Labcoin,

Is TheSwede75 still part of the team?

Would also be interesting to see if they still consider me part of their team...

They're still listing howard and me here: http://labcoin.com/presentation.html
Despite promising to remove that ASAP. Not a good sign at all.

So, looks like we've now reached the point where he needs to delete more than half of the posts of this thread to remove all traces of those questions and the following shitstorm? Roll Eyes

-H.Z. Wang has verified to us that Labcoin never took receipt of his finished chip design.  Who's gear are you hashing with?  

- Someone else completed his work. We are hashing with our own gear.

"Completed". Aha. That implies that you actually got any results of his work, which he says you didn't. If you did, please also pay him appropriately. 10btc is a joke.

-Why has 65nm development been suspended?

- Resources are used according to priorities. Development will restart next week.

So who's going to do this? Are you still counting on me to do any work for you?

-Why do you refuse to properly identify (video skype) yourself?  Video chat with TheSeven right now.  Prove you are who you say you are.

- My identity will be proven upon a meeting with someone nominated as a community representative when we open our mining facility.

Why do you refuse to even tell people who's actually involved with the project, and what your real identity is?
That is something that you should really publish here ASAP.
Your answer suggests that you're just trying to buy more time before people figure out who you really are. (Alberto?)

-What's the fund address?  Show us the money.

- I need to shuffle funds located in different wallets  for which i don't have control now.

Whatever that means...

-We're down to 10TH now?!  What happened to 50?

- We are not down to 10 TH, this is the first batch total hashing power.

You previously said that you're going to deploy 20 TH/s by the 15th. That's now down to 3 TH/s in your previous announcement.


Also, I hereby publicly request that you take down any web site or shareholder information that mentions my name. I already asked you to do that privately weeks ago, but you just ignored it. Please remember that you never had my consent to abuse my name and reputation in such a way.

Looks like the transaction was finally mined by someone.
I'm not quite sure why, but things should be fine for now.
We just need to prevent this from happening again in the future.

PRIMECOIN NETWORK GETTING DDOS ATTACK?

I dropped 90% in PPS. (PC, and all servers)

See a few posts above: We know what's happening, and a fix is being worked on. For now everyone is affected by it to the same degree, so it isn't really much to worry about.
5  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency on: July 22, 2013, 09:48:30 PM
It is not an attack. It's an issue in the miner that doesn't handle large block efficiently. A fix is being tested. Both the stock miner and mikaelh's miner are impacted.

Looks like I "broke" Primecoin by accident. Oh crap.

Anything I can do to help fix this up? Might double spending the funds in smaller transactions help resolve this?
If so, what's the easiest way to do this, now that the offending TXNs are lingering around in my wallet?
Or can someone somehow just forcibly mine them to get rid of them?

Why aren't those TXNs being mined (but relayed) in the first place? I sent them with stock primecoind with stock fee settings. I feel like that really shouldn't happen...

How long are these going to float around in mempools if we don't do anything about it?

I assume things will temporarily fix themselves for now as soon as the last of these large transactions get encoded into the blockchain. And then soon there will probably be updated builds of primecoin that fix its handling of large transactions.

IIUC the problem is that these transactions aren't going to be mined into blocks if the miner runs an unmodified primecoind.
So these will be around for a while if we don't take care of them somehow :/

Voting is over. #199 wins the contest. Say hello to ppc's new logo! Now on to rebuilding the website!



Is that available in a vector graphic format?
This particular image looks like it was scaled down by just removing lines, really crappy.
Can you make a PNG image with alpha channel and without the background available in the highest possible resolution?

So I have about 35 coins which are now about 32 days old.  I have a few questions about coinstake minting.

Do my coins have 35*32 coin days or do 35*2 coin days?  In other words, does coin age only start building up after the 30 day waiting period?

My wallet is not encrypted, when I run the client, do I get any indication that the client is minting?  I would at least expect to see some CPU activity for the process, which I don't.

Once I do find a stake block, and after I wait the 520 block stake period, do I have to wait another 30 days before I can start trying for another block?

You have 35*2 coin days, and yes, you'll have to wait for another 30 days (at least) after mining a stake block. The probability to even find one within a year with such a small amount of funds is fairly small.

This seems odd as it would encourage people to wait the maximal amount before trying to mine a stake block, since every time you do, you lose 30 days of interest.  So under ideal conditions, the interest is not 1%, it is about 0.75% interest, and only if you can reliably mine your stake near the end of the 90 day cap period.

