What is Holochain doing?

I'm curious to know, what exactly is Holochain up to? It's been making quite a buzz in the world of cryptocurrency and finance lately. Could you elaborate on their mission, technology, and how they aim to disrupt the current landscape? Are they building a decentralized application framework? And how do they plan to achieve scalability and security in their approach? I'm eager to understand the unique selling proposition of Holochain and how it can potentially revolutionize the way we conduct transactions and manage data in the digital age.
