Verifiable, Pay-As-You-Go Storage Powered by Filecoin Onchain Cloud
Live site: https://proof-flow.vercel.app/
ProofFlow is a next-generation storage solution built on Filecoin Onchain Cloud, designed to bring the utility model of cloud services into the decentralized world.
With ProofFlow, users and developers can access verifiable storage and retrieval with pay-as-you-go billing, powered by:
- FilecoinWarmStorageService for fast, PDP-verified storage.
- Filecoin Pay for streaming & usage-based payments.
- FilCDN for blazing-fast retrieval.
- Synapse SDK for seamless developer integration.
This transforms Filecoin from a cold archival system into a programmable, on-chain cloud for real-world applications.
Cloud storage today is dominated by centralized providers (AWS, GCP, Azure) with opaque pricing, vendor lock-in, and little verifiability.
In decentralized storage, existing Filecoin solutions:
- Require bulk storage deals, not flexible usage.
- Lack streaming/metered payments for end-users.
- Make retrieval and UX harder for consumer-facing apps.
This leaves a gap: developers and businesses want Filecoin’s trustless storage, but with cloud-like flexibility, pricing, and reliability.
ProofFlow delivers:
-
Pay-As-You-Go Storage
- Users pay only for the data they store/retrieve, billed via Filecoin Pay streaming payments.
-
Verifiable Data Possession
- Integrated PDP checks ensure that storage providers are continuously proving they still hold your data.
-
Blazing-Fast Retrieval
- FilCDN integration delivers cached, high-speed access for end-users.
-
Developer-Friendly SDK
- Plug-and-play with the Synapse SDK — simple APIs for upload, retrieval, and payment flows.
User/App → ProofFlow SDK (Synapse) → FilecoinWarmStorageService + Filecoin Pay
↘ FilCDN (fast retrieval)
↘ PDP Verifier (integrity checks)
- Synapse SDK: simple interface for developers.
- WarmStorage + PDP: ensures fast storage and ongoing proofs.
- Filecoin Pay: streams payments as storage is consumed.
- FilCDN: enables smooth, low-latency retrieval.
- dApps & Games → store user content with metered payments.
- Media Platforms → CDN-level speed for decentralized video streaming.
- Enterprises → verifiable data compliance + transparent pay-as-you-go billing.
- IoT/DePIN apps → devices can store sensor data with micro-payments.
- Unlike existing Filecoin solutions (e.g., Estuary, NFT.storage, etc.), ProofFlow is: ✅ Pay-as-you-go (not bulk, not flat pricing) ✅ Streaming payments (continuous settlement between users & providers) ✅ Cloud-like UX (FilCDN retrieval + SDK ease) ✅ Enterprise-ready (verifiable proofs + transparent billing)
Wave 1 (Product Design)
- Design docs + Notion page (problem, solution, GTM).
- Architecture diagrams & payment flow mockups.
Wave 2 (MVP Build)
- SDK integration with WarmStorage & Filecoin Pay.
- Basic pay-as-you-go storage demo.
Wave 3 (Polish & Iteration)
- FilCDN integration for retrieval.
- Payment dashboards for users & providers.
- PDP monitoring dashboards.
Wave 4 (Final Product)
- Production-ready ProofFlow SDK + Web DApp.
- Live demo: upload, pay-as-you-go usage, instant retrieval.
- FilecoinWarmStorageService (storage + PDP)
- Filecoin Pay (payments: one-time + streaming)
- FilCDN (retrieval acceleration)
- Synapse SDK (developer integration)
- Frontend: React + TypeScript
- Backend: Node.js / Express (for APIs & orchestration)
As we build ProofFlow, we will provide feedback on:
- Payment granularity → support for smaller, micro-metering units.
- SDK DX → simplifying developer integration (examples, docs).
- FilCDN optimization → retrieval SLAs and caching behaviors.
