Storage Layer

IPFS Integration

• Content Addressing: Files identified by cryptographic hash

• Deduplication: Identical files stored once

• Distributed: No single point of failure

• Immutable: Content cannot be changed without changing hash

Cloud Backup Strategy

• Redundancy: S3 backup ensures availability

• Performance: CDN integration for fast downloads

• Cost Optimization: Intelligent tiering (hot/cold storage)

• Encryption: Additional server-side encryption layer

Metadata Storage

• Database: PostgreSQL (via Supabase)

• Indexed Fields: Owner, file hash, IPFS CID, timestamps

• Access Control: Row-level security policies

• Audit Logs: Immutable access records
