Questions and answers
How is the hashrate computed?
Nobody can measure it directly. It is estimated as the difficulty of the latest block divided by the average block time over the last 100 blocks. Over a short window the figure moves with luck.
Which algorithm does Ethereum Classic use?
Etchash, a variant of Ethash adopted with the Thanos upgrade (ECIP-1099), which slowed the growth of the DAG so cards with less memory can keep mining.
What does hashrate say about security?
Rewriting recent blocks takes more hashrate than the honest miners have. The higher the network hashrate — and the less of it that can be rented elsewhere — the more that costs. Ethereum Classic was reorganised by attackers in 2019 and 2020, when its hashrate was a small share of what Ethash hardware could deliver.
Does a reward cut lower the hashrate?
A cut lowers miners' income in ETC by 20 % at once. Whether hashrate follows depends on the price and on each miner's costs; the chart here shows what actually happened, not a forecast.
