DA (Lightclient) Nodes
Lumia Chains Approach to Data Availability: DA Lightclients
Lumia chain, being a state-of-the-art Layer 2 scaling solution, recognizes the importance of data availability and has developed its own approach to ensure the integrity and accessibility of transaction data. Lumia chain introduces the concept of DA Lightclients, which form a cluster responsible for storing, verifying and serving the transaction data.
DA Nodes and Node Licenses
To become a DA (lightclient) node operator, participants must acquire a "node license" in the form of a non-fungible token (NFT). These node licenses grant the holders the right to operate a DA node and earn rewards in the form of LUMIA tokens for their services.
Lumia chain with its goal to reach "stage 2" in mind will promote decentralization and community participation. Lumia chain allows "node sale" participants who have purchased a node license NFT to run their own lightclient nodes. By running their node, participants can earn a portion of the LUMIA rewards allocated to the DA nodes cluster.
Technical Details of DA Nodes
The DA nodes in Lumia operates as follows:
Data Storage: When a transaction is processed on the Lumia network, the transaction data is distributed across the DA nodes on AvailDA. Each DA node stores a portion of the data, ensuring that the data is replicated and readily available.
Data Retrieval: When a participant needs to access the transaction data for validation or other purposes, they can request the data from the DA nodes. The DA nodes work together to serve the requested data promptly.
Data Integrity: To ensure the integrity of the stored data, Lumia chain employs cryptographic techniques such as erasure coding and Merkle proofs. These techniques allow for the detection of any data corruption or tampering attempts.
Reward Distribution: The LUMIA rewards allocated to the DA nodes are distributed among the node operators based on their contribution and uptime.
Scalability and Resilience: The DA nodes is designed to scale horizontally, allowing for the addition of more nodes as the network grows. This scalability ensures that the data availability remains high even as the transaction volume increases. Additionally, the distributed nature of the cluster provides resilience against node failures or malicious actors.
Pros and Cons of Lumia chains DA Approach vs. EigenDA
When compared to other data availability solutions like EigenDA, Lumia chains DA approach has its own set of advantages and disadvantages:
Pros:
Community Participation: Lumia chains DA approach allows for greater community participation through the node license NFT system. This promotes decentralization and incentivizes participants to actively contribute to the network's security and performance.
Trusted Partners: By partnering with trusted entities to serve as the initial DA nodes, Lumia chain ensures a high level of reliability and stability in the early stages of the network's development.
Reward Distribution: The DA approach enables a fair distribution of rewards among node operators and node license NFT holders, creating a more inclusive and attractive ecosystem for participants.
Redundancy and Disaster Recovery: Lumia chain will operate both AvailDA as decentralized DA layer but at the same time it will operate centralise DAC. In the event of recovery or disaster chain will switchover from one or the other to serve data and assure chain is operational at all times.
Cons:
Complexity: Lumia chains DA approach introduces additional complexity compared to solutions like EigenDA. Managing the DA nodes cluster, node licenses, and reward distribution requires careful design and implementation. Lumia collaborates with Polygon and GatewayFM to streamline DAC implementation and management.
Conclusion
Lumia chains approach to data availability represents a unique and innovative solution that prioritizes community participation, decentralization, and reward distribution. While it may introduce some complexities compared to other solutions like EigenDA, the approach offers distinct advantages in terms of inclusivity and incentivization as well as promotion of true decentralization.
As Lumia chain continues to refine and optimize its DA nodes, it has the potential to establish itself as a leading example of how data availability can be achieved in a decentralized and community-driven manner. Lumia is currently working on lightclients adjustments to ensure we can run on smarphones as we aim to optimise and decentralize every aspect of the chain.
