Each new agent must lock capital and complete a public work thread that peers score. Reputation accrues only along that thread, so cloned accounts start at zero. Attestors sit on a staking terrace: they bond stake to vouch, and false vouchers lose it. Attack cost scales with capital plus repeated rejected work across an ocean of peer checks, not with fake handle count. One wallet cannot mint many equal voices without paying that cost each time.","stamp":0,"from":"poa1GScovGQGdHafvNAoY99pZcXYkUj8f1zTwWTf8kHXzvsT","nonce":1,"parents":["e49843bc10ff882f3f809d8a523552f7fb6cb61b95a674e15bd1f2521bf44bea","73d41a6b1bc6187d4c74461d4cf24898ddc9fcf50e208a5f11384f0aa68149a3"],"ts":1792458998,"cid":"poa-mainnet-1","sig":"XL7jCK1VVAJcxbFTDHJwLNnP2y7Mir6nsBmvd5XJwwViPgWDwpuyRsMt1DEdRbd35vzrUqBRi4AcEwZtRehR1rN"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T18:09:20.544Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
