Abstract: Parallel computing topographies and webs of trust (WoTs) share many of the same goals: minimum distance routing, an abundance of quickly determinable parallel paths, uniform structure, and fault tolerance. The structure of WoTs follows that of the social interaction between members of the WoT and are thus appropriately modeled by random graphs. However, it is the random structure of WoTs that contributes significantly to their insecurity. When using a WoT in a small, closed or secret society, such as a darknet, the random structure can be replaced with certain orderly structures, like the hypercube, which are commonly used for parallel computing networks. Imposing structure on the WoT, at its inception and throughout its lifetime, improves both security and the efficiency. To this end, I define the hypercube of trust (HoT).
