Litecoin MimbleWimble October Recap Replace

This replace was written and offered by Litecoin MimbleWimble lead developer David Burkett.



Quarkslab has completed their audit of the code! 🚀

I’ll be assembly with them Friday to debate their findings. After that, they’ll work on releasing the audit report in a weblog put up, which I sit up for sharing with you all.


Because you’ll be capable of learn the total report as soon as they share their weblog put up, I gained’t dive too deeply into the findings right here. However at a fast look:

There was one essential subject discovered that resulted from a mistake whereas merging the MWEB code & v0.21.1 code collectively. So when copying the adjustments into the most recent launch code, I missed a small, however essential line of validation code that would’ve been exploited by a malicious attacker to trigger severe disruptions to the chain 😳

This tells us…

  1. We may actually profit from higher useful take a look at protection round our validation logic to ensure we might catch related points ourselves in future releases.

  2. We should always take into consideration including some processes we will comply with to reduce the potential of this taking place. That would imply documenting all adjustments, or having 2 individuals carry out the merge individually then evaluating outcomes, or a change to how we method the code evaluations.

  3. The audit was a very good thought (thanks Quarkslab!)

There have been additionally some smaller findings, and a few nice strategies for the way we may enhance the standard and security of the code. General, they had been impressed with the code high quality, which was thrilling to listen to 🥳

v0.21.1 (Taproot) Launch

The launch course of 5 we inherited from bitcoin may be fairly painful. It makes use of gitian 4 to construct repeatable and deterministic binaries from the supply code. Because of this a number of individuals can all construct the code on totally different machines (and even totally different working programs) and nonetheless get the identical actual launch binaries. We will then all examine the outcomes after which signal the discharge, certifying that all of us agree that the revealed launch is secure & correct.

There’s a variety of magic concerned to make this work, which results in a time-consuming & typically irritating expertise (particularly for n00bs like me). So I actually dragged my ft on this one 😬
. I lastly pressured myself to push by way of this a number of days in the past, and after combating with some outdated scripts, was in a position to construct the entire binaries efficiently. I’ll end signing these tomorrow and hand them off for the opposite builders to repeat the construct & confirm outcomes.

MWEB Testnet

After a number of guarantees after which take-backs, I’ve lastly determined to launch a binary that permits non-technical customers to check out the MWEB testnet. I solely have the home windows launch accessible proper now, however I’ll work on getting binaries for Mac OS X on Friday. Linux customers can construct their very own, as a result of I’m drained 😝

Hyperlink: MWEB Testnet Launch 26

Right here’s my gpg key 8 if you happen to’d prefer to confirm the binaries first (it is best to). I’ll add directions on how to try this on the discharge web page when I’ve a while.

There’s no installer, as a result of I didn’t need anybody by chance changing their precise litecoin pockets, so to make use of it:

  • Obtain (and confirm) the zip file
  • Extract the litecoin-63fe928e4e8a folder
  • Discover and run litecoin-qt.exe from contained in the bin folder

It will default to utilizing the MWEB testnet, which you’ll inform by the off-colored brand and the [mwebtest] within the title bar. These use mwebtest cash, not precise litecoin cash. So pleeease don’t attempt to use it with actual cash.

You’ll both need to mine a block to get mwebtest cash (you may CPU mine a block very quickly), or discover somebody to provide you some. If anybody is keen to setup a faucet, I’ve received a ton of cash you may have 🙂

Additionally, if somebody seems like writing a information for learn how to create stealth addresses, ship to and obtain from them, and the entire enjoyable stuff that goes together with it, you’d be my new favourite particular person.

Remaining Schedule

You’re just about again to only ready on me once more ⏱
whereas I end making use of audit strategies after which pushing by way of the tedious technique of merging, coordinating remaining evaluations, writing launch notes, and eventually kicking off the beloved gitian builds. I don’t know precisely how lengthy that can take, however rumor has it that it will increase by a full day for each individual that asks me 😜

What a protracted journey this has been 😅

P.S. 132 is updated.
