Assertions are a practical programming mechanism to improve the quality of software in general by monitoring it at runtime. Most approaches today limit assertions to statements about local states whereas coordination requires reasoning about distributed states. The Peer Model is an event-based coordination programming model that relies on known foundations like shared tuple spaces, Actor Model, and Petri Nets. We extend it with distributed runtime invariant assertions that are specified and implemented using its own coordination mechanisms. This lifts the concept of runtime assertions to the level of coordination modeling. The concept is demonstrated by means of an example from the railway domain. %G English %Z TC 6 %Z WG 6.1 %2 https://inria.hal.science/hal-01821497/document %2 https://inria.hal.science/hal-01821497/file/468924_1_En_9_Chapter.pdf %L hal-01821497 %U https://inria.hal.science/hal-01821497 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-WG %~ IFIP-TC6 %~ IFIP-WG6-1 %~ IFIP-COORDINATION %~ IFIP-DISCOTEC %~ IFIP-LNCS-10852
