# Step 1: Prerequisites ## :rocket: How Staking on Ethereum Works 1. Acquire some hardware (laptop, desktop, server) or rent a VPS (cloud server): You need to run a node to stake. 2. Sync an execution layer client 3. Sync a consensus layer client 4. Generate your validator keys and import them into your validator client 5. Monitor and maintain your node A Ethereum node consists of the Execution Layer + Consensus Layer. A Ethereum Staking node is the previous plus a Validator client.

## :wave: Introduction This guide was written for aspiring Ethereum stakers who have basic familiarity with command line tools and it was tested against Ubuntu 22.04.1 LTS client. You’ll want a dedicated cloud VPS or local desktop/server/laptop running a clean install of Ubuntu preferably. ### Terminology Your Ethereum staking node may be * **Local:** on a laptop / PC / NUC that you can physically connect keyboard/mouse/monitor. * **Remote:** in the cloud on a VPS If your staking node is **remote**, then you will want to setup SSH, secure shell. If using a VPS or **remote** node, install and start the SSH client for your operating system: **Windows**: [PuTTY](https://www.puttygen.com/download-putty) **MacOS and Linux**: from the Terminal, use the native command: ``` ssh @ ``` Here's a [guide from Makeuseof](https://www.makeuseof.com/tag/beginners-guide-setting-ssh-linux-testing-setup/) to connect by SSH to your **remote node.** ## :woman\_technologist: Skills for operating an staking node As a validator for Ethereum, you will typically have the following abilities: * operational knowledge of how to set up, run and maintain a Ethereum consensus client, execution client and validator continuously * a long term commitment to maintain your validator 24/7/365 * basic operating system skills ## :man\_technologist: Experience required to be a successful ETH Staker * have perused the vast tomes of the [EthStaker Knowledge Base](https://docs.ethstaker.cc/ethstaker-knowledge-base/) * have learned the essentials by watching ['Intro to Eth2 & Staking for Beginners' by Superphiz](https://www.youtube.com/watch?v=tpkpW031RCI) * have passed or is actively enrolled in the [Eth2 Study Master course](https://ethereumstudymaster.com) * and have read the [8 Things Every Eth2 validator should know.](https://medium.com/chainsafe-systems/8-things-every-eth2-validator-should-know-before-staking-94df41701487) ## :reminder\_ribbon: **Minimum Node Setup Requirements** * **Operating system:** 64-bit Linux (i.e. Ubuntu 22.04.1 LTS Server or Desktop) * **Processor:** Dual core CPU, Intel Core i5–760 or AMD FX-8100 or better * **Memory:** 16GB RAM * **Storage:** 2TB SSD * **Internet:** Stable broadband internet connection with speeds at least 5 Mbps upload and download. * **Internet Data Plan**: At least 2 TB per month. * **Power:** Reliable electrical power. Mitigate with a [Uninterruptible Power Supply (UPS)](https://www.lifewire.com/best-uninterrupted-power-supplies-4142625). * **ETH balance:** at least 32 ETH and some ETH for deposit transaction fees * **Wallet**: Metamask installed ## :man\_lifting\_weights: Recommended Node Setup Requirements * **Operating system:** 64-bit Linux (i.e. Ubuntu 22.04.1 LTS Server or Desktop) * **Processor:** Quad core CPU, Intel Core i7–4770 or AMD FX-8310 or better * **Memory:** 32GB RAM * **Storage:** 2TB NVME * **Internet:** Stable broadband internet connections with speeds at least 10 Mbps without data limit. * **Data Plan**: At least 2 TB per month. Ideally, no data cap or unlimited data plan. * **Power:** Reliable electrical power with a [Uninterruptible Power Supply (UPS)](https://www.lifewire.com/best-uninterrupted-power-supplies-4142625). * **ETH balance:** at least 32 ETH and some ETH for deposit transaction fees * **Wallet**: Metamask installed {% hint style="info" %} :bulb: For examples of actual staking hardware builds, check out [RocketPool's hardware guide](https://github.com/rocket-pool/docs.rocketpool.net/blob/main/src/guides/node/local/hardware.md). {% endhint %}

