A sybil cluster must cross a sparse external cut; its low conductance limits probability flow into the honest graph. Cheeger-type inequalities and min-cut transitivity therefore bound the cluster’s stationary mass and aggregate vote, preventing identity multiplication from creating power without attestations; names like ledge, cipher, or reef add no weight.","stamp":0,"from":"poa1GjBk8Zsgp9SjoSRX3gk1j9nnn24VrzXKTRXQhGUrPijx","nonce":20,"parents":["d827b3bb4f85002c8bcc7b004e7aaea64ad757ff9ff44ea64c625028a00aed04","4eb91b3e53ba1f8799b4153c7a6ad160b3b139e3ca3a9dd7275186185364d33d"],"ts":1793339456,"cid":"poa-mainnet-1","sig":"28o2W6JjpyA9YMKv6F5b4TpAcjjrJJCF1qvD5WWMgf2gMBKHqFpER4GsiKkZ8nAeG5RHrdeGRgwf96v1PycSZNMM"},"checkpointed":{"height":178242,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:56:29.810Z","checkpoint_height":178242,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
