Decentralized Storage Explained

Traditional cloud storage keeps your data on centralized servers, making it vulnerable to outages, censorship, or breaches. In Bervice, we take a different approach: your files and passwords are encrypted locally and distributed across a decentralized storage network such as IPFS. This means no single entity, including Bervice, can unilaterally control or delete your content.

Each file is split into content-addressed chunks and given a unique CID (Content Identifier). This CID is derived from the encrypted file itself, meaning any tampering changes the hash and is immediately detectable. The blockchain can store these CIDs as integrity proofs without revealing the actual file contents.

Because decentralized storage is peer-to-peer, your encrypted files are retrieved from multiple nodes across the network. This improves availability: even if several nodes go offline, the remaining peers can still serve your content. Bervice maintains its own high-availability pinning infrastructure while also leveraging public gateways for redundancy.

Privacy in this model comes from end-to-end encryption. Before a file ever leaves your device, it is encrypted using post-quantum–ready algorithms. Storage nodes only see randomized encrypted blobs—without keys, they cannot interpret or reconstruct your sensitive information.

Decentralized storage also enables user portability. Since your files are stored on a public network (but encrypted), you can export and access them with any compatible IPFS node or service, even if you stop using Bervice. Your data remains yours, under your control, with no lock-in.
