Questions and answers
What is the fifthening?
A nickname for Ethereum Classic's reward cut: the block reward falls by one fifth (20 %) every 5,000,000 blocks under ECIP-1017, where Bitcoin's falls by half.
What changed at block 25,000,001?
Era 6 began. The block reward went from 2.048 ETC to 1.6384 ETC, and the uncle rewards, which are 1/32 of the block reward, fell with it.
Did anything have to be upgraded?
No. The schedule has been part of the client rules since ECIP-1017 was activated at block 5,000,000, so a reward cut is not a fork and needs no upgrade.
