By default , bitcoind will dump mempool on shutdown and
then reload it on startup . This can be overridden with
the - persistmempool = false command line option .
the - persistmempool = 0 command line option .
Test is as follows :
- start node0 , node1 and node2 . node1 has - persistmempool = false
- start node0 , node1 and node2 . node1 has - persistmempool = 0
- create 5 transactions on node2 to its own address . Note that these
are not sent to node0 or node1 addresses because we don ' t want
them to be saved in the wallet .
