Very interested to see the code changes - I'm using *nix so need to compile from source Smiley

BTW, overnight CloudCoin went into "locked" mode, just like ORB, only PoS blocks make it into the network now. Mining doesn't work at all.

I believe AndroidTokens (ADT) is also having the same problem.

YES - it is not OrbitCoin exclusive bug. It was inherited from the previous forks.
Just need some rare confluence of conditions for its manifestation.

Bay the way. After of few days of compiling and debugging i finaly patch code and successfully compile/build it under Windows!
My small patch is working - i can mining (PoW) normal now. (I am at 411847 block already - started from current last PoW block 411577 )
But all need to apply this patch or network will be forked. (2 exchanges and block explorer - most important part)

Here is my new (1.2.1) version of OrbitCoin client:
Windows binary: http://yadi.sk/d/8BiaEltqFR844

For those who want to see the all changes in code and try to compile yourself i will try make fork on GitHub (although I have never done that yet, and even there is not registered)

P.S.
To all - do NOT make any transaction now - until it is not clear which of the forks win.

No this changes activates only after 1051200 (1 mil) blocks.

Right, I understand the code now, in the original nSubsidy was shifted zero bits (no change) until after block #1051200. The code rewrite makes it clearer.

But now we at ~410k blocks only. Some bugs it in POS realisation part (Inherited from BitBar/YAcoin or even from NovaCoin or PPCcoin - not sure ORB was forked from, some sight in code point to NovaCoin, but may be fork of the fork of fork...) - sometimes (in some rare situations) POS produce buggy(incorrect) block but it pass check and not rejected/orphaned but included in blockchain.
After this monent all other PoW bloks will be regarded as invalid and rejected - only PoS accepted.

This sounds a little what has happened to CloudCoin (CDC). In that case, PoW blocks are being generated by miners, but the network is reversing most of them within a few minutes. Looks like ORB is not accepting PoW blocks at all though.

For comparison, last 24 hours in the blockchain...

CDC: 1399 PoS blocks, 0 PoW
ORB: 48 PoS blocks, 0 PoW

Both coins broken.

Are a lot of other derived coins with the same bugs going to start failing?  Huh  Lips sealed

P.S.
After many hours I could finally build it under windows. But now it crash just after start...
Will try recompile QT itself + boost from source next time before  compile client. But it so looong and slow...

I think i can temporaly fix network (it is a buggy code, although the original developer thinks that this some kind of attack on network and conspiracy against him  Grin  Grin ).

Would the network stalling be anything to do with the reward change? Won't that affect validating blocks if the network is split between old and new code?

orbitcoin 1.0
Code:
       int64 nSubsidy = 0.25 * COIN;

        if(nHeight < 11)
        {
                nSubsidy = 100000 * COIN;
        }

        nSubsidy >>= (nHeight / 1051200);

orbitcoin 1.2
Code:
       int64 nSubsidy = 0.25 * COIN;

        if(nHeight < 11){nSubsidy = 100000 * COIN;}
        else if (nHeight > 1051200){nSubsidy = 0.25 * COIN;}
        else if (nHeight > 2102400){nSubsidy = 0.125 * COIN;}
        else if (nHeight > 3153600){nSubsidy = 0.0625 * COIN;}
        else if (nHeight > 4204800){nSubsidy = 0.03125 * COIN;}
        else if (nHeight > 5256000){nSubsidy = 0.015625 * COIN;}
        else if (nHeight > 3994560000){nSubsidy = 0 * COIN;}       ********

******** g++ complains "warning: comparison is always false due to limited range of data type" about the last conditional, which I guess means the client will keep generating coins forever. Cheesy


======

This is what debug.log says when my miner submits a found block. I'm not that familiar with the code but I guess it could mean there's an issue with the difficulty calculation. Miner is finding block at supplied difficulty, client rejects PoW as it's the wrong difficulty?

Code:
BitcoinMiner:

No working pools and solomine not work too (at all = 100% rejects). 5th day now
Although transactions are still going through - but only at the rare POS blocks. (if there was no POS generation network would already be dead)

I think i can temporaly fix network (it is a buggy code, although the original developer thinks that this some kind of attack on network and conspiracy against him  Grin  Grin ).
But i even cannot compile it from sourse:
on the official site only binary files.
And source at https://github.com/Orbitcoin/Orbitcoin not compile - lot of random errors (wrong path, wrong includes, wrong functions call from libs etc). Think it is not same version from which it was current binaries for windows created...


I Try
both console deamon and full GUI QT wallet.
MinGW 4.8.1
QT 4.8.5
boost (source of majority of problems at compiling) boost_1_43, boost_1_50 / boost_1_53 / boost_1_55
db-4.8.30.NC
openssl-1.0.1

Re-launching my Orbitcoin pool as per request of acckiller. Lets bring this coin alive again Smiley

http://orb.nordicminers.eu

1% fee, proportional payouts and no delays in payouts. 0% Fee during the holidays. Merry X-mas!
I just jumped in the deep end with 600 kh/s.  I've been a fan of your pools.
Does this pool work?
Code:

Round Shares Submitted shares since last found block (ie. round shares)
Est. Shares 241 (done: 111608.71%)
Pool Valid 268977
Your Valid 3642
Pool Invalid 508
Your Invalid 5

Left it on overnight and still 0 confirmed 0 unconfirmed

orbitcoind grabs a heap of CPU for some reason. A basic RPC call like 'getinfo' can take 10 to 20 seconds to respond.

The server itself is not at 100% load.

No change with the newer 1.2 version. It's still a CPU hog, even when it's synced and there are no blocks to verify for a minute or two. It seems to be stuck in a loop doing SOMETHING. Any ideas?

Three yes post and I release orbis coin, orbitcoin clone minus the premine
No, no, no. Enough?

So you want his coin to thrive
I don't want anything in relation to ORB.
