Ethereum 2.0 is a multi-phase network upgrade of Ethereum which translates from Proof of Work (PoW) based on computing power (miners) and electricity (work) to build blocks on the blockchain to Proof of Stake (PoS) relying on validators (virtual miners) with Ethereum staking. In this new network topology the way you can earn Ethereum is by becoming a Validator and running an ETH 2 client that validates transactions in order to earns rewards.
If you want to become a Validator on Eth2 you will need to make use of a variety of infrastructure prerequisites, either on-premise, in the cloud or something in between. The first thing that you will need to prepare is to get the hardware on which you will run your Ethereum client and node. We will take care of those aspects in a later post and for the moment will prepare the hardware for it.
The minimum hardware requirements to be able to run an Eth2 node and its related software is as following:
While this will get you run the Eth2 node considering the future development on the network and other developments, it would be better to go with the recommended hardware specs for it.
I don't know how many will opt'in for cloud based solution, but I think that most of participants will go with the on-premises option. That way you can have full control on your hardware and software and can monitor everything from the comfort of your house. You can put the security measures in place that you usually do or add new layers on top of that.
Now getting back to the hardware that you need to run your Eth2 node, let's see what compact PCs that are on the market that you can use. I would rather use one small piece of hardware with just the specs needed, instead of a tower PC, laptop or others alike. Based on your budget and preference you can with one or the other or search for some similar systems. Having a dedicated mini PC with an UPS attached should be enough for running your node.
This is the first prerequisite that you need to take care before moving on with the other steps to setup you Eth2 node. I will continue in a next post the choosing and installing your Eth2 client to run your validator.
