Function contract::ndpc_utils::verify_signature

pub fn verify_signature(
    public_key: PublicKey, 
    signature: String, 
    message: String
) -> bool

Verify a signature of a message, which is signed by the given publicKey

Note : It only supports Ed25519 publicKeys, as the verifier for the Secp256k1 keys, would larger up the contract and it would not be practical
