How does PulseX work?

Excuse me, could you please explain in more detail how PulseX actually functions? I'm curious about the underlying mechanisms that drive its operation and how it differs from other blockchain-based platforms. Specifically, how does it handle transactions, security measures, and the integration of smart contracts? I'm also interested in its scalability potential and how it aims to improve upon existing solutions in the crypto finance space. Your insights would be greatly appreciated.
