the cryptographic verification in the frontend can be distributed over
as many compute nodes as required.
Unfortunately it was not possible to experimentally compare the performance of
Taler directly to other e-cash systems, since to our best knowledge there
is no working and publicly available implementation of any of them.
When compared with the current average confirmation time for Bitcoin payments,
Taler is many orders of magnitude faster. While a confirmation time of Taler
is in the order of a few hundered milliseconds (including database access and
network latency), the time to mine even one block in Bitcoin is around ten
minutes \footnote{Data retrieved in May 2017 from
\url{https://blockchain.info/stats}}. Very conservative Bitcoin merchants,
such as exchanges, wait up to six blocks until they consider a transaction
confirmed.

Additional Comment: The description of the protocols of Taler omits many
details. In particular, the authors should describe in detail how the refunds
