I want to get a group element h for an eliptic curve, (specifically secp256k1)$h$ on the elliptic curve secp256k1. The important thing is that no one should know the dlogdiscrete logarithm of h$h$ with respect to g$g$. That is h, $h$ should be created from a public beacon and not by exponentiating g$g$. What's the best way to do this?
