0 / 5 completed🔷 What is a PoS Validator?
Proof of Stake validators are the backbone of modern blockchains like Ethereum 2.0. Instead of mining with computational power, validators stake cryptocurrency to secure the network and earn rewards.
PoW vs PoS: The Shift
Proof of Work
- •Requires expensive mining hardware
- •Consumes massive electricity (~150 TWh/year)
- •Competition through hash rate
- •Environmental concerns
Proof of Stake
- ✓Standard computer hardware sufficient
- ✓99.95% less energy consumption
- ✓Security through economic stake
- ✓Environmentally sustainable
🎯 Interactive: Validator Roles Explorer
Explore the different duties a PoS validator performs:
Block Proposer
Creates and proposes new blocks to the network
Responsibilities:
- •Gather transactions from mempool
- •Build block with valid state transition
- •Sign block with validator key
- •Broadcast to network
Frequency
Selected pseudo-randomly per slot (~12 seconds)
Reward
~0.05 ETH per block proposed
Why Become a Validator?
Earn Rewards
4-7% APR on staked ETH (varies by network participation)
Secure Network
Help protect the blockchain from attacks and maintain decentralization
Environmental Impact
Support eco-friendly consensus with minimal energy usage
Governance Rights
Participate in protocol decisions and network upgrades
Key Concept: Economic Security
PoS security comes from economic stakes. Validators deposit 32 ETH (~$60,000+) as collateral. Bad behavior results in slashing (losing part of stake), making attacks economically irrational. The more stake, the more secure the network.
