Litecoin MimbleWimble June Replace
Good / Unhealthy information everybody! We’re formally half approach via 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 can 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 just a few edge instances 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 knowledge in a separate database. It was initially designed this option to be a clear separation from the present code, with a view to facilitate merging future bitcoin commits. Having separate databases is mostly a nasty thought although, as a result of we lose the flexibility to make atomic updates, which implies the two databases may develop into out of sync. This may 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 capable of benefit from the groundwork that was laid down as a part of the segwit enhancement, to cleanly assist serializing the extra knowledge with out making main adjustments 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 a further database. A facet impact of those adjustments 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 purpose of dealing with MW knowledge as a part of the Preliminary Block Obtain.”
The longer term 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.
