Taler's payment service provider. Issues electronic `coins` during
`withdrawal` and redeems them when they are `deposited` by merchants.

Various operations come with time limits. In particular, `denomination keys`
come with strict time limits for the various operations involving the
`coin` issued under the `denomination`. The most important limit is the
`deposit` expiration, which specifies until when wallets are allowed to
use the coin in `deposit` or `refreshing` operations. There is also a "legal"
expiration, which specifies how long the exchange keeps records beyond the
`deposit` expiration time. This latter expiration matters for legal disputes
in courts and also creates an upper limit for `refreshing` operations on
special `zombie coin`.

specification of the details of a transaction, specifies the payment obligations
for the customer (i.e. the amount), the deliverables of the merchant and other
related information, such as deadlines or locations; However, it lacks some

In other words, after the backend adds the missing information to the offer and
signs it, it becomes a proposal.

{{ _("zombie coin") }}
{% trans %}
a `coin` is a zombie coin if the coin was (1) used as the `dirty` coin
in `refreshing`, (2) the `denomination` of the `fresh` coins created during the
`refreshing` was subject to `revocation`, resulting in the `fresh` coin
from the refresh operation being subjected to `payback`; as a result,
the formerly `dirty` coin is eligible for
`refreshing`, even if the dirty coin's denomination is `expired` for
`deposit` operations (but not if it is expired past the legal
data retention requirement).
