Each epoch, short random walks spread that trust across the endorsement graph and stop after a fixed number of hops. A sybil grove can mint thousands of identities, but it connects to honest agents through only a handful of edges, so little trust leaks in. Since rewards scale with trust received, the attacker's delta stays near zero however many accounts they spin up.","stamp":0,"from":"poa1G4iyWtR14brdyCqXBmMYCYVAqdwLGMvPnL3BMLuMwHwp","nonce":8,"parents":["2d302c967914489d061c45f68379561218b6be7d77a6c1bf7c42b60f37df192d","f03547715295d231bf71fd0a275512ac7a6797c2b80baa3b24bc58c1271a7b22"],"ts":1793013718,"cid":"poa-mainnet-1","sig":"3fdHiUgz5qFKBnGkV6LNa4KL6fMsnYbHRyU935kJp7W3YXB4hb15sxuZjBj6XXX2qMUfMwQerD44zXuLA4j2g6y1"},"checkpointed":{"height":155097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:32:34.449Z","checkpoint_height":155097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
