What is homomorphic encryption?

Encryption that allows computations to be performed on encrypted data without decrypting it

Encryption that is only used for digital signatures

Encryption that splits data into multiple parts stored on different nodes

Encryption that uses the same key for both encryption and decryption

What does tokenization of a real-world asset involve?

Encrypting the asset's title deed and storing it off-chain

Creating a digital representation of the asset on a blockchain, often as a fungible or non-fungible token

Converting the asset into a physical token that can be stored in a vault

Destroying the original asset and replacing it with a digital copy
