## 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`
