I am looking for the best blinded signature scheme similar to:
http://anoncvs.aldigital.co.uk/lucre/
Are there any based on ECC. I am particularly interested in any libraries that already do the work.
Darn, it really doesn't look like there are any implementations other than the one you provided and maybe some for RSA. There are a bunch (http://crypto.stackexchange.com/questions/2424/which-blind-signature-schemes-exist-and-how-do-they-compare) of papers (http://blog.cryptographyengineering.com/p/note-on-blind-signature-schemes.html) for blinded signatures with various DSA signature schemes. Still that would require hiring a cryptography expert to actually implement that properly. Seems like BitShares Vote isn't coming anytime soon. :(
Edit:Hmm, I found this paper (http://www.ijimt.org/papers/556-IT302.pdf) and apparently someone has attempted to implement the cryptography in that paper in Go over here (https://github.com/mndrix/btcutil) which seems like a very simple implementation. After actually reading through it, I wouldn't trust that paper.
I remember Oleg Andreev working on an ECC blind signatures scheme.

It seems he has a working implementation based on obj-c.
