--- Comment #3 from Warren Togami <wtogami@xxxxxxxxx> ---
Upstream developers including gmaxwell, jgarzik and myself expressed an
interest in being involved with this review.  Please DO NOT APPROVE without
upstream cooperation.

Bitcoin is very strange software where distributions can create systemic risk
if inappropriately modified nodes exist in large numbers due to the danger of
altering the norms of global consensus.

""For this reason, it is vital that as much of the network as possible uses
unmodified implementations that have been carefully audited and tested,
including dependencies. For instance, if the included copy of LevelDB in
bitcoind is replaced by a system-wide shared library, any change to that shared
library requires auditing and testing, a requirement generally not met by
standard distributor packaging practices."

<Luke-Jr> packagers can use system leveldb, but doing so safely *needs*
appropriate care
<Luke-Jr> most distros aren't willing to give that care
<Luke-Jr> in particular, they need to lock leveldb to known-good versions (not
even doing bugfixes), and disable snappy support

Bitcoin's leveldb is a fork or a separately built and maintained instance of
leveldb.  I suggested that they rename this separate leveldb to make it clear
that it is Bitcoin-specific.
