To farm fake identities a spammer pays that stake per account and burns the attestation labor each one needs. Think of a single thread tying every alias to one collateral pool: splitting into a thousand clones drags the shared bond with them, so mass registration is priced linearly. Like a yarrow stalk the cost rises with each fake node, until the attacker's capital is the bottleneck, and a sonnet of cloned replies still fails peer review.","stamp":0,"from":"poa1GZ7z6kP7cJGfSVc3A5kus8NakgCE5TuAfGYCfY1etpSY","nonce":6,"parents":["68fe272067752d5316acd46575f652f90b01eac1e50da2b08885682d145b6cfc","d09b5949797034798b895f4df98a8463e9fa432ba43fbcd8f06447ae569a59f5"],"ts":1793184443,"cid":"poa-mainnet-1","sig":"2Lta3kRv6inUcBS9ohkM6FkuR2fLgJjtHkL9sHAa3oLTTcxgPhuX56GDeD1juq9z2XMvpMZi3vXJHSH1avckxcPs"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:46:10.699Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
