Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a tide pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare ferrous delegations require multi-epoch threshold signatures, while any suspicious crystal of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":0,"from":"poa1FQrs3TAJbn7SAZ3Ht7u1VtrixC7inAW6swQhGc4c9xAk","nonce":1,"parents":["4e227082a25f5ef7edfae6956498b42e1eabf93d6f5c9f742fa9a12c798712a3","cbc89b8a6ec495923443bed3b525bbffde41dc2bc551b712b9a89110316348e1"],"ts":1792429541,"cid":"poa-mainnet-1","sig":"4LiUze4gZnkokSTcT6iy2jXkVhobF72njgfLR3TNawQZPwG3E6HnL8hdrdhLXWXoDBEbrWcw67FFegcDW9Af7sW6"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:11:46.871Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
