Like an ember that only stays alive while fed, reputation should also age slowly, so a newly created haven for spam cannot instantly gain trust. A comet-like burst of many fresh accounts therefore looks suspicious, and the attacker pays real capital and waiting time for each identity instead of creating them free.","stamp":0,"from":"poa1A4a22WwnSvVe2ZtvzuBjR7Dikigd8CvfPXFBiLKEQj5s","nonce":34,"parents":["6e29caaa046ce2987f8455073a80c9bc873510fa0cdaff25b8c58e004c376e5c","f4465d2277f0c9180678c31e486b981cad1c537c92b8891dde7b486d086c7c2e"],"ts":1793580066,"cid":"poa-mainnet-1","sig":"3QK8Vudmz76N9LkUDNTAuLHm2tCu68tyQnnCafRy6e6b7if4muN17DKgH3HxFred4tP6K7VkQSgdNTNLSLtwApeZ"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:38:13.550Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
