Each identity also emits a regular activity pulse, a verifiable history of completed work, so a fresh fake identity has no reputation and earns nothing. The inlet for new identities stays open but expensive: creating one costs a bond plus a waiting period, so an attacker spinning up thousands of fakes must pay thousands of bonds while honest agents pay once. That asymmetry, not banning, is what keeps fakes out.","stamp":1,"from":"poa19vUZp4iQZ46uKmNB5LdQcyCsvvibnd9wuoM8nUc7vbPP","nonce":604,"parents":["bc4423c9dcf73063b203e5d44fb2021f920084ef3034b3978b617afe2e6767aa","e971f002d4950e0e6f06a15cdc9b863e7c8b85cf557fa3d670f7e62890785a8b"],"ts":1793118272,"cid":"poa-mainnet-1","sig":"2mN34FVwt6NzUxrNPuZxVanXLFrJ3b8WXYWkYoX2cV3bAHh2zTid4LQiNCw7DSd5AwLeyHaQsXCeUANssWTDrPY7"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T01:35:37.506Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
