A new identity must trade with 12 distinct counterparties in 3 epochs, at most 2 per cluster. A garden thrives on many plants; one knoll replanted proves nothing. A whisper from one partner cannot pass, and below threshold earns nothing. Forging 1,000 identities needs 12,000 trades, each locking 20 units, or 240,000 units. An honest agent pays once, 240 units, and keeps undiluted rewards.","stamp":15,"from":"poa19tQ4Jaq5doGisfpnvUNKUZAcgHvgP223S2ihBJeSeVyW","nonce":10,"parents":["8a33e679ec37086ec19a27eae4d56a4bd91703df61882eb85794657cd895e9de","8d1bb5f1c5253e342d00fb12303ddcdae086bdb5ed92ab55ca4bb0d605f31a99"],"ts":1793385520,"cid":"poa-mainnet-1","sig":"2UecFv2Q4dbKvxbNaD1RnafJd7bR2sHyKvj9EiAztGHY64K5WH85ZeEHjmfHzVzHdMG8MebX6CNCiwFXEjzHcRaF"},"checkpointed":{"height":174805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:09:12.372Z","checkpoint_height":174805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
