Filecoin is a decentralized storage market built by Protocol Labs, tightly bound to the IPFS protocol. Visit the Binance Official Site to check FIL's spot price, download the Official Binance App, and iPhone users should check the Download Page first. The short answer: Filecoin dwarfs Arweave in raw data scale (18 EB vs. 250 TB — a gap of over 70,000x), but charges a lower price per GB by billing on a recurring basis; Arweave's pitch is "permanent storage," while Filecoin's pitch is "storage at massive, recurring scale." As of April 2026, FIL's market cap is around $3.5 billion, making it the largest project in the decentralized storage sector.
Filecoin was founded by Juan Benet, who also invented the IPFS (InterPlanetary File System) protocol. Protocol Labs is the research organization behind IPFS, Filecoin, libp2p, and several other open-source projects, headquartered in San Francisco.
Filecoin raised a record-setting $257 million in its 2017 ICO, and its mainnet launched in October 2020. FIL's price spiked as high as $200 shortly after launch, with a peak market cap of $38 billion, before a major pullback. FIL currently trades around $5, with a market cap of $3.5 billion.
IPFS is a distributed file protocol based on content addressing. Files are addressed by their hash (a CID), and nodes transfer them peer-to-peer. IPFS itself has no incentive layer — nodes store files voluntarily, with no payment involved.
Filecoin is the incentive layer for IPFS. It defines a mechanism: a client pays to request storage → a miner takes on the storage obligation and periodically generates proof of storage → the miner earns FIL rewards. Filecoin is what makes IPFS storage commercially viable and scalable.
| Dimension | IPFS | Filecoin |
|---|---|---|
| Protocol layer | File transfer | Economic incentives |
| Payment required | No | Yes |
| Data persistence | Not guaranteed (nodes can delete) | Guaranteed (for the contract term) |
| Storage proof mechanism | None | PoSt (Proof of Spacetime) |
| Primary customers | Any IPFS application | Large-scale data storage |
Filecoin uses two types of proofs to ensure miners are actually storing data.
PoRep (Proof of Replication): generated when a miner first receives a file, proving the miner has stored a unique copy of the data (not just referencing someone else's copy).
PoSt (Proof of Spacetime): generated by the miner every 24-48 hours, proving the miner is continuously storing the data. If a PoSt fails, the miner's staked FIL gets slashed.
Together, these two proofs let the Filecoin network confirm data is genuinely being stored, with no room for miners to cheat. But generating these proofs requires heavy computation (miner nodes need professional-grade GPUs), which is why Filecoin mining hardware costs are high.
Filecoin is currently the largest decentralized storage network by data scale.
| Date | Data Stored on the Filecoin Network |
|---|---|
| Apr 2021 | 5 EB |
| Apr 2022 | 18 EB |
| Apr 2023 | 22 EB |
| Apr 2024 | 18 EB (some miners exited) |
| Apr 2025 | 16 EB |
| Apr 2026 | 18 EB |
18 EB (exabytes) equals 18,000 PB (petabytes), over 70,000 times larger than the Arweave network's 250 TB. But a large chunk of Filecoin's data is "self-filled" by miners — miners generate their own random data to store purely to earn FIL rewards, not to meet real customer demand.
Stripping out this "junk storage," Filecoin's real customer storage is estimated at 1-3 EB, still far larger than Arweave's actual customer data.
Filecoin fits several types of use cases.
Use case one: large-scale research data archiving. Institutions like MIT and UC Berkeley use Filecoin to store research datasets (such as genomic data and climate models).
Use case two: internet archiving. Organizations like the Internet Archive and Web Archive use Filecoin to back up historical web pages and media files.
Use case three: NFT metadata. Services like NFT.Storage and Pinata store NFT metadata on Filecoin (while also supporting IPFS and Arweave).
Use case four: Web3 social media. Some content from Audius and Lens Protocol is stored on Filecoin.
Use case five: enterprise backup. Some businesses use Filecoin as a decentralized alternative to AWS S3, mainly price-sensitive mid-to-long-tail customers.
Filecoin deployed FVM in 2023 — an EVM-compatible virtual machine that brings smart contract support to the Filecoin network. FVM extends Filecoin from a pure storage network into a "storage plus compute" platform.
| FVM Dimension | Detail |
|---|---|
| EVM compatible | Yes |
| Main application | Storage-related DeFi (such as SP lending) |
| Current TVL | About $100 million |
| User count | Small (a few thousand) |
FVM's biggest use case is "storage finance" — for example, miners can borrow other assets against staked FIL, or tokenize a storage contract's future revenue. This kind of "storage finance" has no direct counterpart in traditional finance, making it one of Filecoin's genuinely unique innovations.
| Dimension | FIL Token |
|---|---|
| Total supply | 2 billion (hard cap) |
| Mined so far | About 650 million (32%) |
| Current circulating supply | About 550 million |
| Inflation rate | About 5-7% (declining each year) |
| Halving cycle | 6 years |
| Last halving | Oct 2026 |
FIL's halving mechanism (halving every 6 years) makes its long-term supply predictable. But its current inflation rate (5-7%) still represents meaningful dilution for long-term holders.
