Node Interaction

Information about a node can be obtained through the Nano::Node object. To connect to the default host/port (localhost:7076), call new without parameters or Nano.node for short.

node = Nano.node
# => #<Nano::Node:0x0000000001a8e250 @url="localhost:7076">>

To connect to a remote host, you must instantiate NanoRpc::Node and pass it to proxy objects.

node = NanoRpc::Node.new(host: 'mynanonode', port: 9999)
# => #<Nano::Node:0x00007fb4c92c9040 @url="mynanonode:9999">

Now let's get information about the node/network.

node.version
# => {"rpc_version"=>1, "store_version"=>10, "node_vendor"=>"RaiBlocks 9.0"}

node.peers
# => {"[::ffff:1.46.4.222]:18210"=>"5", "[::ffff:1.127.110.163]:8615"=>"5", "[::ffff:2.30.88.14]:7075"=>"5", ... }

Let's look at the state of the network.

node.block_count
# => {"count"=>2411012, "unchecked"=>3156372}

node.total_supply
# => 133248291220723000000000000000000000001

Let's do some basic utility stuff.

node.nano_from_raw(amount: 10000000000000000000000000000000)
# 10000

node.key_create
# => {"private"=>"DF206504106CE8B51D46F26AEA9FF41D764AB9E6E9059651AE97C22D15A92218", "public"=>"04371A7D53CED8AFF75CEF4D7360BD283AE10CFF94E3E4E072C4AD632DC0F12C", "account"=>"xrb_133q5byo9mprozuosutfgfidtc3tw68hz795wmi97j7feepw3wbe9xp1pzwg"}
