• Filecoin archives Solana’s full chain on decentralized storage, ending dependence on traditional services for historical data.
  • PDP tech and Fast Finality give developers low-latency CID retrieval, while on-chain AI agents gain verifiable, tamper-proof data sources.

Filecoin’s role in the Solana ecosystem now goes beyond simple storage. The decentralized storage platform is a critical component of Solana’s data infrastructure, providing a complete and persistent archive of the entire blockchain history.

Filecoin isn’t working alone, instead it’s partnering with teams like Triton One and DCENT to run a project called Old Faithful—part of a larger initiative known as Project Yellowstone. They want to archive the entire history of the Solana blockchain into a decentralized storage, without having to rely on traditional corporate big data services.

With a Content Identifier (CID)-based approach , data can be searched and accessed directly from multiple storage nodes without having to ask a central server. It’s like having a giant library with no main door—anyone can enter from anywhere.

Filecoin’s role in @solana 's infrastructure goes beyond storage. It creates a persistent, decentralized record of the entire chain, accessible to dapps, RPC providers, and researchers through CID-based systems that provides reliable retrieval, indexing, and long-term access.

Filecoin Powers Real-Time Apps, Verifiable AI, and Digital Archives

On the other hand, Solana isn’t the only one benefiting from Filecoin’s power. In mid-June, Filecoin also partnered with Theoriq to build fully verifiable AI agents directly on the blockchain. The models and decisions of these agents are stored publicly on the Filecoin network, so their results cannot be changed arbitrarily. For AI developers who want high transparency, a solution like this is certainly a sensible choice.

Furthermore, in May, Filecoin also introduced PDP technology —or Proof of Data Possession. This allows users to access stored data quickly, without having to wait long, but still in a decentralized system. Coupled with Fast Finality, Filecoin now supports the needs of low-latency applications.

This means that this platform is not only suitable for archiving, but can also be used together for applications that require speed and transparency at the same time. Imagine a digital wallet system or trading platform that remains responsive, but its data is stored on a secure distributed network.

Interestingly, Filecoin’s role in maintaining the sustainability of cultural data is also starting to be seen. Recently, the CNF reported that the Flickr Foundation had uploaded the 1,000 most viewed cultural photos to Filecoin. The goal is to keep these images publicly accessible for the long term, even if the original site disappears from the internet.

Filecoin, together with the IPFS protocol, allows these photos to be spread across many nodes. So if one place goes down, others will still be active.

Back to Solana , the data that goes into Filecoin is not only stored, but also archived with a method that makes it resilient. Its storage capacity is also not small. Filecoin can record 2 to 3 petabytes of data per day, much larger than Solana’s data volume. In fact, now access to Solana history can be done publicly without any hassle and without special permission.

Meanwhile, as of the writing time, FIL is trading at about $2.19, down 2.49% over the last 24 hours, causing its market cap to drop below the $1.50 billion mark.
