Conflicted about this, the purist in me says hell no but the realist says that’s probably for the best.

Curious what you see as the downside?

He is probably talking about the fact that Passkeys uses a NIST-approved curve Which is something that Satoshi avoided on the suspicion of hidden backdoors But the reality is that Apple and Google only use NIST-approved curves for their secure enclaves Passkeys is needed for Web3 mainstream adoption

Interesting.Whenever I hear curve my brain substitutes it for “math thing”. What could a back door in a curve look like? Is the assertion that its standard approved means that intelligence agencies are comfortable in they could brute force it if they had to?

Super interesting. So basically the concern is that in the past the NSA influenced NIST to use a curve that was generated with a secret value known to them, which let them predict outputs. Given that history any curve recommended by NIST is now suspect. I guess a KZG setup would mitigate this?

As long as the curve’s design is done transparently then it’s fine because others can review the motivation and decision process behind it Which is why ed25519 is so popular because of its transparency, safety and efficiency
