What is staking in crypto, in one sentence? It is locking up tokens on a proof-of-stake blockchain so they can help secure the network and validate transactions, in return for rewards paid in that network’s own tokens. It is not interest paid by a borrower, and it is not a savings account. The rewards come from the network itself, from new token issuance and a share of transaction fees, and they arrive in a volatile asset whose price can fall further than the yield ever pays. Staking can be a modest bonus on crypto you already hold long term, not a reason to buy a coin.
Staking only exists on proof-of-stake networks. Bitcoin cannot be staked, because it runs on proof-of-work, where miners compete with computing power rather than locked tokens. Ethereum, Solana, Cardano and Polkadot are proof-of-stake examples, though each network’s rules differ.
What Is Staking in Crypto, and How Does It Work?
A proof-of-stake network needs a way to decide who gets to add the next block of transactions, without the energy race of mining. Its answer is economic: participants lock up, or stake, tokens as collateral. Validators, the nodes that propose and check blocks, are chosen in part according to their stake. A validator that does its job honestly earns rewards. A validator that misbehaves, for example by signing two conflicting blocks, can have part of its stake destroyed, a penalty called slashing.
For an ordinary holder, the mechanics are simpler than the validator’s job. You commit tokens to the network’s staking process, either directly or through a provider, and rewards accrue over time, usually paid in the same token. The first question is never “what is the yield?” but “who holds my tokens, and when can I get them back?”
Before staking anything, it helps to understand the wallet question underneath it. Our guide on crypto wallets: hot vs cold storage explains where private keys actually live, at the point where custody, rather than yield, is the decision. That post is scheduled for 7 November 2026, so it will be live before this article publishes. Staking through an exchange means the exchange holds the keys, with all the counterparty risk that implies.
Three Ways to Stake: Solo, Delegated and Liquid
Running your own validator is the most direct route and the most demanding. On Ethereum, for example, activating a solo validator requires a substantial deposit, 32 ETH, plus a computer running day and night, kept updated and online. Downtime can mean missed rewards or small penalties, and serious misbehaviour means slashing. Delegating means assigning your stake to an existing validator or pool, which does the technical work and shares the rewards, minus a fee. You keep more simplicity, but you take on validator risk: a poorly run or dishonest validator can earn less, get slashed, or, on some networks, expose delegators to part of the penalty. Choosing a validator is therefore a real decision: look at its track record, fee, share of the network, and slashing history.
Liquid staking is the third route, and the one that needs the most care. A protocol takes your staked tokens and gives you a tradeable token in return, representing your stake plus accruing rewards. You can sell or use that token elsewhere while your original tokens stay staked, which solves the lock-up problem. But it adds a layer: a smart contract that can have bugs, a protocol that can fail, and a liquid token whose market price can drift away from the value of the underlying stake in a panic. The Ethereum Foundation’s own proof-of-stake documentation flags exactly this concentration risk, where a few large liquid staking providers end up controlling much of the stake.
What Staking Rewards Are Really Worth
Realistic staking yields on major networks are usually modest, commonly in the low single digits to the low double digits per year, varying with the network, how much is already staked, and the provider’s fee. Treat any platform advertising a very high fixed return with deep scepticism: sustainable rewards come from the network, not from a company’s promises, and a fixed double-digit promise is a classic hallmark of an unsustainable or fraudulent scheme.
The more important maths is in the token’s price. A 6% annual yield means little if the token falls 40% while it is locked, and you cannot sell to stop the fall. Rewards are paid in the token, so a rising yield in token terms can still be a loss in cash terms. Staking also has a tax angle that beginners often miss: in many jurisdictions, staking rewards are taxed as income when you receive them, even if you never sell. Check the rules where you live before staking, and keep records of every reward.
Staking also interacts with the wider crypto ecosystem in ways worth understanding before committing. Our guide on what DeFi is in crypto explains the decentralised applications many staking products sit inside, at the point where a protocol, rather than a network itself, is holding your tokens. And our comparison of Ethereum vs Bitcoin explains why the two largest networks differ so fundamentally on this question, since only one of them can be staked at all.
The Risks the Adverts Skip
Price risk comes first, because it dwarfs the yield. Your stake and your rewards are both denominated in a volatile token. A fall during a lock-up cannot be traded out of, and a recovery afterwards is not guaranteed. Lock-up and unbonding risk comes second: many networks require tokens to stay locked for a set period, or impose a waiting period after you ask to unstake, during which you still cannot sell. Read the exact unbonding period for your network before staking, not the marketing summary.
Slashing risk is third. It is rare for a reputable validator, but it is real, and on some networks delegators share the penalty. Platform risk is fourth: staking through an exchange or a custodial provider means trusting that provider’s security, solvency and honesty. If it is hacked, freezes withdrawals or fails, your staked tokens may be caught up in the failure. Smart contract risk is fifth, mainly for liquid staking and DeFi staking products: a bug or exploit in the protocol’s code can lose funds even when the underlying network is fine.
A sensible approach follows from those risks. Stake only crypto you already intend to hold for the long term, so a lock-up does not force a decision you would not otherwise make. Prefer arrangements where you keep more control, such as non-custodial delegation over a custodial exchange, where that option exists. Above all, if the yield looks too good to be true, assume the risk is being hidden, not removed.
Frequently Asked Questions
Can I stake Bitcoin?
No. Bitcoin uses proof-of-work, where miners compete with computing power. Staking only exists on proof-of-stake networks such as Ethereum, Solana and Cardano.
Is staking safe?
It is not risk-free. The main risks are price falls, lock-up periods, slashing, platform failure and smart-contract bugs.
How much can I earn from staking?
On major networks, typically low single digits to low double digits per year, varying with the network and provider. Very high fixed advertised yields are a red flag, not a selling point.
Do I pay tax on staking rewards?
In many jurisdictions, rewards are taxed as income when received, even if you do not sell them. Tax rules vary and change, so check the rules where you live and keep records of rewards.
What happens if my validator is slashed?
On some networks, part of the validator’s stake is destroyed, and delegators may share the penalty. Choosing a validator with a good track record matters, and spreading stake across validators reduces the damage from any single failure. Ethereum’s proof-of-stake FAQ explains how proof-of-stake validators are penalised and why stake, rather than energy, is what misbehaving validators stand to lose.