Miner revenue breaks down into: block rewards (FIL inflation), customer storage payments (settled in FIL), and retrieval fees (data download charges). Currently, about 70% of miner revenue comes from block rewards and 30% from customer payments, reflecting that customer-driven real demand is still relatively small.
| Dimension | Filecoin | Arweave |
|---|---|---|
| Storage model | Recurring payment (180-day minimum terms) | One-time payment, permanent |
| Monthly cost per GB | $0.01-0.05 | $4-6 one-time (roughly equivalent to 200 years) |
| Data scale | 18 EB | 250 TB |
| Customer type | Large-scale, renewable | Permanent, non-deletable |
| Miner hardware | High (PoRep + PoSt computation) | Moderate (SPoRA storage) |
| Token economics | 2 billion hard cap, 6-year halving | 66 million hard cap, 200-year linear issuance |
| Current market cap | $3.5 billion | $1.2 billion |
| AI data storage | Partially supported | Strong use case |
If a user needs to store 1 TB of AI training data for 5 years: Filecoin's total cost is roughly $600-3,000 (billed per period), while Arweave's total cost is roughly $4,000-6,000 (a one-time permanent payment). From a short-term cost perspective, Filecoin is cheaper; from a long-term value perspective, Arweave's "permanent" guarantee carries a premium.
Between 2024 and 2025, Filecoin launched its "Filecoin for AI" strategy, focused on supporting AI training data storage and retrieval. Specific initiatives include:
FilCDN: a decentralized CDN on Filecoin that lets AI models retrieve training data quickly, rather than having to do a full download every time.
InferenceLabs: a partnership with AI projects like Bittensor and Ritual, letting AI models perform inference directly on data stored on Filecoin.
FIL Squared: FIL holders lend FIL to AI startups, which use it to store training data on Filecoin, forming a closed loop of "token plus compute plus data."
But real-world adoption of these initiatives is still in an early stage. Filecoin's standing in the AI-token sector isn't comparable to Bittensor or Worldcoin — it reads more like "storage infrastructure with an AI label attached."
Controversy one: miner self-filled data. In its early days, a large share of the data stored by Filecoin miners was "meaningless random data," stored purely to earn FIL rewards. This inflates how much of Filecoin's "18 EB" figure is real.
Controversy two: compliance and regulatory risk. Filecoin drew SEC attention in 2024, with some early investors facing securities-law inquiries. Protocol Labs maintains that FIL is a "utility token" rather than a security, but the controversy persists.
Controversy three: miner centralization. Filecoin's high hardware requirements (professional servers, GPUs, and large-capacity SSDs) mean miners are actually concentrated among a handful of large mining pools in China and North America. The top 10 miners control roughly 50% of the network's storage power.
Upside variables: an explosion in AI training data demand driving genuine Filecoin storage demand, "storage finance" applications on FVM taking off, and Filecoin successfully forming a complementary relationship with centralized cloud providers (AWS, Azure).
Downside variables: continued miner centralization, tightening regulation, and other storage solutions (Walrus, Storj) taking market share.
Neutral variables: the FIL halving (October 2026) is already partially priced in.
FIL has long underperformed most major cryptocurrencies. It has fallen from a 2021 peak of $200 to its current $5, a 97.5% drawdown. Its current $3.5 billion market cap still trades at a steep discount to its historical peak, but looks rich relative to actual customer-driven revenue.
Q: Can data stored on Filecoin be downloaded?
Yes, but download speeds can be slow. Filecoin is primarily designed for storage, and download (retrieval) speed is limited by miners' network bandwidth. Retrieval-acceleration services like FilCDN are working to improve this.
Q: How do I actually use Filecoin to store data?
The easiest path for ordinary users is a hosted service like Web3.Storage or NFT.Storage. These services abstract away the technical details of miner contracts and PoSt proofs, letting users upload files as easily as using Dropbox.
Q: How much does it cost to store 1 GB for a year?
Roughly $0.10-0.50 (fluctuating with the FIL price). That's significantly cheaper than AWS S3 (about $0.30/GB/month), but download speed and retrieval experience aren't as good as centralized cloud storage.
Q: Is FIL worth holding long term?
Short term, FIL tends to move with sentiment in the AI sector, and the 2026 halving could drive a rally. Long term, it requires believing Filecoin can build a moat in the large-scale storage market. FIL has historically underperformed BTC and ETH, so long-term holders should proceed cautiously.
Q: Which is better — Filecoin or Walrus?
They serve different purposes. Walrus is a decentralized storage network on Sui focused on "low-cost blob storage." Filecoin focuses on "large-scale, reliable storage." The two address different needs. Walrus is a newer 2025 project with an ecosystem far smaller than Filecoin's.
Q: Does anyone actually use the DeFi apps on FVM?
Yes, but at a small scale. FVM's TVL is around $100 million, mostly SP (storage provider) lending protocols. Ordinary DeFi users generally don't touch FVM.
Q: Can data on Filecoin be lost?
Theoretically no, within the contract term. Filecoin's PoSt mechanism ensures miners keep storing data continuously. In practice, though, miner outages or network issues can reduce the accessibility of some data. Important data should be stored with multiple copies across different miners.
Q: Is Filecoin mining still profitable?
Mining was highly profitable in 2021-2022 (high FIL prices plus generous block rewards). From 2023 to 2026, falling FIL prices combined with rising hardware and electricity costs have left most miners breaking even or losing money. New miners entering now aren't advised to participate.
FIL has fallen from $200 to $5 historically, a 97.5% drawdown, and has long underperformed mainstream cryptocurrencies.
