Litecoin MimbleWimble June Replace

Good / Dangerous information everybody! We’re formally half method via 2020 and with June now behind us, David Burkett, the challenge chief for the Litecoin MimbleWimble implementation has revealed one other growth replace so let’s soar 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 is 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 experiences ‘there are just a few edge circumstances left to deal with, and way more testing is required’. There have been just a few considerations raised on this replace nonetheless 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 option to be a clear separation from the present code, in an effort to facilitate merging future bitcoin commits. Having separate databases is usually a nasty concept although, as a result of we lose the power to make atomic updates, which suggests the two databases might grow to be out of sync. This could result in an entire host of issues, probably even ones which might be exploitable by distant attackers.”

Because 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 benefit from the groundwork that was laid down as a part of the segwit enhancement, to cleanly help serializing the extra information with out making main modifications to the present block storage format. Consequently, 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 aspect 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 aim 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 monitor with July specializing in the preliminary block obtain, August, Chain reorg logic and September the Activation logic and launch of the test-net.
