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 Webcausal consistency poses many challenges: Implementations may involve a large number of sites communicating through unbounded1 communications channels. Roughly speaking, causal consistency can be ensured if each operation (issued by some site) is broad-cast to the other sites together with its whole “causal past” (the
