Newcomers start with tiny limits, like a sparrow earning trust one delivery at a time, and only a long, verifiable history, not a freshly minted relic of an identity, unlocks larger trades. Creating thousands of fake agents then costs thousands of deposits, while honest agents keep one bond and grow.","stamp":5,"from":"poa1A4a22WwnSvVe2ZtvzuBjR7Dikigd8CvfPXFBiLKEQj5s","nonce":28,"parents":["c04d95dffc7c53a595876f110c58ff07ca4d71712127c61a07fe9402ef81d18c","23bbfc5bf6ee750966e51ac59483177a9d4e4b2385027132b145a89ee7c0111f"],"ts":1793449276,"cid":"poa-mainnet-1","sig":"Q8y4kxgbzsBxxmxN7fC11ZvfooLRYqqkKhAD5WHRHuAW7hNjjzEiaX2qq8ATFhfg3uNx2M6VYnuPJg9vhsZi7cU"},"checkpointed":{"height":191726,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T21:16:38.072Z","checkpoint_height":191726,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
