Lumia chain is a Layer 2 solution with rollup as its core, The architecture of Lumia is designed to maximize capital efficiency, liquidity, and interoperability while providing a seamless user experience.
the architecture of Lumia represents a significant leap forward in the realm of roll-up blockchain platforms. By combining the power of Polygon CDK, Lumia Stream, AvailDA, Polygon AggLayer, Chain and Account Abstraction, decentralized sequencers, decentralized zkProvers and custom AVS', Lumia delivers a highly scalable, interoperable, and user-friendly ecosystem that empowers developers and users to unlock the full potential of decentralized technologies.
At the core of Lumia's architecture lies the Polygon CDK (Chain Development Kit), which enables the creation of custom blockchain networks tailored to specific use cases. The Polygon CDK allows Lumia to incorporate various execution environments, such as Privado ID and Miden providing developers with the flexibility to build and deploy a wide range of decentralized applications (dApps).
One of the key components of Lumia is the Lumia Stream, a native liquidity module that aggregates liquidity from both centralized exchanges (CEXs) and decentralized exchanges (DEXs). This unified liquidity pool enables developers to focus on building innovative dApps without worrying about attracting sufficient liquidity. Lumia Stream ensures that users have access to deep liquidity across various assets, enhancing the overall trading experience and facilitating efficient market-making.
To further enhance scalability and interoperability, Lumia integrates with two cutting-edge solutions: AvailDA and Polygon AggLayer. AvailDA is a next-gen decentralized data availability solution that ensures the availability and integrity of transaction data off-chain, reducing the burden on the main Ethereum blockchain. By leveraging AvailDA, Lumia can achieve higher throughput and lower transaction costs while maintaining the security guarantees of the underlying blockchain.
Lumia also incorporates advanced features such as Account Abstraction with Chain Abstraction, which simplifies the user experience by abstracting away the complexities of private key management. Chain abstraction coupled with account abstraction, users can interact with dApps using familiar authentication methods, such as email or social media accounts, without compromising the security of their assets.
To ensure the security and decentralization of the network, Lumia is currently in transition phase to decentralize its sequencers. Sequencers are responsible for ordering and processing transactions, and by distributing this role across multiple nodes, Lumia eliminates single points of failure and enhances the resilience of the network. The decentralized sequencer network also contributes to fast finality, allowing transactions to be confirmed quickly and irreversibly. Sequencer network is currently in development and will be readily available Q2-2025.
In addition to the core components, Lumia integrates with custom AVS (Actively Validated Services), which provide additional security and validation capabilities. First AVS service to go live on Lumia will be TheRadius. The AVS system will allow us to tap into blockspace network to protect Lumia users from MEV .
