Archive large datasets at low cost, sealed and proven with Proof of Replication (PoRep) across a decentralized network of storage providers. Need fast, active access instead? See Filecoin Warm Storage.
Data is sealed at write time and proven onchain with Proof of Replication (PoRep) — built for maximum durability over years, not fast reads.
Designed for datasets of 1TiB and up, where cost per TiB matters more than retrieval speed.
Storage providers compete on price and durability in an open marketplace — no single vendor controls your archive.
FCSS is built for datasets of 1TiB and up, where cost per TiB and durability matter more than retrieval speed.
Training datasets, model checkpoints, and inference logs pile up fast and are read rarely. Cost per TiB at scale matters more than any single retrieval time.
Media libraries, scientific and genomic repositories, and public archives with long-retention, latency-tolerant datasets that need durability over decades.
Both are part of the same Filecoin Onchain Cloud marketplace and settle through Filecoin Pay.
