- Filecoin started fast finality (F3) and used GossipBft to cut block check times from hours to just a few minutes.
- F3 increases Filecoin’s support for low-latency apps, and partnerships expand its role in AI and decentralized data integrity.
FileCoin finally enabled Fast Finality (F3) on the mainnet on April 30, 2025. This step is a new milestone in the history of distributed storage networks. Previously, Filecoin transactions took about 7 hours to be completely final. But now? It only takes a few minutes. The confirmation used to take 900 epochs is currently only taking 5-10 epochs. Crazy, isn’t it?
If you’ve ever felt frustrated because you had to wait a long time for the transaction to be fully effective, now is the time to sigh of relief. F3 is a kind of collaboration between high-speed information dissemination protocols and jamming resistance mechanisms as a solution with a new consensus system called GossipBft.
Nothing has been changed as it runs alongside the traditional consensus system of Philicoin, the expected consensus. Turbo function has been added.
Fast Finality (F3) will be live on Filecoin Mainnet!

catch up and target low-latency applications
Transaction speed is not just about user convenience. In the crypto space, verification time can become life-like. Applications such as real-time payments, interactive smart contracts, and on-chain gaming all require fast, reliable systems. Without it, it would be difficult to grow.
Filecoin seems to know this very well. This fast final upgrade has actually been prepared from April 14, 2025 through the release of the latest network version called “Teep.” The update simplifies sector-specific costs and incorporates support for temporary storage. So F3 is not a sudden project. Everything is pre-designed.
Furthermore, the existence of F3 also encourages integration with other blockchains. Cross-chain transactions can be performed more efficiently, as they reduce the risk of spending twice as latency for shorter finalizations. If you’ve ever wondered “Is File Coin only data storage?” now you should think again.
Meanwhile, investors are also increasing. CNF reported that inflows of funds into Filecoin for the fourth quarter of 2024 increased 21% to $99 million per quarter. This means that not only are users more and more confident, but there are also financial institutions and parties interested in FIL-based loans.
In the AI era, Filecoin has an additional role
It turns out that it’s not just fast transactions. On April 28th, Filecoin Foundation co-founder Clara Tsao spoke on stage at the AI Summit, a side event of Consensus 2025.
She said Filecoin helps ensure data is reliable. Especially when it is becoming increasingly difficult to distinguish between AI-generated content and human content. With blockchain, Filecoin becomes a “filter” of information, allowing you to distinguish between the actual one and the results of algorithm integration.
And this isn’t just a story. In its quarterly report dated April 25, 2025, Filecoin Foundation states that AI projects such as Recall, Theoriq and Ungate AI are already using Filecoin storage. They want the data they process to be truly reliable, and blockchain is considered the right answer.
In fact, Filecoin is actively working with rebellious and internet archives in the scene of cultural archive preservation.
Meanwhile, at the time of reporting, FIL is $2.72below 2.69% It will move sideways over the past 24 hours and over the past 7 days.
