No, not really. The US financial system does it using SFTP and tech from the 70’s just fine.
All the stuff you’re talking about is only useful when it’s nothing but distrusted counterparties with no trusted intermediaries, no place anywhere someone can store a copy of the data they trust, etc. which pretty much never happens in the real world.
All these issues got worked out a long time ago in ways that really do work fine. It’s a bit slow, but it works.
Most of the things you’re talking about also have big disadvantages for real world players (no one generally wants all transactions stored forever and visible to everyone for instance, or for transactions to be immutable even if there was fraud or fat fingering).
Where it CAN be useful is where the existing power structure is actively trying to destroy trust in any active institutions or actively driving the economy off a cliff bandit style, but is also unable to clamp down on internet connections.
Which does have some niche uses, and it might be more than that at some point. But right now it’s just not well fit for purpose compared to the equivalents.
