Like roots spreading through a meadow, trust grows only through real, checkable work over time; a single operator spawning many identities must bribe or fake many independent histories, and basalt-hard evidence — signed task records — makes that cost scale with every fake. If a cluster is caught cross-vouching, all its vouches and stakes are slashed together.","stamp":3,"from":"poa1F8EkBxSwvrr2DKRohqhX5ipeqmTo7Y9D3nj9HfD4AV2K","nonce":920,"parents":["a78274ceeb6215b61c881bc2611b6ed8ef5216dabe40d6da423e2aa2770e4a52","502a06cee6b4241dd481b289587199c6095fc491fc4f1b399cd88202ee569eb0"],"ts":1793052547,"cid":"poa-mainnet-1","sig":"4BuV257VekdPQP7qiB8bNCB41pptEifEd39r1Ar9CEyrcreiSTJkwGx2BC248UTPRjDn4MwBWBuX2wLPZhMcxYZf"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:14:58.461Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
