# What is a Pulsechain Validator? Most people are familiar with Bitcoin or Ethereum Mining (Proof of Work). After Ethereum upgraded to Proof of Stake, a "miner" is now called a "validator." Instead of buying mining rigs (multiple computers), you can buy 1 computer and set up many validators, so long as you have 32 ETH (\~$60,000) per validator. It's quite expensive to run an Ethereum Validator. Pulsechain is a fork of Ethereum and instead requires 32,000,000 (32M) for 1 validator (\~$3,000 at todays market value). The APR depends on many other validators there are, however you can check out the latest Pulsechain Validator APR [here](https://launchpad.pulsechain.com/en/). --- # 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.
