Scaling Challenges
Blockchain networks face scalability challenges due to the need for all nodes to process every transaction. Layer 2 solutions address this by processing transactions off the main chain.
Layer 2 Solutions
- State Channels: Off-chain transaction processing
- Rollups: Batch multiple transactions together
- Sidechains: Independent chains with bridge connections
- Plasma: Hierarchical blockchain structure
- Optimistic Rollups: Assume validity, challenge if needed
