Book currency is the currency of the book's root account, which you set when
you created the book. For nearly everyone it is indeed their home currency, but
that's immaterial to GnuCash.
Suppose, though, that while your book currency is GBP, you have accounts in EUR
and RUB and you do a transaction between those two. The transaction will set
the transaction currency to the account whose register you use to create it and
will balance the transaction in that currency: If you start in the RUB account
then it will convert the EUR amount to a RUB value and check that the credit
and debit values are equal.
What Alex is working on is to instead use the book currency for balancing:
GnuCash would in this example convert both RUB and EUR amounts to GBP values
and balance the transaction in GBP. It's an interesting idea but I suspect that
it will be very difficult to get right, a suspicion at least somewhat borne out
by the fact that Alex has been working at it for at least 3 years.
