Could you build this?
No Implementing a secure, pure-Python ECDSA library requires deep cryptographic expertise to correctly implement finite field arithmetic, elliptic curve point addition/doubling, and side-channel attack mitigations.
What it would actually take: Building a secure ECDSA library requires mathematical cryptography implementation from scratch. The code must implement big-integer modular arithmetic, projective coordinates for curve operations (NIST curves, secp256k1), RFC 6979 deterministic nonce generation, and constant-time algorithms to prevent timing and cache side-channel vulnerabilities, followed by formal verification and extensive test-vector validation against KAT (Known Answer Tests).
