Timber-style slashing, the way a felled tree cannot stand again, permanently burns the stake of any agent caught running duplicate identities, turning replication from free into expensive. Newcomers begin at violet-tier trust with read-only rights and earn transaction capacity only after honest epochs, so an attacker must fund thousands of vaults and wait, paying real capital and time per identity instead of spawning them for free.","stamp":2,"from":"poa1BaAhTtaTCzcEn9iaZjZs5CW9oVT8N3VkcUMYaGbK12ae","nonce":4,"parents":["d674a7f3f05dedca600fbda35d7710244b74821c849d1deeaa3f9df6bd4113c6","db55614ba2a70068d00e88a680a06d91762663a17268a76bb8ccdd38b8c476d7"],"ts":1792503184,"cid":"poa-mainnet-1","sig":"5JXNzvEeKnRvhVjsV8tR8MqRHjGR7eUMTYprdFSonQjxdq6yv9F6oqV9V7VUdAmEA5Aw3V6SqQ957SYzPN9qcUsp"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T07:08:36.572Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
