0 / 5 completed🎓 Key Takeaways
Let's consolidate everything you've learned about Plasma chains, their architecture, security model, and why rollups have become the preferred Layer 2 solution.
🌿
Plasma Fundamentals
- •Child chains process transactions off-chain
- •Merkle roots committed to Ethereum periodically
- •Exit mechanism allows users to withdraw funds
- •Fraud proofs challenge invalid state transitions
- •1,000+ TPS throughput per chain
🔐
Security Model
- •User vigilance required to watch for fraud
- •Data availability depends on operator honesty
- •7-14 day exit challenge period
- •Mass exit problem during high congestion
- •Conditional security based on user actions
⚖️
Trade-offs
- ✓Extremely cheap transactions ($0.001-$0.01)
- ✓Highly scalable throughput
- ✗Data availability burden on users
- ✗Long exit delays for withdrawals
- ✗Complex implementation and exit games
🔄
Plasma vs Rollups
- •Rollups post data to Ethereum, Plasma doesn't
- •Rollups provide unconditional security
- •Plasma cheaper but less practical
- •Rollups dominate production L2 ecosystem
- •Plasma's legacy influenced rollup design
