What is staking, actually?

Staking is how proof-of-stake blockchains secure themselves and validate transactions — locking up crypto as a kind of collateral in exchange for a role in running the network.

What "locking up" actually means

Staked coins are committed to help validate new blocks. In return for this participation, and for putting value at risk that can be penalized for bad behavior, stakers earn rewards — new coins issued by the protocol, transaction fees, or both, depending on the network.

Where the rewards actually come from

Unlike a savings account's interest, which comes from a bank lending out deposits, staking rewards typically come from the protocol's own issuance schedule (new coins created according to the network's rules) plus a share of transaction fees — not from a company generating profit and sharing it with you.

The main risks involved

"Slashing" penalties can reduce your staked amount if the validator you're staked with misbehaves or goes offline — a real risk when choosing which validator to delegate to. Many networks also impose a lock-up or "unbonding" period before staked coins can be withdrawn, meaning your funds aren't always immediately liquid.

Staking directly vs. through an exchange

Running your own validator node requires technical setup and a minimum stake that's often out of reach for individual holders. Staking through an exchange or a staking pool lowers that barrier, but adds back some custodial risk — you're trusting that platform with your coins, the same tradeoff discussed in custodial vs. non-custodial wallets.
