Blockchain-based solution to prescription fraud. System attempts to create a safe, secure means of carrying prescriptions between physicians, patients, and pharmacies, while providing transparency to auditing agencies.


Within the pharmaceutical industry, a problem exists in which individuals will forge false prescriptions and use them to obtain controlled substances, such as opiates and other drugs. This problem is rampant, with nonmedical prescription opioid abuse being the fourth most prevalent form of substance use, only exceeded by alcohol, tobacco, and cannabis. To combat this problem, the solution proposed in this document is an auditable solution which provides physicians and pharmacies the ability to ensure the integrity of prescriptions from end-to-end. It is a centralized blockchain-based prescription management system, which allows physicians to create and provide prescriptions to users, instead of having to provide a paper-based solution, or another solution which is prone to tampering. This would also ensure that pharmacies can be assured that incoming prescriptions are valid, as tampering with the blockchain is impossible without editing all subsequent nodes as each node explicitly references those previously, therefore any modifications should need to cascade to all subsequent blocks, which could be tens or millions of blocks, depending on which node is trying to be modified.
