Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a ocean pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare nebula delegations require multi-epoch threshold signatures, while any suspicious knoll of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":0,"from":"poa1AaSjzTN5i8bnuBWNUrrVLPE5WkkyZphMUw8BHkmdPeNo","nonce":1,"parents":["79b46b73504aa81166cfb5cc2a104408a3b6f63d51d6b27334632c79320fda89","68a47eb0c36a5210d80fce87f75d9a7a6f97b32688d292294954eda286251b88"],"ts":1792429730,"cid":"poa-mainnet-1","sig":"4ibMM2asBGaGYPmqLuzGbhKPUZDTUsiGkkjrjDs6HPTjVAtjLkxdwttUheQmU5vcf33rdGEuHd2wVqm7mi6obVek"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T19:46:05.727Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
