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 stay up for sharing with you all.
Because you’ll have the ability to learn the total 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 important 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 would’ve been exploited by a malicious attacker to trigger severe disruptions to the chain 😳
This tells us…
We might actually profit from higher useful check protection round our validation logic to verify we’d 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 of this taking place. That would imply documenting all modifications, or having 2 individuals carry out the merge individually then evaluating outcomes, or a change to how we method the code evaluations.
The audit was a extremely good concept (thanks Quarkslab!)
There have been additionally some smaller findings, and a few nice ideas 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 will 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 are able to then all examine the outcomes after which signal the discharge, certifying that all of us agree that the revealed launch is protected & correct.
There’s loads of magic concerned to make this work, which results in a time-consuming & usually irritating expertise (particularly for n00bs like me). So I actually dragged my ft 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 I lastly compelled myself to push by means of this just a few days in the past, and after combating with some outdated scripts, was in a position to construct the entire binaries efficiently.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.
After plenty of guarantees after which take-backs, I’ve lastly determined to launch a binary that enables non-technical customers to check out the MWEB testnet. I solely have the home windows launch out there 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 when you’d wish to confirm the binaries first (it is 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 by chance 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 inform by the off-colored emblem 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 may CPU mine a block very quickly), or discover somebody to present you some. If anybody is prepared to setup a faucet, I’ve acquired a ton of cash you may have 🙂
Additionally, if somebody looks like writing a information for 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 individual.
You’re just about again to simply ready on me once more ⏱
whereas I end making use of audit ideas after which pushing by means 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 may 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 😅
