Various EC developments:

* BLS12-381, a pairing-based curve for 128-bits security, proposed for Zcash:

* Another writeup of a VRF using Chaum-Pedersen and elliptic curves
(similar to CONIKS, VXEdDSA, etc):

* Nice writeup of small subgroup attacks against JOSE, apparently 5
libraries were vulnerable to this (?!)

* 21st Workshop on Elliptic Curve Cryptography:
