partly my aim for this AMA is to translate the more technical insights so that it will be understandable to everyone regardless of background. I think the recap above did not give justice to the 2-hour talk :( where i even elaborated my answers with examples. Even @lola.imma (i think) have grasped the ideas to the technical aspects of being a witness. I hope you can join us for the next episode ...it's about security and you can read more about it here
