# Plenum (PLNM)

A KawPoW GPU proof-of-work chain. 240-second blocks, 52 PLNM to the finder, halving every 288,000 blocks, capped at 29,952,000 PLNM. No premine, no presale, no development fee.

> A plenum is the chamber between a fan and the rooms it feeds. The fan pushes one loud, uneven stream; the chamber turns it into the same pressure at every outlet. One algorithm, one reward, the same pressure on every card.

## Parameters

| Parameter | Value |
| --- | --- |
| Algorithm | KawPoW (ProgPoW, Ethash) |
| Block interval | 240 seconds, 360 blocks a day |
| Block reward | 52 PLNM, to the finder |
| Halving | every 288,000 blocks (800 days) |
| Supply cap | 29,952,000 PLNM |
| Epoch length | 7,500 blocks, about 31 days |
| DAG at epoch 0 | about 1.07 GB, about 8 MB growth per epoch |
| P2P / RPC | 19007 / 19008 |
| Address prefix | Z |

The first era pays 360 × 52 = 18,720 PLNM a day, 14,976,000 over 288,000 blocks. Each later era halves, so the series sums to exactly twice the first era.
