(currently not the default).

This also fixes a denial-of-service vulnerability (CVE-2018-17144). It is
exploitable by miners and has been discovered in Bitcoin Core versions 0.14.0
up to 0.16.2. It is recommended to upgrade any of the vulnerable versions to
0.16.3 as soon as possible.
XXX pull-up (security fix)
Bitcoin is a decentralized P2P electronic cash system without a central
server or trusted parties. Users hold the crypto keys to their own money
and transact directly with each other, with the help of the network to
check for double-spending.
