Litecoin MimbleWimble June Replace

Good / Unhealthy information everybody! We’re formally half manner by way of 2020 and with June now behind us, David Burkett, the mission chief for the Litecoin MimbleWimble implementation has revealed one other improvement replace so let’s bounce proper into it.

Beginning with mempool logic. Upon additional exploration Burkett states this space has confirmed to be ‘fairly a bit extra advanced’ than anticipated, as such it would should be revisited after the test-net launches this September.

“For now although, a really minimal implementation supporting MW transactions has been written.”

Moreover, code has been written to help the mining of extension blocks which can retailer MimbleWimble transactions. Burkett studies ‘there are a number of edge circumstances left to deal with, and way more testing is required’. There have been a number of considerations raised on this replace nonetheless as Burkett writes:

“I’ve had considerations about the way in which we had been storing mimblewimble block knowledge in a separate database. It was initially designed this option to be a clear separation from the present code, as a way to facilitate merging future bitcoin commits. Having separate databases is usually a foul thought although, as a result of we lose the power to make atomic updates, which implies the two databases might turn out to be out of sync. This may result in an entire host of issues, doubtlessly even ones which are exploitable by distant attackers.”

Resulting from these considerations, Burkett has ‘determined to spend a while modifying the code for serializing and deserializing MW blocks & transactions to disk’.

“I used to be in a position to make the most of the groundwork that was laid down as a part of the segwit enhancement, to cleanly help serializing the extra knowledge with out making main modifications to the present block storage format. Consequently, upgraded nodes can efficiently save extension block knowledge to disk the identical place they’ve all the time saved blocks, with out having to introduce an extra database. A facet impact of those modifications is that it was comparatively simple so as to add help for sharing mimblewimble transactions over the p2p community, which is step one towards July’s purpose of dealing with MW knowledge as a part of the Preliminary Block Obtain.”

The long run improvement MimbleWimble roadmap has now been up to date and stays on observe with July specializing in the preliminary block obtain, August, Chain reorg logic and September the Activation logic and launch of the test-net.

David Burkett is a publicly funded developer engaged on the Litecoin Core Undertaking.
