I think it is the issue where ecdsa is a NIST standard that was based on an elliptic curve provided by the NSA. As the NSA has been known to suggest poor cryptography primitives in the past, many groups recommend ed25519 (same process, different and more trusted curve generation process) Take a look at the "concerns" section of the wiki page. https://en.wikipedia.org/wiki/Elliptic_Curve_Digital_Signature_Algorithm?wprov=sfla1 https://en.wikipedia.org/wiki/Elliptic_Curve_Digital_Signatu...
