Tokyo-based blockchain project Janction has entered a strategic partnership with Singapore’s AltLayer to integrate rollup-as-a-service technology into its Layer-2 network. The collaboration aims to improve transaction throughput, lower costs, and expand visibility through coordinated marketing efforts. It also supports Janction’s broader goals of powering decentralized GPU compute and enabling AI data traceability on-chain.
Partnership Details and Timeline
Janction publicly revealed the partnership on February 20, 2025, confirming plans to incorporate AltLayer’s rollup-as-a-service (RaaS) platform into its Layer-2 chain built on the Optimism Superchain. AltLayer later followed with its own announcement, highlighting Janction’s Phase 1 testnet launch.
The partnership resurfaced in the spotlight in September 2025, when Janction’s global account amplified the news alongside a detailed Medium article outlining technical plans and promotional initiatives. The renewed visibility coincided with Janction’s latest seed funding round and the relaunch of its AI-focused testnet environment.
Janction, incubated by Jasmy Corporation in 2024, positions itself within Japan’s expanding Web3 and IoT landscape by emphasizing personal data sovereignty and decentralized infrastructure.
Janction's Infrastructure Focus
Led by CEO Hiroshi Harada, Janction is building a permissionless chain designed for decentralized GPU pools—an increasingly important resource for AI workloads. The network is geared toward SMEs that require cost-efficient, distributed computing.
Key components of Janction’s roadmap include:
- •Ethereum-compatible Layer-2 scaling on the Optimism Superchain
- •AI compute verification and data traceability
- •Integration with Jasmy’s IoT suite for secure data flow and monetization
- •Cross-chain functionality for NFTs, RWA tokenization, and DeFi liquidity
Additional partnerships announced in September include Arichain (for cross-chain liquidity and AI/DePIN collaboration) and DMC DAO (for on-chain music and NFT content).
AltLayer's Rollup-as-a-Service Capabilities
AltLayer specializes in deploying fast, modular rollups for Web3 applications, supporting stacks such as Optimism, Arbitrum, Polygon CDK, ZKSync, and others. Its system uses EigenDA for data availability and EigenLayer restaking for shared security, reducing state update costs and improving reliability.
For Janction, the integration brings:
- •Sub-second transaction confirmation
- •90% reduction in calldata costs through EigenDA
- •EVM-compatibility for easy developer migration
- •Shared security through EigenLayer validators
- •Rapid rollup deployment in minutes instead of months
AltLayer’s native token, ALT, is used for governance and staking.
Collaborative Outreach and Ecosystem Links
Beyond the technical integration, the two teams will collaborate on marketing, events, and developer initiatives aimed at expanding adoption of AI-enabled Web3 tools.
This includes outreach to builders in:
- •AI and decentralized GPU compute
- •Web3 gaming and NFT rendering
- •Cross-chain liquidity and DeFi
- •ESG carbon markets and digital ID solutions
Janction is already linked with Japan-listed Aplix, enabling integrations in digital identity, sustainability tracking, and payments.
Conclusion
The Janction–AltLayer partnership establishes a robust foundation for scaling Janction’s Layer-2 network with enterprise-grade rollup infrastructure. By combining sub-second rollup performance, lower fees through EigenDA, and shared security via EigenLayer, the collaboration strengthens Janction’s mission of delivering decentralized GPU compute and verifiable AI workflows.
With aligned marketing efforts and cross-chain integrations, Janction is positioning itself as a notable player in Japan’s emerging AI-Web3 sector—while leveraging AltLayer’s proven RaaS technology to accelerate its path to mainnet.
