Write a webAuthn Identity Provider

✋ this task is blocked by “add a halo2 verifier” ✋

The objective here is to deploy a smart contract which verifies proofs from WebAuthn signatures, using the secp256r1 curve.

WebAuthn is a standard allowing users to authenticate and sign messages using the secure enclaves of their smartphones. The sepc256r1 curve is used on Apple's Face/Touch ID devices, Intel secure enclaves, Yubikey authenticators, and more.

Hylé does not specify what an "account" is, or even what identity particularly means. This gives it unprecedented flexibility in handling identity, including: - EOAs like Ethereum native wallets - Smart accounts of any kind - Regular web2 identity - Passports & other national identity documents (read more here: https://docs.hyle.eu/use-cases/for-identity-providers/). Supporting the verification of these proofs on Hylé would mean users could sign transaction on Hylé simply by using Face ID.

There is a library showcasing how to generate a halo2 proof of a secp256r1 signature: https://github.com/zkwebauthn/webauthn-halo2.