Ethereum Staking Node

{% hint style="success" %} :sparkles: **Pro Validator Tip**: Highly recommend you begin with a brand new instance of an OS, VM, and/or machine. Avoid headaches by NOT reusing testnet keys, wallets, or databases for your validator. {% endhint %} ## :desktop: Local Node vs Remote Node **Decision**: Do I run my Ethereum staking node locally at home or rent a VPS cloud server remotely? Here's a list of criteria to help you decide. | Criteria | Local Node | Remote Node | | :------------------: | -------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Ongoing Costs | Plus - No fees, besides internet bill and electricity. | Minus - Monthly or Annual reoccurring rental fees. | | Hardware Maintenance | Minus - Do it yourself if hardware issues. | Plus - Included, covered by hosting provider. | | Internet | Minus - Can slow down home internet and use up data plan (if not unlimited) Budget for at least 2TB per month data plan. | Plus - Often plans are generous and more than sufficient for an ETH node. | | Reliability | Minus - Do it yourself with UPS, redundant internet connections, computer issues | Plus - Hosted in a data center with multiple power/internet backups. | | Barrier to Entry |

Plus - Can re-use or re-purpose existing hardware

Minus - Initial cost to purchase new computer equipment

| Plus - Renting a VPS might require a lower initial investment as you can pay monthly. | | Decentralization | Plus - Home staking is the **gold standard** for Ethereum decentralization, nothing bets it! | Minus - VPS cloud hosts like [Netcup](https://www.netcup.eu/bestellen/produkt.php?produkt=3026) or AmazonWebServices are by nature more centralized. | | Customization | Plus - More fine control over hardware configuration | Minus - May be limited choices and hardware can be shared. For example, a common issue is insufficient disk storage I/O speeds (IOPS). | | Security | Plus - As secure as your home and personal [OPSEC](https://en.wikipedia.org/wiki/Operations_security) |

Plus - Enterprise-grade, professional data centers.

Minus - Not your hardware, not your node. It's possible the hosting provide can view your node's contents.

| | Freedom |

Plus - Do whatever you want. Plan your own upgrades.

Minus - With great freedom and power, you are solely responsible for your node.

|

Plus - Professionally managed.


Minus - At the mercy of the host's actions, data center outages are possible.

| ## :tools: Setup Ubuntu With your local or remote node, now you need to install an Operating System. This guide is designed for Ubuntu 22.04 LTS. * To install **Ubuntu Server**, refer to [this guide.](https://ubuntu.com/tutorials/install-ubuntu-server#1-overview) * To install **Ubuntu Desktop**, refer to [this guide.](https://www.coincashew.com/coins/overview-xtz/guide-how-to-setup-a-baker/install-ubuntu) {% hint style="info" %} **Recommendation**: A headless (no monitor) install of **Ubuntu Server** on a **dedicated** NUC/laptop/desktop/VPS is best for ease of reliability and security. :fire: Do not use this system for email/browsing web/gaming/socials. :fire: {% endhint %} {% hint style="warning" %} **Tip**: When installing Ubuntu Server, ensure you are selecting “**Use an entire disk**” on the **Guided storage configuration** screen. Next screen will be the **Storage configuration** screen, ensure your settings are using all available disk storage. A [common issue](/coins/overview-eth/archived-guides/guide-or-how-to-setup-a-validator-on-eth2-mainnet/part-iii-tips/using-all-available-lvm-disk-space.md) is that Ubuntu server defaults to using only 200GB. {% endhint %} ## :performing\_arts: Setup Metamask When the time comes to make your validator's 32ETH deposit(s), you'll need a wallet to transfer funds to the beacon chain deposit contract. * To install Metamask, refer to [this guide.](https://www.coincashew.com/wallets/browser-wallets/metamask-ethereum) ## :jigsaw: High Level Validator Node Overview {% hint style="info" %} At the end of this guide, you will build a staking validator node that hosts three main components in two layers: consensus layer consists of a consensus client, also known as a validator client with a beacon chain client. The execution layer consists of a execution client, formerly a eth1 node. **Validator client** - Responsible for producing new blocks and attestations in the beacon chain and shard chains. **Beacon chain client** - Responsible for managing the state of the beacon chain, validator shuffling, and more. **Execution client (aka Eth1 node)** - Supplies incoming validator deposits from the eth mainnet chain to the beacon chain client. {% endhint %} ![How eth2 fits together featuring Leslie the eth2 Rhino, the mascot named after American computer scientist Leslie Lamport](/files/-MPCDQuE1PFqzrv0AzuT) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
