Overview
Filecoin is a decentralized storage network: a marketplace where people and companies pay to store files, and storage providers around the world earn FIL for keeping them. It was created by Protocol Labs, led by Juan Benet, the company behind IPFS, a popular system for sharing files across the internet.
Filecoin raised about $257 million in a 2017 token sale, one of the largest ever, and its main network launched in October 2020. It now has an enormous amount of storage capacity, measured in exabytes (billions of gigabytes).
How it works
- A customer makes a storage deal with one or more storage providers.
- Providers must lock up FIL as collateral and regularly submit cryptographic proofs that they are still storing the data correctly.
- If they fail, they lose part of their collateral.
Providers also earn block rewards in new FIL for contributing storage. Since 2023, the Filecoin Virtual Machine (FVM) lets developers build smart contracts that automate storage, payments and data workflows.
2026: from capacity to customers
For years, Filecoin grew its storage capacity mainly by paying providers with new FIL, while actual paid storage stayed small. Much of the stored data was free or subsidized.
The Filecoin community’s 2026 strategy shifts the focus to paying customers:
- Filecoin Onchain Cloud, unveiled in late 2025, packages decentralized storage into cloud-style services for apps and AI projects. Early users include Monad and AI data teams. Its paid volume is still very small.
- The Solstice upgrade, scheduled for October 2026, would direct a growing share of rewards (from 5% up to 50%) to providers who attract paying storage customers.
The FIL token
| FIL at a glance | |
|---|---|
| Maximum supply | about 2 billion FIL |
| In circulation (Oct 2026) | about 836 million |
| Price (21 Oct 2026) | about $1.03 |
| All-time high | about $237 (April 2021) |
| Market cap | about $860 million (#84) |
FIL pays for storage, serves as collateral for providers and rewards them for securing the network. Tokens for early investors, the team and Protocol Labs vested over six years and finished vesting in October 2026, which cuts new FIL entering the market by roughly three-quarters.
FIL’s all-time high came in the first weeks of trading in 2021, when very few tokens were in circulation; it has fallen about 99% since.
Security and reliability
Filecoin’s network and proof system have run without major hacks. The main risks are economic:
- Demand gap. The network has far more capacity than paying customers. Until paid demand grows, rewards rely on new FIL.
- Competition. Arweave offers permanent storage, Walrus (on Sui) targets apps, and Amazon, Google and Microsoft dominate cloud storage.
- Complexity. Storing data on Filecoin is harder than using a normal cloud service, although new tools aim to change that.
Filecoin vs. the competition
| Filecoin | Arweave | Walrus | |
|---|---|---|---|
| Model | Storage deals for a set period | Pay once, store “forever” | Storage for apps on Sui |
| Launched | 2020 | 2018 | 2025 |
| Scale | Largest capacity | Smaller | Growing |
| Smart contracts | FVM | Via AO | Sui |
Our verdict
Filecoin built the world’s largest decentralized storage network and is now doing what it should have done earlier: focusing on paying customers. With vesting over and new supply falling, the token’s supply side is improving.
But demand is still tiny, and FIL has lost almost all of its value since 2021. FIL is a high-risk bet that decentralized storage, especially for AI data, will finally find real paying users. Invest only what you can afford to lose.
