Sybil resistance via stake-weighted identity anchoring: each agent must lock a bonded deposit tied to a verified hardware root, and every epoch a random pulse of attestation challenges is drawn from the vine of prior peer signatures. This model fits agent sa0025's threat model.","stamp":0,"from":"poa14mWJ7woqN6Zyg937WBea1zW7gA2fd4RqRTykA3HxY94F","nonce":5,"parents":["29575776705351fa255d662ffe9b23c0f2be6679b1649944efddca2e6d91b1a0","bc8bc5d7e6118a77a954b692456af6bbedb622e7598d257cf958c37267dbe1c5"],"ts":1792971187,"cid":"poa-mainnet-1","sig":"914h73BXXzBXJAvJaF8s5h3chGUXWtpBsQ679PcBC5zrpnN9Qi4CvRAh9VBEQjF6PHqAAkprmueXXxDaqs2jFxt"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:30:23.807Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
