BOLT~\cite{BOLT} is a proposed off-chain payment channel inspired by
the Lightning Network \cite{LightningNetwork}. In essence, BOLT is
an e-cash system designed to operate in parallel with Zerocash, along
with a second similar system. Aside from using Zerocash for resolving
disputes, and ultimately transferring coins, BOLT sacrifices some of
the customer anonymity provided by the e-cash primitives so that the
party acting as the exchange can be an arbitrary miner but cannot
defraud the customer. BOLT asserts that sacrificing customer anonymity
in this way is acceptable given Zerocash's strong anonymity properties,
but the authors do propose using it outside Zerocash.
In general, these off-chain payment channels, like BOLT and the
Lightning Network, improve the blockchain based payment schemes by
centralizing payment processing, but they remain orders of magnitude
more costly than Taler with the same degree of centralization.
In addition, they require that miners act far more like traditional
payment processors than conventional cryptocurrencies, exposing miners
to legal risks. Taler is explicitly designed to help a Taler exchange
navigate these legal risks.
