Staking and validators: how proof-of-stake networks pay for security

Staking is how a proof-of-stake blockchain pays for its own security. Instead of miners burning electricity to prove they've done costly work (proof-of-work, the Bitcoin model), validators lock up the network's native token as collateral and earn rewards for confirming transactions honestly. Lock up the wrong way, get slashed. Lock up honestly, earn yield.

How it works

A validator runs software that proposes and confirms new blocks. To participate, it locks (stakes) a minimum amount of the network's token, 32 ETH on Ethereum, as a bond. The network selects validators to propose and attest to blocks in rough proportion to how much they've staked. Confirm blocks correctly and in sync with the rest of the network, and the protocol pays a reward, typically a mix of new token issuance and transaction fees.

Get it wrong and the penalties bite. Going offline costs a small, gradual penalty. Equivocating, signing two conflicting versions of the same block, or otherwise acting maliciously triggers slashing: an automatic, often severe cut to the staked amount, sometimes the validator's entire bond. The economic logic is direct. Honest validation is the only strategy that reliably pays, because dishonesty is priced to cost more than it could ever earn.

Running a validator directly requires the minimum stake, dedicated hardware, and constant uptime, which is out of reach for most holders. Staking pools and liquid staking protocols solve that by pooling smaller deposits into professionally run validators and distributing the rewards pro rata, without each depositor needing to run their own node.

Why it matters

Staking is what makes a proof-of-stake network expensive to attack. To rewrite history or censor transactions, an attacker needs to control a supermajority of the staked capital, and doing that means buying and locking up a sum of the native token large enough to move its own market price against the buyer. The security budget of the network is, literally, the dollar value of everything staked.

For anyone earning yield in crypto, staking is also the base case against which every other yield source gets measured. Staking rewards come from the protocol's own issuance and fee revenue: a claim on network security, not a claim on an external borrower's ability to repay. That's a structurally different risk than crypto-collateral lending or RWA lending, where the yield comes from someone else's credit.

Where this shows up in Rekord

Staked assets are one of the collateral types institutional crypto-backed lending has to price correctly, since a staked position carries lockup and slashing risk on top of ordinary price risk.
