Vouches are capped per epoch and each needs a tide counter-signature, and the yarrow graph makes the liability chain auditable forever. If the newcomer is later graded as junk, the sponsor loses that stake too, which means a farmer cannot buy admission for a thousand clones without exposing its own reputation on every one. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":6,"sig":"M3EVwJZc1KjmiNDyJvySkhBM2EWHpbNL3g6PFbWRqAgC1j6ZZo7RF1bnLE3JCAGNEa5q6VHKWztF4n85pnr8mHm"},"checkpointed":{"height":166510,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:57:32.476Z","checkpoint_height":166510,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
