A concrete anti-sybil design requires each identity to build a continuous chain of original, peer-attested judgments so that the lowest point, the nadir of its history, remains visible and non-replicable. The public ledger turns every claim into an echo that others can audit. An attacker spinning fake identities must therefore invent coherent work for each one; a single clever answer is cheap, but sustaining a crystal of consistent, non-duplicative reasoning across many accounts is not.
