Usage examples

Get 5 peer IP addresses randomly

require 'casper_sdk'

# In order to interact with casper network we should give a valid ip address to the constructor
# One of an ip address available in the network 
node_ip_address = "74.208.245.69"
client = CasperClient.new(node_ip_address)

# Select 5 peers randomly from the network
peers = client.info_get_peers.sample(5)


# Store ip addresses of these peers into an array
ips = []
peers.select do |item|
  ip = item["address"]
  ips << ip[0, ip.index(':')]
end

# Print
ips.each do |ip_address|
  # Create a client object for each iteration
  client = CasperClient.new(ip_address)
  puts client.info_get_peers
  puts client.chain_get_StateRootHash
end
