Overview

Optopia.ai, as the name suggests, distinguishes itself from other Ethereum Layer 2 networks by prioritizing innovative AI standards and exploring AI application scenarios. Optopia is designed as an L2 blockchain specifically tailored for Artificial Intelligence (AI) applications. Our objective is to pioneer AI application standards and explore diverse AI use cases. We aim to deliver exceptional performance, minimal costs, and robust security for AI applications deployed on Optopia, thereby driving the advancement and practical implementation of AI technology. Undoubtedly, this sets higher standards for Optopia's technological realization, especially in terms of the security and reliability of the data availability layer.

Data availability is a crucial concept in Rollup, ensuring that block producers promptly publish the transaction data of their blocks in the data availability layer. This enables network participants to download and access these data blocks, thereby verifying their authenticity. With the introduction of the Ethereum Cancun upgrade (also known as EIP-4844), the scalability of Ethereum has significantly improved. This upgrade has introduced Proto-Danksharding, a method that reduces transaction costs and enhances transaction throughput. Consequently, second-layer Rollups can directly publish transaction data on Ethereum, reducing reliance on third-party data availability (DA) layers. Within a controllable cost range, this ensures the credibility of transactions.

Optopia inherits the widely used Ethereum data availability module, which stores transaction data and ensures that all data is accessible to nodes on both Layer-1 (such as Ethereum) and Layer-2 (such as Optopia) networks. However, its native provision only offers 18 days of accessibility, significantly limiting Optopia's network in terms of long-term data access requirements. Therefore, a set of technology implementation standards that can achieve long-term, secure, and accessible data availability (DA) Layer is urgently needed. This is where the Arweave Blob Archiver comes into play.

Technical Background

The technical approach of Arweave Blob Archiver, as compared to alternative digital asset management solutions on Ethereum (such as Celestia, Avail, and EigenDA), achieves long-term storage capability by integrating with the Ethereum ecosystem through Arweave integration. For instance, while Celestia retains data for 1-3 months, EigenDA retains data for only 14 days.

The Arweave Blob Archiver consists of two main components:

1. Storage Contract Deployed on Ethereum Layer-1: Responsible for on-chain fee allocation and storage verification.

2. Layer-2 Storage Network Composed of Nodes: Responsible for Arweave data storage replicas and continuous data availability sampling verification.

The working mechanism of the Arweave Blob Archiver involves the following steps:

1. Extract Mainnet Transaction Data: Extract transaction data from the Ethereum mainnet.

2. Store Blobs on Arweave: Store a Blob corresponding to each block on the Arweave network to ensure data backup.

3. Tagging for Correspondence: When storing data on Arweave, Optopia adds tags associated with the mainnet block height. These tags facilitate easy retrieval of specific block information through the Arweave browser, providing evidence of backed-up transaction records on the Arweave network.

Benefits and Future Prospects

It's clear that Optopia has significantly benefited from implementing the technical approach of Arweave Blob Archiver. This integration has not only bolstered data security but has also introduced new possibilities for distributed control and scalability within the Optopia ecosystem.

The innovative integration enables all artificial intelligence applications within the Optopia ecosystem to permanently access and store transaction data, thereby enhancing network security and reliability, and bringing numerous benefits to Optopia. This forward-thinking approach has paved the way for establishing a stronger and more scalable Optopia ecosystem.

Key features of the Arweave Blob Archiver include:

• Enhanced Security: Ensures reliable security, making all data available to nodes and minimizing the possibility of malicious activity.

• Distributed Control and Scalability: By combining the data availability layer with Arweave backups, Optopia rollups gain unique advantages.

• Significant Cost Reduction: EIP-4844 significantly reduces the cost of the Ethereum DA module, leveraging Arweave backup data for long-term storage capability.

• Effortless Settlement and Verification Proof: The Arweave Blob Archiver ensures 24/7 data availability across all layers of Optopia, aiding dispute resolution and fraud prevention.

The implementation of Arweave Blob Archiver is indeed a pivotal measure in ensuring the perpetual availability and security of data. This innovative integration not only enhances Optopia's technical capabilities but also lays the foundation for future improvements in data integrity and network reliability. Optopia aims for this technical approach to truly lead the development of data availability solutions, setting new standards for excellence and innovation.

Lastly, it is worth noting that this solution is supported by 4EVERLAND's Perma Blob Archiver service, further enhancing the technical strength and reliability of Optopia's infrastructure. If you seek detailed technical specifications, please refer to the provided article for further information.
