Ethereum 2.0 is meant to overcome current obstacles in scalability and accessibility that hinder the community from mass adoption. The CryptoKitties craze of 2017 showed how explosive demand on a single decentralized app on the Ethereum blockchain may congest the entire community.

We asked earlier what other functions could be built with blockchain expertise. If a digital world is created — for gaming, or for any variety of different causes — blockchain expertise could permit users to purchase and own items of that virtual world, similar to they could purchase a plot of land.
