Still 0

Currently on block 11516

just run hash check again.

better yet, check my last post for updated checkpoint.cpp file.
https://bitcointalk.org/index.php?topic=557946.msg6558788#msg6558788


dump into src folder & recompile it. takes 15 secs, as it only needs to rebuild checkpoint.o

following IP caused this other fork, not sure who it belongs to.
37.187.241.168

Seems to be someone from France

So what's up with the forking? Minep.it sent me ~500 coins and I haven't received anything in my wallet

[trademark]

What's going on here? Difficulty was like 7-8 a couple days ago.

[SlientBit]

Hey, v.coinz

I think we have problems again, for sure 

I only mine in P2Pool and no coins have reached my wallet since two days ago, even though they're supposed to.

Here's my allegedly sync'd wallet info:

Hey guys, is the difficulty supposed to be 0.2? I found a block but a few minutes later it disappeared.

Valid blockchain.

Do not use any pool that is not running on valid chain.

ok, try this.

dump it into your virtualcoin folder.

Make sure it is not running.

Now rerun it using "-reindex"


Also, please update your checkpoint.cpp file with following code & also change clientversion.h to 9 1 7
recompile it & then run.

No it's OK. I can connect but it takes a while - and then loses connection every so often. I just think there should be some node servers to make it more stable.

So what's up with the forking? Minep.it sent me ~500 coins and I haven't received anything in my wallet

same problem?? what happened?? i lost more than 5000 coins. wtf

[Iffy]

I pointed my miners at this coin not realizing how little was securing it network wise. I accidentally near 51%'ed it a few days ago and probably caused a fork originating from p2pool. I then cut back and solo mined it for a day or so. Possibly a couple of times my 10Mh/s was 50%ish of the network as others found forks etc, possibly causing more forks.

If so ... sorry about that.

yes, you are right, 51% is what caused forking, all coins including bitcoin has that weakness. We have 2 working pools, but saw once a while most users connecting to 1 pool, causing. Their is no escape that is how decentralize currency works.

OK I've resynced everything. Can you confirm current net hash and block count and difficulty?

The pool had a < little rate already (2Mh/s), I assumed it was ok what with solo miners etc. I have switched to solo only when mining this instead to reduce the chance of causing it again.
