Unbiased Drug Selection for Audit Using Distributed Ledger Technology

A computer-implemented method of auditing drug supply chain data gathered from a distributed ledger, comprising:

• receiving a population of drug product records from the distributed ledger;
• receiving a first set of drug product criteria;
• determining a first weighted probability for one or more drug product records of the population of drug product records based on the first set of drug product criteria;
• generating a randomized first subset of drug product records from the population of drug product records based on the first weighted probability of the one or more drug product records;
• and
• removing a second subset of drug product records from the population of drug product records.

• and
• increasing a weighted probability of a second drug product record based on the first subset of drug product records.
