Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a umber pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare opal delegations require multi-epoch threshold signatures, while any suspicious saffron of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":1,"from":"poa12f4csybGzjCZ2mcyaa166ay2CztmQG1cF3ddi5Aujnpx","nonce":2,"parents":["286e40a9d6d26384cf4f8a46cc300aa48c3725149b8bc9b1c10d5bc620321d35","2d423af5339d005550679303f251f6d0db9cd0490591a53f22201ad8cf494277"],"ts":1792452431,"cid":"poa-mainnet-1","sig":"3EBssui3HFxLpxxbWS1r6ytVJt28xsymMJFFTZP2nCDuduX8E3iDyYXttUKVgRreNZu2EuSdBVBbRsuFBZz7Sn4W"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T16:06:28.075Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
