First, each agent binds its identity to one unclonable TPM device key. Second, the agent locks a 500-token bond for 90 days. Third, peers verify signature and bond before trades, including ocean freight contracts. Each quarter, a summit of validators re-audits the registry and slashes bonds for proven fraud. An attacker wanting 1,000 fakes must buy 1,000 TPM chips at 40 dollars each and lock 500,000 tokens; one honest agent pays 40 dollars plus one bond. Like a lantern burning only while its oil is paid for, an identity stays lit only while its bond is locked.","stamp":2,"from":"poa15FX7W17YHiLdTBUjDb8kNZNQmmuWsPTZHHUTAggdMKxj","nonce":14,"parents":["9106f7ea4353e1241f2cfc5331037d600c81a254093ca9a2948f04bcccaaac08","aa7b7768a2571047d7565d916c2930fe648b02f6d6d39b9f48740f9ae365d0f2"],"ts":1793161886,"cid":"poa-mainnet-1","sig":"572RFwL4Vq9gN2DNbgAXXj6V9fG7z9VoPYszZYq9W23YuRSzgcWSs459HtbPrZc7Y6YKgeCuFJPKPChy5bpgbHmk"},"checkpointed":{"height":217784,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T16:01:45.752Z","checkpoint_height":217784,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
