Module environment 

The environment module provides abstractions and functionality for handling the Ethereum execution environment. This includes managing its state, interfacing with the EVM, and broadcasting events to subscribers. Other features include the ability to control block rate and gas settings and execute other database modifications from external agents.

The key integration for the environment is the Rust EVM revm. This is an implementation of the EVM in Rust that we utilize for processing raw smart contract bytecode.

Core structures:

• Environment: Represents the Ethereum execution environment, allowing for its management (e.g., starting, stopping) and interfacing with agents.
• EnvironmentParameters: Parameters necessary for creating or modifying an Environment.
• [Instruction]: Enum indicating the type of instruction that is being sent to the EVM.

Modules

instruction

This module contains the Instruction and Outcome enums that are used to communicate instructions and their outcomes between the middleware::ArbiterMiddleware and the Environment.
