ERROR: BitcoinMiner : proof-of-work not meeting target
This means a block was rejected. Could you post log output around this particular error? |

Yeah, that probably is why I'm not seeing the yay! ...
I also noticed that the official linux distribution compiles a different version string than it is shipped with in the bin directory!
"version" : "v0.2.0.0-g09051bd-beta",
vs.
"version" : "v0.2.0.0-beta",
I always compile from source. Somethings wrong there.
I'm gonna try on ppcoin 0.1.0 for a bit too, see how that goes.
If you build with make yourself, the version would look like that so it's normal. Here g09051bd refers to the git commit id which is the correct commit id for v0.2.0. The official build version string is v0.2.0ppc-beta. As to your cpuminer issues I don't know if it's just pure bad luck or something else. One suggestion is to look through debug.log and search for 'ERROR'. If you see messages about rejection of blocks you can post it here for analysis (although I suppose cpuminer should report block rejection in some fashion as well?). |

hi, I was wondering, why is there no exchange for ppcoin. anyway, for I project I am working on, I compiled the newest 0.2.0 beta and the exchange is here: http://exchange.zapto.org/ccexchange/1-4best mugen Congratulations to mugen and CryptoCoin Exchange being the first to start trading ppcoin  |

I have been attempting to write (yet another  ) GUI wallet for PPcoin. 1. Is there any way to rename accounts? The original null string account is horrid for coding, but I just cannot find a way to rename it or any of the accounts. 2. How does the daemon decide where the "newmint" coins that matured go? Do they always go into the null string account? Can that be changed? My apologizes if this information is already posted, but the account naming in this daemon appears quite different than those in the BTC/LTC clients. After Edit: If I use a set account (pp address)(account) for an existing pp address, it appears the PP address just disappears and the daemon just creates a new account with a new PP address and the old account gets a new PP address?? Where does the specified pp address go? I don't think things related to accounts have been changed from Bitcoin. I don't use this feature so it's not well tested. If you do observe different behavior from bitcoind please report it in detail here so I'll look into it. Best Regards, |

Mail server isn't setup yet.
I just updated the ppcoind, and that seems to fixed the site issue. I'm not sure why the update would have broken it in the first place.
Once the alert was sent all 0.1.0 daemons entered safe mode. You should be able to mine as normal in safe mode, just not sendtoaddress. Not sure if pool software has other issues with safe mode though. |

Weekly Update #2- The second week has passed for the ppcoin network, while we celebrated the release of v0.2.0. This release is an important milestone for the ppcoin project. I believe it is also an important milestone for crypto-currency technology in general, as energy efficiency has finally been solved without sacrificing decentralization. This would allow future crypto-currencies to be not only competitive in terms of decentralization and robustness, but also in terms of cost against established (centralized) payment services. Of course ppcoin is still in its very early days in the market so time would tell if my observation is right.
- Two protocol changes were included in v0.2.0 release. One is that competing block chains are now scored based on proof-of-stake difficulty. Sharp readers would note this is the counterpart of Satoshi's original scoring based on (proof-of-work) difficulty. The property of this formula is that it makes the threshold of effective double-spending attack very high, to the point of almost controlling the entire main chain. The other change is we have limited coin age weighting in proof-of-stake block generation to a max age of 90 days. This change defends against a patient attacker accumulating coin age indefinitely over the rest of the network. With this change the required threshold of stake to control main chain is raised significantly for a patient attacker.
- I have been asked whether I have plan to operate an exchange. The answer is no. It is noted that this week we saw quite a few people on the forum looking to exchange ppcoin with bitcoin. Several members of our community have hinted at plans of creating exchanges as well. But for me I am fully aware of my responsibilities to the network so I will not be involved in any exchange. My first goal is to ensure ppcoin network operates as designed to survive its first 3 months on the market. I would not allow any distraction to impact my ability to execute this goal.
- In the new release there are some minor improvements for getblock and getinfo. You can now see the total network money supply via getinfo. For getblock you can now see the mint amount for the block, as well as an additional option to see details of all transactions in the block.

Yes the genesis block minted 0 coins, as we said ppcoin had no premine and we meant it had absolutely zero premine. - As of block 3212 (2012-09-02 02:56:47 UTC) total network money supply has surpassed 5 million coins.
Happy mining and next week!

Is this true?
520 confirmation?
Bitcoin atleast needs 6 confirmation & that too called very slow.
Seems ppcoin wont be used in anywhere, coz it will take years to get confirmation alone.
520-block maturity only applies to block minting. For Bitcoin this parameter is 120-block maturity. As for user transactions how many confirmations you wait is entirely up to you and market concensus. Generally speaking the larger amount you send/receive the more confirmations you should consider waiting. Currently the network is protected by central checkpointing so transactions are pretty safe. In the future it would be decentralized and work similarly to Bitcoin. |

I let my 2 5830's mine PPC for over 8 hours and there's nothing in my wallet. This seems like a long time to go without getting any reward. Suggestions?
This is quite normal unless you see something about block being rejected in your miner. If you don't have the patience to wait you can consider joining pool. Give it one more day see if luck is on your side. |

I've looked around and I just want to clear up one idea about this coin:
If I have more coins, am I more likely to mine coins?
Like if I have 2000 coins and 1.5GH/s, am I more likely to mine a coin than someone who has 1000 coins and 1.5GH/s? And less than someone with 10000 coins and 1.5GH/s?
Edit: that is in 3 weeks huh?
No. What you describe is something close to cunicula's proposal (we have thought about a similar variant during our early design phase last year). In our design proof-of-work and proof-of-stake is separate and do not mix with each other. You have the same chance of mining proof-of-work blocks as the other miner with 1.5GH/s. But with 2000 coins you would have better chance of minting a proof-of-stake block than the other minter with 1000 coins, and less chance than another minter with 10000 coins. |

