Litecoin MimbleWimble June Replace

Good / Dangerous information everybody! We’re formally half manner by way of 2020 and with June now behind us, David Burkett, the venture 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 complicated’ than anticipated, as such it’s going to 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 help the mining of extension blocks which can retailer MimbleWimble transactions. Burkett reviews ‘there are a number of edge circumstances left to deal with, and rather more testing is required’. There have been a number of considerations raised on this replace nevertheless as Burkett writes:

“I’ve had considerations about the way in which we have been storing mimblewimble block information in a separate database. It was initially designed this approach to be a clear separation from the prevailing code, so as to facilitate merging future bitcoin commits. Having separate databases is usually a nasty concept although, as a result of we lose the flexibility to make atomic updates, which implies the two databases might turn into out of sync. This could result in a complete host of issues, probably even ones which can be exploitable by distant attackers.”

As a result 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 capable of reap the benefits of the groundwork that was laid down as a part of the segwit enhancement, to cleanly help serializing the extra information with out making main adjustments to the prevailing block storage format. Because of this, upgraded nodes can efficiently save extension block information to disk the identical place they’ve at all times saved blocks, with out having to introduce an extra database. A facet impact of those adjustments 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 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.
