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 publish, which I sit up for sharing with you all.


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

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

This tells us…

  1. We may actually profit from higher purposeful check protection round our validation logic to ensure we might catch related points ourselves in future releases.

  2. We must always take into consideration including some processes we are able to observe to attenuate the opportunity of this taking place. That might imply documenting all modifications, or having 2 folks carry out the merge individually then evaluating outcomes, or a change to how we strategy the code opinions.

  3. The audit was a extremely good concept (thanks Quarkslab!)

There have been additionally some smaller findings, and a few nice ideas for the way we may enhance the standard and security of the code. General, they have 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 could be fairly painful. It makes use of gitian 4 to construct repeatable and deterministic binaries from the supply code. Which means a number of folks 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 evaluate the outcomes after which signal the discharge, certifying that all of us agree that the revealed launch is protected & correct.

There’s a number of magic concerned to make this work, which ends up in a time-consuming & usually irritating expertise (particularly for n00bs like me). So I actually dragged my toes on this one 😬
. I lastly compelled myself to push by means of this just a few days in the past, and after combating with some outdated scripts, was in a position to construct the entire binaries efficiently.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 numerous 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 obtainable 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 wish to confirm the binaries first (you need 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 accident 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

This may default to utilizing the MWEB testnet, which you’ll be able to 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’ll be able to CPU mine a block very quickly), or discover somebody to offer you some. If anybody is prepared to setup a faucet, I’ve obtained a ton of cash you’ll be able to have 🙂

Additionally, if somebody looks 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 ideas after which pushing by means of the tedious strategy of merging, coordinating ultimate opinions, writing launch notes, and at last kicking off the beloved gitian builds. I don’t know precisely how lengthy that may 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 😅
