A Grin (GRIN) developer funded by the Litecoin Basis has steered an answer for fixing the “Achilles heel of Mimblewimble privateness.”
David Burkett, a developer at Mimblewimble’s (MW) privacy-centric coin Grin, started a thread on month-to-month updates detailing progress on each Grin’s growth and the combination of MW’s privacy-focused know-how into Litecoin (LTC). The developer announced the information on Twitter on Dec. 1:
“I will be posting month-to-month standing updates detailing progress on the LTC MW EB (YAY acronyms). That is geared towards these fascinated by LTC growth, however may even speak rather a lot about Grin++ modifications, so it could be fascinating to Grinners as nicely.”
Burkett challenges the “Achilles heel of Mimblewimble privateness”
By way of Grin’s progress, the developer has purportedly carried out the first-ever pre-broadcast MW CoinJoin that may allegedly make transactions extra personal by disabling broadcasting earlier than transactions joined others within the CoinJoin block. Burkett famous that this challenge is among the most important issues related to MW’s privateness. He wrote:
“The Achilles heel of mimblewimble privateness although, has at all times been that transactions are broadcast earlier than they’ve had an opportunity to be joined with different transactions. Meaning nodes monitoring the community can see the unique input-to-output hyperlinks of most transactions. Sending a transaction on to a CoinJoin server earlier than broadcasting is one among many alternative strategies we will use to fight that.”
Some researchers declare that there isn’t any solution to repair Mimblewimble’s privateness
The implementation follows a latest report claiming that MW’s privateness is “basically flawed” as a developer managed to trace 96% of Grin transactions earlier than they got here to CoinJoin, a block that collects all MW’s transactions to make sure their anonymity.
Revealed by Ivan Bogatyy at blockchain analysis agency Dragonfly Analysis, the report claims that there isn’t any solution to repair that challenge for MW, and the protocol ought to now not be thought-about as a “viable different to Zcash or Monero relating to privateness.”
Litecoin Basis is funding Burkett’s efforts to combine Grin’s privateness
Alongside Grin’s developments, the developer confirmed that the Litecoin Basis might be funding his efforts to implement the MW extension block in addition to to proceed his work on Grin. Litecoin creator Charlie Lee announced the initiative on Oct. 30.
Burkett additionally famous that he has been working with Lee and Bitcoin researcher Andrew Yang (not the presidential candidate) for a number of months to design a Mimblewimble extension block to allow confidential transactions on Litecoin. As such, the authors published two draft Litecoin Enchancment Proposals utilizing the MW protocol on Oct. 22.
In mid-November, Grin received an nameless 50 Bitcoin (BTC) donation to its Basic Fund, sparking a rumor that the donation was associated to Bitcoin creator Satoshi Nakamoto.
