cent die... the people lost a lot of money..always lose

Hi,all, i want to take over Pennies project if no one care about it. Thanks shakezula and The_CatMan for creating it and fixing the stake issue.

I like Pennies because it's no decimal and pure POS. POS is first introduced in PPC, but PPC can still create valueable CPU-Mined coin, Pennies has enough coin now, CPU-Mining is valueless. Pennies must be better than many other coins if its code is stable and it has more feature.

I have done the following work:
1. Accelerate startup. Old Version startup cost 30 minutes at least in my laptop, new cost only 3 minutes at most. I found PrimeCoin startup runs much faster than Pennies, so i migrate the related code into Pennies.
2. Accelerate sync. Old Version can't sync normally. I'm not sure i have fixed the sync issue, but i has tried 10 times to sync correctly between 3 hour and 14 hours. but 10 times test is not enough, if you meet the sync issue, please let me know, i will try my best to fix it.
3. Support Bloom Filter Protocol, it means Pennies will support Light-Wallet soon, Android Wallet will be released later. I have finished a light wallet demo, it can finish sync in 20 minutes and can receive and send coin correctly.
4. Fix the issue:Stake-Mining cost 100% CPU.
5. Fix crash issue. Old Version startup will crash in my laptop because scrypt-hash has some CPU-specific code.
6. Upgrade openn-ssl to 1.0.1g


How to upgrade
1. Backup wallet.dat
2. remove the folder of %APPDATA%/Pennies
3. startup piggybank.exe
4. after synced, copy the wallet.dat to the folder of Pennies, restart piggybank.exe

Important Note:
The format of blkxxxx.dat and wallet.dat has changed for accelerating startup, please backup wallet.dat before running 10.3.1

[Rozu]

can you give me the last 10 lines of debug.log?


there are many new code added than before, i test only myself for  some days, maybe there are some new bug, i will fix it quickly.

do you feel startup much quicker than before?

or comparison's sake, using the GPU miner earlier in this thread, at this difficulty on 6 x 7950's (about 11Mh/s) I am getting about 12 pennies an hour on average.  I believe a single 4core sandy bridge is getting about 125Kh/s IIRC.

11Mh/s with 6 x 7950's ? :-)

Upgrade from 10.2.1
1. Backup wallet.dat

3. startup piggybank.exe
4. after synced, copy the wallet.dat to the folder of Pennies, restart piggybank.exe

Upgrade from 10.3.1
 just start the new client

Important Note
  10.3.1/2 is compatible with 10.2.1, it will not generate fork. if you don't want to re-sync, you can still use 10.2.1

Advantage of 10.3.2
  1.startup much faster than 10.2.1
  2.support light-wallet, will release light-wallet soon
  3.optimize syncing, if you can't finish syncing with 10.2.1, you can try 10.3.2
  4.10.2.1 will cost 100% CPU time when stake-minig, if you're using linux, when you type:./pennies getinfo, you will find the reponse will last several minutes, 10.3.2 fix it.
  5. if your startup will crash when using 10.2.1, you can use 10.3.2

hi,lucky1488
   CPU-Mining pennies is valueless, it just generate 1 coin one minute. If you want to do this, you just do the following:
    1.click the button of "Command Line Banking"
    2.select the tab of "Virtual Teller Window"
    3. type:mintpennies true

    You can buy pennies from others and get interest every 9 days. if you buy 1,000,000,000,  you will get interest of 900,000 every 9 days.
    pennies is very cheap currently

    if you can't finish syncing using 10.3.2, you can send me debug.log in the folder of Pennies, i will analyse the log and fix it if it's a bug.

help me? how you mine cent coin now?  My wallet cant synchro. all blocks.

Hi Rozu, sorry my English. I am newbie and dont understand where i can find debug.log and  now  i have 10.3.2 wallet and  over  3 hour  wallet stop at 6894 block

[Rozu]

hi, lucky1488, thanks for your report, debug.log is in the folder:
  C:\users\Rozu\AppData\Roaming\Pennies
  "C" is your system disk.
  "Rozu" replaced by your username

you can send the debug.log to my email:rozupennies@gmail.com

i will try to upload the newest data to somewhere then you can download it and finish syncing temporary

Dear Rozu,
When i run the pennies wallet, there will show the info:

"
Error reading wallet.dat , all keys read correctly, but transaction data or address book entries might be missing or incorrect.
"

and when i deposit few cent to this wallet, the wallet is running ok, but if i withdraw few cent from this wallet, there will show error info:

"
Runtime error!
program:
This application has requested the Runtime to terminate it in an unusual way.
Please contact the applicaion's support team for more information.
"

What is wrong with my pennies wallet? and how i can fix it?

many thanks.

hi, xchange, the following steps may works:
1.move your old wallet.dat to somewhere to backup
2.finish syncing
3.put your old wallet.dat into the folder of Pennies
4.restart piggybank.exe


the format of wallet has been changed since 10.3.1 for accelerating startup, but 10.3.1/2 will auto upgrade the wallet after synced.

Here is the another problem when i sent a few cent to another wallet:
Error: The transaction was rejected. This might happen if some of the coins in your wallet were already spent, such as if you used a copy of wallet.dat and coins were spent in the copy but not marked as spent here. (code -4)
