Multi-signature contracts already exist in the real world. Just so you know, multi-signature contracts have been a requirement of real world contracts for several centuries.
Decentralized finance products also already exist. They're called microloans. Someone got a (memorial) Nobel prize for this in 2006.
Multi-party computation. Have you heard of SETI@home? It came out in 1999. It was followed by Folding@home in 2000.
So basically, all of the "innovations" of "crypto space" are just things that have already been done in the real world, but now are being done online less efficiently. I guess that's what counts for progress if you never bothered to learn history.
