In today’s digital-first world, data is one of the most valuable assets we produce. Yet, most of it is stored on centralised servers controlled by a handful of tech giants. Services like Google Drive, AWS, and Microsoft Azure dominate the cloud storage landscape—but with growing concerns over privacy, censorship, and data ownership, a new paradigm is emerging: decentralised storage on blockchain.
Decentralised storage distributes data across a global network of independent nodes, removing reliance on any single authority. This not only enhances security and resilience but also empowers users with true control over their digital content. Among the leading solutions in this space are IPFS, Filecoin, and Arweave—each offering unique approaches to how data is stored, accessed, and preserved.
Let’s explore how these three platforms work, what sets them apart, and which use cases they’re best suited for.
"In a world where data is everything, decentralised storage offers the freedom to own, control, and share your files without the limitations of centralised authorities."
Understanding Decentralised Storage
Decentralised storage replaces traditional server farms with a peer-to-peer network of computers that store encrypted fragments of your data. Instead of uploading a file to a single data center, it's broken into chunks, distributed globally, and secured using cryptography.
This model delivers several key advantages:
- No single point of failure: If one node goes offline, others still hold copies.
- Censorship resistance: No central entity can remove or block your data.
- Enhanced privacy: Files are encrypted and often anonymous by design.
- Cost efficiency: Eliminates recurring subscription fees through innovative economic models.
Compared to centralised storage (like AWS or Dropbox), decentralised systems shift control from corporations to communities—making them ideal for Web3 applications, NFTs, permanent archives, and privacy-conscious users.
IPFS: The Decentralised Web’s File System
The InterPlanetary File System (IPFS) is a protocol designed to make the web faster, safer, and more open. Developed by Protocol Labs, IPFS replaces location-based addressing (e.g., https://server.com/file) with content-based addressing, meaning files are identified by their cryptographic hash rather than where they’re stored.
How IPFS Works
- Chunking: Files are split into smaller blocks.
- Hashing: Each block is assigned a unique cryptographic hash.
- Content Identifier (CID): A root CID is generated from all block hashes, serving as the file’s permanent address.
- Retrieval: When you request a file via its CID, IPFS fetches it from the nearest available node that has the matching hash.
Key Features
- ✅ Content-addressable: Ensures immutability—any change to the file results in a new CID.
- ✅ Deduplication: Identical files are stored only once, saving bandwidth and space.
- ✅ Offline-first capability: You can access content locally if you already have the CID.
Limitations
IPFS does not guarantee long-term persistence. Nodes must manually "pin" files to keep them available. If no one hosts a file, it disappears from the network—making IPFS excellent for distribution but less reliable for permanent storage.

Filecoin: Incentivising Permanent Storage
While IPFS handles how data is addressed and shared, Filecoin solves the who stores it and why. Also developed by Protocol Labs, Filecoin is a decentralised storage marketplace built on top of IPFS, using blockchain to incentivise miners to store data reliably over time.
How Filecoin Works
Filecoin introduces an economic layer where clients pay miners in FIL tokens to store their data. Trust is maintained through cryptographic proofs:
- Proof of Replication (PoRep): Miners prove they’ve stored an exact copy of the client’s data.
- Proof of Spacetime (PoSt): Miners periodically prove they’re still storing the data over time.
- Retrieval Market: Specialised nodes earn FIL by delivering data quickly upon request.
Key Features
- 💼 Market-driven storage: Users choose providers based on price, speed, and reliability.
- 🔐 Incentivisation model: Economic rewards ensure long-term data availability.
- ⚙️ Smart contract integration: Enables automated storage agreements for dApps and DAOs.
Limitations
Running a Filecoin node requires significant hardware resources and technical expertise. This high barrier to entry makes it more suitable for enterprises than individual users.
Arweave: Permanent Data Archiving
Where IPFS enables content distribution and Filecoin offers rentable storage, Arweave takes permanence seriously with its “pay once, store forever” model. It’s designed for use cases where data must never be lost—like historical records, academic research, or NFT metadata.
How Arweave Works
When you upload data to Arweave, you pay a one-time fee in AR tokens. This fee funds an endowment that rewards miners indefinitely for storing your data. Unlike traditional blockchains, Arweave uses a novel structure called the Blockweave, where each new block links not only to the previous one but also to a random earlier block—ensuring continuous verification of old data.
Its consensus mechanism, Succinct Proof of Random Access (SPoRA), requires miners to prove they can retrieve random historical chunks—keeping archival data actively maintained.
Key Features
- 📜 Permaweb: A permanent version of the web where websites and apps live forever.
- 🔄 True immutability: Once written, data cannot be altered or deleted.
- 💸 One-time payment: No recurring fees—ideal for long-term cost savings.
Limitations
Data uploaded to Arweave cannot be edited or removed. While great for archives, this makes it unsuitable for dynamic content. Additionally, its smaller node network means slightly lower decentralisation compared to more established systems.

Choosing the Right Solution
Each platform serves different needs:
| Feature | IPFS | Filecoin | Arweave |
|---|---|---|---|
| Best for | Fast content delivery | Reliable long-term storage | Permanent archiving |
| Incentive Model | None (voluntary hosting) | Pay-as-you-go with FIL | One-time AR payment |
| Data Mutability | Mutable | Mutable | Immutable |
| Ideal Use Cases | DApp frontends, media sharing | Enterprise backups, large datasets | NFTs, legal records, journalism |
Use IPFS when you need fast, censorship-resistant file sharing.
Choose Filecoin for secure, verifiable storage with ongoing access guarantees.
Opt for Arweave when immutability and permanence are non-negotiable.
Frequently Asked Questions (FAQ)
Q: Can I use IPFS without Filecoin?
A: Yes. IPFS works independently as a file-sharing protocol. However, pairing it with Filecoin ensures your files remain accessible long-term.
Q: Is decentralised storage safe from hackers?
A: While no system is 100% immune, decentralised storage significantly reduces risk. Data is encrypted, fragmented, and distributed—making large-scale breaches far harder than with centralised servers.
Q: How much does Arweave cost for permanent storage?
A: Pricing depends on file size. For example, storing 1 GB permanently costs roughly $10–$20 USD (in AR tokens), with no future fees.
Q: Can I delete data from Arweave?
A: No. Arweave is immutable by design—once uploaded, data cannot be altered or removed.
Q: Do I need cryptocurrency to use these platforms?
A: Yes. Filecoin uses FIL and Arweave uses AR tokens for transactions. Some gateways allow fiat payments indirectly.
Q: Are these systems slower than traditional cloud storage?
A: Initial upload/download speeds may vary depending on node availability, but caching and retrieval markets are improving performance rapidly.
