Cardano and Filecoin are pushing their storage relationship further, with new remarks from Input Output CEO Charles Hoskinson and Filecoin Foundation President Marta Belcher outlining how the two ecosystems are already connected through Blockfrost and where they may go next. In an April 29 interview, the pair described Filecoin as an increasingly important storage and backup layer for Cardano applications, particularly as developers look for more resilient infrastructure for governance records, dApps, and emerging AI-related workloads.
Cardano Expands Filecoin Storage Ties
Hoskinson said Input Output has been building cross-chain relationships across the industry and noted that one of its subsidiaries, Blockfrost, had already completed “some very nice integrations with Filecoin.” He added that many Cardano developers may not realize those tools are already available. According to Belcher, the relationship is not just exploratory: Filecoin is already being used as a storage layer for Cardano applications, with an emphasis on redundancy, verifiability, and resilience.

Belcher, who leads the Filecoin Foundation, described Filecoin as “the world’s largest decentralized storage network” and said the network has grown to exabyte-scale capacity after more than five years on mainnet. “We’ve really built through multiple cycles and we’ve reached, I think similar to Cardano, a maturation phase where Filecoin has this production grade infrastructure operating at scale with a global network that is hard to replicate,” she said. “You can really see the maturity with the type of data we’re storing. So we have data from the Smithsonian, from MIT, from the Flickr Foundation, the Internet Archive, a lot of AI training data and governments around the world.”
Hoskinson used the interview to frame the scale involved, saying an exabyte is large enough that downloading it over a 1 gigabit-per-second connection would take roughly 250 years. He also tied the partnership to Cardano’s broader infrastructure needs. “Data corruption, availability, the audit log, this is just a match made in heaven,” he said. “And it’s the thing that we’ve always been missing from blockchains.” He added that Filecoin had also been used as one of the storage services supporting Midnight’s Glacier drop, which he said involved 33.6 million accounts and large amounts of off-chain metadata.
Blockfrost Integration Opens New Tools
Belcher said Blockfrost has integrated Filecoin “as this backup layer for Cardano applications,” allowing dApp developers to store data on Filecoin directly through Blockfrost. She said Blockfrost also archived its IPFS gateway clusters on Filecoin, creating a combined IPFS and Filecoin storage offering for Cardano builders. According to Belcher, the integration is live across all Blockfrost tiers and has already processed more than 170 Filecoin storage deals.
She said the practical effect is broader than simple storage. “Cardano dApp developers really gained this new way to store data on Filecoin directly through Blockfrost,” Belcher said. “This integration is live, it’s available across all Blockfrost tiers, and it has already had more than 170 Filecoin storage deals processed to date.” She added that the setup gives builders data redundancy, stronger provenance, and a more durable base for applications that need auditable records, including AI systems and governance archives.
Belcher also pointed to Cardano’s use of IPFS in governance, saying governance artifacts including the Cardano constitution can be referenced through IPFS hashes rather than mutable web links. That matters, she said, because “the governance archive isn’t just a bunch of documents, it’s actually a verifiable record of what was decided, when it was decided, what language was agreed to.” Looking ahead, the discussion also touched on newer Filecoin products including Filecoin Onchain Cloud and a recently introduced S3-compatible access layer called Fill1 or “SpillOne” in the transcript, which Belcher said is designed to make decentralized storage feel more like a familiar Web2 service for enterprises and developers. She also said Filecoin Pay is being developed with the goal of eventually letting users pay for storage “with their own native tokens,” though no rollout timeline was specified in the interview.
