Let's explore the foundational technology and architectural principles that drive Glue Blockchain. Understanding the reasons behind Glue's choice of technology, its unique approach to Layer 1 and Layer 2 integration, and how it manages cross-chain communication is crucial for grasping the full potential of the platform.
Through a series of FAQs, we address key questions about Glue’s core infrastructure, offering insights into why certain decisions were made and how they contribute to the overall performance and scalability of the ecosystem.
What is the core technology behind Glue?
Glue is built on Substrate, a framework developed by Polkadot. Substrate is open-source and renowned for its robust performance and scalability, making it an ideal choice for Glue’s requirements.
Why Substrate?
The selection of Substrate was based on its ability to handle security efficiently on Layer 1 (L1) while enabling a highly scalable and customizable execution environment on Layer 2 (L2).
This separation of concerns enhances the overall performance and flexibility of the Glue network. In essence, Substrate’s architecture allows Glue to maintain a lean L1 focused solely on security, while delegating execution tasks, including smart contracts, to specialized L2 environments.
How does Glue handle different use cases and needs?
Glue’s strategy involves clustering use cases with similar requirements onto a single, use-case optimized L2 chain. This method ensures that applications with compatible needs, such as those requiring high decentralization or low transaction latency, are grouped together.
By doing so, Glue provides a more efficient and effective platform while avoiding the pitfalls of having a single chain for each application.
How does Glue’s architecture differ from traditional Layer 1 and Layer 2?
Glue’s architecture introduces a significant innovation by segregating security and execution between L1 and L2 layers.
The L1 in Glue is dedicated exclusively to ensuring security and validating blocks produced by various L2s. It does not handle smart contracts or other complex tasks, which are instead managed by L2s.
This separation allows the L1 to operate more efficiently, focusing solely on token transfers and staking for validation. The L2s, on the other hand, handle smart contracts and other execution tasks, with each L2 tailored for specific use cases such as finance or gaming.
What is the main advantage of Glue’s approach to Layer 1 and L2s?
The main advantage of Glu’s approach is that security is focused on L1, while censorship resistance can be tailored and optimized on L2.
In simple terms, how will L2s communicate with each other on Glue?
Glue uses a protocol called Cross-Chain Messaging (XCM) to facilitate communication between Layer 2 (L2) chains. Unlike Ethereum, where inter-chain messaging often requires oracles or bridges, Glue's L2s are directly connected through a native relay chain.
This setup allows messages to be passed seamlessly, including executing smart contracts across different L2s. The system ensures that messages are reliably executed, enhancing cross-chain composability.
Does Glue connect with other blockchains?
Yes, Glue is integrating with LayerZero to create a canonical bridge that will connect Glue to other blockchain networks. This integration aims to enhance interoperability across different ecosystems, allowing Glue users to interact with a broader range of blockchains seamlessly.
