RFC 8032: Edwards-Curve Digital Signature Algorithm (EdDSA)

EdDSA has been the gold standard for signatures in general, and elliptic curve ones in the specific, for a while now. It fixes many of the traditional issues with both DSA schemes and elliptic curves, resulting in a fast, short, easy-to-implement signature scheme.

This is important to people designing specifications or new cryptographic software. If you want strong signatures, use NaCl/libsodium -- that has come with EdDSA (Ed25519) for quite a while.
