Modular Blockchain
Splitting blockchain jobs into specialized layers. Instead of one chain doing everything, different layers handle execution, data, and consensus.
Example
Celestia handling just data availability while Ethereum handles security, letting rollups be much cheaper.

⚙️How It Works
- 1
Execution Layer
Processes transactions (rollups, app chains)
- 2
Data Availability
Stores transaction data (Celestia, EigenDA)
- 3
Consensus Layer
Agrees on transaction order (Ethereum, validators)
- 4
Settlement Layer
Final security and dispute resolution (Ethereum)
⚖️Monolithic vs Modular
| Feature | monolithic | modular |
|---|---|---|
| Architecture | One chain does all jobs | Specialized layers |
| Examples | Solana, Bitcoin | Ethereum + Celestia |
| Flexibility | Take it or leave it | Mix and match layers |
| Complexity | Simpler | More complex |
