 at least you kept your humor. LoL. I was considering that but before I knew it I was at the back of the queue for "losing my humour" so decided to laugh instead  |

Even in the event that an attacker gains more than 50% of the network's
computational power, only transactions sent by the attacker could be
reversed or double-spent. The network would not be destroyed.

Change log for this version? I can't seem to find any info over at darkcointalk. Am I the only one who gets nervous when a download link is only provided on BCT? I always feel better when I see the update info on both BCT and DCT so that I know ED's BCT account wasn't hacked and linking to a virus. Anyways the link points to the right repository so I updated my MN's to .24. OK enough acronyms for now. |

Is there any reward for discovering bugs and vulnerabilities? I have found several other bugs.
Glade to see there is some code review from outside and FOUND (some) bug(s). It makes the Darkcoin project more healthy and strong. Many thanks to Mr. Spread if you could share your discovering~  EDIT: I'm pretty sure you could get some reward if you post the bugs on Darkcointalk or here . This is one of the greatest community in Crypto world~ Maybe the BEST~ As usual, the quick response and action. Great job, Evan and the Dev-team. Looking forward to crash other bug(s) before we start the InstantX testing. And finally, we get some volatility~ |

Anyone knows why average spacing between DarkCoin blocks is approximately 157 seconds instead of 150 seconds? I remember that when creating SpreadCoin several months ago I noted that there is a small bug in DarkCoin difficulty retarget which causes block generation to be a bit slower than it should be. But it seems that I lost this knowledge. When I'm now looking at difficulty retarget it looks correct to me, although a bit obfuscated.

This has been known for some time and isn't worth fixing. I'll explain why: https://github.com/darkcoin/darkcoin/blob/master/src/main.cpp#L1607https://github.com/darkcoin/darkcoin/blob/master/src/main.cpp#L1453One of them is computing 24 blocks and one is computing 23. So: 1/24.0 == 0.0416 2.5*1.0416 == 2.604 (minutes) Statistically it's doing exactly what it should! |

So: 1/24.0 == 0.0416 2.5*1.0416 == 2.604 (minutes) Statistically it's doing exactly what it should! Here is the DarkCoin retarget formula freed from any obfuscation and without clamping:  where T i is the target of i-th block and t i is the timestamp of i-th block. Initially I thought that this is because previous block is counted twice but it is divided by 25, not 24, so it's ok. But look at actual timespan computation: t i-1 - t i-24 but 24 - 1 = 23, so it is actually timespan of 23 blocks. 23 blocks per hour instead of 24. This is 156.522 seconds or 2.6087 minutes of spacing between blocks. By the way, I don't see here any "multiple exponential moving averages" as white paper states, where are they? |

What's with all these "Spread" accounts now? Even Mr. Spread sounds belligerent. Not a good way to make a first impression gentlemen. |

Tens of bugs and vulnerabilities have been found in prior reviews. It will take some more time (and more eyes) to make it bulletproof. Personally I think the whole Masternode payment system should be replaced by another cleaner system that works at the protocol level. No enforcement or centralization would be necessary, while eliminating forking risk. Perhaps the spreadcoin dev might want to have a go at such a system. |

What centralisation? Whats clean about thousands of clients going on and off every second while trying to maintain rounds of anonymity? That would juts cause mayhem. What is unclean about blind nodes with 100% uptime? And what about PoService? I dont get it. |

I don't remember when you got on board, but prior to the semi-voluntary scheme of payments with enforcement threat, there was a direction of mandatory payments (100%) with no enforcement needed whatsoever. Unfortunately it caused forks in the production environment so then we got to a situation where some people were calling for no hard forks, others were in favor to get the job done - even if it includes a few more problematic forks as a byproduct etc etc. Then we got the spork and the rest is history. |
