これは生の暗号プリミティブによる署名と同様の結果を得られるのだろうか。例えば、Verifiable Credentialsにも使えたりする?

一方の`did:plc`は今のところsecp256k1とNIST P-256しか対応していないようなので、少なくとも手持ちのEd25519の鍵では無理そうである

that is.. a weird decision. Unless they have some requirement where they *need* signatures for key and data pairs to be unique, there should be no need to only support these curves

Off the rails rambling  

(also everything supporting the k256 curve feels like it's cluxed on because of blockchain ties??)

But technically they could also just implement Schnorr signatures over ristretto225 to have the same uniqueness guarantees. But that's a little more out there, so maybe support just isn't out there for libraries that match their quality criteria.

Understandable that they don't wanna impl it themselves and/or fund an audit, I guess when the alternative is a NIST curve
