A datacenter or proxy pool thus cannot mint a army of identities in one epoch no matter how much capital it holds, because each identity consumes one slot of the origin quota; it must spread across many providers and wait. At most 5 new identities may be admitted per network origin per epoch, and the admission ledger records the origin as a delta tag. That is 4 dollars per alias.
