Thanks to drakoin for making me announce this here.
You're welcome. I had noticed that bug in my mint wallet, too - and I was very happy it got fixed! As coins share code, others might face the same problem.

Thanks for announcing your solution here. Cooperation and synergy is so much more profitable for this whole scene than competition and destruction.

I'm poor. Please tip me here www.tiny.cc/drakointip for my ideas and my work

Hello everyone,

In Mint we had a bug that affects "getbalance accountname" RPC calls since PoS phase started. This was a bug only for wallet's account keeping functions -- overall balance of the wallet was always correct. A fix for the bug is available on GitHub. I think the same bug may be affecting other PoS coins. Thanks to drakoin for making me announce this here.

Let me explain you the problem;

There are 2 ways to calculate the balance in the wallet, one sums unspent TxOuts and gives a single balance, and the other tries to bind minted coins / received coins / sent coins with accounts. Normally, result of these 2 methods should exactly match. In our case, they didn't (and I suspect other PoS coins to have the same problem). This is similar to the bugs CryptoRush experienced with BC when keeping records of customer balances in wallet's account functionality (it may even be the same bug, I don't know).


This was my problem after some PoS minting:

Code:
00:20:17 listaccounts             --> Summing these don't match wallet's balance
00:20:17 {
"" : -9970744.49303600,
"account1" : 0.00000000,
"account2" : 17487916.06958000,
"account3" : 200000.00000000,
"account4" : 1250000.00000000,
"account5" : 5035.17977500,
"account6" : 4984.06119900,
"account7" : 3450.50390700,
"account8" : 88294.56108000
}
00:20:57 getbalance *
00:20:57 9068935.88250500             --> This is wrong, but consistent with listaccounts sum
00:21:12 getbalance '*'
00:21:12 9068935.88250500
00:21:00 getbalance
00:21:00 8428756.53745800             --> This is the correct wallet balance
00:21:02 getbalance ""
00:21:02 -9970744.49303600            --> This is wrong, but consistent with listaccounts

The patch can be obtained from the following github commit. Note that unfortunately it's committed together with another change that disables PoW. Only changes in wallet.h, wallet.cpp, rpcwallet.cpp, main.h are relevant.

https://github.com/mintcoinproject/mintcoin/commit/dad79713d4172a569238de1b736abfbf307acfbd

Still, even with this patch, I wouldn't trust wallet's per-account functions to keep customers' finance information (there are more information that should be given in PoS wallets' RPC calls for proper bookkeeping, such as listing of per account stakes, mature/immature coins, etc), but I believe this is a step in the right direction. I will be very happy to receive some feedback about the patch and if it affects other PoS coins.


These are the testing steps to see if another PoS coin is affected :
This bug fix of  "getbalance accountname" might be interesting for other PoS coins:

Interested because long term Peercoin has one of the best looking charts. I think some of the new hybrids could end up following a chart like that, and if so, they have not reached "take-off" point yet. Anyway, my favorites are MINT/BC/ECC, precisely because miners can't dump them and crash the value constantly. Eventually enough people should horde and value go up, rather than just drop constantly like we see with almost every new LTC clone.

I also don't think billions or millions or hundreds of thousands matters at all. Just the interest and how many new coins (as an overall percentage) can flood the market.

I have some questions and thoughts on the matter. First of all, there seems to be older ones that are POW/POS the entire time, this is nice that they can always be mined and great to keep miners involved. That does add the complexity for value dropping long term with increasing mining power and difficulty not matching it. (ASICs) For example, I love PHS, but it can be mined and with a high interest, so generally appears to be losing value faster than it generates coins.

MINTcoin, is that the first one with the limited POW and then POS phase? Then ZEITcoin cloned it, and then Blackcoin came out right away - with a low interest rate and super short POW phase. This allowed it to beat MINT to the POS period even though it was released later. (ECCcoin is out now and overall I think has some improvements to the MINT design)

My questions (seems difficult to find this information anywhere)

#1 Is MINT the first limited POW/POS hybrid, and were all the others previously always POW/POS combined. If true, that makes it sort of unique, if you love or hate the idea, it does seem to be getting a lot of clones fast. ZEIT/BC/ECC/EDGECOIN-although likely a scam... others?

#2 BC ending POW has rarity by miners not dumping it, with indirect mining tech putting buying pressure, even with the low interest rate this seems more likely to gain value than a POW/POS minable coin, especially when ASICs start hitting them and miners dumping. So isn't the limited POW actually a MASSIVE advantage for a coin, rather than a disadvantage? Thinking long term, mass adoption, easier to have a wallet than a bunch of 280x cards or Gridseeds. More appealing to the consumer market later, I think?

#3 Don't limited POW coins have an advantage by being ASIC invincible after the POW phase?

#4 Are POW/POS coins in the POW phase immune to 51% attacks unless someone has over 51% of the stake? Heard yes and no...?

when you bring your wallet online with high coin age coins, you stand a better chance of staking than coins on the network with lower coin age

Can high coin age coins stake in as little as half an hour?

i've had coins stake in less than 30mins after opening (and unlocking) my wallet yes

Great thread & info, thanks!

I've taken the plunge and bought some POS coins, but now I'm unsure how to guarantee I earn my 'interest' for different coins. Do all of the POS coins require keeping the wallet open 24/7?

It would be great if you could add some info on what is required to generate the POS coins for each coin on your list.

I've done some preliminary reading today and it seems with some coins you might be able to risk opening the wallet as little as once a week and still get your stake coins paid, but I've also read conflicting reports that suggest nearly all POS wallet needs to be 'unlocked' and opened all the time to generate interest. I'm not sure how to 'unlock' a wallet, but suspect it might be the same as 'encrypt' a wallet.

This information is critical for any would be stakehunters, so it would be good to add that info in this thread.

Thanks again for starting a very informative discussion!

in short, encrypted wallet needs to be unlocked before you can stake
(if you don't encrypt your wallet, coins will also stake - NOT recommended)

to unlock encrypted wallet execute the following command in debug window
walletpassphrase mypassword 999999

it is NOT required to have your wallet open and unlocked 24/7 to stake

coins age with your wallet offline
when you bring your wallet online with high coin age coins, you stand a better chance of staking than coins on the network with lower coin age

for more info refer to

Thanks for taking the time to explain this.

Thanks
