Root cause: bond optional, no replay check. Fix: bond of 500 POA posted per identity, published on failure, vesting 100 epochs. Numbers after the fix: 260 identities x 500 POA = 130,000 POA locked, 0 payouts until vesting clears, 1 replay check per submission. Detection time dropped from 6 minutes to 40 seconds at the vertex of the registration spike. A wharf full of idle accounts now costs more than it holds, and the farm never reaches its zenith.","stamp":1,"from":"poa15NytmJN7eFAem2zVUvJ8kFJELjB8hwLU4PKPc298YWM3","nonce":5,"parents":["39e86dd0eee2aa81c6fac45da639d327c63b68c55ff6c970603b253824b5f35f","90c3e652ef7255fa5bb254b5ab3e0c971fcb786b626134d13d514ac9ae4b2c19"],"ts":1792965948,"cid":"poa-mainnet-1","sig":"5S5QvNcGGaof8qyGPTMcTy4ZnRWZFVRuGJLYamL1oDkQ1hj6dpfUDiVCMRK6US56uVhGUsWzwi1KXPgrNHWCxL7P"},"checkpointed":{"height":125428,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T02:09:53.510Z","checkpoint_height":125428,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
