How Luntra Works

Architecture Overview

Luntra's architecture signifies a pivotal advancement in blockchain design, effectively merging artificial intelligence with established blockchain infrastructure. Luntra, constructed upon the foundation of Ethereum's OP Stack, enhances conventional Layer 2 functionalities by incorporating native AI integration throughout all layers.

Architecture Components

User Interface Layer

User Wallet (EIP-4337 Smart Accounts) The EIP-4337 smart account abstraction establishes a fundamental framework for user interactions, while the Paymaster+ functionality provides additional enhancements to this system. This methodology alleviates the complexities associated with the administration of conventional private keys while simultaneously facilitating sponsored transactions and providing adaptable mechanisms for fee payment. Individuals can interact with the network via established interfaces, simultaneously benefiting from advanced account programmability.

Sequencer Node (OP-Stack + AI Middleware) The foundational orchestration layer synthesizes Optimism's proven rollup technology with customized AI middleware. This integrated methodology allows the sequencer to optimize the sequencing of transactions, safeguard against miner extractable value (MEV), and efficiently allocate resources, all while maintaining compatibility with current Ethereum tools and frameworks.

AI Intelligence Layer

The AI Intelligence Layer functions as the pivotal cognitive element within the Luntra ecosystem, comprising five distinct AI modules that work in concert to provide comprehensive blockchain intelligence.

ChainSage—Wallet Intelligence ChainSage utilizes Natural Language Processing (NLP) and Graph Neural Networks (GNN) to examine transaction patterns and provide users with valuable insights. This tool converts intricate blockchain processes into comprehensible summaries, allowing users to grasp the consequences of their transactions prior to execution.

MEV Radar—Protection System MEV Radar is developed utilizing PyTorch and sophisticated graph neural network architectures, monitoring transaction pools and block construction to identify and mitigate Maximal Extractable Value (MEV) attacks.

Paymaster+—Smart Fee Management It systematically allocates transaction fees in accordance with user behavior patterns and risk profiles, while facilitating a range of payment methods, including alternative tokens and deferred payment arrangements.

VerifyX—ZK Identity Verification VerifyX offers identity verification utilizing zero-knowledge proof methodologies, ensuring that user privacy remains intact. This mechanism facilitates the targeted sharing of credentials and upholds a reputation framework that bolsters security while safeguarding anonymity.

AgentX—Autonomous Agents AgentX represents the pinnacle of technological advancement, employing LangChain frameworks alongside zero-knowledge machine learning (zkML) to develop intelligent agents capable of executing intricate plans on behalf of users. These agents possess the capability to adjust to market dynamics and perform complex operations, all while ensuring total transparency via zero-knowledge proofs.

Execution Environment

EVM Execution Layer The enhanced Ethereum Virtual Machine maintains full compatibility with existing smart contracts while providing AI-hookable interfaces. This allows AI modules to interact with contract execution in real-time, enabling intelligent optimizations and automated decision-making during transaction processing.

AI Runtime Engine The runtime engine provides the computational infrastructure for AI operations, utilizing LangChain orchestration with PyTorch backends. This hot-swappable MLOps infrastructure enables dynamic model updates and A/B testing of AI strategies without network downtime.

Blob Submitter Implementing EIP-4844 blob transactions, the blob submitter efficiently uploads AI models and large datasets to Ethereum's data availability layer. This component serves as a link between high-throughput AI operations and Ethereum's security guarantees.

Data & Storage Layer

Blob Layer—Model Storage The blob layer utilizes Ethereum's data availability infrastructure to store AI models in approximately 125 KB chunks. This approach ensures models remain accessible and verifiable while leveraging Ethereum's consensus mechanism for data integrity.

Beacon Chain Data Availability Models and associated data benefit from Ethereum's beacon chain chainsystem for data availability with approximately two weeks of guaranteed retention. This provides sufficient time for verification and dispute resolution while maintaining cost efficiency.

Model Registry The smart contract-based model registry manages metadata, licensing, and access controls for AI models. It implements sophisticated licensing engines that enable flexible monetization strategies for AI model creators while ensuring proper attribution and usage tracking.

Zero-Knowledge Layer

Dispute Resolution Mechanism The hybrid rollup architecture includes an intelligent dispute trigger system that determines when zero-knowledge proof generation is necessary. This selective approach optimizes for performance while maintaining security guarantees.

Halo2 Proof System When disputes arise, the system employs Halo2-based ZK-SNARK generation to create cryptographic proofs of computation integrity. This feature ensures that all AI operations can be independently verified without revealing sensitive model parameters or user data.

Proof of Integrity: The last part provides robust security checks that confirm all AI tasks were performed correctly, enabling individuals to verify complex machine learning processes without relying on trust.

External Integrations

On-Chain AI Marketplace

Developer Model Deployment: Developers can deploy AI models directly to the network through the blob submission system. The marketplace provides tools for model optimization, testing, and deployment while ensuring compliance with licensing requirements.

User Model Acquisition Users can discover, purchase, and verify AI models through the integrated marketplace. The system supports various payment methods and licensing models, from one-time purchases to usage-based subscriptions.

Supporting Infrastructure

Web Dashboard A comprehensive web application provides real-time monitoring, analytics, and management capabilities for all ecosystem participants. The dashboard aggregates data from across the architecture to provide actionable insights.

Vector Database Semantic model search features help users quickly find the right AI models by looking at their functions, performance, and compatibility.

Continuous Learning Engine The self-learning engine continuously improves AI model performance by analyzing usage patterns, user feedback, and market conditions. This approach creates a feedback loop that enhances the entire ecosystem over time.
