Validator of PoS
Network participants staking tokens to propose and attest blocks in proof-of-stake consensus.
What is Validator of PoS?
In PoS, validators stake 32 ETH ($130,000 at $4,000/ETH) to run nodes, proposing blocks every 12 seconds and attesting via committees—Ethereum’s 1 million validators secure $400 billion. Selection is pseudorandom, weighted by stake, slashing 1-100% for downtime/malice.
Solana validators (2,000+) stake SOL for 1,500 TPS, earning 6% APY minus 8% commission, requiring 128 GB RAM setups. Cardano’s Ouroboros selects via stake pools, processing 250 TPS.
Energy-efficient (99% less than PoW), PoS validators earn $10 billion yearly rewards, but centralization risks (top 1% control 33% stake) prompt delegation tools.
