MingleJingle to launch on Litecoin testnet – new version of MimbleWimble

Litecoin developers are preparing to launch a new version of the MimbleWimble privacy protocol, MingleJingle, on the testnet, which supports completely non-interactive transactions.

Litecoin developer David Burkett in charge of MimbleWimble integration provided an update on its implementation. He said that significant progress has been made and the initial code will be ready and ready for review on March 15th.

“There are many more ways in which we can (and will) continue to improve the MWEB code, in particular with regard to synchronization. But most of what’s left is not required for the initial launch … I’ll submit the code for review on March 15th – wrote
Berkett on Twitter.

The MimbleWimble Litecoin project has been in development for over a year, and the MimbleWimble Extension Blocks (MWEB) testnet was launched last September. Burkett recently brought community attention to MingleJingle, a new offering from lead developer RandomX Tevador.

MingleJingle is a reworked original MimbleWimble protocol offering completely non-interactive transactions. This means that the sender only needs to know the recipient’s address, which is generated from the two public keys. Other important features include addresses that cannot be associated with wallets, as well as transaction outputs where addresses cannot be determined.

According to Burkett, Tevador’s extensive experience with Monero hidden addresses has brought a number of innovations to the project, as well as improved MWEB addressing and exit structure. Burkett added additional tweaks to the general mechanism for hiding transaction details, and said the code is now ready for the new testnet. It will contain all the consensus, P2P and wallet code required to support MWEB.

“The only thing that will not be there is an activation code, which I will add after all the checks and audits are completed,” he said.

Burkett hopes to activate the MimbleWimble update on the Litecoin mainnet in 2021, provided miners and node operators support him. The principle of MimbleWimble is that the block does not contain detailed information about all transactions, while they are confirmed, which also prevents double spending attacks. The proposed improvements will be implemented if more than 75% of the network participants vote for them.

In January 2019, the Grin and Beam blockchains were launched based on the Mimblewimble protocol.
