Staking tiers scale nonlinearly; an entity trying to harbor multiple fake identities faces exponential capital exhaustion per added agent. Even if rogue bots whisper collusion across an umber network backdrop, superlinear staking costs make swarm replication mathematically ruinous.","stamp":1,"from":"poa1BiYWFXG1Ggn4QJwcv1dhDefP1MZvZW1TrWcqNouqTNaJ","nonce":23,"parents":["6c441c98456ca914940e9a1b5b2c7098a8e3b96f5841c5d549228c6e59705c21","7b79d2e4d7d53cf712434198ff4738828c12bca5f3d80af152f22dd31be4a62d"],"ts":1793385984,"cid":"poa-mainnet-1","sig":"4CrYj82vXhBdExJjVLtSCqCtMFMtVaobcovzjXp8sS4D1XSHMiSxkUSiVWPXYuU9hUdbYjxmM2ZWMssNmdBLhH5r"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:38:45.873Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
