Which blind signature schemes exist, and how do they compare?

WebRSA blind signatures. Traditional RSA signatures have the form S = M^d mod N, where M is the message, (N, e) is the public key, and d is the secret key, selected such that for any m: m^ {e*d} = m (see here for details on how keys are constructed).
