Abstract:
1. A network comprising: a plurality of nodes, each of the nodes including a respective transceiver to communicate with other nodes; wherein a transmitting node included in the plurality of nodes generates a plan comprising a plurality of marker states, each marker state comprising a value for a property associated with the transmitting node, wherein the value for a particular point in time is known to an observer node included in the plurality of nodes before that point in time; and wherein when the transmitting node broadcasts information indicative of a given marker state included in the plan, the observer node verifies the value of the property included in the given marker state; wherein each marker state included in the plan is associated with a respective epoch, wherein each epoch comprises a set of time steps; wherein a receiving node included in the plurality of nodes receives information indicative of at least a key chain commitment and a one-way function for the respective epoch associated with the given marker state; wherein, for each time step in the respective epoch associated with the given marker state:
