What Is Crypto Staking and How Are Rewards Calculated?

Staking is what replaced mining on most modern blockchains. Instead of burning electricity to win the right to add a block, validators lock up coins as collateral. Behave honestly and the network pays you; try to cheat and part of your stake is destroyed. Your staking yield is the fee for that service.

Where the yield actually comes from

This matters because it tells you whether a yield is sustainable. Proof-of-stake rewards come from two sources: newly issued coins (inflation) and transaction fees paid by users. A 5% staking yield funded mostly by issuance is not free money — every holder who does not stake is diluted by that same issuance. Yield funded by real transaction fees is genuinely earned.

If an advertised yield is far above the network's own issuance and fee rate, the extra is coming from somewhere else — a token subsidy, a lending desk, or a promise someone may not be able to keep. Find out which.

The four ways to stake

• •Solo staking — you run the validator. Highest reward, full control of your keys, but it needs a big minimum (32 ETH on Ethereum), reliable uptime, and you carry slashing risk yourself.
• •Pooled / delegated staking — you delegate to someone else's validator and share the reward minus a commission (typically 5–15%). No minimum, no hardware.
• •Exchange staking — the simplest option: click a button on Binance, Kraken or Coinbase. You pay a larger cut and, more importantly, the exchange holds your coins.
• •Liquid staking — you deposit and receive a tradeable receipt token (stETH, rETH, jitoSOL). You keep earning while using that token elsewhere in DeFi, at the cost of smart-contract risk and a possible price gap between the receipt and the underlying coin.

Calculating what you earn

The headline number is usually an APR. What you actually receive depends on whether rewards compound, how often you can claim them, and what the validator takes. Net yield ≈ (gross APR × (1 − commission)), then compounded at your claim frequency.

Work an example: 10,000 tokens at 8% gross APR with a 10% validator commission gives 7.2% net. Compounded monthly that is roughly 7.44% effective — about 744 tokens a year rather than 800. Small percentages, but they diverge over multiple years.

The costs nobody advertises

• •Lock-up and unbonding: many chains make you wait days or weeks to withdraw (Cosmos ~21 days, Polkadot ~28). If the price crashes during that window, you watch it happen.
• •Slashing: validator downtime or double-signing can burn a slice of the delegated stake. Rare, but real — spread across validators rather than betting on one.
• •Denomination trap: 12% APY paid in a token that falls 40% is a losing trade. Staking yield is denominated in the coin, not in dollars.
• •Tax: in most jurisdictions staking rewards are income at the moment you receive them, at that day's value — even if you never sold.

Is staking worth it?

If you were going to hold the coin for years anyway, staking it with a reputable validator is close to free yield — you are being paid for something you were already doing. If you are actively trading, the lock-up will cost you far more in missed exits than the yield pays. And if you are staking a coin only because the yield is high, you have bought a token you do not want in exchange for a number that can be changed by governance vote.
