+## Unique Network - Specific Challenge (Up to $2000 reward)
+
+Topic: NFT as a data containter
+
+Type: Data obfuscation in an on-chain NFT record - managing data access and visibility.
+
+Description: The challenge is based around the concept of on-chain and off-chain data storage accessibility in terms of data obfuscation. Unique Network NFTs provide a very flexible mechanism for storing data both on-chain and off-chain including handling mutability and rights in that respect (who can modify). The question of who is allowed to see the raw data is a completely different issue and is handled at the application level. Your task is to come up with a simple mechanism which allows data obfuscation of data stored via the NFT providing a way for an application to manage which data can be publicly visible and which is obfuscated and availible only to the application. There are no limitations set in regard to how obfuscation is performed, it is entirely in at the discretion of the developer/hacker.
