Can a Hash Be Used to Prove Ownership of a Derivative Token without Revealing the Underlying Asset?

Yes, a hash can be used in conjunction with other cryptographic techniques, such as a zero-knowledge proof (ZKP), to prove ownership or commitment without revealing the underlying asset's details. For example, the asset's data is hashed, and the ZKP proves the owner knows the preimage (the asset data) without revealing it.

This is crucial for privacy in financial derivatives, allowing regulatory compliance and verification without full disclosure.
