About ECIP-1017

ECIP-1017 established Ethereum Classic's monetary policy, implementing a disinflationary emission schedule inspired by Bitcoin's halving model.

Era Length:5,000,000 blocks
Reduction Rate:20% per era
Starting Reward:5 ETC (Era 1)
Max Supply:~199-210M ETC

The "Fifthening" (20% reduction, or keeping 4/5ths) occurs approximately every 2.5 years, gradually reducing new supply entering circulation.

ETC's more gradual reduction (20% vs 50%) provides smoother transitions for miners while still achieving disinflationary monetary policy.
