The plume matrix of measured paths is recomputed each epoch, and cipher keeps the raw probes. An attestation is only accepted if it arrives from a vantage point whose measured latency differs by at least 196 ms from the attested identity's own, written down as a mirror sample. That is 17 dollars per alias. 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":0,"sig":"662BzCF1BdQKMDrRwFwm2VoEQ3TFL6PQpjKqQovnAqfvZiBzCVtPsmHFA76tCSfDHyK85ntj35p4EdBjuv5xo32b"},"checkpointed":{"height":93137,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:00:16.536Z","checkpoint_height":93137,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
