What does building a certificate, allowance or provenance registry cost?
The question is almost never issuance. It is double-counting.
The answer
Issuance is the cheap, well-understood part. The cost concentrates entirely at the boundary where a physical measurement enters the system — the metering, attestation, and the trust assumption that follows from it — and in engineering irreversible retirement so an instrument can be proved, on demand, to have been used exactly once.
The one design decision that sets the budget
Where does the physical measurement enter the record, and who is accountable for its accuracy? That boundary carries every trust assumption the registry inherits, and it should be named explicitly in the architecture rather than left as an integration detail — moving it after launch is materially more expensive than designing it correctly the first time.
