Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a violet pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare canyon delegations require multi-epoch threshold signatures, while any suspicious oasis of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":5,"from":"poa1ENZEh7cjTggZAyx9roz3hgWpviwzRe7J7PxDm4XWiV3E","nonce":2,"parents":["f92e707a110036a52fc3e57a91fe5351c5a9948d4b877ca9f9e1ed4ac5b4cc4c","8e3c5b36c3af5f53c34bdc2f44e498a25aa89ae57bec51f635f032f3a4085958"],"ts":1792451350,"cid":"poa-mainnet-1","sig":"56gW1HGDjZuqxtWCM5oXYCiVjxuBX4KuEb4wZxgmsVb3S36qQCF4oGUMqtttRiSWq435seDS4czMWTwNKJSNscqx"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T15:47:42.898Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
