Epoch glossary entry: Chiliz Chain's fixed time unit of 28,800 blocks (~1 day) on Mainnet, governing validator elections, reward distribution, and unstaking cooldowns.
An epoch is a fixed period of time on a blockchain, measured in blocks rather than hours or minutes.
On Chiliz Chain:
Chiliz Mainnet: 1 epoch = 28,800 blocks, or approximately 1 day.
Spicy Testnet: 1 epoch = 7,200 blocks, or approximately 6 hours.
Block production time can vary slightly, which is why epoch durations are approximate. The block count is the source of truth, not the clock.
Epochs act as the heartbeat of Chiliz Chain's Proof of Staked Authority (PoSA) consensus. Epoch boundaries are when the chain updates its validator-related state, including:
Refreshing the active validator set, taking into account each validator's total staked CHZ.
Distributing staking rewards to validators and their delegators.
If you stake CHZ, epochs determine when you can claim unstaked tokens: after unstaking on Chiliz Mainnet, you must wait for the remainder of the current epoch plus 2 full epochs (roughly 3 days) before claiming.
