Staking Glossary: 20 Terms Every Staker Should Know

Core network terms

Validator — a participant that locks a deposit and takes part in proposing and attesting to blocks. Attestation — a validator's signed vote that a particular block is the correct head of the chain; correct, timely attestations are the bulk of a validator's earnings. Epoch — a fixed batch of slots after which the network tallies votes and updates balances. Finality — the point after which reversing a block would require destroying an enormous amount of staked value.

Churn limit — the cap on how many validators may join or leave per epoch, which is what creates entry and exit queues. Withdrawal credentials — the address that ultimately receives a validator's balance; separating these from signing keys is a core safety practice.

Reward and penalty terms

Issuance — newly created currency paid by the protocol to validators. Priority fee — a tip attached to a transaction to encourage faster inclusion. MEV — value extractable from choosing the order of transactions within a block. Commission — the share of rewards taken by an operator or protocol.

Inactivity penalty — a small deduction for missing attestations, recoverable by coming back online. Slashing — a severe penalty plus forced exit for provably harmful actions such as signing two conflicting blocks. Effective balance — the rounded balance the protocol uses when calculating a validator's rewards and duties.

Liquid staking terms

Liquid staking token (LST) — a transferable token representing a share of a staked pool. Rebase — a protocol-wide balance update that credits rewards without a transfer. Wrapped token — a fixed-balance version of a rebasing token whose redemption rate rises instead. Redemption rate — how much of the underlying asset one receipt token is worth when redeemed through the protocol.

Depeg — a market price that has drifted away from the redemption rate. Buffer — undeployed deposits a protocol keeps on hand to serve withdrawals instantly. Restaking — reusing staked capital to secure additional services, which layers extra slashing conditions on top of the base stake.

Where to go next

With this vocabulary in place, the rest of the material on this site reads much faster. Start with the fundamentals of receipt tokens, then move to how rewards are actually computed, and finish with the risk breakdown before committing capital anywhere.

Lido Finance terms you will meet

A few names recur constantly: Lido Finance, the largest liquid staking protocol on Ethereum; stETH, its rebasing receipt token; wstETH, the wrapped fixed-balance version; and the withdrawal queue, the mechanism that converts either back into ETH. Knowing these four makes most liquid staking documentation readable.
