1. What is Filecoin Onchain Cloud and what it unlocks
Filecoin's Onchain Cloud (FOC) marks a significant milestone in the evolution of Filecoin, transforming the network from a storage configuration protocol into a programmable, verifiable, and composable on-chain cloud platform.
FOC was first introduced at the Filecoin Developer Summit 5 (FDS-5), building on Filecoin Web Services and formalizing it as a core part of the Filecoin roadmap. It stems from a recurring question in the community: 'What is Filecoin? How can anyone easily leverage it to drive daily application storage needs?'
After five years of growth, the network has expanded significantly, but developers are still seeking simpler ways to leverage Filecoin to meet everyday application storage needs. The development of FOC aims to make Filecoin more user-friendly, flexible, and aligned with the needs of modern Web3 developers and applications. Filecoin Onchain Cloud officially launched on November 18, marking the beginning of a new chapter for the Filecoin network.
Why it is needed and what it can unlock
The core of Filecoin Onchain Cloud (FOC) is transforming Filecoin from a decentralized storage network into a fully programmable on-chain cloud. This is the next step in the network's evolution, thanks to previous upgrades: Filecoin Virtual Machine (FVM), Proof of Data Possession (PDP), and F3 retrieval guarantees. These upgrades unlock the capability to integrate Filecoin's three core markets—storage, retrieval, and computation—into a single layer.
On this basis, FOC provides developers, storage providers, and users with a set of capabilities that meet modern application demands and support new types of services, as follows:
• Composability and integration: FOC supports modular and composable cloud components, allowing developers to combine and reassemble services. (For example: combining Filecoin Warm Storage Service + Filecoin Beam + Filecoin Pay, developers can create a verifiable usage-based backup service with automated scheduling and billing.)
• Flexible payment systems: Tools like Filecoin Pay and SLA-native payment contracts enable service creators to operate revenue-generating services through recurring and stablecoin-based payments (e.g., USDFC). This helps drive a robust, programmable on-chain economy.
• Programmable Cloud Layer: Existing decentralized storage infrastructures often lack programmability and automation capabilities, making it difficult to run or enforce complex workflows or service level guarantees. Filecoin Onchain Cloud (FOC) addresses this issue by transforming Filecoin into a fully programmable on-chain cloud. Developers can deploy modular, verifiable services and support on-chain guarantees, enabling automated storage workflows, service level agreement (SLA)-based protocols, and a composable infrastructure for diverse applications.
• Broader storage utility: Filecoin was initially designed as a cold storage network for archiving data, but modern Web3 applications—such as AI datasets, real-time dApps, and interactive platforms—require fast, warm, and cold storage layers. FOC meets this demand by supporting dynamic access to data while maintaining verifiability.
By supporting new services and economic activities, FOC solidifies Filecoin's position as a programmable cloud for Web3.
How it works: Architecture and core components

Filecoin Onchain Cloud is built on four key layers, abstracting the complexity for developers:
1. Verification Layer
Handling cryptographic guarantees for data storage.
Use proof of data ownership (PDP) to verify secure file storage.
Combined with the payment layer, it achieves verifiable warm storage services.
2. Payment Layer
Managed by a central smart contract called Filecoin Pay.
Supporting one-time and recurring payments using stablecoins like USDFC and other ERC20 tokens.
Payments contingent on proof of storage, ensuring services are delivered on schedule.
3. Service Layer
Providing builders with core FOC functionality and modular services.
Allows the creation of new applications and services utilizing credentials and payment guarantees.
4. Client Layer
Providing developer-friendly interfaces (SDKs, CLIs) for interacting with FOC services.
For example: Synapse SDK, which simplifies integration and workflow automation.
Core services: Building blocks of the on-chain cloud
The core of Filecoin Onchain Cloud begins with five open-source, verifiable, and composable building blocks:
• Filecoin Warm Storage Service - Ensures your data is securely stored and available through proof of data ownership (PDP).
• Filecoin Pay - Supports on-chain payments tied to verifiable service performance, enabling one-time and recurring transactions.
• Filecoin PIP - Bringing IPFS and Filecoin closer than ever for fast, decentralized, and persistent data storage.
• Filecoin Beam - Bridging verifiable data flows between on-chain and off-chain systems.
• Synapse SDK - Provides developers with simple APIs and interfaces to connect and interact with FOC services.
These building blocks form the foundation of a programmable, composable, and verifiable on-chain cloud, enabling developers to create reliable applications with automated guarantees and measurable service performance.
2. Explore use cases for Filecoin's cloud on-chain
Filecoin Onchain Cloud supports a wide range of applications, covering artificial intelligence, autonomous agents, web3 dApps, archival storage, and more. Here are the categories by vertical direction:
Artificial Intelligence and Autonomous Agents
Filecoin Onchain Cloud allows AI and autonomous agents to store models, execute tasks, and automate payments through on-chain proofs. This enables trustless, usage-based workflows that traditional cloud systems cannot provide.
Current integrations and builders:
• Monad: An EVM-based L1 providing low-latency computation, paired with Filecoin Onchain Cloud's verifiable storage for AI model training and deployment.
• ERC-8004: Open-source SDK supporting on-chain AI agents in creating verifiable agent metadata storage.
• Cairn: Rewards repeatable AI research using verifiable storage and Filecoin Pay.
• Groundline: A decentralized knowledge graph database for AI and research teams.
Web3 dApp and frontend
Filecoin Onchain Cloud provides a verifiable foundation for Web3 applications, allowing for on-chain auditing of storage and updates. Frontends can be deployed without centralized servers, controlling the storage, retrieval, and updating of content through smart contracts and on-chain coordination.
Current integrations and builders:
• Ethereum Name Service (ENS) and SAFE: Combining ENS on-chain naming, verifiable storage on Filecoin, and Safe multi-signature governance to create a user-controlled network experience.
• Filosign: An on-chain DocuSign alternative with encrypted electronic signatures.
• Cha-Ching: Rewards developers and AI agents for their verified contributions on GitHub.

Archival, web preservation, and storage services
Filecoin Onchain Cloud provides verifiable storage for archival, web preservation, and large data workloads (such as artificial intelligence and machine learning). Builders can create modular storage services that support programmable payments and storage proofs. FOC supports both cold and warm storage, enabling rapid retrieval through Filecoin Beam and IPFS integration, making higher throughput applications and verifiable data possible.
Current integrations and builders:
• KYVE: A flexible storage solution for chain data from Celestia and Story Protocol, spanning Filecoin providers.

Current integrations and builds
dCipher: Supports fast and secure cross-chain settlement of assets and applications on Filecoin.
Expand potential application scenarios
While early developers primarily focused on AI, Web3 decentralized applications, archival storage, and DePIN networks, we are optimistic about these areas as they showcase the capabilities of FOC. The following examples highlight where FOC can create value, although its potential extends beyond these verticals:
• Enterprise SaaS and compliance platforms: Automated service level agreements (SLAs), verifiable storage of customer data, and scheduled payments in stablecoins.
• Media and content platforms: Providing verifiable access, usage-based payments, and faster retrieval of content.
• Financial services and document workflows: Securely storing records, connecting workflows with verifiable events, and automating payments.
• Data marketplaces and analytics platforms: Selling datasets or APIs with verifiable delivery and automated payment features.
• Hybrid Web 2.5 applications: Integrating verifiable storage and programmable payments into existing applications.
