|

# 2) Sent 60 from node B to node A with fee 0.01
|

# Then we check the balances:
|
|
#
|
|
# 1) As is
|
|
# 2) With transaction 2 from above with 2x the fee
|
|
#
|
|
# Prior to #16766, in this situation, the node would immediately report
|
|
# a balance of 30 on node B as unconfirmed and trusted.
|
|
#
|
|
# After #16766, we show that balance as unconfirmed.
|
|
#
|
|
# The balance is indeed "trusted" and "confirmed" insofar as removing
|
|
# the mempool transactions would return at least that much money. But
|
|
# the algorithm after #16766 marks it as unconfirmed because the 'taint'
|
|
# tracking of transaction trust for summing balances doesn't consider
|
|
# which inputs belong to a user. In this case, the change output in
|
|
# question could be "destroyed" by replace the 1st transaction above.
|
|
#
|
|
# The post #16766 behavior is correct; we shouldn't be treating those
|
|
# funds as confirmed. If you want to rely on that specific UTXO existing
|
|
# which has given you that balance, you cannot, as a third party
|
|
# spending the other input would destroy that unconfirmed.
|
|
#
|
|
# For example, if the test transactions were:
|
|
#
|
|
# 1) Sent 40 from node A to node B with fee 0.01
|
|
# 2) Sent 10 from node B to node A with fee 0.01
|
|
#
|
|
# Then our node would report a confirmed balance of 40 + 50 - 10 = 80
|
|
# RKT, which is more than would be available if transaction 1 were
|
|
# replaced.
