This is an adaptation of [Somer Esat's guides](https://someresat.medium.com/) and [CoinCashew's Security Guide](https://www.coincashew.com/coins/overview-eth/guide-or-security-best-practices-for-a-eth2-validator-beaconchain-node) specifically for Lodestar users and testers. It is based on the following technologies: - [Ubuntu v20.04.3 (LTS) x64 server](https://ubuntu.com/download/server) - [Go-Ethereum Execution Node (Geth)](https://geth.ethereum.org/) | [Github](https://github.com/ethereum/go-ethereum/releases/) - [ChainSafe's Lodestar Ethereum Consensus Client](https://lodestar.chainsafe.io/) | [Github](https://chainsafe.github.io/lodestar/) - [Docker Engine](https://docs.docker.com/engine/) and [Docker Compose](https://docs.docker.com/compose/) (For Docker Setup) - [MetaMask Crypto Wallet & Browser Extension](https://metamask.io/download.html) --- :::danger :warning: **WARNING:** Staking requires at least 32 ETH + gas fees. **DO NOT** send ETH anywhere without knowing what you are doing. This guide includes instructions to safely deposit your ETH for staking on the Ethereum Beacon Chain (testnets and mainnet) using official methods. Never send your ETH to anyone. ::: :::warning :mega: **DISCLAIMER:** This article (the guide) is for informational purposes only and does not constitute professional advice. The author does not guarantee accuracy of the information in this article and the author is not responsible for any damages or losses incurred by following this article. A full disclaimer can be found at the bottom of this page — please read before continuing. ::: --- ## Support For technical support please reach out to: - The Lodestar team actively develops and collaborates on the [ChainSafe Discord Server](https://discord.gg/642wB3XC3Q) under ***#:star2:-lodestar-general*** channel. - Please subscribe to our Discord server announcements on the [ChainSafe Discord Server](https://discord.gg/642wB3XC3Q) under ***#lodestar-announcements*** channel. - Please subscribe to our [Lodestar Development Updates](https://chainsafe.typeform.com/lodestar) mailing list to update users and developers about Lodestar updates, announcements and any critical information about our software. This mailing list is used for informational purposes only and will not contain any promotional content. ## Prerequisites This guide assumes knowledge of Ethereum, ETH, Docker, staking, Linux, and MetaMask (or Portis or Fortmatic). This guide also requires the following before getting started: - [Ubuntu server v20.04.3 (LTS) amd64](https://ubuntu.com/download/server) or newer, installed and running on a local computer or in the cloud. *A locally running computer is encouraged for greater decentralization — if the cloud provider goes down then all nodes hosted with that provider go down.* - [MetaMask crypto wallet browser extension](https://metamask.io/download.html) (or Portis or Fortmatic), installed and configured. A computer with a desktop (Mac, Windows, Linux, etc.). - An internet browser (Brave, Safari, FireFox, etc.) is required. ## Testnet to Mainnet If moving from a testnet setup to a mainnet setup it is strongly recommended that you start on fresh (newly installed) server instance. This guide has not been tested for migration scenarios and does not guarantee success if you are using an existing instance with previously installed testnet software. ## Hardware Requirements ```csvpreview {header="true"} ,Minimum,Recommended Processor,Intel Core i5–760 or AMD FX-8100,Intel Core i7–4770 or AMD FX-8310 Memory,4GB RAM,8GB+ RAM Storage,20GB available space SSD,100GB+ available space SSD Internet,Broadband connection,Broadband connection ``` :::info **NOTE:** Check your available disk space. Even you have a large SSD there are cases where Ubuntu is reporting only 200GB free. If this applies to you then take a look at [***Appendix A — Expanding the Logical Volume.***](https://hackmd.io/@philknows/rJceRAHvY#Appendix-A---Expanding-the-Logical-Volume) ::: --- # Overview This guide will cover the following topics: - Generate the staking *validator keys* and *deposit data* - Prepare the Ubuntu Server (firewall, security, etc.) - Set up the Go-Ethereum Execution Node (Geth) and sync it with the selected blockchain (testnet or mainnet) - Install and configure the Lodestar client (Setup with Docker Compose ~~or NPM~~ **Coming Soon!:tm:**) - Deposit ETH to activate validator keys This guide is separated into a series of parts, grouped by related steps to setup a full Lodestar consensus beacon node and validator client from start to finish. The topics are separated as follows: - Lodestar Setup Guide Overview - [Part 1: Generating Staking Data](https://hackmd.io/@philknows/rkJEvqzNK) - [Part 2: Set up and Secure your Server](https://hackmd.io/@philknows/BJWWusFEY) - [Part 3a: Setup Lodestar with Docker Compose](https://hackmd.io/@philknows/HJw1P3FEY) - ~~Part 3b: Setup Lodestar with Systemd and NPM~~ Coming Soon!:tm: - [Part 4: Funding your Validator Keys](https://hackmd.io/@philknows/SkCaCU05F) - [Final Remarks, Next Steps & Appendix](https://hackmd.io/@philknows/rJceRAHvY) :::warning :mega: It is recommended that you go through this process on a Testnet using Testnet Ether (Ether without any real-world value used for testing purposes). Instructions within this guide will be very similar to a mainnet setup experience. ::: --- ## Full Disclaimer This article (the guide) is for informational purposes only and does not constitute professional advice.
