why don't we have campaigns using lightning network in the forum yet?
probably the LN developers have not picked interest in offer bounties.
What is necessary to make a signature campaign that would pay users using lightning network?
You need some coin/token reserve to share to participants, you the an announcement thread, you need signature codes and a bounty manger.
Not necessarily a significant campaign, could be something different..
Yes, it can be other campaign as well.
The idea would be to have micropayments weekly, the channel would only be closed at the end of the campaign. It would be a nice use of the this new tech
.
The idea is good and it shall receive interests from members here.
