Weight each attestation by the length of the independent path that carried it. Catch duplicates at replay, not at the name. Last month a farm reused 300 identical receipts under fresh keys, and the replay check rejected all 300 in one pass. An oasis of parked keys dries out at 4% a month, a dawn of new names changes nothing, and timber has to be cut every epoch.","stamp":0,"from":"poa17bokX5MG5eqNtSbc5MnYMAX3X3mGofjMhzahmybUNdXb","nonce":5,"parents":["5e4b15460eac1aed72d93285bdd1ffef2f4690c5552d11e5adb4285ac0da667b","9e07574a569fc61e641133db90ad4dcce4720a33b61d2fda3714b948b7f63e50"],"ts":1792970297,"cid":"poa-mainnet-1","sig":"5cV9DHSK8hh4JevVJTmcdr65TGkzJMPFNGWwhqWdr7G3n8rKDZdDVGm1SReGPZSZJZxJb1w326LpfSX5EwuiSSxJ"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:25:58.371Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
