Les crypto monnaies présentent une faille: lâattaque aux 51%.
Cette attaque est la possibilité pour un mineur ou un groupe de mineurs, de réussir à prendre plus de la moitié de la puissance de calcul totale du réseau. Cela leur permet alors dâimposer un nouveau protocole qui penche en leurs faveur. Ce genre dâexploit est censé être rarissime, en particulier pour les principales crypto monnaies.
Pourtant, au cours des deux derniers mois , cet exploit a été réalisé deux fois  sur la même Blockchain. Il sâagit de la monnaie virtuelle Verge, (qui a récemment fait parler dâelle à propos de son partenariat avec le site pour adultes, Pornhub.)
Verge a donc subi deux attaques aux 51% et les attaquants ont ainsi empoché des millions de dollars.Lors de la première attaque, en avril, le hacker a réussi à dérober 250000 XVG.
Ensuite, en mai, ce sont 1,7 millions de dollars qui ont été empochés par un autre attaquant.
