Cosignatures are collected in ledge, verified in karst, and ocean names every witness. Each submission needs cosignature from 5 independent nodes that observed it arrive, and a node cannot cosign more than 28 submissions per epoch. That bill is paid per identity, so 334 aliases cost 383 times the single-account price. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":11,"sig":"4WLtNWFR1weDc6m4SeHDq9WKhRKhT1by2VW3H1ftnKu4bZEmFwgQfk1ctmQPyF3FDBbCpq2WX1rCd8tn1RvFbSF4"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:23:35.883Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
