What is staking?

What does staking actually mean?

A proof-of-stake blockchain needs participants to propose new blocks and vouch for other people's blocks. To make lying costly, it asks them to put up collateral first. Staking is the act of providing that collateral. ethereum.org defines it as depositing ETH to activate a validator, a participant in Ethereum's consensus protocol.

The idea is the mirror image of mining. In proof of work, a miner burns electricity to earn the right to add a block. In proof of stake, a validator risks its own coins: follow the rules and it earns rewards; break them in a provable way and the protocol can destroy part of its deposit. Ethereum has worked this way since The Merge on September 15, 2022.

How does staking work on Ethereum?

A validator is software plus a deposit. Its operator sends 32 ETH to Ethereum's deposit contract and runs the required programs on a computer that stays online. From then on, the protocol gives it duties.

1. Deposit. 32 ETH goes into the deposit contract to activate the validator.

2. Attest. In every epoch (32 slots of 12 seconds), each active validator votes on what it sees as the correct head of the chain.

3. Propose, sometimes. In each slot, one validator is picked at random to propose the block and collect its proposer reward.

4. Get paid or penalized. Rewards accrue for timely duties; missed duties cost small amounts; contradictory signatures can trigger slashing.

5. Withdraw. Since the Shanghai/Capella upgrade on April 12, 2023, standard validators have balances above 32 ETH swept automatically to a withdrawal address, and any validator can exit fully.

ethereum.org says rewards come from proposing blocks, including unburnt transaction fees, and from regularly attesting to the state of the network. Rewards are not a fixed rate set by anyone: they depend on network conditions and on how reliably the validator does its job. You can stake through software you run, or let others do it for you, but running a validator always requires a full node somewhere.

What are the different ways to stake?

ethereum.org groups the options into four families. The real difference is who holds the keys and who runs the machine.

Pools mint a receipt token you can move or use elsewhere; we explain how that works, and its specific risks, in liquid staking explained.

What are the risks of staking?

Staking risks come in two layers: the protocol's own penalties, and the risks of whoever you hand your coins to.

• Penalties and slashing. An offline validator slowly loses ETH. Slashing — for signing two conflicting blocks, for example — destroys part of the stake and forcibly removes the validator.
• Liquidity. Exits and withdrawals take time. Ethereum processes at most 16 withdrawals per block, about 115,200 a day, so a long queue means waiting.
• Price risk. Rewards are paid in the staked asset. If its market price falls, a growing number of coins can still be worth less in dollars. See volatility explained.
• Counterparty risk. With services, pools and exchanges you add smart contract bugs, operator misconduct or insolvency to the list.
• Concentration. ethereum.org warns that large amounts of stake controlled by a few organizations create conditions for censorship and single points of failure.

How do US regulators view staking?

In the United States, the SEC's Division of Corporation Finance published a staff statement on May 29, 2025 about "protocol staking". It covered three set-ups: staking your own coins, letting a third-party operator run the validator while you keep control of the coins, and custodial staking. The staff's view was that these activities, as described, do not involve the offer and sale of securities. The statement does not cover liquid staking or restaking, and it says plainly that it has no legal force and does not change the law; the facts of each arrangement still matter.

A staff view is not a rule, and other countries treat staking differently. Taxes on staking rewards are a separate question; see how crypto is taxed and, for the agencies involved, SEC vs CFTC.

What mistakes do beginners make with staking?

• Treating staking rewards like bank interest. They are protocol payments for work, they vary, and the principal can shrink.
• Comparing advertised rates without checking fees. Services and pools take a cut; an exchange's displayed rate is whatever its terms say. Our APR vs APY entry explains why two quoted numbers may not be comparable.
• Forgetting who holds the keys. With an exchange, you own a claim on the exchange, not a validator.
• Assuming you can exit instantly. Withdrawals and exits queue.
• Ignoring slashing when choosing an operator. If an operator misbehaves, the stake that gets slashed may be yours.
