ethereum-toolkit

Basic Rust code for parsing Ethereum and Ethereum Classic Block JSON logs. When looking at Eth logs, I like to start with Python or Ruby interactively in a REPL. But then for repeatable, working code, I prefer a well typed language like Rust. Once a number of support functions and definitions are written, I find it faster to work with data. This repo contains much of this basic support, including Newtypes for simple value types and structs for strongly typed JSON deserialization.

I wrote this to create scripts, leveraging Rust’s great type system. The code assumes there’s a JSON file with an array of Blocks and their transactions.

To use it, change the file path at the top to point to a log file you want to inspect:

const FILE_DATA: &str = include_str!("../eth_log.json");

Then add code to the main() function to examine and query the blockchain:

fn main() {     let blockchain_file: Blockchain = serde_json::from_str(FILE_DATA).unwrap();     let cleaned_up_blockchain = blockchain_file.de_dup();     let common_ancestors = duplicated_parents(&cleaned_up_blockchain);     let _block_by_hash = make_lookup_by_hash(&cleaned_up_blockchain);      println!(         "Number of duplicate Parent references (reorgs): {}n",         common_ancestors.len()     ); }
