The MediLedger Project has built a blockchain ecosystem application that prevents counterfeit pharmaceuticals from entering the U.S. pharmaceuticals supply chain. From the lessons learned, we make four recommendations: 1) use a “benevolent dictator” and base governance on “consensus through collaboration”; 2) store the verification of transactions, not the transactions themselves, on the blockchain; 3) use zero-knowledge proofs to verify product and transaction authenticity while preserving full privacy; 4) use blockchain application capabilities not found in traditional technologies to fix ineffective IS landscapes.
