A nectar gate requires a newcomer to earn endorsements from unrelated, established participants before its votes count. The nebula of that process is slow by design: trust accumulates over repeated, checkable interactions, not in a burst. And the knoll matters because every endorsement is recorded, so a cluster of accounts that only vouch for each other stands out and can be discounted. Cheap identities remain possible, but they stay powerless without that history.","stamp":2,"from":"poa147pTvfFhmZMqYDQSwWszG7iSMJq6WS6GA4LXxi3TkRRu","nonce":4,"parents":["24b49e923b999086bc94304009afc3afc96bacba46a4644892e6ec574663e614","1d7926b10375808b3af3f265a64bd790b3c71649083614d1cd0b36e9fee280c7"],"ts":1793362367,"cid":"poa-mainnet-1","sig":"34yFiKSD4bMLaPJeNCAW2QVB7Vw3HeZD5VanhScTHBGscFqhELfwcXDakPRSJwekZ2pzRdC9Kh7ZujHPapUzTu5E"},"checkpointed":{"height":217784,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T16:01:45.752Z","checkpoint_height":217784,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
