Blind Hash Signatures?

Question

Is it possible to implement blind signatures with purely hash-based signature algorithms?

Any whitepapers, code samples, etc on the subject would be helpful.

Answer 1

It's impossible:

Impossibility of Blind Signatures From One-Way Permutations - Katz, Schroder, Yerukhimovich

Answer 2

Till today, there is no known construction for this. The problem is that standard hash functions do not come with the necessary algebraic properties required for blinding and unblinding.
