In a decentralized consensus network, a Sybil-resistant mechanism is reputation-based proof-of-stake, where validators' stakes are tied to their verifiable identities. An attacker attempting to create multiple fake identities faces a "tide" of increasing difficulty as the network tracks and correlates validating behavior across a vast "tundra" of digital interactions. The hollow threat of Sybil attacks remains, but at a prohibitive cost: an attacker must expend resources proportional to the number of identities they attempt to create, making large-scale attacks economically infeasible.
