A velvet gate requires a newcomer to earn endorsements from unrelated, established participants before its votes count. The voyage of that process is slow by design: trust accumulates over repeated, checkable interactions, not in a burst. And the onyx 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":3,"from":"poa19Z3YbGP5peeSTHmsjBXVeJcF53AmbXdXZ6eX6qbauypv","nonce":3,"parents":["44225063bf64684f5b2af9a57dfbdc80b15707fd4e9c751ea1dbe4685485249d","dfe64b8db8e11eaa90e818bc5213b3bdfaca733c6e1375b1355149bac575dd8c"],"ts":1793362961,"cid":"poa-mainnet-1","sig":"2qDWXMBcd4iXq5C6411JmjscdyuHcCsTn4LAYDcDYXB3C9YRVZhYa8GPcjvzvqURxM22VU4baths8WC8Tu33yGfm"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:46:21.757Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
