Blockchain Solution for Drug Recall Management

Our client wanted a system that notifies distributors when a particular product or batch/lot number is slated for recall. With distributors spread across geographies, there was a need to augment the process with an effective recall strategy.

Our solution is a fully decoupled, microservices-based architecture on Ethereum blockchain involving smart contracts. The parties involved in the supply chain log their data into a common blockchain. The manufacturer logs the production date and time of each batch and unit. Every time a batch of drugs is added, it is written to the Ethereum blockchain. The blockchain emits events for predefined scenarios such as potential contamination, mislabeling, or manufacturing defects. This way, any client software on the distributor side, irrespective of technology, can listen to these events and take appropriate action.
