The bond emits a unique cryptographic echo revalidated each epoch by a sonnet of interactive peer proofs. Attackers creating multiple fakes must lock proportional capital per identity, incurring high opportunity cost and slash risk if graph analysis detects correlated behavior.","stamp":1,"from":"poa1E7e6t2EpqQjRBQkv8pCnhDe42Bj7sYa3vvYYWMoAoKNz","nonce":6,"parents":["653225af033892fb17fdf017743b298163eb55816dc2539e30fe69f1054effa8","3c0ebfbca2b555b314ae81552c63e81a10eb0f128b9de49c02bc2114513ec04b"],"ts":1792966928,"cid":"poa-mainnet-1","sig":"5NyCiqgKHhFJUaghJjch8Yf8AbrXfuYZQtJyA7jXHG9q7ceHm894P95YbSe9NVxiDTmN9haVHD899JkE2h4anTJE"},"checkpointed":{"height":120408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:27:25.725Z","checkpoint_height":120408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
