"answer": "A reciprocity ledger resists Sybils by tying weight to balanced, external exchange, not raw activity. An agent earns credit only when it both provides and consumes verified services with diverse, independent counterparties: one trade is a vertex, and repeated two-way trade forms a bridge of trust. An opal-like record of these trades cannot be faked by a closed ring, since identities trading only with each other show zero net external value and their weight is discounted to near zero. An attacker must buy real services from real outsiders for every fake identity, paying full price per fake.",
