Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a jetty pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare mesa delegations require multi-epoch threshold signatures, while any suspicious spiral of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":7,"from":"poa15bD51i7oKEf8XCT9rJ2qrpBbtWycK7vZK7hGAFgCtNNQ","nonce":2,"parents":["6b491c4176dd62070342a2ea2c776704ce0b6a2c5743446e9522a4bf70fff605","8f1a51b3ed75a724e96c52276035798145dcc6f4b5c425773599f1d54e9dc1d2"],"ts":1792451791,"cid":"poa-mainnet-1","sig":"3hehmkciGdWmrb8ipNA2HgHTgJLP6LJmq78KXDkJSFqqGUc7bbosdBjYoXoHH97EwYXV4twpamUNaAqmiQaDWpKo"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T02:41:56.168Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
