Epoch

wikipedia:Epoch (computing)

In Ethereum 2.0 progress on the network is recorded in epochs, for Bitcoin and the Ethereum Mainnet, progress on the network is recorded in blocks. Ethereum epoch is the unit of time — and time in ETH 2.0 is divided into slots.

• Cardano epoch change every 5 days: https://cexplorer.io/epoch

• Ethereum validator: ETH1_VOTING_PERIOD is defined as 32 epochs (~3.4 hours)
