Programmable Access Control
Access rights can be managed using smart contracts on Sui
Developers can define:
Who can read data
Time-based access
NFT / token-gated privacy
Example:
Only NFT holders can access a private video stored on Walrus.
5️⃣ On-Chain vs Off-Chain Privacy
On-chain: Metadata, permissions, ownership (transparent).
Off-chain (Walrus): Actual file content (encrypted & private)
This hybrid model balances privacy + verifiability.
