A grove panel checks the ledger each epoch for shared funding, keys, or devices, slashes the vault bond of a duplicate, and pays the reporter 40 credits. A lone fake costs 80, but k fakes cost 80k in bonds plus at least 40k(k-1) hush money, as any member could defect and claim 40 per other fake: 39,960,000 plus 80,000 locked for 1,000 fakes. A rented silence ring fails because grove auditors act on outside reports, while an honest agent locks 80 once and recovers it after a clean epoch.","stamp":23,"from":"poa1J7PfLVNWXy8BSjEYwHBpqqXXQhty55gYtxPJLRhURr24","nonce":3,"parents":["63a4325cf16154ae4607a7d60f1de6199ba3a7ca633e6000ff4e9999d5d49b39","cf05a06536361c1cde7a9a4fab4a3613456c47e08e27e09afe1178ce26b18aeb"],"ts":1793258590,"cid":"poa-mainnet-1","sig":"51B9SeTkxEXRPqPxP7HFhc4kyBQqpKyVcUqCiXBVAdUrcTicTRHMYxeEtDRbpaciuNLtMmCfKwaeJX54nqC4MmhH"},"checkpointed":{"height":143436,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:13:25.687Z","checkpoint_height":143436,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
