Staking Pool

A staking pool is a service that combines many holders' coins so they can collectively participate in proof-of-stake validation and share the rewards, even if no individual member holds enough to run a validator alone. Proof-of-stake networks often set a minimum stake — Ethereum requires 32 ETH per validator — and demand a machine that stays online around the clock; a pool removes both barriers by aggregating funds and handling operations.

For example, someone holding 0.5 ETH can deposit it with a pool, which batches deposits into full 32-ETH validators run by professional operators. Rewards flow back to participants in proportion to their contribution, minus a pool fee. Liquid staking protocols such as Lido extend the idea by issuing a token (like stETH) representing the pooled stake, which the holder can trade or use elsewhere while rewards accrue. Exchanges offer custodial pooled staking too, and some chains — Cardano, for instance — build stake-pool delegation directly into the protocol, so coins never leave the holder's wallet.

A common misconception is that every staking pool takes custody of your coins; delegation-based and non-custodial designs let you keep your keys, whereas exchange pools genuinely hold your funds — an important distinction when weighing risk. Pool participants still share exposure to slashing penalties if the operator's validators misbehave, and heavy concentration of stake in the largest pools is an ongoing decentralization concern on several networks.
