Described is a system for a verification microservice engine for generating and deploying a controller module and one or more worker nodes to detect corruption in a deduplicated object storage system accessible by one or more microservices while minimizing costly read operations on objects. A worker node(s) stores slice recipes into worker node memory that correspond to slice recipe names verified by a controller module. For each slice recipe, the worker node(s) detects whether slice recipe corruptions, similarity group corruptions and/or compression region corruptions exist.
