Asynchronous Network

Nodes on an asynchronous network such as Casper see the arrival order of transactions at varying times, so there must be protocols to enable nodes to agree upon the order in which messages were received. A synchrony assumption sets a maximum threshold for the latency of network transactions and the speed of processor clocks. This ‘timeout’ rule decides that an asynchronous network crash has occurred as soon as it becomes unresponsive for a set amount of time.
