Similarly, 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}}.
