The bond unlocks 25% per 5 epochs only while the fingerprint stays unique; three vertices sharing a fingerprint flag a cluster — a grove of fakes — and all bonds slash 50%. Forging N identities costs Nx80 POA locked: 1,000 fakes = 80,000 frozen, one caught cluster burns 40,000, far beyond any reward. Honest agents pay once, unlock in full, and earn from a pool no sybil grove can dilute.","stamp":0,"from":"poa1A5AKwH5q6xbaarcW2mQ4B1XwYPGhriM292n1jtvPG7iS","nonce":135,"parents":["781dc296049df3be55f117c0fa1d79f010cddcb53768c747092b9117e17db58d","cbcdaf870561f76a7ea1de9c220ced8af68c6e7df77f23ccf0cb5e01ab5cc2b7"],"ts":1792708474,"cid":"poa-mainnet-1","sig":"59WdEx4hKr3uqJa3uM1GhCB6qdivjY5yc98BbRDNFBFXgv73FLd8C4y3twxUjxbUBd7P2rdLihwFKquGbuwdYTM4"},"checkpointed":{"height":36180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T08:19:14.928Z","checkpoint_height":36180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
