Is the staking function fully 'fixed' now? The PoS block reward with the previous release was 0.00 GPL - when I tested it last!

I don't hear about this problem, but in previous 2.6 wallet my coins was staked normally.

Zipped blockchain does not work ;( (Win7 x64)

Code:

file unknown has LSN 276/5486018, past end of log at 1/28
Commonly caused by moving a database from one database environment
to another without clearing the database LSNs, or by removing all of
the log files from a database environment
__db_meta_setup: C:\Users\xxx\AppData\Roaming\GoldPressedLatinum\blkindex.dat: unexpected file type or format

As message says when you want to move indexed blockchain to other environment be sure to close wallet with daemonnamed stop true, which should detach database on close. It takes longer but leaves database in consistent state (no log files in database directory needed, as they are not portable between different env.)

However, provided zip is still usable for bootstrapping - one can delete blkindex.dat and rename blk0001.dat to bootstrap.dat.

Indeed. Confirming exact same issue with gpl.2016.03.09.zip on Windows 10.

However, the blockchain will sync. from scratch or import bootstrap as above.

Is GPL still the crypto with the longest stake interval?

* 365 days minimum stake interval

OK, my fault. Database not working without "database/log.00000001" file.

Database was reloaded: gpl.2016.03.10.zip

All fine with yours stake. Transaction Tab just not display staked amount. May be fix in next version.

Indeed. The staking process is successful. Just a display issue in the wallet Transaction Tab.

This coin is still marked as Failed on Crypto Database, are there any links such as websites, exchanges, blockchains, or mining pools?

Website and exchange soon. New GitHub source: https://github.com/scificrypto/Gold-Pressed-Latinum  (old was .../scificryptocoin/Gold-Pressed-Latinum)

New version GPL 2.7.2 Soon!

Change log:
- Remove old IRC code to prevent antivirus warning.
- Fixed Staked amounts showing.
- Fixed Russian translation.
- Updated checkpoints.

If you know any other bugs, post here before release.

Not sure if it's a bug and can be fixed, but... When I unlock my wallet for 'staking', the GUI is very unresponsive, click and wait all the time. CPU load hovering around 25-50%, this should not be the cause. I've noticed the same with other wallets (e.g. Cubits), but our precious GPL is for sure the toughest.

It is because of big number of small transactions in wallet. Try use reservebalance=xxx, where xxx is 90% of total balance.
I reduce this problem in KED, may be fix GPL too.

And don't use mining wallet for staking, every month send coins to another wallet by 50-150 GPL in one transaction.

Sounds like a plan, I'll give it a try. Thank you!

I fix wallet freezing when staking, but found another bug that can't fix:
All stake reward rounded to 0.05 GPL and on generated transactions 0.2 COIN you receive 0%
or must wait 5 years before start staking.

[Dunkelheit667]

Thanks for fixing the wallet freezing!

Well, the 0.2 coin bug explains why I've rarely seen coins staking in the past, the vast majority of my precious GPL were solo mined. They will in two years, good to know.

Here is another bug: getbalance gives weird numbers. Not sure, but listaccounts seems to be off as well. The total amount is wrong and distribution on my accounts/addresses looks incorrect. Hard to tell without block explorer atm.

[vampirus]

Problem with 0.0 reward fixed. Now parameter combinethreshold work correctly on all coin age.
