What is staking?

The short answer

Staking is the act of locking up a blockchain's native coins to help run and secure a proof of stake network, in exchange for rewards. On networks like Ethereum, Solana, and Cardano, the participants who propose and confirm new blocks are called validators, and they must put up coins as collateral. If they do their job honestly, they earn newly issued coins and fees. If they misbehave, they can lose part of their stake.

For most people, staking means delegating coins to a validator or depositing them with a service rather than running a validator themselves. The coins remain yours, but they are committed to the network for a period and cannot be sold instantly. In return you receive a share of the rewards, often expressed as an annual percentage yield.

Staking is frequently compared to earning interest, but the comparison is loose. The reward is not paid by a borrower. It comes from the network's issuance schedule and transaction fees, and it is compensation for helping secure the chain and for accepting certain risks. Thinking of it as payment for a service, rather than interest, keeps the risks in view.

How staking secures a network

In proof of stake, the right to produce blocks is tied to how much a participant has at stake. Validators are chosen, often randomly weighted by stake, to propose a block, and other validators attest that it is valid. A block becomes final when enough stake has signed off on it. Because validators have coins locked up, they have a financial reason to follow the rules.

If a validator signs two conflicting blocks or goes offline for long periods, the protocol can penalize them. Serious violations trigger slashing, where part of the stake is destroyed and the validator is removed. Attacking the network would require controlling a large fraction of all staked coins and then losing most of them when the attack is detected.

This design replaces the electricity and hardware spent in proof of work mining with locked capital. It is the reason Ethereum's energy use fell by roughly 99.9 percent when it switched to proof of stake in September 2022, and it is why staking rewards exist: they pay validators for providing the collateral that keeps the network honest.

Ways to stake

Solo staking means running your own validator. On Ethereum this requires 32 ETH, a dedicated computer that stays online continuously, and the technical skill to maintain it. It gives you full control and the full reward, with no middleman, but it is the most demanding option. Solo stakers also bear all of the penalties if their node misbehaves or goes offline.

Delegation is available on networks like Solana, Cardano, Cosmos, and Polkadot. You keep the coins in your own wallet and assign their voting weight to a validator you choose, who takes a commission from the rewards. You do not hand over custody, and you can usually switch validators after an unbonding period.

Liquid staking protocols such as Lido and Rocket Pool pool deposits from many users, run validators on their behalf, and issue a token representing the staked position, for example stETH. That token can be traded or used in DeFi while the underlying coins keep earning. Exchanges also offer staking, where the exchange holds your coins and passes on rewards minus a fee.

• Solo staking: run your own validator, full control, highest effort
• Delegation: assign stake to a validator while keeping custody
• Liquid staking: receive a tradeable token representing your stake
• Exchange staking: simplest, but the exchange holds your coins

Rewards and what affects them

Staking yields vary by network and over time. They depend on the chain's issuance rate, the share of total supply that is staked, transaction fee volume, and any commission charged by the validator or service. When more coins are staked, each one earns less, because the fixed pool of rewards is split among more participants.

On Ethereum, solo staking yields have generally been in the low single digits annually, while networks with higher issuance such as Solana or Cosmos have offered more. A higher percentage is not automatically better. If a network issues many new coins to pay stakers, that issuance dilutes everyone, including stakers, and the nominal yield partly offsets inflation rather than adding real value.

Rewards are typically paid in the staked coin, so the dollar value of what you earn rises and falls with the coin's price. A 5 percent yield on a coin that drops 40 percent is still a loss in dollar terms. Staking is best thought of as a way to grow a holding you already intend to keep, not as a substitute for considering whether to hold the coin at all.

Risks and tradeoffs

The first risk is lockup. Many networks impose an unbonding period of days or weeks before staked coins can be withdrawn, and some enforce a waiting queue. If the price falls sharply during that window, you cannot sell. Liquid staking tokens address this, but they can trade below the value of the underlying coins when the market is stressed.

The second risk is the validator or service. A validator that goes offline earns less, and one that is slashed loses part of its stake, including your delegated share. An exchange or protocol that holds your coins can be hacked or become insolvent. Choosing reputable, well established operators and diversifying across them reduces but does not remove this risk.

Smart contract risk applies to liquid staking protocols, which are code that can have bugs. Tax treatment of staking rewards varies by country and can be complex. And a concentration risk exists at the network level: if one liquid staking provider controls a very large share of all stake, it gains outsized influence over the chain, which many in the community see as a problem.

How to get started

First decide whether you want to hold the coin regardless of staking. Then pick a method that matches your technical comfort and the amount involved. For most beginners, delegating from a self custody wallet on a network that supports it, or using a large liquid staking protocol, offers a reasonable balance of simplicity and control.

When choosing a validator, look at its commission, uptime history, total stake, and whether it is run by an identifiable operator. Spreading stake across smaller validators supports decentralization and limits the damage if one fails. Check the unbonding period before committing so you are not surprised when you want to exit.

Keep records of rewards for tax purposes, and revisit your choice periodically. Validators change their commissions, protocols get upgraded, and the balance between yield and risk shifts over time. Checking in every few months to confirm your validator is still performing well, that rewards are arriving as expected, and that your chosen method still suits your needs takes little effort and prevents unpleasant surprises.
