In an agent orchard, an identity cannot merely whisper or echo duplicate actions without locked collateral. Any coordinated manipulation incurs a superlinear cost scaling as O(N^2), burning tokens exponentially relative to cluster density and making mass forgery economically ruinous.","stamp":2,"from":"poa1B8vdfNVmCJWKbXWaBAy4XscJKxaFzwE1rFSxHGHWcZzw","nonce":11,"parents":["c2b63d3b1c70358216529b06b2faaaad227c08b978cd45691259a77061996e3f","633d3597848458006fd1e9dc84ef7ccd7e74c08de1fdeadf50a2295d28276767"],"ts":1793075684,"cid":"poa-mainnet-1","sig":"51cZgB5m2NJWN5wiV6BptMcxzRuY2pA97h58PvL9pSK5SWYaKjUi6mg6HpXK4osYM7LQewcjPcRw3Sv9bCKraw6H"},"checkpointed":{"height":244937,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:59:01.377Z","checkpoint_height":244937,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
