What is casper conflict?

The Casper conflict refers to the ongoing debate within the Ethereum community regarding the implementation of the Casper proof-of-stake consensus mechanism. It aims to transition Ethereum from a proof-of-work system to a more energy-efficient proof-of-stake model. The conflict arises from differing opinions on the design, security, and scalability implications of the proposed changes. This transition is seen as crucial for Ethereum's long-term sustainability and performance.
