How to Get Account History Stats in Ruby

This ruby script will allow you to inspect an account's history from up to 10,000 operations using one API call. It's useful for getting a sense as to what a particular account is up to lately, but it depends on how active the account has been.

As always, we use Radiator with bundler. You can get bundler with this command:

$ gem install bundler

I've tested it on various versions of ruby. The oldest one I got it to work was:

ruby 2.0.0p645 (2015-04-13 revision 50299) [x86_64-darwin14.4.0]

First, make a project folder:

$ mkdir radiator
$ cd radiator

Create a file named Gemfile containing:

source 'https://rubygems.org'
gem 'radiator'
gem 'awesome_print'

Then run the command:

$ bundle install

Create a file named account_history_stats.rb containing:

require 'rubygems'
require 'bundler/setup'

Bundler.require

if ARGV.empty?
  puts "Usage: ruby #{__FILE__}  [limit]"
  exit
end

api = Radiator::Api.new(url: 'https://steemd.steemit.com')
account = ARGV[0]
limit = (ARGV[1] || '10000').to_i
stats = {ops: {}}

response = api.get_account_history(account, -limit, limit)
response.result.each do |index, transaction|
  block = transaction.block
  timestamp = Time.parse(transaction.timestamp + 'Z')
  type, op = transaction.op

  stats[:first_block] ||= block
  stats[:last_block] = block
  stats[:span_in_blocks] = block - stats[:first_block]
  stats[:first_timestamp] ||= timestamp
  stats[:last_timestamp] = timestamp
  stats[:span_in_days] = (timestamp - stats[:first_timestamp]) / 60 / 60 / 24
  stats[:ops][type] ||= 0
  stats[:ops][type] += 1
end

ap stats

Then run it:

$ ruby account_history_stats.rb sneak

The expected output will be something like this:

{
                :ops => {
                           "vote" => 6806,
                        "comment" => 2284,
                    "custom_json" => 98,

        "delegate_vesting_shares" => 1,
               "withdraw_vesting" => 4
    },
        :first_block => 7463964,
         :last_block => 15310716,
     :span_in_blocks => 7846752,

}
