It looks legitimate to me, but not particularly exciting. Quantum-resistant public-key cryptography and digital signature algorithms are well established: https://en.wikipedia.org/wiki/NTRUSign Hence, making bitcoin quantum-resistant is relatively straightforward by replacing the ECDSA algorithm with NTRU; everything else remains essentially the same. The paper proposes using hash-based signatures rather than lattice-based signatures. I'd personally trust lattice-based cryptography more since the underlying problem has been proved NP-complete. By comparison, secure hashes often tend to have insecurities enabling these sorts of things to happen: http://shattered.it/ Best wishes, Adam P. Goucher

https://github.com/theQRL/QRL/blob/master/QRL_whitepaper.pdf anyone know if this is rational or are these guys blowing smoke?

thanks
