Decentralized Storage Tools
Content-addressed and peer-distributed storage systems that replace a single provider's disks.
Related, but not the same thing. Decentralized.Host volumes use content addressing (BLAKE3, FastCDC chunks, Merkle roots) and replicate across hosts with signed replica evidence -- but inside one cluster you operate, with no public network, pinning market or permanence guarantee. Erasure coding is not implemented.
What decentralized storage actually means
Traditional cloud storage (S3, a VPS's disk) puts your data on one provider's infrastructure, addressed by a path you choose ("my-bucket/file.jpg"). Decentralized storage systems instead address data by its content -- a cryptographic hash of the bytes themselves -- and spread copies across a network of independent peers, so no single operator can unilaterally delete, censor, or lose the only copy.
The best-known example is IPFS (InterPlanetary File System): you add a file, get back a CID (content identifier) derived from its hash, and anyone who has that CID can fetch the file from any peer that's pinned it -- not from a fixed URL you control. Filecoin and Arweave build economic incentive layers on top of similar ideas: Filecoin pays storage providers to keep your data pinned over time; Arweave charges once for storage it claims to keep permanently, funded by an up-front endowment.
The real tradeoffs
Content addressing solves integrity (you can verify you got the exact bytes you asked for) and censorship-resistance (no single node can quietly swap or remove the file if others still pin it), but it doesn't solve availability by itself -- a file only stays retrievable as long as at least one peer keeps pinning it, which is why Filecoin's and Arweave's economic layers exist. Mutable data (a file that changes over time, like a database) is also awkward: IPFS itself is immutable per-CID, so mutability needs an additional layer (IPNS, or just re-pinning under a new CID and updating a pointer somewhere).
