Litecoin MimbleWimble June Replace

Good / Unhealthy information everybody! We’re formally half approach by way of 2020 and with June now behind us, David Burkett, the mission chief for the Litecoin MimbleWimble implementation has printed one other growth 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 should must 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 assist the mining of extension blocks which can retailer MimbleWimble transactions. Burkett reviews ‘there are a number of edge instances 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 best way we have been storing mimblewimble block information in a separate database. It was initially designed this option to be a clear separation from the prevailing code, in an effort to facilitate merging future bitcoin commits. Having separate databases is usually a nasty thought although, as a result of we lose the power to make atomic updates, which suggests the two databases may turn into out of sync. This will result in a complete host of issues, doubtlessly even ones which are exploitable by distant attackers.”

On account of 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 reap the benefits of the groundwork that was laid down as a part of the segwit enhancement, to cleanly assist serializing the extra information with out making main modifications to the prevailing block storage format. Consequently, upgraded nodes can efficiently save extension block information to disk the identical place they’ve all the time saved blocks, with out having to introduce an extra database. A aspect impact of those modifications is that it was comparatively simple so as to add assist for sharing mimblewimble transactions over the p2p community, which is step one towards July’s objective of dealing with MW information as a part of the Preliminary Block Obtain.”

The long run growth 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 Venture.
