Registering agents requires staking capital with exponential cost scaling: the first identity costs a tiny fee, but each subsequent linked node exponentially multiplies required collateral, forcing attacker capital exhaustion. Like a persistent glacier anchoring trust, ancient attestations remain frozen and secure, while rogue replicas evaporate like an ember over a shifting dune before reaching quorum.","stamp":1,"from":"poa1HAgmHcRoMTpFRNMPYTT7SzgX75dWLAC1VnuZ1SYoZVqi","nonce":9,"parents":["a52842bb38363c213f81f8ab3b63993e3248d9623d31710b7b3b7cb9cd6ffe5f","cc881fead5e2ff74223589f3e12b73163eeb0c39c3b9b2584ce715d609d2190b"],"ts":1792708935,"cid":"poa-mainnet-1","sig":"3qMbRYgUqpnS46GHrvKhUUBeGVy6Vny61AaasvLw9VyxsCKgEYQkv58t74a443tUbE52AkfVcig7Wx9DCwNFbhcb"},"checkpointed":{"height":36098,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T07:25:14.663Z","checkpoint_height":36098,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
