[MaGNeT]

I have a qt wallet for my Mac downloaded from here. Do i need to do anything? Looks like u guys are doing great work. Happy to beinvested in this coin :-)

no you will have to update.. unfortunately I do not have access to MAC or I would compile it.

Maybe you could PM maxpower?

https://bitcointalk.org/index.php?topic=216672.0

Done.... thanks...

Should I move my coin to an exchange until my wallet can get updated? How much time do I have, no idea what block we are on...

If you have a backup of your wallet.dat you're fine Don't panic

Works great thanks!

Do you guys intend fixing the syncing bug in the Linux version?

[iamatrix]

Do you guys intend fixing the syncing bug in the Linux version?

Yes.. I am trying to duplicate your issue, have not been able to duplicate it yet. I have it compiled on Ubuntu and CentOs with no issues..

Oh, weird, thanks for looking into it. Is there any debug info I could gather and send you?

[iamatrix]

Thanks to maxpower !!

The MAC client is ready...

You can find it here.

I guess I found the relevant error in the output of ./phenixcoin-qt -printtoconsole>

Code:

received block 240ba90dc2981bed8761
ERROR: AcceptBlock() : incorrect proof of work
ERROR: ProcessBlock() : AcceptBlock FAILED

Note that block 240ba90dc2981bed8761 is indeed block 2400, the block where sync gets stuck an the old difficulty retarget: http://explorer.phenixcoin.com/block/240ba90dc2981bed8761cc88977843f677f07cc12811cbb8bee981c843058c73

I am looking at this right now..

[weav]

I added some debug output in src/main.cpp:

Code:

    // Check proof of work
    if (nBits != GetNextWorkRequired(pindexPrev, this)) {
        printf("pindexPrev: %u\n", pindexPrev);
        printf("nBits: %u\n", nBits);
        printf("GetNextWorkRequired(pindexPrev, this): %u\n", GetNextWorkRequired(pindexPrev, this));
        return DoS(100, error("AcceptBlock() : incorrect proof of work"));
    }

and compiled it again, now I get:

Code:

received block 240ba90dc2981bed8761
pindexPrev: 40149344
nBits: 504365055
GetNextWorkRequired(pindexPrev, this): 504365040
ERROR: AcceptBlock() : incorrect proof of work
ERROR: ProcessBlock() : AcceptBlock FAILED

EDIT: not sure if relevant but after running it several times I noticed the value of pindexPrev (the "prev block index" according to the comments, sounds pretty static to me considering that my wallet is stuck at block 2400) seems to vary randomly:

Code:

pindexPrev: 44792240
..
pindexPrev: 29553056
..
pindexPrev: 41622112
..
pindexPrev: 51966576
..
pindexPrev: 41933584

Both nBits and GetNextWorkRequired(pindexPrev, this) are static across different runs.

I found the issues... switching to version 6.4.7

Please clone the repo https://github.com/phenixcoin/Phenixcoin.git

I will compile the binaries now.

Nobody is perfect

Great! That fixed it, wallet syncing properly now!  

While trying to debug the issue on my system I found another apparent dissonance in the code in src/main.cpp:

Code:

840 static const int64 nTargetTimespan = 0.5 * 24 * 60 * 60; // Phenixcoin: 2.5 days
841 static const int64 nTargetSpacing = 1.5 * 60; // Phenixcoin: 1.5 minutes
..
889 int64 nTargetTimespanCurrent = fNewDifficultyProtocol? nTargetTimespan : (nTargetTimespan*4);
890 int64 nInterval = nTargetTimespanCurrent / nTargetSpacing;

Ignoring the comments (which don't fully match the code and are possibly just leftovers from the feathercoin repo or something) and assuming nInterval denotes the number of blocks until difficulty retarget we correctly get:

Code:

nInterval = (0.5 * 24 * 60 * 60) / (1.5 * 60) = 480 

which is the number of blocks for the new difficulty protocol, but for the old protocol we get:

Code:

nInterval = ((0.5 * 24 * 60 * 60) * 4) / (1.5 * 60) = 1920

which isn't the 2400 blocks as specified in the original forum announcement and on phenixcoin.com...  

(it would be for int64 nTargetTimespanCurrent = fNewDifficultyProtocol? nTargetTimespan : (nTargetTimespan*5);)

Am I missing something?

Updated client on my pool.

http://pxc.coinmine.pl

Pool has proportional payout system so you will get instant payouts after each block - start mining!

is your pool still up?

that was not the old protocal ... the old was 2.5 * 24