I have an idea, and am not sure why I didn't think of it.
I'm going to make a web-wallet that lets you put in your remote RPC. This will let you control your wallet remotely.
I will create a LIVE SHA256 of the site + tarball'ed SHA256 so you know I'm not saving your information.
This...will be coded one day. I've got a lot of people trying to contact me at once. Which explains why the pool's site has been jacked up for the past few days. >.>
Not sure I follow you. Don't you need to save user rpc username and password in a database? Sounds dangerous to me. |

I don't see anything in the link somehow. Do you still have trouble with balance? If so please describe in detail how did you upgrade and what you see in getinfo and listtransactions. |
|
|

Does this include the bugfixes luke-jr merged into his copy?
-MarkM-
No. 0.2.0 is still based on Bitcoin v0.6.3. Besides qt gui is not supported yet. |
|
|
|
|
Please note after 0.2.0 upgrade you may still see the exception message about tx messages in debug log. This problem is expected to go away after the network protocol switch on September 10th.

Official release build is now available http://www.ppcoin.org/ (via sourceforge) What's in 0.2.0 release: - Network protocol upgrade to fix the exception message in debug log (protocol switch Sep. 10)
- Main chain protocol and block generation protocol upgrade to improve security
- Allow multiple outputs in coinbase and coinstake special transactions
- Track mint (getblock) and moneysupply (getinfo) figures
- Public testnet is now up and running
The protocol upgrades are an important step forward for ppcoin. In my opinion v0.2.0 has now achieved most design goals of ppcoin project. Now we are reasonably confident that central checkpointing can be weakened gradually and eventually removed thus achieving similar decentralization level of Bitcoin. We plan to review our checkpointing policy on a monthly basis from now on. Upgrade instructions: Upgrade is required before Monday September 10th. Nodes that have not upgraded before this deadline will be disconnected from the main ppcoin network. To upgrade: 1) Before upgrade, you must first backup your wallet: ppcoind backupwallet <destination_backup_wallet_name>2) Shutdown ppcoin ppcoind stop3) Inside your wallet directory, remove all files and subdirectories except for leaving wallet.dat and ppcoin.conf in place. 4) Download 0.2.0 and unpack/install. 5) Start up ppcoind normally. 6) Use getinfo to confirm your ppcoind version is now 'v0.2.0ppc-beta' 7) You should see block chain is being downloaded again. Please note during redownload of block chain your balance will be shown initially as 0 and grow as block chain is being downloaded. This is expected. When block chain download completes your balance should return to the same value before the upgrade. Cheers and happy mining! |

Yes. With competition I didn't want to imply opposition. Competition is good, because it keeps the developers on their toes. If ppcoin and bitcoin are both viable, they surely will coexist.
Thanks. We also hope that our work on ppcoin could in the future provide healthy competition in the field of crypto-currency and help further advance this new peer-to-peer technology |

Is v0.2 merged mining capable ??
Unlikely. The developer makes a point of ppcoin being a competitor, thus not relying on infrastructure for bitcoin. Merge-mining will not be supported. The main benefit of merge-mining is to help a new crypto-currency to withstand 51% attack by leveraging the power of Bitcoin. This function is currently provided via our central checkpoint and will be provided by proof-of-stake protection in the future. So I don't see much benefit in supporting merge-mining. As to competition to Bitcoin I think it is still far too early to consider that. Our goal is to first validate the correctness of the design in the market, and possibly bring some fresh air of innovation into the community. Personally I have very high regard of Satoshi and the current Bitcoin development team. Even if we do manage to become successful and compete with Bitcoin I still consider we are part of a bigger team in the grand scheme of things and doors are open to all kinds of possible cooperations. |

I find this coin to be interesting to say the least. I have a stupid question, where do I get my wallet address ? I'm mining at NothinG's pool and want to add it to my profile. Thanks in advance.
To get address you can use ppcoind getaccountaddress ""
ppcoind getnewaddress
ppcoind validateaddressUnfortunately currently we are lacking in resource to fully support the qt gui version. So for now only daemon is officially built. Some of our users have attempted to build their own qt gui with some success. Thanks, |

How would I go about setting up my coins to do the "30 day stake"?
No need to set up anything. The stake minter is active always and will mint proof-of-stake blocks automatically for you. See our wiki FAQ for more explanations. |

To clarify, there will be no block chain restart for v0.2 release. All your wallet/coins remain valid.
v0.2 upgrade would require redownload of block chain though. This operation requires a backup of current wallet (ppcoind backupwallet <destination_backup_filename>), shutting down ppcoind and removing all files in wallet directory except for the wallet.dat and ppcoin.conf files. After upgrade all your coins and transactions should remain valid and just the same as before the upgrade.
As we promised before, we will do our best to avoid block chain restart. If severe flaws are discovered and such actions are considered, we would notify and consult with the community first. Generally speaking, if a block chain impacting issue is found and some existing blocks must be declared invalid, a partial block chain rollback is always preferred over full block chain restart to reduce damage to our users. But in any case, we will try to avoid these type of scenario to the best of our abilities.
Best Regards,

Fair enough. You sound like genuine now. I will definitely try to improve upon it if your concern proves to be valid.
Peace & Love
