In the rapidly evolving landscape of Web3, the integration of advanced data solutions is pivotal for platforms like Nexus, a Zero-Knowledge Virtual Machine (zkVM) platform dedicated to building the "Verifiable Internet." This survey note explores how Orochi Network’s zkDA Layers and zkDatabase can enhance Nexus’s capabilities, addressing critical data-related challenges and outlining areas for future improvement. The analysis is grounded in the provided details and supplemented by insights into the projects’ real-world context, ensuring a comprehensive understanding for professionals in the Web3 space.
1. What is Nexus?
Nexus is a pioneering Web3 platform that built a world supercomputer by leveraging the latest advancements in cryptography, engineering, and science. Nexus Zero-Knowledge Virtual Machine (zkVM) is a main component of Nexus that provides verifiable computation. Nexus leveraged zero-knowledge proofs (ZKPs) to secure and scale its infrastructure, and ZKPs properties help to guarantee that the infrastructure is secure and verifiable cryptographically. This approach builds up the future of the verifiable internet.

Nexus, zkVM and Nexus Network enable developers to create scalable, privacy-preserving decentralized applications (dApps/zkApps) with provable computation. Its mission aligns with the growing demand for verifiable and secure computing infrastructures in Web3. However, like many platforms, Nexus faces challenges related to data availability and integrity, which are exacerbated by the limitations of current Data Availability Layers (DA Layers) such as Celestia and EigenDA.
These limitations include synchronous systems causing delays, single commitment schemes restricting compatibility, lack of native Zero-Knowledge Proof (ZKP) support, and an inability to prove data integrity. Orochi Network, identified as a Verifiable Data Infrastructure provider, offers solutions through its zkDA Layers and zkDatabase, which are designed to address these pain points.
2. What is the Problem?
2.1 How Orochi Solves the Problem for Nexus
Data Availability: Orochi’s zkDA Layer stores data off-chain, ensuring availability with distributed storage based on Merkle DAG.
Data Integrity: ZK-data-rollups provide succinct proofs, ensuring data integrity and verifiability. They address the lack of native ZKP support in traditional DA Layers (Data Availability Layers) and the cost of data verification. Meanwhile, the Verifiable Data Pipeline proves every step of data processing from its source and undergoing to its consumer, maintaining the verifiable data authenticity.
Adaptability: zkDatabase guarantees a seamless experience when migrating from a traditional Database Management System (DBMS) to ZKP and cryptographic databases.

2.2 zkDatabase & zkDA Layer Terminating Oracle Market
Traditional oracles, which feed external data (e.g., stock prices, weather) to smart contracts, often rely on centralized systems, introducing trust issues and vulnerabilities like data manipulation. Orochi’s zkDA Layers and zkDatabase are poised to disrupt this market by offering a decentralized, verifiable alternative:
Data Provisioning: zkDA Layers stores data off-chain on its own distributed storage with proof of data integrity in ZKPs, eliminating centralized points of failure. Nexus dApps/zkApps can access real-time data—like market feeds—without relying on centralized oracles.
Data Integrity: zkDatabase provides verifiable data queries with ZKP-backed assurances of correctness, enhancing security and scalability for Nexus.
Friendly SDK: The SDK provides a seamless experience to developers by employing noSQL and ODM. SDK handles all complex tasks to simplify the interaction with ZK circuits.
3. Conclusion
Orochi Network’s zkDA Layers and zkDatabase is an extra layer that provides verifiable data for Nexus, shattering the barriers of data availability, integrity, and developer efficiency in Web3. By tackling the flaws of traditional DA Layers and joining Nexus powers the "Verifiable Internet", Orochi Network delivers a future where trustless, scalable innovation isn’t a dream—it’s reality, so here are the benefits when joining the Orochi Ecosystem:
Orochi’s focus on Zero-Knowledge Proofs (ZKPs) and Multi-party Computation positions it as a leader in addressing data integrity and privacy challenges, particularly for decentralized applications (dApps/zkApps) and AI/ML. Supported by the Ethereum Foundation, zkMemory is well-positioned to deliver the zkVM framework.
