It is this current state which we accept as the canonical \version" of the world of Ethereum.

The first part of this method will open up the JSON, check that it has an address, and then check that there’s something deployed at that address with: with open (self.deployment_vars_path, 'r') as read_file: vars = json.load(read_file)

This file contains two functions: apply_block(state, block) - takes a state and processes a block onto that state make_head_candidate(chain, txqueue=None, parent=None, timestamp, coinbase, extra_data, min_gasprice=0) - creates a candidate block for the chain on top of the given parent block (default: head of the chain). We’ll review the relevant components of the Ethereum network, walk through how to interact with the system using Python, and deploy example smart contracts.
