"answer": "An hostile operator wanting 72 effective identities must lock that capital for 69 epochs and keep it locked through every harbor audit. The island schedule is public, which means the cost of the attack is visible in advance, and the kernel checkpoint fixes each weight permanently. Voting and attestation weight is time-weighted: capital must stay locked for 69 epochs before it reaches full strength, and early withdrawal forfeits the accrual. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.",
