Litecoin MimbleWimble June Replace

Litecoin MimbleWimble June Replace

Good / Dangerous 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 revealed 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 is going to 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 instances left to deal with, and rather 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 information in a separate database. It was initially designed this solution to be a clear separation from the prevailing code, so as to facilitate merging future bitcoin commits. Having separate databases is mostly a foul thought although, as a result of we lose the flexibility to make atomic updates, which suggests the two databases might grow to be out of sync. This will result in a complete host of issues, doubtlessly even ones which might be exploitable by distant attackers.”

As a consequence 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 make the most 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. In consequence, 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 a further database. A aspect impact of those adjustments is that it was comparatively easy 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 observe with July specializing in the preliminary block obtain, August, Chain reorg logic and September the Activation logic and launch of the test-net.