Any idea why my client does not appear to be stake mining? (CPU usage is zero)

Wait, there's a misconception here. It's 35*2 coin days for the purpose of difficulty, but 35*32 for the amount of interest calculation.

If you don't have many unspent txouts older than 30 days, the CPU usage will be fairly low. The whole point of proof of stake is that it reduces energy consumption by not being processing power bound, but rather time and money bound.

Those trying to use the linux build, although the .tar.gz is truncated, the extracted primecoin-qt is ok and runs fine.

But I need to run it headless!

-gen

That doesn't help at all, you can't run the QT one without an X server being installed on the box...

16  Alternate cryptocurrencies / Altcoin Discussion / Re: [PPC] How does POS work to confirm transaction if POW miner are all gone? on: July 07, 2013, 03:26:50 PM
In PPC, PoW and PoS are mostly independent, except for serving the same purpose (to confirm transactions).

If you look at http://theseven.bounceme.net/~theseven/pool/netstats, you see the dots in the two charts. Each dot is a block.
You can see that there is some amount of both, with the vast majority being PoS blocks these days. Both kinds confirm transactions.
If there wouldn't be any PoW blocks, nothing much would happen except for the upper chart being a flat line without any dots.
17  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] [PPC] PPCoin Released! - First Long-Term Energy-Efficient Crypto-Currency on: July 03, 2013, 05:47:15 AM


30 days is the minimum age for generating stake coins. They are not guaranteed to generate stake at 30 days, it might be 31, it might be 50, it might be 450000, but the older they are the more likely they will find PoS blocks.

Thanks. I thought the "Stake:" is for how many coins are eligible for generating stakes. There really should be a manual for the wallet, at least for the PPC specific features. I see similar request on ppcointalk http://www.ppcointalk.org/index.php?topic=27.0

Yes, there should be better documentation, but someone needs to write it Wink

The "Stake" value is how many of your coins are currently locked down because they generated a Proof of Stake block.
Coins eligible for the generation of such a block are generally any coins that haven't moved for 30 days, but beware that sending any transaction might pick arbitrary coins from your wallet, send part of them to the destination and part of them back to yourself as change, which counts as "moved" as well.
Another condition is of course that it will refuse to use funds to generate a stake block if that would drop your "movable" funds below the specified reserve amount.

hi - I wondered if there was an RPC to ppcoind, or a website somewhere, to allow me to determine the current proof of work block reward (i.e. right now it seems to be around 397).

Cheers,

Will

Call getmemorypool (or getblocktemplate with my patched ppcoind) and check the "coinbasevalue" field. That's the reward in "sunnys", i.e. 0.000001 PPC units.

Why that? Can you back up that claim? IMO ESMPPS is much more fair to miners in the long term.
ESMPPS is broken by design. Just like with original SMPPS, badluck could cause collapse of mining pool. RSMPPS is invulnerable to this scenario.

IMO ESMPPS is much more fair to miners in the long term.
Actually, RSMPPS and ESMPPS are the same in long term. But in fact, RSMPPS results are better.

P.S. You can see RSMPPS rounds list example here (switched to RSMPPS from SMPPS since round #112):
https://pool.itzod.ru/rounds

The main flaw of SMPPS is that in the long term, even with average luck, a queue of unpaid shares will build up, dropping immediate payout ratios for new shares to nearly zero. This is not true for ESMPPS though: While the immediate payout level will drop proportionally with long-term average luck, it will come back up when luck gets back to normal, unlike SMPPS.

While SMPPS gives priority to old shares and RSMPPS gives priority to new shares (both are a bad thing IMO), ESMPPS does neither of those by giving priority to the shares that have been paid the least so far, i.e. affected by luck the worst, until they catch up. This way it attempts to pay all shares equally in the long term.

The ESMPPS design is based on several weeks of discussions and hundreds of simulations, where it was directly compared to other reward distribution models on the very same luck data, and it turned out to behave more fairly in the vast majority of cases.

It is true that RSMPPS might provide more incentive to join a pool if you want to be paid quickly. That is not true if you're in for the long term though.And while it does have the same statistical average long term outcome, just like PPS, PPLNS and soloing have as well, it does have a much higher share-based variance than ESMPPS.
So while RSMPPS moves the SMPPS flaw from the newest shares to random shares, ESMPPS tries to spread it out evenly across all shares rather than picking individual ranges of shares to be basically just discarded. In fact I think that RSMPPS is more similar to PPLNS than to ESMPPS.

(Another problem with RSMPPS is a technical one: It requires you to keep track of an ever increasing number of individual shares.)

RSMPPS would be much better than ESMPPS.
