No, because "crypto" is only a subset of "blockchain."

Blockchain can be used for a lot more than just digital cash. It can be used for storing immutable logs of any data/content. That implies endless use-cases.

Yes, transactions can be viewed as contracts, but the mediation is already accounted for by that specific blockchain's consensus algorithm & proposal/dispute resolution system. Most of the good smart contract blockchains already have systems in place for all this.

You've got it backwards, "crypto" is cryptography which is where all of this comes from. "Blockchain" is just a clever combination of ECDSA, Merkle trees and partial hash inversion that has proven useful to implement decentralized digital cash. I think we would be better served by looking at existing real-world problems with fresh eyes to see if cryptography can provide unique solutions, rather than taking one particular protocol template and assuming it can be used for almost anything.

> "crypto" is cryptography

It ought to be, and it used to be, but unfortunately it's been hijacked by the cryptocurrency community to such an extent that it's become increasingly ambiguous.

> ECDSA

or, preferrably, Schnorr signatures.

> partial hash inversion

There's more to mining than hashing [1].
