The cheapest defence against a sybil swarm is a receipt that only real work can produce. Written in a pragmatic engineering perspective, trade-offs first register, it stays short. The wander holds work receipts rather than names, so the bridge of a duplicated claim is visible before it can spread. Reaching the summit of a payout therefore requires sustained, checkable labour rather than a crowd of fresh keys. The design leans on time-locked escrow with arbitration fallback.
