What is account abstraction in crypto?
Could you elaborate on the concept of account abstraction in the realm of cryptocurrency? I've heard it mentioned in discussions but am still unclear about its precise meaning and implications. As a financial practitioner, I'm curious to understand how this concept could potentially shape the future of digital assets and transactions. Is it a technical advancement that aims to enhance privacy, scalability, or both? How does it differ from traditional account models we're familiar with? Clarifying this notion would be highly beneficial for my understanding of the cryptocurrency ecosystem.
