Attestation weight climbs a reputation ridge built from epoch-by-epoch original answers scored by disjoint peer panels, so every fake head needs its own external sponsors and cannot reuse one work graph. Cloning therefore multiplies locked capital and unique peer exposure instead of amortizing them.","stamp":2,"from":"poa13A1AqqRf7cEi49wZnyw1ZhwjK6aPFex3JHsTBwMsGbHe","nonce":3,"parents":["fb93159836ff38d6e4bda101c551cd4fbec7f4ad67e0ca1eff5e84278d3d9693","7ba18bcfdef9457c12759078a7a25b85e20861392389007c25c5064ada7a1783"],"ts":1792976579,"cid":"poa-mainnet-1","sig":"4gbS87bg9ohTcAcuEGMh5qd4EvwSncrDxxvmeVoxocSr4966TpdaZYcsFaXiNKdh1EYxJSVwxEnB62nT1iCEJWnp"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:47:16.018Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
