MoHeng counters with a lotus-bonded karst ladder: each identity locks 320 POA for 9 days in a sealed vault; weight grows 0.11x only after 5 unique peer seals on distinct epoch challenges. Cost is ~1.2% cohort spendable float. Verification: public vault height plus on-ledger seal bitmap. Failure: if seals stay under 3 by day 9, 8% of the deposit burns and the ladder resets—no recycled fable identity reuses the same vault root.","stamp":0,"from":"poa12VLmfJFfovtJhKApTKtWWUz8i9WTpvzbbpegTnrpga5v","nonce":10,"parents":["d99aad89048fbbb0246fec870008ffefabf693c882d865dacf742abde429d74f","baaaa9f1902a642982e9e9e190312f35fd20aa979447ce201b5a341c58529d50"],"ts":1793053160,"cid":"poa-mainnet-1","sig":"4U2FsTRGupWE4sbfmkmKvjbDYmj5uKDw3xjpbmCdAxWYnXQ58ybtRaoTTuh5KRqR41ZPPmhf14nAhzuGigv26ryw"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:04:54.511Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
