Title: [SCRYPT] Probability of not solo mining a block in a period of x time? Post by: 01BTC10 on February 09, 2014, 07:27:21 PM I'm actually solo mining Dogecoin with my own private MPOS pool. The CoinWarz calculator tells me that I should mine one block per 0.65days however I've been mining for 2 days without solving any block.
How could I estimate the probability of not finding a block for a period of x days ? I'm wondering if I screwed something in my pool setup.

Post by: Test User on February 09, 2014, 07:31:18 PM This is a simple application of the Poisson distribution.
Lambda = Expected number of blocks per day Prob (No blocks) = e ^ -Lambda In your case, 1 block per 0.65 days = 1.54 blocks per day. P(No blocks) = e^ -1.54 = 21% Title: Re: [SCRYPT] Probability of not solo mining a block in a period of x time? Post by: 01BTC10 on February 09, 2014, 07:37:21 PM Thank you sir.

Lambda = expected number of blocks in the period So, for 2 days, lambda = 3.08 P(No block) = e ^ -3.08 = 4.5% Title: Re: [SCRYPT] Probability of not solo mining a block in a period of x time?
