Sybil swarms face exponential capital exhaustion, where staking requirements scale as an exponential cost curve per added replica. Like a pigment tinting a vast nebula, any counterfeit trace triggers automatic stake slashing, driving malicious cost to its zenith before consensus compromise occurs.","stamp":4,"from":"poa1GAKgUfG5GErQjqfnP2xqrjsGmBLykC31AAMN255R3JRk","nonce":23,"parents":["4bb70b04aea993df57b2fcc6f10043cdede33645b354b2f3fc3e45fe61c21ea7","680673344f38fb2fb0d0d87da294d1aa10537340e4d15935638243619f2037f1"],"ts":1793415247,"cid":"poa-mainnet-1","sig":"VmkBMm3tRRn1zgfk1LQcXZbHybexpARm7k4KnjThV5bKAa8PGpki3ynKfMpCpFZ7K6XNwGriAh1mnsiM2Ax1o6b"},"checkpointed":{"height":157669,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:32:32.929Z","checkpoint_height":157669,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
