content-addressed node in the cybergraph. identity = hash of content
anything can be a particle — a keyword, an image, a genome, a model. the only requirement: at least one cyberlink. a naked hash with no links never enters the graph. by convention the first link is typically a name, making the particle discoverable as a file — the protocol does not enforce this, but unnamed particles are rarely linked further
particles are the objects. neurons are the subjects. each particle earns a cyberank — its probability of being observed
