Litecoin and Mimblewimble protocol

2020.06.22 币圈资讯, 币圈资讯

The creator of Litecoin also offered a way in which users could face the problem pointed out by Bogatty:This limitation of MimbleWimble protocol is well known. MW is basically Confidential Transactions with scaling benefits and slight unlinkability. To get much better privacy, you can still use CoinJoin before broadcasting and CJ works really well with MW due to CT and aggregation.

Ivan Bogatyy published his report under the name “Breaking Mimblewimble’s Privacy Model”. In his publication he points out the intrinsic error of the protocol in making an attack that, according to Bogatty, could “track 96% of all addresses they send and receive (Litecoin) in real time”.

The crypto community has had different reactions to Bogatty’s report. Emir Gun Sirer, for example, said via his Twitter account that the report’s findings confirm that “Grin and Beam are no longer private coins”. The alleged attack and its conclusions were addressed by the creator of Litecoin.

The Grin team has consistently acknowledged that Grin’s privacy is far from perfect. While transaction linkability is a limitation that we’re looking to mitigate as part of our goal of ever-improving privacy, it does not ‘break’ Mimblewimble nor is it anywhere close to being so fundamental as to render it or Grin’s privacy features useless.
