Staking explained: how it works and what it really pays

Staking is presented to beginners as “earning interest on your crypto”. That framing is misleading enough to cause real losses, so it is worth being precise about what is actually happening.

What staking actually is

On a proof-of-stake network, security comes from participants committing capital rather than burning electricity. When you stake, you lock coins as collateral. The protocol uses that stake to weight your role in proposing and attesting to blocks, and pays you newly issued coins for participating honestly.

So you are not lending to anyone and there is no borrower paying you interest. You are being paid to perform a job for the network, and the payment is inflation — new supply issued to you and diluting everyone who is not staking.

Where the yield genuinely comes from

Three sources, and it matters which one you are looking at:

• Protocol issuance. New coins created by the network. Real, sustainable, and typically modest — low single digits on major chains.
• Transaction fees. A share of fees paid by users. Real, and varies with network activity.
• Token emissions from a platform. A service paying you in its own token to attract deposits. This is not income; it is dilution of that token, and the rate usually collapses once emissions slow or everyone sells.

If an advertised yield substantially exceeds what the underlying protocol pays, the difference is coming from the third category, from lending your assets out, or from someone else’s deposits. Ask which, and treat a vague answer as an answer.

The four risks behind the percentage

1. Price risk — usually the dominant one

Rewards are paid in the coin you staked. A 5% annual yield on an asset that falls 40% is a 37% loss. The percentage is denominated in the thing whose price is the actual variable, which is why comparing it to a savings account is category error.

2. Lock-up and exit queues

Many arrangements prevent withdrawal for a fixed period, and some networks have an exit queue that lengthens when many validators leave at once — precisely during a market panic. You can be unable to sell during exactly the fall you would most want to exit.

3. Slashing

Validators that misbehave or go offline can have part of their stake destroyed. If you delegate to someone else’s validator, their failure can cost you. Check the operator’s track record and whether they offer any slashing cover.

4. Counterparty risk

Staking through an exchange or a liquid-staking service means trusting that platform in addition to the protocol. That is a different and additional risk from staking directly, and platform failure has cost stakers their entire position more than once.

The ways to stake

• Solo staking — run your own validator. Maximum control and no counterparty, but high capital requirement and real operational responsibility.
• Delegating — assign your stake to a validator operator. Simple; you take on their performance risk.
• Exchange staking — easiest, worst on counterparty risk, and the platform typically keeps a large share of the reward.
• Liquid staking — receive a token representing your staked position, which stays tradeable. Convenient, adds smart contract risk, and the token can trade below the value of the underlying.

Questions to ask before staking anything

• What is the protocol’s own issuance rate, and how does the advertised figure compare?
• Can I withdraw, and how long does it actually take?
• Who holds the keys while it is staked?
• What happens if the validator misbehaves?
• Am I comfortable holding this asset for the whole lock-up regardless of price?

If the last answer is no, the yield is irrelevant.
