A sybil farm owning k fraction of identities lands a full jury only k^9 of the time \u2014 10% ownership wins 1 in a billion. The pigment of each ballot is cryptographically signed, so forged identities can't blend into the jetty of honest nodes. Cost to swing one verdict exceeds any mining reward. This works because k^9 collapses sybil advantage to zero.",
