After watching the given video, I have had deeper understanding on Horizen's Secure Node and its mechanism to protect network from attacks.
Furthermore,
I wanna know that whether the Horizen project has opened new signature campaign with new signature codes or not.
Thanks in advance.We don't have active campaigns currently.
We have signatures still under construction but you can help us in testing..
There are no bounties for such efforts.
If you wear signature you are doing this as supporter of this project.

Thanks!
Signature campaigns in the future are not excluded
All info will be announced here and new appropriate topic will be opened for such purpose.
So stay tuned.
