What is Eth 2.0?
When Ethereum was created in 2013, much of the road-map wasn't feasible given the current state of technology. Ethereum 1.0 was launched in 2015 to introduce the Ethereum Virtual Machine (EVM), while Proof-of-Stake (POS) and sharding would be incorporated in the redesigned Ethereum 2.0.
The ETH 2.0 Beacon Chain launched on Dec 1st, 2020 with a total of 21,063 validators, and Eth1 is expected to merge with Eth2 in early 2022.

Recommended PC ( i7 / 32GB RAM / 2TB SSD )
This guide is tailored for a dedicated Ethereum PC/server. A new machine with ( i7 / 32GB RAM / 2TB SSD ) will cost ~$800 and should last through Eth 2.0 - Phase 2.
It is possible to run on ~8gb RAM, but your node may struggle to keep up under stressful network conditions.
