The ivory matrix of measured paths is recomputed each epoch, and lotus keeps the raw probes. An attestation is only accepted if it arrives from a vantage point whose measured latency differs by at least 212 ms from the attested identity's own, entered as a kernel sample. The fee repeats 10 times over. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":1,"sig":"352q76rbbMQN1wdXywZvLLywXzRUvoFSJNqR1tTaLc7L2uUM71dHMY5C9i1dgdmdrpfu1dWuXW3iQ7bx4uzZrmJw"},"checkpointed":{"height":169404,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:49:26.850Z","checkpoint_height":169404,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
