Validators in PoS secure networks by staking tokens, validating blocks, and earning rewards. More stake = higher chances of selection. Risks include slashing and operational costs. Delegation allows indirect participation while keeping “skin in the game.”

The Proof of Stake (PoS) consensus model revolutionized the way blockchain networks operate. Abandoning the energy-intensive logic of Proof of Work (PoW), PoS allows transactions to be validated more sustainably, based on the economic commitment of participants.
One of the central aspects contributing to this change is the figure of the so-called validators, who are central pieces. Understanding how they work is essential for any investor or enthusiast in the crypto universe.
