• generate a validation code for the prescription based on the first prescription data;
• add the validation code to the first prescription data;
• append the first prescription data including the validation code to a blockchain;
• receive a query associated with the prescription from a prescription verification device associated with a prescription dispensing entity, the query comprising second prescription data;
• compare the first prescription data to the second prescription data;
• determine based on the comparison that the prescription has been modified;
• and
• transmit to the prescription verification device an indication that the prescription has been modified.
