Validator

consensus
staking

A consensus participant that proposes, verifies, or attests to blocks, often after bonding stake in a proof-of-stake network.

1
definition

A validator runs software that participates in consensus by checking blocks, voting or attesting, and sometimes proposing new blocks. In proof-of-stake systems, validators usually lock collateral that can earn rewards or be penalized.

2
risks

Validators must stay online, follow protocol rules, and protect signing keys. Downtime can reduce rewards, while serious misbehavior such as double-signing can trigger slashing on networks that support it.
