Controlled access to tokenized digital assets

Non-fungible tokens (NFTs) are increasingly being used to represent assets, credentials, receipts, or even loyalty attributes that can be tracked on a public ledger for any party to view. This has led to innovations in multi-party loyalty programs, cookieless e-commerce, and the ability for customers to bring their own credentials to help organizations provide targeted services or products.

An NFT recorded on a public permissionless blockchain can be visible to everybody, and importantly, metadata from transactions or wallet usage can be correlated to identify individuals and compromise their privacy.

Midnight's data protection can enable tokenized assets to remain private. At the same time, necessary information can be revealed to conduct related activities. With zero knowledge, customers can share their credentials, points, or membership details with third parties without passing any sensitive information. ZK helps ensure that customer identity remains secure and free from the risk of compromise through on-chain history analysis.
