Title: Lebowskis LBW -- Balance not matching transaction history. Why? Post by: btc4ever on October 11, 2013, 01:49:28 AM So I have been mining some LBW from time to time. Always solo mining. Never any send/receive transactions. Today I noticed that the reported balance is substantially lower than the sum of the "generate" transactions when I call listtransactions.
reported balance: 3822.56 sum of 'generate' transactions: 7509 ( I computed the sum of transactions by calling listtransactions '' 1000, then parsing the output into a CSV file and filtering out everything that is not category "generate", then summing. ) So this seems like a bug to me, but maybe there is another explanation? i did notice that at one point lebowskid was using a lot of CPU and the stake value became non-zero, and it was generating some transactions, which I thought was odd, but figured it was all part of the proof-of-stake logic. But now "stake" value is zero again, and the only two transactions types in history are "generate" and "orphan". A few more details below.

Why? Post by: aa on October 11, 2013, 03:57:23 AM I can only imagine that you mined a bunch of orphans when this coin was first released because I can't see it being possible to get orphans when you're the only person mining a dead shitcoin.
Title: Re: Lebowskis LBW -- Balance not matching transaction history. Why? Post by: btc4ever on October 11, 2013, 04:02:26 AM Ok, I wrote a little php script to make it easier to get the transaction totals by category. Script is below. I also tried it with 7 other altcoins both scrypt and sha256 based, all POW. All of them matched the balance correctly.
So I am thinking this is either a POW/POS thing I don't understand yet (likely), or else lebowskicoind has a pretty serious bug. Can someone with PPCoin or some other POW/POS coins please try my script below and report your findings? thanks.

Post by: btc4ever on October 11, 2013, 04:05:39 AM But the orphans should be detected as not on longest chain and marked orphan, no?
I restarted the daemon with -rescan just in case, but it still gives the same balance as before.

Title: Re: Lebowskis LBW -- Balance not matching transaction history. Why? Post by: aa on October 11, 2013, 04:07:30 AM You're mining a coin that's been forking its chain for who knows how long. You probably mined a bunch of coins on the 'wrong' chain.
Update your client, if you haven't already, and forget about the inconsistencies. Title: Re: Lebowskis LBW -- Balance not matching transaction history. Why? Post by: btc4ever on October 11, 2013, 06:06:54 AM The client is updated from github and freshly compiled as of a day or two ago and is fully caught up with the blockchain. Presently has 3 peers.
dead coin or not, "wrong" chain or not, I do not see why there should be an inconsistency between the balance and the generated transactions. As I understand it, if I was on a bogus chain and rejoin the longer correct chain, then a re-org should take place and the transactions from the wrong chain should become orphans at that point. Clearly this did not happen. Which makes me wonder: is there a bug in the reorg code? somewhere else? Or is my understanding of how this should work incorrect / incomplete?
