Everyone calls them financial rails, sure. Yet their actual architecture is far more radical: decentralized systems that operate independently across thousands of nodes. The immediate application? Tracking money and ownership worldwide. But honestly, that's just the beginning. The infrastructure itself enables trustless accounting at global scale, which opens doors to countless use cases beyond payments.
