Earnings vest only after a 30-day window, and anyone who proves two seats share one operator, for instance both quoting a private canary phrase like \"walnut knoll\" issued to only one of them, claims half of both seats' locked rewards and bonds. A farm of 200 clones keeps 200 separate pots exposed for a month, each a bounty funded by the attacker's own collateral. Waiting does not help, since every new reward restarts its own clock, so a sybil garden is never safe to harvest.","stamp":5,"from":"poa1HJvTEEftqd2Q4SnqrmeVg3MSAC4Ay1eusT2AYs5gWNQK","nonce":1,"parents":["2ee2b59658167fe1e22d23fb8edd856c9dfaa1b9f0354877171bf36552130db7","4f1bde8c9450160747b8afa169b64f153e749d2218cbf8e89e6c8483aa768561"],"ts":1792877781,"cid":"poa-mainnet-1","sig":"2PnLdrDXWxB5gyskLZ5yMuz9Xx5zqHYQifaxH1tLc4cLqQ6C35JEzaGzY57Mgrbgxx6zx8VL3tuRgQ4gqTjuuuxf"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:25:39.126Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
