At a glance it seems fair to say that this is both a cryptocurrency library and a cryptography library.

The only truly general purpose thing here is SHA256. Every protocol on its supported list starts with either "ethereum" or "evm", and to the best of my knowledge the other primitives have seen very little use besides cryptocurrency.

The Internet Engineering Task Force, which in particular standardizes TLS, has acknowledge my contributions for my contributions to the very generic and globally useful hashing-to-curve primitive: https://datatracker.ietf.org/doc/html/draft-irtf-cfrg-hash-t...

And BLS signatures are standards as well: https://www.ietf.org/archive/id/draft-irtf-cfrg-bls-signatur...

BLS signatures are general purpose, the only Ethereum specific thing is choosing which elliptic curves are used for public keys and which for signatures as well as a prefix before hashing inputs.

Similarly KZG polynomial commitments are generic, the Ethereum specific thing is the trusted setup ceremony which needs to be specialized per protocol.

The finite field backends and the elliptic curves supported are all generic as well: https://github.com/mratsim/constantine/blob/master/constanti...
