module_inflation

x/inflation is a new module introduced in the v7 upgrade. It wraps x/mint and takes over the calculation of the effective inflation rate.

Introduction

v7 introduces x/inflation, which controls the total supply cap and gradually reduces the inflation rate over time.

How inflation decay works

The inflation rate decreases each month by a fixed percentage (compound decay), so early stakers benefit from higher inflation before it tapers off.

inflation_rate = base_rate × (1 − decay_rate) ^ months_elapsed

Where:
  base_rate      = 1% (fixed; InflationMin = InflationMax = 0.01)
  decay_rate     = 6.8% per month
  months_elapsed = blocks since upgrade height ÷ blocks per month

Inflation is always ≥ 0 and never goes negative.

Mainnet parameters

Parameter	Value
Max supply	100 billion CRO (10^19 basecro)
Decay rate	6.8% per month
Decay start	v7 upgrade block height
Base rate	1% (fixed min/max)

The chain halts if circulating supply exceeds the max supply cap. Balances held at designated burn addresses are excluded from the circulating supply calculation.
