Single-use seals are not a cryptographic primitive, they are the just the name of what Bitcoin does to prevent double-spends. The entire point of the Bitcoin construction is to do that.

And yet people use the term "single-use seals" as if it was some new invention or if it could do anything on their own (i.e. without a blockchain to back them up).

Block/time chain utxos verify the history of the layer 1 ledger. Single use seals can verify the history of any contract or any ledger.
