Validator

How it works

A validator stakes collateral to join proof-of-stake consensus, then gets selected to propose new blocks and attest that proposed blocks are valid. On Ethereum a validator requires a 32 ETH deposit; other chains use different minimums and selection logic, but the role is identical: put capital at risk, perform duties honestly, earn rewards.

How it is calculated

Rewards typically split into two components. Consensus rewards are issued by the protocol for successful proposals and attestations, funded by new issuance. Execution rewards, which include priority fees and MEV, are paid by users and block builders and need no new tokens.

The ratio matters. A network paying validators mostly through inflation is subsidizing security at token holders' expense. A network covering validator costs mostly through fees is showing genuine economic demand.

Design consequence

Validator distribution matters as much as token distribution. A network where three operators run 60 percent of validators looks decentralized on the cap table but is operationally centralized. A correlated failure, a shared client bug, a cloud outage, or regulatory pressure on one geographic cluster, can knock those validators offline at once, triggering coordinated penalties and stalling finality.

So validator set diversity is a first-class security metric. Operators with low overhead drift toward concentration unless the protocol rewards minority-client use and caps single-operator stake.
