Code: // Check proof of work and compiled it again, now I get: Code: received block 240ba90dc2981bed8761 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 Both nBits and GetNextWorkRequired(pindexPrev, this) are static across different runs.

You looking at 6.4.5 code.. 6.4.7 is (5 * 24 * 60 * 60) / 8 Oh right, so you've addressed that already together with the sync issue (or it was actually causing it). Now I'm seeing it: https://github.com/phenixcoin/Phenixcoin/commit/075d96d75873007d3d8997204cfaa2f3bf7507c2 I was only looking at the most recent commit earlier: https://github.com/phenixcoin/Phenixcoin/commit/48e6768f2bae47df679244108962fb67b1b89809 But actually I think this introduces an even more severe bug because now it affects the future blockchain instead of just the verification of the existing chain prior to the difficulty protocol change. Look at the current code in the repo https://github.com/phenixcoin/Phenixcoin/blob/master/src/main.cpp: Code: 840 static const int64 nTargetTimespan = (5 * 24 * 60 * 60) / 8; // Phenixcoin: 2.5 days Apart from the comment still not matching the code: (5 * 24 * 60 * 60) / 8 == (5/8) * (24 * 60 * 60) == 0.625 * (24 * 60 * 60) == 0.625 days the far more serious issue is that now the nInterval isn't 480 anymore if fNewDifficultyProtocol is true, that is if we are past block 46500 where the difficulty protocol adjustment applies. Now it's basically the other way around, for the old protocol we do correctly get: Code: nInterval = (((5 * 24 * 60 * 60) / 8) * 4) / (1.5 * 60) = 2400 which is the number of blocks until difficulty retarget as specified in the original forum announcement and on phenixcoin.com, and which in part explains why the block verification during the wallet sync doesn't fail anymore for retarget blocks which caused the sync to get stuck. But now for the new protocol we get: Code: nInterval = ((5 * 24 * 60 * 60) / 8) / (1.5 * 60) = 600 which isn't the 480 blocks as defined in the recent difficulty protocol fix! I guess this should be fixed urgently before the next difficulty retarget occurs And I still think this would fully fix it: Code: 840 static const int64 nTargetTimespan = 0.5 * 24 * 60 * 60; // Phenixcoin: 12 hours Title: Re: [ANN] New Client for PhenixCoin PXC ** PLEASE UPDATE YOUR CLIENTS ** Post by: MaGNeT on June 19, 2013, 10:15:48 PM that was not the old protocal ... the old was 2.5 * 24 Yes that is my point, currently the code does: 0.5 * (24 * 60 * 60) * 4 == 2.0 * (24 * 60 * 60) but shouldn't it be: 0.5 * (24 * 60 * 60) * 5 == 2.5 * (24 * 60 * 60) ?

Now I'm seeing it: https://github.com/phenixcoin/Phenixcoin/commit/075d96d75873007d3d8997204cfaa2f3bf7507c2 I was only looking at the most recent commit earlier: https://github.com/phenixcoin/Phenixcoin/commit/48e6768f2bae47df679244108962fb67b1b89809 But actually I think this introduces an even more severe bug because now it affects the future blockchain instead of just the verification of the existing chain prior to the difficulty protocol change. Look at the current code in the repo https://github.com/phenixcoin/Phenixcoin/blob/master/src/main.cpp: Code: 840 static const int64 nTargetTimespan = (5 * 24 * 60 * 60) / 8; // Phenixcoin: 2.5 days Apart from the comment still not matching the code: (5 * 24 * 60 * 60) / 8 == (5/8) * (24 * 60 * 60) == 0.625 * (24 * 60 * 60) == 0.625 days the far more serious issue is that now the nInterval isn't 480 anymore if fNewDifficultyProtocol is true, that is if we are past block 46500 where the difficulty protocol adjustment applies. Now it's basically the other way around, for the old protocol we do correctly get: Code: nInterval = (((5 * 24 * 60 * 60) / 8) * 4) / (1.5 * 60) = 2400 which is the number of blocks until difficulty retarget as specified in the original forum announcement and on phenixcoin.com, and which in part explains why the block verification during the wallet sync doesn't fail anymore for retarget blocks which caused the sync to get stuck. But now for the new protocol we get: Code: nInterval = ((5 * 24 * 60 * 60) / 8) / (1.5 * 60) = 600 which isn't the 480 blocks as defined in the recent difficulty protocol fix! I guess this should be fixed urgently before the next difficulty retarget occurs And I still think this would fully fix it: Code: 840 static const int64 nTargetTimespan = 0.5 * 24 * 60 * 60; // Phenixcoin: 12 hours Don't understand all you say but if it needs to be fixed, I guess it needs to be fixed ;D Iamatrix needs a twin-brother ;D Title: Re: [ANN] New Client for PhenixCoin PXC ** PLEASE UPDATE YOUR CLIENTS ** Post by: iamatrix on June 19, 2013, 10:29:06 PM Code: 840 static const int64 nTargetTimespan = 0.5 * 24 * 60 * 60; // Phenixcoin: 12 hours Yes, with the last update I made, it changed the diff change at 600 blocks instead of 480, and increased the time from 12hrs to 15hrs.. The 46500 marker came up way faster then I expected, I was thinking late thursday, early friday for the change over.. I will talk it over with John and see what we come up with.

Oh, so this was intentional :D I was assuming it must be a bug because it wasn't mentioned anywhere in the announcements or on phenixcoin.com I kinda like the "symmetry" between block reward halves every 840k blocks and difficulty changes every 480 blocks but by all means what's best for the coin! 8) Title: Re: [ANN] New Client for PhenixCoin PXC ** PLEASE UPDATE YOUR CLIENTS ** Post by: weav on June 19, 2013, 11:00:19 PM Just for general transparency, can you please explain why users of the binaries you guys provide were unaffected by the bug which just got fixed in the official code repository on https://github.com/phenixcoin/Phenixcoin ?
Apparently the issue only occured for linux users who compiled their own binaries from the public source, and noticeably so because the wallet sync got completely stuck. I cannot imagine a setting or environment where the former code wouldn't cause this behavior. Are you compiling the binaries you release on phenixcoin.com from a separate codebase which differs from the repo on github, and if so, why?

Thanks I was kind of wondering the same thing as well, I delete my block chain and it downloaded fine.. its not a different code base. Most people where not effected because they already had the block chain and it was stalling on a block with a diff change. trust me, I will be looking into why the windows binary worked.. its pretty easy to setup a mingw compile env for windows, grab the code for 6.4.5 and try it.. we have full transparency with the coin..

But normally this should not happen because litecoin clients should not be allowed to talk to phenixcoin clients. Each coin should use a different identifier (often called "magic number"), but pxc and most other coins did not change this identifier when copying the code base of litecoin (this identifier is 4 bytes, in the pchMessageStart variable) With a correct setting of this variable to something else (as long as it is not used by another coin), it would take at least someone manually copying the litecoin blockchain into pxc directory to have this problem.
