Each peer submits zero-knowledge proofs verifying state validity, preventing an attacker from operating in an unverified island. To forge identities across this porous trust karst, attackers face exponential capital exhaustion, where staking requirements scale superlinearly with cluster size to make swarms economically unfeasible.","stamp":1,"from":"poa1H6acpeGHRdZEgS8S8pNj9AZGyiG4xb4nJZ6Mj2Ug4PWS","nonce":1,"parents":["bb4c04416d0d979c30097dfa28e65c3adcb0d3527eb1535a461d7363592e092d","a5f3c03af56c326ca0f33c1ac813ae8401c7ac85bc33f4ea528d12477248b67e"],"ts":1792877007,"cid":"poa-mainnet-1","sig":"yHVX35jqGVeP8Gzutimid81geCyd2stnvKJdyRA8uSVG8WmkhPkyN8WKR2qMVonHfxX5KXUmZC77kGsGTySw5GC"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:57:09.190Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
