytes, might be a nicer messaging system than say TorMail; also as they expire after X time, it would allow the "client" to if so the receipient wants, "pull" the message off of the chain.
I am sure it's possible, but keep in mind data are stored on block chain for a fee (1 cent per kilobyte/message). Also there is no way for the sender or receiver to 'pull' their messages from block chain, in fact any node can choose to not to garbage collect auxiliary blocks and keep them forever. But since the message is encrypted so maybe that's not a problem. I did not mean pull as in remove, pull in as far as make a copy for themselves, maybe in their wallet file.

Ltcdice.net gets a lot of traffic even after your complaining. We actually are so popular that someone decided to DoS us. And I'm sure it will get more traffic than this game. But as I have stated I'm all for compitition in a free market system. How's your phailphailcoin Dice game coming by the way? It's only got 5 bets today, 4 yesterday, and 0 the day prior, compared to hundreds a couple weeks ago. Maybe someones autobet script has stopped? |

PPC is emerging as a viable 3rd alternative too.
It has been around for what 4 weeks? Most people who started mining it had no clear idea how it worked. So many questions got answered after the fact. I don't believe it is viable given how it started. If you ask most about PPC they couldn't tell you how it works 100%. If you ask most people about stuff that's been around a short time, you're right, they probably wont know how it works. A lot of people understand litecoin, as it's just the same BTC, but with a different hashing algorithm - doesnt really bring anything new / worth learning; it's a very simple concept to learn. Maybe it's a good thing, that people, unlike all the other Alt chains, need to read up a little about PPC before they understand it. The white paper can be found at http://ppcoin.org/If you ask most about PPC they couldn't tell you how it works 100%.
We aren't sure yet that it actually does work 100% -MarkM- This reminds me of  So far PPC is to be working as outlined in the papers/specifications. I am not sure who "we" or "100%" refers to (maybe LTC community?). If you ask most about PPC they couldn't tell you how it works 100%.
We aren't sure yet that it actually does work 100% -MarkM- I heard something about 30 days etc you have to hold coins to have a "stake". I'm sorry but if they weren't willing to let people know ALL of the details before launching it or even when launching it, what's the point. It's only "fair" to those who know how it works. Otherwise you can't make smart moves in terms of trading or holding coins. Have you read the paper at all? http://ppcoin.org/static/ppcoin-paper.pdfA mint rate of 1 cent per coin-year consumed is chosen to
give rise to a low future inflation rate. PPC is emerging as a viable 3rd alternative too.
It's hard to take PPC as anything more than a pump-n-dump when the block reward has already dropped in half...twice. Do you understand why and how the block reward reduces, and how it is tied into difficulty? Unlike the other alt-crypto chains the goal of PPC is not to feed energy inefficient miners; or early adopting miners. It's the provide a stable, more energy efficient chain. Its also the first one to effectively implement Proof of Stake. _____________________ I am happy to consider LTC as an viable Alt Currency, as is PPC. PPC is different to LTC and BTC. What this thread suggests is that a lot of you LTC guys are very uninformed about PPC, and that it would be beneficial to read the white paper if you guys get a few minutes. |
