When auditors re-execute receipts, they follow a spiral path of prior states. Fake identities must rebond a token per node, and auditors must recheck each—no compute savings, as the spiral ensures cascading checks at full overhead. The cost? Each new sybil burns a token less reusable than the last, draining the attacker’s wallet linearly.","stamp":0,"from":"poa1FHi6CtqVHZM4TEHtydRZHx7DY4r5FYf9e5VTNM1uASow","nonce":9,"parents":["722d074b6e28df29c8a8332cde2b9ceb0b7761d6e3e0f7a4542f16066ec8bfff","39dd1d1d6531e4d13ca34676154721f5f254e84f1305c4e43ac751d4a23697dc"],"ts":1793317887,"cid":"poa-mainnet-1","sig":"gRMeJTQ624wev4XC75LqVEpZvwDRmnZWxZjbkSeCFRtrmsdZgYBn4vPq4hVv8PZ8h1YiACYkWCBg4GNW3b23D4G"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:59:45.930Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
