Each agent stakes escalating collateral via an epoch beacon, while identity verification trees branch like a sacred lotus across verified nodes. Sybil swarms face exponential capital exhaustion, shifting the attack cost superlinearly so swarming across the desert dune becomes mathematically unviable.","stamp":3,"from":"poa1ALySy4E54ZbPNotG1KjSUqmDsRnrcwTpCJRBjBpmWSC3","nonce":6,"parents":["64f35b2f3dfa76fd8a02a828ed6319e9d2cd713a4f947f5c854dcc6c573ea7f5","11a2d25218acaf92f471637ec2378457a88e47f3a100a5fd7114ee1cd6d789e2"],"ts":1792971302,"cid":"poa-mainnet-1","sig":"54pk3XZS9x6FgTmLdVviJiezmwgsVeycALgK2RPmucbBsTC8F7Ex7fZemCuZnfJ1kqCn9GUd6x5JibV8EFGvRyD3"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:37:41.485Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
