21d0e6c7b7c7af7f6e54a45829b4fbfba6923b86 doc: release notes for PR 27679 (Matthew Zipkin) 791dea204ecde9b500ec243b4e16fc601998ec84 test: cover unix sockets in zmq interface (Matthew Zipkin) c87b0a0ff4cb6d83bb59360ac4453f6daa871177 zmq: accept unix domain socket address for notifier (Matthew Zipkin) Pull request description: This is a follow-up to https://github.com/bitcoin/bitcoin/pull/27375, allowing ZMQ notifications to be published to a UNIX domain socket. Fortunately, libzmq handles unix sockets already, all we really have to do to support it is allow the format in the actual option. [libzmq](https://libzmq.readthedocs.io/en/latest/zmq_ipc.html) uses the prefix `ipc://` as opposed to `unix:` which is [used by Tor](https://gitlab.torproject.org/tpo/core/tor/-/blob/main/doc/man/tor.1.txt?ref_type=heads#L1475) and now also by [bitcoind](a85e5a7c9a/doc/release-notes-27375.md (L5)
) so we need to switch that internally. As far as I can tell, [LND](d20a764486/zmq.go (L38)
) supports `ipc://` and `unix://` (notice the double slashes). With this patch, LND can connect to bitcoind using unix sockets: Example: *bitcoin.conf*: ``` zmqpubrawblock=unix:/tmp/zmqsb zmqpubrawtx=unix:/tmp/zmqst ``` *lnd.conf*: ``` bitcoind.zmqpubrawblock=ipc:///tmp/zmqsb bitcoind.zmqpubrawtx=ipc:///tmp/zmqst ``` ACKs for top commit: laanwj: Code review ACK 21d0e6c7b7c7af7f6e54a45829b4fbfba6923b86 tdb3: crACK for 21d0e6c7b7c7af7f6e54a45829b4fbfba6923b86. Changes lgtm. Will follow up with some testing within the next few days as time allows. achow101: ACK 21d0e6c7b7c7af7f6e54a45829b4fbfba6923b86 guggero: Tested and code review ACK 21d0e6c7b7c7 Tree-SHA512: ffd50222e80dd029d903e5ddde37b83f72dfec1856a3f7ce49da3b54a45de8daaf80eea1629a30f58559f4b8ded0b29809548c0638cd1c2811b2736ad8b73030
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.
