What is Modular Blockchain?
Modular blockchains are amazing, right? You’ve probably heard about them from a friend or on Twitter. Now you’re wondering: What exactly is a modular blockchain?
A modular blockchain is a specialized blockchain that focuses on performing one or two specific tasks, unlike monolithic blockchains that handle everything themselves. Instead of operating independently, multiple modular chains combine to form a modular stack, where each blockchain specializes in a particular function.
Think of modular blockchains like Lego pieces—you can mix and match them to create different blockchain architectures. Celestia is a prime example of a modular blockchain that provides core functions such as consensus and data availability, while rollups handle execution.
Why is modular an improvement?
Modular blockchains solve several challenges faced by monolithic blockchains:
- More flexibility: Developers can build anything they want with fewer restrictions.
- Lower costs: Celestia’s data availability sampling ensures that applications remain affordable for users.
- Greater accessibility: Technologies like fraud proofs and validity proofs allow anyone to verify the blockchain efficiently.
By dividing responsibilities, modular blockchains create a more scalable and customizable system.
What is Celestia?
Celestia is a blockchain network that adopts a modular approach, aiming to address scalability issues commonly found in traditional blockchain systems. Unlike monolithic blockchains that bundle execution, consensus, and data availability together, Celestia separates execution from consensus and implements data availability sampling (DAS) as a core feature. This allows rollups and Layer 2 solutions to build on top of Celestia while leveraging its robust consensus and data availability layers.
How Does Celestia Work?
Celestia’s approach to scalability includes:
- Modular Design: By dividing execution and consensus, Celestia allows for more flexibility, scalability, and specialization across different blockchain layers.
- Data Availability Sampling (DAS): A core feature that enables nodes to verify only the necessary portions of transaction data, reducing network load and enhancing efficiency.
- Security & Resource Efficiency: Celestia employs fraud proofs and validity proofs, ensuring that light nodes can verify the blockchain with security comparable to full nodes but using significantly fewer resources.
- Architecture: Celestia’s design aligns with scalable and decentralized protocols, supporting a high volume of users without compromising decentralization or security.
Key Features of Celestia
- Scalability: Celestia’s modular approach ensures high-throughput data availability (DA) that scales as more users join.
- Customizability: Developers can launch their own blockchain without setting up a validator network.
- Efficiency: Rollups publish transaction data on Celestia, allowing anyone to verify it easily with a light node.
By unbundling the blockchain stack, Celestia enables innovation in blockchain architecture while maintaining decentralization and security.
