Title: Is the first Bitcoin network attack just happening? Post by: Raoul Duke on July 16, 2011, 04:00:39 PM Look at this http://blockexplorer.com/
2 last blocks found at the exact same time and now, more than 30min later, no more blocks... WTF?!?! ???

Before someone says it's a block explorer error, well, it isn't. I sent a transaction like 25minutes ago, and still no confirmation, the block number in my client match the one in block explorer.

Everything's fine - there have been incidents of no block being found for over 60 minutes so don't worry and maybe use the time to read up on some statistics (https://secure.wikimedia.org/wikipedia/en/wiki/Poisson_distribution). When no block is found for half a day we should probably start getting suspicious ;) Title: Re: Is the first Bitcoin network attack just happening?

Title: Re: Is the first Bitcoin network attack just happening? Post by: TraderTimm on July 16, 2011, 06:17:29 PM I'd love to see a real-time histogram of the block generation, just so it could allay fears like these. It's just variance, like other posters have said.

Yeah I never really understood why people constantly post stuff like this like what they are posting is never suppose to happen. ::) Title: Re: Is the first Bitcoin network attack just happening?

For the attention. Title: Re: Is the first Bitcoin network attack just happening? Post by: Raoul Duke on July 16, 2011, 07:51:39 PM This is part of a reply from wareen that i got by PM when i had the thread locked.
Gonna post it here for posterity and because it seems you guys will like it At least your thread got me interested to take a look at some block chain statistics - the longest time between two blocks was over 25 hours! That was back in the early months of Bitcoin but nevertheless interesting. Since about January 2010 it was relatively stable with one exception in August 2010 where I think there was some attack due to a bug in the client which had to be fixed manually. The longest interval within the stable period was on May 15th 2011 with 94 minutes! Title: Re: Is the first Bitcoin network attack just happening?
