🪜 Intro
Blockchain architecture defines how the entire Web3 world scales.
But not all blockchains are built the same way.
Some do everything in a single layer — from execution to consensus.
Others divide the work into specialized layers.
That’s where Monolithic vs Modular Blockchain comes in.
Let’s simplify 👇
🧱 Monolithic Blockchain
In a Monolithic blockchain, everything happens in one system:
Execution
Consensus
Data Availability
Settlement
Examples: Bitcoin, Solana
These are like an all-in-one restaurant — fast but limited when the crowd grows.
They offer efficiency, but scalability suffers.
🧩 Modular Blockchain
Now imagine a system where each layer does only what it’s best at.
One layer executes transactions
Another ensures security
Another stores data
This is the Modular approach.
It’s like a restaurant with chefs, waiters, and managers — all working together efficiently.
Examples: Ethereum + Rollups, Celestia, Fuel, EigenLayer
⚙️ L1 vs L2 Connection
Layer 1 (L1) → Base blockchain (Ethereum, Solana, Bitcoin)
Layer 2 (L2) → Built on top to handle execution separately (Arbitrum, Optimism, zkSync)
👉 L1 = Monolithic base
👉 L2 = Modular scaling layer
Together, they make Web3 scalable and affordable.
⚡ Why Modular is the Future
Because it enables:
✅ Scalability without sacrificing security
✅ Customization for different apps
✅ Easy upgrades and innovation
Projects like Celestia, Fuel, Avail, and EigenLayer are leading this modular revolution.
🔮 Conclusion
Monolithic chains laid the foundation.
Modular chains are building the skyscrapers of Web3.
If you’re a developer or builder — think modular, build future.
