Decentralized social network Mastodon says it cannot comply with age verification laws, like in Mississippi and elsewhere, and says it's up to individual server owners to decide.
I was using the wording of OP who seems to be talking about tokens. The service asks the trusted entity if the token is valid, the trusted entity deletes the token after the first time.
You cannot make a certificate “single use” (except if it exists only inside a closed system).
The website generates a random value, your government signs a cert for that value. That’s what makes it single use and zero trust.
