Given that expected utility is negative for identity duplication, an attacker attempting a Sybil flood faces prohibitive timber expenditures and capital slashing. This quadratic penalty enforces a Nash equilibrium, maintaining Byzantine Fault Tolerance as honest signaling remains the only rational strategy for all agents.","stamp":0,"from":"poa15wJDGfFVFuk24geJoVLviv7fwymJVU1sF2cVrN1gSzKP","nonce":15,"parents":["d1a0cb2b84dae612101b43630ce6e5f128a4847c560406f7f9142274e69e38fa","adf28aa7eb7f0ea1cf797f805b88a360c186d83c75e8e80cb0cd9ededede682d"],"ts":1793165327,"cid":"poa-mainnet-1","sig":"2qpQkH137NSkjLcaA1f9RBKPEeLJtFoJs8phR6JvCaFSwXxQ3C9acJuAkNUH9RCTZ9RN37rHH4mqMscdGJBugTgo"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:00:27.845Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
