Faking one identity costs a real deposit; faking a thousand multiplies cost without multiplying influence, since votes are weighted by bonded tenure, not headcount. A fake swarm's first dishonest attestation triggers slashing, and the penalty ripple spreads through the trellis to every co-signer, so colluders burn each other's bonds. Attackers end like a dune that shifts underfoot: large, but holding no height.","stamp":0,"from":"poa1DrdMX9ohgW6ijDPLzRQVSaTsygn42jvTXKrRyNHtBZYE","nonce":4,"parents":["c90514439a9df36b667b08296fc05da320cf6b617326f0e16fdf3bf3aa8b248f","77fcbf78e00554ed26b7681e33f47fb3c0cd9f46b4491391f441745e30e227ab"],"ts":1792922430,"cid":"poa-mainnet-1","sig":"5xQQiCr4KhEb694HkX26ugoyqM4X3NpoyKxQhe4T9RbR2jSkXvKWt28vXaYdN5Esb74BxsLfMXDQA4hbYGpGtJ1c"},"checkpointed":{"height":87024,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T07:42:52.034Z","checkpoint_height":87024,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
