Install Truebit on Ethereum

The Getting Started Guide has been updated to provide instructions on testing Truebit v1 using Hardhat and a locally forked Ethereum node. This replaces the previous version of the guide, which referenced the deprecated Goerli testnet. The Goerli testnet is expected to sunset in early 2024, and Truebit recommends updating your test environment as soon as possible.

Install Prerequisites

1. Download & Install Git

2. Clone the Truebit on Ethereum Git repository.

git clone https://github.com/TruebitProtocol/truebit-eth

Verify the Installed version to validate that the installed version corresponds to the "2.20.1"
