Definition

A node that verifies and approves transactions in Proof of Stake networks

Validators in networks like Solana must stake a minimum amount and face slashing penalties for misconduct, aligning incentives with honest behavior. Validator Stats (2025): Ethereum: 1 million+ validators. Solana: 2,000+ active. Slashing Rate: <0.01% annually. Requirements: Hardware: 16-core CPU, 128GB RAM; Uptime: 99%+ to avoid penalties.
