Want to really get BitcoinFi? Don't just skim the documentation—dive deep into it properly. You'll find two critical mechanisms that make the whole system tick. First, there's the cross-chain flow architecture—what we call interoperability in technical terms. This isn't just some buzzword; it's the backbone enabling assets to move seamlessly across different blockchains. Second, the protocol design shows exactly how BitcoinFi bridges the gap between traditional Bitcoin and decentralized finance layers. Understanding these two pieces separately, then seeing how they work together, changes your entire perspective on what BitcoinFi actually solves.
