Crypto Staking: How It Works, What It Pays and What Can Go Wrong
A plain-English guide to proof-of-stake: where staking yield comes from, ETH staking at scale, lock-ups, slashing and taxes.
Where the yield comes from
Proof-of-stake networks pay people to lock coins as collateral and validate transactions honestly. The yield is not interest from a borrower — it comes from protocol issuance plus a share of transaction fees. That distinction matters: staking rewards exist as long as the network exists, but they're paid in the network's own volatile coin, and the rate floats with how many others are staking.
How big staking has become
Staking moved from hobbyist practice to market infrastructure: on Ethereum alone, close to a third of the entire coin supply is now staked, with over a million validators online, and staking has reached mainstream regulated investment products. For institutions hunting yield, a native return on a major digital asset is the draw; for the network, more stake means more economic security.
The four risks people underestimate
First, slashing: validators that misbehave or go offline at the wrong moment lose part of their stake — delegating to a sloppy operator makes their mistakes yours. Second, lock-ups and exit queues: your coins may not be instantly withdrawable, exactly when you most want out. Third, counterparty risk: staking through an exchange adds the exchange's solvency to your risk list. Fourth, the denominator: a 4% yield on an asset that can fall 30% in a quarter is a bonus, not a safety net.
Taxes, briefly
In many countries staking rewards are income at the value when received, and later sales create capital gains on top. Records get messy fast with daily rewards — keep exports from day one. Our staking income and capital gains calculators handle both layers of the arithmetic.
