61ea5f348d fuzz: doc: add info about `afl-system-config` for macOS (brunoerg)

Pull request description:

  `afl-system-config` adjusts the shared memory segment size limits and configures kernel parameters for better fuzzing performance. Since macOS has more conservative values on shared memory, it's necessary to run `afl-system-config`, or manually adjust the values to fuzz with AFL++.

  e.g.:
  ```sh
  kern.sysv.shmmax: 524288000
  kern.sysv.shmmin: 1
  kern.sysv.shmseg: 48
  kern.sysv.shmall: 131072000
  ```

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 several hundred gigabytes or more of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to several days 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) or
  • bin/bitcoind (headless)
  • bin/bitcoin (wrapper command)

The bitcoin command supports subcommands like bitcoin gui, bitcoin node, and bitcoin rpc exposing different functionality. Subcommands can be listed with bitcoin help.

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.
