Celestia

Modular Blockchain Architecture

Advanced Track 07
🧩

Blockchain Needs Specialization Too

Bitcoin and Ethereum handle execution, consensus, DA, and settlement all in one layer. Like a factory where one worker does every job — a scalability ceiling is inevitable.

What you'll learn

  • The structural limits of monolithic blockchains and why scaling is hard
  • Modular architecture: separating execution, settlement, consensus, and DA into independent layers
  • How Celestia specializes in consensus+DA while rollups handle execution
🖥️
Execution
Smart contracts run here

Processes transactions and changes state. Rollups take on this layer.

⚖️
Settlement
Dispute resolution, finality

Validates and finalizes rollup outputs. Ethereum is the canonical example.

🗳️
Consensus
Transaction ordering

Determines which transactions are included in a block and in what order.

📦
Data Availability (DA)
Ensuring block data is published

Guarantees that block data is actually published and verifiable by anyone.
