ECIP-1017Eras and block rewards
5,000,000 blocks per era; on entering a new era the reward falls by 20 %. The table follows from the rule; start dates of past eras are read from the chain.

The rule
- Era length
- 5,000,000 blocks
- Era 1 reward
- 5 ETC
- Each new era
- previous reward × 0.8
- Reward of era n
- 5 × 0.8^(n−1) ETC
- First block of era n
- (n−1) × 5,000,000 + 1
- Uncle rewards, era 2 on
- 1/32 of the block reward, to the includer and to the uncle's miner
Reading the table
“ETC per day” is the era's reward times the number of blocks in a day at the block time measured now; it is left out when no block time is known.
“Issued in era” is 5,000,000 blocks times the reward. Uncle rewards come on top and depend on how many uncles are included, so they are not part of this column.
Questions and answers
What is an era?
ECIP-1017 calls each run of 5,000,000 blocks with one reward level an era. Era 1 is blocks 1 to 5,000,000 with 5 ETC per block; each later era pays 20 % less than the one before.
Why 20 % and not a halving?
ECIP-1017 chose smaller, more frequent steps than Bitcoin: 20 % every 5,000,000 blocks, which is a little over two years at Ethereum Classic's block time. Over about two eras the reduction is comparable to one Bitcoin halving every four years.
Does the schedule ever end?
No era is the last one in the rule. The reward keeps shrinking by 20 % and eventually rounds down to nothing in the smallest unit; long before that it is a tiny fraction of an ETC.
Where do the start dates come from?
Start dates of past eras are the timestamps of their first blocks, read from the chain. Start dates of future eras are estimates from the current height and the measured block time.
