On March 1, David Burkett, developer of Grin (GRIN) and Litecoin (LTC) cryptocurrencies, estimated that Mimblewimble’s privacy protocol would see a Litecoin beta release before the end of the summer.

In an update to the Mimblewimble Progress (MW) thread on Litecointalk.io, Burkitt reluctantly predicts that MW will start in the test network before September.

“I was still very hesitant to give specific dates when something was done, because writing a blockchain program is a complex, time-consuming and sometimes unpredictable task. I did not want artificial deadlines that forced us to speed up codes and introduce bugs or loopholes. Umniah. That said, I think it’s finally time to get back to the first big event. ”

David expects the test network release to include all the rules for validating and blocking transactions, basic peer-to-peer messaging features, synchronization, transaction aggregation and block mining.

Burkitt confirms that the release does not include a GUI wallet and expects transactions to be generated manually.

Burket publishes a Litecoin Improvement Proposal
The developer has also posted a Litecoin optimization proposal on Github that introduces one-way MW transactions and bug fixes since the previous proposal. Despite the progress, David says there is “much more to do”.

“I made some changes to the original core design to allow a soft fork for new features in the future. I also started making Merkle Ridges (MMR), which is the data structure we use to stick to the core and output. When MMR is a Once the logic is complete, I can return to the blocking logic. ”

Litecoin will collaborate with Burkett in 2019
In September 2019, the Litecoin project announced that it had commissioned Grin ++ David Burkett to implement MW support for the Litecoin network. The aim of the protocol change was to ensure Litecoin’s privacy, while MW was to facilitate confidential transactions.

MW opened to the world in August 2016 when a man who traded under the pseudonym Tom Elvis Jedusor posted the original MimbleWimble document on the Bitcoin Research Channel. The alleged author has not posted any posts since.

The protocol is designed to improve the privacy, scalability and interoperability of a blockchain. Through a process called CoinJoin, several MW transactions are combined into one. Thus, MW blocks consist of a list of all input, output and signature data, with transaction data hidden from the external observers.

MW was originally intended as a Bitcoin update or side chain, and it was first implemented in Grin ++, which was launched in January 2019.
