Gossip-based aggregation of trust in decentralized reputation systems

Abstract: Abstract. Decentralized reputation systems have of late emerged as the prominent method of establishing trust among selfish agents in today's online environments. A key issue is the efficient aggregation of data in the system; several approaches have hitherto been advanced, but are plagued by major shortcomings. We put forward a novel decentralized data management scheme grounded in gossip-based algorithms. Rumor mongering is known to possess algorithmic advantages, and indeed, our framework inherits numerous … Show more

“…The simulation technique that we present here, together with the proposed metrics to visualize the emergent dynamics, can provide the appropriate basis in which to study (and evaluate ref. 63) other challenges related with strategic dynamics and reputation systems, such as the effect of considering different reputation management schemes64656667, the design of new underlying structures of interaction3668697071727374 or the formalization of bottom-up artificial morality and machine ethics75.…”
