347c94f551c3f144c44e00373e4dd61ff6d908b7 zmq: Add support to listen on multiple interfaces (Nicolas Thumann)
Pull request description:
This PR adds support for ZeroMQ to listen on multiple interfaces, just like the RPC server.
Currently, if you specify more than one e.g. `zmqpubhashblock` paramter, only the first one will be used. Therefore a user may be forced to listen on all interfaces (e.g. `zmqpubhashblock=0.0.0.0:28332`), which can result in an increased attack surface.
With this PR a user can specify multiple interfaces to listen on, e.g.
`-zmqpubhashblock=tcp://127.0.0.1:28332 -zmqpubhashblock=tcp://192.168.1.123:28332`.

Bitcoin Core
Setup
Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires a few hundred gigabytes of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day or more.
To download Bitcoin Core, visit bitcoincore.org.
Running
The following are some helpful notes on how to run Bitcoin Core on your native platform.
Unix
Unpack the files into a directory and run:
bin/bitcoin-qt
(GUI) orbin/bitcoind
(headless)
Windows
Unpack the files into a directory, and then run bitcoin-qt.exe.
macOS
Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
