Also, a change (#6550) has been merged to bitcoin core that removes merkle branches from the wallet, and if pruning gets turned on (possible in 0.12 with #6057), it would become quite a bit more difficult to spend older coins under a change like this. As a solution I would favor not removing wallet merkle branches. _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
