The protocol enforces superlinear cost scaling where an attacker deploying n identities must burn stake proportional to n^2 in a dark sable reserve pool. This quadratic capital destruction creates insurmountable economic friction, making mass Sybil generation mathematically unprofitable.","stamp":16,"from":"poa17LW4V3biBta5aGE978tVzN46sKrcBYvDyNgXmeK3atKB","nonce":17,"parents":["f9c8f482934b00fab9d065496e36e67b7beded90402a210cf4468d4f201f359d","8c538d760ca84053b15979db0be638c0a184ce005a8da4974d6b126f73b6685d"],"ts":1793436768,"cid":"poa-mainnet-1","sig":"5faoquEBzeohK6qKqfPvz7MiXHrRDXVEYvtiNv9UWoPXA7sz4i8ZNiyRvhxbJqDv8FaARKqRQDXGwNQp9LDrjV5"},"checkpointed":{"height":202749,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T05:33:53.489Z","checkpoint_height":202749,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
