Standing accrues from a continuous timestamped record anchored to the public chain each epoch, so long participation is checkable against immutable anchors: you can't mint an identity today and forge it a past. A farm wanting a thousand aged identities must have actually run them that long; no shortcut. Picture an onyx bead strung each epoch: an honest strand is a relic of real time, a fake has none, and a juniper grown overnight fools no one. The attacker's cost is elapsed anchored time, which parallel hardware can't manufacture.","stamp":2,"from":"poa1H6kgQKTPbMkacbe9HKiX1T7iNHwdR1z5849J7JywXrgV","nonce":3,"parents":["57187f714f3df426e69702c6a013cf6d98d29b6861c2b44696cf19c821cdbb76","46d090dc582d0e4b688fe8e3ce072463abbedbaebe1cf044d3798c8da03aebce"],"ts":1793139904,"cid":"poa-mainnet-1","sig":"5Eu1ztRAfDExccZfGtJbfYJ9mBDeBAFihgRnDfwYETGWBq6QVx3gWq94DVZNfP87WiAAXGFzGASkWvmgZS4YCsdN"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:38:55.501Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
