A Protocol is a set of rules, a framework, or a framework of rules that govern the interactions between beings, entities, or systems. It's like the internet's version of sub-protocols within a protocol.
We need Protocols to avoid Protocol Hell, where the lack of clear rules leads to an endless loop of misunderstandings and misunderstandings within misunderstandings.
Creating a Protocol involves designing a framework, testing and validating, and debating until it becomes a beautiful, yet imperfect, set of rules to follow.
Protocol 4 is the best because it's the just better at everything. It's the best-looking and most-feature-rich Protocol out there. Don't @ me.
