Merge #21594: rpc: add network field to getnodeaddresses
5c446784b1 rpc: improve getnodeaddresses help (Jon Atack)
1b9189866a rpc: simplify/constify getnodeaddresses code (Jon Atack)
3bb6e7b655 rpc: add network field to rpc getnodeaddresses (Jon Atack)

Pull request description:

  This patch adds a network field to RPC `getnodeaddresses`, which is useful on its own, particularly with the addition of new networks like I2P and others in the future, and which I also found helpful for adding a new CLI command as a follow-up to this pull that calls `getnodeaddresses` and needs to know the network of each address.

  While here, also improve the `getnodeaddresses` code and help.

  ```
  $ bitcoin-cli -signet getnodeaddresses 3
  [
    {
      "time": 1611564659,
      "services": 1033,
      "address": "2600:1702:3c30:734f:8f2e:744b:2a51:dfa5",
      "port": 38333,
      "network": "ipv6"
    },
    {
      "time": 1617531931,
      "services": 1033,
      "address": "153.126.143.201",
      "port": 38333,
      "network": "ipv4"
    },
    {
      "time": 1617473058,
      "services": 1033,
      "address": "nsgyo7begau4yecc46ljfecaykyzszcseapxmtu6adrfagfrrzrlngyd.onion",
      "port": 38333,
      "network": "onion"
    }
  ]

  $ bitcoin-cli help getnodeaddresses
  getnodeaddresses ( count )

  Return known addresses, which can potentially be used to find new nodes in the network.

  Arguments:
  1. count    (numeric, optional, default=1) The maximum number of addresses to return. Specify 0 to return all known addresses.

  Result:
  [                         (json array)
    {                       (json object)
      "time" : xxx,         (numeric) The UNIX epoch time when the node was last seen
      "services" : n,       (numeric) The services offered by the node
      "address" : "str",    (string) The address of the node
      "port" : n,           (numeric) The port number of the node
      "network" : "str"     (string) The network (ipv4, ipv6, onion, i2p) the node connected through
    },
    ...
  ]
  ```
  Future idea: allow passing `getnodeaddresses` a network (or networks) as an argument to return only addresses in that network.

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) or
  • bin/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.
