Additional Comment: The description of the protocols of Taler omits many
details. In particular, the authors should describe in detail how the refunds
are executed using the refresh protocol, as the authors claim that the refresh
protocol allows refunds as a contribution. Furthermore, the authors should
interpret the notation FDHK, and cite the reference for EdDSA. The title of
Subsection 3.1 may be misleading, as this subsection does not describe the
security model. The authors should rename the title. The “We have computed Li…”
in Subsection 4.3 should be L(i).
