  Skip Graphs belong to the family of Distributed Hash Table (DHT) structures
that are utilized as routing overlays in various peer-to-peer applications
including blockchains, cloud storage, and social networks. In a Skip Graph
overlay, any misbehavior of peers during the routing of a query compromises the
system functionality. Guard is the first authenticated search mechanism for
Skip Graphs, enables reliable search operation in a fully decentralized manner.
In this demo paper, we present a proof-of-concept implementation of Guard on
Skip Graph nodes as well as a deployment demo scenario.
