Voici la réponse “officielle” de la communauté Grin : https://medium.com/grin-mimblewimble/factual-inaccuracies-of-breaking-mimblewimbles-privacy-model-8063371839b9 TL;DR: Mimblewimble privacy is not “fundamentally flawed”. The described “attack” on Mimblewimble/Grin is a misunderstanding of a known limitation. While the article provides some interesting numbers on network analysis, the results presented do not actually constitute an attack, nor do they back up the sensationalized claims made.
