The Litecoin MimbleWimble testnet is on track for a launch in September and is fully making progress to enhance the scalability and privacy of the LTC network. However, the price of this cryptocurrency continues to disappoint and now resembles “a slippery shape” according to many analysts.
The developer behind Grin, David Burkett, is also working on this new implementation on the Litecoin network. As he shared in the Litecoin news, the Litecoin MimbleWimble testnet is coming by the end of Q3 of 2020 which means September this year.
In June, the developer wrote very minimal implementation that supports MW transactions as the existing LTC mempool logic ended up being more complex than the developer thought at first. As such, this would be something to revisit after the testnet launch.
Code was written to support the mining extension blocks. However, they need a lot more testing and a few “edge cases which are still left to be handled.” When talking about his concerns on the day, Burkett noted that “it was originally designed this way to be a clean separation from the existing code, to facilitate merging future bitcoin commits.”
Because separated databases “are a bad idea,” they don’t have the ability to make atomic updates. This can lead to many problems, some which can be exploitable by remote attackers. This is why Burkett decided to take more time and modify the code by serializing and deserializing MW blocks and transactions to disk. In the latest cryptocurrencies news, he said:
“As a result, upgraded nodes can successfully save extension block data to disk the same place they’ve always saved blocks, without having to introduce an additional database.”
However, the side effect of all these changes is that it was relatively straightforward to add support for sharing MimbleWimble transactions over the P2P network which is the first step towards the July goal of handling MW data.
At the end of the day, the Litecoin MimbleWimble testnet is being worked on and the big plan for the summer remains the same, including a lot of testing and redevelopment – hopefully with good progress as so far.
