[groggin]

 i have abt 40k stuck in wallet. (ver. #1.2x) was trying to send mining spoiles to cold storage but whatever amt i try to send (smallest try was0.001) unit exceeds the size limit and i must pat tx fee. send remains unconfirmed
upgraded to 1.3 no problem, and v.1.3 installed in the cooler
still no go

I am running win 7 and it was working fine.

I will check again when I get home

This is not good really. Make a copy of your wallet.dat file if you did not do this before the client update (actually is a must thing to do when you do update).

Then open the command window (run the cmd.exe) then start the wallet from the command line with switch -salvagewallet:

Code:

"C:\path\to\the\grain\wallet\app\grain-qt" -salvagewallet

I hope that helps.

doing this now. will report back the results

any active giveaway ? im updated to 86008 block and nothing is there... ?!

bosian was not online since you posted in the giveaway thread, so i would say give him some time to send out the coins.

in the meantime I've sended you some of mine

so far so good


nice trick. thanks!

It is all working fine on win 7 here

what official nodes needed in the grain.conf for 1.3 wallet?

[bosian]

It's good to see that everyone is waiting for the returning of PoS block generations. I hope everything will be smooth when we pass through the switchover block at 92000 in a day or two (pretty sure it will, as it worked fine in my tests).

Now I want to give you an overview of the issues with PoW/PoS so we will have a realistic expectations on the PoS.

From my experiences and my observations of many other PoW/PoS coins, the PoW/PoS coins are far less stable than the PoW only coins. The commonly observed problems are:
(1). PoW gets jammed (happened to many coins). Many fixed the issue by forking a new blockchain (including GRA), some did not bother to fix (or dev vanished?), like ADT and COL are still in PoS only mode.
(2). PoS stopped, like what happened to Grain, this is due to the out of sequence in time stamps.
(3). Lots of PoS generation affecting PoW block generation.

The issue (3) can be an annoying one. According to current algorithm, the PoW block time can be extended up to 12X the normal time, if there are a lot PoS generated in-between. This is a normal behavior to maintain the overall block time. And we don't expect PoS always generate a lot all the time (it's controlled by its own diff adjusting). Another possible issue with a lot PoS generation is that it might affect PoW diff, and cause orphans (and I still need to check the code to see why - my understanding is that the two diffs are separated). I saw this issue occurred with Lucky7Coin end of last year, it caused a lot of issues in mining (virtually all the mining pools are stopped as 90% are orphans), and most blocks generated were PoS blocks, with some PoW in-between (the PoW generated time increased between 2X to 12X). The problem is gone now after the PoS generation subsides in Lucky7coin.

The Grain is based on Lucky7Coin code (mainly to use its superblock generation algorithm), which in turn based on Novacoin/PPCoin. We adjusted many parameters and hopefully the same issue will not occur here. We also have all the fixes from PoW/PoS (like the fix from Balthazar on self-forking). For now we still allow the max PoW generation block time be 12X the normal one if needed. We could change it to less multiples such as 3X used (fixed by a patch in) Novacoin codebase, so it could make the mining of PoW less disruptive.

Anyway, just want the community knows the status of PoW/PoS coin in general, and let's hope the Grain will work great

I don't have official nodes, it is not the initial launch. Any peers should work. Please use the peers posted in the thread (for example, by bee7).

Well, it does sound rather technical, but I'm glad Grain has an active dev who has an interest in maintaining his coin, so I will continue to show my support for Grain.

I'm going to have a wallet on a 24/7 server and send my coins periodically there. Unless I can somehow get the wallet running on my Rasberry Pi, it's not practical for me to have this PC running 24/7.

[Morticio]

Like this coin. Happy he survive over now. With all crap coin arround, it's easy to disapear!

It's not a big deal, indeed.
