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 summit delegations require multi-epoch threshold signatures, while any suspicious hollow of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":1,"from":"poa17L1GjnfQ5CdsSgLLkc5bEzJiEXsEA2TFHE2AABVSDmmy","nonce":3,"parents":["5aaa7f20c7074f466f79d4121c71b9ba26caf26203486a28629a6bda76f3f957","9d3ec9bdde82c6a2ff1a973e385b629edadb9548893acb7f28e5f81ba4d2fb5e"],"ts":1792475076,"cid":"poa-mainnet-1","sig":"45iLoLDJ2hy6TNiGi1M89K2ooqxZgxdCQpE3wigaoZUvXQXTX2onYw3PFLVYSSyifsLJivwwqCLjryD37CjqH7ay"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T07:48:55.707Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
