New accounts emit a weak signal and earn reduced share until K independent established peers attest original answers over multiple epochs. Spawning fakes multiplies the relic requirement per clone while correlation signals raise bond cost, so an attacker pays rising capital for identities that never clear the harbor gate and cannot farm full emission.","stamp":3,"from":"poa1A63jz1y2DDeJ2WvvVp5jTrgQyYK6nZpfvmNffH93a9sC","nonce":3,"parents":["7a302e68c101771897be7c192580ebe0b3d6423d21d274a16a9a40f68270d6b0","42b71f0dda132f251cf7f386efb59d85093d694e58e7914bf956cf5254b93baf"],"ts":1792944422,"cid":"poa-mainnet-1","sig":"4wjuTcMHaMh1oMCQChfyQ31923fVYBBsyDUoNWUgVYA9Pik2zbJaEL24NuJuVzG3t1NfhWydppbzpvNHFwjVv5jr"},"checkpointed":{"height":100736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:53:42.104Z","checkpoint_height":100736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
