You've completed the PoS Validator module! Here's a summary of what you've learned about Proof of Stake validation and staking.
🔷
Validator Basics
- •32 ETH stake required per validator
- •Replaces energy-intensive PoW mining
- •99.95% less energy than Bitcoin
- •Four main roles: proposer, attester, aggregator, sync
⏰
Timing & Process
- •12-second slots for block proposals
- •32 slots = 1 epoch (6.4 minutes)
- •Finality after 2 epochs (~12.8 min)
- •Pseudo-random duty assignments
💰
Rewards Structure
- •4-7% APR on staked ETH
- •Attestations: ~0.0001 ETH each
- •Block proposals: ~0.05 ETH bonus
- •MEV can significantly boost returns
⚠️
Penalties & Slashing
- •Downtime reduces rewards proportionally
- •Double-signing: Slashed 0.5-1+ ETH
- •Surround votes: Up to 16 ETH loss
- •Slashed validators forcefully exited
Quick Reference
| Metric | Value | Notes |
|---|---|---|
| Stake Requirement | 32 ETH | Per validator node |
| Slot Duration | 12 seconds | One block proposal opportunity |
| Epoch Duration | 6.4 minutes | 32 slots |
| Finality Time | ~12.8 minutes | 2 epochs with 2/3+ support |
| Annual Yield | 4-7% APR | Depends on network participation |
| Slashing Penalty | 0.5-16 ETH | Based on offense severity |
