Cardano is a Proof of Stake (PoS) blockchain. This means that even if you do not have the time or resources to run a stake pool, you can still delegate your ADA to another pool operator (like plebpool) and have it staked on your behalf. IMPORTANT: when you stake you aren’t sending your ADA to the pool but are delegating it, so this means ADA never leaves your wallet. Read below for epochs and payouts for staking rewards!

Epochs and payouts
An Epoch is a period in which new blocks are created through slots. Slots occur every 20 seconds within an epoch, and each epoch lasts exactly five days.
Epoch 1: The epoch in which you delegate your stake will be ‘epoch one’ for rewards purposes,
Epoch 2: Your delegation becomes active and your delegation preferences are updated on the blockchain. During this epoch, your chosen stake pool should produce a block,
Epoch 3: During this epoch, your rewards are calculated,
Epoch 4: Your delegation rewards are distributed.
