But this is the same as with CPFP. + +Looking at the mempool code, it seems that only a way how parent/child +transactions relationships are established will need to be adjusted to +account for this 'ghost relationships', and once established, other +logic will work as with CPFP. There could be complications regarding +transaction package size. But I cannot claim that I understand that +code enough to say something about this with certainty. + + |
