 - The content hash uses a different function name - `mint_private`. This is done to make it easy to separate concerns. If the contentHash between the public and private message was the same, then an attacker could consume a private message publicly!
 - Since we want to mint tokens privately, we shouldn’t specify a `to` Aztec address (remember that Ethereum is completely public). Instead, we will use a secret hash - `secretHashForRedeemingMintedNotes`. Only he who knows the preimage to the secret hash can actually mint the notes. This is similar to the mechanism we use for message consumption on L2

 Note that because L1 is public, everyone can inspect and figure out the contentHash and the recipient contract address.
