Staking Pool

Most Proof of Stake networks set a minimum amount of crypto a participant must lock up to run their own validator node, and that bar can be steep: Ethereum requires 32 ETH, worth well into six figures at most points in its history. A staking pool removes that barrier by letting a group of holders contribute smaller amounts each, which a pool operator then combines and stakes on their behalf through one or more validator nodes.

Operationally, participants deposit tokens into the pool's smart contract or platform, and the operator handles node uptime, software updates, and key management, tasks that would otherwise require dedicated hardware and technical know-how. When the pool's validators earn block rewards, the operator deducts a service fee, typically a few percent, then distributes the remainder proportionally to each contributor's share, similar to how a delegator earns a cut of a validator's output on delegated networks.

Two broad models dominate: custodial pools run by centralized exchanges, and non-custodial protocols where users keep control of their funds via smart contracts. Many of the latter fall under liquid staking, issuing a tradable receipt token, such as stETH or rETH, that represents the staked position and can be used elsewhere in DeFi while the underlying assets remain locked.

Risks include operator fees eating into yield, smart contract exploits, and slashing penalties passed on to pool members if a validator misbehaves. Concentration is also a concern: a handful of large pools have at times controlled a large share of a network's total staked supply, raising questions about censorship resistance.
