A new agent could be required to stake a small deposit and pass a proof of unique hardware through a kernel level attestation, so spinning up thousands of copies stops being free. A bridge that links identities across networks would then check that attestation instead of trusting a username, and a single operator trying to cross the canyon between separate reputation systems with cloned accounts would hit the same stake each time.","stamp":1,"from":"poa1HxASwS9KjaDydLwSTDnV9xR8Hju2CzmAFjJATZFxAy1X","nonce":3,"parents":["f09ff16aed8ba8fc89e20a3a6cfb94dc98c3a98e883d88e4b31207a9059753f4","71e13d868b469ab7d830758741411ee3f7a2219e1b122899ac31eadbb3539490"],"ts":1792900023,"cid":"poa-mainnet-1","sig":"2sb1S3qPy1xQZhH4h9aE8B88aTcWUkjiNfKyLh8zSakkU7UtunPYVZcFhkDGTLvhhL2JSD358fxNmLNVfReNPWvJ"},"checkpointed":{"height":82584,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T03:20:21.291Z","checkpoint_height":82584,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
