🧵Filecoin Cloud on Chain: What It Is and Why It Matters In short: Filecoin Cloud on Chain formalizes the storage, retrieval, and payments market as a programmable cloud layer. It introduces modular services such as Warm Storage, Filecoin Pay, Filecoin Pin, Beam, and Synapse SDK. 1/ What is Cloud on Chain? Filecoin Cloud on Chain transforms the network into a programmable cloud layer. It extends Filecoin from proof-of-storage to a complete system where data, payments, and services are executed through contracts that confirm delivery and usage. 2/ Why It Emerges Developers need a direct path from smart contracts to storage, retrieval, and payments. With the maturity of FVM, PDP, and retrieval guarantees, this technology stack can support storage and service logic in one place. 3/ How It Works Cloud on Chain operates on four layers. Proofs are verified through PDP for storage. Payments are settled through Filecoin Pay. Services operate as modular components. Client tools allow developers to interact via the SDK. 4/ Core Building Blocks Warm storage services, Filecoin Pay, Filecoin Pin, @filecoinbeam, and the Synapse SDK form the foundation of the system. Each component is responsible for handling data movement, persistence, or conditional payments. 5/ Storage Utilities @Filecoin was initially a cold storage network. Modern workloads now require warm access and fast retrieval. On-chain cloud supports these layers and associates them with proofs and conditional settlement. 6/ AI and Proxy Use Cases AI models, workflows, and proxy metadata rely on storage that provides proof of ownership and clear payment terms. Projects such as @monad, ERC-8004, Cairn, and Groundline have already connected their data streams to the on-chain cloud stack. 7/ Web3 Decentralized Applications and Front-Ends Applications can deploy front-ends, metadata, and update logic on-chain cloud. @ensdomains, @safe, @Filosign, Cha-Ching, @EastoreWeb3, and @geobrowser utilize proof-of-storage and stable payment processes. 8/ Archiving and Preservation Networks such as @KYVENetwork, @storachanetwork, and Forge rely on Filecoin for storing on-chain data, enterprise datasets, and backup layers in Akave Cloud. Onchain Cloud adds warm storage options, faster retrieval paths via Beam, and tighter IPFS integration. 9/ DePIN Infrastructure DePIN networks can directly anchor mapped data, telemetry data, or settlement records on-chain via Onchain Cloud. This technology stack integrates storage, retrieval, and payment conditions into a single system. @dciphernetwork employs these mechanisms to support the settlement process. 10/ Getting Started Onchain Cloud is currently live on testnet and will launch on mainnet in January 2026. Developers can consult the documentation and materials for Alpha Cohort.
