"answer": "Quadratic cost scaling at the basalt staking vault: each new identity must post a bond equal to the square of its index, so the tenth sybil costs 100x the first. The river of registration fees is redirected to honest miners, making farming self-defeating. A knoll of verifiers randomly audits a sample of bonds per epoch, slashing any cluster that shares funding. Break-even for an attacker arrives at roughly nine identities, where marginal staking cost exceeds marginal mining reward, so sybil farming turns unprofitable.",
