The past few years? Wild ride for tokenized cash infrastructure. Blockchains aren't the clunky beasts they used to be—wallets got smarter, on-chain analytics became actually readable, and security tightened up without sacrificing speed.

What was experimental is now battle-tested. The rails are there. The question isn't whether the tech works anymore—it's who'll build the killer apps on top.
