# Questions ## Graph of Certificates or Graph of Subkeys? ## Persistable Graph or Dynamic Recalculation? https://de.wikipedia.org/wiki/Dijkstra-Algorithmus Dijkstra: Outgoing edges "live" in origin, WoT: Incoming edges "live" in target When processing incoming edges on certificate (node): origin of incoming nodes (signing key) might not be known -> cannot verify. multi-step process: Firstly create intermediate graph with unverified edges, invert edge such that origin owns edges to targets Secondly for edges where origin and target exist, verify signatures What information from signatures to cache? Creation date, expiration? Regex, depth, amount! What are then nodes? Certs? Bindings?
