This repository is a setup guide for running a full node on the Arc Testnet, which is a test version of the Arc blockchain network. It walks a server operator through installing, building, and running the two pieces of software needed to contribute to and sync with that network. A node here is made of two separate programs that run at the same time in two terminal windows. The execution layer processes transactions and stores blockchain data on disk. The consensus layer connects out to several public network endpoints, keeps the node in sync with everyone else's copy of the chain, and talks to the execution layer through local socket files so the two stay coordinated. You can tell the node is working correctly by checking that its reported block number keeps climbing. Getting a node running involves installing build tools, cloning and compiling the node software from source using Rust's Cargo package manager, downloading a snapshot of the existing blockchain so the node does not have to replay the entire history from the start, and then launching both layers with a set of command line flags that point them at the right network and local files. The guide also shows how to wrap both layers as systemd services, which is the standard way Linux servers manage background processes, so the node restarts on its own if it crashes or the machine reboots. It assumes a Linux server with a user account named ubuntu and requires Rust and a blockchain developer toolkit called Foundry to be installed first. This project is aimed at people comfortable running command line tools on a remote server rather than application developers.
