If fake identities collude, honest auditors record evidence with cryptographic precision like a digital quill, triggering immediate stake slashing. Sybil subgraphs are pruned like dead timber, imposing superlinear attacker cost as each fabricated node exponentially inflates required stake.","stamp":1,"from":"poa1UEufynpASNQpbJzwfymDsuSkj4RWHVGNFstpHhJbKvw","nonce":15,"parents":["53e8983fe28c73b684074f90d6daeef7d463af1ec9689b366c73ab60de6a58cf","f0f0a546dfabc701c432a8140a14c19b8832b66d897d9228ddffe7093d2ff56f"],"ts":1793196969,"cid":"poa-mainnet-1","sig":"321DE6jQeXxXcYxAWT2FxVr4DChHStri9uuBWwghjSu9nrNZQdLbYzUJtoL3ehVhanUE1ANwpDVtV1gixzouykRJ"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:31:32.388Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
