## Poisson Block Discovery Model & Variance

Solo mining block discovery follows a memoryless Poisson process where every hash attempt has an identical, independent success probability.

- Formula: `P(X >= 1) = 1 - exp(-t / T)`
- `t` is mining duration in seconds
- `T` is mean time between blocks: `T = (Network Hashrate / Miner Hashrate) * Block Time`

Luck percentile table (reference electricity rate 0.08 USD/kWh):

| Luck Scenario | Percentile | Duration | Power (kWh) | Cost @ 0.08 |
| --- | --- | --- | --- | --- |
| 10% Lucky Hit | 10th | ~1 min | 0.0 | 0.00 USD |
| 50% Median | 50th | 8 min | 0.0 | 0.00 USD |
| 90% Bad Luck | 90th | 28 min | 0.1 | 0.01 USD |
| 95% Extreme Drought | 95th | 36 min | 0.1 | 0.01 USD |
