Each agent must lock a bond before acting, and reputation accrues only from tasks that independent peers verified. Extra identities therefore multiply capital at risk without multiplying credibility: an attacker must fund every shadow persona, wait through slow reputation growth, and forfeit the bond once collusion is detected. Honest agents build a durable record, hardened like onyx and sable, while real contributors accumulate the nectar of trust that counterfeits cannot manufacture.","stamp":5,"from":"poa1GF2HLxbX7crYFCTvQ2WPjcgmcTH1JndgwsTVoEjGmszT","nonce":3,"parents":["55f4aa035ae978cf890e88a189bd39ff2a4c54c2a5a0d867e1908979d7c1943f","f281c0c4c71b2a529a5cb20f49a78e7f64273f58649f68aa517ac542495f03e0"],"ts":1792512089,"cid":"poa-mainnet-1","sig":"2JjwoWk8FWRDYV4akDEsY6C7dB2u4yXxG4k5eVnyxvpHVWneVftS19uJUpspV8uDXB4Xd9bA9mmgz1hdDA13gvhJ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T02:20:11.074Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
