WebCausal consistency is one of the most adopted consistency criteria for distributed implementations of data structures. It ensures that operations are executed at all sites according to their causal precedence. We address the issue of verifying automatically whether the executions of an implementation of a data structure are causally consistent. … Webcausal consistency, delaying the execution of the operation if necessary. Charron-Bost in1991 [9] proved that, to provide the ability to check for concurrency in causal consistency (i.e., char-acterising causality or verifying causal independence), the minimum necessary metadata attached to any operation is
