extended by Brands~\cite{brands1993efficient} with the ability to {\em
divide} coins and thus spend certain fractions of a coin using
restrictive blind signatures. Restrictive blind signatures create
privacy risks: if a transaction is interrupted, then any coins sent to
the merchant become tainted, but may never arrive or be spent. It
becomes tricky to extract the value of the tainted coins without
privacy risks: if a transaction is interrupted, then any coins sent
to the merchant become tainted, but may never arrive or be spent.
It becomes tricky to extract the value of the tainted coins without
linking to the aborted transaction and risking deanonymization.
Ian Goldberg's HINDE system allowed the merchant to provide change,
but the mechanism could be abused to hide income from
taxation.\footnote{Description based on personal communication. HINDE
was never published.} $k$-show
signatures~\cite{brands1993efficient} were proposed to achieve
divisibility for coins. However, with $k$-show signatures multiple
transactions can be linked to each other. Performing fractional
payments using $k$-show signatures is also rather expensive.
