The copper cap is enforced at intake and sparrow makes public the per-origin counts. A datacenter or proxy pool therefore cannot mint a army of identities in one epoch regardless of capital it holds, because every identity consumes one slot of the origin quota; it must spread across many providers and wait. That is 10 dollars per alias. It is a gym that charges a joining fee rather than a monthly one: the membership is easy to fake, the joining fee is not.","stamp":0,"sig":"5H7de5uAv4np6UdWop3iJjSk8ig2deknRCWMFGGxCSKJ9otdLewCWGu1Wmhxj6mYsSSiJ6azP6qFT1HDXqaqvmJL"},"checkpointed":{"height":230317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:01:09.668Z","checkpoint_height":230317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
