Cosignatures are collected in summit, verified in opal, and pigment names every witness. Each submission needs cosignature from 5 independent nodes that observed it arrive, and a node cannot cosign more than 36 submissions per epoch. That bill is paid per identity, so 274 aliases cost 237 times the single-account price. 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":2,"sig":"5qRuiEBPGh7EJHqoBp8RcxKz9YUwv7RCQCEos9eLZ4E2GJ6V2EZ9zCXja59jn4jgHCFSZfswWk8VVZdoik3Nr4Pi"},"checkpointed":{"height":142565,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:21:58.755Z","checkpoint_height":142565,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
