I don't really get the purpose of this thread. You know such things happen. Sometimes there are 12 blocks in a hour, and sometimes not a single one.

I've never seen anything close to an hour for a block so this seems ridiculous to me, especially for a tech with the promise of fast transaction times. I was hoping to start a discussion on the topic (this is bitcoin talk after all) ![Grin](https://bitcointalk.org/Smileys/default/grin.gif)

It seems weird to me too. Can I now assume that the next difficulty increase will slow down now?

When this happens it can mean only one thing! Miners are on break(actually they are watching porn) and all the mining gears stopped mining! It's very probable someone with a very high % of THS just stopped their gear for some maintenance! Everything will return back to normal soon ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

75 min pauses happens quite frequently. Now a 8 hours pause, that would be interesting ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif)

It could very well be a result of SELFISH MINING as Ghash has found back to back blocks and has around 50% of the network hashing power just about and maybe even greater?The possibility is very Real! http://bitcoinmagazine.com/7953/selfish-mining-a-25-attack-against-the-bitcoin-network/ I'm part of the minority But the majority of people won't acknowledge the threat or just put there head in the sand and pretend the threat doesn't exist? and will always give them the benefit of the doubt?There's been plenty of spans of them finding 6 blocks in a row continuously which shows of this strong possibility ![Shocked](https://bitcointalk.org/Smileys/default/shocked.gif) The threat is very real and the problem just keeps getting worse but majority doesn't want to do anything or even fathom the possibility they will say it's anything But ? Do some research and You can decide for yourself and don't listen to what people say?Do some googling Ghash has already has a history of double spending so it's not far out of the realm of possibility especially with 50% hashing power of network...... But we also have plenty of Selfish miners that will stick with them and they don't care about it as long as they are getting paid which is just another part of the problem in itself......... Maybe I'm wrong ?but then again maybe I'm Right? The theory is as good and valid as anything else anyone has to say because nobody can prove that they are or they aren't?

And the one before that was only 4 minutes apart... ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) The difficulty of the network is set so that, on average one block will be mined every 10 minutes. This is an average and like all averages, each data point will be different. If the hashrate of the network decreases after the difficulty changes then it will take longer then 10 minutes per block (on average). The opposite is true as well.

Assuming that the difficulty is set 10% lower than the actual hash rate (it's probably nearer 7% now) then we'll see no blocks found in an hour about once every month. If the difficulty exactly matched the hash rate then this would happen about once every 17 days. It's not a bug, it's not anyone doing anything malicious, it's just the way that mining is set up to work: http://hashingit.com/analysis/27-hash-rate-headaches

It seems weird to me too. Can I now assume that the next difficulty increase will slow down now?
Doubt that will happen, its all about luck and diff here. its possible to have blocks minutes apart, as it is having them hours apart, but unlikely. As far as diff is concerned, it will go straight up, no doubt about that, and that is becose more and more miners are joining and expanding.

As far as diff is concerned, it will go straight up, no doubt about that, and that is becose more and more miners are joining and expanding. I think the evidence is that it's already slowed down dramatically (although it's still going up at a very high rate). Certainly there's still a lot of scope for it to increase 10x more than it is right now. The BTC price strongly influences this as it increases the total available mining reward but ASICs are close to hitting a technology brick wall. That will mean the only way to get more hashing capacity for the same money is for hardware to be heavily discounted and eventually the hardware suppliers will hit margins that they can't go below. Similarly as we hit limits on the power consumption per unit amount of hashing we'll see energy costs taking a larger fraction too. Once the expansion rate gets down to 5% (that could be this year or could be next) then statistical noise will mean we'll even see occasional difficulty reductions.

For the sake of argument best asic = .4 watts for 1 gh at the wall plug . The sp30 is close to that. At 650 usd a coin and .4 watts the sp30 stops paying for power at about a diff of 125 to 250 current diff is 11.7 Most 1th 1000 watts machine can't pay for power at 60 to 125 . so come winter diff could drop or maybe just maybe coins go from 650 usd to 3000 usd. time will tell

Would be good to see something different happen ? Someone correct me but if there is no blocks for 75 minutes doesn't this mean nobody in the world can securely move their BTC from one wallet to the next. Surely Im misunderstanding because that's really naff hopefully Im totally wrong ![Shocked](https://bitcointalk.org/Smileys/default/shocked.gif)

I was hoping to start a discussion on the topic (this is bitcoin talk after all) ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Not that ridiculous, it's bound to happen. A Bitcoin block can be found at any moment, the difficulty is just chosen so that it will take on average 10 minutes. But mining is just like lottery, if another block is found 5 seconds after the first one, OK, it happens. If you throw a coin, 50 % of the time it will be heads. But if you throw it 10000 times, there will be long streaks of either. Bitcoin mining is not the same but 8 times the usual block time is not that unusual. A poisson process is a good model for how the blocks are found. You can work the probabilities out with basic high school math, it's not as simple as some discete probability problems such as coin flipping but a very simple model anyway.
