What Is Crypto Staking and How Does It Work?

Staking is a process where you commit your cryptocurrency tokens to support the operation and security of a blockchain network. In return, you may receive additional tokens as rewards.

People often compare staking to earning interest on money in a savings account. That can be a useful starting point, but the comparison is limited. Unlike money in a UK bank account, staked crypto is not protected by the Financial Services Compensation Scheme (FSCS). Rewards are not guaranteed, prices can move sharply, and you can lose all of your capital.

When you stake your cryptocurrency, the network uses your assets as part of its transaction validation process. If everything works as intended, you receive rewards in the same cryptocurrency. If things go wrong, you bear the risk.

Staking is not currently a regulated activity in the UK, but that is changing. From October 2027, any firm offering staking services to UK customers will need permission from the Financial Conduct Authority (FCA). Firms can start applying for this permission in September 2026. If you are using a staking service today, it is worth checking whether the provider plans to seek FCA authorisation under the new rules.

The mechanics behind staking

Staking exists on blockchains that use a consensus mechanism called Proof of Stake.

A blockchain is a shared digital record of transactions. It needs a way for participants to agree on which transactions are valid, without a central authority like a bank. Different blockchains use different systems to reach this agreement.

In Proof of Stake systems, the network selects participants to help validate transactions based on the amount of cryptocurrency they have committed, or "staked". Instead of using large amounts of computing power, the system relies on people locking up their tokens.

Because participants have their own assets at risk, they are encouraged to follow the rules of the network. In some networks, if a participant behaves dishonestly or fails to meet technical requirements, a portion of their staked tokens can be taken away. This is often called "slashing".

Not every cryptocurrency can be staked. Staking is only possible for assets that are native to Proof of Stake or similar networks. Well-known examples that support staking include Ethereum (ETH), Cardano (ADA), Solana (SOL) and Polkadot (DOT). Each one has its own rules, reward structure and risks.

How staking works in practice

If you decide to explore staking, you will usually follow a series of steps. Each step involves choices and risks, and the process can be technically complex for beginners.

• Acquire a supported cryptocurrency that runs on a Proof of Stake (or similar) network. You should understand how the asset works, why you hold it, and be prepared for high volatility in its value.

• Transfer your tokens to a compatible digital wallet or a platform that offers staking. Software wallets can be used from a phone or browser. Hardware wallets, such as Ledger devices, allow you to manage staking while keeping your private keys offline. Some specialised staking services let you stake through a pooled service. These options each carry different security, smart contract and counterparty risks.

• Start the staking process and agree to any lock-up or notice period. Depending on the network and platform, your tokens may be locked for a set time, or you might face a delay of several days or longer when you request to unstake. Some services offer more flexible options, but these often come with different fees, lower rewards or additional risks.

• Once staked, your tokens help the network validate and record transactions. If the process works as expected, the blockchain or staking service credits rewards to your account over time. The size and frequency of rewards typically depend on the amount staked, network conditions, protocol rules and any fees charged by validators or platforms. Rewards can change and are not guaranteed.

At every stage there is a risk of loss. Technical errors, hacking, changes to protocol rules or failures at a third-party service can all affect your staked assets and any rewards you might expect.

Risks and how to stay safer

Staking is often marketed as a way to "earn yield" on crypto holdings. It is important to look past the marketing and understand the key risks involved.

• Market risk and price volatility. Crypto markets are highly volatile and can move quickly. For example, if you stake £1,000 of tokens and earn 5% over a year, but the token price halves in that period, your holdings would be worth around £525, not £1,050. In many cases, rewards will not offset a major price drop.

• Lock-up periods and liquidity risk. Many staking options restrict how quickly you can access your funds. If your tokens are locked and the market rises or falls sharply, you may not be able to sell at the price you want. Even where "flexible" staking is offered, there can be delays, withdrawal limits or penalties.

• Slashing and protocol risk. On some networks, if the validator you use behaves incorrectly or fails to meet technical standards, part of your staked tokens can be taken away. Even if you are using a service provider, you still bear this risk.

• Platform and counterparty risk. If you use an exchange, staking pool or DeFi protocol, you are exposed to the risk that the platform is hacked, mismanages funds or becomes insolvent. In such cases, you may lose some or all of your staked assets. There is typically no FSCS protection if this happens.

• Fraud and scams. Fraudulent projects often advertise extremely high or "guaranteed" staking returns to attract deposits, then shut down or disappear with customer funds. Once the money has gone, it is often very difficult or impossible to recover.

To reduce, but not remove, some of these risks:

• Research the cryptocurrency, network and staking method carefully.
• Use well-known platforms with a track record, and check whether they are registered or regulated for any services in your jurisdiction.
• Treat any offer of very high, fixed or "risk-free" returns with extreme scepticism.
• Only stake funds you can afford to lose, and consider diversifying rather than putting everything into one token or platform.

Even if you follow these steps, you can still lose money.

Summary

Staking lets crypto holders help secure and operate certain blockchain networks by committing their tokens to the protocol. In return, they may receive rewards, usually paid in the same cryptocurrency.

This can be attractive to people who already hold crypto and are comfortable with long-term exposure to a particular asset. However, it is not similar to earning interest in a bank account. Crypto values are highly volatile, rewards can change or stop, lock-up rules can prevent you from exiting when you want, and you may lose all of your capital.

In the UK, HMRC generally treats staking rewards as taxable income when received, with capital gains rules applying when you later dispose of the tokens. Speak to a tax professional if unsure. CoinJar does not offer staking.

Before staking, make sure you fully understand how the specific token, network and platform work, the risks involved, and how you would cope financially if the value of your investment fell to zero.
