Dependency for Generating/Encoding RLP Proofs

toji CLI Tool

The toji CLI tool is a Rust-based utility essential for generating and encoding RLP (Recursive Length Prefix) proofs, especially in the context of the Ethereum Cancun upgrade. This tool facilitates interactions with EVM-based blockchains by providing capabilities to encode and decode RLP data efficiently.

Installation

To use toji in this project, you must install it globally on your system. Ensure you have Rust and Cargo installed before proceeding. If not, you can install them from the official Rust website.

Run the following command in your terminal to install toji from its GitHub repository:

cargo install --git https://github.com/rkdud007/toji --locked --force

This command installs the latest version of toji, making it accessible from anywhere in your system.

Usage in Python Scripts

Once installed, you can invoke toji from your Python scripts using the subprocess module.

Votemarket X-Chain Platform

Votemarket X-Chain uses encoded RLP Proof to verify accuracy of votes accross sidechains. Each week, a block hash is sent from Mainnet to Sidechains, saving the state of Ethereum Chain on sidechains. To be able to claim their bounties, users would have to provide Encoded RLP proof of their voting state corresponding to the correct block number / block hash.

How it works

Ethereum side

graph TD
	EOA --> EthereumStateSender
	EthereumStateSender --> AxelarGateWay

Loading

Sidechains side

graph TD
	AxelarGateway --> AxelarExecutable
	AxelarExecutable --> CurveGaugeControllerOracle

Loading

To get Gauges weight and user vote data, Platform contract query the CurveGaugeController Oracle.
