NEW POOL!!!

http://xnc.altcoins.pw/index.php

Fee - 1%
Pool - proportional
Pool Connection - Stratum - VarDiff

PM me for More INFO

This is caused by the multi-pools coming onto the chain.  There is only one or two that comes in, but when they do, they go way beyond 51% on the chain, and it totally screws the client up.  That's why all the rejects (among other things)...  The difficulty doesn't retarget right to account for such a huge swing, and so many blocks are mined that anyone else on the network (because hash power otherwise never clears 10MH/s for this coin unless the pool comes around) gets rejects.  The whole chain swings onto the pool and we can't control that. You can tell it's a big pool switching because when it leaves, about 2 hours later, XNC starts getting dumped on Cryptsy like mad...

I'm researching what I can do with the client to protect this...  But when we go from 10MHs to over 200 (and that 200 is concentrated on one - maybe two pools tops), there's more like a 95% attack against the chain.

In a nutshell, it boils down to the dev only being concerned with the premine and initial release of the coins - with no real concentration how to protect the chain on this one... 

Difficulty back to 0.2~ but net hashrate at 222MH/s!!!

It's strange now. In fact it happened several days ago:

Several days ago, the difficulty jumped from 0.26 to 0.05, then many invalid blocks were digged out. few hours later, the difficulty jumped from 0.05 to 0.21, then the digged blocks were valid.

Now it happens again, the difficulty has jumped from 0.21 to 0.05, and the digged blocks are invalid.

I can't understand why it is. Is it because the xencoin network has been attacked or is it because it's time to retarget the difficulty?

Network hashrate has jumped from 2MH/s to over 70MH/s 

Difficulty has changed - xnc.scryptlife.com got it right!

BlueCoinStock has added XenCoin!!
From just now, we are collecting market XNC/LTC!

Public market: http://bluecoinstock.com/public/market/18
Full mode Cryptsy: http://bluecoinstock.com/viewer/18/2/1

Anyone know why different pools say the difficulty change is coming at different times? For instance xencoinhasher says 433 blocks, tompool says 1424 blocks yet xnc.scryptlife.com says 143 blocks?

Scryptlife was right last time it changed a couple of days ago so it looks its coming soon...

Coins received!!!  Thanks 

Sent -- much appreciate the hash power

Is it doing the same thing as mine?  Not able to decide which chain it's working with or how many blocks it has?

I have been soloing now and then but the wallet has been acting up again

I knew if another miner showed up, we'd kick that 'block-rut' I was stuck in --   Gotta move some coin around, but will split them blocks with ya a little better on the side --

Yeah - the addnodes are there, although I haven't monitored the connection to see if one of them is what's throwing the client off.  It happens usually when solo mining against the client.  I usually have about 7 connections and if I solo mine against it, after a few hours, it just goes batshit and decides it's missing some 400k blocks (900k in chain, 400k to download) -- then it rights itself -- which leads me to believe there's a bad node somewhere sharing the wrong chain.

That was another thing added/changed in the client I was working on was using version enforcement to make sure 'wrong chains' were not picked up (that and code in a couple nodes for seeding) -- I"m going to get a block explorer running on one of my US servers and set see how it does as a seed node -- working on a .NET/SQL based explorer (just an experiment) and a .NET/SQL based client to feed it the blockchain.  LevelDB sucks under high loads and is not effecient in my opinion when the chains get big.  It needs something more scalable for if/when heavier services depend on the chain data (such as exchanges or other things)...  Same scalability can come with *nix work too, but I've got 20 years on MS servers, so development there is much faster for me when it comes to backend work.

(even if I did that much for the server side of things, there would always be a satoshi based client as a reference, etc... But the flat-files the client uses are horrible under load and when the chain gets big...)

*edited -- I type slower than I think sometimes...

My wallet always seems to behave itself! Although with only two network connections. Have you got all the addnodes listed a page or two back in this thread in your conf?

I really need to compile the changes I have to the wallet and test them out...  Really getting tired of it losing sync with the chain and thinking there's 900,000 blocks left to download...

My main miner comes and goes   It's in my main development machine, so if I get into something too GFx heavy, I shut it down sometimes - lol - but I'm back in there now - been stuck on a block for a while -- maybe we can kick one through and get it minting a couple again...  I had 4 in a row last night and no luck since then -

Can see you're there now so I've joined in 

FWIW - If my miners are up (wee as they are), they're on http://xnc.hasher.ca - I haven't mined much -- still waiting to see what the dev's supposed plans are for the coin - but if their idle, they'll connect up and start mining when I'm not working -- so if you are up there, we might score some blocks...  The youcrazy.me pool gets stuck all the time and stops updating/posting shares -- so I don't go there anymore -- it's just not stable... 

Most of the sites that list the coin have block counts stuck at either 266k or about 400k.  CoinChoose has the wrong block count.  I emailed them but it still hasn't updated...  The only working explorer I know of is at altexplorer -- I've got the blockchain imported into an SQL db currently working on a different explorer and a couple other things...  I develop mainly in MS land since I have licenses and experience for it - so depending on where the project goes determines how much more time I put into anything

I have crappy AT&T internet and there is a screwed up edge router between me and the xnc website (not that it's ever updated) - I have to view it through one of my servers in Virginia to even get it to load - so that's the first step in a takeover -- a working site with some actual content...  Still no github commits on the original client - so much for 'stuff in the works'...

If the total network hashrate isn't over 10MHs, you can effectively solomine the coin.  That's the number that's been the breaker on my client when solo mining.  I get just as many blocks that way as I do on a pool.  What's interesting is if there are like 5 or 6 known coin pools and if they're all empty, that's not a good thing...
