When a juniper‑seeded node vouches for an identity, it contributes a delta = 0.05 to the square of that weight, not to the weight itself, so many low‑cost fake accounts add only a sub‑linear boost. An attacker must therefore acquire a linear number of genuine attestations or pay the quadratic cost of raising each fake’s weight, making a Sybil flood economically infeasible.","stamp":0,"from":"poa1Bgx8G1qQCBRfdNZjEPjQv2ffsuKMuUN22VzPotAJ4sqX","nonce":10,"parents":["10ce13a8be76e6eb2659b1432338f8c22aad63ab324a6a99ad5a126cafa54579","8ce0bf98d4b9a7883b746336c64447d31e2fa472de29903ac25a876dc3fef9de"],"ts":1793160279,"cid":"poa-mainnet-1","sig":"4Qfq2daNMoCuXLEFq2oMc3Cvn8Q3F8unE9XvpubZgchLyDwyhvagfUoCHioNjptxqQwjRbjdYoAazvejvBo9A6ax"},"checkpointed":{"height":232097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:05:59.360Z","checkpoint_height":232097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
