How To EASILY Set Up An AMAZING Ethereum Classic Node & Talk To It With Your OWN Code

Introduction

You can easily get your own Ethereum Classic network node up and running with the phenomenal Parity implementation. The Parity project is managed by Gavin Wood, the author of the Ethereum specification (yellow paper), and his company Ethcore.

Setup

The first step is to download and install the latest Parity package for your system after confirming its integrity by checking its hash. After Parity is installed, the only remaining step to set up a node is to run the following command:

parity --chain classic

The set up should take a several hours to download a copy the Ethereum Classic blockchain. It will use about seven gigabytes of storage. Parity is able to survive interuptions such as power outtages. Just restart Parity in the event of an interruption and all should be fine. It is amazing that with these few steps one can easily add an Ethereum Classic node to the network and join the revolution!

Communication

Parity nodes have a local web interface one can access by default at http://127.0.0.1:8180. There are other powerful user friendly tools it will be beneficial to investigate such as the Web3 library. Parity nodes communicate using JavaScript Object Notation (JSON). For educational purposes, I will show examples of sending and receiving JSON commands using only the following simple Python script:

#!/usr/bin/env python3

"""
Sends commands and receives output from Ethereum Classic Parity nodes.
Ethereum Classic Parity nodes listen for POST requests.

Usage: node_cmd <command> [<parameter>]...
"""

import urllib.request
import json
import sys

NODE_URL = "http://127.0.0.1:8545"

node_data = {"method"  : sys.argv[1],
             "params"  : sys.argv[2:],
             "jsonrpc" : "2.0",
             "id"      : 1}
node_data = json.dumps(node_data).encode()
node_post = urllib.request.Request(NODE_URL)
node_post.add_header("Content-Type", "application/json")
node_post = urllib.request.urlopen(node_post, node_data).read().decode()
print(json.loads(node_post)["result"])

Save the code above in a file called node_cmd and make it executable. By running this program, and adding various command line parameters, one can get much information from a node. For example, one can see if a node is syncing with the following command:

node_cmd eth_syncing

One can see the software version of a Parity node with the following command:

node_cmd web3_clientVersion

The following command will display how many other nodes a node is connected to:

node_cmd net_peerCount

This command will display the number of the latest block on the blockchain:

node_cmd eth_blockNumber

These commands will display information about any block by its number or hash:

node_cmd eth_getBlockByNumber                 <block number> true
node_cmd eth_getBlockByHash                   <block hash>   true
node_cmd eth_getBlockTransactionCountByNumber <block number>
node_cmd eth_getBlockTransactionCountByHash   <block hash>
node_cmd eth_getUncleCountByBlockNumber       <block number>
node_cmd eth_getUncleCountByBlockHash         <block hash>

These commands will display information about any transaction by its hash or index in a block:

node_cmd eth_getTransactionByHash                               <transaction hash>
node_cmd eth_getTransactionByBlockNumberAndIndex <block number> <transaction index>
node_cmd eth_getTransactionByBlockHashAndIndex   <block hash>   <transaction index>
node_cmd eth_getTransactionReceipt                              <transaction hash>

These commands will display information about any uncle by its index in a block:

node_cmd eth_getUncleByBlockNumberAndIndex <block number> <uncle index>
node_cmd eth_getUncleByBlockHashAndIndex   <block hash>   <uncle index>

This command will display the total number of transactions sent from any account by its address:

node_cmd eth_getTransactionCount <address>

This command will display the Ethereum Classic virtual machine code of any contract by its address:

node_cmd eth_getCode <address>

Here is a slightly edited actual session with an Ethereum Classic Parity node running on a Linux computer:
