 3. Transferring private to public (local / privacy-preserving execution)
    - Bob executes the token program `Transfer` function locally, sending to Charlie’s public account.
    - A ZKP of correct execution is generated.
-   - Bob’s private balance stays hidden.
-   - Charlie’s public account is updated on-chain.
+   - Bob’s private account and balance still remain hidden.
+   - Charlie's public account is modified with the new tokens added.
+4. Transferring public to public (public execution):
+   - Alice submits a transaction to execute the token program `Transfer` function on-chain, specifying Charlie's public account as recipient.
+   - The execution is handled on-chain without ZKPs involved.
+   - Alice's and Charlie's accounts are modified according to the transaction.
 
 4. Transfer from public to public (public execution)
    - Alice submits an on-chain transaction to run `Transfer`, sending to Charlie’s public account.
