Mr.spread,what's status of masternode and darksend developmnet?

It is far from ready yet but I think I found a potential vulnerability in DarkCoin which allows miners (actually pools) to not pay part of the block reward to masternodes.
DarkCoin wallet checks the following things for each new block:  
1) There is a payment to master node.
2) There is a payment with the same amount as a payment to master node should be (30%).
But there is no check that this is the same payment. This means that if you generate a block you can pay 0.0000001 DRK to masternode and pay 30% and (70% - 0.0000001 DRK) to yourself as separate coinbase outputs. Such blocks should be accepted by DarkCoin network but I haven't tested it on testnet so I can't be 100% sure.

I don't want any vulnerabilities out the wild so thought I'd check here.  This is what happens when "Enforcement" is off, right?  Or is this a separate issue and potential vulnerability?

Excellent work once again, Mr. Duffield, bug spotted, bug squashed in short order...

Don't forget to thank Mr. Spread for discovering the bug!

Thank you Mr. Spread for discovering the bug! Fixed.

Maybe he tries to hold the price on these levels   .

The latest shift for the Darkcoin multipool paid out over 92DRK.

Still need more hash for Sha256, Scrypt & X11 algo. If you got some, bring it over!

Cheers!

Lets keep this thread on track with Darkcoin. Bugs and fixes, fine, everything else, keep in respective threads. Too many times people use this thread to gain exposure to other coins since it is one (if not the longest) of the most active altcoin thread on BCT.
