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 stop
3) 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!

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.

Nice work, thanks Sunny.

Works ok on win7 x64. Coin balance is correct, and solo mining works as expected.

Upgrade went smoothly on a Windows Server 2008R2.  Mining looks to be working but haven't found any blocks yet.

Thanks

I freshly built from github on OSX and get endless exceptions:
ProcessMessages(tx, 226 bytes) : Exception 'CDataStream::read() : end of data' caught, normally caused by a message being shorter than its stated length

As mentioned in a different post, I believe this is to be expected and will only cease after the protocol switch on the 10th.

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.

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.

Not if you use cookies or session tokens.

I've been mining at your pool for days now with the same username as here.
Still no verified balance.
Pretty sure my solo blocks didn't take this long to mature.
Any chance you could have a look at what is going on?

Thanks

It can take a few days for blocks to be verified.

I have been solo mining full speed for a couple-few days and as of now I have 111,789 PPC and only 8,975 have matured into a balance.

The PPC project in the beta stage, so as the coin matures and comes closer to the release stage, these issues should be taken care of.

Blocks take 520 confirmations to mature.

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 would suggest waiting at LEAST 6 confirmations as currently with PPC. I've noticed a few times where confirmation counts on my current transactions where bouncing back and forth on a 2-3 transaction/block orphan rate.
