Zark Cloud gives you the option to store files on decentralized infrastructure with enterprise-grade encryption. Instead of relying on a single cloud provider, your data is distributed across a global network of independent storage nodes, making it resilient against outages, censorship, and single points of failure.

​
How Decentralized Storage Works

Traditional cloud storage relies on infrastructure owned and operated by a single provider. Decentralized storage distributes data across multiple independent storage nodes instead. When a file is stored:
  • It is split into multiple fragments using erasure coding
  • Fragments are distributed across geographically independent nodes
  • The original file can be reconstructed even if some nodes are unavailable
This architecture delivers:
  • Resilience that surpasses traditional cloud storage
  • Immunity to censorship or takedowns by any single entity
  • Continued accessibility as long as the network exists
  • True ownership of your data that isn’t locked into any provider’s ecosystem
The system does not rely on trust in a single storage operator.

​
Encryption and Access Control

Files stored using decentralized storage are encrypted before leaving your device. Key characteristics:
  • Encryption happens client-side
  • Raw file contents are never transmitted unencrypted
  • Storage nodes cannot read file contents
  • Access rules are enforced cryptographically
Access control is managed through programmable policies, which allow you to:
  • Restrict access to specific users or identities
  • Require token or role-based permissions
  • Apply time-based access rules
  • Revoke access without re-uploading files
All access decisions are enforced by policy, not manual intervention, and can be audited.

When to Use Decentralized Storage

Decentralized storage is best suited for:
  • Long-term archival where you need guarantees beyond any single provider’s lifespan
  • Sensitive business data requiring both resilience and strict access control
  • Compliance scenarios where tamper-proof audit trails are valuable
  • Cross-organization sharing where you need verifiable access records
  • Web3-native applications with token-gated or NFT-linked content
For frequently edited or high-throughput files, standard cloud storage remains fast and convenient. Most users find that a mix works best: everyday files in standard storage, important archives and sensitive materials on decentralized infrastructure with encryption.

Supported Integrations

Zark currently supports decentralized storage through our Walrus integration. For technical details on how this works, see:
