On Nov. 18, crypto researcher Ivan Bogatyy published an article on Medium claiming that he had found an extremely easy way of bypassing Grin’s Mimblewimble privacy protocol. As part of his efforts, Bogatyy stated that he was able to trace over 96% of all Grin-related transactions in real time, including the addresses of the senders as well as recipients associated with these sets of transactions.
What’s more striking is the fact that Bogatyy claims he was able to achieve all this by spending just $60 a week on Amazon (NASDAQ:AMZN) Web Services computational power, which helped connect him to Grin’s native blockchain nodes.
