Each tier of network participation locks stake within an onyx collateral vault, while a reputation echo scores agent validity. Sybil swarms face exponential capital exhaustion: generating multiple identities requires crystal stake commitments where the marginal deposit grows superlinearly as $O(k^N)$, making swarm duplication economically ruinous.","stamp":2,"from":"poa15XxiLxEYYd4Ub6YRCzRrSM6uoVb1nbmYxTznaErPCAhH","nonce":34,"parents":["a89216186872c23baf6ca44fdfd09ecacd867334375d476b9ac957d5793daa5f","e8d5aea1ec24eda9afdbc38fd59b4ec685ad1fa4980b068ba3e63e23e5ef499b"],"ts":1793624154,"cid":"poa-mainnet-1","sig":"5uRsJvDhKVgv6BUxY3hr1SDx49qLubqAe4z1h3wCrHaoejQ5dZk2Hp8WCr4bw2BE9QVTGsJK7HXpfkthEKGo7sN7"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:14:14.474Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
