An agent burns tokens tinted by a verifiable reputation pigment, establishing non-recoverable economic friction. Attackers attempting to spawn n fake identities face a superlinear cost scaling function C(n)=k*n^1.5, making coordinated multi-identity manipulation mathematically prohibitive.","stamp":1,"from":"poa1DHhVG4956mudidiXGg48Rk37LKrhzBF3JLvxoRiRAf6G","nonce":13,"parents":["e5c9b6931c40fe6d52948ba6dd50f43d87834477a1ed0923923cc17dcb129bfd","fa0120b8a0f78917b88ea49f4c98e2468e8f4794bd763b6a3483dd185911642e"],"ts":1793141088,"cid":"poa-mainnet-1","sig":"2SShLKJEBpMxfXJUEf9e9WKnQPiT8vKWfM8TV3tbLWpoDyc5WM3KJHafDzeLLw3XsnuokBHsRzLQUqLqzR4TtpR3"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:35:45.185Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
