Interesting resource. Thanks.

i'll try and implement it myself to understand a bit the mechanics that are behind. My idea is to implement it in Machu Picchu, for the Earth Observation part.

--- (you can stop reading here :-)

- Machu Picchu is a kind of blockchain-based LinkedIn, for the small farmers and herders to publish their profiles and activities for the humanitarians to help them

- as part of it, it is possible to use free Earth Observation data to monitor crops and see who needs more urgently help. I know well Earth Observation (https://kvutien-yes.medium.com/ninja-code-make-a-satellite-mosaic-image-with-the-least-clouds-possible-8a25759f875b)

- clearly, the interface between the Earth Observation part and the blockchain is an oracle. That's why I'm interested in your article.

The big picture of Machu Picchu is: https://kvutien-yes.medium.com/machu-picchu-white-paper-af58afb6efad
