Janction Partners with AltLayer, Enhancing Rollup Technology Support and Driving Joint Marketing Efforts

Tokyo-based blockchain project Janction has partnered with AltLayer to integrate rollup-as-a-service technology into its Layer 2 network, aiming to enhance transaction speeds and reduce costs while expanding ecosystem outreach through joint marketing efforts

The collaboration, first announced in February 2025 and recently highlighted again in September, supports Janction's focus on decentralized AI compute and data traceability, leveraging AltLayer's tools for Ethereum-compatible scaling.

Partnership Announcement and Timeline

Janction, a decentralized physical infrastructure network (DePIN) combined with AI infrastructure, made the partnership public on February 20, 2025, through its official X account. The announcement detailed plans to integrate AltLayer's rollup-as-a-service (RaaS) platform into Janction's Layer 2 blockchain, which operates on the Optimism Superchain stack for Ethereum Virtual Machine (EVM) compatibility. AltLayer followed with a confirmation post, noting the launch of Janction's Layer 2 testnet Phase 1.

The global Janction X account reposted the announcement on September 17, 2025, linking to a Medium article that outlines the technical and promotional aspects of the deal. This timing aligns with Janction's seed funding round, announced in February, and the relaunch of its AI-specialized testnet for expanded infrastructure testing. The partnership builds on Janction's incubation by Jasmy Corporation in 2024, positioning it within Japan's blockchain ecosystem, where Jasmy emphasizes the sovereignty of IoT data.

Janction's Core Infrastructure and Milestones

Janction operates from Minato-ku, Tokyo, under the leadership of CEO Hiroshi Harada, who also serves as Jasmy's Chief Financial Officer. The project develops a permissionless chain for decentralized GPU pools, targeting small and medium-sized enterprises (SMEs) with distributed computing resources

Its Layer 2 solution focuses on AI performance metrics, including cost reduction and cross-chain interoperability, integrated with Jasmy's IoT platform for data monetization and secure device connections.

Key milestones include the 2024 incubation by Jasmy, which laid the foundation for GPU compute and data sovereignty features. In February 2025, the Layer 2 testnet launched with initial Optimism integration, emphasizing AI data traceability. The September 2025 seed round funded further testnet iterations, preparing for mainnet deployment. Additional partnerships announced that month include one with Arichain for cross-chain liquidity and AI/DePIN integration, as well as another with DMC DAO for on-chain music and NFT content handling.

AltLayer's Role in Blockchain Scaling

AltLayer, headquartered in Singapore and led by CEO Jia Yaoqi, provides a protocol for deploying restaked rollups and verifiable agents to support Web3 scaling. Its RaaS platform enables developers to launch application-specific rollups, either optimistic or zero-knowledge (ZK), in minutes, without managing underlying infrastructure. The service supports stacks such as Optimism, Arbitrum, ZKSync, and Polygon CDK, incorporating data availability layers like EigenDA to lower state update costs.

Restaking through EigenLayer forms a core component, allowing shared security across rollups to reduce trust assumptions and enhance fault proofs. AltLayer's ALT token facilitates governance and staking, with a market capitalization exceeding $500 million as of September 2025. Integrations with Chainlink's Cross-Chain Interoperability Protocol (CCIP) enable seamless token transfers, such as those involving Jasmy's JASMY token.

In its first-quarter 2025 recap, AltLayer highlighted Janction's testnet as an example of applying decentralized GPUs to generative AI, with traceable data outputs

Technical Details of the Integration

Under the partnership, Janction incorporates AltLayer's RaaS to deploy a custom rollup on the Optimism Superchain. This setup batches transactions off-chain for settlement on Ethereum, achieving sub-second confirmations through optimized sequencing

EigenLayer's restaking mechanism provides decentralized validation, minimizing centralization risks and supporting modular components, such as temporary centralized sequencers, that can transition to fully decentralized models.

“JANCTION will integrate AltLayer’s RaaS into its Layer2 blockchain to provide a flexible and high-performance scaling solution. This partnership will enable JANCTION to build an Ethereum-compatible Rollup chain, achieving faster transaction processing, lower fees, and improved interoperability. Additionally, by utilizing AltLayer’s EigenLayer for shared security, operations can be conducted in a secure and decentralized environment,” Janction Medium Post read

Data availability relies on EigenDA, which cuts calldata expenses by more than 90 percent compared to traditional methods. The integration maintains EVM compatibility, allowing the use of standard development tools and canonical bridge contracts for multi-chain applications. Interoperability extends to bridging protocols and chains, facilitating connections between Janction's AI-focused features and broader ecosystems.

Security measures include restaked validators for dispute resolution, ensuring operations in a decentralized environment. Deployment times shrink from weeks or months to minutes, as RaaS handles infrastructure setup. This configuration supports Janction's goals for traceable AI data, where computations on decentralized GPUs can be verified without isolated validation silos.

Joint Marketing and Ecosystem Strategies

Beyond technical support, the agreement includes collaborative marketing efforts aimed at targeting developers and enterprises. Both parties will utilize their respective networks for co-branded campaigns and events. This aims to broaden exposure for AI and Web3 applications, drawing in builders for use cases like verifiable AI agents.

The partnership also addresses blockchain interoperability by combining assets to enable seamless connections across chains and protocols. Developers can integrate Janction's GPU resources with external systems, supporting applications in non-fungible tokens (NFTs) and Web3 gaming through low-cost minting and rendering. In decentralized finance (DeFi) and real-world asset (RWA) tokenization, it aids cross-chain liquidity for AI-derived assets. For AI agents, the setup verifies computations on distributed hardware.

Janction's ecosystem ties extend to real-world applications via partners like Aplix, a Tokyo Stock Exchange-listed company, for digital IDs, environmental, social, and governance (ESG) carbon credits, and payment processing. Recent Chainlink CCIP integration with Jasmy allows cross-chain JASMY transfers, complementing the rollup enhancements.

Conclusion

The Janction-AltLayer partnership provides a structured foundation for integrating rollup-as-a-service into Janction's Layer 2 blockchain, enabling Ethereum-compatible scaling with features like sub-second transaction confirmations, fee reductions through EigenDA, and shared security via EigenLayer restaking

These elements support Janction's decentralized GPU compute and AI data traceability objectives, while joint marketing efforts expand developer and enterprise engagement

For Janction, this collaboration marks a key step in establishing its position within the blockchain industry, particularly in Japan's IoT and Web3 sectors, by leveraging AltLayer's established RaaS infrastructure to address scalability challenges in AI-driven applications.
