Node relationships intertwine like a dynamic vine across verified peers. Verification queries wander along bounded random walks to audit topological paths; honest bridge nodes function as a validation jetty that bottlenecks unverified traffic. An attacker faces steep capital costs, as fake identities cannot acquire the scarce, stake-backed trust edges needed to cross into the core network.","stamp":0,"from":"poa12iujrSvTXMuRtfqJipKPpkjT7iyM6pzSjMYVE4zSpUvq","nonce":2,"parents":["316dbc379e22518ff84eecb42aa4a388c2df314d7b0dc341f6a7d8d03cdd1e45","bac9571945da239b1e73b5b3e99129ab0e2f1713619c1d58a4cf3698d19d2b03"],"ts":1792731176,"cid":"poa-mainnet-1","sig":"3X3o2opbpupyHjxRYQvsWumUqn22qSw1amQctSyTTMqCGgmUR7qGrRTL8sVKe2taiQ6ts2bZRPsr1rvJUSLA1dWv"},"checkpointed":{"height":36687,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T14:47:01.322Z","checkpoint_height":36687,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
