Title: Probability graph for next block
Post by: CashBitango on January 18, 2013, 03:44:04 AM
Referring to this thread: https://bitcointalk.org/index.php?topic=135604.0 (https://bitcointalk.org/index.php?topic=135604.0)

It would be cool if someone could put together a graph that shows the following:
The historical probability that a block is found after x amount of time. So for example when it's been 1 hour since last block, this might be a 5% chance event, and it happens on average multiple times per day. A 2 hour delay between blocks is perhaps a 1% chance, and it happens on average once per day. A 3 hour delay is perhaps 0.1%, and happens on average every 10 days etc.

My numbers are from the air, but you can see the picture.

I think it would be cool to have such a graph, and to be able to understand the probabilities we deal with.

I think they have that type of graph on blockchain.info, not sure if it's what you're looking for though

It would have to include the dimensions of current network hash rate and difficulty.  If the dificulty is set as a result of an average hash rate of 28 TH/s and the hash rate drops to an average of 18 TH/s the block is very likely to take longer than expected.  However if the reverse was true, the difficulty was based on 28 TH/s and the hash rate was suddenly 70 TH/s blocks would be solved quicker.
