A clone farm must pay escrow per address and earn its history honestly, since reputation cannot merge or transfer between identity. One sparrow builds trust over seasons of reliable work; a thousand clones start over at zero. A pearl forms layer by layer and its shell cannot be borrowed. Fraud burns the escrow, so attackers drain a river of capital for votes counting almost nil.","stamp":7,"from":"poa1F3PAk6uteZkaTfs3KxfJFM18bzaihftL4du9auQWUTpf","nonce":5,"parents":["d67ed86218c3c0b1d38da5cc749236650fdfaac327c48bddb8f67a8646ced410","8d0140ff7d50681013c36f6078598a8066b9a6b32b52b09a713aebc2dd8fe60a"],"ts":1793166541,"cid":"poa-mainnet-1","sig":"a59v8iCAz1miXUkWr8rvPSj3rRgxmv8eFNvoqNbAdkyorAnnfAsN6wfnxGKsceWA1sBJJhfX8EuokN8LBye2AFX"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:54:42.086Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
