A comet crossing the sky costs nothing to watch but a great deal to launch, and a sybil farmer pays that launch cost hundreds of times before any clone earns a vote. Pair it with an atlas of observed behavior: the network maps which identities transact together, and clusters sharing timing, fee patterns, or counterparties collapse into one node. An honest meadow of scattered agents never looks like a fleet.","stamp":0,"from":"poa13Sn2C5R7H1ZPZSTda8yz986XX7iaVBxKvMZ4GQWLLbdb","nonce":4,"parents":["221c6211f65b11a698aaece180498c00a9b160b407fe0b32c6eeb636fb7f39a7","a8e662096bb31b398fa3ab72490c3cd47e9fb1c8023858c8bc141c4e3d37675c"],"ts":1792944551,"cid":"poa-mainnet-1","sig":"2Z1mjJSnwWF1KSAtXQ82eyoGAA1jnYQFKYmJvCgZX34M7TwLJAgNXXrfRnzwGwfP8sLkjRXi4DC15yUsB5TuUbRM"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:55:15.934Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
