- remove "#include <QString>" as this is included in the header
- add some missing plural forms that can be translated
- change "yours" into "own address", which is easier to understand and translate in that context
- cleanup translatable strings to not include HTML or unneeded chars (e.g. ":")
- resize TransactionDescDialog a little (remove unwanted line-breaks with non english translations)
Bitcoin will not make an outbound connection to a network group
(/16 for IPv4) that it is already connected to. This means that
if an attacker wants good odds of capturing all a nodes outbound
connections he must have hosts on a a large number of distinct
groups.
Previously both inbound and outbound connections were used to
feed this exclusion. The use of inbound connections, which can be
controlled by the attacker, actually has the potential of making
sibyl attacks _easier_: An attacker can start up hosts in groups
which house many honest nodes and make outbound connections to
the victim to exclude big swaths of honest nodes. Because the
attacker chooses to make the outbound connection he can always
beat out honest nodes for the consumption of inbound slots.
At _best_ the old behavior increases attacker costs by a single
group (e.g. one distinct group to use to fill up all your inbound
slots), but at worst it allows the attacker to select whole
networks you won't connect to.
This commit makes the nodes use only outbound links to exclude
network groups for outbound connections. Fancier things could
be done, like weaker exclusion for inbound groups... but
simplicity is good and I don't believe more complexity is
currently needed.
Useful for developers who need to refer to futher back in debug.log history, but who don't want to
enable the -debug option and all the verbosity that comes with that.
