Hey Spammer!
From what I understand, you want to organize something like anonymous "people's CIA"? right?
If yes, then your "PPI" system is too complicated.
All you need are simple wishlists:
***
I would donate for:
mission - price
mission - price
***
"Agents" will track user's lists and fullfill the highest paying missions.
And there is absolutely no need to waste money!
User can demonstrate his/her determinition to pay by making donations to well-known charity organizations.
For example, every month: pay for completed missions - update and publish new wishlist - make small donation.
(...but, if you really give bitcoins, here is my address bc1qgrh4pvj0lhf0nm264sppuwa9l8pc6q2tys0vgc)
Maybe you're right, but one mission=one address is more accurate. In the future it may become the basis for automatic AI/IoT systems. ... CIA is Central, more correct would be DIA - decentralized.
How to verify if its the "agent" that recieve the donation? This 12h32Tf9DPGX8qFhThYoZky9SCM9oENYuG empty address is obviously open to most people who read the message. Would not the compromision lead to lack of motivation to solve the task?
It was a fun riddle to solve though! Stumbled upon it in some transactions.
