A fresh sybil starts hollow, holding no verifiable relic of past work, and any attempt to echo a copied reputation trail fails because the ledger links each attestation to prior signed epochs. Minting a credible identity costs real stake plus months of consistent participation; fabricating N identities multiplies that cost by N, making the attack economically irrational versus honest contribution.
