Note

L'attacco di Sybil è un attacco informatico dove i sistemi di reputazione sono sovvertiti falsificando le identità di una persona in una rete p2p. In a Sybil attack, the attacker subverts reputation system of a peer-to-peer network by creating a large number of pseudonymous identities, using them to gain a disproportionately large influence. A reputation system's vulnerability to a Sybil depends on how cheaply identities can be generated, the degree to which the reputation system accepts inputs from entities that do not have a chain of trust linking them to a trusted entity.
