IPFS Development Services - Decentralized Storage Solutions

IPFS (InterPlanetary File System) is a peer-to-peer protocol for storing and retrieving files. Unlike HTTP (which locates files by server address: http://server.com/file.jpg), IPFS locates files by content hash: ipfs://QmXyz... A CID (Content Identifier) is a cryptographic hash of the file content — the same file always has the same CID regardless of where it's stored. Requesting a CID from IPFS retrieves the content from any node that has it. Content addressing provides: integrity verification (CID proves content is unchanged), deduplication (same file never stored twice), and location independence (content accessible from any IPFS node).

IPFS is the protocol — it defines how files are content-addressed and transferred between peers. IPFS alone doesn't guarantee persistence; nodes only store what they choose to pin. Filecoin is an incentive layer on top of IPFS — it creates a marketplace where clients pay storage providers to keep data available, with cryptographic proofs (Proof-of-Replication, Proof-of-Spacetime) verifying data is stored correctly. For permanent storage: use Filecoin storage deals. For flexible storage with managed pinning: use IPFS with Pinata or Lighthouse pinning services.

Use at least two pinning services for redundancy. Pinata is the most popular — reliable API, generous free tier (1GB), fast gateways, and Pinata's dedicated private gateway provides consistent retrieval performance. Lighthouse provides permanent storage via Filecoin deals and supports token-gated encryption. Filebase is S3-compatible API backed by IPFS, ideal for teams already using AWS S3 tooling. For large collections (10K+ NFTs), we configure dual pinning on Pinata + Lighthouse with Filecoin storage deals for the permanent archive.

IPNS (InterPlanetary Name System) creates mutable pointers to IPFS content — an IPNS name resolves to a CID that can be updated over time. Use IPNS when your application needs a stable reference that points to the latest version of content: dApp frontends (the IPNS name stays the same; the underlying IPFS CID changes with each deployment), user profiles (one IPNS name per user, updated when profile changes), and software distribution (users always download the latest version from a stable IPNS address). Don't use IPNS for NFT tokenURIs — NFT metadata should be immutable.

Slow IPFS retrieval comes from content that isn't cached by popular gateways. Solutions: (1) Use a dedicated gateway (Pinata private gateway, Cloudflare R2 + IPFS) instead of public gateways. (2) Pre-warm content by fetching CIDs through Cloudflare's gateway after upload, getting content cached at edge. (3) Configure multiple gateway URLs with fallback — if Cloudflare is slow, try Pinata gateway. (4) For NFT art, cache IPFS images in your own CDN using the CID as the cache key — serve fast from CDN, verify against IPFS CID for integrity.

Standard ERC-721 metadata JSON: {name: 'Token #1', description: '...', image: 'ipfs://QmImageCID', attributes: [{trait_type: 'Color', value: 'Blue'}, ...]}. The image field should be an IPFS URI (ipfs://QmCID), not an HTTPS URL. Store images first, get their CIDs, then build metadata JSON with image CIDs, then upload metadata JSON and get its CID, then pass metadata CID to smart contract mint function. Never use https:// for NFT artwork — central server NFT artwork breaks when servers go down.

IPFS: content-addressed protocol, persistence requires active pinning, multiple provider options (Pinata, Lighthouse, Filecoin), flexible pricing model. Arweave: pay-once for permanent storage (200+ year endowment model), bundlr/Turbo for easy uploads, popular for Solana NFT metadata and permanent archival. Key difference: Arweave charges upfront for permanence with no ongoing fees; IPFS requires continuous pinning payments. Choose Arweave for set-and-forget NFT metadata; choose IPFS for flexible storage with multiple provider options and IPFS protocol compatibility.

IPFS itself is public — any node that knows a CID can retrieve the content. For private content: encrypt before uploading. Tools: (1) Lighthouse's access control encryption — encrypt with user's wallet signature, decrypt only with authorized wallet. (2) lit-js-sdk (Lit Protocol) — threshold encryption with on-chain access conditions (must hold this NFT to decrypt). (3) Client-side AES-256 encryption before upload — store decryption keys separately from IPFS. The CID references encrypted ciphertext; unauthorized parties get useless bytes.

Filecoin Onchain Cloud (launched January 2026) extends Filecoin beyond pure storage to a full-stack decentralized computing platform — adding compute layers, automated payment channels, and verifiable retrieval proofs. Traditional Filecoin: pay storage providers to hold data, prove via Proof-of-Spacetime. Onchain Cloud: combines storage with computation, allowing AI training jobs or data processing to run on Filecoin infrastructure with on-chain job receipts. Positioned as a decentralized alternative to AWS S3 + EC2 combination for privacy-preserving and censorship-resistant workloads.

We offer support covering: pinning service account management and redundancy monitoring, CID migration if a pinning service changes pricing or shuts down, Filecoin deal renewal before expiry, gateway configuration updates, IPFS library updates as @helia/ipfs and Pinata SDKs evolve, and performance monitoring for IPFS retrieval latency. We also provide content audit services — verifying all production CIDs are still pinned and accessible, before issues affect users.
