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 received’t dive too deeply into the findings right here. However at a fast look:
There was one vital concern 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 critical disruptions to the chain 😳
This tells us…
We might actually profit from higher purposeful check protection round our validation logic to verify we might catch comparable points ourselves in future releases.
We should always take into consideration including some processes we are able to observe to reduce the potential for 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.
The audit was a very good concept (thanks Quarkslab!)
There have been additionally some smaller findings, and a few nice options for a way we might enhance the standard and security of the code. Total, 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. Because of this a number of folks can all construct the code on completely different machines (and even completely different working programs) and nonetheless get the identical precise launch binaries. We are able to 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 loads of magic concerned to make this work, which ends up in a time-consuming & typically irritating expertise (particularly for n00bs like me). So I actually dragged my toes on this one 😬
. I lastly compelled myself to push by this a couple of days in the past, and after combating with some outdated scripts, was capable of construct all the binaries efficiently. I’ll end signing these tomorrow and hand them off for the opposite builders to repeat the construct & confirm outcomes.
After a lot 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 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 should you’d wish to confirm the binaries first (it’s best to). I’ll add directions on how to do this on the discharge web page when I’ve a while.
There’s no installer, as a result of I didn’t need anybody unintentionally changing their precise litecoin pockets, so to make use of it:
- Obtain (and confirm) the zip file
- Extract the
- Discover and run
litecoin-qt.exefrom 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 should mine a block to get mwebtest cash (you possibly can CPU mine a block very quickly), or discover somebody to provide you some. If anybody is prepared to setup a faucet, I’ve obtained a ton of cash you possibly can have 🙂
Additionally, if somebody appears like writing a information for learn how to create stealth addresses, ship to and obtain from them, and all the enjoyable stuff that goes together with it, you’d be my new favourite individual.
You’re just about again to only ready on me once more ⏱
whereas I end making use of audit options after which pushing by the tedious strategy of merging, coordinating closing opinions, 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 person who asks me 😜
What a protracted journey this has been 😅
