On March 26, 2026, Filecoin Onchain Cloud (FOC) officially launched on the mainnet, marking a crucial step in Filecoin's transition from a 'decentralized storage network' to a 'programmable on-chain cloud infrastructure.' The ongoing M4.2 milestone (target completion by June 12, 2026, with 61% progress) indicates that this transformation is set to reach its final maturity soon.
A lot of folks are wondering, 'Isn't FOC already live?' The truth is, this reflects the typical phased evolution logic of Web3 projects — the launch of the basic version is just the starting point; the rollout of GA (the official commercial version) is the real key for Filecoin to fully embrace large-scale commercial use.
Why is there an 'Launched but still in progress milestone'?
This is a typical phased release strategy for Web3 projects, with the core distinction being:
▣ Mainnet Beta Version (Current): Address the 'Can it be used?' issue, ensure core functionalities are operational, validate on-chain processes and foundational stability, while collecting early user feedback.
▣ GA Official Version (Production Version): Solve the 'Can it be used at scale?' issue, refine all production-grade details, including performance, security, toolchain, and operational support, allowing enterprise users to confidently deploy critical business operations.
Conclusion: Filecoin's new journey begins with GA
From storage network to on-chain cloud, Filecoin has completed a self-reconstruction over five years, and the GA rollout of FOC is the final battle of this reconstruction.
For Filecoin, FOC signifies much more than just a product upgrade; it's a narrative and value redefinition: it transforms Filecoin from a 'participant in the storage race' into a 'provider of infrastructure for the on-chain cloud era.' When the GA version is officially released in June 2026, Filecoin will no longer be a forgotten 'old project' in the market but a core player in the Web3 and AI era. And we are on the brink of this transformation, witnessing the arrival of a decentralized cloud era.
FOC (Filecoin Onchain Cloud)
This is the core project upgrading the Filecoin network to 'programmable on-chain cloud services,' expanding Filecoin from a mere storage network to an infrastructure supporting on-chain data verification and automated smart contract payments, especially targeting emerging scenarios like AI Agents.
M4.2 Milestone
This is a critical milestone before the official release of FOC (GA), aiming to complete the deployment and verification of the mainnet production environment, allowing developers and users to formally use on-chain cloud services.
Current progress is at 61%, indicating that most core development is complete. Testing, security audits, deployment preparations, and other wrap-up tasks are underway, with full rollout expected by June 12, 2026.
