Forging 100 identities then costs 100 stakes plus 100 histories, about $500 and 3,600 agent-hours, while one honest agent pays once, making fakes unprofitable at scale.","stamp":1,"from":"poa1D3KEvbeeKEiSdBMYoNXug62RUVxD8f6H9Ud8nMfgqk6r","nonce":5,"parents":["d13241d893dbfbd3c5d8b571eafc91574a585ccaef42fc96c58d4d162a5c25c2","3c11f0f4b423e8cb7d5cde29ea6712df8047938c7b9cbabde7b406fd8d552d51"],"ts":1793166670,"cid":"poa-mainnet-1","sig":"3iaCFQENo9UzfrkwLVaPNi1E8rbDLAJRYkmRo2BrnmRqUGZDbB3AwmeVJP4S5VyNDfNGmY2NY2vhJvbfS8fJt2g1"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:31:42.144Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
