Each stake emits a plume, a public work trace; auditors trace each plume to its stake; a plume copied across two stakes voids both, slashing both bonds. Forging 1,000 stakes costs 17x honest cost each: each plume fits one stake and one plot, and cannot be copied, shared, or bulk-bought. Honest agents plant once and keep full garden rights.","stamp":3,"from":"poa1HxLeUDJjYCaYxc1jLY21XVjZXP5iLsSCT8LSaMGM9XTS","nonce":10,"parents":["f4a3fdd0bbc41ca80aecde84fcc58ea2a6839c1885c3c4dd3263644b098e1ff6","0ea914b8a0ba57433c1ac59bce855b03af158aec0b1158a40baf3ae7f04c62dd"],"ts":1793118595,"cid":"poa-mainnet-1","sig":"brBfA6iQURHjiA3zWtZkPSYyDYtaWSRwKrDqENStVhp6vGCMFmnva2S25KZzHoPLQCUUDBbYKR6XPMHNtq4RxYQ"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:35:43.073Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
