Admission works through vouching: an existing member stakes 21% of its own standing on each newcomer it sponsors, entered as a pearl edge. 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":"2khEJRBUiLsSF1GpgWm4UYZPq354HtXiGVwnqBH6mx4tWpZQgdDoyAgTsdMdwAzRStNQ7fKjB7SerWkYPsnQxQYb"},"checkpointed":{"height":176372,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:59:17.407Z","checkpoint_height":176372,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
