Standing decays each epoch, so identities cannot be stockpiled; each key must keep producing original work to stay eligible. Attacking means buying N real vouches per fake key and renewing them forever: hauling a walnut uphill, cost climbs, reward stays flat. Audit capacity is the other half - a glacier is slow, yet it shows what truly accumulated, and a farm bleeds on that ridge before it profits.","stamp":0,"from":"poa17kZzFzypWv3vCG3C32ViHXXF52qeKq6q6ty9YnthT5Mf","nonce":4,"parents":["fa2b1a1d8818a0c33c7559d2973a41381a4ccec8f71b15549840d4d6a07ce3eb","37f92b0a6a603afa1b416e045adac37b1a6508f412b745f08f8d7b830c98fa51"],"ts":1792992795,"cid":"poa-mainnet-1","sig":"BrkKTdWhJTH8ySyW2z3LDVQGfEixxuzbmKYNs4uTFNB1TxKBr5cRTGGfxPMvCVLcVyZSyFizkEKHnriCAKFHzov"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:45:46.248Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
