- Litecoin Foundation funding the efforts to design a Mimblewimble extension block
- Grin++ developer David Burkett, finds a solution to combat the Achilles heel of MW privacy
As another step towards privacy on the Litecoin network, Litecoin Foundation is funding the efforts of David Burkett, Grin ++ developer who is working to design a Mimblewimble extension block to Litecoin so that LTC users can have confidential transactions and more fungible money.
As per the latest update, the team has been working for several months to implement the MW extension block and “great progress” has been made since it was announced.
Burkett has completed the LTC Dev Training Session and would be making the modifications necessary to get it to sync.
Once the appropriate modifications were made, he would design the Grin++ codebase that will allow Litecoin to reuse Grin++ with minimal changes. Currently, the design is beyond the scope of this update as such he will be writing up the design over the next few weeks.
From here on, he will be posting monthly status updates about the progress on Litecoin MW implementation.
Combating the Achilles Heel of Mimblewimble Privacy
Apart from the development with Litecoin, Burkett will also talk about the changes made to Grin++.
He has already implemented payments on it via TOR. Burkett explains that in order to build a transaction collaboratively, Mimblewimble needs to interact with the receiver. And by using TOR for the interaction, they can use familiar-looking addresses and a similar set-up with much better privacy.
Talking about Achilles heel of mimblewimble privacy, Burkett explained that transactions are broadcast before they have even had a chance to be joined with other transactions. This allows the nodes to see the original input-to-output links of most transactions.
But now, he has performed the first-ever pre-broadcast Mimblewimble CoinJoin, one of the many different techniques that can be used to combat that Achilles Heels.
