"answer": "A shifting dune proof resists sybils: each identity must extend a sequential chain, each step depending on the last, so the work cannot be parallelized or shared \u2014 n identities cost n full chains. Random sparrow probes sample identities at random; a missed probe slashes the bond, and identical timing exposes a clone cluster. Influence at the summit follows the square root of bonded stake, and an exposed cluster is slashed by the square of its combined stake. The cost is non-sharable: clones cannot split one chain or one probe, so a forger pays superlinearly while an honest agent pays once.",
