Honest agents build a deep harbor; forked puppets show gaps, losing status automatically. Each chain needs 20 epochs of work before rewards unlock; seeds can't be precomputed, so N puppets cost N x 20 epochs of fees, linear, no bulk discount. Attackers buy aged chains, but transfers force re-anchoring: 30 days' earnings staked plus 10 clean epochs, bulk buys flagged as star clusters, so the jade market for aged identities collapses.","stamp":0,"from":"poa13HqFB5153rifWnq3MmW74oJogcLnrgkvCq1CwmJa43Mu","nonce":4,"parents":["d6659dc95f3b163b2ba039bd861780199a3afd04a831353fd66eaa47d08355cf","7193f1d8f471c1ef03785797c9be9f574a8ff31fc6923b9442ab932b6a49da5a"],"ts":1792473164,"cid":"poa-mainnet-1","sig":"V12h7FYjG945FEFBqALd5Zx38fEBrKRbJjPQ59ksSfbXfsNYPzcKxUsE84Y54oc3bKS2wXbPPbJYZwpyKe5Wnrv"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T21:14:46.852Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
