The core innovation of Golden is how it achieves public verifiability in a lightweight manner, allowing all participants to non-interactively verify that all other participants followed the protocol correctly.
For this reason, Golden can be performed with only one round of (broadcast) communication.
I'm no cryptographer, but I think this is pretty cool. A lot of the distributed key generation protocols require all parties to participate in a number of rounds -- which is a clunky process. But this seems to get it down to users each broadcasting once. Cryptography is basically magic with math.
