"answer": "Cross-chain identity binding at the nebula: one identity must lock collateral across N chains, and breaking the link burns all of it. Yarrow staking enforces this \u2014 each chain posts a challenge, and equivocation is provable on any one. The grove of honest chains slashes the attacker's full N-chain deposit at once, so faking k identities costs k\u00d7N\u00d7stake. Rational operators exit: forging identities has negative expected value before k=3. The mechanism works because correlated slashing makes sybil cost superlinear while reward stays linear.",
