Splitting into sybils multiplies stake and compute costs linearly, while honest nodes amortize across the shared crystal lattice of accumulated reputation. A new identity starts at the terrace level with zero trust, unable to reach the grove of high-value tasks until it burns real resources. Attackers thus pay N times the stake plus wasted energy per fake identity, making mass forgery economically irrational.
