Dual-IPFS Attribute Server — Architecture & Advantages

Public IPFS (Manifest CIDs)        Private IPFS Cluster (Encrypted + Pinned)
+---------------------------+     +-----------------------------------------+
| Public manifest CID (A)   |<--->| Encrypted attribute payload CID (B)     |
| - small JSON manifest     |     | - access-controlled (gateway/mTLS/OAuth)|
| - proof summary & metadata|     | - pinned for availability               |
+---------------------------+     +-----------------------------------------+

CodexIdentity uses a dual-IPFS design: publish lightweight attribute manifests (and proof summaries) to the public IPFS network for verifiability and immutability, while keeping encrypted attribute payloads inside a private IPFS cluster under operational control for availability and privacy.

  • Privacy: Sensitive payloads are encrypted and only stored in the private cluster; public manifests never contain raw personal data.
  • Availability: Pinning + managed private cluster guarantees low-latency reads for verification flows.
  • Verifiability: Public CIDs provide immutable references so third-parties can validate proofs without accessing sensitive data.
  • Auditability & Compliance: Immutable manifests create tamper-evident trails suitable for audits while encryption preserves user privacy.

How it works (high-level)

  1. Attribute owner encrypts the attribute payload and uploads it to the private IPFS cluster, which returns a CID (private CID).
  2. An attribute manifest (small JSON with metadata, proof summary, and the private CID reference) is published to public IPFS as a separate CID (manifest CID).
  3. Verifiers fetch the public manifest CID to validate cryptographic proofs; when authorized, they request the private CID through a secure gateway to retrieve the encrypted payload.
  4. The client (or user agent) decrypts locally using user's keys to generate/verify zero-knowledge proofs without exposing raw data to the verifier.

Tradeoffs & Operational Notes

  • Engineering Complexity: Requires private cluster management, gatekeeping, and synchronization between public manifests and private pins.
  • Cost: Pinning and private cluster resources incur operational costs compared to pure public IPFS usage.
  • Key Management: Secure user key handling is essential; lost keys mean irreversible loss of access to encrypted payloads.
  • Staleness: Ensure manifest updates and CID rotations are handled via versioning strategies in manifests.
